Description
Technical field
The present invention relates to clinical medicine medical instruments field, particularly to a kind of cerebrospinal fluid flow rate is controllable
Digitlization waist wears measuring cell, is widely portable to Neurology, surgery etc. and needs to be monitored patient's intracranial pressure and do waist wear
Take the occasion of cerebrospinal fluid.
Background technology
It is a kind of diagnostic operation that Neurology, surgery are often done that waist, which is worn, is mainly used in encephalitis, demyelinating disease, secondary tumour comprehensive
The discriminating of the diseases such as disease, subarachnoid hemorrhage is closed, the diagnosis and treatment to the nervous system disease have important value, Ren Heying
The importance that waist is worn can not be substituted as learning inspection.Current waist dress operation is mainly comprised the following steps：1）Patient go rest the head on prostration, Qu Jing,
Hip is bent, is nursed one's knees, both shoulders are vertical with bed surface；2）Choose waist 3-4 or waist 4-5 interstitial sites；3）Sterilization, drape, local anaesthesia；
4）Puncture needle falls through through 2 times to be felt to reach cavum subarachnoidale.5）Pressure measurement：Nook closing member is extracted, pressure-measuring pipe is connected, cerebrospinal fluid flows into pressure measurement
Pipe, reads respective value.6）Cerebrospinal fluid in pressure-measuring pipe is left and taken into chemical examination.7）Pressure-measuring pipe is pulled out, nook closing member is put back to, pulls out waist and wear
Pin, sterilization, gauze covering, local pressing, art finish.
The weak point of the operating method is：Enabling objective is single, complex operation, there is all multi-risk Systems, such as：1）Waist is worn
Pin is punctured entirely with doctors experience and feel without scale, and clinical patients generally require waist repeatedly and worn, and different doctors can be run into every time
Raw, to wear success or not to waist next time unrelated for puncture process first, can not play prompting meaning；2）For there is intracranial hypertension risk
Patient, connection pressure-measuring pipe increases the risk of hernia cerebri, and the past clinic thinks, when cerebrospinal fluid sprays or pressure-measuring pipe numerical value into line sample
More than 300mmh20（I.e. 2 glass pressure tube meters connect）Stop pressure measurement, otherwise patient has hernia cerebri risk, once hernia cerebri, patient
Probability of dying suddenly is big.3）Pressure-measuring pipe is removed after pressure measurement and gathers CSF sample again, this process operation is cumbersome, waste part cerebrospinal fluid and
It is difficult control cerebrospinal fluid flow velocity during collection cerebrospinal fluid.4）Leave and take after cerebrospinal fluid, it is difficult to estimate patient's waist wears rear pressure, it is impossible to
It is accurate instruct patient's waist wear after rest position and medication.5）Pressure measurement process steps are more, time-consuming more, considerably increase the heart of patient
Manage pressure.
Domestic patent No. ZL201420437006.0 discloses " one kind improves lumbar puncture needle ", and its technical scheme used is：
Sat and constituted by needle tubing and pin, needle point pin cutting edge of a knife or a sword dorsal part is provided with aperture, pin sits outer end and is provided with external tapping.External tapping connects flexible pipe, flexible pipe
With pressure-measuring pipe and drainage tube by triple valve control, pressure-measuring pipe is connected with pressure experience table, and drainage tube is provided with plug, external tapping
Flexible pipe can pull out, insert epidural catheter.Its advantage is simple to operate, reduces pollution probability, can control cerebrospinal fluid flow velocity, when
When monitor cerebrospinal pressure.Its weak point is that plug easily comes off, and controls csf flow effect less stable.
Domestic Patent No. ZL201220085675.7 discloses " a kind of automatic voltage measurement lumbar puncture needle ", and it is worn in common waist
The lumbar puncture needle of medical pressure sensor automatic detection cerebrospinal pressure, including needle tubing, needle stand, nook closing member, three are utilized on the basis of pin
A three-way drainage tube and two are designed on logical drainage tube, semiconductor gauge, data call wire composition, the needle stand of puncture needle
Hole, side opening is pressure sensing port, and straight hole is conduction hole.Pass through the cerebrospinal fluid and the semiconductor gauge of side opening during three-way drainage tube
Connect, after foil gauge induction pressure signal, by data wire by the incoming electron pressure detector of bio signal, electron pressure is detected
Device is converted into data signal built with signal amplification module and conversion module, by bio signal and shown.Its advantage is can be
Pressure is measured before drainage of cerebrospinal fluid, drainage is just carried out only when cerebrospinal pressure is safe, it is safer.Weak point is with straight
Conduction hole is used as at hole, it has not been convenient to which drainage takes liquid, when especially cranium pressure is higher, easily splashed.
The content of the invention
Measuring cell is worn it is an object of the invention to provide a kind of controllable digitlization waist of cerebrospinal fluid flow rate, existing skill is overcome
The deficiency of art, pressure measurement is worn by numerical pressure detection technique applied to waist, and cerebrospinal fluid can be left and taken without removing pressure-measuring pipe, and
Cerebrospinal fluid flow velocity can be adjusted according to pressure value, it is ensured that the security of waist dress operation；Can show waist wear after cranium pressure value, this to suffer from
Rest position and medication have directive significance after person's waist is worn；When Cerebrospinal Fluid in Patients hypertonia, it can read under secure conditions
