Description

The present invention relates to a plaster for the female genital area with a plaster main film which has a plaster inner surface which is covered by an adhesive layer which adheres to a skin in the female genital area of a user when in use and is completely covered by a cover film when not in use.

There is a risk of infection of the urinary tract, particularly in females or women and persons with female reproductive organs. Since women have a much shorter urethra (urethra), they are much more likely to be affected by urinary tract infections than men.

The outer opening of the urethra (ostium urethrae externum/ urethral entrance) is located between the labia minora, directly below the clitoris and thus in front of the vaginal entrance.

Infections of the lower urinary tract, which includes the renal pelvis, ureter, bladder, and urethra (may also be referred to as "urinary tract infections"), are mostly caused by bacteria, although viruses, fungi, and other parasites can also infect the urinary tract. The respective pathogens usually penetrate from the urinary tract exit into the urethra and from there into the urinary bladder, with the urethra and urinary bladder forming the lower urinary tract. An infection of the lower urinary tract is referred to as urethritis (inflammation of the urethra) or cystitis (inflammation of the bladder), depending on the location of the infection. From the urinary bladder, the pathogens can penetrate further into one or both ureters and from there into the left and/or right kidney. The two kidneys, the renal pelvis and the two ureters form the upper urinary tract. Infection of the renal pelvis is called pyelonephritis and infection of the ureters is called urethritis.

Most urinary tract infections are caused by transmission of pathogens that occur naturally in the intestine, e.g. Escherichia coli bacteria, from the anus via the urinary tract outlet to/via the urethra into the urinary bladder.

Recurrent UTIs can also occur when Escherichia coli bacteria that are dormant in the bladder wall become reactivated. One of the possible triggers for reactivation is the bacterium Gardnerella vaginalis, which occurs in small numbers in the vaginal flora and is known to cause vaginal inflammation, and acts as an indirect trigger here. It has been found that the risk of transmission of pathogens, e.g. Escherichia coli bacteria, Gardnerella vaginalis, via the urinary tract outlet into the urinary tract and thus the risk of a urinary tract infection is increased, especially during sexual intercourse. If the pathogens get into the urinary tract, they multiply rapidly and continue to rise within the urinary tract. This leads to inflammation of the urinary tract and causes one or more of the above infections (parallel or sequential to each other).

A vaginal patch has been proposed to prevent infection in the female genital area. In this context describes EP 2 544 643 B1 a vaginal plaster, which is intended to prevent the entry of external fluid into the vagina via the vaginal opening in a humid outdoor environment, for example in a swimming pool or in the sauna, in order to avoid infections. The patch has a central pad containing a hygienic disinfectant that conforms to the labia minora and a self-adhesive flexible liner with a release liner around the inner edge to stick the patch to the external female genitalia and surrounding skin. The patch is dimensioned in such a way that it covers the labia minora, the clitoris, the urinary tract, the vaginal entrance and, if necessary, the anus.

Covering the vaginal entrance is the vaginal patch EP 2 544 643 B1 therefore essential. The vaginal plaster only to an insignificant extent, especially if it also covers the anus, prevents the penetration of pathogens from the anus / anus via the urinary tract outlet into the urinary tract. Disadvantageously, a hygiene disinfectant such as that contained in the pad of the vaginal plaster is harmful to the vaginal flora and can disturb the (pH) balance of the vaginal flora and thus promote infections.

Against this background, it is the object of the present invention to provide a patch that solves the problems described above. In particular, a patch is to be provided which significantly minimizes the risk of a urinary tract infection.

This problem is solved by the plaster according to the invention as claimed in claim 1.

The plaster according to the invention is a (protective) plaster for use in the female genital area with a plaster main film, in particular polyurethane film, which has an inner surface of the plaster which is covered by an adhesive layer, in particular a hypoallergenic polyacrylate adhesive or a silicone adhesive adheres to a skin in the female genital area of a user and is completely covered by a cover film when not in use. The patch main film is dimensioned and designed in such a way that, when used, it completely surrounds the user's urinary tract outlet, in particular at least a large part (more than half of the area) of the large and small labia of the user, and at the same time leaves the user's vaginal entrance free or not covered.

Such a patch thus covers the outlet of the urinary tract and at the same time leaves the user's vaginal entrance free. The patch thus acts as a physical barrier to protect the urinary tract outlet from the ingress of pathogens. At the same time, the user's vaginal entrance is free, so that the plaster can be worn during sexual intercourse. Since many pathogens can get into the urinary tract outlet, particularly in this context, the patch according to the invention protects the user particularly effectively against urinary tract infections.

More precisely, the plaster and especially the main foil of the plaster is intended and designed to cover at least a large part of the mons pubis (mons pubis), a large part of the large (outer) labia (labia majora), a large part of the small (inner) labia (labia minora) , to cover the clitoris (clit), the urethra (urethra) or the urinary tract outlet and the (large and small) labia at the level of the vaginal vestibule and not to cover the vaginal entrance. The plaster or the main foil of the plaster covers the labia majora up to the level of the vaginal vestibule. In other words, when used, the patch main film covers the user's vulva (the external female genital organ) while leaving the user's vaginal entrance exposed. In this case, the plaster or the main film of the plaster does not completely cover the large labia and small labia as well as the mons pubis of the user when used.

Advantageous configurations of this patch are the subject matter of the dependent claims and are explained in more detail below.

An advantageous aspect of the patch relates to the fact that a length of the patch main film corresponds to an average vertical distance between the mons pubis and the end of the vaginal entrance facing the mons pubis, and in the application an upper longitudinal end of the patch main film faces the mons venus and a lower longitudinal end of the patch main film faces the facing the vaginal entrance.

The mean/average length of the labia majora from a variety of women is 70 to 120mm. The length of the main plaster film is therefore between 70 mm and 100 mm, in particular between 72 mm and 85 mm. Depending on the anatomy, the patch main film can be arranged on the user's vulva so that at least the urinary tract exit is covered and the vaginal entrance is left free. For example, excess foil can be shifted towards the mons pubis, i.e. for people with smaller measurements, the patch covers more of the mons pubis.

When the patch has such a length and the upper longitudinal end of the patch main sheet faces the mons pubis and the lower longitudinal end of the patch main sheet faces the vaginal entrance, the patch very securely covers the urinary tract outlet and leaves the vaginal entrance exposed when used.

It makes sense if the material thickness of the main plaster film increases, in particular continuously, from its upper longitudinal end to its lower longitudinal end.

In particular during sexual intercourse, the area in the lower longitudinal end of the plaster is subject to high friction. If the patch main sheet is reinforced in this area, the patch is more stable and therefore less sensitive to friction. It is therefore unlikely that the patch will detach (roll up), tear or be damaged in any other way at the point reinforced in this way, despite increased friction.

Provision can also be made for the main plaster film to be wider in the area of the lower longitudinal end than in the area of the upper longitudinal end.

In this way, the patch follows the natural shape of the user's large (outer) labia with its shape and can therefore be stuck particularly well and securely to the skin of these large labia.

In addition, it is possible for the lower longitudinal end of the main plaster film to run straight and for the remaining outer circumference of the main plaster film to be (convex) curved.

The lower longitudinal end of the main plaster film rests on the large, outer labia, at the level of the vaginal vestibule. So if the lower longitudinal end of the main plaster film is straight or runs straight, it can rest particularly securely and firmly on the large, outer labia at the level of the vaginal vestibule. With it the straight lower longitudinal ends support a secure hold of the patch in the female genital area. Due to the other (convex) curvature of the outer circumference of the main plaster film, the plaster is optimally adapted to the shape of the labia majora, to which the plaster mainly sticks.

It is particularly useful if the length of the straight section of the lower longitudinal end of the main plaster film is at least as long as the large, outer labia are on average wide in this area. The length of the straight section of the lower longitudinal end of the main plaster film is between 20 mm and 40 mm, preferably between 20 mm and 30 mm, particularly preferably 20 mm.

This ensures optimal adhesion of the plaster main film via the adhesive layer to the large, outer labia, at the level of the vaginal vestibule in the area of the lower longitudinal end.

It is also advantageously provided that a maximum width of the main plaster film corresponds to an average maximum horizontal distance between the outer edges of the labia majora that face away from one another, and thus in particular the maximum width of the main plaster film is between 50 mm and 70 mm, preferably between 56 mm and 66 mm and particularly preferably 59 mm. In this case, the patch main film extends in the width direction when used at least between the outer edges of the user's labia majora that face away from one another.

The average maximum horizontal distance between the opposite outer edges of the user's labia majora corresponds to an average of the corresponding distance in a variety of women. In other words, the patch is at most as wide as an average vulva.

Optimally, the patch is as wide at its widest point as the average maximum horizontal distance between the opposite outer edges of the labia majora. This allows the plaster or the main foil to lie optimally on the labia majora.

Furthermore, it can be provided that the plaster inner surface has an adhesive-free area in the middle, which is not covered by the adhesive layer and in its size and shape to the (average) size and shape of the inner labia, in particular the clitoris, of the user conforms or approximates the size and shape of the average labia minora and around the non-adhesive area the adhesive layer continuously and completely covers the inner surface of the patch.

Due to the non-adhesive area, which when used should cover the inner labia and especially the clitoris, the patch will not stick to the particularly sensitive clitoris. In this way, the clitoris is protected from contact with the adhesive layer. On the other hand, the skin of the clitoris is not irritated when the patch is removed.

Another aspect is that the adhesive-free area is provided with moisture-absorbing, hydrophilic particles.

These particles are particularly good at absorbing moisture, particularly vaginal secretions, that are present between the user's skin and the patch. This increases the wearing comfort and wearing time of the plaster or the main film of the plaster.

Alternatively, it is conceivable that the adhesive layer covers the entire plaster inner surface, but in the section that usually covers the labia minora, in particular the clitoris, moisture-absorbing, hydrophilic particles are arranged on the adhesive layer. In this way, the section of the plaster inner surface in which the moisture-absorbing, hydrophilic particles are present again forms an adhesive-free area.

It makes a lot of sense if the adhesive layer has the same thickness throughout. In this way, the patch main film adheres very evenly to the user's skin.

It is particularly advantageous if the plaster also has a stabilizing film which, when not in use, covers, in particular completely, an outer surface of the main plaster film which is opposite the inner surface of the plaster and is identical in shape, in particular non-adhesive, and the stabilizing film is stiffer and/or more stable , in particular formed of a stiffer material than the patch main sheet and is prepared and adapted to stabilize the patch main sheet for placement around the urinary tract outlet.

The patch main film itself is made of a very flexible material that can adapt well to the structure of the female genital area. For this reason, the patch is not just between the mons pubis and the vaginal entrance to position. Therefore, the stabilizing sheet temporarily stiffens the main patch sheet to allow for easy positioning and alignment of the main patch sheet relative to the female genital area. As soon as the desired position of the main patch film around the outlet of the urinary tract has been found while leaving the vaginal entrance free, the stabilizing film is removed from the main patch film.

It is very helpful if a positioning and removal device, in particular a ring-shaped positioning and removal device, protruding from the stabilization film over the circumference of the main plaster film and/or the stabilization film is attached/fixed to the stabilization film.

With the aid of the positioning and removal device, the plaster or the main film of the plaster can be positioned particularly easily and well in the female genital area (on the vulva). In addition, the stabilization film can be removed very easily and quickly from the main plaster film using the positioning and removal device. Because the positioning and removal device protrudes over the circumference of the stabilization film and/or the main patch film, the positioning and removal device can be gripped particularly easily.

In addition, it is effective if the positioning and removal device has an opening, in particular a through opening, which is dimensioned and shaped in such a way that the user can reach into the opening with at least one of her fingers, in particular the middle or index finger.

The positioning and removal device can be gripped particularly easily with the aid of the opening.

The positioning and removal device is particularly preferably designed as a ring. A ring is particularly light and easy to grip. As an alternative to this, the positioning and removal device could also have an oval, rectangular, triangular, trapezoidal or polygonal geometric shape.

Provision can furthermore be made for the positioning and removal device to be arranged at a point on the stabilization film which covers the lower longitudinal end of the main plaster film.

With the aid of the positioning and removal device arranged in this way, the lower longitudinal end of the plaster or the main plaster film can be positioned directly in front of the vaginal entrance and thus on the large, outer labia at the level of the vaginal vestibule and from there the plaster or the main plaster film can be applied to the skin in the female genital area as previously described. Thus, when the positioning and removal device is arranged at the location of the stabilizing film covering the lower longitudinal end of the main patch film, the patch can be aligned and positioned relative to the vulva in a particularly effective and simple manner.

In this context, it makes sense if the positioning and removal device is designed to be stiffer and/or more stable than the stabilizing film.

In this way, the positioning and removing device can be used particularly effectively for positioning the patch on the user and for removing the stabilizing sheet from the main patch sheet.

The positioning and removal device can be integrally connected to the stabilizing film if, for example, the positioning and removal device and the stabilizing film are made of different materials, or can be integrally formed with the stabilizing film.

In addition, it can be provided that the positioning and removal device is designed and prepared (to be grasped by the user and) as a positioning device to enable the main plaster film to be positioned on (the skin in the female genital area) of the user and as a removal device, according to Positioning of the patch main sheet against (the vulva of) the user to allow removal of the stabilizing sheet from the patch face.

With the aid of the positioning and removal device, it is therefore possible to position the plaster or the main film of the plaster on the user's vulva in a particularly simple and effective manner. Furthermore, the positioning and removal device enables the stabilization film to be removed from the main film in a very simple and rapid manner.

The positioning and removal device is conveniently used such that the user inserts a finger, preferably the index or middle finger, into the opening of the positioning and removal device. This finger then feels the vaginal entrance in order to stick the lower longitudinal end of the main plaster film in the direction of the mons pubis from there. The inserted into the positioning and removal device finger guided the stabilizing sheet away from the patch backing sheet by applying traction to the positioning and removal device once it had been adhered to the user's skin as desired.

The positioning and removal device can be designed in such a way that it is anchored in the vaginal entrance and has a tab/removal aid attached to it, which is connected to the stabilization film and with the help of which the stabilization film can be pulled off the main plaster film towards the mons pubis.

The stabilizing film and possibly also the cover film are preferably depicted in the same shape as the main film of the patch. In this way, the stabilization film optimally stabilizes the main film of the patch. The cover foil effectively protects the adhesive layer with the same shape and size as the main plaster foil.

In particular, the patch main film and preferably also the cover film and the stabilizing film (apart from the straight section of the lower longitudinal end) are egg-shaped. An egg-shaped patch main foil is particularly well adapted to the anatomy of the vulva, in particular to the course of the labia majora. If the main patch film is egg-shaped, the upper longitudinal end of the main patch film represents the (rounded) tip of the egg. The lower longitudinal end of the main patch film forms the bulbous end of the egg opposite the tip of the egg, but with a straight section.

As an alternative to the egg shape, the main plaster film can have an oval, circular, rectangular, triangular, trapezoidal or polygonal shape, each with rounded corners. Rounded corners avoid premature, unintentional detachment of the patch main film because they reduce or prevent the patch main film from rolling up.

The cover film is preferably made in two parts, with a first cover film section covering a section of the adhesive layer of the main plaster film and a second cover film section covering the remaining adhesive layer. In particular, the second cover film section also covers a section of the first cover film section. In this way, the second cover film section can be easily grasped for removal and the cover film can in this way be easily pulled off the adhesive layer.

It is particularly useful if the material of the main plaster film is (highly) flexible, waterproof and germ-proof and permeable to water vapor and gas, in particular permeable to oxygen. A plaster main film with such material properties ensures a very high wearing comfort. The (high) water vapor permeability of the patch main film prevents moisture accumulation between the user's skin and the patch or the patch main film and reduces the risk of maceration (softening of the skin). Since the film is highly flexible, it fits the user's skin like a second skin.

In particular, the adhesive force or adhesion effect of the adhesive layer is at least so great that the patch main film still adheres to the user's skin even during friction during sexual intercourse, which applies dynamic shearing stress to the adhesive layer. At the same time, the adhesive strength should not be so great / strong that removing or pulling off the main film of the plaster causes skin irritation or even injuries to the user.

Provision can preferably be made for the stabilizing film to have an adhesive layer on the side which faces the plaster outer surface in order to be temporarily connected to the plaster outer surface which is itself non-adhesive. The advantage is that the stabilization film adheres securely and firmly to the main patch film when not in use. In the application, the exposed outer surface of the plaster does not stick, so that nothing can stick to the outer surface of the plaster.

In particular, the patch main film, and sensibly also the stabilization film and/or the cover film, has a smooth surface and a smooth and rounded outer circumference. This reduces friction on the user's skin.

A particularly preferred plaster thus has a plaster main film which has a plaster inner surface which, when used, faces a user and is partially covered with an adhesive layer, and has a plaster outer surface which is opposite the plaster inner surface and, when used, faces away from a user. The patch also has a stabilizing film with a positioning and removal device attached thereto and projecting beyond the circumference of the stabilizing film and preferably also the main patch film, with the stabilizing film covering the outer surface of the patch, in particular completely (when not in use). Furthermore, the plaster has a cover film which covers the adhesive layer of the main film of the plaster, preferably completely, but which is removed from the main film of the plaster when it is used.

• Zunächst wird die Deckfolie von der Klebeschicht der Pflasterhauptfolie abgezogen. Dann wird die Pflasterinnenfläche der Pflasterhauptfolie, an deren Pflasteraußenfläche die Stabilisierungsfolie anhaftet, relativ zur Vulva mittels eines in die Positionierungs-und Entfernungsvorrichtung eingeführten Fingers an der Vulva der Anwenderin (um den Harnwegsausgang der Anwenderin herum) angeordnet bzw. positioniert. Dabei wird mit dem Finger der Vaginaleingang ertastet, um von dort ausgehend das untere Längsende der Pflasterhauptfolie mittels Klebeschicht an den großen, äußeren Schamlippen auf Höhe des Scheidenvorhofs anzuordnen und festzukleben und die restliche Pflasterhauptfolie über die Klebeschicht an der Vulva, insbesondere an den großen Schamlippen, in Richtung des Venushügels anzudrücken und infolgedessen daran festzukleben. Zuletzt wird die Stabilisierungsfolie von der Pflasterhauptfolie mittels Positionierungs- und Entfernungsvorrichtung in Richtung Venushügel hin abgezogen bzw. entfernt.

Such a patch is used as follows:

• First, the cover foil is pulled off the adhesive layer of the main plaster foil. Then, the patch inner surface of the patch main sheet, to the patch outer surface of which the stabilizing sheet is adhered, is positioned relative to the vulva on the user's vulva (around the user's urinary tract outlet) by means of a finger inserted into the positioning and removal device. The vaginal entrance is felt with the finger in order to arrange and stick the lower longitudinal end of the main plaster film from there to the large, outer labia at the level of the vaginal vestibule using an adhesive layer and the remaining main plaster film over the adhesive layer on the vulva, especially on the large labia to press in the direction of the mons pubis and consequently to stick to it. Finally, the stabilization foil is pulled off or removed from the main plaster foil by means of a positioning and removal device in the direction of the mons pubis.

Description of aspects of the present disclosure

Hereinafter, aspects of the present disclosure will be described based on the accompanying figures. The aspects shown are only examples and can be combined with one another as far as this makes technical sense.

1 Figure 12 shows a plan view of a patch 1 in use where the patch 1 is placed on a user A. To put it more precisely, in this view only an outer surface 2 of a plaster main film 3 of the plaster 1 facing away from the user A can be seen. It can be clearly seen that the plaster 1 leaves the vaginal entrance VE of the user A free or does not cover it. To be more precise, an upper longitudinal end 4 of the main patch film 3 rests on the mons pubis VH and a lower longitudinal end 5 of the main patch film 3 runs across the large, outer labia GS at the level of the vaginal vestibule SV of the user A. The main patch film 3 forms on her user A facing Surface a plaster inner surface 6, which cannot be seen in this view (but in 3 is shown). An adhesive layer 7 (also not visible here) is provided on this plaster inner surface 6 . The main plaster film 3 adheres to the skin with the aid of the adhesive layer 7, but not to the mucous membrane, the vulva or around the urinary tract outlet HA. To put it more precisely, the plaster main film 3 sticks to the skin, not the mucous membrane, of the large (outer) labia GS and follows its course through its shape. The lower longitudinal end 5 of the main plaster film sticks to the large, outer labia GS at the level of the vaginal vestibule SV.

It can be seen that the main patch film 3 is egg-shaped, with the narrow point of the egg forming the upper longitudinal end 4 of the main patch film 3 and the end of the egg facing away from the narrow point forming the lower longitudinal end 5 of the main patch film 3 . In order to be able to stick as wrinkle-free as possible to the labia majora GS at the level of the vaginal vestibule SV, the outer circumference of the main plaster film 3 is straight in the area of the lower longitudinal end 5 . In other words, at least the section of the lower longitudinal end 5 that is in contact with the labia majora at the level of the vaginal vestibule SV runs straight. The remaining outer circumference of the plaster main film 3 is (convex) curved in order to be optimally adapted to the shape of the labia majora GS.

2 12 is a longitudinal sectional view of the plaster 1. It can be seen that the plaster 1 also has a cover film 8 and a stabilizing film 9 in addition to the main film 3 of the plaster. Accordingly shows 2 the plaster 1 in non-use case, ie before use. Cover film 8 completely covers adhesive layer 7 arranged on plaster inner surface 6. Cover film 8 therefore prevents adhesive layer 7 from undesirably adhering to other objects prior to appropriate use of plaster 1 in the female genital area (on the vulva). The cover film 8 thus also protects the adhesive layer 7 from wear.

The cover film 8 is designed in two parts here. A first cover film section 8a of the cover film 8 extends from the lower longitudinal end 5 to the upper longitudinal end 4 and covers at least a lower (longitudinal) half of the plaster inner surface 6. The end section of the first cover film section 8a facing the upper longitudinal end 4 is advantageously towards the lower longitudinal end 5 folded / folded over itself and thus forms a handle bottle 8c out. This grip tab 8c, which is formed in one piece with the first cover film section 8a and forms a section of the first cover film section 8a, makes it easier to remove the first cover film section 8a from the adhesive layer 7.

A second cover film section 8b of the cover film 8 extends from the upper longitudinal end 4 to the lower longitudinal end 5 and covers the remaining plaster inner surface 6 (its upper longitudinal half) and at least one section (facing the upper longitudinal end 4) of the first cover film section 8a. In other words, a section of the second cover film section 8b overlaps the first cover film section 8a or protrudes beyond it. To remove the cover film 8 from the adhesive layer 7, the user A can simply grasp the section of the second cover film section 8b that overlaps/projects over the first cover film section 8a and thus initially pull the second cover film section 8b off the adhesive layer 7. The user A can then grasp the first cover film section 8a, in particular its grip tab 8c, and also pull it off the adhesive layer 7.

The stabilization film 9 completely covers the plaster outer surface 2. The stabilization film 9 only serves to stabilize the shape of the flexible main plaster film 3. If the main plaster film 3 is appropriately stuck on in the female genital area (after the cover film 8 has been removed from the adhesive layer 7), the stabilization film remains for that long to the patch main sheet 3 until the patch main sheet 3 is completely and satisfactorily adhered to the skin of user A's vulva, as in the context of 1 described, was glued on. Only then is the stabilizing film 9 removed from the plaster outer surface 2 of the main film 3 of the plaster.

A positioning and removal device 10 extends from (the outer periphery) of the stabilization film 9 at the point of the stabilization film 9, which covers the lower longitudinal end 5 of the plaster main film 3. The positioning and removal device 10 thus protrudes over the circumference of the stabilization film 9 as well as over the circumference of the main plaster film 3 emerges. The positioning and removal device 10 is designed here as a ring. Thus, the positioning and removal device 10 has an opening 11 . The opening 11 is dimensioned and shaped in such a way that the user A can insert at least one of her fingers, in particular her index or middle finger, into the opening 11 .

To place the patch 1 on the user A, the user A inserts at least one finger into the opening 11 of the positioning and removal device 10 (having already removed the cover sheet 8 from the adhesive layer 7). The vaginal entrance VE is then felt with this finger. Starting from the vaginal entrance VE that has been felt, the lower longitudinal end 5 of the main plaster film 3 is then stuck via the adhesive layer 7 onto the skin in the area of the vaginal vestibule SV. Proceeding from this, the remaining patch main film 3 is glued to the skin of the labia majora GS under tension as far as possible to avoid wrinkles, so that the patch 1 is applied as in 1 is oriented and positioned relative to (vulva of) user A. When the patch 1 has been applied to the desired location of user A, the stabilizing film 9 is removed from the patch outer surface 2 of the patch main film 3 by pulling on the positioning and removing device 10 in the direction of the mons pubis VH. The plaster 1 is finally arranged on the user A (as also in 1 shown).

In order that the patch 1 does not stick to objects surrounding the user A, such as her clothing, especially her underwear, the outer surface of the patch 2 is non-adhesive. The stabilization film 9 is therefore provided with an adhesive layer 12 for the purpose of temporarily fixing the stabilization film 9 to the plaster outer surface 2 .

3 12 is a plan view of the plaster inner surface 6 of the plaster main film 3. The plaster inner surface 6 is completely covered with the adhesive layer 7 except for a non-adhesive area 13, which is a portion of the plaster inner surface 6. FIG. The non-adhesive area 13 is arranged in the middle of the plaster inner surface 6 . The non-adhesive area 13 is essentially oval and thus has a stylized shape of the labia minora KS. The non-adhesive area 13 is thus located at such a point of the inner surface 6 of the plaster that, in the application, makes contact with the labia minora KS of the user A.

In 3 the egg shape of the main plaster film 3 can be clearly seen. Furthermore, the straight course of the lower longitudinal end 5 can also be seen. In addition, it can also be seen that the upper longitudinal end 4 forms the tip of the egg.

4 is a plan view of the stabilization film 9 of the patch 1. The stabilization film 9 is also egg-shaped. Advantageously, the stabilization film 9 is the same size and design as the main patch film 3. Furthermore, in 4 it can be seen that the annular positioning and removal device 10 is arranged on the stabilizing film 9 . Here the positioning and removal device 10 is in one piece with the stabilizing film 9 (from same material). However, the positioning and removal device 10 is made more stable or stiffer than the stabilizing film 9 due to the accumulation of material. The positioning and removal device 10 is on the (straight running) section of the

Arranged stabilization film 9, which is designed to cover the lower longitudinal end 5 (not visible here) of the plaster main film 3.
