Description

[0001] The invention belongs to the technical field of medical equipment, and specifically refers to an intracranial fluid drainage device. Background Art

[0002] Intracerebral effusion is a condition in which cerebrospinal fluid accumulates excessively in the ventricular system or subarachnoid space. When the amount of fluid accumulates, it will compress the brain tissue. When the cerebrospinal fluid accumulates excessively and becomes diseased, it is necessary to quickly suck out the excess cerebrospinal fluid through surgical intervention. When the cerebrospinal fluid becomes diseased, abnormal protein tissue is prone to appear, which makes the existing drainage device easy to be blocked during drainage, resulting in the drainage process not being able to proceed smoothly. In addition, the existing drainage device cannot adjust the suction force during drainage. When the patient has a lot of intracranial fluid accumulation, a larger suction force is often required to quickly clear the intracranial fluid accumulation.
