Abstract
The utility model relates to a medical device and discloses a lumbar puncture needle comprising a puncture needle and a puncture needle inner core. The lumbar puncture needle is characterized in that the tail end of the puncture needle is fixedly connected with a Y-section; a cross-opened elastic fracture cap is arranged at the rear part of the Y-section; a pressure measuring valve is fixedly connected with the Y-section; and the puncture needle inner core penetrates the puncture needle through the cross-opened elastic fracture cap of the Y-section. During puncture, the puncture needle inner core is drawn out when the needle point enters the endorachis cavity, and the cross-opened elastic fracture cap of the Y-section automatically shrinks and is closed when the puncture needle inner core is drawn out of the puncture needle, so as to effectively prevent pollution and potential hazards of cerebral hernia caused by jet type overflow of cerebrospinal fluid due to the pressure difference around the puncture needle when the puncture needle inner core is drawn out, avoid the running out and loss of cerebrospinal fluid, and avoid cerebral hernia caused by quick release of cerebrospinal fluid resulted from over-high intracranial pressure. The release rate of the cerebrospinal fluid can be adjusted within certain range through controlling the pressure measuring valve, so as to effectively prevent cerebral hernia.
Description
Technical field
This utility model relates to a kind of medical equipment, is a kind of lumbar puncture needle.
Background technology
Existing lumbar puncture needle only has lumbar puncture needle and inner core, extracts out when inner core, and it is excessive that the cerebrospinal fluid that puncture needle sleeve pipe left and right sides pressure at two ends difference causes is spurting, pollutes and exist the danger that cerebral hernia takes place easily.The excessive back of cerebrospinal fluid is measured cerebrospinal fluid first pressing meeting and is slightly reduced, and causes the pressure measurement inaccuracy.
Summary of the invention
The purpose of this utility model is, prior art is improved, and provides a kind of and can accurately measure intracranial pressure, and can effectively avoid the lumbar puncture needle that takes place because of cerebrospinal fluid outflow causing intracranial infection and cerebral hernia.
The purpose of this utility model is realized by following technical scheme: a kind of lumbar puncture needle, it comprises lumbar puncture needle and lumbar puncture needle inner core, it is characterized in that: the tail end and the tee pipe coupling of described lumbar puncture needle are connected, be provided with cross opening elasticity crack medicated cap at the rear portion of tee pipe coupling, being connected in tee pipe coupling is connected to the pressure valve door, and the lumbar puncture needle inner core is threaded onto in the lumbar puncture needle by the cross opening elasticity crack medicated cap of tee pipe coupling.
A kind of lumbar puncture needle of the present utility model, owing to be provided with cross opening elasticity crack medicated cap at the rear portion of tee pipe coupling, in tee pipe coupling, be connected and be connected to the pressure valve door, the cross opening elasticity crack medicated cap of lumbar puncture needle inner core by tee pipe coupling is threaded onto the structure in the lumbar puncture needle, after entering the spinal dura mater chamber, extracts at needle point the lumbar puncture needle inner core during puncture, the lumbar puncture needle inner core is extracted the back tee pipe coupling out in lumbar puncture needle cross opening elasticity crack medicated cap shrinks closure automatically, can effectively prevent to extract out because of the lumbar puncture needle inner core, it is excessive that the cerebrospinal fluid that pressure reduction causes around the lumbar puncture needle is spurting, pollute and danger that cerebral hernia takes place, prevent that cerebrospinal fluid from flowing out and losing, prevent that because of the intracranial pressure height cerebrospinal fluid runs off fast and produces the possibility of cerebral hernia; The pressure measurement valve of tee pipe coupling is connected with pressure-measuring pipe, but the rate of release of control pressure measurement valve appropriate regulation cerebrospinal fluid can effectively prevent the generation of cerebral hernia.
Description of drawings
Fig. 1 is a kind of lumbar puncture needle structural representation.
Fig. 2 is that lumbar puncture needle inner core 1 is extracted view out.
Fig. 3 is an A-A cross-sectional schematic among Fig. 2.
Among the figure: 1 lumbar puncture needle inner core, 2 pressure measurement valves, 3 tee pipe couplings, 4 lumbar puncture needles, 5 cross opening elasticity crack medicated caps.
The specific embodiment
The utility model is described in further detail to utilize drawings and Examples below.
With reference to Fig. 1-3, a kind of lumbar puncture needle of the present utility model comprises lumbar puncture needle 4 and lumbar puncture needle inner core 1, the tail end of described lumbar puncture needle 4 and tee pipe coupling 3 are connected, be provided with cross opening elasticity crack medicated cap 5 at the rear portion of tee pipe coupling 3, being connected in tee pipe coupling 3 is connected to pressure valve door 2, and lumbar puncture needle inner core 1 is threaded onto in the lumbar puncture needle 4 by the cross opening elasticity crack medicated cap 5 of tee pipe coupling 3.Tee pipe coupling 3 and cross opening elasticity crack medicated cap 5 adopt vulcanie or rubber-plastics material mould molding.Pressure measurement valve 2 is the commercially available prod.
