AI Technical Summary
The existing gauze protection method is not suitable for cutaneous capillary hyperplasia (RCCEP), resulting in sufficient blood supply and difficulty in blocking blood supply. In addition, when changing the dressing, it is easy to mismatch the type of hyperplasia, resulting in adhesion and tearing.
A 3D patch is designed, including a base, an anti-adhesion layer, an antibacterial layer and decompression bubbles. The structure is adapted to the type of hyperplasia. A combination of gelatin sponge bubbles and drugs is used to reduce pressure, prevent adhesion and provide hemostasis during bleeding.
It achieves better fit and protection with the hyperplasia, reduces adhesion, improves dressing change safety, and effectively stops bleeding in the event of bleeding.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical technology, and in particular relates to a RCCEP 3D stereoscopic patch for cutaneous capillary hyperplasia. Background Art
[0002] The skin is the primary organ affected by adverse reactions to ICIs, with an incidence of approximately 30% to 40%. These reactions primarily include maculopapular rash (eczema-like), dermatitis, and pruritus. RCCEP is the most common characteristic irAE associated with camrelizumab. Most cases occur early after treatment and are confined to the skin, primarily affecting the head, face, and trunk. Other sites are less common, but there is no risk of bleeding in the gastrointestinal mucosa, bronchial mucosa, or internal organs. Morphologically, these reactions can be divided into five types: "red mole," "pearl," "mulberry," "patch," and "tumor." Histopathological observations are primarily characterized by proliferation of capillary endothelial cells and increased capillaries in the dermis.
[0003] RCCEP is graded from 1 to 5, with grades 3-4 being relatively severe. After medication is suspended, friction is likely to occur. Gauze is usually used for protection to avoid bleeding. Ulceration and bleeding also require local compression to stop bleeding or local laser or surgical resection and other treatment measures. If the nodule is large and there is ulceration and bleeding, local medication can be used to stop bleeding.
[0004] The above-mentioned conventional gauze protection method and local hemostasis effect are not ideal. The main problem is that the gauze only serves as isolation. For larger protruding tumor-like structures, the gauze is not suitable for the appearance of various types of hyperplasia. The gauze is wrapped and squeezed, resulting in insufficient blood supply, which is not conducive to blocking blood supply. At the same time, the gauze covers a wide area and is not targeted at various similar point-like structures. When changing the dressing, the gauze adheres to the tumor. Summary of the Invention
[0005] The purpose of the utility model is to design a 3D stereoscopic patch for skin capillary hyperplasia RCCEP, the structure of which is adapted to the appearance of the hyperplasia type and prevents adhesion to the tumor.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A 3D patch for cutaneous capillary hyperplasia (RCCEP) is disclosed. The 3D patch comprises a base, a raised portion in the middle of the base, and an anti-adhesion layer and an antibacterial layer on the lower surface of the raised portion, from the inside out. A plurality of decompression bubbles are provided in the center and around the raised portion, which dissolve when in contact with blood, and contain medicine.
[0008] Furthermore, the raised portion corresponds to the shape of the capillary proliferation, so that the structure is conducive to matching the tumor shape, resulting in better fitting effect and better protection.
[0009] Furthermore, the anti-adhesion layer is made of vaseline gauze coated with paraffin, the antibacterial layer is made of silver ion gel, the decompression bubbles are made of gelatin sponge to form an air film, and the medicine is Yunnan Baiyao or thrombin lyophilized powder. When the 3D stereoscopic patch is normally attached to the growth, the decompression is reduced by the decompression bubbles to prevent squeezing and damage. At the same time, the bubbles create a partial gap between the growth and the 3D stereoscopic patch to reduce adhesion. When changing the dressing, the occurrence of tearing due to adhesion is minimized. The silver ion gel has a bactericidal effect. If the growth is damaged and bleeding, the blood contacts the bubbles of the gelatin sponge, and the bubbles of the gelatin sponge dissolve. The medicine therein, such as Yunnan Baiyao or thrombin lyophilized powder, can be used to stop bleeding.
[0010] Furthermore, the number of the decompression bubbles is 2-8, and the decompression bubbles are hemispherical.
[0011] Furthermore, the four sides of the base body are adhered to the skin.
[0012] The above technical solution can achieve the following beneficial effects:
[0013] The overall structure of the 3D stereoscopic patch of the utility model is completely designed according to the shape or type of capillary hyperplasia. The gelatin sponge bubbles inside it have a decompression effect, while also preventing the 3D stereoscopic patch from adhering to the vascular hyperplasia, which is convenient for dressing changes and solves the problem of conventional gauze adhering to the vascular hyperplasia.
[0014] If the growth ruptures, bleeds, etc., the air bubbles of the gelatin sponge of the utility model dissolve when encountering blood, and the Yunnan Baiyao or thrombin freeze-dried powder in the air bubbles can be used to stop the bleeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings: Example
[0021] like Figure 1-3 As shown, a 3D stereoscopic patch for skin capillary hyperplasia RCCEP, the 3D stereoscopic patch includes a base 1, a bulge in the middle of the base, Figure 1 The shape of the middle raised portion is hemispherical, and the lower surface of the raised portion is composed of an anti-adhesion layer 2 and an antibacterial layer 3 from the inside to the outside. The anti-adhesion layer is made of vaseline gauze coated with paraffin, and the antibacterial layer is made of silver ion gel. A number of decompression bubbles 5 are provided in the center and around the raised portion. The decompression bubbles 5 are made of gelatin sponge. In this embodiment 1, one decompression bubble 5 is provided in the center and four decompression bubbles 5 are provided around it. The decompression bubbles 5 are filled with medicine 4, which is Yunnan Baiyao or thrombin freeze-dried powder.
[0022] According to the actual convex shape of the growth, the raised portion can be designed to be consistent with the shape of the capillary growth, so as to achieve better fit, better fitting effect and better protection.
[0023] In the above embodiment, the number and position of the decompression bubbles can be selected according to actual conditions to achieve more precise or detailed protection or treatment.
[0024] Figure 3 As shown, the raised part of the 3D stereoscopic patch of the present invention is exactly attached to the tumor-like hyperplasia, and then the four sides of the base are attached to the skin. If the tumor-like hyperplasia is normal and not ulcerated, the decompression bubbles of the gelatin sponge material can have a decompression effect on the tumor-like hyperplasia, preventing the 3D stereoscopic patch from rubbing against it, and also preventing it from sticking to it, which is beneficial for subsequent dressing changes; if the tumor-like hyperplasia is damaged and bleeding occurs, then after the blood contacts the bubbles of the gelatin sponge, the bubbles dissolve, and the Yunnan Baiyao inside can stop the bleeding of the tumor-like hyperplasia.
[0025] Hyperplasia can be morphologically divided into five types: "red mole type", "pearl type", "mulberry type", "patch type" and "tumor type". Based on the morphological classification and the size factor, the utility model makes 3D stereoscopic stickers of different sizes.
[0026] The above are all preferred embodiments of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention are within the scope of protection of the claims attached to this application.
