Description

A kind of minimal removed of intracranial parameter detecting probe

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.

Summary of the invention

The first notch is offered on the side side wall of the stiff case, is provided with pressure sensing in first notch Device;

The rear end of the stiff case is arranged in medical gels hose, leads for wrapping up the signal wire inside stiff case Pipe and optical fiber and the processing module for connecting rear end.

Pre-buried temperature sensor in the stiff case, the temperature sensor pass through the processing module of signal wire and rear end Connection.

The rear portion of the stiff case is equipped with the cavity for grafting medical gels hose, and stiff case, which is equipped with, is used for point Second notch of glue, one end of the medical gels hose are interspersed in first in the cavity of stiff case rear end, then by second Notch carries out dispensing and mutually fixes with stiff case.

Airway is equipped in the medical gels hose.

The temperature sensor is thermistor.

The optical fiber is made of two 100 μm of single mode optical fiber, wherein a connection light source, another connection Photoelectric Detection Device.

The light source uses dual wavelength.

The stiff case is the titanium alloy shell that length is 5mm ~ 10mm length.

The titanium alloy shell is an integral molding structure.

Beneficial effects of the present invention:

The first, described front end titanium alloy shell is integrated with pressure sensor, temperature sensor, local blood oxygen saturation light Fibre can be realized measurement while to encephalic multi-physiological-parameter.

The second, described titanium alloy shell shell can guarantee internal other chips in addition to pressure sensor not by outer The influence of portion's mechanical stress.

Possess fluting in third, the titanium alloy shell, totally three, two of them are located at the upper end of shell, a position In the front end of shell.In two of upper end, one is used for placement force sensor, and medical adhesive convenient to use draws chip Foot is physically separated, and without interfering the measurement to intracranial pressure, simplifies welding procedure.

4th, the light source connecting with optical fiber at the same time, connects the another of photoelectric detection system using dual wavelength The light of dual wavelength is also collected, conducted to root optical fiber.The use of optical fiber can conduct the optical superposition of different wave length together, and lead to The algorithm of post-mature and calibration can measure the brain part blood oxygen saturation for obtaining fibre-optical probe position.
