Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical supplies, in particular to a preparation method of a mesh elastic bandage. BACKGROUND

[0002] The bandage is a gauze bandage for bandaging the wound or affected area, which is a common medical supply. There are many types of bandages, the simplest of which is a single bandage made of gauze or cotton cloth, suitable for limbs, tails, heads and chest and abdomen. The complex bandage is a bandage of various shapes made according to the part and shape.

[0003] For some trauma of the limbs, especially near the joints, it is not conducive to the position of the bandage. A mesh elastic bandage can be used. The mesh elastic bandage is made of a mesh material processed by weaving, which is divided into elastic or inelastic materials and does not directly contact the wound. It is suitable for use when the human body is injured, and can be used for fingers, toes, wrists, arms, legs and other parts, and has the characteristics of simple operation, good elasticity and comfort and ventilation.

[0004] However, the traditional mesh elastic bandage is directly wrapped around the injured part of the patient by the elasticity of the elastic mesh fabric during use. The stability is affected by the material elasticity. After a certain period of use of the bandage, the fixing performance is weakened due to the decrease in material elasticity, and the bandage deviates or even falls off. The traditional mesh elastic bandage is of a one-piece structure, which needs to be cut with scissors when taken, which is time-consuming and laborious. Therefore, the technical personnel in the field provide a preparation method of a mesh elastic bandage to solve the problems in the background art. SUMMARY

[0005] (I) Technical problem to be solved

[0006] In view of the deficiencies of the prior art, the present application provides a preparation method of a mesh elastic bandage, which uses a nylon filament knitted mesh fabric with warp and weft to make an elastic mesh surface, so that the elasticity of the mesh sleeve is strong, and the mesh sleeve can be stably wrapped around the patient's limbs, providing good wrapping performance. A non-toxic glue layer is also provided, which can be used to adhere the mesh sleeve to the patient's skin stably. A winding drum with an elastic rope is also provided, which can stably position one end of the bandage body on the winding drum through the elastic rope. In addition, the bandage body is connected by a plurality of mesh sleeves, and a elastic band and an edge are provided at the connection of the mesh sleeves. When taken, the mesh sleeve can be directly torn off along the edge without using scissors or other tools for cutting. By pulling the elastic band outward, the edge is opened to solve the problems of the traditional technology, such as the decrease in fixing performance due to the decrease in material elasticity after a certain period of use of the bandage, the deviation of the bandage, and the need to use scissors for cutting when taken, which is time-consuming and laborious.
