Description

Hydrogel dressing for deep wound surface

Technical Field

The utility model relates to the technical field of hydrogel dressing, in particular to a hydrogel dressing for deep wound surfaces.

Background

Deep wound surfaces caused by burns, pressure sores, diabetic foot ulcers and the like are more common in clinical treatment. Mainly because epidermis, dermis and subcutaneous tissue of the deep wound surface are possibly severely damaged, blood circulation disorder, liquid seepage aggregation and necrotic tissue occupation are caused, and the wound surface is difficult to self-heal. Meanwhile, bacterial infection is easily caused by long-term exposure of the wound surface, so that the illness state is aggravated like deepening and expanding of the wound surface, and the healing time of the wound surface is prolonged. Thus, in addition to using preferred treatments, including but not limited to stratified thickness skin grafts, the debridement work at the early stage of treatment and the healing work at the later stage of treatment of the residual small wound are also important. On the one hand, in the early treatment stage, the wound surface has hardened slough and pus seepage, and in order to be beneficial to accelerating wound healing, effective means are needed to soften and remove or autolyze the slough. On the other hand, the later the treatment period, the more difficult the healing of the residual small wound surface is caused by the untimely skin grafting of the wound surface, the too large gap of the transplanted autologous skin patch, intractable bacterial infection and other possible factors, even though the healing is marginal, obvious scabs are left at the wound surface, and the poor healing is caused. The wet dressing can promote the healing of deep wound surface safely and effectively. However, the dressing selected should be different depending on the healing period, for example, a dressing suitable for cleaning slough is preferably a hydrocolloid dressing, a dressing suitable for suction and permeation is preferably a foam dressing, and a dressing suitable for continuously promoting healing of small wounds is preferably an antibacterial dressing, a silicone dressing and the like.

In the patent with the publication number of CN215504592U, the continuous safe and effective pain relief of the wound surface, the promotion of the repair and the healing of the deep wound surface are realized through the cooperation of the backing layer, the liquid absorbing layer, the matrix layer and the protective layer, and the adhesive can be suitable for different periods in the healing process of the deep wound surface, and a layer of low-allergic acrylate adhesive is compounded on the lower side of the matrix layer, so that secondary injury is easily caused to a wound part when the adhesive is torn off, and the duration of pain is long.
