Technical Field

The utility model belongs to the relevant medical instrument field of hepatobiliary department's nursing, concretely relates to hepatobiliary department's nursing is with easy dismouting drainage device.

Background

Clinically by drainage is meant the act, process and method of drawing fluid from a body cavity or wound by means of attractive or gravitational forces. Hepatobiliary surgery may use various drainage tubes, such as a gastric tube, a T-tube, an abdominal drainage tube, a urinary tube, a thoracic drainage tube, etc., according to the condition of a patient clinically. The stomach tube utilizes the negative pressure suction effect to suck out the gas and liquid accumulated in the gastrointestinal tract so as to reduce the pressure in the gastrointestinal tract and facilitate the healing of wounds; the T-tube drainage is used for relieving obstruction, draining bile, relieving the pressure of the biliary tract, promoting the healing of the cut part of the biliary duct, supporting the biliary tract, preventing biliary stricture or facilitating biliary tract radiography and stone removal.

The existing drainage device is generally single normal pressure drainage (drainage matter naturally flows out and then is stored in a soft drainage bag) or single negative pressure drainage (drainage matter flows out under the suction of an external negative pressure device and is stored in a hard tank body). Two kinds of drainage device can not switch usually, and actually can appear once in a while and originally can't satisfy the requirements at the ordinary pressure drainage that uses occasionally clinically, need use the condition of negative pressure drainage with higher speed temporarily, and the dismouting of carrying out drainage device this moment is changed comparatively complicatedly, brings more misery for the patient on the one hand, and on the other hand also can probably produce the pollution when the dismouting.
