Description
Technical field
This utility model relates to wound dressing, more specifically, relates to a kind of bleeding-stopping dressing.
Background technology
Hemostasis is the first step of wound healing, also is a step of most critical.Along with development of material technology, the product that has had some to be used to stop blooding in the market, use mostly be biomaterial, as chitin kind, fibrin class etc.Yet most widely used hemostasis mode remains the gauze Pressur hemostatic in hospital at present, namely is folded into the pad of corresponding size with gauze, presses the petechia by medical personnel then, till hemostasis, sometimes even reach 24 hours.The shortcoming of this method maximum is exactly consuming time, consumption power, and medical personnel can spend long time and very big energy to go to press the petechia.
In view of the effectiveness of this mode of Pressur hemostatic, the product of Pressur hemostatic binder class has also appearred on the market.Though this product has been liberated medical personnel to a certain extent, improve their work efficiency, the effectiveness of bandaging depends on medical personnel's experience to a great extent, if wrap up badly, binder also has the risk of slippage.And a lot of wound site also are not suitable for bandaging.Therefore, need more effective hemostasia products easily.
The utility model content
Technical problem to be solved in the utility model is, a kind of bleeding-stopping dressing is provided, this bleeding-stopping dressing can produce pressure from body, and keep-ups pressure under the situation of external action and stick on around the petechia not needing to apply, thereby plays haemostatic effect easily and effectively.
In order to solve the problems of the technologies described above, this utility model provides a kind of self-pressurization bleeding-stopping dressing, and this self-pressurization bleeding-stopping dressing comprises: backing layer; Inflatable absorbed layer, it is fixed on surface of backing layer; Adhesive-layer, it sticks on the surface that inflatable absorbed layer is fixedly arranged of backing layer, covers the peripheral part of backing layer at least; With optional release layer, it covers the adhesive-layer that is positioned on the backing layer peripheral part at least.
In this utility model, inflatable absorbed layer can be fixed on the backing layer by any-mode, includes but not limited to, sticks on the backing layer by adhesive, and it is first-class to be sewn to backing layer.
In an embodiment of the present utility model, inflatable absorbed layer is the absorption pad of meeting the water self-expanding.
In another embodiment of the present utility model, inflatable absorbed layer is made up of absorption pad and the air bag between absorption pad and backing layer.When using air bag, between absorption pad and air bag, can have adhesive layer.Can have lockable inflation inlet on the air bag, and the self-pressurization bleeding-stopping dressing can comprise for the device of giving airbag aeration.
In another embodiment of the present utility model, the self-pressurization bleeding-stopping dressing can also comprise the sealing coat on the opposite side with backing layer that is positioned at inflatable absorbed layer, and this sealing coat can be made up of porous polymer film.
In this utility model, the adhesive-layer on the backing layer peripheral part is used for dressing is sticked on petechia skin on every side.The backing layer peripheral part can not covered by inflatable absorbed layer, can partly be covered by inflatable absorbed layer, as long as the adhesive-layer on the backing layer peripheral part can produce enough adhesions yet.Preferred backing layer peripheral part is not covered by inflatable absorbed layer, thereby inflatable absorbed layer can be sealed fully on sticking on skin the time.
According to this utility model, in the time of on the skin around the self-pressurization bleeding-stopping dressing being sticked on the petechia, because the self-expanding absorbed layer runs into the water in the wound sepage and expands voluntarily, perhaps the inflation in the air bag of the device by inflation locks air bag then, and inflatable absorbed layer volume expands.The inflatable absorbed layer that expands is subjected to the constraint of backing, produces downward pressure.Because dressing sticks on the skin on every side of petechia, this downward pressure can keep for a long time, need not any external force.Therefore, self-pressurization bleeding-stopping dressing of the present utility model can effectively be brought into play anastalsis easily.
