Compared with the prior art, the blood taking needle for the medical examination has the advantages of being reasonable in design, simple in structure, complete in function, convenient to use and the like, is of a disposable use structure, avoids secondary use, and is low in manufacturing cost and easy to popularize and use.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of medical test blood taking needle simple in structure, easy to use.
Background technology
Need blood taking needle to come blood sample collection in the medical inspection process at present, existing blood taking needle is made up of syringe needle and shank, and syringe needle is located at the head of shank, slidely connects sheath at shank.In blood collection procedure, hospital takes place millions of person-times because human injury's accident that syringe needle ruptures or medical personnel's misoperation causes is annual, and this medical-risk that just causes common blood taking needle to cause can not be lower than the medical-risk of syringe.For preventing that risk from taking place, provide various safety blood taking pins in the market, but still there are a lot of deficiencies in these blood taking needles: first production cost is very high; It two is complex manufacturing; It three is that the quality of production is difficult to guarantee; It four is medical personnel's complex operations; It five is that security function is difficult to guarantee.Thereby it is very necessary how designing a kind of disposable safety blood taking pin.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of medical test blood taking needle simple in structure, easy to use is provided.
The technical solution of the utility model realizes in the following manner, this a kind of medical test blood taking needle, its structure comprises the blood sampling tube of rear end by seal cover sealing, is arranged on the puncture needle of blood sampling tube front end, this blood sampling tube outside is socketed with sleeve, the leading section of described blood sampling tube is arranged in the sleeve, rearward end is stretched out sleeve, between blood sampling tube and sleeve, be provided with slide locating mechanism, between the front end of blood sampling tube and sleeve, be provided with back-moving spring.
As preferably, described detent mechanism comprises L shaped push jack, at least two draw-in grooves that leave the gap and be used with push jack that are symmetricly set on blood sampling tube both sides, with the rectangular triangle of the contacted push jack leading section of draw-in groove.
Further, described barrel forward end is provided with cover.
The beneficial effect that this utility model compared with prior art produces is:
A kind of medical test of the present utility model with blood taking needle have simple in structure, easy to use, characteristics such as be skillfully constructed, design once property use structure, prevent the secondary utilization of blood taking needle, during use only under the situation of pressing puncture needle just can stretch out, avoid its mistake mutual aid system devised for poor peasants to do personnel, the use simple and flexible, cost is with low cost, is easy to promote the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Labelling in the accompanying drawing is represented respectively:
1, blood sampling tube, 2, push jack, 3, draw-in groove, 4, sleeve, 5, puncture needle, 6, cover, 7, back-moving spring, 8, seal cover.
The specific embodiment
Below in conjunction with accompanying drawing a kind of medical test of the present utility model is done following detailed description the in detail with blood taking needle.
As shown in Figure 1, a kind of medical test blood taking needle, its structure comprises blood sampling tube 1, is arranged on the puncture needle 5 of blood sampling tube 1 front end, this blood sampling tube 1 outside is socketed with sleeve 4, the leading section of described blood sampling tube 1 is arranged in the sleeve 4, rearward end is stretched out sleeve 4, further, seals by the plastic seal screens between the rearward end of blood sampling tube 1 and the sleeve 4, between blood sampling tube 1 and sleeve 4, be provided with slide locating mechanism, between the front end of blood sampling tin 1 and sleeve 4, be provided with back-moving spring 7.
Described detent mechanism comprises L shaped push jack 2, at least two draw-in grooves 3 that leave the gap and be used with push jack 2 that are symmetricly set on blood sampling tube 1 both sides, with the rectangular triangle of draw-in groove 3 contacted push jack 2 leading sections, when not using, push jack 2 places in the draw-in groove 3 topmost.
Concrete, the position between the draw-in groove 3 can be regulated according to practical situation.
Described sleeve 4 front ends are provided with cover 6.
Blood sampling of the present utility model tube 1 terminal seal cover 8 modes that adopt that is to say that this end is movable to take off, and can conveniently the blood in the blood sampling tube 1 be taken out like this.
In force, to twist into two parts the plastic seal between blood sampling tube 1 and the sleeve 4 earlier, whole like this blood taking needle just is in state to be used, after pressing blood sampling tube 1, the push jack 2 of button left and right sides will move downward, and extrusion spring makes spring produce elastic force simultaneously, under the cooperation of spring and draw-in groove 3, puncture needle 5 just stretches out sleeve 4 and finishes puncture, after blood sampling finished, the push jack 2 of blood sampling tube 1 was blocked by the draw-in groove 3 of downside, made blood sampling tube 1 can't get back to original state, like this, blood taking needle can't be used for the second time.
