Cerebrospinal fluid drainage and brain temperature automatic monitoring device

Abstract

The invention relates to a cerebrospinal fluid drainage and brain temperature automatic monitoring device which at least comprises a drainage catheter, a temperature sensor and a data analysis module, wherein the drainage catheter is used for being inserted into a ventricle to drain cerebrospinal fluid to the outside from the ventricle, the temperature sensor is used for detecting temperature, and the data analysis module is used for analyzing temperature data. The temperature sensor is arranged on the outer wall of the drainage catheter to detect the temperature of the outer wall of the drainage catheter; the data analysis module calculates a drainage fluid temperature within the drainage conduit based on the detected values of the temperature sensor and thermodynamic properties of the conduit, fluid, and ambient environment. The data analysis module calculates the temperature in the ventricle based on the calculated drainage fluid temperature, the thermodynamic property of the environment and the distance information from the ventricle to the temperature detection point. The ventricular temperature can be monitored in the drainage process, temperature abnormity alarming is carried out, and hypothermia treatment is assisted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cerebrospinal fluid drainage and brain temperature automatic monitoring device. Background technique [0002] Studies have found that mild hypothermia can regulate cerebral blood flow, reduce cerebral oxygen metabolism, improve cellular energy metabolism, reduce the release of excitatory amino acids, reduce the generation of oxygen free radicals, reduce intracellular calcium overload, and increase neuronal ubiquitin production. Synthesis, reduce neuronal necrosis and apoptosis, promote the recovery of intercellular signal transmission, reduce the size of cerebral infarction, reduce cerebral edema and reduce intracranial pressure, etc. The study also found that low temperature had no effect on blood pressure, partial pressure of oxygen, partial pressure of carbon dioxide, blood pH and blood sugar, and no pathological damage was seen on the heart, lung, kidney, and small ...

AI Technical Summary

Problems solved by technology

The first detection cavity and the second detection cavity arranged side by side at the front end of the catheter make the drainage cavity of the catheter smaller, and the diameter of the drainage becomes smaller, making the device prone to blockage and difficult to dredge

In addition, the performance requirements of the drainage catheter are high, and the manufacturing process, waterproofing, and data line embedding are meticulously required, which also requires a large space for the catheter to be placed in the ventricle, and the probability of complications increases.
