band-Aid

Abstract

Provided is a hemostatic plaster, comprising: a first layered element (1); a second layered element (2) provided with a first surface and a second surface, wherein the first surface is connected to the first layered element (1), an adhesive material is arranged on the second surface, and a through hole is provided in the second layered element (2); a pressure applying element (3) arranged in the through hole, wherein one end of the pressure applying element is connected to the first layered element (1), and the other end thereof is connected to a hemostatic element (4); and the hemostatic element (4), wherein when the hemostatic plaster is in a working state, the hemostatic element (4) is mainly located in the through hole. The hemostatic plaster can be tightly fitted to a part to be subjected to hemostasis and the periphery thereof without gaps, can provide a larger adhesive force, and facilitates miniaturization thereof.

Description

technical field [0001] The invention relates to a hemostatic patch, which belongs to the field of medical devices, in particular to a disposable pressure hemostatic patch. Background technique [0002] Arterial and venous blood sampling is a common inspection item. Needle holes after blood collection often require the patient himself or others to press with cotton swabs, cotton balls, etc. to stop the bleeding. Subcutaneous congestion and even infection are prone to occur when the pressure is not in place. If the infant cries after blood collection, it will be more difficult to press to stop the bleeding. If it is in the cold winter, pressing the exposed limbs for a long time may cause a cold. [0003] Furthermore, in daily life, skin bumps and damaged bleeding also require pressure to stop bleeding, but the band-aids and wound dressings commonly used on the market cannot achieve such effects. [0004] For overcoming these defects, various elastic pressure hemostatic pat...

AI Technical Summary

Problems solved by technology

[0006] 1. The elastic pressure body protrudes from the base belt. When in use, there is a certain gap between the base belt and the skin around the elastic pressure body. The base belt cannot be smoothly pasted on the skin, which may easily cause the base belt to separate from the human skin, affecting the hemostatic effect and / or the product miniaturization;

[0007] 2. The pressure is fixed, and the pressure cannot be adjusted for different parts and types of wounds, and the applicability is poor;

[0008] 3. The pressing time cannot be controlled, and some parts or some patients cannot be pressed for a long time, otherwise there is a risk of ischemic necrosis of the tissue, and the safety is poor;

[0009] 4. The product structure is complicated, the operation is complicated, the volume is large, the user experience is poor, and the cost is high
