Liver and gall drainage device used for medical general surgery department

Abstract

The invention relates to the technical field of liver and gall drainage devices, in particular to a liver and gall drainage device used for the medical general surgery department. The liver and gall drainage device comprises a barrel and a pressure regulation device, wherein the barrel is horizontally arranged; one end of the barrel is connected with one end of a drainage tube; the drainage tube is provided with a second check valve; the other end of the barrel is of an opening shape; a first piston in sliding cooperation with the inner wall of the barrel is arranged in the barrel; one side, which is far away from the drainage tube, of the first piston is connected with one end of a connecting rod; the other end of the connecting rod extends to the outer side of the barrel; and the tube body, which is near one end of the drainage tube, of the barrel is provided with two mutually corresponding connection holes. By use of the liver and gall drainage device, when a difference value between air pressure in the barrel and external air pressure is overhigh, a spring retracts under the function of atmospheric pressure, the second piston is separated from a fixing pipe or a movable pipe, at the time, external gases enter the barrel, the suction force of the device becomes small, and injuries to a patient due to overlarge strength are avoided.

Description
