Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of device for measuring intracranial pressure.
Background technique
Intracranial pressure (ICP) refers to cranial cavity content to generated pressure, also known as cerebral on cranial cavity wall.Due to being present in
Cavum subarachnoidale and intracisternal cerebrospinal fluid are between cranial cavity wall and brain tissue, and under arachnoid in the ventricles of the brain and spinal cavity
Chamber communicates, so the hydrostatic pressing of cerebrospinal fluid can represent intracranial pressure, usually using cranium brain Ridge fluid pressure when lateral position as representative.It wears
Cisterna magna or telocoele are pierced, with the reading that pressure-measuring pipe or pressure gauge are measured, as clinical intracranial pressure.This pressure
It is close with cerebrospinal pressure measured by lateral position lumbar puncture, therefore all with latter pressure be clinically representative.Normal encephalic
Pressure, in lateral position, adult is 0.7~2.0kPa (5~15mmHg), and children are 0.5~1.0kPa (3.5~7.5mmHg),
The highest point of telocoele wants high when this pressure ratio horizontal position.When seat waist wear pressure up to 3.3~4.0kPa (25~
30mmHg)。
The monitoring of intracranial pressure is clinically of great significance: clinically, monitoring intracranial pressure technology is applied to cranium brain wound
Application product in the treatment of the diseases such as wound, hypertensive cerebral hemorrhage, intracranial tumors, cerebrovascular disease, especially in Patients with Cerebral Trauma
A large amount of clinical data is tired out.It is most of researches show that monitoring intracranial pressure can the variation of successive reaction patient's intracranial pressure, to encephalic
The judgement of the condition of the injury and Brain edema severity and guiding treatment, assessment prognosis etc. have important directive significance.It can be real
When dynamic knowledge intracranial pressure change, be conducive to disease observation, early find increased intracranial pressure handle early；Intracranial pressure monitoring is to sentence
The important evidence of disconnected cerebral injury in patients severity and forecasting consequence；Help calculates and maintains cranium brain perfusion pressure；The ventricles of the brain are led outside
Good intracranial pressure control is played in stream, rationally dehydration.
Monitoring intracranial pressure is broadly divided into invasive intracranial pressure detection and Noninvasive intracranial pressure monitoring, invasive detection and mainly has at present
Detection, the interior detection of brain parenchym, cavum subarachnoidale detection, Epidural cavity detect, in nerve endoscope art in lumbar puncture detection, the ventricles of the brain
Detection, telemetering monitoring intracranial pressure technology etc.；Non-invasive monitoring mainly has clinical manifestation and impression inspection, vagina nervi optici diameter prison
Survey, retinal venous pressure or arterial blood pressure monitoring, TCD monitoring, flash visual evoked potential detection, periosteum displacement
Monitoring, bregma monitoring etc..
