Technical field
This utility model belongs to medical apparatus, and specifically a kind of patient who suffers from pathological changes for the suspection brain measures intracranial pressure and leaves and takes the device that CSF sample is chemically examined.
Background technology
In order to diagnose and dynamic observe patient's the state of an illness,, often need take out cerebrospinal fluid and chemically examine and measure intracranial pressure by the lumbar puncture art so that formulate the proper treatment scheme.At present be, be docked at the lumbar puncture needle syringe needle with the transverse tube of transparent special use " L " shape pipe and export, on the vertical tube tube wall of " L " shape pipe, indicate the graduation mark that can show fluid pressure cerebrospinal fluid sampling and the mode of surveying intracranial pressure.During operation, usually lumbar puncture needle is inserted into the subarachnoid space of canalis spinalis through lumbar vertebra the 3rd or 4 or 5 intervertebral spaces, outwards pull out the drain core in the puncture needle tubing then, as seen cerebrospinal fluid oozes from the puncture needle mouth, this moment earlier rapidly with the transverse tube of " L " shape pipe to exporting at syringe needle, cerebrospinal fluid then rises to vertical tube along " L " shape pipe, and the scale from the vertical tube tube wall can be read intracranial pressure; Side pressure finishes " L " shape pipe is removed from piercing needle, promptly can leave and take a small amount of cerebrospinal fluid lentamente to chemically examine from the syringe needle exit.
Normal person's intracranial pressure is generally 80---180 millimeters of water.At present, the vertical tube scale of " L " shape pipe has only 300mm, use for the patient of intracranial pressure below 300 millimeter of water pressure with said method, be open (the standard side pressure is desired) because of the vertical tube of " L " shape pipe is suitable for reading again, and the state of an illness reaches more than 400 millimeters of water than frequent 300 millimeters of water that surpass of heavy patient's intracranial pressure, cerebrospinal fluid can overflow from vertical tube is suitable for reading when pressure was excessive, cerebrospinal fluid oozes but outflow fast by the puncture needle mouth is non-because of pressure is excessive after removing pressure-measuring pipe in addition, this all can make the pressure of intracranial reduce suddenly, the imbalance of pressure that it is unexpected that decline produced of intracranial pressure can be brought life danger to patient, and this process that just requires whole pressure measurement and leave and take CSF sample preferably has controllability to drawing of cerebrospinal fluid.Therefore above-mentioned pressure measurement mode is absolutely unsafe; Moreover, after overflowing, cerebrospinal fluid also can make proliferation of germs, cause patient's cross infection and contaminated environment.
The utility model content
Technical problem to be solved in the utility model is, overcome prior art and bringing life danger to patient easily when patient that waist wears leaves and takes the cerebrospinal fluid chemical examination and measures intracranial pressure for carrying out, and the send as an envoy to shortcoming of proliferation of germs, contaminated environment of cerebrospinal fluid gusher, a kind of measurement intracranial pressure and cerebrospinal fluid sampler are provided.
In order to solve the problems referred to above that prior art exists, this utility model is to adopt following technical proposals to realize: measurement and sampler comprise: carrying liqs pressure scale line, its transverse tube can be docked at transparent " L " shape pipe in the outlet of lumbar puncture needle syringe needle on its vertical tube, between the transverse tube and syringe needle outlet of " L " shape pipe, be connected with the medical control valve of band sampling arm, the break-make between the outlet of control valve may command syringe needle and " L " shape pipe or the sampling arm.
This utility model also has following technical characterictic:
Described medical control valve is medical three-way valve.
During use, lumbar puncture needle is inserted the position that to get cerebrospinal fluid on the lumbar vertebra, extract the drain core in the piercing needle out, earlier medical control valve is led to vertical tube and the direction Close All that leads to the arm of taking a sample, again the transverse tube butt joint is inserted in the syringe needle outlet, slowly opening medical control valve is communicated with earlier cerebrospinal fluid with vertical tube, read the data of intracranial pressure by the fluid pressure graduation mark, when intracranial pressure will be excessive from vertical tube, when exceeding the fluid pressure graduation mark, close the vertical tube passage rapidly, and then the sampling of slowly opening medical control valve props up tube passage, and cerebrospinal fluid flows out in the sampling arm, can take a sample to do chemical examination and use.
Advantage of the present utility model and ridge utmost point effect are, owing between the outlet of the syringe needle of puncture needle and " L " shape pipe, be connected with the take a sample medical control valve of arm of band, medical control valve can also can be communicated with syringe needle exit passageway Close All respectively with the vertical tube and the sampling arm of carrying liqs pressure scale line respectively.When the passage Close All with syringe needle outlet and " L " shape pipe punctures, patient's brain and this device externally are in the state of complete closed, cerebrospinal fluid can not flow out automatically, intracranial pressure is reduced suddenly bring life danger, can not make proliferation of germs cause patient's cross infection and contaminated environment yet to patient; When the passage slowly opened between medical control valve and vertical tube, cerebrospinal fluid rises along vertical tube, thereby can see the fluid pressure graduation mark that cerebrospinal fluid arrives, and observes patient's intracranial pressure; When the sampling arm of slowly opening medical control valve is got the CSF sample chemical examination, also can control speed and flow that cerebrospinal fluid flows out.This apparatus structure is simple, and medical control valve is a prior art, low price, and whole apparatus cost is cheap, and is safe in utilization, convenient.
