Description
Technical field
The invention belongs to Implanted medical system field more particularly to a kind of minimal removed of intracranial parameter detecting probes.
Background technique
In Characters of traumatic brain injury (Traumatic Brain Injury, TBI) patient, there is 20% can leave sequelae,
This group of human bodies can be influenced by sequelae for a long time in life afterwards, create a large amount of manpower, material resources and financial resources waste.
Study carefully the reason of it is wherein damaged to include Falling Injury, have a fist fight with traffic accident etc..Patients with cerebral injury is often secondary traumatic brain
Oedema (Traumatic Brain Edema, TBE) or intracranial hematoma, increase, cerebral blood flow (CBF) to will cause intracranial pressure (ICP)
Decline aggravates cerebral injury and causes patient dead.Clinically, the main monitoring index of traumatic brain edema is ICP and CBF.?
There is urgent problem to be solved in the Clinics and Practices of traumatic brain edema: lacking a kind of effective multi-parameter monitoring technology；Lack one
Kind is directed to the curative effect evaluation model of individual difference；Lack a kind of curative effect comprehensive assessment factor associated with pathologic basis.
Intracranial pressure (Intracranial Pressure, ICP) is to influence one of the principal element of cerebral blood flow (CBF), intracranial pressure
Measurement to confirm or exclude increased intracranial pressure, and determine cerebral perfusion pressure it is very necessary, this is also contributed to head trauma injury
Person carries out guiding treatment.There is a large amount of evidence to support that, using monitoring intracranial pressure, ICP monitoring has been developed as one very
Useful tool, and have become the core to serious cerebral injury patient's Intensive Care Therapy management.
Encephalic temperature (Intracranial Temperature, ICT) and intracranial pressure have certain relevance, meanwhile,
Clinically think the variation often variation earlier than ICP of ICT.In Mild Hypothermal Cerebral protection severe traumatic patients with sevious craniocerebral injury
In operation, the treatment of ICT is particularly important.
In neurosurgery, local blood oxygen saturation (rSO2) index has weight for evaluation brain oxygen metabolism and prognosis
The meaning wanted.By the measurement of brain part blood oxygen saturation, the complication of neurological disease, and predictable neural function can be found in time
The generation of energy obstacle.
Currently, clinically lacking while having the instrument of ICP/ICT/rSO2 integration test function, so that in neurosurgery
In operation, doctor using subjective and experience come the case where judging patient, can not scientific and effective guided operation, evaluation treatment effect
It is undesirable to frequently result in therapeutic effect for fruit.
Meanwhile in neurosurgery, due to lacking many kinds of parameters measuring system, limited parameter is lacked
Evaluation method, also none standardized data acquisition and storage specification.In the whole country, it is huge to seem neurosurgery amount
Greatly, a series of data are acquired, but lack unified storage standard, the analysis and identification of Future Data can not be carried out.
For this purpose, developing a kind of Data Collective of Parameters instrument in field of neurosurgery urgent need, pass through clinical and underlying diseases
Sort research and multi-parameters sampling establish clinical use codes and standards, realize clinical, basic research effective combination and breakthrough.
