[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Example 1

[0040] An anorectal dressing patch, comprising: a base layer 1, a support strip 2, a contact layer 3 and an adhesive layer 4;

[0041] like Figure 2 As shown, the upper surface of the base layer 1 is set to be the side that contacts the skin of the buttocks; a support strip 2 is set in the center of the upper surface of the base layer 1; because the base layer 1 is adhered and fixed to the skin surface over a large area during use, the base layer 1 needs to have good air permeability; the material of the base layer 1 can be made of any one of non-woven fabrics, cotton fabrics, waterproof PU and skin-friendly PE materials, and in order to improve its air permeability, a number of fine small holes can be opened on the base layer 1; in addition, a layer of waterproof film can be covered on the lower surface of the base layer 1 that does not contact the skin to increase its waterproof performance and prevent sweat and the like from soaking the base layer 1, which causes the adhesive effect to fail.

[0042] In this embodiment, the support strip 2 should be vertically arranged on the base layer 1; the contact layer 3 is covered on the top of the support strip 2, and the area of ​​the contact layer 3 is larger than the surface area of ​​the support strip 2, but smaller than the area of ​​the base layer; after the contact layer 3 completely fits and covers the support strip 2, the remaining part fits and covers the upper surface of the base layer 1, and there is a certain distance between the four sides of the contact layer 3 and the four sides of the base layer 1; during use, the contact layer 3 directly contacts the skin, and the exudate from the affected area is absorbed by the support strip 2 after passing through the contact layer 3; so the contact layer 3 needs to have good water permeability and air permeability; the material of the contact layer 3 can be selected from any one of non-woven fabrics, polyurethane foam, polyvinyl alcohol sponge, alginate fiber, chitosan fiber, and silver ion-containing fiber.

[0043] like Figure 1 as well as Figure 6 As shown, after the contact layer 3 is attached to the surface of the base layer 1, an adhesive layer 4 is coated on the entire upper surface area of ​​the contact layer 3 and the distance between the edge of the base layer 1 and the edge of the contact layer 3. The material used for the adhesive layer 4 is a medical adhesive material, which will not cause irritation to the skin and can be firmly attached to the skin. When in use, the base layer 1 and the contact layer 3 are both attached and fixed to the skin; in this way, the four sides of the base layer 1 can be attached to the skin of the buttocks, and the four sides are in a sealed state; the pollution source can be prevented from entering the dressing, and the leakage of exudate can also be prevented.

[0044] During the use of the dressing, it is the support strip 2 structure that directly absorbs the exudate from the affected area; therefore, the support strip 2 needs to form a certain protrusion structure relative to the surface of the base layer 1; in this way, the support strip 2 can be filled between the inguinal grooves, fully contact the affected area, and absorb the exudate from the affected area at all times.

[0045] In this embodiment, the shape of the support strip 2 can be selected from any of a rectangular parallelepiped, a cylinder, and a hemisphere; the length of the support strip 2 is set to 0.5 to 15 cm; the height is set to 0.5 to 8 cm; the width is set to 0.5 to 10 cm; in specific production, a dressing with a variety of sizes of support strips 2 can be provided to provide for patients with different heights and body shapes or different distribution areas of affected areas. Figure 4 As shown, this embodiment adopts a support bar 2 with a cylindrical structure.

[0046] The exudate from the patient's perianal area is directly absorbed by the support strip 2 through the contact layer 3. In the prior art, the support strip 2 is a solid structure with poor air permeability, especially after the entirety is fully soaked with the exudate, the air permeability is even worse; the patient's comfort is reduced during use, and the poor air permeability will make it impossible to keep the affected area fresh and dry, which is not conducive to the recovery and healing of the affected area.

[0047] Therefore, in this embodiment, if Figure 5 As shown, a cavity 202 structure is provided inside the support bar 2, so that the support bar as a whole forms a hollow structure; the support bar 2 itself can be made of activated carbon fiber, alginate fiber, pure cotton fiber and other materials with good water absorption and air permeability and certain support;

[0048] While retaining the function of absorbing exudate from the affected area, the hollow structure of the support strip 2 can also be ventilated normally in the cavity 202; even after the side wall of the support strip 2 absorbs the exudate, the existence of the cavity 202 does not affect the overall ventilation effect of the support strip 2; the affected area can be kept cool and dry, which helps the healing of the affected area and improves the comfort of the patient.

[0049] The hollow structure of the support strip 2 also makes the support strip 2 itself have a certain elasticity, so that it can better fit the affected area.

[0050] Example 2

[0051] Based on Example 1, in Example 1, the support bar 2 is arranged between the base layer 1 and the contact layer 3; through the base layer 1 and the contact layer 3, the middle support bar 2 is kept in a fixed position.

[0052] like Figure 7As shown, when viewed from the left or right side cross-sectional view, a placement cavity 301 structure is formed between the contact layer 3 and the base layer 1; specifically, the two sides of the contact layer 3 are attached to the surface of the base layer 1, and the middle part of the contact layer 3 is separated from the base layer to form a protrusion; thus, a placement cavity 301 is formed between the base layer 1 and the contact layer 3;

[0053] The support bar 2 is arranged in the placement cavity 301; and it is ensured that the contact layer 3 can always be in contact with and fit with the surface of the support bar 2; in this way, the support bar 2 is fixed between the base layer 1 and the contact layer 3; but if the support bar 2 is made of activated carbon fiber material, since the contact layer 3 at both ends of the support bar 2 is not closed, a small amount of carbon powder may be generated on the activated carbon fiber and leak out from the openings at both ends.

[0054] Therefore, as a preferred embodiment, the contact layers 3 at both ends of the support bar 2 are naturally folded down and pressed to fit on the base layer 1, so that the contact layers 3 close the openings at both ends of the support bar 2, thereby preventing the carbon powder on the activated carbon fiber from leaking out;

[0055] Since the support bar 2 is raised, if the contact layer 3 at both ends of the support bar 2 is directly pressed down and adhered to the base layer 1, there will be uneven adhesion on the contact layer 3. Therefore, the middle of the contact layer 3 raised from the two ends of the support bar 2 is first folded, and then naturally pressed down and adhered to the surface of the base layer 1. In this way, the adhesion of the entire contact layer 3 to the base layer 1 can be relatively smooth; and the way the contact layer 3 is adhered and fixed in this way also makes the placement cavity for placing the support bar 2 have a spindle shape.

[0056] Example 3

[0057] Based on Example 1, in Example 1, the air permeability of the support strip 2 is mainly generated by the cavity 202 structure; in order to further improve the air permeability of the support strip, this embodiment provides the following improved structure;

[0058] like Figure 4 As shown, in this embodiment, a plurality of through holes 201 are provided on the side wall of the support bar 2. The diameter of these through holes 201 can be 1 mm, or can be smaller or slightly larger, as long as the arrangement of the through holes 201 does not affect the structure of the support bar 2 itself and does not affect the filling effect of the support bar 2 in the crotch;

[0059] The through holes 201 formed on the support strip 2 can further enhance the ventilation effect of the support strip 2 itself, so that the support strip 2 can be in good ventilation contact with the affected skin through the contact layer 3, thus keeping the affected skin cool and dry; and accelerating the healing cycle of the affected skin.

[0060] In addition, although the support strip 2 with a cavity structure also has certain elastic deformation and recovery performance after deformation; a number of through holes 201 are opened on the side wall of the support strip 2, which will further improve the adaptive deformation performance and the rebound recovery performance after deformation of the entire support strip 2; in this way, the support strip 2 can better contact and fit with the affected area at the inguinal groove, and can fully absorb the exudate from the affected area.

[0061] Example 4

[0062] Based on Example 1, the adhesive layer 4 on the upper surface of the base layer 1 is directly adhered to the skin, and the contact layer 3 is in direct contact with the skin; and the anal area is a site where bacteria are more likely to breed; if bacteria breed and invade the ulcerated area, it is likely to cause infection.

[0063] Therefore, in this embodiment, an antibacterial layer is coated on the contact surface of the contact layer 3 and the skin; the antibacterial layer can inhibit the growth of excessive bacteria and prevent infection of the affected area. The antibacterial layer can be made of chitosan coating, silver ion coating, alginate coating, etc.

[0064] Example 5

[0065] Based on Example 1, in order to keep the adhesive layer 4 and the contact layer 3 structure on the base layer 1 of the dressing from being contaminated before use; Figure 1 As shown, when the dressing is not in use, the upper surface of the base layer 1 and the contact layer 3 is covered with a release paper layer 5; the shape and size of the release paper layer 5 are the same as those of the base layer 1; the release paper completely covers the upper surface of the base layer 1 and the contact layer 3 structure; before use, the release paper can be torn off.
