Abstract

The invention relates to a negative-pressure drainage system for the department of hepatobiliary and pancreatic surgery. The negative-pressure drainage system comprises a negative-pressure mixer, a switch valve, a hydrops bottle and a drainage tube, wherein the negative-pressure mixer is composed of a main tube and an auxiliary tube, one end of the auxiliary tube is inserted through the middle of the main tube and is completely arranged on the inner side of the main tube, the other end of the auxiliary tube is connected with an exhaust port of the hydrops bottle through the switch valve, and a drainage opening of the hydrops bottle is connected with the drainage tube. When a fluid flows through the end of the auxiliary tube in the main tube, a flow speed is increased, low pressure is generated, the negative pressure adsorption effect is generated, air in the auxiliary tube is sucked into the main tube, and negative-pressure drainage operation is achieved; and meanwhile, construction cost and use cost are extremely low, and convenience, rapidness, safety and reliability are achieved.

Description

technical field [0001] The invention relates to nursing equipment for hepatobiliary and pancreatic surgery, in particular to a negative pressure drainage system for hepatobiliary and pancreatic surgery. Background technique [0002] Diagnosis and treatment of hepatobiliary and pancreatic surgery diseases usually need to be intervened in the body through the abdomen, and the organs, tissues, and intraperitoneal body fluids or effusions need to be discharged in time to achieve further treatment and recovery of the disease. The existing methods of effusion drainage mostly use drainage Common drainage equipment uses the principle of negative pressure to suck out the effusion. It can be seen that stable negative pressure is the key to ensure the smooth implementation of drainage. At present, independent disposable negative pressure bottles or large negative pressure vials are more commonly used. The negative pressure interface of the equipment transported to each ward is realized...
