Embodiment bis-:
The schematic flow sheet of a kind of negative pressure drainage method that Fig. 4 provides for the embodiment of the present application.
In the embodiment of the present application, the negative pressure drainage device of negative pressure drainage equipment for providing in implementing one adopted in this negative pressure drainage method.
As shown in Figure 4, this negative pressure drainage method comprises the following steps:
S100: according to the shape of wound, the shape of the described porous dressing layer on described negative pressure drainage device is carried out to cutting, make the shape of described porous dressing layer and the shape of wound be complementary, and after cutting, the area of described porous dressing layer is greater than the area of wound.
Due to when producing, this negative pressure drainage device is produced according to specific specification, and when reality is used, patient's shape of wound is various, if and adopt the negative pressure drainage device that a kind of area is larger to be applied on a less wound, will cause so patient's wound uncomfortable.
So by reducing the porous dressing layer, can be so that this negative pressure drainage device can be complementary with any wound.Here said coupling refers to, the global shape of this negative pressure drainage device and the shape of wound are complementary, for example: the negative pressure drainage device of strip wound coupling be shaped as strip, being shaped as of the negative pressure drainage device of L shaped wound coupling is L shaped.
S200: described porous dressing layer is covered on wound.
Due in above-mentioned steps, the shape of porous dressing layer is cut into to the shape consistent with shape of wound, so in use, can directly the porous dressing layer be covered on the wound on patient skin.
S300: the drain adapter is connected with negative pressure equipment, and utilizes the drain adapter to apply negative pressure to the passage between coverlay and porous dressing layer.
When drain, start negative pressure equipment, negative pressure equipment is applied to the drainage channel between coverlay and porous dressing layer by the drain adapter by negative pressure, owing to interconnecting between drainage channel, so can enter into the drain adapter so that the secretions of the wound that described porous dressing layer covers passes through drainage channel, and finally be drawn out of by the drain adapter.
In addition, consideration is owing between porous dressing layer and cover layer, being provided with support component, make tectal be convenient to and the porous dressing layer between there will be the bad problem of sealing, like this when the porous dressing layer is covered with wound on the time, there will be the packing less problem of cover layer.
Now can consider, a plurality of support components 3 be adopted to the structure of cylindrical body air bag or spheroplast's air bag.Like this, as shown in Figure 5, this negative pressure drainage method, before just described porous dressing layer covers wound site, also comprises:
S400: cylindrical body air bag or spheroplast's air bag that will be positioned at the described support component of described coverlay location about puncture.
Design due to a plurality of support components 3 employing cylindrical body air bags or spheroplast's airbag structure, in use, the support component 3 that is positioned at porous dressing layer edge can be punctured, make gap between the edge of coverlay and porous dressing layer reduce, make cover layer from centre to the edge-smoothing transition, and then make sealing effectiveness between cover layer and porous dressing layer improve, be conducive to negative pressure drainage.
The above is only the application's preferred implementation, makes those skilled in the art can understand or realize the application.Multiple modification to these embodiment will be apparent to one skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the application's spirit or scope, realization in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
