Anti-reflux drainage apparatus

Abstract

An anti-reflux drainage apparatus comprises an anti-reflow device and a drainage device connected with each other, wherein a liquid inlet of a first liquid balloon is connected with a liquid inlet of a second liquid balloon; a liquid outlet of the second liquid balloon is connected with a liquid inlet of a liquid storage barrel; a liquid outlet of the liquid storage barrel is connected with a liquid inlet of a drainage bag; the liquid inlet of the drainage bag and a liquid outlet thereof are provided with switches, respectively. The defect that a current clinical in-vitro drainage apparatus for cerebrospinal fluid is loose is overcome. Thus, the anti-reflux drainage apparatus is more integrated, increase in chances of intracranial infections caused by component connection-caused contamination is avoided, and the apparatus is more airtight.

Description

technical field [0001] The invention relates to a medical drainage device, specifically an external anti-reflux drainage device required for continuous drainage of cerebrospinal fluid after lumbar puncture and Ommaya capsule implantation puncture. Background technique [0002] Nowadays, after lumbar puncture and Ommaya capsule puncture, continuous drainage of cerebrospinal fluid requires an external drainage device. However, there is currently no special drainage device in clinical practice, but a common disposable drainage bag is used to connect a 1ml syringe or 2ml syringe to drain the cerebrospinal fluid. The disadvantages of continuous drainage are: [0003] 1. The existing drainage devices are scattered and poorly sealed. When the syringe and the drainage tube are not tightly connected during the connection process, it is easy to cause pollution and increase the probability of intracranial infection in patients; [0004] 2. It is not easy to observe whether the drainag...

[0002] Nowadays, after lumbar puncture and Ommaya capsule puncture, continuous drainage of cerebrospinal fluid requires an external drainage device. However, there is currently no special drainage device in clinical practice, but a common disposable drainage bag is used to connect a 1ml syringe or 2ml syringe to drain the cerebrospinal fluid. The disadvantages of continuous drainage are:

[0003] 1. The existing drainage devices are scattered and poorly sealed. When the syringe and the drainage tube are not tightly connected during the connection process, it is easy to cause pollution and increase the probability of intracranial infection in patients;

[0004] 2. It is not easy to observe whether the drainage is unobstructed. When observing, the syringe must be separated from the implanted pipeline and the drainage fluid must be emptied, so that the drainage status can be observed more intuitively;

[0005] 3. The connection of the existing drainage device cannot maintai
