Optical fiber sensing based micro intracranial multiparameter sensor

Abstract

The invention relates to an optical fiber sensing based micro intracranial multiparameter sensor. The sensor comprises a light source system, a signal processing system, a circulator and an optical fiber micro intracranial multiparameter sensor probe, wherein the broadband light sent by a light emitting diode in the light source system reaches the optical fiber micro intracranial multiparameter sensor probe after passing through the circulator; the light reflected by the optical fiber micro intracranial multiparameter sensor probe passes through the circulator again and then is received by the signal processing system; and the signal processing system detects wavelength change in the light signal via a wavelength scanning device, converts the received light signal to the electrical signal and computes the intracranial pressure and brain temperature data. The sensor has the following advantages: the sensor farthest reduces wounds and chances of infection and can be compatible with CT (computed tomography), MRI (magnetic resonance imaging) or electroencephalogram examination; and the sensor is immune to electromagnetic interference, so that the patients can undergo CT, MRI or electroencephalogram examination while undergoing intracranial pressure and brain temperature monitoring, thus greatly facilitating diagnosis and treatment.

Description

technical field [0001] The invention belongs to the field of optical fiber sensing, in particular to a miniature intracranial multi-parameter sensor based on optical fiber sensing. Background technique [0002] Severe craniocerebral injury is a common critical illness in neurology. It has the characteristics of rapid disease changes, many complications, high disability and high mortality. If it is not detected in time and treated effectively, it will cause irreversible brain damage and even endanger the patient. s life. Therefore, timely and accurate acquisition of patient's intracranial characteristic data and its changing trend is an essential means to observe the changes of patients with craniocerebral diseases, judge the timing of surgery, guide clinical medication and evaluate the prognosis, and advanced sensor technology is to achieve this. basis for a goal. [0003] The monitoring of intracranial characteristic data of patients with craniocerebral injury includes th...
