Multifunctional medical negative-pressure drainage device

Abstract

The invention discloses a multifunctional medical negative-pressure drainage device. The multifunctional medical negative-pressure drainage device comprises a miniature negative-pressure pump, a wasteliquid collecting tank and an alcohol tank and is characterized in that a first negative-pressure pipe and a second negative-pressure pipe are connected to the miniature negative-pressure pump, the first negative-pressure pipe is connected with a liquid drainage bottle, and the second negative-pressure pipe is connected to a gas drainage bottle; the wall of a U-shaped pipe is provided with a slide cavity and a barrier cavity, slide rails are symmetrically arranged in the slide cavity, the wall of the U-shaped pipe is provided with a communication opening, a squeezing plate is fixedly connected to a rubber piston block through a connecting rod, springs are symmetrically arranged on two sides of the squeezing plate, and one ends, away from the squeezing plate, of the springs are fixed to the U-shaped pipe. The multifunctional medical negative-pressure drainage device has the advantages that various substances such as blood and smoke can be constantly drained, frequent drainage bottle changing is not needed, the trouble caused by single drainage substance is avoided, multiple drainage bottles can be cleaned only by pressing the squeezing plate, disassembling and reassembling are notneeded, and use convenience is achieved.

Description

technical field [0001] The invention relates to the technical field of drainage devices, in particular to a multifunctional medical negative pressure drainage device. Background technique [0002] Negative pressure drainage is a necessary treatment for various operations. For large-scale operations or operations with a large amount of blood, the capacity of a single negative pressure suction bottle cannot meet the surgical requirements. When the blood in the negative pressure suction bottle is full, the operation must be suspended. The replacement of the negative pressure suction bottle hinders the smooth progress of the operation, and even causes harm to the patient. In addition, the commonly used negative pressure suction device is only connected to one suction head to complete the cleaning of one substance. For some operations, especially There is a lot of smoke in laparoscopic surgery, and two-way suction must be used to clean up the blood and smoke at the same time. Fin...

AI Technical Summary

Problems solved by technology

[0004] However, there are still relatively obvious defects in its use: 1. The capacity of the drainage bottle is limited. If the drainage material exceeds a certain amount, the negative pressure in the bottle will be low, and the drainage effect will not be achieved, and the drainage cannot be performed without interruption. ; 2. The drainage pipeline is relatively simple, which cannot meet the needs of drainage of blood, smoke, etc. during the operation; 3. The cleaning process is more troublesome, and it needs to be disassembled and assembled one by one, which is time-consuming and laborious
