Description
Technical field
This utility model relates to technical field of medical instruments, and relating in particular to is the lumbar puncture sampler that a kind of B ultrasonic is assisted, and is mainly used in the sampling work up of cerebrospinal fluid in lumbar puncture.
Background technology
In the checkout and diagnosis of clinical cerebrospinal fluid, lumbar puncture is the biopsy sampling mode relatively commonly used, existing aspiration biopsy sampling process needs two people to operate simultaneously, one people uses Ultrasonic-B probe to detect concrete puncture position, puncture procedure is carried out after labelling, then need to use syringe to extract, CSF sample is squeezed in the probe tube that an other people opens.This sampling method needs two people's precise match, and hight coordinate unanimously just can complete whole sampling process.This mode has drawback, and one is have certain error after the artificial demarcation in B ultrasonic location, easily causes location to occur deviation, causes puncture failure.Second be B ultrasonic location after lancet puncture time cannot fix, cause puncture position produce skew.Cause operate miss.3rd is that two medical operator coordinated manipulations easily produce careless omission, causes sample to leak and spreads, there is the risk of pathophoresis.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides the lumbar puncture sampler that a kind of B ultrasonic is auxiliary.
A technical scheme of the present utility model is:
The lumbar puncture sampler that a kind of B ultrasonic is auxiliary, comprise Ultrasonic-B probe 1, puncture needle 2, puncture needle core 3, conduction hose 4, pressure sensing display 5, drainage needle 6, sampling below atmospheric pressure pipe 7 and vacuum pump 8, described puncture needle 2 is provided with set bolt 9, described conduction hose 4 is provided with pressure switch 10 and drain switch 11, described sampling below atmospheric pressure pipe 7 is provided with graduation mark 12, described vacuum pump 8 is provided with vacuum and takes out pipe 13, described puncture needle 2 runs through vertical and inserts in Ultrasonic-B probe 1, be fixed in Ultrasonic-B probe 1 by set bolt 9, puncture needle core 3 is inserted with in puncture needle 2, puncture needle 2 end removably connects to conduction hose 4, conduction hose 4 is successively by drain switch 11, drainage needle 6 is connected to sampling below atmospheric pressure pipe 7, conduction hose 4 is connected to pressure sensing display 5 by pressure switch 10, sampling below atmospheric pressure pipe 7 is taken out pipe 13 by vacuum and is connected to vacuum pump 8.
This utility model tool has the following advantages: 1, puncture needle is fixed in Ultrasonic-B probe, can, accurately while localised puncture position, play fixation, carry out puncture procedure more accurately to puncture needle itself; 2, after having punctured, open corresponding pressure switch can show cerebrospinal fluid clearly concrete force value by pressure sensing display, operate more intuitively easy; 3, sampling below atmospheric pressure pipe is connected on puncture needle by conduction hose is closed, directly sample is extracted out by the negative pressure in probe tube, simple and convenient; 4, in sampling below atmospheric pressure pipe, negative pressure can carry out real-time adjustment by vacuum pump, negative pressure requirements when meeting different sampling in probe tube, 5, negative-pressure sealed systematic sampling simplifies the operation flow process, one man operation, avoid the possibility of spreading outside sample, reduce sampling risk.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lumbar puncture sampler of this utility model.
Wherein: 1 is Ultrasonic-B probe; 2 is puncture needle; 3 is puncture needle core; 4 is conduction hose; 5 is pressure sensing display; 6 is drainage needle; 7 is sampling below atmospheric pressure pipe; 8 is vacuum pump; 9 is set bolt; 10 is pressure switch; 11 is drain switch; 12 is graduation mark; 13 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, the lumbar puncture sampler that a kind of B ultrasonic of the present utility model is auxiliary, comprise Ultrasonic-B probe 1, puncture needle 2, puncture needle core 3, conduction hose 4, pressure sensing display 5, drainage needle 6, sampling below atmospheric pressure pipe 7 and vacuum pump 8, described puncture needle 2 is provided with set bolt 9, described conduction hose 4 is provided with pressure switch 10 and drain switch 11, described sampling below atmospheric pressure pipe 7 is provided with graduation mark 12, described vacuum pump 8 is provided with vacuum and takes out pipe 13, described puncture needle 2 runs through vertical and inserts in Ultrasonic-B probe 1, be fixed in Ultrasonic-B probe 1 by set bolt 9, puncture needle core 3 is inserted with in puncture needle 2, puncture needle 2 end removably connects to conduction hose 4, conduction hose 4 is successively by drain switch 11, drainage needle 6 is connected to sampling below atmospheric pressure pipe 7, conduction hose 4 is connected to pressure sensing display 5 by pressure switch 10, sampling below atmospheric pressure pipe 7 is taken out pipe 13 by vacuum and is connected to vacuum pump 8.
During operation, first puncture needle 2 and conduction hose 4 are taken apart, then the puncture needle 2 with puncture needle core 3 is fixed in Ultrasonic-B probe 1 by set bolt 8, after being located by Ultrasonic-B probe 1, carry out puncture procedure.Extract puncture needle core 3 from puncture needle 2 end after having punctured, then puncture needle 2 end is connected with conduction hose 4.First open pressure switch 10, pressure sensing display 5 will show current cerebrospinal pressure force value, for clinical diagnosis.First by vacuum pump 8, sampling below atmospheric pressure pipe 7 is evacuated to sampling requirement vacuum during sampling, is then opened by drain switch 11, CSF sample gets final product suction to sampling below atmospheric pressure pipe 7, when sampling amount reaches scale requirement, close drain switch 11, sampling below atmospheric pressure pipe 7 extracted from drainage needle 6.
The lumbar puncture sampler that B ultrasonic described above is assisted is simple and convenient, decreases the operation easier of health care worker, reduces sampling risk.
