Hepatobiliary surgery drainage device with controllable negative pressure

Abstract

The hepatobiliary surgery drainage device comprises a base plate and an electric control assembly, the top of the base plate is fixedly connected with a liquid tank, a plurality of rollers are arranged at the bottom of a base, a drainage pipe is arranged at the top of the liquid tank in a penetrating mode, and the part, located outside the liquid tank, of the drainage pipe is provided with an electromagnetic reversing valve; an anti-blocking structure is arranged on the portion, located above the electromagnetic reversing valve, of the drainage pipe, the electromagnetic reversing valve is communicated with a branch pipe, a puncture head is arranged at the bottom of the drainage pipe, an atomization mask is arranged at the bottom of the branch pipe, and the electromagnetic reversing valve is communicated with the electric control assembly. The multifunctional drainage tube has the advantages that through arrangement of layering and switching connection, medicine spraying and bile liquid extraction can be carried out on a patient respectively, the multifunctional use effect is achieved, meanwhile, the drainage tube can be self-cleaned through disinfection liquid in a medicine liquid storage part, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of hepatobiliary surgery, in particular to a drainage device for hepatobiliary surgery with a controllable negative pressure. Background technique [0002] Hepatobiliary surgery mainly studies major diseases such as hepatocellular carcinoma, hepatolithiasis, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis that seriously threaten the health of Chinese people. Drainage device is a commonly used medical device in hepatobiliary surgery. For the effusion in the hepatobiliary, most of the existing drainage devices use a drainage tube and a storage bag to achieve the drainage effect on the effusion in the hepatobiliary. [0003] However, when the drainage device of the prior art is in use, on the one hand, it cannot control the negative pressure of drainage, and it is not convenient to use. Moreover, the liquid drained by the drainage device is easy to breed bacteria, and manual cleanin...

AI Technical Summary

Problems solved by technology

[0003] However, when using the drainage device in the prior art, on the one hand, it is impossible to control the negative pressure of the drainage, and it is not convenient to use; Moreover, the liquid drained by the drainage device is easy to breed bacteria, and manual cleaning is relatively difficult. Therefore, the existing drainage device needs to regularly clean the drainage tube, which is troublesome. Based on this, the present invention designs a hepatobiliary surgical drainage device with controllable negative pressure
