Negative-pressure wound therapy system pump, mechanical

This category includes portable mechanical pumps designed to generate and maintain negative pressure for vacuum-assisted wound closure systems used in negative pressure wound therapy (NPWT). These devices are intended for treating hard-to-heal wounds such as acute, traumatic, chronic ulcers, burns, surgical wounds, and skin grafts or flaps by promoting healing through controlled suction.

These pumps operate using non-electric mechanical means, such as a spring mechanism, to create vacuum pressure and are connected to a NPWT dressing set. As specified in the reference definition, each device in this category is intended for single-use only and is not reusable.
