Abstract

The invention provides a cerebrospinal fluid drainage apparatus, which comprises a drainage tube, a liquid storage bottle and an air pump, wherein the near end of the drainage tube, the liquid storage bottle and an air inlet of the air pump are sequentially connected by virtue of pipes; the liquid storage bottle can be used for accommodating liquid; and the liquid, at least before the liquid storage bottle is full of the liquid, is prevented from flowing into the air inlet of the air pump. According to the cerebrospinal fluid drainage apparatus provided by the invention, a cerebrospinal fluid drainage rate can be controlled in an entire operation, so that brain tissue injury caused by too quick decompression of cerebral ventricle is prevented.

Description

technical field [0001] The invention relates to a medical device, in particular to a cerebrospinal fluid drainage device. Background technique [0002] The properties and pressure of cerebrospinal fluid are affected by many factors. If the central nervous system is diseased and the metabolism of nerve cells is disordered, the properties and components of cerebrospinal fluid will change; if the circulation path of cerebrospinal fluid is blocked, the intracranial pressure will increase. Cerebrospinal fluid drainage surgery is required. Excessive loss of cerebrospinal fluid will lead to a decrease in intracranial pressure and headaches, which will affect the recovery of the patient. In severe cases, it will also cause cerebellar sagging, and even endanger the life of the patient. If the cerebrospinal fluid drainage rate is too fast, it will cause subdural, epidural or intraventricular hemorrhage due to too fast ventricular decompression. [0003] The patent document with the ...
