VSD negative-pressure irrigation drainage circulating wound protection device

Abstract

The invention discloses a VSD (vacuum sealing drainage) negative-pressure irrigation drainage circulating wound protection device. The device comprises medical PVA cotton, wherein an effusion drainage tube is embedded in an inner cavity of the medical PVA cotton, the bottom end of the effusion drainage tube penetrates through the medical PVA cotton and extends downwards, and effusion drainage holes are sequentially formed in the top of the surface of the effusion drainage tube from top to bottom. Through cooperation with the medical PVA cotton, a user ensures uniform distribution of negative pressure on a wound surface conveniently by utilizing good characteristics of the medical PVA cotton; and through cooperation of a threaded rod, an extrusion plate, a stop block and a rotary handle, the flow and time of liquid in the effusion drainage tube and a sugar liquid conveying tube are controlled conveniently, meanwhile, the flow rate of the effusion drainage tube is adjusted to be slightly lower than that of sugar liquid in the sugar liquid conveying tube, the sugar liquid is continuously and highly infiltrated and irrigated into the surface of the wound, effusion on the surface of the wound is rapidly and completely sucked by the effusion drainage holes through high negative pressure, and when the effusion drainage holes absorb the effusion, the redundant sugar liquid irrigation solution can be absorbed at the same time.

Description

technical field [0001] The invention relates to the technical field of a VSD negative pressure lavage drainage circulation wound protection device, in particular to a VSD negative pressure irrigation drainage circulation wound protection device. Background technique [0002] Fat liquefaction is one of the main reasons for poor surgical wound healing, especially when there is a lot of fat at the incision. The mechanism may be that the blood supply of the fat itself is relatively poor. The nutrients needed in the healing process are provided by the skin layer and fat. The blood circulation is relatively poor and cannot meet the nutritional needs of fat cells. Fat cells will lack nutrients and cause necrosis. [0003] At the same time, the capillaries in the adipose tissue will be embolized due to coagulation, which will further hinder the blood supply of the hypertrophic adipose tissue with poor blood supply, and cause postoperative aseptic necrosis of the adipose tissue, resu...
