Abstract
A nanometric type lumbar puncture outfit is used for clinic measuring the encephalic pressure of patients. The device comprises a sacculus, a transparent manometer tube integrated with the sacculus with engraved lines of millimeter water column, an embolism valve which is arranged on the shoulder of the sacculus, and a hollow rob-typed pricker connected with the head of the manometer tube. The pricker causes no loss of cerebrospinal fluid. The value of the encephalic pressure can be accurately read out from the scale of the millimeter water column of the manometer tube. The cerebrospinal fluid also can be used as sampling and be submitted in for laboratory tests. The operation of the device is simple, and is for one-time use only so as to avoid the repeated use which leads to the cross contamination. The cost of the device is low and can be popularly used.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of pressure measurement formula lumbar puncture outfit that is used to measure intracranial pressure and collection samples of CSF censorship chemical examination.
Background technology
In the prior art, clinically be used to measure intracranial pressure lumbar puncture apparatus and have two kinds.A kind of is the puncture needle of band pin stamen, feel with the operator during puncture judges whether to enter subarachnoid space, extract the pin stamen then out, collect spinal fluid, when surveying intracranial pressure as if needs with test tube, need connect " L " type pressure-measuring pipe of one millimeter of water graduation mark in addition, the pressure measurement scope is little, and the patient's of running off easily cerebrospinal fluid causes patient's intracranial hypotension headache, severe complications such as cerebral hernia, threat to life sometimes; Another kind is " a multi-functional lumbar vertebra puncture apparatus ", adopt pressure receptor, pressure signal is transformed into the signal of telecommunication to be shown with numeral, this instrument cost height, complicated operation, it produces error with the variation of electric current, voltage, because the electronic component variation of parameter in use causes pressure measurement inaccurate sometimes, be difficult for popularizing again.If when needing to collect the cerebrospinal fluid censorship, also be easy to generate pollution.
The purpose of this utility model is to provide a kind of pressure measurement accurate, simple to operate to people, and collection and the censorship standard of being convenient to cerebrospinal fluid are not contaminated, avoid cross infection, cheap pressure measurement formula lumbar puncture outfit.
Summary of the invention
This utility model is realized by following proposal.
Pressure measurement formula lumbar puncture outfit, it comprises that needle section has the shaft-like puncture needle of shaft-like puncture of the hollow of side opening, be characterized in: it also comprises a sacculus, that communicate with it and the integrant transparent pressure-measuring pipe that is carved with millimeter of water graduation mark are arranged on the sacculus, the termination of pressure-measuring pipe and shaft-like puncture needle combine, and the pore of transparent pressure-measuring pipe is made of one section straight hole and one section taper hole of communicating.The shoulder of sacculus has and communicates with sacculus and become integrally-built thromboembolism valve.Pressure-measuring pipe, sacculus, thromboembolism valve adopt medical polyvinyl to make, and adopt the mould single injection-molded.
Millimeter of water graduation mark on the transparent pressure-measuring pipe is according to glass horse law, the volume of closed gas and the proportionate relationship of pressure, the millimeter of water graduation mark that experiment draws under the standard state condition.The pressure measurement big more, that be carved with millimeter of water graduation mark of the volume of sacculus is long more, and graduation mark becomes to be dredged, and then shows accurate more.For the ease of operation, the volume of sacculus is designed to 15～20 milliliters.
Pressure measurement formula lumbar puncture outfit, when carrying out puncture pressure measuring clinically, the puncture back is if there is fluid column to occur in the transparent pressure-measuring pipe pore, show and puncture successfully, cerebrospinal fluid liquid form with fluid column in the pressure-measuring pipe pore occurs, cerebrospinal fluid does not run off, can accurately on the pressure-measuring pipe and millimeter of water graduation mark on read intracranial pressure the millimeter of water, directly show intracranial pressure, when needs samplings (specimen) censorship chemical examination, as long as open the thromboembolism valve, the sacculus internal pressure is discharged, cerebrospinal fluid just flows in the sacculus from side pressure pipe pore, closes the thromboembolism valve when reaching requirement, can inspect chemical examination by ready samples behind the dial-out puncture needle.It only does disposable use, has avoided reusing and the cross infection of generation, and Song Jian specimen is not contaminated yet simultaneously.This utility model is cheap, popularizes easily.
Description of drawings
Below in conjunction with embodiment and accompanying drawing in detail this utility model is described in detail.
Fig. 1 is the structure chart of this utility model embodiment 1.
Fig. 2 is that this utility model embodiment 2 has structure chart.
Fig. 3 is that complete section figure is amplified in 1 part among Fig. 2.
Embodiment
Embodiment 1: in the embodiment shown in fig. 1, it comprise needle section have the hollow of side opening 6 shaft-like puncture needle 5, it comprises that a volume is to have on 15～20 milliliters the sacculus 1, sacculus 1 to communicate with it and the integrant transparent pressure-measuring pipe 3 that is carved with millimeter of water graduation mark, the shaft-like puncture needle 5 of the termination of pressure-measuring pipe 3 and hollow combines, the pore of transparent pressure-measuring pipe is straight hole section 4 that communicates with puncture needle and the taper hole section 2 that communicates with sacculus 1, the pore diameter of straight hole section is 1.8～2.2 millimeters, is the best with 2.0 millimeters.The shoulder of sacculus 1 has that communicate with sacculus 1 and constitutes integrally-built thromboembolism valve 7 with sacculus 1.
Embodiment 2: in the embodiment shown in Figure 2, sacculus 1, pressure-measuring pipe 2, the shaft-like cold valve 7 of puncture needle 5, bolt are identical with the structure of embodiment shown in Figure 1, different is, for injectable drug, puncture needle 5 adopts plug in construction with being connected of pressure-measuring pipe 2, i.e. the end shape of pressure-measuring pipe 2 design has the pipe joint of being convenient to insert with puncture needle 58.
Claims (2)
1, a kind of pressure measurement formula lumbar puncture outfit, it comprises that needle section has the shaft-like hole of threading a needle (5) of the hollow of side opening (6), it is characterized in that: it also is included as the sacculus (1) of a transparent body, the transparent pressure-measuring pipe (3) that millimeter of water graduation mark that communicate with it and integrant quarter is arranged on the sacculus (1), the pore of transparent pressure-measuring pipe (3) is made of the one section straight hole (4) that communicates and one section taper hole (2), the pore diameter of diameter segment is 1.8～2.2 millimeters, the shoulder of sacculus (1) has and communicates with sacculus (1) and become integrally-built thromboembolism valve (7), and the termination portion of pressure-measuring pipe (3) is connected with puncture needle (5).
2, a kind of pressure measurement formula waist awl perforator according to claim 1, its feature also is: there is the plug connector (8) that cooperates with puncture needle in pressure-measuring pipe (3) termination portion.
