[0002] Nipple fissures are one of the common diseases during lactation, with an incidence rate of more than 70% in lactating women. In mild cases, cracks appear on the nipple surface, while in severe cases, local exudation and bleeding occur. There are two main treatment methods. One is local drug treatment of the nipple, which can promote skin healing, but there is a risk of drug residues, causing unnecessary harm to the baby. The other is to use the protein coagulation effect of alcohol or iodine to kill pathogenic microorganisms, but it will also kill the skin tissue cells and cause secondary damage.

[0003] Therefore, designing a medical device that can safely and reliably treat mastitis is a problem that needs to be solved at present. Summary of the invention

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0025] It should be understood that terms such as “having”, “including” and “comprising” used herein do not specify the existence or addition of one or more other elements or combinations thereof.

[0026] Figure 1-4 According to an implementation form of the present invention, a protective patch for treating mastitis is provided, which includes:

[0027] A flat adhesive portion and a hemispherical wrapping portion 4 fixed at the center of the adhesive portion, the outer side of the wrapping portion 4 is a backing layer 1, the inner side is a dressing layer 5, the dressing layer 5 is a hydrocolloid dressing, and the inner surface of the hydrocolloid dressing is composed of a semipermeable membrane and a sponge-like porous structure;

[0028] The adhesive portion is provided with 1-5 opening seams 7 from the center to the surroundings, and the adhesive portion includes a backing layer 1 and an adhesive layer 2 adhered to the inner side thereof, and the other side of the adhesive layer 2 is detachably adhered to a release layer 3, and the release layer 3 entirely covers the adhesive layer 2 and the wrapping portion 4;

[0029] With this technical solution, when in use, the release layer 3 is first torn off, and then the dressing layer 5 is covered on the wound surface, wherein the hemispherical wrapping portion 4 allows the dressing layer 5 to be attached to the wound surface in accordance with the shape of the nipple, so that the protective patch fits the wound surface more closely, increases the contact area, improves the comfort of use, and has a better therapeutic effect; the adhesive portion is adhered to the skin around the nipple to fix the protective patch on the wound surface; 1-5 opening seams 7 are provided on the adhesive portion, and the wrapping portion 4 can be adjusted to ensure that it fits tightly on the wound surface; the semipermeable membrane has good sustained-release performance, which can enhance the therapeutic effect of the dressing layer 5; the sponge-like porous structure has the advantages of good elasticity and breathability; the hydrocolloid dressing acts on the wound surface, fully contacts the wound, can absorb wound exudate, effectively promotes wound healing, improves the chapped state, and resists bacterial invasion, and can play an antibacterial role; and after tearing it off, there is no residue on the skin surface, which does not harm the baby. Compared with drug application, the effect is better and safer.

[0030] The hydrocolloid dressing is formed by uniformly mixing a rubber phase and a hydrophilic colloid, wherein the mass fraction of the rubber phase is 50-55%, and the mass fraction of the hydrophilic colloid is 50-45%;

[0031] By adopting the above scheme, the hydrocolloid dressing made of the above material ratio has good water absorption effect, good softness, low adhesion, and is easier to peel off.

[0032] An annular elastic connecting portion 51 is provided at the connection between the adhesive portion and the wrapping portion 4;

[0033] With this solution, the wrapping portion 4 and the adhesive portion are connected via the elastic connecting portion 51 , and the elastic connecting portion 51 can adjust the size of the wrapping portion 4 to adapt to wound surfaces of different sizes, which is more practical.

[0034] The backing layer 1 comprises three layers, which are, from the outside to the inside, a composite non-woven fabric, silk fibroin and a chlorine dioxide sterile film.

[0035] By adopting this solution, the non-woven fabric, silk fibroin and chlorine dioxide sterile film are compounded together to form the backing layer 1, which has the beneficial effects of being moisture-proof, breathable, highly permeable and highly flexible, and can resist the invasion of bacteria.

[0036] One implementation of the protective patch for treating mastitis in the above scheme is that the diameter of the wrapping portion 4 is 1-1.2 cm. With this scheme, the diameter of the wrapping portion 4 must be greater than 1 cm to completely cover the wound surface, and a diameter exceeding 1.2 cm will cause unnecessary waste. Moreover, this method is only an illustration of a preferred example, but is not limited thereto. When implementing the present invention, the implementation mode can be based on the needs of the user.

[0037] One implementation of the protective patch for treating mastitis in the above scheme is that the shape of the planar adhesive portion is rectangular or circular. With this scheme, the use of a rectangular adhesive portion will not cause excessive material waste during production, the shape is more reasonable, and materials can be saved. The use of a circular adhesive portion can better fit the wound surface.

[0038] One implementation of the protective patch for treating mastitis in the above scheme is that the release layer 3 is glassine release paper. In this scheme, the glassine release paper has the beneficial effects of fine and uniform paper quality, good flatness, strong light transmittance and durability.

[0039] One implementation of the protective patch for treating mastitis in the above scheme is that: a protruding fixing portion 6 is further extended from the outside of the adhesive portion. In this scheme, after the release layer 3 is torn off, the adhesive layer 2 is pressed against the wound surface to press the protruding fixing portion 6, so that the protective patch can be more firmly attached to the skin and can be more convenient to tear off.

[0040] One implementation of the protective patch for treating mastitis in the above scheme is that the elastic connecting portion 51 is made of a high-elastic polyethylene carbon fiber composite resin material. In this scheme, the elastic connecting portion 51 made of the high-elastic polyethylene carbon fiber composite resin material has the advantages of good elasticity, light weight, and high strength.

[0041] One implementation of the protective patch for treating mastitis in the above scheme is that the number of the opening slits 7 is 4 and they are spaced apart on the adhesive portion. In this scheme, by providing the adhesive portion with 4 spaced apart opening slits 7, the dressing layer 5 can be better adjusted to fit the wound surface from all directions, thereby improving the user experience.

[0042] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the present invention will be obvious to those skilled in the art.

[0043] As described above, according to the present invention, the hydrocolloid dressing can promote wound healing and improve the chapped state, and can effectively treat mastitis; the semipermeable membrane and sponge-like porous structure on its surface are waterproof and breathable and can block bacterial invasion, which is safer; when in use, the hemispherical wrapping part 4 fits the wound surface in accordance with the shape of the nipple, and the treatment effect is better; the wrapping part 4 and the adhesive part are connected by an elastic connecting part 51, so that the size of the hemispherical wrapping part 4 can be stretched and adjusted to adapt to different wound surfaces; the adhesive part is provided with an opening seam 7, so that the wrapping part 4 can be adjusted to make it fit more closely on the wound surface, thereby improving the comfort of use.

[0044] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
