Description

Technical Field

[0001] This utility model relates to the field of bridge pier repair technology, specifically to a comfortable pressure ulcer powder patch. Background Technology

[0002] Pressure ulcers are a type of pressure ulcer that usually occurs in people who are bedridden or sitting for long periods of time, especially those who have limited mobility and restricted local nerve and blood supply. Currently, the medical field mainly uses dressing products for pressure ulcer care, such as ointments or powders, and the wound needs to be protected during treatment. Therefore, medicated plasters or powders are very suitable. Conventional pressure ulcer powder patches need to be adhered to the skin using an adhesive method. While this fully enclosed adhesive method ensures a good fit, it results in poor breathability and affects comfort. Therefore, we propose a more comfortable pressure ulcer powder patch to solve the above problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a comfortable pressure ulcer powder patch with good overall breathability. It solves the problem that existing pressure ulcer powder patches need to be adhered to the skin through an adhesive method. While the full-coverage adhesive method ensures a good fit, it results in poor breathability and affects comfort.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a comfortable pressure ulcer powder patch, comprising an elastic base layer, and an adhesive sheet disposed on the side of the elastic base layer for adhesion and fixation, a medicated chip disposed on the lower surface of the elastic base layer, and an edge strip disposed on the surface of the elastic base layer outside the medicated chip, and a moisture-absorbing plate disposed between the medicated chip and the edge strip. The elastic base layer is a composite structure, consisting of a fabric layer and a backing film. A mesh layer is provided at the bottom of the fabric layer, and the same mesh layer is provided on the surface of the backing film. A dispersion layer is provided between the two mesh layers.

[0005] Furthermore, the edge strip is made of silicone gel, and its thickness is greater than that of the drug chip.

[0006] Furthermore, the moisture-absorbing board is woven from absorbent fibers, and the interior of the moisture-absorbing board is filled with EPE pearl cotton.

[0007] Furthermore, an adhesive layer is provided at the bottom of the adhesive sheet, and a release cover paper is provided on the outside of the adhesive layer for protection.

[0008] Furthermore, the moisture-absorbing board is provided with four vents, and the surface of the moisture-absorbing board has evenly distributed air vents, while the opposite part of the surface of the elastic base layer has the same air vents.

[0009] Furthermore, both the fabric layer and the backing membrane are made of breathable materials, and the mesh layer uses mesh fabric with a pore size of less than 1.5 mm.

[0010] Furthermore, the dispersion layer consists of multiple arrayed capsules, which are made of highly elastic resin and have a semi-circular bottom end.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This comfortable pressure ulcer powder patch has adhesive pads on the sides for local fixation, thus avoiding the tearing pain caused by traditional full-coverage adhesive patches and increasing breathability. The breathable holes on the surface of the moisture-absorbing plate and elastic base layer accelerate the discharge of moisture and heat, preventing the skin from being stuffy and damp, and ensuring comfort. 2. This comfortable pressure ulcer powder patch features a gel material edge strip that facilitates adhesion to the skin, resulting in better fit. The edge strip is also thicker than the medicated chip, reducing friction and irritation to the skin and improving wearing comfort. At the same time, the moisture-absorbing plate can quickly absorb sweat and exudate from the skin surface, keeping the wound dry and reducing the risk of infection. 3. This comfortable pressure ulcer powder patch has a semi-circular dispersion layer, which facilitates the distribution of local pressure and reduces pressure on the sore. The elasticity of the pad strip has good extensibility and can deform with skin movement, reducing traction on the skin. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 In this embodiment, a comfortable pressure ulcer powder patch includes an elastic base layer 1 and an adhesive sheet 2 disposed on the side of the elastic base layer 1 for adhesion and fixation. A drug chip 3 is disposed on the lower surface of the elastic base layer 1, and an edge strip 4 is disposed on the surface of the elastic base layer 1 outside the drug chip 3. A moisture-absorbing plate 5 is disposed between the drug chip 3 and the edge strip 4. The elastic base layer 1 is a composite structure, which includes a fabric layer 101 and a backing film 102. A mesh layer 103 is provided at the bottom of the fabric layer 101, and the same mesh layer 103 is provided on the surface of the backing film 102. A dispersion layer 104 is provided between the two mesh layers 103.

[0016] In this embodiment, an adhesive layer is provided at the bottom of the adhesive sheet 2, and a release cover paper is provided on the outside of the adhesive layer for protection.

[0017] Please see Figure 1 and Figure 2 , Figure 3 In this embodiment, the edge strip 4 is made of silicone gel material, and the thickness of the edge strip 4 is greater than the thickness of the drug chip 3.

[0018] It should be noted that the medicated patch is applied by adhering to the skin through the side adhesive piece 2, while the medicated chip 3 corresponds to the sore, and the edge strip 4 is adhered to the skin and protects the sore.

[0019] Please see Figure 2 and Figure 3 , Figure 4 In this embodiment, the moisture-absorbing board 5 is woven from water-absorbing fibers, and the interior of the moisture-absorbing board 5 is filled with EPE pearl cotton. There are four moisture-absorbing boards 5, and the surface of the moisture-absorbing board 5 is provided with evenly distributed air vents, while the surface of the elastic base layer 1 is provided with the same air vents at the opposite locations.

[0020] It should be noted that the ventilation holes of the moisture-absorbing plate 5 have a diameter of 0.8-1mm and correspond one-to-one with the ventilation holes of the elastic base layer 1, forming a vertically penetrating ventilation channel, which can significantly improve the air circulation efficiency of the patch and reduce the stuffiness.

[0021] Please see Figure 5In this embodiment, both the fabric layer 101 and the backing film 102 are made of breathable materials, the mesh layer 103 is made of mesh fabric with a pore size of less than 1.5 mm, and the dispersion layer 104 is composed of multiple pocket strips arranged in an array. The pocket strips are made of highly elastic resin material, and the bottom end of the pocket strips has a semi-circular structure.

[0022] It should be noted that pressure dispersion is achieved through the independent deformation of individual sac strips, while the highly elastic resin material ensures that the patch can still return to its original shape after repeated deformation, thus improving durability.

[0023] The working principle of the above embodiments is as follows: The adhesive patch 2 secures the patch to the skin surface via a bottom adhesive layer (the release liner must be removed before use). Its side design ensures it doesn't easily shift after application, adapting to the patient's daily activities. The medication chip 3 serves as the core treatment area, delivering powdered medication directly to the pressure ulcer wound for antibacterial, anti-inflammatory, or healing-promoting effects. The edge strip 4 (made of silicone gel, thicker than the medication chip 3) forms a surrounding buffer zone, reducing friction between the patch edge and the skin, preventing pressure marks or skin damage. Its close fit to the skin further enhances the patch's conformity. The dispersion layer 104 of the elastic base layer 1 disperses local pressure through an array of highly elastic resin strips. When the patient is lying down and under pressure, the strips deform independently to absorb pressure, preventing continuous pressure on the wound. The composite breathable structure ensures airflow, and combined with the elastic buffer of the dispersion layer 104, reduces skin stuffiness and pressure. An absorbent plate 5, with 0.8-1mm pores on the surface, quickly absorbs wound exudate and sweat, keeping the area dry.
