Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-4, a special drainage tube for hepatobiliary surgery comprises a drainage bag 1, a drainage tube 2 arranged at the upper end of the drainage bag 1 and used for collecting biliary fluid, and a drainage tube 3 arranged at the lower end of the drainage bag 1 and used for discharging biliary fluid, wherein an air bag 7 used for blowing out massive excrement is arranged on the drainage bag 1, the air bag 7 is arranged on the drainage bag 1 through a connecting assembly 5, and the massive biliary fluid blocked at the opening of the drainage tube 3 is timely discharged through pressurization of the air bag 7;

coupling assembling 5 is including setting up connecting seat 501 on drainage bag 1 and setting up in the left screw thread seat 503 of connecting seat 501, be provided with sealing washer and first check valve 502 in the connecting seat 501, screw thread seat 503 passes through

intake pipe

4 and 7 threaded connection of gasbag, connecting seat 501 right side is provided with outlet duct 6, the one end that connecting seat 501 was kept away from to outlet duct 6 is connected with fluid-discharge tube 3, in screwing in screw thread seat 503 with intake pipe 4, the sealing washer can guarantee that gas enters into in outlet duct 6 reachs fluid-discharge tube 3 at last from intake pipe 4 simultaneously, first check valve 502 avoids courage liquid to get into in the intake pipe 4.

Further, the joints of the drain pipe 3, the drainage pipe 2 and the drainage bag 1 are all provided with second one-way valves, and the second one-way valves respectively prevent bile from flowing back into the drainage pipe 2 from the drainage bag 1 and prevent the bile from entering the drainage bag 1 from the drain pipe 3.
