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.

[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 maintain a relatively sterile state. If it is wrapped with a yarn block, it will affect the observation, and the repeated opening of the yarn block cannot ensure that the connection is in a sterile state; if it is not wrapped with a yarn block, it will easily cause pollution. ;

[0006] 4. The interface of the drainage catheter is not tight, and it is easy to cause the tube to fall off when changing the position;

[0007] 5. The scale of the drainage bag is not accurate, and the drainage volume cannot be accurately counted;

[0008] 6. The existing drainage device cannot guarantee anti-reflux, which may easily cause cerebrospinal fluid reflux;

[0009] 7. Use a 2ml syringe to connect the drainage tube, because the air resistance in the drainage device is relatively large, which will affect the drainage effect of cerebrospinal fluid;

[0010] 8. It is not convenient to dump the drainage fluid in time, which may easily cause blockage in the tube and poor drainage of cerebrospinal fluid
