Abstract

The invention discloses an implantable intracranial pressure monitoring probe and belongs to human cranial cavity monitoring devices. The implantable intracranial pressure monitoring probe comprises a probe body, wherein a groove is formed nearby the middle of the probe body; a pressure sensor is mounted in the groove; a thermistor is further mounted in the front end of the probe body and placed at the front end of the pressure sensor; wires of both the thermistor and the pressure sensor extend to the tail end of the probe body and are wrapped by wire protecting sleeves; one end of each wire protecting sleeve extends into a butting opening in the tail end of the prove body and is fixedly connected with the inner wall of the butting opening, and the other end of each wire protecting sleeve extends out of the probe body. As the pressure sensor and the thermistor are both mounted on the probe, the probe can simultaneously measure the intracranial pressure and temperature to further eliminate interference on monitoring of intracranial pressure from the temperature; as the pressure sensor is mounted in the groove, after the groove is sealed, the pressure sensor cannot be in contact with external liquid, and accordingly, the pressure measurement accuracy is effectively improved.

Description

technical field [0001] The invention relates to a human cranial cavity monitoring device, and more specifically, the invention mainly relates to an implantable intracranial pressure monitoring probe. Background technique [0002] The earliest ICP monitoring method is lumbar puncture manometry and it is still used today. At present, no implantable intracranial pressure monitoring probe capable of accurately monitoring intracranial pressure has been developed in China. Codman intracranial pressure monitor produced by American Johnson & Johnson is widely used in China now, which can realize intracranial pressure monitoring. The working principle is to collect the pressure signal through the "pressure-electrical signal" converter in a metal titanium box at the front of the probe and convert it into an electrical signal, which is transmitted to the external host for reading through the sensor lead wire, analyzed and stored, and finally displayed on the LCD screen However, suc...
