Description
Technical field
The present invention relates to a kind of bandage, specifically a kind of thickening comfort type self-adhesive elastic bandage.
Background technology
Bandage is widely used in the medical fields such as operation, wound dressing, while daily as a kind of medical dressing
Also there is more application in nursing, movement protection, has primarily served support, protection, orthopedic and other specific functions.
Currently, the bandage base material of medical bandage selects polyethylene or polyvinyl chloride as back lining materials, due to not having
Gas so that wrapped skin surface steam cannot volatilize in time, form a wet environment, can not only influence the healing of wound
Speed extends the healing time of wound, and wound infection can be also caused when serious.When being wrapped up using common cohesive bandage, remove taut
When band be easy bandage is taken off together with fine hair, and can wrapped up skin surface residual under a little glue, increase use
The pain of person.
Pain and worries caused by bandage are removed in order to reduce, has occurred a kind of self-adhesive elastic bandage in the market.
Self-adhesive elastic bandage coordinates fixation because its is easy to use without other objects, and is only taut the characteristics of self-adhesive elastic bandage
It is mutually bonded with itself, without ixoderm skin, hair, clothing etc., because the characteristics of self-adhesion, the application range of self-adhesive elastic bandage is got over
Come wider, is the preferred product of medical treatment and nursing, fashion sports, pet grooming etc..In the preparation process of self-adhesive elastic bandage, one
As using natural emulsion as adhesive, which is sprayed on above the base materials such as non-woven fabrics or cotton, it is to be dried after make
Obtain self-adhesive elastic bandage.However, due to containing a small amount of soluble protein, and these soluble protein meetings in natural emulsion
Cause the allergic reaction of human skin, therefore, common self-adhesive elastic bandage is possible to that human skin can be made when in use
Allergic phenomena.Since common self-adhesive elastic bandage can cause allergic phenomena, it is thus impossible to which common self-adhesive elastic bandage is straight
It connects and is contacted with human skin or wound, this will greatly limit the use of self-adhesive elastic bandage, reduce its economic benefit.
