Description

upper arm negative pressure dressing

technical field

The utility model relates to a dressing, in particular to a negative pressure dressing.

Background technique

A dressing is a dressing used to cover a sore, cut, or other damage. Negative pressure dressing refers to a dressing that can be used to bandage a wound and connect to a negative pressure source to seal the wound with negative pressure. Both clinical and research have proved that closed negative pressure beverage technology has a good therapeutic effect on chronic wounds and infected wounds, can prevent and control infection, promote blood circulation in wounds, and promote the growth of wound granulation tissue and angiogenesis.

There are a variety of general-purpose negative pressure dressings on the market today. These dressings usually include a sponge (mostly made of polyurethane or polyethylene glycol, etc.), an airtight waterproof film and a negative pressure tube (mostly made of a medical drainage tube). When performing negative pressure therapy for patients, the above-mentioned parts need to be assembled, and it takes a long time to change the dressing, and when it is used for large-area wounds, several dressings need to be spliced. In addition, when some parts of the body are injured, such as the upper arm, the existing dressing cannot be completely applied to the injured part, which affects the therapeutic effect.
