Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] The optical fiber intracranial pressure monitor for intracranial pressure measurement of the present invention includes LED light source, LED driver, optical fiber sensor, multimode optical fiber, photoelectric detector, pre-amplification module, recording and processing module, and display module. Among them, one end of the optical fiber sensor is placed in the cranial cavity for sensing the pressure of the cranial cavity, and the other end of the optical fiber sensor is respectively connected to one end of a multimode optical fiber, one of which is used to input LED light, and the other end of the multimode optical fiber is connected to the LED light source. The output end of the LED light source is connected to the other end of the LED light source and the LED driver is connected. One end of the other two multimode fibers is respecti...

Abstract

The invention provides an optical fiber craniocerebral pressure monitor. An optical fiber pressure sensor in the monitor is placed in a cranial cavity, under the effect of intracranial pressure, a sensitive membrane of the optical fiber pressure sensor deforms, the reflectivity of incident lasers is changed, reflected light is transmitted to an interference filter through a multimode fiber, only the 1, 310 nm lasers enter a photoelectric detector, the photoelectric detector converts the reflected light with pressure information into electric signals, the electric signals are amplified, analyzed and processed and then displayed on a digital instrument, a recorder is used for continuously tracing a craniocerebral pressure curve, and therefore the changes of the intracranial pressure can be known at any time. The optical fiber craniocerebral pressure monitor can monitor the intracranial pressure of a patient most rapidly, visually and accurately, displays all information of changes of the craniocerebral pressure, and is widely applied to professions such as the neurosurgery, the internal medicine and the department of pediatrics.

Description

technical field [0001] The invention belongs to the technical field of photoelectric sensor research, and in particular relates to an optical fiber cranial pressure monitor for measuring intracranial pressure. The invention is suitable for patients with severe craniocerebral injuries in neurosurgery, internal medicine and pediatrics; brain tumors and cerebral blood vessels Patients after surgery; patients with possible intracranial space-occupying lesions and cerebral edema; accurate measurement of intracranial pressure changes in patients with a tendency to cerebral hemorrhage. Background technique [0002] At present, the intracranial pressure monitoring used in the market is mainly divided into two types: invasive and non-invasive. The invasive mainly includes: lumbar puncture and intraparenchymal monitoring. Subarachnoid space monitoring, neuroendoscopic monitoring, etc. Noninvasive intracranial pressure monitoring mainly includes: clinical manifestations and imaging d...
