Nursing and drainage device used for hepatological surgery

Abstract

The invention relates to the technical field of drainage devices, and discloses a nursing and drainage device used for hepatological surgery. The nursing and drainage device used for the hepatologicalsurgery comprises a vacuum pump, a drainage bottle and a drainage pipe, wherein the upper end of the drainage bottle is open, the upper end of the drainage bottle is connected with a first cover board through threads, a first connection pipe and a second connection pipe which are vertically arranged are inserted into the first cover board, the first connection pipe is connected with an outlet endof the vacuum pump through a first hose, the second connection pipe is connected with the tail end of the drainage pipe, an exhaust pipe is arranged at the tail end of the drainage pipe, and the exhaust pipe is connected with the outlet end of the vacuum pump through a second hose. When the device is used, negative pressure is provided for the drainage bottle by the vacuum pump, thus body fluidsof a patient are drained through the drainage pipe, and in the operation process, when the drainage pipe is blocked, outside air can be discharged into the drainage bottle through a decompression valve, so that excess negative pressure in the drainage bottle is avoided, and secondary damage to a human body is reduced.

Description

technical field [0001] The invention relates to the technical field of drainage devices, in particular to a nursing drainage device for hepatobiliary surgery. Background technique [0002] In the existing medical technology, hepatobiliary drainage is to drain the body fluid in the human body to the outside of the body through the drainage device, so as to reduce the pressure in the biliary system. The drainage tube in the prior art includes a tube body and a control line, has a simple structure, and cannot effectively treat the drained liquid. Moreover, when the diversion hole is blocked, it cannot be detected outside the body. If the negative pressure suction is continued, it will easily cause secondary damage to the human body. Therefore, a new drainage device is needed. Contents of the invention [0003] The object of the present invention is to propose a nursing drainage device for hepatobiliary surgery in order to solve the shortcomings in the prior art. [0004] In...
