Abstract
A kind of visual double end blood taking needle, it is on the basis of general double end blood taking needle, changes the raw material of needle stand (8) into transparent plastic, and is feasible in order to make, and needle stand is divided into two, and sticks to one.In needle stand, set up needle tubing space (9), blood back obstructing tube (5), blood back hole (3) and blood back are observed storehouse (4).During blood sampling, blood flow flows into blood back by venipuncture needle tubing (1), needle tubing space (9), blood back obstructing tube (5), blood back hole (3) and observes storehouse (4) under the effect of blood pressure, can clear observation blood back, judge the puncture success or not, and can blindly not prick.Blood back after the embodiment blood sampling of Fig. 1 is because the effect of blood back obstructing tube can not be removed the sign after can using, strong prevention repeated use.
Description
Affiliated technical field
This utility model relates to the category of medical apparatus and instruments, particularly a kind of disposable visual double end blood taking needle.
Background technology
At present, during blood test, adopt blood taking needle to be equipped with vacuum test tube, substitute the blood collection needle injecting tube and carry out blood test, generally adopt at national various big hospital.But there are many disadvantages with the matching used double end blood taking needle of vacuum test tube, bring many worries for medical personnel and patient.The double end blood taking needle needle stand of current trend is opaque, and its color determines that by the needle point specification end is provided with venipuncture needle, and an end is provided with the pipe close puncture needle, is furnished with seal rubber sleeve.During use, earlier venipuncture is needled into vein, again pipe close puncture needle end is thrust vacuum test tube, carry out blood specimen collection.But because the double end needle stand is opaque, do not have the slit between two pins, the pipe close puncture needle is sealed by gum cover again, so can't observe blood back, belongs to blind bundle.The unsuccessful accident of taking a blood sample happens occasionally, and has only in the time of can not taking a blood sample behind the puncture blood collecting pipe and could find, has not only wasted blood taking tube (loss of vacuum) but also has increased patient's misery (must have an acupuncture treatment again).As seen popular double end vacuum blood taking needle is demanded urgently improving.
Summary of the invention
Can not observe the deficiency of blood back in order to overcome the double end blood taking needle, this utility model provides a kind of visual double end blood taking needle, this blood taking needle is when blood sampling, in case can observe blood back immediately as long as venipuncture needle punctures successfully, loseing blood back then is that the puncture vein is unsuccessful.
The technical scheme that its technical problem that solves this utility model adopts is: change double end blood taking needle needle stand into transparent plastic and make, and in transparent needle stand, set up the needle tubing space, blood back obstructing tube, blood back hole and blood back are observed the storehouse, during blood sampling, because human blood-pressure effect, blood can flow into the blood back obstructing tube from the slit between venipuncture needle tubing and pipe close puncture needle tubing, goes into blood back by the blood back orifice flow of blood back obstructing tube again and observes the storehouse, increases visual degree.After seeing blood back, prove the venipuncture success, the puncture blood collecting pipe is taken a blood sample again.Visual double end blood taking needle after the use remains in a little blood back that blood back is observed the storehouse, because the iris action of blood back obstructing tube, can not sucking-off, also can't clean, be the used obvious sign of disposable using apparatus, can effectively prevent the repeated use of blood taking needle.
The beneficial effects of the utility model are can observe blood back when venous blood collection, avoid blind bundle, improve the blood sampling success rate; After the use, blood back can not be removed, and can effectively prevent repeated use.Structure is also uncomplicated, and cost of manufacture increases little, and is convenient to use, very easily promotes.
Description of drawings
Below in conjunction with accompanying drawing, this utility model is further specified.
Fig. 1 is a principle cutaway view of the present utility model.
Fig. 2 is the principle cutaway view of second embodiment of the present utility model.
Among the figure: 1, vein blood taking needle needle tubing, 2, seal gasket, 3, the blood back hole, 4, blood back observes the storehouse, 5, the blood back obstructing tube, 6, the pipe close puncture needle tubing, 7, pipe close puncture needle gum cover, 8, double end blood taking needle needle stand, 9, the needle tubing space.
The specific embodiment
Among Fig. 1: change the raw material of double end blood taking needle needle stand (8) into transparent plastic, needle stand is divided into two, stick together then, blood back is set in needle stand (8) observes storehouse (4), a blood back obstructing tube (5), and establish two above blood back holes (3) in the lower end of blood back obstructing tube (5), the lower end of blood back obstructing tube (5) is provided with a seal gasket (2), the tail end of venipuncture needle needle tubing (1) is exposed length a bit,, stay a needle tubing space (9) near the tail end of pipe close puncture needle tubing (6).Behind the visual double end blood taking needle puncture vein, blood flow is under the effect of blood pressure,---needle tubing space (9)---route that blood back obstructing tube (5)---blood back hole (3)---blood back is observed storehouse (4) flows into blood back observation storehouse (4) along venipuncture needle needle tubing (1), play the effect that to observe blood back, can directly see the blood back situation this moment, judge that accurately whether acupuncture treatment, take a blood sample smoothly.After seeing blood back, the pipe close puncture needle tubing (6) of visual double end blood taking needle is thrust vacuum test tube, at this moment pipe close puncture needle gum cover (7) is passed, channel of blood flow and vacuum test tube UNICOM, and the blood automatic ration flows into vacuum test tube, finishes blood specimen collection smoothly.
Blood is observed the blood back in the storehouse, can not flow out fully under the effect of blood back obstructing tube, inhales also and can not inhale, and also can't clean, and with the naked eye just can discern and use.Can play and prevent reusable effect.
Among the another kind of embodiment shown in Figure 2, saved blood back obstructing tube (5), blood back hole (3), seal gasket (2), but still can observe the clear observation blood back in storehouse (4) from the blood back that keeps.It is simpler than first embodiment, saves cost, therefore also very easily promotes.
Claims (3)
1, a kind of visual double end blood taking needle, be linked in sequence and make by vein blood taking needle needle tubing (1), double end blood taking needle needle stand (8), pipe close puncture needle tubing (6), pipe close puncture needle gum cover (7), it is characterized in that: double end blood taking needle needle stand (8) is made by transparent plastic, set up needle tubing space (9), blood back obstructing tube (5), blood back hole (3) and blood back in the needle stand and observe storehouse (4), during blood sampling, can clear observation blood back.
2, visual double end blood taking needle according to claim 1, it is characterized in that: double end blood taking needle needle stand (8) is to be made by transparent plastic.
3, visual double end blood taking needle according to claim 1 is characterized in that: set up needle tubing space (9), blood back obstructing tube (5), blood back hole (3) and blood back and observe storehouse (4) in transparent needle stand.
