Abstract
This utility model relates to a kind of bone marrow aspiration sampler.Comprise puncture needle (1), puncture needle core (2), conduction hose (3), drainage needle (4), sampling below atmospheric pressure pipe (5) and vacuum pump (6), described conduction hose (3) is provided with drain switch (7), described sampling below atmospheric pressure pipe (5) is provided with graduation mark (8), described vacuum pump (6) is provided with vacuum and takes out pipe (9), this utility model is rational in infrastructure, easy and simple to handle, decrease the operation easier of health care worker, reduce sampling risk.
Description
Technical field
This utility model relates to technical field of medical instruments, and relating in particular to is a kind of bone marrow aspiration sampler of novel band sampling below atmospheric pressure pipe, is mainly used in the sampling work up of disease in the blood system.
Background technology
In the clinical diagnosis of blood system, puncture needle is the most frequently used apparatus in biopsy technique, existing aspiration biopsy sampling process needs two people to operate simultaneously, and a people uses syringe to extract, and is then squeezed into by sample of bone marrow 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.
There are two drawbacks in current biopsy sampling technique, a negative pressure being syringe itself needs outer power to produce carrys out bone marrow extraction sample, extracts comparatively difficulty.Second 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 a kind of novel bone marrow aspiration sampler.
A technical scheme of the present utility model is:
A kind of bone marrow aspiration sampler, comprise puncture needle 1, puncture needle core 2, conduction hose 3, drainage needle 4, sampling below atmospheric pressure pipe 5 and vacuum pump 6, described conduction hose 3 is provided with drain switch 7, described sampling below atmospheric pressure pipe 5 is provided with graduation mark 8, described vacuum pump 6 is provided with vacuum and takes out pipe 9, 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 connected to sampling below atmospheric pressure pipe 5 by drainage needle 4, sampling below atmospheric pressure pipe 5 is taken out pipe 9 by vacuum and is connected to vacuum pump 6, in described sampling below atmospheric pressure pipe 5, negative pressure is at-0.03 ~-0.1mpa, described graduation mark 8 graticule scope is 1 ~ 5ml.
This utility model tool has the following advantages: 1, closed by conduction hose by sampling below atmospheric pressure pipe and be connected on puncture needle, directly extracted out by sample by the negative pressure in probe tube, simple and convenient; 2, repeatedly sampling only by closing drain switch, need change sampling below atmospheric pressure pipe.Also accurately can control sampling amount simultaneously; 3, 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, 4, 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 bone marrow aspiration sampler of this utility model.
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 drain switch; 8 is graduation mark; 9 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 bone marrow aspiration sampler of the present utility model, comprise puncture needle 1, puncture needle core 2, conduction hose 3, drainage needle 4, sampling below atmospheric pressure pipe 5 and vacuum pump 6, described conduction hose 3 is provided with drain switch 7, described sampling below atmospheric pressure pipe 5 is provided with graduation mark 8, described vacuum pump 6 is provided with vacuum and takes out pipe 9, 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 connected to sampling below atmospheric pressure pipe 5 by drainage needle 4, sampling below atmospheric pressure pipe 5 is taken out pipe 9 by vacuum and is connected to vacuum pump 6, in described sampling below atmospheric pressure pipe 5, negative pressure is at-0.03 ~-0.1mpa, described graduation mark 8 graticule scope is 1 ~ 5ml.
During sampling, first puncture needle 1 and conduction hose 3 are taken apart, when the puncture needle 1 with puncture needle core 2 inserts after in bone marrow through skin, extract puncture needle core 2 from its end, then puncture needle 1 end is connected with conduction hose 3, by vacuum pump 6, sampling below atmospheric pressure pipe 5 is evacuated to sampling requirement vacuum, is then opened by drain switch 6, sample of bone marrow gets final product suction to sampling below atmospheric pressure pipe 5, when sampling amount reaches scale requirement, close drain switch 6, sampling below atmospheric pressure pipe 5 extracted from drainage needle 4.
Bone marrow aspiration sampler described above is simple and convenient, decreases the operation easier of health care worker, reduces sampling risk.
