Background

The negative pressure closed drainage technology (VSD) is brand-new methods for treating superficial wound surfaces and deep drainage, can thoroughly remove lacuna or secretion and necrotic tissues of the wound surfaces, has good treatment effect on diseases, and is an innovation of surgical treatment technology.

In general surgery, abdominal cavity surgery is often required, and for severe patients, wound healing after the abdominal cavity surgery becomes a serious challenge for recovery of the severe patients. After the infectious liquid (referred to as pus) is drained, the purposes of relieving pressure, relieving pain, relieving inflammation, preventing inflammation diffusion and facilitating inflammation regression can be achieved. The non-infectious liquid comprises blood, exudate, tissue secretion and the like, and after drainage, the aims of relieving local pressure, reducing the damage of the liquid to surrounding tissues, reducing the possibility of infection, facilitating wound healing and the like can be achieved.

The surgical drainage mechanism includes ① adsorption action, including that gauze type drainage matter is placed in the wound, the wound liquid is drained out of the body by means of suction action of gauze capillary tube, ② flow guiding action, that is, the catheter type drainage matter is placed in the wound, the wound liquid is drained out of the body by means of pressure difference between the wound liquid and atmosphere through catheter cavity, ③ siphon action, that the liquid in the cavity with higher internal position is flowed into the drainage bottle with lower internal position by means of drainage tube, and the condition is that the pressure in the cavity is equal to that in the bottle, and the liquid level in the internal tube mouth can not be exposed.

Drainage can be divided into two types, open and closed. The drainage of the adsorption and diversion is open drainage, and the defect of the drainage is that exogenous pollution is easy to occur. And the closed drainage needs to reduce the drainage port of the body surface and lead the outer end of the drainage tube to a closed container, such as the above siphon drainage and active drainage.

And to the patient of abdominal cavity operation, the drainage uses the drainage strip of yarn matter or sponge texture to carry out the drainage, but to the patient of abdominal cavity operation, what need overcome is not only bacterial infection, still include the fat liquefaction, traditional water conservancy diversion strip has better water conservancy diversion effect to interstitial fluid and pus, nevertheless, to fat water conservancy diversion effect relatively poor, especially the obese patient of abdominal type, the water conservancy diversion strip inefficacy is earlier, is unfavorable for the wound to resume.
