Description

Negative pressure drainage device

Technical Field

The utility model relates to the technical field of medical devices, and more specifically to a negative pressure drainer.

Background Art

Negative pressure closed drainage technology (VSD for short) refers to using porous wound dressings to cover or fill wounds with skin and soft tissue defects, and then sealing them with biological semipermeable membranes to make them into an enclosed space. Finally, the drainage tube is connected to a negative pressure source to promote wound healing through controllable negative pressure. This is a new treatment method.
