Intracranial pressure monitoring system probe and calibrating method thereof

Abstract

The invention discloses an intracranial pressure monitoring system probe. The intracranial pressure monitoring system probe comprises a probe contact, and a control module which is connected with the probe contact; a storing unit is integrated to the control module; the control module is at least used for storing a null drift value acquired by the probe contact to the storing unit, and calibrating an intracranial state monitoring system probe according to the null drift value stored in the storing unit. Compared with the prior art, the intracranial pressure monitoring system probe has the advantages that the storing unit is additionally arranged in the control module and used for storing the null drift value, the calibration value can be called by software to remove error during use, and thus the automatic calibration can be realized under the matching of the software; the probe is convenient to use; the calibration value can be avoided being manually recorded by a doctor, and re-calibration is saved although a new terminal system is replaced.

Description

technical field [0001] The invention belongs to the field of implantable medical systems, in particular to a probe of an intracranial pressure monitoring system and a calibration method thereof. Background technique [0002] The monitoring of intracranial status is an important medical observation step before and after cranial cavity surgery. Taking the monitoring of intracranial pressure as an example, the common way to judge whether the intracranial pressure is increased is to use the following three accurate measurement methods for confirmation : (1) The cerebrospinal fluid was obtained by lumbar puncture for analysis; (2) X-rays were taken to check the brain gyrations, bone suture separation, thinning of the inner plate of the skull, and enlargement of the saddle; (3) Brain ultrasonography Sound detection. Among them, the (1) method is an invasive measurement, which has problems of infection and applicability to patients. The (2) method is a non-invasive measurement, bu...

Problems solved by technology

Because the probe of the intracranial pressure monitor will be affected by different environmental factors such as pressure and temperature, the medical staff must first calibrate the probe when using the probe of the intracranial pressure monitor for the first time. The current practice is to insert the probe into the into normal saline, a calibration value will be displayed on the monitor associated with the probe at this time, and the medical staff will zero the probe according to the calibration value and then insert the probe into the patient’s brain for monitoring, but when it is replaced When using a monitor, medical staff need to recalibrate the probe. This process will not only cause cumbersome use, but also prone to human errors, resulting in calibration errors
