Summary of the invention:
The purpose of this utility model is to overcome the shortcoming existing in prior art, provide a kind of simple in structure, easy to use, once measuring pressure and sampling operation can be completed, and the sealing of censorship process, a kind of Neurology Department cerebrospinal fluid specimen sampler of avoiding samples of CSF to pollute.
To achieve these goals, this utility model provides a kind of Neurology Department cerebrospinal fluid specimen sampler, comprise specimen tube, plastic tube and flexible pipe, one side of plastic tube is plugged and connected with Pressure gauge, flexible pipe one end is plugged and connected with puncture needle, between the other end of flexible pipe and the upper end of plastic tube, plug together and be connected, the integrated graduation mark that is provided with on the tube wall of specimen tube, wherein, the top of specimen tube is provided with upper cover, the bottom of specimen tube is provided with lower cover, the middle part of upper cover is provided with inlet, between the lower end of plastic tube and inlet, be threaded, between lower cover and specimen tube, be threaded, one side of specimen tube is provided with adhesive tape, between one end of adhesive tape and the outer wall of specimen tube, be adhesively fixed, the integrated sealing-plug that is provided with of the other end of adhesive tape, sealing-plug can and inlet between peg graft fixing, specimen tube and upper cover are one-body molded during fabrication.
The bottom of described specimen tube is provided with guide cone, guide cone is funnel-form, the bottom of guide cone is provided with discharging tube, on discharging tube, be provided with switch, guide cone, discharging tube and specimen tube are one-body molded during fabrication, between lower cover and specimen tube, are threaded, and described switch is for controlling the unlatching of discharging tube or cutting out.
On described flexible pipe, be provided with to compress and buckle, compression retaining ring is connected on the outside of flexible pipe.Compress button for opening or closing flexible pipe, be beneficial to Pressure gauge detected pressures.(compressing button is the device of the control flow on stilligout, and it is made up of cell body and pulley, and flexible pipe passes cell body and pushed down by pulley, and the cross section of cell body is trapezoidal, sealing or the unlatching of the scrolling realization flexible pipe by pulley on cell body)
Each of conduit, plastic tube, specimen tube plugs together junction and can further be provided with sealing joint strip or sealing member, connects for watertightness.
Advantage of the present utility model is, simple in structure, easy to use, once measuring pressure and sampling operation can be completed, and the sealing of censorship process, avoid samples of CSF to pollute.Be specially:
1, Pressure gauge is integrated on the plastic tube of hard, after puncture needle thrusts, observes pressure by Pressure gauge, during to desired value, opens flexible pipe, utilizes the negative pressure in specimen tube to derive spinal fluid, and disposable completing observed pressure and the operation that imports sample, without distributed operation
2, after sampling, screw off plastic tube, by sealing-plug jam-pack inlet, (before censorship, discharging tube is sealed by switch, and lower cover is screwed on specimen tube in censorship.
3,, when specimen is taken out, the lower cover of outwarding winding, opens switch, and spinal fluid in-line arrangement liquid bank of tubes is gone out.In whole process, inlet and leakage fluid dram all seal, and are conducive to the intact preservation of specimen.
