Abstract

The invention discloses a self-adaption encephalic cerebrospinal fluid drainage device which comprises a drainage catheter (1), a connecting catheter (2) and a liquid storage device (3). A drainage controller (6) is arranged on the connecting catheter (2); a pressure sensor (13) is arranged at the front end of the drainage catheter (1) and connected with the drainage controller (6) through a data line (12); the pressure sensor (13) is used for monitoring encephalic pressure and sending monitored pressure information to the drainage controller (6); the drainage controller (6) is used for controlling the drainage speed and drainage amount of liquid in the drainage catheter (1) according to the pressure information sent by the pressure sensor (13). The self-adaption encephalic cerebrospinal fluid drainage device can continuously monitor the encephalic pressure change condition of a patient in real time, the drainage amount can be precisely adjusted dynamically according to the monitoring result, and the drainage amount is precisely measured and controlled through a flowmeter.

Description

technical field [0001] The invention belongs to the technical field of a cerebrospinal fluid drainage device for patients clinically, and particularly relates to a device for self-adaptive regulation of cerebrospinal fluid drainage volume according to intracranial pressure after neurosurgery. Background technique [0002] Clinically, cerebrospinal fluid drainage is a treatment method often used in neurology. It is a safe, effective and minimally invasive treatment for various types of hydrocephalus, subarachnoid hemorrhage and a small number of unresectable intracranial tumors. Approach to neurosurgical diseases such as increased intracranial pressure. It continuously draws out the cerebrospinal fluid, which can not only reduce the intracranial pressure, but also promote the discharge of inflammatory cerebrospinal fluid, prevent and alleviate immediate complications, significantly improve the nervous system function of the patient, and promote the recovery of the patient. ...
