Abstract
The utility model discloses a kind of medical inspection section anti-suck blood sampler, comprise sampler main body, flexible catheter and inspection test tube, described sampler main body is made up of sampling probe, piston and boosting bar, described boosting bar one end is fixedly connected with piston and is placed in sampler main body, and described boosting bar opposite side is provided with boosting block, described sampler main body one end is connected with flexible catheter one end by air filtration valve, the described flexible catheter other end is connected with sampling probe by check valve, is connected with inspection test tube in the middle part of described flexible catheter.This kind of medical inspection section anti-suck blood sampler, by installing air filtration valve and check valve respectively at flexible catheter two ends, avoid the backflow of blood phenomenon of medical worker when sampling blood to patient, reduce patient suffering, simultaneously because this device is when sampling blood, blood touches outside air hardly, make the blood sampled not by bacteriological infection, improve the accuracy of assay, compact conformation, be easy to realize.
Description
Technical field
This utility model relates to a kind of medical blood sampler, is specially a kind of medical inspection section anti-suck blood sampler, belongs to medical inspection section equipment technical field.
Background technology
At present, in Clinical Laboratory, frequent collection blood is tested, generally test with in blood taking needle extraction blood then injecting tube, due in the process extracting blood, extraction speed is slow, be easy to occur blood suck-back phenomenon, make patient sample blood position swelling pain, have a strong impact on sample rate, and make patient more painful, sample blood in addition like this can cruelly leak in atmosphere, antibacterial easily enters blood, and blood is apt to deteriorate, cause assay inaccurate, add inspection work difficulty to medical worker.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, a kind of medical inspection section anti-suck blood sampler is provided, by installing air filtration valve and check valve respectively at flexible catheter two ends, avoid the backflow of blood phenomenon of medical worker when sampling blood to patient, thus solve the problem.
For achieving the above object, this utility model provides following technical scheme: a kind of medical inspection section anti-suck blood sampler, comprise sampler main body, flexible catheter and inspection test tube, described sampler main body is by sampling probe, piston and boosting bar composition, described boosting bar one end is fixedly connected with piston and is placed in sampler main body, and described boosting bar opposite side is provided with boosting block, described sampler main body one end is connected with flexible catheter one end by air filtration valve, the described flexible catheter other end is connected with sampling probe by check valve, inspection test tube is connected with in the middle part of described flexible catheter.
Further, described inspection test tube is by being connected described flexible catheter with the test tube plug that inspection test tube matches.
Further, described piston and sampler main body match, and are quality of rubber materials.
Further, described sampler body surfaces is provided with volume markings.
Compared with prior art, the beneficial effects of the utility model are: this kind of medical inspection section anti-suck blood sampler, by installing air filtration valve and check valve respectively at flexible catheter two ends, avoiding the backflow of blood phenomenon of medical worker when sampling blood to patient, reducing patient suffering, simultaneously because this device is when sampling blood, blood touches outside air hardly, makes the blood sampled not by bacteriological infection, improves the accuracy of assay, compact conformation, is easy to realize.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for description, is used from explanation this utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of medical inspection section described in the utility model anti-suck blood sampler structural representation;
Fig. 2 is a kind of medical inspection section described in the utility model anti-suck blood sampler partial enlarged drawing;
In figure: 1, sampling probe; 2, check valve; 3, flexible catheter; 4, air filtration valve; 5, sampler main body; 6, boosting block; 7, piston; 8, test tube plug; 9, test tube is checked; 10, boosting bar.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment; technical scheme in this utility model embodiment is clearly and completely described; obviously; described embodiment is only this utility model part embodiment; instead of whole embodiments; based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of medical inspection section anti-suck blood sampler, comprise sampler main body 5, flexible catheter 3 and inspection test tube 9, described sampler main body 5 is by sampling probe 1, piston 7 and boosting bar 10 form, described boosting bar 10 one end is fixedly connected with piston 7 and is placed in sampler main body 5, and described boosting bar 10 opposite side is provided with boosting block 6, described sampler main body 5 one end is connected with flexible catheter 3 one end by air filtration valve 4, described flexible catheter 3 other end is connected with sampling probe 1 by check valve 2, inspection test tube 9 is connected with in the middle part of described flexible catheter 3.
Described inspection test tube 9 is by being connected described flexible catheter 3 with the test tube plug 8 that inspection test tube 9 matches, inspection test tube 9 and flexible catheter 3 is connected by test tube plug 8, guarantee the air-tightness of this device, make this device when sampling blood to patient, the blood sampled out by external environmental, can not improve the accuracy of assay.Described piston 7 and sampler main body 5 match, and are quality of rubber materials, to be matched absorption, effectively can extract blood to patient by piston 7 pairs of sampler main bodys 5.Described sampler main body 5 surface is provided with volume markings, can be observed by volume markings the volume sampling blood, avoids few sampling and many samplings to cause secondary injury to patient.
It should be noted that, when medical worker samples blood samples of patients, sampling probe 1 is inserted in Venous Blood liquid, open check valve 2 now check valve 2 control direction of the traffic, air filtration valve 4 controls the pressure of sampler main body 5, avoid backflow of blood phenomenon, medical worker slowly extracts boosting bar 10 by boosting block 6, blood sky is crossed check valve 2 and is flowed out, flow through in sampler main body 5 through flexible catheter 3, then closing one-way valve 2, the blood in sampler main body 5 is advanced in inspection test tube 9 by boosting bar 10.
To those skilled in the art, obvious this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or basic feature, can realize this utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in this utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present utility model; not in order to limit this utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
