Description
Technical field
The utility model is related to clinical medicine medical instruments field, particularly to a kind of cerebrospinal fluid flow rate can
The digitlization waist of control wears measuring cell, and being widely portable to Neurology, surgery etc. needs that patient's intracranial pressure is monitored and done
Waist wears the occasion for taking cerebrospinal fluid.
Background technology
It is a kind of diagnostic operation that Neurology, surgery are often done that waist, which is worn, and it is comprehensive to be mainly used for encephalitis, demyelinating disease, secondary tumour
The discriminating of the diseases such as disease, subarachnoid hemorrhage is closed, there is important value, Ren Heying to the diagnose and treat of the nervous system disease
The importance that waist is worn can not be substituted as learning inspection.Waist dress operation mainly comprises the following steps at present：1）Patient goes pillow to lie down, 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）Disinfection, drape, local anaesthesia；
4）Puncture needle falls through through 2 times to be felt up to cavum subarachnoidale.5）Pressure measurement：Needle core is extracted, connects pressure-measuring pipe, 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, needle core is put back to, pulls out waist and wear
Needle, disinfection, gauze covering, part pressing, art finish.
The shortcoming of the operating method is：Enabling objective is single, complicated for operation, there are all multi-risk Systems, such as：1）Waist is worn
Needle is without scale, and puncture is entirely with doctors experience and feel, and clinical patients generally require waist repeatedly and wear, and can encounter different doctors every time
Raw, it is unrelated to wear waist next time success or not for puncture process for the first time, 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 acquires CSF sample again, this process is cumbersome, waste part cerebrospinal fluid and
It is difficult control cerebrospinal fluid flow velocity in the process to acquire cerebrospinal fluid.4）After leaving and taking 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, take the heart for more, considerably increasing patient
Manage pressure.
Domestic patent No. ZL201420437006.0 discloses " a kind of improvement lumbar puncture needle ", the technical solution adopted is that：
It is made of needle tubing and needle seat, needle point needle cutting edge of a knife or a sword back side is equipped with aperture, and needle sits outer end and is equipped with external tapping.External tapping connection flexible pipe, hose
It is controlled with pressure-measuring pipe and drainage tube by triple valve, pressure-measuring pipe is connected with pressure experience table, and drainage tube is equipped with plug, on external tapping
Hose can pull out, be inserted into epidural catheter.Its advantage is easy to operate, reduces pollution probability, can control cerebrospinal fluid flow velocity, when
When monitor cerebrospinal pressure.Its shortcoming 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 ", is worn in common waist
The lumbar puncture needle of medical pressure sensor automatic detection of brain Ridge fluid pressure is utilized on the basis of needle, including needle tubing, needle stand, needle core, three
Logical drainage tube, semiconductor gauge, data call wire form, and a three-way drainage tube and two are designed on the needle stand of puncture needle
Hole, side opening are pressure sensing port, and straight hole is conduction hole.The semiconductor gauge of cerebrospinal fluid and side opening when passing through three-way drainage tube
Connect, after foil gauge induction pressure signal, bio signal is passed to by electron pressure detector, electron pressure detection by data line
Equipped with signal amplification module and conversion module in device, bio signal is converted into digital signal and is shown.Its advantage is can be
Pressure is measured before drainage of cerebrospinal fluid, is only just drained when cerebrospinal pressure is safe, it is safer.Shortcoming 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 splashes.
