Description
Technical field
The utility model relates to medical treatment and nursing articles, in particular to a kind of adding pressure type hemostatic dressing plaster step by step.
Background technique
With the development of biomaterials art, the material for hemostasis is also with rapid changepl. never-ending changes and improvements, but using it is more be still taut
The physics hemostasis by compression mode of band plus gauze class, this hemostatic fashion can effectively stop blooding, but process is tedious, and bleeding stopping period is long,
And the patient feels are uncomfortable.
By the invention of each researcher, it is used to stop blooding there are also new material, such as chitosan dressing, alginate dressing
Equal Biofunctional materials, have effectively promoted the hemostasis of wound, but the function of product is still relatively simple, and remove in patient deposited
When patch, the phenomenon that sticking together, secondary injury is caused to patient wound, it is in great pain.
Also there is the supporting surface for having used pressing plate as pressure in similar hemostatic adhesive bandage product, but the material matter is hard, is not appropriate for
In the recovery of wound.
Therefore, how to overcome disadvantage mentioned above, provide that a kind of haemostatic effect is significant, mitigates the hemostatic dressing plaster of patient suffering produces
Product are one it is necessary to and meaningful thing.
Utility model content
The purpose of the utility model is to overcome above-mentioned deficiencies in the prior art, and it is deposited to provide a kind of hemostasis of adding pressure type step by step
Patch, structure is simple, easy to use, while actively stopping blooding, can to the pressure of wound formation step by step, be conducive to wound hemostasis and
The protection of wound.To solve above-mentioned technical problem, technical solution provided by the utility model is：
A kind of adding pressure type hemostatic dressing plaster step by step is stacked gradually, institute from top to bottom by adhered layer, deposited sandwich layer and protective layer
Stating adhered layer is medical elastic adhesive tape, and the surface of the medical elastic adhesive tape is coated with silver, and the deposited sandwich layer is located in adhered layer
Between position, be combined by compression layer and foam sponge layer, fibrin ferment be coated on the foam sponge layer, the compression layer is fixed on stickup
On layer.The fibrin ferment applied in sandwich layer is directly contacted with wound, can activate blood platelet, has blood coagulation enhancing effect, effectively to wound
Stop blooding；For foam sponge layer as second layer structure, imbibition ability is strong, and gel is formed after imbibition, and certain pressure is formed to wound,
Enhance the haemostatic effect of fibrin ferment；Meanwhile transfer liquid expands rapidly after compression layer imbibition to compression layer after foam sponge layer imbibition,
Foam sponge layer is oppressed, further vascular compression gives full play to the adding pressure type hemostatic function of product；Silver-plated medical elastic adhesive tape has
Stronger elasticity, the adjustable pressure formed to bleeding wounds, is conducive to the healing of wound, while can prevent external microbe pair
The pollution of wound.
Further, the compression layer surface is provided with micropore, with a thickness of 2mm-3mm, shore hardness 70-80, institute
The aperture for stating micropore is 0.2mm-1mm, and micropore improves the rate of liquid aspiration of deposited sandwich layer, achievees the effect that quick imbibition.
Preferably, the compression layer is any one in compression-expansion sponge or compressed cellulose sponge, is had strong
Big imbibition and swelliong power, facilitates wound hemostasis.
Preferably, the foam sponge layer is medical polyurethane foam dressing, and with a thickness of 3mm-6mm, every gram of liquid absorption amount is 10-15
Gram.
Further, the fibrin ferment is attached to foam sponge layer surface, content 10-30IU/cm by spraying process2。
Fibrin ferment good biocompatibility can promote fibrinogen in blood to be converted into fibrin polymer, block capillary,
It can stop blooding rapidly.
Further, the elongation at break of the adhered layer is 125%-150%, silver content 30-50ppm, described
Adhered layer upper surface is coated with pressure sensitive adhesive.
Preferably, the pressure sensitive adhesive is in acrylate pressure sensitive adhesive, polyurethane contact adhesive or medical Medical PSA
Any one.
Further, the protective layer is page two, extends up to mutual covering from adhered layer both ends toward centre respectively,
Outer rim is adhesively fixed with adhered layer outer rim.
Preferably, the protective layer is Ge Laxin silicone oil paper.
The beneficial effects of the utility model are：
（1）Fibrin ferment can promote fibrinogen in blood to be converted into fibrin polymer, block capillary, can
To stop blooding rapidly, hemostatic capability is oppressed in the expansion of collaboration polyurethane foam dressing powerful imbibition ability and compression layer, makes product
Pressure step by step is formed to wound, achievees the effect that quick-acting haemostatic powder.（2）Polyurethane foam dressing has buffering as transition zone,
Powerful imbibition ability is strong, so that wound perimeter is kept dry and comfortable, improves patient comfort.（3）The utility model can effectively stop outer
The pollution of boundary microorganism, is effectively protected wound.
