Implanted intracranial pressure monitoring device, monitoring system and using method of monitoring system

Abstract

The invention relates to an implanted intracranial pressure monitoring device, a monitoring system and a using method of the monitoring system. The implanted intracranial pressure monitoring device comprises a sensing module, and the sensing module comprises a flexible substrate layer, a pressure sensing chip and a flexible coating layer; the pressure sensing chip is positioned on the flexible substrate layer, and the flexible coating layer at least coats the pressure sensing chip; the sensing module is embedded between skull and dura mater; and an in-vitro data reader matching with the implanted intracranial pressure monitoring device is used for realizing power supply, control and data transmission and reading of the implanted intracranial pressure monitoring device through wireless electromagnetic waves. According to the invention, the flexible substrate layer is used as the substrate of the implanted intracranial pressure monitoring device, and a core mainboard with low power consumption and an absolute pressure sensor with high precision, miniaturization and high reliability are adopted, so that the device has the advantages of long implantation service life, accurate monitoring, good stability, good safety and convenient implantation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an implantable intracranial pressure monitoring device, a monitoring system and a use method thereof. Background technique [0002] In the clinical work of craniotomy in neurosurgery, the patient's intracranial pressure is a crucial clinical indicator, which refers to the pressure of cerebrospinal fluid in the cranial cavity, and the normal value is 10-15 mm Hg. The increase of intracranial pressure may lead to a series of physiological dysfunction and pathological changes, manifested as headache, nausea, vomiting and other symptoms. Therefore, timely and accurate monitoring of the intracranial pressure value of patients is very important for clinical diagnosis and guidance of treatment. Significance. [0003] At present, the clinical intracranial pressure monitoring methods can be divided into two categories: invasive and noninvasive. For traditional invasi...

AI Technical Summary

Problems solved by technology

For traditional invasive monitoring methods, neurosurgery clinical units usually implant one end of the pressure probe semi-openly into the ventricle or brain tissue for monitoring by means of wires, and the other end is electrically connected to the monitoring equipment by means of wires, although This method can directly and accurately measure intracranial pressure, but this method needs to implant the pressure probe into the ventricle or brain tissue, so the operation is relatively difficult and risky, and the wired connection method is easy to cause infection in the semi-open wound

For non-invasive monitoring methods, although infections caused by invasive operations can be avoided, non-invasive monitoring methods have the problem of inaccurate indirect measurement
