The utility model discloses a kind of medical product for helping to tighten up wound, the medical product can be used as adhesive bandage, Exempt to stitch adhesive tape etc..The adhesive bandage that is made using the medical product exempts to stitch adhesive tape, and feature is：User helps without other people Bonding method according to common adhesive bandage is completed to tense the work of wound, lifts healing therapy effect.

The medical product includes：

(1) highly elastic layer：1., elongation at break high material moderate from modulus of elasticity；2. it can be produced during Tensile More than 20% stretcher strain, more than 0.1N pretension can be stored；3. there is preferable biocompatibility；

(2) high rigidity layer：The high rigidity layer is covered on the highly elastic layer, highly elastic layer is kept deformation quantity, Highly elastic layer release stretching prestressing force when the two is separated.The high rigidity layer choosing is much larger than the material of elastic layer with modulus of elasticity.

Also, the medical product may further include：

(3) adhesion layer：Highly elastic layer and skin can be connected, there is preferable biocompatibility；And

(4) wound contact layer.

Meanwhile the utility model additionally provides and manufactures a kind of ease for use stretching medical system of prestressing force for helping to tighten up wound The method of product.Preparation method is as follows：Realized by lamination and transfer printing process compound between different layers, pass through highly elastic layer single shaft Stretching applies pretension, as shown in Fig. 2 its master operation is as follows：

(1) adhesion layer is laminated compound to highly elastic layer；

(2) wound contact layer is fitted in highly elastic layer by transfer technique；

(3) highly elastic layer is stretched；

(4) high rigidity is pressed layer by layer and is combined to the highly elastic layer under extended state to keep the deformation of the highly elastic layer Amount.

Also, method of the present utility model can also be desired including ease for use stretching prestressing force medical product is cut into The step of shape, then, the ease for use of gained stretching prestressing force medical product is sterilized, sterilized and encapsulated be standby.
