Brain multistage flushing and anti-blocking drainage device

Abstract

The invention relates to a brain multistage flushing and anti-blocking drainage device. The brain multistage flushing and anti-blocking drainage device comprises a drainage tube body, a first guide tube, a positive and negative pressure elastic drainage bottle and a one-way valve; the drainage tube body is provided with a flushing hole group which communicates with a drainage cavity, the drainagetube body is connected with the positive and negative pressure elastic drainage bottle through the first guide tube, the one-way valve is installed on the first guide tube, the inner cavity of the drainage tube body is divided into a drainage cavity, a head flushing cavity and a middle flushing cavity along an axis, the drainage cavity is in communication with the inner part of the positive and negative pressure elastic drainage bottle through a first guide tube, the bottom of the positive and negative pressure elastic drainage bottle communicates with a collection container through a second guide tube, and the positive and negative pressure elastic drainage bottle is provided with an exhaust assembly. The safe conversion can be carried out between a liquid reservoir pressure-adding flushing balloon and the positive and negative pressure elastic drainage bottle, and the problems of anti-blocking, infection and pneumocranium are completely solved.

Description

technical field [0001] The invention relates to the technical field of medical or veterinary instruments, in particular to a brain multistage flushing and anti-blocking drainage device. Background technique [0002] At present, the drainage tube body used in the minimally invasive drainage of hypertensive cerebral hemorrhage hematoma cavity is prone to clogging during the drainage process, and the clogged part is generally at the drainage hole or in the drainage tube, resulting in The drainage is not smooth, and the drainage line cannot be flushed after it is blocked, and the drainage line can only be flushed and replaced. The blockage of the drainage hole needs to be flushed, and each flushing needs to add liquid medicine to the injection port, and it needs to be disinfected once , multiple injections increase the probability of infection, so a drainage device that solves the above problems is needed. Contents of the invention [0003] In order to solve the problems exis...
