[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disposable surgical drape for exposing only a surgical site of a patient and covering other parts during surgery.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, during operation, a surgical drape has been used to have an opening for exposing only a surgical site of a patient and to cover other portions. This surgical drape is used for the purpose of maintaining the patient in a clean state, maintaining the patient's body temperature, and preventing the patient's blood and chemicals from being scattered. Examples of the surgical drape include cotton cloth, non-woven cloth, and cotton cloth or non-woven cloth subjected to water repellent finish.
[0003]
The function required for the surgical drape differs depending on the type of surgery. For example, in the case of surgery that produces a large amount of liquid, such as caesarean section, it is necessary that the liquid absorbency is high near the opening of the surgical drape, but other parts are splashed with blood or chemicals and other parts Is present to prevent soiling, where high absorbency is not required. Conversely, depending on the type of surgery, high water repellency is desired in the vicinity of the opening, and some degree of absorbency may be desired in other locations.
[0004]
[Problems to be solved by the invention]
However, conventional surgical drapes are made of a single piece of cotton or non-woven fabric, and if it is attempted to increase liquid absorbency or increase water repellency in all areas, the cost, thickness, Hardness increases and it becomes difficult to use. In addition, if a plurality of surgical drapes having different functions are used, installation takes time and a gap is generated between the drapes, which causes a problem in terms of maintaining a clean state.
[0005]
In addition, when a plurality of sheets having different functions are joined to form a surgical drape, blood or a drug solution permeates through joints between edges of the plurality of sheets, and the blood passes from the joints to the floor surface below the joints. Or chemicals may penetrate.
[0006]
The present invention solves the above-described conventional problems, and an object thereof is to provide a surgical drape having partially different liquid absorbency or water repellency.
[0007]
Another object of the present invention is to provide a surgical drape capable of preventing the penetration of blood and chemicals from the joint between the sheets to the floor surface when joining sheets having different liquid absorbency or water repellency. Yes.
[0008]
[Means for Solving the Problems]
The present invention is a drape having a surface layer formed of a nonwoven fabric and provided with an opening or a U-shaped end for exposing a surgical site,
Edges of a plurality of sheets having surface layers with different liquid absorbability or water repellency are joined together, and the surface layer in the peripheral region of the opening or the U-shaped end is a region other than the peripheral region compared to the surface layer, a liquid-absorbent or water repellency are high Kuna',
At the joint between the sheets, the edge of one sheet is folded back so that the back surface faces upward, and is joined to the surface of the one sheet, and the back surface of the other sheet is turned upward of the folded edge It is bonded on the back surface .
[0009]
The surgical drape of the present invention is partially different in liquid absorbency or water repellency. Therefore, a single surgical drape can be used in various operations. The absorption of blood and chemicals has been improved because the surface layer has improved liquid absorbency or water repellency, especially in the periphery of the opening for exposing the surgical site or the end of the U-shaped end, that is, in the region where the outflow of blood or chemicals is large. And water repellent function. Further, by reducing the liquid absorbency or water repellency in other regions, a surgical drape can be produced at a low cost.
[0011]
When a plurality of sheets are joined, sheets having different liquid absorbency or water repellency can be cut separately and used. Further, it is not necessary to cut one drape having a large area from the sheet, and the production is easy.
[0012]
In addition, the other sheet extends from the folded edge to the surface of the one sheet, and the back surface of the other sheet that extends is joined to the surface of the one sheet. preferable.
[0013]
In this way, the edge of one sheet is folded, and the folded edge and the edge of the other sheet are joined to each other by the back surfaces, so that blood and chemicals flowing on the one sheet can be folded. This prevents the blood and the chemical solution from flowing out from the joint between the sheets to the floor surface.
[0014]
Moreover, it is preferable that the edge part of said one sheet | seat is return | folded in the direction away from the said opening part or the said U-shaped edge part.
[0015]
In this configuration, when blood or chemicals flowing toward the periphery from the opening or the U-shaped end for exposing the surgical site travels to the sheet in the peripheral region, the junction between the sheets is overcome according to the flow of blood or the like. As a result, it is possible to effectively prevent the leaching of blood or the like from the joint portion between the sheets to the back surface side.
[0016]
The surgical drape of the present invention has a three-layer structure in which a liquid-impermeable layer is sandwiched between the surface layer formed of a nonwoven fabric and a back layer formed of the nonwoven fabric. Can do.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the surgical drape of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the surgical drape of the present invention. 2A is a cross-sectional view illustrating the joining state of the sheets, FIG. 2B is a cross-sectional view taken along the line II-II in FIGS. 1 and 3, and FIG. 3 illustrates a state in which the joined sheets are further joined together. It is a perspective view shown.
[0018]
As shown in FIG. 1, the surgical drape 1 of the present invention is formed by joining a plurality of sheets 11, 12, 13, 14, 15, 16, 17, 18, and 19. This surgical drape 1A is a rectangle having a side of about 1 to 4 m. At the center of the surgical drape 1A, an opening 2 for exposing the surgical site of the patient is provided. For this reason, locations other than the surgical site of the patient are covered with the surgical drape 1A. When the surgical drape 1A is used for surgery on the legs and arms, the opening 2 is provided with a stretchable film. When the patient's legs and arms are passed through the opening 2, the film is applied to the legs and arms. May adhere so that no gap is formed between the patient's skin and the opening 2 as a result.
[0019]
The sheets constituting the surgical drape 1A have different liquid absorbability. First, the sheet 11 located in the center of the surgical drape 1A and provided with the opening 2 has the highest liquid absorbability compared to other sheets. The sheets 12, 13, 14, and 15 that are continuous in the upper, lower, left, and right sides of the sheet 11 have lower liquid absorbency than the sheet 11 and higher liquid absorbency than the remaining sheets 16, 17, 18, and 19. That is, the vicinity of the opening 2 has the highest liquid absorbency, and the liquid absorbency decreases as the distance from the opening 2 increases. In use, the liquid can be sufficiently absorbed in the vicinity of the opening 2 where a large amount of liquid is generated. And in the location away from the opening part 2, even if the liquid absorptivity is low, it can be sufficiently captured if it is a small amount of droplets.
[0020]
As can be seen from the cross-sectional views of FIGS. 2A and 2B, each sheet has a three-layer structure in which both surfaces of the liquid-impermeable intermediate layer 6 are sandwiched between the surface layer 5 and the back surface layer 7. Each layer is bonded to each other with a hot melt adhesive or the like.
[0021]
The surface layer 5 directed to the outside is a non-woven fabric formed of fibers subjected to hydrophilicity or hydrophilization treatment, for example, a spunlace nonwoven fabric, a thermal bond nonwoven fabric, a point bond nonwoven fabric, a spunbond nonwoven fabric, or an air-through nonwoven fabric. is there. As a preferable specific configuration of the nonwoven fabric, the basis weight is 20 to 100 g / m ² , more preferably 35 to 55 g / m ² .
[0022]
It is preferable to form the back surface layer 7 directed to the patient side with a nonwoven fabric or a woven fabric because the liquid on the patient side can also be absorbed. However, the nonwoven fabric is preferable because it is cheaper. Examples of the nonwoven fabric include spunlace nonwoven fabric, thermal bond nonwoven fabric, point bond nonwoven fabric, spunbond nonwoven fabric, and air-through nonwoven fabric. As a preferable specific configuration of the nonwoven fabric, the basis weight is 15 to 100 g / m ² , more preferably 15 to 30 g / m ² .
[0023]
The intermediate layer 6 sandwiched between the front surface layer 5 and the back surface layer 7 is preferably composed of a liquid-impermeable material. If the intermediate layer 6 is liquid-impermeable, moisture, dirt, and bacteria are not passed to the back layer 7 side, and the patient is not contaminated. Examples of the liquid-impermeable material include a flexible film such as a polyolefin-based polyethylene (PE) film, a copolymer film, and a breathable film. Synthetic rubber and natural rubber sheets can also be used. Among these, a polyethylene sheet having a thickness of 15 to 70 μm, more preferably 18 to 30 μm is preferable.
[0024]
However, the surgical drape of the present invention may be formed with only the surface layer 5 and with only the surface layer 5 and the intermediate layer 6. Further, the sheets may have different layer structures. For example, only the central sheet 11 may have the three-layer structure, and the other sheets may have a one-layer or two-layer structure. In addition, a surgical drape may be formed using a sheet having a multilayer structure in which another sheet is laminated on the three-layer structure.
[0025]
Each sheet is bonded so that the outer liquid (located on the surface layer 5) does not leak to the patient side. 2A and 2B show a joining structure of the sheet 11 and the sheet 13. First, as shown in FIG. 2 (A), the edges 11e and 13e between adjacent sheets 11 and 13 are bent upward in the figure in the Z direction, and the edges 11e and 13e The back surface layers 7 of both sheets 11 and 13 are joined together. At this time, the back surface of the sheet 11 and the sheet 13 is set such that the bending dimension (width dimension of the end) 13w of the edge 13e of one sheet 13 is shorter than the bending dimension 11w of the edge 11e of the other sheet 11. The layers 7 are joined with an adhesive.
[0026]
Then, as shown in FIG. 2B, the edge portion 11e and the edge portion 13e where the back surfaces are joined are brought down on the surface layer 5 of one sheet 13, and the surface layer of the edge portion 13e turned back. 5e is joined to the surface layer 5 of the sheet 13 with an adhesive. The edge portion 11e of the other sheet 11 extends from the edge portion 13e of the one sheet 13, and the back layer 7e of the extending edge portion 11e gets over the folded edge portion 13e, The sheet 13 is bonded to the surface layer 5 with an adhesive.
[0027]
That is, as shown in FIG. 2 (B), at the joint between the sheet 11 and the sheet 13, the edge 13e of one sheet 13 is folded in two so that the back surface faces upward. The surface layers 5 and 5e of the sheet 13 are joined to each other. Further, the back surface layer 7e at the edge portion 11e of the other sheet 11 is joined to the back surface layer of the edge portion 13e that is folded back and climbs over the edge portion 13e onto the surface layer 5 of the one sheet 13. The back surface layer 7e of the other sheet 11 and the surface layer 5 of the one sheet 13 are joined to each other.
[0028]
In this joining structure, the liquid flowing on the surface of the sheet 13 is blocked by the edge portion 11e and does not reach the joining portion between the back surface of the edge portion 13e and the back surface of the edge portion 11e. Further, since the liquid flowing on the surface 1 s of the sheet 11 passes over the joint portion between the sheets and reaches the surface layer of the sheet 13 according to the surface of the extending portion of the sheet 11, this liquid also flows from the joint portion between the sheets to the floor surface. There is no oozing in the direction.
[0029]
FIG. 3 shows a structure in which the joining sheet 11-13 in which the sheet 11 and the sheet 13 are joined and the joining sheet 14-18 in which the sheet 14 and the sheet 18 are joined are further joined at the edges. Yes. At this time, the edge portion 11-13A of the bonding sheet 11-13 and the edge portion 14-18A of the bonding sheet 14-18 are bent, and the back surface layers are bonded and bonded as shown by (i). Further, in a state where the edge portion 11-13A and the edge portion 14-18A are joined, both the edge portions are tilted in the (ii) direction and the (iii) direction, and joined onto the joining sheet 14-18.
[0030]
At this time, the edge 11-13A is longer than the folded edge 14-18A so that the edge 11-13A extends on the surface layer of the bonding sheet 14-18, and the extended edge 11- 13A is bonded to the surface layer of the bonding sheet 14-18.
[0031]
Therefore, the cross-sectional shape of the joint portion between the joint sheet 11-13 and the joint sheet 14-18 is the same as that shown in FIG.
[0032]
The folding direction of the edge 13e of the sheet 13 shown in FIG. 2 is the direction away from the opening 2, and the sheet 11 extends over the edge 13e while extending in the direction away from the opening 2. Extends to the surface of the. Similarly, the folding direction of the edge 14-18A of the joining sheet 14-18 is a direction away from the opening 2, and the edge 11-13A of the joining sheet 11-13 extends in a direction away from the opening 2. It climbs over the edge 14-18A and is bonded to the surface of the bonding sheet 14-18.
[0033]
Accordingly, the liquid flowing toward the periphery from the opening 2 is directed to the left in the drawing of FIG. 2B, and overcomes the joint along the extending direction of the edge 11e and the edge 11-13A. Will be able to escape. Since the extending direction of the edge portion 11e and the edge portion 11-13A coincides with the main flow direction of the liquid, it is difficult for the liquid to flow out from the joint portion between the sheets to the back surface side.
[0034]
In this surgical drape 1A, the sheet 11> sheets 12, 13, 14, 15> sheets 16, 17, 18, 19 are arranged in the descending order of liquid absorbency. All may be equal. In that case, the sheets 16, 15, 19 or the sheets 17, 13, 18 may be formed by one continuous sheet.
[0035]
Furthermore, the surgical drape of the present invention may be provided with a see-through part. For example, the sheet | seat 18 applicable to the edge part of 1 A of surgical drapes is formed with a transparent film instead of a nonwoven fabric, and a see-through | perspective part is provided. In this case, during the operation, the operation panel attached to the table on which the patient is placed can be seen through the fluoroscopic part, and the operation can be performed reliably and quickly.
[0036]
FIG. 4 is a plan view showing another embodiment of the surgical drape of the present invention. In the surgical drape 1B shown in FIG. 4, a U-shaped recess 3 extending to the center of the surgical drape 1B is formed at the end 1a instead of the opening 2. The surgical drape 1B is used such that the patient's head and the like are exposed from the U-shaped recess 3.
[0037]
The surgical drape 1B is formed by joining a plurality of sheets 21, 22, 23, 24, similarly to the surgical drape 1A. Each sheet has different water repellency and liquid absorbency. First, the sheet 21 provided with the U-shaped recess 3 is formed of a sheet having the highest water repellency. And in the sheet | seats 22 and 23 which continue on the right and left of the sheet | seat 21, the water repellency is made lower than the sheet | seat 21. FIG. Further, the sheet 24 continuous under the sheets 21, 22, 23 has higher liquid absorbency than the sheets 21, 22, 23. In use, the generated liquid is not absorbed around the U-shaped recess 3. And the splash etc. will be fully absorbed in the sheet | seat 24 in the position away from the surgery site | part.
[0038]
The highly water-repellent sheet 21 can be formed of a nonwoven fabric formed of hydrophobic fibers or hydrophilic fibers subjected to hydrophobic treatment, a nonwoven fabric coated with a resin, or the like. In addition, as a nonwoven fabric, the nonwoven fabric described in the surface layer 5 can be used. Furthermore, it is preferable that the sheet 21 has a three-layer structure like the sheet used for the surgical drape 1A.
[0039]
In addition, the surgical drape of the present invention is not limited to a rectangular shape, and may be a circular shape or a polygonal shape. Furthermore, the surgical drape of the present invention may be used not only for humans but also for animals.
[0040]
【The invention's effect】
As described in detail above, the surgical drape of the present invention is partially different in liquid absorbency or water repellency. Therefore, a single surgical drape can be used in various operations.
[0041]
When the surgical drape according to the present invention is formed from a plurality of sheets having different liquid absorbability or water repellency, various sheets having different functions can be combined as needed, and it is simple and low cost. Can be obtained at In this surgical drape, since there is no need to provide various functions to unnecessary portions, the ease of use as a whole is not reduced.
[0042]
Further, when the sheets are joined so that the back surfaces of the sheets face each other, the liquid on the surface does not leak to the patient side.
