Abstract
The invention discloses a medical product for tightening a wound opening by using stretch prestress and a manufacturing method thereof, and aims at solving the problem to achieve the goal of fast heeling of the slender wound and being used for replacing suture to a certain degree. The medical product is characterized in that the stretch prestress is stored by a high-elasticity layer; the prestress is locked by a high-rigidity layer; the high-elasticity layer and the skin are bound through an adhesion layer. When the high-elasticity layer is tightly attached and bound to the skin near the wound, the high-rigidity layer is torn; the stretch prestress stored by the high-elasticity layer is released; the wound tensioning function is realized. The wound opening contact surface of the high-elasticity layer is matched to realize the functions of wound liquid absorption, sterilization, bleeding stopping and the like.
Description
Technical field
The present invention relates to medical and health field and new material manufacture field；In particular it relates to ease for use
Stretching prestressing force adhesive bandage.
Background technology
Adhesive bandage is usually used in hemostasis, antiinflammatory or the wound healing of acute minor cut or wound.Be commonly available to that otch is neat, cleaning,
The wound that table is shallow, wound is less and need not suture.Adhesive bandage is portable, easy-to-use, is family, hospital, examines essential health care
Material.
However, for the adhesive bandage in existing market, due to lacking the pressure effect to wound, its treatment to wound
Or the effect of healing acceleration is not obvious, therefore, pursuing more preferable healing therapy effect is adhesive bandage evolution urgent need to resolve
One of problem.
In addition, often utilizing drawing power to help wound healing in surgical operation, such as suturing skill exactly utilizes fine rule
Traction force drawing wound, promotes wound healing, reduces infection risk.What 3m company designed exempts to stitch adhesive tape (steri-
Strip), it is used for treating the aspects such as laceration of skin, Abscess incision drain secondary healing, common wound hemostatic ligation tool in operation
There is good clinical effectiveness.However, exempt from stitch adhesive tape ease for use in drawing wound poor, need health care professional by specialty
Apparatus applies suitable drawing power and just can use, and is unfavorable for that family and the hospital of medical condition Backward area or clinic make
With.
Content of the invention
The invention discloses a kind of medical product contributing to tightening up wound, this medical product can be used as adhesive bandage, exempts to stitch
Adhesive tape etc..The adhesive bandage that made using this medical product or exempt to stitch adhesive tape, feature is: user helps without other people can be according to
The bonding method of common adhesive bandage completes to strain the work of wound, lifts healing therapy effect.
This medical product includes:
(1) highly elastic layer: 1. select elastic modelling quantity moderate, the high material of elongation at break；2. can produce during Tensile
More than 20% stretcher strain, can store the pretension of more than 0.1n；3. there is preferable biocompatibility；
(2) high rigidity layer: described high rigidity layer covers on described highly elastic layer, makes highly elastic layer keep deformation quantity,
Highly elastic layer release stretching prestressing force when the two separates.This high rigidity layer choosing is much larger than the material of elastic layer with elastic modelling quantity.
And, this medical product may further include:
(3) adhesion layer: highly elastic layer and skin can be connected, have preferable biocompatibility；And
(4) wound contact layer.
Meanwhile, present invention also offers manufacturing a kind of ease for use contributing to tightening up wound to stretch prestressing force medical product
Method.Preparation method is as follows: is realized compound between different layers by lamination and transfer printing process, by highly elastic layer uniaxial tension
Apply pretension, as shown in Fig. 2 its master operation is as follows:
(1) adhesion layer lamination is combined to highly elastic layer；
(2) by transfer technique, wound contact layer is fitted in highly elastic layer；
(3) stretch highly elastic layer；
(4) high rigidity is pressed layer by layer the highly elastic layer being compound under extended state to keep the deformation of described highly elastic layer
Amount.
And, the method for the present invention can also include for ease for use stretching prestressing force medical product being cut into desired shape
Step, then, the ease for use of gained stretching prestressing force medical product is sterilized, is sterilized and encapsulated standby.
Brief description
When considering with reference to accompanying drawing illustrated below, the present invention can be drawn more fully by reference to detailed description
Understand.And all accompanying drawings are only explanation, rather than restricted.
