Description
Technical field
The invention belongs to medical appliance fields, and in particular to one kind can survey the therapeutic type of oxygen partial pressure of cerebrospinal fluid and biochemical indicator
Lumbar puncture needle.
Background technique
Lumbar puncture is that Neurology one of commonly operates, and is mainly used for extracting cerebrospinal fluid measurement pressure, to arachnoid
Cavity of resorption injection of medicine, cerebrospinal fluid radiography leave and take samples of CSF etc., clinically take the mode of cerebrospinal fluid usual are as follows: Huan Zhetong
Often it is lateral position of bending over, implements to puncture from waist 2 to (based on the waist 3-4) intervertenral space of sacrum 1.After local routine disinfection and anesthesia, wear
Rubber gloves, puncture needle are slowly pierced into along spinous process direction and perpendicular to back flat, when needle point encounters sclerotin during inserting needle, answer
Needle is retreated to and is subcutaneously punctured again after correcting angle.When adult inserting needle about 4-6cm (children about 3-4cm), it can wear out hard
Spinal meninges and reach spider film chamber off the net, whether extraction section seal wire, observation cerebrospinal fluid flows out, and slow tapping (is no more than 2-3ml).Art
Finish, lumbar puncture needle of the invention is extracted, cover antiseptic gauze, with immobilization with adhesive tape, patient goes pillow prostrate 4-6 hours, later
The cerebrospinal fluid of acquisition is used to measure all kinds of biochemical indicators.
Oxygen partial pressure of cerebrospinal fluid refers to the strength of physical dissolution oxygen in cerebrospinal fluid, reflects the degree of cerebral anoxia, equally
It is one of the important detection index of cerebrospinal fluid.But cerebrospinal fluid used at present adopts liquid device or the structure design of liquid trap exists very
More defects: the exposure for a long time of 1. cerebrospinal fluid in the environment, is easy the pollution by allogenic material；2. since air atmosphere pressure is greater than
Cerebrospinal pressure, so oxygen, the carbon dioxide etc. in air can be pressed into cerebrospinal fluid by atmospheric pressure while ingress of air,
So that the measurement numerical value inaccuracy of oxygen partial pressure of cerebrospinal fluid, the diagnostic result for causing doctor that must make mistake, to influence subsequent control
It treats.Therefore, measurement oxygen partial pressure of cerebrospinal fluid is not particularly suited for using the cerebrospinal fluid that traditional lumbar puncture needle is collected.
In addition, researcher attempts the structure of improvement lumbar puncture needle, but still have some other defects:
For example, patent of invention " a kind of lumbar puncture needle " (patent No. CN201210568499.7), can be used for measuring brain ridge
Hydraulic coupling and injection drug, the device secure the needle on handle, pass through transparent handle or the setting observation of handle official jargon position
Window observes whether cerebrospinal fluid flows out；After syringe needle enters human body, rotation by valve handle threaded rod relative to handle threads through-hole,
Realize drainage, the accurate discharge for controlling cerebrospinal fluid.There is no solve following defect possessed by traditional puncture needle for the device: 1.
The depth of insertion is grasped in inconvenience, and usual doctor acquires cerebrospinal fluid by experience；2. largely can without isolation air assembly
A large amount of oxygen, the composition of air such as carbon dioxide are mixed into, so that the partial pressure of oxygen measured and other biochemical indicator related datas exist
Very big error；3. pressure measuring unit is directly contacted with cerebrospinal fluid, Reusability will cause pollution and measurement result is inaccurate.
And utility model patent " lumbar puncture needle " (patent No. CN201220508634.4), it can be used in measuring cerebrospinal fluid
Pressure, the device include puncturing needle tubing and being located at the needle stand for puncturing syringe rear end, and the scale punctured on needle tubing can accurately be sentenced
The disconnected depth punctured；There is no solve following defect possessed by traditional puncture needle for the device: whether 1. lacking observation cerebrospinal fluid
The intuitive visuality of outflow；2. can largely be mixed into a large amount of oxygen, the air such as carbon dioxide without isolation air assembly
Ingredient, so that the partial pressure of oxygen measured and the related data of other biochemical indicators have very big error；3. pressure measuring unit and brain ridge
Liquid directly contacts, and Reusability will cause pollution and measurement result is inaccurate；4. purposes is single, without can not only acquire cerebrospinal fluid but also
It can be used for changing liquid or inject the function of drug.
However, not being exclusively used in collecting cerebrospinal fluid at present on the market, the cerebrospinal fluid being collected into is made to keep the waist of original state
Vertebra puncture needle guarantees the accuracy of every Determination of Physiological And Biochemical Indices result, it is difficult to meet the needs of medical diagnosis and treat and market, because
This, there is an urgent need to a kind of new devices, to meet above-mentioned requirements.
Summary of the invention
The present invention provides a kind of lumbar puncture needle that can be solved the above problems, i.e., lumbar puncture needle according to the present invention can
Whether directly observation cerebrospinal fluid flows out, and energy accurate perception paracentesis depth can collect cerebrospinal fluid in closed environment, accurate to control
The amount of cerebrospinal fluid processed；Also cerebrospinal pressure can be sensed by special substance seal wire, be subsequent by observing the size of its pressure
Clinic diagnosis provides guidance.The lumbar puncture needle is easy to operate, easy to use, is mainly used for adopting in the case where guaranteeing safety
Collection by the cerebrospinal fluid of air pollution, does not make collected cerebrospinal fluid keep original state, realizes oxygen partial pressure of cerebrospinal fluid and other lifes
