Abstract

The invention discloses an auto-adhesive medical bandage capable of preventing skin allergy, belonging to the technical field of research and development of medical bandages. According to the invention, an air-permeable environment-friendly skin-friendly material is selected and used; a drug component added into the medical bandage can absorb and remove liquid and toxic substances exuding from a wound, so skin is maintained in an aseptic dry environment; force applied during pressurized binding can be adjusted, so good effect is obtained in hemostasis by compression, and a patient can easily accept the bandage; since the pressure of the auto-adhesive elastic bandage is adjustable, the bandage is good in air-permeability and adaptability, so a patient wrapped with the bandage feels comfortable and can conveniently perform small-scope movement; the bandage looks beautiful; and the bandage can be adjusted at will according to the thickness of a binding part and desired pressure, so localcompression is uniform, the bandage is properly tight and has high comfort level, and the problem of skin allergy is avoided.

Description

technical field [0001] The invention belongs to the technical field of research and development of medical bandages, in particular to a self-adhesive medical bandage for preventing skin allergies. Background technique [0002] Medical bandages are gauze bandages that bind wounds or affected areas. They are common medical supplies and come in many different varieties. The simple one is the single shed belt, made of gauze or cotton, and applied to the limbs, tail, head, and abdomen. Complex bandages are bandages of various shapes made according to the position and shape. The material is double-layer cotton cloth, and cotton of different thicknesses can be sandwiched between them. There are cloth strips around it for knotting and fixing. Chest bandages, abdominal bandages, nail bandages, etc. Special bandages are mostly used for fixation on limbs and joints. [0003] The elastic bandage is woven with natural fibers, the material is soft and extremely elastic. It is mainly u...
