Airbag-based implantable wireless intracranial pressure monitoring system

Abstract

The invention relates to an airbag-based implantable wireless intracranial pressure monitoring system, comprising three parts: an intracranial pressure implantation monitoring device, an in vitro intracranial pressure data recorder, and a data management terminal, wherein the intracranial pressure implantation monitoring device comprises a shell, a gas conduit, an airbag, a gas check valve, a gas absolute pressure sensor, a temperature sensor, a control circuit, a wireless transceiver circuit, a battery, and an antenna, and the in vitro intracranial pressure data recorder comprises an antenna, a wireless transceiver circuit, a gas absolute pressure sensor, a control and data processing circuit, a display screen, and a battery. The in vitro intracranial pressure data recorder receives intracranial pressure data and intracranial temperature data measured by the intracranial pressure implantation monitoring device. The data is processed and then displayed on the display screen in real time, and the data management terminal can store and manage the intracranial pressure data for a long time. The method provided by the invention overcomes the shortcoming that the non-implantable intracranial pressure measurement method is easy to lead to infection. The airbag-based pressure measurement method has the advantages that a small opening is formed in the skull and the circuit is easily isolated from liquid.

Description

technical field [0001] The invention belongs to the technical field of medical electronics, and relates to an intracranial pressure measurement system device, in particular to an implanted wireless intracranial pressure monitoring system based on a balloon. Background technique [0002] Increased intracranial pressure (ICP, full name intracranial pressure) is a reflection of intracranial disease or intracranial secondary disease. If intracranial pressure data can be continuously monitored and the phenomenon of increased intracranial pressure can be detected in time, it is beneficial to early Find and timely treatment of increased intracranial pressure and intracranial disease, and improve the efficacy. When measuring intracranial pressure, the probe can be placed in different locations within the skull: epidural, subdural, subarachnoid, brain parenchyma, ventricle, etc. When the probe is placed in different positions, the measurement effect is different. There are two type...

AI Technical Summary

Problems solved by technology

Monitoring intracranial pressure based on a hydraulic sensor has the following disadvantages: This method requires the hydraulic sensor to be in direct contact with the intracranial fluid, which increases the difficulty of isolating the circuit components in the implanted device from the liquid, and easily leads to the failure of the electronic components in the implanted device. Contact with liquid will cause damage, and the direct contact of electronic components with intracranial fluid will also endanger the health of the monitored patient; this method requires that the hydraulic pressure sensor be directly placed on the part of the brain to be measured, and the volume of the hydraulic pressure sensor itself often cannot be made It is very small, so the opening in the skull will be relatively large during implantation surgery, increasing the risk of infection for the patient
