Description

The invention relates to a disposable medical garment with a longitudinal or carrying direction and a transverse or circumferential direction comprising a kittel- or tubular main body having an upper end, a lower end and arranged from the upper end in the longitudinal or supporting direction upper Hull area, a waist / hip area and a leg area and with a body-facing inside when wearing state and a body-facing wear state, the main part comprises a flat web material and having a circumferentially extending over the folded portion, wherein in the folded region, the flat web material has partial sections, which at least two fold edges extending transversely to the longitudinal direction are folded onto themselves in a zigzag shape, and wherein the folded area is releasably fixed on the manufacturer side such that the folded area is separated by the action of a pulling force K along the longitudinal direction. or support direction is unfoldable.

Disposable medical items of clothing according to the invention have many uses in the entire medical field, such as in particular as a garment for the doctor and other medical workers during medical examinations, during the visit, during surgery.

Such disposable medical garments are in particular disposable examination coats or examination gowns or even disposable surgical gowns or surgical gowns. They serve on the one hand to improve the hygiene or sterility towards the patient, and on the other hand to protect the wearer, in particular the surgeon from liquids and / or microorganisms, which occur during an examination, treatment, in particular surgery of a patient.

The unfolding of folded garments introduced into disposable medical garments by the manufacturer may increase the length of the garment as required, so that the need for several sizes, ie garments with different lengths for carriers of different sizes, can be covered with a garment thus provided. In addition, it may also be advantageous for certain applications to provide over the length expandable and thus largely over the entire longitudinal axis of a wearer extending garments, such as work of the wearer in a sitting position, thus preferably also the lower leg area up to the Feet to cover well.

Such disposable medical garments are known in the art. So revealed the WO 2006/038913 A1 a disposable protective garment, in which the originally provided shell length can be increased by dissolving folding arrangements, which are arranged along the lower jacket space. The US 2009/0031474 A1 discloses the features of the preamble of claim 1. Disposable medical garments are always applied with the utmost care by the wearer himself or with the help of another person in order to meet the hygiene requirements in general and in particular the sterility in surgical gowns and these to ensure.

With the present invention it has been recognized that the placement of folded areas and the possibility of deployment and thus extension of the disposable garment must be commensurate with the purpose of the disposable garment. Thus, it has been recognized that for the extension of disposable medical garments having pleated areas disposed along the lower mantle, the wearer must adequately protect himself in the direction of the floor so as to be able to exert traction on the pleated area. This is on the one hand perceived by the wearer as negative, because by wearing a disposable garment the freedom of movement is anyway somewhat limited. On the other hand, the wearer is in danger of being transferred by the movements in the vicinity of the floor in this way contaminations on the garment, in particular in the upper torso area and / or the waist / hip area of the garment to transfer. In addition, according to given standards with regard to the movement sequences in the surgical area, the wearer of surgical clothing is prohibited from moving, which endangers the sterility, such as movements near the floor, anyway. As a measure of this contamination immediate measure, an assistant could be used to unfold the folded area, but this is disadvantageous in the case of by the wearer on his own garment items or even in emergencies in emergency situations.

It has also been recognized that the zigzag-shaped arrangement of the flat web material and the concomitantly generated sequence of downwardly and upwardly pointing pocket-shaped openings liquids and particles can be accommodated in the openings, but this is not always desirable and should be avoided for hygienic reasons , Thus, a folded portion in a disposable garment, unless, after the garment application operation, this folded portion is not immediately brought to a deployed condition may constitute a contamination trap. In the pocket-like openings facing towards the upper end of the garment, liquids or particles may disadvantageously accumulate during the period of wear, which are then deflated in the event of deployment during the examination and / or operation and thus the hygiene or sterility of the Patient environment can adversely affect. Also, when the disposable garment is removed, the liquids or particles accumulated in the bag-like opening may unexpectedly dislodge and result in contamination of the wearer or the surrounding medical personnel.

Proceeding from this, the object of the present invention is to meet the above-described problems, that is to say, with disposable medical clothing pieces, which are manufactured by a folded manufacturer Area to provide the possibility of extension of the main part to perform special measures regarding the folded area to ensure the requirement for hygiene or sterility, even after a careful or sterile donning the disposable garment. In addition, the donning or wearing a disposable garment for the wearer should be made more comfortable.

This object is achieved according to the invention by a disposable medical garment having the features of claim 1.

Advantageous developments of the disposable medical garment result from the respective subclaims.

In the context of this invention, the "longitudinal direction or carrying direction" refers to the direction taken in the position of use of the disposable item of clothing, namely the direction along the longitudinal axis of an upright carrier of the item of clothing. By "length" is generally understood the extension in the longitudinal direction. The "transverse direction" or "circumferential direction" is the direction perpendicular to the longitudinal direction. The term "upper end" or "lower end" always refers to the arrangement of the garment in the use position on an upright support.

The main body part of the disposable medical garment with the manufacturer-releasably fixed folded portion has a length L1 in the longitudinal direction and is divided longitudinally from the upper end into an upper trunk area, a waist / hip area and a leg area. In the context of this invention, the respective areas are assigned an extension in the longitudinal direction with respect to the length L1 of the item of clothing, namely an extension of 35% to the upper torso area, an extension of 40% to the waist / hip area and an extension of 25% to the leg area.

The folded portion of the flat sheet material is made by folding the flat sheet material from outside to inside. In the context of this invention, the term "uppermost subsection" or "uppermost superposed subsection" means the outermost subsection, that is to say an outer side of the main part. The subsections following inwardly in the fold are understood to be the "lower subsections", in which case the innermost subsection, that is to say an inner side of the main part, is referred to as the "lowermost" or "lowermost" subsection. Starting from a lower subsection, the subsections disposed within the folded region in the direction of the outside are understood to be "upper subsections".

The "uppermost folding edge" is that folding edge which, after the folding of the flat web material in the folded area, is closest to the outside of the main part. Correspondingly, the fold edges following in the fold are the "lower fold edges", in which case the innermost fold edge, that is to say the inside of the main part, is referred to as the "lowest fold edge".

The tubular or kittelförmige main part is always understood as a trouser leg-free body. Kittelförmig refers to a main part, which is not closed in the circumferential direction and on the front or back side free running in the longitudinal or supporting direction edges, which can be brought into overlap in the worn state. On the other hand, a tube-shaped body is at least partially closed in the circumferential direction.

The inventive arrangement and releasable fixation of the folded area in the upper torso area and / or in the waist / hip area of a main part with a length L1 of 80-170 cm, this folded area is at a height along the longitudinal axis of the carrier, within which the carrier itself or even the auxiliary personnel in a well manageable and largely contamination- or sterilization-disturbing zone can bring about the unfolding. In addition, due to the arrangement in the upper torso area and / or in the waist / hip area, the wearer can also apply the pulling force to be carried out in the longitudinal direction for the unfolding of the fixed folded region, since the latter can be applied over the Arm length, which anatomiebedingt usually extends to at least within the waist / hip area, enough leeway to perform a traction force movement in the longitudinal direction, in particular in the direction of the lower end remains. The waist / hip region can be halved with respect to its longitudinal direction by an imaginary line parallel to the transverse direction in an upper first waist / hip portion and in a lower second waist / hip portion.

The folded area is provided in the upper torso area and / or in the upper first waist / hip area. Further preferably, the folded area is provided only in the upper trunk area.

Preferably, the garment is equipped with sleeves. The sleeves may be integrally provided from the flat web material of the main part or may be added as separate components to the main body. In any case, a "transition" from main body to sleeve recognizable. Here, the term "transition" means the area between the longitudinal direction of the main part and the sleeve extending transversely from the longitudinal direction.

In the case of existing sleeves, the folded region is in particular in the longitudinal direction or support direction below a transition between the main part and the sleeves, in particular at a distance from this transition, in particular at least 5 mm, more particularly 10 mm, more particularly 15 mm further in particular not more than 50 mm, more particularly not more than 45 mm, more particularly not more than 40 mm.

Preferably, in the leg region, no folded region extending over the entire transverse or circumferential direction, which is releasably fixed on the manufacturer side, is provided.

Further in the transverse or circumferential direction extending folded areas, which are permanently fixed, may well be provided in the leg area. These further folded regions can advantageously serve in the function of collecting channels for, for example, during the operation occurring quantities of liquid that can run down along the main body, so as to protect the carrier advantageous against liquid ingress into the shoes.

Furthermore, the arrangement of the flat web material according to the invention in the folded region with an uppermost portion which extends up to an uppermost, pointing to the lower end of the main body folding edge, and further deposition of the flat web material in a zigzag shape, the sequence of pocket-shaped openings controlled so advantageous in that the pocket-shaped openings accessible from the outside likewise point in the direction of the lower end. This eliminates the problem that contaminations in the form of liquids or particles in the folded region can accumulate on the body-facing side and thus on the side facing the patient or the environment during wear of the item of clothing.

Due to the zigzag-shaped folding of the flat web material about at least two folding edges arranged transversely to the longitudinal direction, the flat web material has at least three partial sections in the folded region.

In particular, the folded region can be designed in such a way that the flat web material is folded onto itself in a zigzag shape only by two folding edges arranged transversely to the longitudinal direction, forming three sections. But it is also conceivable that the folded region preferably also has flat web material, which is the first zigzag folding, at least by two more transverse to the longitudinal direction, that is folded in the transverse direction lower folding edges to form two further sections folded on itself.

Basically, in the case of folding the flat web material by more than two transverse to the longitudinal direction extending folding edges, the progressive folding of the flat web material is always performed by a number of folding edges, the one Multiple x of two fold edges, ie 2 · x with x ≥ 1. Thus, in addition to the already existing three subsections, a further number of subsections is generated, which successively represents a multiple of 2 subsections, ie 2 · y with y ≥ 1. The folded region preferably has further folded edges with 1 ≦ x ≦ 5, the number of additional partial sections being calculated to be 1 ≦ y ≦ 5.

According to the invention, the disposable item of clothing is provided on the manufacturer side with a fixed folded area, wherein the length of the main part in the longitudinal direction is assigned the length L1 with the still fixed folded area. The folded region can be deployed by applying a tensile force in the longitudinal or support direction, so that the main part after complete unfolding of the folded portion has a length L2, where always L2> L1. The length L1 or length L2 is measured here as the longitudinal extent between the upper and the lower end, wherein the measuring point at the upper end of the neck of the main part existing transition point between the front and back side is used.

The length L1 for the main part with the folded region still fixed is preferably 85-165 cm, more preferably 90-160 cm, more preferably 95-155 cm, further preferably 95-150 cm, further preferably 100-145 cm, further preferably 100. 140 cm, more preferably 100 - 135 cm provided.

After the folded region has been completely unfolded, the main part has a length L2, wherein as length L2 preferably 90-180 cm, more preferably 100-180 cm, further preferably 115-175 cm, further preferably 120-170 cm, further preferably 120 165 cm, more preferably 110 - 165 cm, more preferably 110 - 160 cm are provided.

Advantageously, the ratio of the length L2 to the length L1 (L2 / L1) is at least 1.05, more preferably at least 1.07, more preferably at least 1.1, but preferably at most 1.6, more preferably at most 1.5, more preferably at most 1.4.

The fixed folded portion has a lengthwise extension of the length F1 within the length L1 of the main part. The length F1 of the fixed folded region is limited by the distance from the at least two transverse to the longitudinal direction, ie in the transverse or circumferential direction extending folding edges. In the case where the folded area has more than two fold edges, the fold line facing the upper end and the one closest to this end and the fold line closest to the lower end and closest to this end are used to design the length F1.

Preferably, the folded portion has a length F1 of 5-20 cm, more preferably 5 -15 cm, more preferably 5 -12 cm, further preferably 5 -10 cm.

Furthermore, it is preferably provided that the ratio F1 / L1 of the length F1 of the fixed folded region relative to the length L1 of the main part is at least 0.02, more preferably at least 0.03, more preferably at least 0.04, but preferably at most 0.30 , more preferably at most 0.25, more preferably at most 0.20, further preferably at most 0.15. As a result of this embodiment of the folded region in the longitudinal direction, that is to say its length F1 with respect to the original length L1 of the main part, the folded region extends within a comparatively narrow region, this representing a clearly visible zone, in particular for the carrier itself easier orientation for the points of attack to be applied for the deployment traction is possible.

In a particularly advantageous manner, the ratio L2 / L1 of the length L2 of the main part after complete unfolding of the folded region to the length L1 of the main part with the folded region still fixed, the fixed folded region having a length F1, is at least 1.05, more preferably at least 1.07, more preferably at least 1.1, but preferably at most 1.6, more preferably at most 1.5, even more preferably at most 1.4, and wherein the ratio F1 / L1 is at least 0.02, more preferably at least 0, 03, continue preferably at least 0.04, but preferably at most 0.30, more preferably at most 0.25, more preferably at most 0.20, more preferably at most 0.15. By this configuration of the length F1 of the fixed folded portion with respect to the original length L1 of the main part and in coordination with the lengthening of the main part to be achieved after complete deployment to the length L2, an effective extension can be achieved by means of a well-arranged and thus easily recognizable folded region of the main part can be achieved.

The sections are assigned an extension in the longitudinal direction, each with a length T. The lower sections are each bounded by two fold edges. In the context of this invention, the uppermost and the lowermost subsection are delimited by the uppermost folding edge pointing in the direction of the lower end or the lowermost end edge pointing in the direction of the upper end, and in each case an imaginary transverse line G1 or G2. The line G1 is detected by directing the solder to the flat sheet material constituting the uppermost portion starting from the vertex of the folding end facing the upper end and closest to the upper end of the main body. Analogously, the line G2, starting from the vertex of the folding edge facing the lower end and closest to the lower end, directs the solder onto the flat web material forming the lowermost subsection.

Preferably, the folding of the flat web material within the folded region is such that all formed subsections have the same length T. However, it is also conceivable that in an alternative embodiment of the folding, the sections do not coincide in their length T, but that the sections vary in their lengths T to each other.

In the context of this invention it has also been recognized that folded arrangements, due to the superimposed layers, that is to say the subsections, lead to an areawise thickening of the disposable item of clothing. However, this partial thickening may be perceived as negative by the wearer, particularly the folded area within the upper torso area and / or the waist / hip area, in particular the upper first waist / hip area and / or the lower second waist / hip portion is arranged and if then the folded portion is left at least for the time being in the fixed folded state. It has been recognized that a flat sheet material with a weight per unit area preferably of 10 to 70 g / m ² , more preferably of 20 to 60 g / m ² , particularly preferably of 25 to 50 g / m ² , can advantageously be used for the folded area.

The flat web material forming the folded region and the flat web material, which is provided in the remaining main part of the garment, may have different and / or identical materials. In an advantageous embodiment, the flat web material of the folded region is formed from the same material as the flat web material of the remaining main part of the article of clothing. In an alternative advantageous embodiment, the folded region has a flat web material which differs from the flat web material of the remaining main part.

As a flat sheet material for the folded area, in particular a nonwoven material is used. Particularly preferably, the flat web material of the folded region is formed as a laminate of a sequence of spunbond (S) and / or meltblown (M) layers, in particular as a laminate of spunbond (S) and meltblown (M) layers, in particular with a spunbond layer as an outer layer, particularly preferably formed as SM, SMS, SMMS, SMMMS. The material may have different properties, depending on whether and, if appropriate, in which combination in a laminate spunbond or meltblown layers are included. Particularly preferably, the nonwoven material consists of polyethylene and / or polypropylene and / or mixtures thereof as the main component. The folded region has, as a flat sheet material, in particular a nonwoven material made of polypropylene, preferably with a weight per unit area of 10 to 70 g / m ² , more preferably 20 to 60 g / m ² , particularly preferably 25 to 50 g / m ² .

The folded area is according to the invention releasably fixed by the manufacturer. By "releasably fixed" is meant that under the action of a force, in particular a tensile force in the direction of the longitudinal or supporting direction, the fixation of the folded Area, in particular without destruction of the flat web material, can be resolved.

In an advantageous manner, the folded region is removed by means of holding elements from the group of ultrasonic welding points, thermal welding points, calender welding points, adhesive sites, adhesive elements, in particular single- or double-sided adhesive tapes, mechanical elements, in particular hook / loop elements, adhesive lines equipped with break lines and / or or mechanical elements, binding tapes or combinations thereof, releasably fixed. The hook / loop elements are also referred to as Velcro hook / Velcro elements or hook / loop elements.

It is particularly preferably provided that the holding elements are arranged at least partially within the longitudinal extent of at least one section. Further preferably, the holding elements are arranged at least partially within their longitudinal extent in all subsections.

Further preferably, the holding elements are provided such that they are arranged exclusively within the longitudinal extension of the at least one section, in particular within the longitudinal extension of all sections and act as joints in it.

Preferably, the retaining elements can also be designed such that they are arranged within the longitudinal extent of at least one section and extend beyond at least one of the upper end of the main part facing folding edge.

For releasably fixing the folded area, combinations of retaining elements which are arranged exclusively within the longitudinal extension of the subsection and in which the joints are and holding elements which extend beyond at least one folding edge facing the upper end are also conceivable.

In principle, the arrangement of the holding elements within the longitudinal extent of a subsection is advantageous since this achieves better stabilization of the subsection within the folded region.

Preferably, the holding elements may be introduced into the folded region in such a way that the holding elements releasably connect the respectively directly adjacent subsections with one another. The holding elements can be introduced in each case between two directly adjacent sections. This is conceivable in particular for holding elements in the form of adhesive sites and / or double-sided adhesive tapes and / or hook / loop elements. In each case directly adjacent sections can also be advantageously connected by means of ultrasonic welding and / or thermal welding and / or calender welds releasably.

Particularly preferably, a plurality of adjacent subsections, in particular all subsections, can be detachably connected to one another by a method step. This embodiment is conceivable in particular for holding elements in the form of ultrasonic welding points and / or thermal welding points and / or calender welding points.

The holding elements are preferably arranged all along the longitudinal direction at the same height. This is depending on the choice of the holding element a technically easy to perform and thus time and often also material and thus cost-saving embodiment. In particular, the holding elements in the form of ultrasound and / or thermal and / or calender welding points are all preferably arranged at the same height. However, it is also conceivable that the holding elements are arranged along the longitudinal direction at different heights.

In particular, preferably, the holding elements are arranged within at least one of the subsections at a distance H to the respective folding edge. Preferably, the holding elements are arranged within all sections at a distance H to the respective folding edges. The distance H is measured in each case over the distance between the extending in the transverse or circumferential direction edge of the holding element and the adjacent folding edge. It was recognized that the arrangement of the holding elements at a distance from the respective folding edges advantageous in the process of unfolding the folded area, since the tensile force acting in the longitudinal direction or more effectively transferred to the holding elements and thus the dissolution of the fixation can be performed easily ,

In particular, preferably, the holding elements are arranged at a distance H within at least one of the subsections, the distance H being at least 3%, preferably at least 5%, more preferably at least 7%, more preferably at least 10%, based on the length T of the at least one respective subsection is. Preferably, the holding elements are arranged in all sections with a distance H of at least 3%, preferably at least 5%, more preferably at least 7%, more preferably at least 10% based on the length T of the respective section.

Further preferably, the holding elements are arranged exclusively within the longitudinal extension of the at least one section with a distance H and act as joints. Further preferably, the holding elements are arranged at all subsections exclusively within the longitudinal extension of the sections at a distance H and act as joints.

The holding elements have a longitudinal extent S within the longitudinal extent of the at least one partial section. In particular, it is provided that the longitudinal extension S of the holding elements and the length T of the subsection are matched to one another. In particular, the holding element preferably assumes a longitudinal extension S within the at least one subsection, such that the ratio of S to the length of the at least one respective subsection is at least 0.02, preferably at least 0.03, more preferably at least 0.04, but preferably at most 0 , 25, more preferably at most 0.20, more preferably at most 0.15. By means of this proportion of the longitudinal extent S of the holding element within the length T of the respective subsection, a sufficient fixation of the subsection and its stabilization in the folded section can be achieved Range could be achieved without setting a too large fixing zone in the longitudinal direction, which would otherwise disadvantageously a greater force for the deployment of the folded area and also a larger attack surface within which the flat web material could be subjected to destruction upon application of the tensile force. By an optimized ratio of the longitudinal extent S of the holding element to the length T of the section also an excessive use of holding elements and the material required therefor and thus costs can be avoided.

The longitudinal extent S of the holding elements is preferably from 0.5 to 3.0 cm, more preferably from 0.5 to 2.5 cm, more preferably from 0.5 to 2.0 cm.

In particular, the holding elements are arranged within the longitudinal extent of at least one partial section, preferably within the longitudinal extension of all partial sections in the form of a strip. In particular, preferably, the holding elements are arranged as strips in the circumferential direction continuously, ie continuously and without intervals.

Preferably, the holding elements, which are arranged exclusively within the longitudinal extension of the section and act as joints in the form of strips in the form of ultrasonic welding and / or thermal welding and / or Kalanderschweißstellen and / or adhesive sites formed. In particular, the strip is provided as a circumferentially continuous weld seam.

Alternatively, the arrangement of the holding elements can be provided within the longitudinal extent of at least one subsection, preferably within the longitudinal extension of all subsections, also in the form of strips spaced in the circumferential or transverse direction.

It is provided in particular that the spaced-apart strips are arranged at the same height along the longitudinal axis.

Further preferably, the ratio of the longitudinal extent to the transverse extent is at least 0.02, more preferably at least 0.05, further preferably at least 0.1, but preferably at most 0.9, more preferably at most 0.8, further preferably at most 0.7.

The distance between the strips is preferably chosen so that the zigzag folding of the sections can not begin to gape apart. The distance between the spaced strips is preferably 5 to 20 cm, more preferably 7 to 15 cm, more preferably 7 to 12 cm.

In particular, the holding elements in the form of spaced strips, which are arranged exclusively within the longitudinal extension of the section and act as joints, preferably in the form of ultrasonic welding and / or thermal welding and / or Kalanderschweißstellen and / or adhesive sites formed.

As already stated above, the retaining elements can be arranged within the longitudinal extent of at least one section and extend beyond a folding edge pointing towards the upper end of the main part. In continuation of this embodiment may be provided in particular that the holding elements, starting from the inside of a lower section and thereby at least one lower folding edge and at least one facing the upper end pocket-like opening on the inside of an upper, in particular a lower portion directly adjacent upper Partial section and / or on the inside of the folding web material outside the folded area are releasably fixed.

Preferably, the holding elements, which are arranged within the longitudinal extension of at least one section and extend beyond a pointing to the upper end of the main part folding edge and thus act as joints, as strips in the form of adhesive elements, in particular one or double-sided adhesive tapes formed.

In the case of holding elements which extend beyond a folding edge pointing toward the upper end of the main part, provision is made in particular for these holding elements to be arranged within the partial section in a folding edge edge region adjoining the folding edge with the longitudinal extent O and fixed therein.

Preferably, the holding elements are arranged within a subsection in a folding edge edge region adjoining the folding edge with a longitudinal extent O and determined that the ratio of the longitudinal extent O of the folded edge edge region to the length of the respective subsection is at least 0.02, preferably at least 0.03, more preferably at least 0 , 04, but preferably at most 0.25, more preferably at most 0.20, more preferably at most 0.15.

By this proportion of the longitudinal extent O of the folded edge edge region, in which the holding elements are arranged and fixed, with respect to the length T of the respective section, a sufficient fixation of the section and its stabilization in the folded region can be achieved without setting a too large fixing zone in the longitudinal direction which would otherwise be disadvantageously a greater force for the deployment of the folded area and also a larger attack surface within which the flat web material could be subjected to destruction upon application of the tensile force. By an optimized ratio of O to T also an excessive use of holding elements and the required material and thus costs can be avoided.

For this embodiment, with holding elements which extend beyond a folding edge pointing towards the upper end of the main part, holding elements in the form of a strip with a longitudinal extension and in particular are provided Transverse extension provided. Further preferably, the holding elements, which point toward the upper end of the main part and bridge over the folded edge, are arranged essentially centrally in their longitudinal extent. "Essentially central arrangement" means a deviation of at most 10%, more particularly of at most 5% of the longitudinal extent, ie with an arrangement of the holding elements closer to the upper end or closer to the lower end of the garment.

In particular, these strips are arranged as circumferentially spaced strips, wherein the spaced strips are arranged in particular at the same height along the longitudinal axis.

The dimensions of the spaced strips are preferably chosen such that the transverse extent is greater than the longitudinal extent. Further preferably, the ratio of the longitudinal extent to the transverse extent is at least 0.1, more preferably at least 0.2, more preferably at least 0.3, but preferably at most 0.9, more preferably at most 0.8, further preferably at most 0.7.

Particularly advantageously, the dimensions of the spaced strips are selected so that the longitudinal extent is greater than the transverse extent. Further preferably, the ratio of the longitudinal extent to the transverse extent is at least 1.5, more preferably at least 1.7, more preferably at least 1.9, further preferably at most 3.0, more preferably at most 2.8, further preferably at most 2.6.

The longitudinal extent refers to the extension, which has the strip in the longitudinal direction or support direction.

The transverse extent refers to the extension, which has the strip in the transverse direction or circumferential direction.

The distance is preferably chosen so that the zigzag folding of the sections can not begin to gape apart. The stripes are in a distance of preferably 5 to 25 cm, more preferably 5 to 20 cm, more preferably 7 to 15 cm, further preferably 7 to 12 cm.

In the case of the arrangement of the folded region in a region which is not closed in the transverse or circumferential direction, the holding elements are arranged at such a distance from the free side edges of the main part, that the folded region, so the zigzag folding of the sections, not apart gape can begin. The holding elements are in such case at a distance from the free side edges of preferably at most 10 cm, more preferably at most 7 cm, more preferably at most 5 cm, further preferably at most 2.5 cm. Preferably, the holding elements are spaced from the free side edges of the main part, preferably at a distance of at least 0.25 cm, more preferably at least 0.5 cm, more preferably at least 1.0 cm. This advantageously ensures that the free side edges arranged nearest holding element does not overhang from the side edges and thus protruding, thus causing an unwanted fixation of the retaining element to other areas of the main body.

In particular, preferably, the holding element are not uniformly spaced from each other. Preferably, the holding elements in a region of the disposable medical garment, which in use, ie in the wearing state of the garment may be exposed to a greater force, such as in particular on the front of the garment, a smaller distance from each other as holding elements, which exposed in the wearing state less strong forces be, especially on the back side of the garment.

In particular, the holding elements, which extend beyond a folding edge pointing to the upper end of the main part, are preferably in the form of single-sided adhesive tapes. The strips preferably have a longitudinal extent P of 1.0-5.0, more preferably 1.0-4.0, more preferably 1.0-3.0 cm, further preferably 1.0-2.5 cm preferably from 1.0 to 2.0 cm, and having a transverse extent R of preferably 1.0 to 5.0 cm, more preferably 1.0 to 4.0 cm, more preferably 1.0 to 3.0 cm, more preferably from 1.0 to 2.5 cm, more preferably from 1.0 to 2.0 cm, more preferably formed from 1.0 to 1.5 cm.

The one-sided adhesive tapes are fixed with their adhesive upper side on the partial section or the flat web material.

Preferably, the single-sided adhesive tapes comprise a carrier material of a polymer, in particular of polyethylene, polypropylene, and / or polyethylene vinyl acetate or mixtures, which is provided on an upper side with an adhesive coating, in particular a polyacrylate adhesive. Further advantageously, the adhesive tape is provided with a carrier material which is easily rupturable in the longitudinal and transverse directions, which is provided in particular with perforations as predetermined breaking points.

In a further development of the concept of the invention, the materials of the holding means and the flat web materials of the main part or the folded region of the disposable medical garment are matched to one another such that the unfolding of the folded region requires a defined tensile force, measured as described below.

This ensures that, during use of the disposable item of clothing, the folded area is intentionally dissolved with the corresponding application of force, but otherwise the folded area is retained and does not open unintentionally.

In a particularly advantageous embodiment of the present invention, the unfolding of the folded region requires a tensile force of at least 5 N / 50 mm, in particular at least 7 N / 50 mm, in particular at least 10 N / 50 mm, more particularly at least 12 N / 50 mm, more particularly at least 15 N / 50 mm. Advantageously, however, the required tensile force is less than 30 N / 50 mm, in particular less than 25 N / 50 mm, more particularly less than 22 N / 50 mm, in particular less than 20N / 50mm, more particularly less 18 N / 50mm.

Traction test:

The following is a test method for determining the tensile force of the manufacturer releasably fixed folded area specified.

For the performance of the test method, a tensile tester of accuracy class 1, such as a tensile tester type Z010 / TN 2S, load cell 100 N, or type Z005, load cell 100N, each available from Zwick GmbH & Co KG, Ulm, Germany, with a Jaw width can be used for clamping the test piece of 60 mm.

Sample preparation:

Test specimens of size 50 x 250 mm (width B x length L) are punched out (the width in the transverse direction and length in the longitudinal direction of the item of clothing being understood) in such a way that the folded area and the holding element at least in the longitudinal direction considered, completely and undamaged within the size, ie the length of the specimen are included. For holding elements with a transverse extent greater than 50 mm, the test piece is also selected with a width of 50 mm and the holding element accordingly cut along its longitudinal direction during punching. In the case of several holding elements within the width of the specimen of 50 mm as many adjacent juxtaposed holding elements are detected with their complete transverse extent and optionally holding elements which fall with their transverse extent outside the width of the specimen cut in its longitudinal direction during punching.

In this case, the width B of the test piece is its extension in the transverse direction and the length L its extension in the longitudinal direction of the item of clothing.

The samples to be used are conditioned for 24 h at 23 ° C and 50% relative humidity.

Test method:

• Prüfgeschwindigkeit: 400 mm/min
• Einspannlänge des Prüflings: 200 mm
• Messweg: Strecke bis zur der ersten maximalen Kraftspitze
• Vorkraft: 0,1 N
• Prüfanzahl: n mindestens 5

The test parameters are:

• Test speed: 400 mm / min
• Clamping length of the specimen: 200 mm
• Measuring distance: Distance up to the first maximum force peak
• Pre-load: 0.1 N
• Test number: n at least 5

The implementation will be based on the FIG. 10 described.

The test piece 100 with its width B = 50 mm is clamped at one end into the lower jaw 104 and at the other end in the upper jaw 102 of a normalized tensile testing machine, wherein the folded portion 20 and the holding member 40 across the flat web material of the main part can not be fixed by the clamp receptacles 102, 104. The specimens are centered in their longitudinal extent centered as possible clamped in the jaws.

The distance 106 of the facing edges of the jaws is 200 mm (ie the clamping length). The jaws are then moved apart at a test speed V of 400 mm / min in the plane of their extension and thereby the tensile force acting in this direction is measured. The tensile force is understood to be the maximum force at which the fixation of the folded region which can be released by the manufacturer is released and the folded region can unfold. In particular, five individual measurements are made and their mean value is calculated.

The evaluation is carried out in such a way that the maximum force determined up to the dissolution of the folded area is rounded down to two decimal places in N (Newton) and in the form of an average of the n measurements (and indication of the Standard deviation and a minimum value and a maximum value) in relation to the sample width 50 mm.

In particular, preferably, a holding element is selected, which extends beyond the longitudinal extent of a subsection over at least one folding edge of the subsection facing the upper end and is releasably secured on the inside of the flat web material outside the folded area, in the embodiment of a single-sided adhesive tape with a polyacrylate adhesive as adhesive Coating, more particularly with a longitudinal extent of 1.0 - 3.0 cm and a transverse extension of 1.0 - 2.0 cm. The tensile force for unfolding the folded portion is preferably 7 N / 50 mm - 18 N / 50 mm.

In the disposable garment, preferably, further, a belt means for regulating the width of the body in the circumferential direction may be provided. The belt device is preferably arranged outside the folded region. In this case, the belt device is in particular above the folded region, i. arranged on the side facing the upper end, i. the distance of the belt means to the upper end is smaller than the distance of the folded portion to the upper end. This is advantageous because the unfolding of the folded region does not result in any displacement of the belt element along the longitudinal axis of a carrier. Thus, even with a downstream deployment of the area, there is no need to re-adapt the width of the main part. Otherwise, the belt device may be advantageously below the folded area, i. be arranged on the side facing the lower end. This is particularly advantageous if the folded region is provided in the upper body region.

In particular, the belt device is at a distance of at least 0.5 cm, more preferably at least 1.0 cm, more preferably at least 1.5 cm to the folded region, but preferably at a distance of at most 5.0 cm, more preferably from not more than 4.5 cm, more preferably arranged by the highest 4.0 cm.

In this case, it is particularly preferred if the belt device is already closed by the manufacturer on the factory side, so that no complicated closure of the belt device by the wearer of the item of clothing has to be made anymore. In this case, in particular closure elements, for example in the form of buckles, but also two-D rings, through which a band element is pulled through and wherein the two D-rings are connected to a further band element may be provided. Particularly preferred is a belt means for adjusting the circumference of the main part to a body circumference, wherein the belt means comprises a first band, which is connected to the main part and having a first free end of the tape, and wherein the belt means comprises a second band, which with the main part is connected and has a second free end of the tape, wherein in a factory offered initial state of the garment, the first band and the second band are entwined in a Verschlingungsbereich with each other such that by pulling on the first free end of the tape and the second free end of the tape in opposite directions Scope of the main part and thus the garment is continuously reduced in size. By simply pulling on the free ends of the belt, the belt means can be reduced in circumference so as to reduce the circumference of the body and thus of the garment until it conforms to the body circumference of the wearer, e.g. a surgeon. In particular, it is not necessary for the wearer himself or the auxiliary personnel, for example a nurse, to knot the free ends of the band together after putting on the item of clothing. Thus, the garment according to the invention can be tightened quickly and without assistance staff.

Such a manufacturer-prefabricated closed belt device is provided in particular for garments with a tubular main part.

For the belt device also closure bands can serve in the conventional manner. It can be provided that a binding tape is attached to the back side of the main part, in particular in the waist / hip area, in particular on the side edge of a back part and another binding band on the Front side of the main part, in particular in the waist / hip area is attached, and wherein both binding tapes manufacturer on a transfer card are defined, from which the bands can then be removed when putting on the garment, so that a second person then helps the garment wearer when donning by holding the straps and the carrying person turns around his own axis.

FIG. 1a shows a disposable medical garment, which is provided in its entirety by the reference numeral 2, looking at the front side. The garment 2 has a main part 8, which may be coat or kittelförmig formed. The item of clothing 2 also has sleeves 7, which are bound to the main part 8. The main part 8 extends in the longitudinal or supporting direction 4 between an upper end 10 and a lower end 12, and has over the entire transverse or circumferential direction 6 extending folded portion 20, wherein the configuration of the folded portion 20 based on Section plane A - A in the FIG. 2 will be shown in more detail. The garment 2 is provided by the manufacturer with the folded portion 20, wherein the main part 8 extends in the state presented in the manufacturer side in the longitudinal direction 4 over the length L1. The main part 8 is divided from the upper end 10 in the longitudinal direction 4 into an upper torso area 26, a waist / hip area 28 and a leg area 30. Here, the trunk area 26 extends over 35%, the waist / hip area 28 over 40% and the leg area 30 over 25% of the length L1. The folded portion 20 is disposed in the waist / hip portion 28 and is formed by the folding of the flat sheet material 18 having the main portion 8.

The folded region 20 is according to FIG. 2 according to the sectional view AA from the FIG. 1 a is formed as follows. The folded part 20 has the flat web material 18 in the form of partial sections 18a, 18b, 18c, which at least two transverse to the longitudinal direction 4 extending fold edges 22, 24 zigzag-shaped , ie in the form of a Z, are folded onto themselves. The part of the subsections uppermost resting portion 18a, so that portion which forms an outer side 16 of the main part 8, extending in the longitudinal direction 4 to an uppermost folding edge 22, wherein an uppermost folding edge of the outer side 16 closest folding edge is understood. As a result of the zigzag folding follows the flat web material 18 in a lower portion 18b to turn on a lower fold edge 24 to then be continued as the bottom portion 18c. Due to the zigzag folding sequence of the sections 18a, 18b, 18c become corresponding pocket-shaped openings 32, 33 conditionally, wherein the accessible from the outside 16 opening 32 points exclusively in the direction of the lower end 12. The folded region 20 extends in the longitudinal direction 4 of the main part over the length F1. The length F1 of the folded region 20 is limited by the distance from the at least two folding edges 22, 24 extending transversely to the longitudinal direction 4, ie in the transverse or circumferential direction 6. In the case where the folded portion 20 has more than two fold edges, for dimensioning the length F1, as shown schematically in FIG FIG. 3 shown and explained in more detail later, the nearer to the upper end 10 and the upper end 10 closest and the lower end 12 facing and the lower end 12 closest fold edge zoom. The in the folded area 20 of FIG. 2 existing subsections 18a, 18b, 18c extend in the longitudinal direction 4 each with a length T. The lower portion 18b with the length T 18b is limited by the two folded edges 22, 24. The uppermost partial section 18a or the lowermost partial section 18c are bounded by the uppermost folding edge 22 or the lowermost folding edge 24 and in each case by an imaginary line G1 or G2 extending in the transverse direction 6. This line G1 or G2 is determined by starting from the vertex of the top edge 10 of the main part 8 closest fold edge 24 and the lower end 12 of the main part 8 closest fold edge 22, the Lot on the top portion 18a forming flat web material or on the lowermost portion 18c forming flat sheet material is directed. In a preferred embodiment according to FIG. 2 with a folded region 20 consisting of three sections 18a, 18b, 18c, which are folded back in a zigzag shape about itself in the transverse direction 6 folding edges 22, 24, the length F1 of the folded portion 20 and the lengths of the sections T 18a, T vote 18b, T 18c match. The folded region 20 is releasably fixed by the manufacturer (not shown in this figure). By the action of a tensile force K in the longitudinal or supporting direction 4, the disposable garment 2 in the in FIG. 1b transferred state shown schematically. Upon completion of unfolding of the folded region, with the original fold edges 22, 24 being released, the body portion 8 of the garment 2 then extends longitudinally between the upper end 10 and the lower end 12 with a length L2, where L2> L1.

Figure 1c schematically shows the arrangement of the folded portion 20 with an upper folding edge 22 and a lower folding edge 24 in the upper body portion 26. Within the support or longitudinal direction 4 in the manufacturer still releasably fixed state of the folded portion with a length L1 of the garment 2 is the waist / Hip area as an upper first waist / hip portion 28a and as a lower second waist / hip portion 28b divided, the latter then merges into the leg portion 30. The disposable garment 2 has sleeves 7 attached to the main body 8. The folded region 20 is arranged at a distance A in the longitudinal direction, viewed below the transition 9 from the main part 8 to the sleeve 7, at a distance A of preferably 15-35 mm. FIG. 1 d shows schematically the item of clothing 2 with the length L2, that is, with the folded area in the unfolded state, the previous folding edges 22, 24 being indicated.

The folded region 20 may be formed of a flat sheet material 18 which is folded in a zigzag fashion over itself by forming more than two transverse fold edges in a zigzag fashion to form subsections. FIG. 3 shows an embodiment of a folded portion, wherein the flat web material 18 by four fold edges (22, 24, 220, 240) to form five sections (18a, 18b, 18c, 18d, 18e) folded back zigzag on itself. The two folding edges 24, 240 facing the upper end 10 and the two folding edges 22, 220 facing the lower end 12 are arranged at different heights along the longitudinal direction 4. The folded region 20 extends with the length F1 between the fold end 24 closest to the upper end 10 and the fold edge 220 closest to the lower end 12. These two fold edges arranged furthest along the longitudinal direction 4 are also used to determine the Length T of the uppermost portion 18a and the lowest portion 18e used. For this determination, starting from the vertex of the upper end 10 of the flat web material 18 facing and the upper end 10 nearest fold edge 24 and the lower end 12 of the flat web material 18 facing and the lower end 10 nearest fold edge 220, the solder on the the top one Parting section 18a or directed to the lowermost portion 18e forming flat sheet material. The respective lengths T of the individual subsections (18a-18e) result at the lower subsections (18b, 18c, 18d) from the extension between the respective folded edges (22-24, 24-220, 220-240) and at the uppermost subsection 18a and the lowermost portion 18e from the extension between the respective fold edge 22, 240 and the respective line G1, G2.

The folded area is introduced in the disposable garment manufacturer releasably fixed. For the releasable fixation holding elements, which in particular in the form of ultrasonic welding, thermal welding, calender welding, adhesive sites, adhesive elements, in particular single- or double-sided adhesive tapes, mechanical elements, in particular hook / loop elements, equipped with predetermined breaking lines adhesive and / or mechanical Elements, ties or combinations thereof are formed, are used.

Preferably, the retaining element is arranged at least partially within the longitudinal extent of at least one section. The FIGS. 4a and 4b schematically show a folded portion 20, wherein the holding member 40, 40 'in all of the flat web material 18 formed portions 18a, 18b, 18c within its length T 18a, T 18b, T 18c is arranged. The holding elements 40a, 40a 'detachably connect the respectively directly adjacent sections with each other. So are in the execution after Fig. 4a the subsections 18a and 18b are connected by means of retaining element 40a and the subsections 18b and 18c by means of retaining element 40a '. The holding elements 40a, 40a 'can be mounted in the longitudinal direction at different heights. Also, the holding elements 40a, 40a 'may differ in their material composition. Preferably, the directly adjacent subsections releasably interconnecting holding elements 40a at the same height along the longitudinal direction 6, such as FIG. 4b shows, arranged. This version after FIG. 4b is particularly advantageous for holding elements 40a in the form of ultrasonic and / or thermal and / or calender welding, since this type of holding elements by means of only a single Process step can be introduced at the same height along the longitudinal direction. Advantageously, the holding elements 40a, 40a 'within the respective section with a distance H to the respective folding edges 22, 24 are arranged. A distance H to the folded edges is advantageous since, when a tensile force acts in the longitudinal direction, the folded area provided by the manufacturer can thus be unfolded completely more easily. The distance H is determined between the folding edge and the adjacent transverse edge of the holding element. The distance H is advantageously at least 3%, preferably at least 5%, more preferably at least 7%, more preferably at least 10%, based on the length of the respective section T18a, T18b, T18c.
