Background
Researches find that the idea of moist healing is beneficial to the repair and healing of the wound surface. The conventional common dressing such as gauze, gauze pad and the like is not beneficial to keeping the wound surface in a moist state, and needs to be changed again, and the common dressing causes secondary injury of the wound surface when being removed due to adhesion, thereby bringing pain to patients. In order to satisfy the requirement of wet healing, hydrocolloid dressing, foam dressing, alginate dressing and the like are mostly adopted, and although the dressings can make wound wounds in a closed wet healing environment, the following problems still exist:
1. after the dressing is pasted, a negative pressure environment cannot be provided, the dressing is poor in fitting performance with a wound surface, many times, alginate, debridement glue or some antibacterial dressings applied locally fall off quickly, the use and curative effect are affected, even the antibacterial medicine contained in the antibacterial dressing is lost, and the curative effect or the curative effect of the antibacterial medicine is greatly reduced.
2. Although the wound surface can be locally pressurized and bandaged through the bandage, the local pressurization and bandaging is difficult to be carried out on special parts such as the lower jaw, the temporal part, the inner thigh, the hip, the sacral tail and the like, and the movement effect of the special parts is difficult to avoid influence.
The NPWT technology or VSD negative pressure technology has been used for moist healing therapy, but because the materials thereof are expensive, the NPWT technology or VSD negative pressure technology is generally only suitable for larger wounds, and in addition, most of the larger wounds need hospitalization, a central negative pressure or electric negative pressure suction apparatus needs to be connected with a negative pressure suction pipeline, so that the activity and life of patients are limited by continuous negative pressure suction, and particularly, the patients are inconvenient for outpatient dressing change.
