Wound-assembly self-cleaning continuous negative pressure drainage device

Abstract

The invention discloses a wound-assembly self-cleaning continuous negative pressure drainage device, belongs to a medical appliance and aims at providing a negative pressure drainage device capable of adapting to deep or special-shaped wound drainage. The wound-assembly self-cleaning continuous negative pressure drainage device comprises a drainage tube embedded into VSC dressing and negative pressure sources connected with the drainage tube, wherein the drainage tube comprises a positive drainage tube group and a reverse drainage tube group; the positive drainage tube group comprises a plurality of positive drainage tubes (2), and the reverse drainage tube group comprises a plurality of reverse drainage tubes (3), and the positive drainage tubes (2) and the reverse drainage tubes (3) are arranged at intervals; the positive drainage tubes (2) are connected to a first switch (4) connected to a first negative pressure source in parallel through first diversion pipes (5); the reverse drainage tubes (3) are connected with a second switch (12) connected to a second negative pressure source in parallel through second diversion pipes (5). The wound-assembly self-cleaning continuous negative pressure drainage device is good in drainage effect and not easy to block, and is especially suitable for wound drainage of the deep or special-shaped wound.

Description

technical field [0001] The invention relates to a wound surface negative pressure drainage device, in particular to a wound surface assembled type self-cleaning continuous negative pressure drainage device, which belongs to medical equipment. Background technique [0002] Vacuum sealing drainage (VSD for short) is a brand-new treatment method that promotes wound healing through controllable negative pressure. At present, the basic configuration of a negative pressure drainage device includes a negative pressure source, a drainage tube, a porous foam cushion, a biological semipermeable membrane, and a drainage container; the drainage tube with multiple small holes distributed on the tube wall is set in the porous foam cushion. When in use, place the porous foam cushion on the wound surface, cover the porous foam cushion with a biological semipermeable membrane, seal the porous foam cushion and the drainage tube together, and connect the other end of the drainage tube to the d...
