Band-aid suitable for repeated flexion and extension part

Abstract

A band-aid suitable for repeated bending and stretching parts is of a composite structure formed by mutually attaching a fixing layer and an absorbent cotton layer, the absorbent cotton layer is attached to the upper face of the fixing layer, and the fixing layer is formed by weaving a first elastic body, a second elastic body and a third elastic body together. The elastic relations of the first elastomer, the second elastomer and the third elastomer are as follows: epsilon 1 < epsilon 2 < epsilon 3, 1.2 < = epsilon 2 / epsilon 1 < = 2, 1.5 < = epsilon 3 / epsilon 2, R1 < R2 < R3; the radial elasticity relationship is as follows: epsilon X1 < epsilon X2 < epsilon X3, 1.2 < = epsilon X2 / epsilon X1 < = 2, 1.5 < = epsilon X3 / epsilon X2, RX1 < RX2 < RX3; the fixing device is scientific and reasonable in design, small in application area, good in cohesiveness, small in skin irritation, good in comfort and low in production cost, the resultant force of pulling force in all directions points to the wound direction after the fixing layer is pulled, the absorbent cotton layer is pressed to be tightly attached to the surface of the wound, pressure is generated on the wound, the effects of stopping bleeding and absorbing exudate are achieved, movement is not affected, and the fixing device is suitable for popularization and application. And the method has obvious social and economic benefits.

Description

technical field [0001] The invention relates to a Band-Aid, in particular to a Band-Aid suitable for repeated flexion and extension. Background technique [0002] Band-Aids are a household emergency item that is easy to store, carry and use, and is inexpensive. As emergency supplies, Band-Aids help stop bleeding, protect wounds, prevent wound infection, facilitate the growth of wound cells, and accelerate wound healing. The existing Band-Aids are generally designed in one piece, and the body of the adhesive tape has a certain elasticity. When the existing Band-Aids are used on the parts with little movement of the wound site (such as arms and back), it has a good sticking effect. However, due to structural deficiencies, when the wound is located in a part with high bending frequency, such as knee joint and elbow joint, the traditional Band-Aid will affect the bending sensitivity of the joint and hinder the bending activity of the joint. Falls off easily. In order to solve...
