Abstract
This utility model relates to a kind of cerebrospinal pressure and detects sampler.Comprise puncture needle (1), puncture needle core (2), conduction hose (3), drainage needle (4), sampling below atmospheric pressure pipe (5), vacuum pump (6) and pressure sensing display (7), described conduction hose (3) is provided with pressure switch (8) and drain switch (9), described sampling below atmospheric pressure pipe (5) is provided with graduation mark (10), and described vacuum pump (6) is provided with vacuum and takes out pipe (11).This utility model is rational in infrastructure, easy and simple to handle, decreases the operation easier of health care worker, reduces medical matters risk.
Description
Technical field
This utility model relates to technical field of medical instruments, and relating in particular to is that a kind of novel cerebrospinal pressure detects sampler, is mainly used in pressure detecting and the sampling work up of lumbar vertebra cerebrospinal fluid.
Background technology
In clinical diagnosis, lumbar puncture is one of more common operation, be mainly used in the pressure detecting of cerebrospinal fluid, and cerebrospinal fluid sampling biopsy diagnosis, mainly first by insertion correct for puncture needle sampling canalis spinalis position in existing operation, then cut-in pressure testing tube, one adopts drip method: measure a cerebrospinal fluid outflow number within a certain period of time and be used as cerebrospinal pressure detected parameters, another kind is a kind of mercury pressure pipe of access, and the mercury column scale shown by manometer tube is used as cerebrospinal pressure detected parameters.These two kinds of modes, the first operation comparatively bothers, and needs medical worker to determine a numerical value, there is artificial error larger.The display of the second pressure detecting numerical value is not directly perceived, there is artificial deviation of reading yet.Also proceed in sampling test tube after needing medical worker to be extracted out by needle tubing when cerebrospinal fluid samples, operating process is comparatively loaded down with trivial details, also likely causes operate miss and infection risk simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of novel cerebrospinal pressure to detect sampler.
A technical scheme of the present utility model is:
A kind of cerebrospinal pressure detects sampler, it is characterized in that: comprise puncture needle 1, puncture needle core 2, conduction hose 3, drainage needle 4, sampling below atmospheric pressure pipe 5, vacuum pump 6 and pressure sensing display 7, described conduction hose 3 is provided with pressure switch 8 and drain switch 9, described sampling below atmospheric pressure pipe 5 is provided with graduation mark 10, described vacuum pump 6 is provided with vacuum and takes out pipe 11, puncture needle core 2 is inserted with in described puncture needle 1, puncture needle 1 end removably connects to conduction hose 3, conduction hose 3 is successively by drain switch 9, drainage needle 4 is connected to sampling below atmospheric pressure pipe 5, conduction hose 3 is connected to pressure sensing display 7 by pressure switch 8, sampling below atmospheric pressure pipe 5 is taken out pipe 11 by vacuum and is connected to vacuum pump 6.
This utility model, after puncture completes, opens corresponding pressure switch can show cerebrospinal fluid clearly concrete force value by pressure sensing display, operates more intuitively easy.After being connected by probe tube by negative-pressure vacuum pump, the sampling work of direct cerebrospinal fluid can be carried out to lumbar puncture position by negative pressure, the medical matters risk that before avoiding, the repeatable operation of sampling is brought simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of cerebrospinal pressure of this utility model detects sampler.
Wherein: 1 is puncture needle; 2 is puncture needle core; 3 is conduction hose; 4 is drainage needle; 5 is sampling below atmospheric pressure pipe; 6 is vacuum pump; 7 is pressure sensing display; 8 is pressure switch; 9 is drain switch; 10 is graduation mark; 11 take out pipe for vacuum.
Detailed description of the invention
Detailed content of the present utility model and detailed description of the invention thereof is further illustrated below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of cerebrospinal pressure of the present utility model detects sampler, comprise puncture needle 1, puncture needle core 2, conduction hose 3, drainage needle 4, sampling below atmospheric pressure pipe 5, vacuum pump 6 and pressure sensing display 7, described conduction hose 3 is provided with pressure switch 8 and drain switch 9, described sampling below atmospheric pressure pipe 5 is provided with graduation mark 10, described vacuum pump 6 is provided with vacuum and takes out pipe 11, puncture needle core 2 is inserted with in described puncture needle 1, puncture needle 1 end removably connects to conduction hose 3, conduction hose 3 is successively by drain switch 9, drainage needle 4 is connected to sampling below atmospheric pressure pipe 5, conduction hose 3 is connected to pressure sensing display 7 by pressure switch 8, sampling below atmospheric pressure pipe 5 is taken out pipe 11 by vacuum and is connected to vacuum pump 6.
During operation, first puncture needle 1 and conduction hose 3 are taken apart, after the puncture needle 1 with puncture needle core 2 completes puncture procedure, puncture needle core 2 is extracted from its end, then puncture needle 1 end is connected with conduction hose 3, open pressure switch 8, pressure sensing display 7 will show current cerebrospinal pressure force value, for clinical diagnosis.First by vacuum pump 6, sampling below atmospheric pressure pipe 5 is evacuated to sampling requirement vacuum during sampling, is then opened by drain switch 9, CSF sample gets final product suction to sampling below atmospheric pressure pipe 5, when sampling amount reaches scale requirement, close drain switch 9, sampling below atmospheric pressure pipe 5 extracted from drainage needle 4.
It is simple and convenient that cerebrospinal pressure described above detects sampler, decreases the operation easier of health care worker, reduce medical matters risk.
