Problems solved by technology

Excessive drainage speed and excessive drainage may cause intracranial hemorrhage, low intracranial pressure, and pneumothorax; insufficient drainage volume and too long drainage interval will cause increased intracranial pressure, induce brain herniation, and lead to deterioration of the condition and even death
The existing cerebrospinal fluid drainage highly relies on the visual measurement and manual care of medical staff, and the monitoring methods are relatively backward. Generally, a measuring stick is used to measure the suspension height of the drainage bottle (suspended about 15cm above the ear canal of the patient), and the flow velocity and drainage volume are visually measured.
It can be seen that the existing monitoring methods have disadvantages such as low measurement accuracy, difficulty in controlling the flow rate, and high labor intensity for monitoring.

Description

technical field [0001] The embodiment of the present disclosure relates to a control and monitoring device for external drainage of cerebrospinal fluid, which belongs to the technical field of R&D and production of medical devices used by medical institutions. Background technique [0002] In current clinical practice, external drainage of cerebrospinal fluid is mainly divided into two types: external ventricular drainage and lumbar cistern drainage. External ventricular drainage is a clinical technique of puncturing the lateral ventricle through the skull, placing a drainage tube, and draining the cerebrospinal fluid into an external collection bottle; lumbar drainage refers to a special drainage tube, one end of which is placed in the patient's lumbar pool, and the other end is placed in the patient's lumbar pool. A method in which one end continuously drains cerebrospinal fluid into an extracorporeal collection bottle. External drainage of cerebrospinal fluid is widely u...
