Embodiment Construction

[0013] Below with reference to accompanying drawing 1, the present invention is described in detail by embodiment.

[0014] Use 80g / L sodium sulfide to remove hair on the top of the head of the patient, spread a sterile surgical towel for routine disinfection, cut the skin, subcutaneous and periosteum in an arc at the front edge of the parietal bone, and turn the skin, subcutaneous and periosteum back to the parietal bone. Pull apart the muscle to expose the bone surface, and clean the bone surface; scrub the bone surface with ethanol and chloroform to remove organic matter and keep it dry; apply "502" glue on the base of the sensor 2, and paste it on the outer surface of the skull parietal bone of the patient under test At measuring point 1, finger press for 1.5 to 3 minutes; the surface is coated with neoprene rubber to prevent moisture; insulated wires are used as strain gauge lead-out lines, and after the buffer ring is reserved, the head lead-out wires are welded on the he...

Abstract

The present invention provides a micro-invasive intracranial pressure detection system and its application method, belonging to the field of craniocerebral detection technology. Said system includes the following several portions: sensor, electric bridge measurement circuit, signal amplification circuit, phase-sensitive detection circuit, filter circuit, data acquisition circuit, strain correction system, calvaria and dura mater encephalic viscoelasticity processing system, result display, oscillating circuit and power supply, in which the strain correction system and calvaria and dura mater encephalic viscoelasticity processing system are formed into a microcomputer processing system. Besides, said invention also provides the concrete steps of its application method.

Description

technical field [0001] The invention belongs to the technical field of craniocerebral detection, and in particular provides a minimally invasive intracranial pressure detection system and an application method thereof. Background technique [0002] There are many critically ill patients in cranial neurosurgery, and their conditions change rapidly, so craniocerebral surgery is very risky. Whether it is craniotomy, drilling or puncture, the determination of the operation timing will play a vital role in the life and death of craniocerebral patients, so it is very important to measure the intracranial pressure index directly related to the degree of cranial injury clinically, quickly, objectively and accurately. Accurate intracranial pressure detection is one of the necessary means to observe the condition changes of patients with craniocerebral diseases, judge the timing of surgery, guide clinical medication and evaluate the prognosis, and it plays a key role in timely judgmen...
