in the existing clinical nursing process, if a liquid absorption layer of a wound dressing absorbs too much wound seepage liquid and the dressing is not replaced timely, wound pain, skin impregnation around the wound and dressing seepage can be caused, and the life quality of a patient is seriously influenced; if the dressing is replaced too early, the medical supplies are wasted. The existing dressing cannot visually and conveniently indicate the saturation degree of absorbed seepage to medical staff, so that the existing dressing is not convenient enough for clinical use and is not beneficial to wound healing.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a foam dressing with humidity instruction function, foam dressing self does not have humidity instruction function among the prior art has been solved, can't be directly perceived, indicate the problem of its absorptive infiltration liquid saturation to medical personnel conveniently, foam dressing self can whether carry out dressing change according to the suggestion of infiltration liquid saturation, and is practical convenient, it is untimely to have reduced because of dressing change, and the infiltration liquid that brings is revealed, the probability that skin scheduling problem takes place around flooding wound and the flooding wound, also reduced because of too early change, and the waste of the medical supplies of bringing.

The technical scheme provided by the embodiment of the application is as follows:

a foam dressing with humidity indication function comprises a waterproof layer; the liquid absorbing layer is arranged on the inner side of the waterproof layer; the humidity indicating layer is arranged between the waterproof layer and the liquid absorbing layer and is made of color-changing ink; and the wound contact layer is arranged on the inner side of the liquid absorbing layer.

Further, the adhesive further comprises a release layer.

Further, the humidity indicating layer and the liquid absorbing layer are arranged at the central position of the waterproof layer.

Further, the liquid absorbing layer is polyurethane foam.

Further, the waterproof layer is a polyurethane film.

Further, the wound contact layer is silica gel with meshes.

Furthermore, the area of the humidity indication layer is consistent with that of the liquid absorption layer, the area of the wound contact layer is consistent with that of the waterproof layer, and the area of the waterproof layer is larger than that of the humidity indication layer.

Further, the release layer is arranged on the inner side of the wound contact layer.

Furthermore, the release layer comprises a folded release film and a straight-side release film, and the straight-side release film is laminated on the folded release film.

Further, the color-changing ink is made of knitted fabrics, non-woven fabrics or wet strength paper.

The technical scheme provided in the embodiment of the application at least has the following technical effects or advantages:

1. because the humidity indicating layer is the technique of the printing ink material that discolours, has effectively solved the problem that foam dressing can't instruct its absorbed sepage saturation directly perceived, conveniently, and then has realized that foam dressing self can whether come the suggestion according to the sepage saturation and change the dressing, and is practical convenient, has reduced because of dressing change untimely, and the sepage that brings reveals, the probability that the flooding wound reaches skin scheduling problem emergence on every side, has also reduced because of too early change, and the waste of the article of doctorsing and nurses that brings.

2. Because the foam dressing still includes from the type layer, the external environment is directly arranged in to the wound contact layer that has effectively solved the foam dressing, easily receives the pollution, also causes secondary infection's problem to the patient during the use easily, adopts from the type layer and then has realized protecting the wound contact layer not to receive external pollution, uses convenient more health.

3. Because adopt humidity indication layer with the imbibition layer set up in the central point of waterproof layer puts just the area of waterproof layer is greater than humidity indication layer with the technique of the area of imbibition layer has effectively solved foam dressing absorption sepage back side leakage and with external environment contact, contacts the infection source through the sepage, leads to the problem of secondary infection, has realized the even isolated contact of sepage with the external world of waterproof layer for the wound is healed more fast.

4. Because adopt the area of humidity indication layer with the technique that the area of imbibition layer is unanimous has effectively solved the humidity indication layer of the foam dressing that has the humidity instruction function and the inadequate problem of imbibition layer seepage transmission, and then has realized that the foam dressing that has the humidity instruction function instructs its precision of seepage saturation.

5. Due to the fact that the liquid absorption layer is made of polyurethane foam, the problems that absorption rate is low and foam dressing is frequently replaced are effectively solved, water absorption rate of the foam dressing reaches 1020%, and therefore the foam dressing is not required to be frequently replaced, wound healing is faster, materials are saved, and medical waste treatment is reduced.

6. By adopting the technology that the waterproof layer is a polyurethane film, the problems of microorganism invasion and water seepage are effectively solved, the waterproof property is realized, the invasion of microorganisms is prevented, and a good healing environment can be provided for wounds.

7. Due to the adoption of the technology that the wound contact layer is silica gel with meshes, the problem that the wound can be adhered when the dressing is removed to cause secondary injury to the wound is effectively solved, so that the wound can not be adhered when the dressing is removed, the secondary injury to the wound is avoided, re-adhesion can be repeatedly uncovered, and the wound can be observed and the dressing can be replaced conveniently.
