Description
Technical field
The utility model relates to medical experiment equipment technical field, especially a kind of disposable micro blood-taking tube is used
It is measured in human body physiology experiment teing content of hemoglobin.
Background technique
In Physiology Experiment, the measurement of content of hemoglobin is often carried out, it is disposable micro using 20 μ l when measurement
Heparin tube, structure is as shown in Fig. 2, be arranged band plug hollow eraser ball 2, column shape heparin tube 11 in 11 rear end of column shape heparin tube
It is equipped with scale 1-1.When blood sampling, routine disinfection finger tip punctures finger with disposable lancet, flows out to drop of blood, with disposable
Using the nib contacts drop of blood of micro blood-taking tube 11, the other end has hollow eraser ball 2, squeezes rubber ball 2 and blood is drawn in pipe
At scale.
This heparin tube simple structure, it is very economical, but use is unsatisfactory, and there are many deficiencies: since drop of blood is difficult to
Completely enclosed heparin tube tip is easy to sucking air when sucking blood, cause blood sampling volume inaccurate；Process of sucking blood is slightly slow, and drop of blood holds very much
Easily wandering, wound not bleeding again leads to quantitative blood sampling failure；Rubber ball undue force is squeezed, and is easy to blood sucking rubber
In ball, blood sampling is caused to fail.
Utility model content
The utility model in view of the deficiencies of the prior art, proposes a kind of disposable micro blood-taking tube, and it is accurate to be both conducive to
Quantitative blood sampling, but production is simple and convenient to operate, is economical and practical.
In order to realize above-mentioned purpose of utility model, the utility model is the following technical schemes are provided: a kind of disposable micro-
Heparin tube is measured, including heparin tube, band plug hollow eraser ball and rubber dish are buckled, the band plug hollow eraser ball and the heparin tube
Back-end sealing connection, the rubber cap that the rubber dish is buckled as bottom of which has holes are sealedly connected on the front end of the heparin tube.
Further, the heparin tube is tubaeform, and it is larger that one end bore being connected to is buckled with the rubber dish.
Further, the rubber dish buckles bottom and is equipped with the thin eye net of filament for covering the blood sampling pipe port.
Further, movable lightweight bead is equipped in the heparin tube, the outer diameter of the lightweight bead is greater than the blood sampling
Pipe rear port internal diameter, less than the internal diameter of the heparin tube front port.
Further, the heparin tube rear portion is equipped with graduation mark, and the outer diameter of the lightweight bead is equal to the heparin tube and exists
Internal diameter at graduation mark.
Further, the net diameter that the filament dredges eye net is less than the outer diameter of the lightweight bead.
Compared with prior art, the utility model has the advantage that buckles in heparin tube front end setting rubber dish, detains cover blood
Drop prevents drop of blood diffusing, closes end of sucking blood, and conducive to sucking blood, prevents sucking air；And setting bead can prevent from squeezing in heparin tube
Press rubber ball is improper to absorb blood in rubber ball；Structure is simple, and operation is easy, securely and reliably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the disposable micro blood-taking tube of the utility model；
Fig. 2 is common disposable micro blood-taking tube structure chart；
Diagram label:
1 tubaeform heparin tube, 1-1 scale, 1-2 bead, 11 column shape heparin tubes, 2 band plug hollow eraser balls, 3 rubber dish
Button, 3-1 filament dredge eye net.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to the protection scope of the utility model.
As shown in Figure 1, a kind of disposable micro blood-taking tube, including heparin tube 1, band plug hollow eraser ball 2 and rubber
Dish buckles 3, and the band plug hollow eraser ball 2 is connect with the back-end sealing of the heparin tube 1, and the rubber dish buckles 3 as bottom of which has holes
Rubber cap, be sealedly connected on the front end of the heparin tube 1.
In the front end of heparin tube 1, the rubber dish of setting sealing socket buckles 3, directly be located in and takes by the cover that rubber dish buckles 3
At blood, end of sucking blood is closed, prevents air from entering, and prevent drop of blood diffusing, conducive to sucking blood to heparin tube 1.
It is larger that heparin tube 1 using tubaeform, with the rubber dish buckles one end bore that 3 are connected to, and rubber dish is undoubtedly made to buckle 3
Cover be easier to cover and entirely take at blood, and blood is easily accessible heparin tube.
Filament is equipped in the bottom that rubber dish buckles 3 and dredges eye net 3-1, covers the front port of heparin tube 1, the blood necessarily acquired
It needs to dredge eye net 3-1 by the filament；Due to taking blood, especially finger tip to take blood, usually first squeezes out one and bleed, when rubber dish is buckled
3 cover entirely when taking at blood, which dredges eye net 3-1 and first touch drop of blood surface, enters in heparin tube 1 convenient for drainage.
The twine that filament dredges eye net 3-1 can be very thin, smooth, can be made of proof nylon, metal etc..
Lightweight bead 1-2 is set in heparin tube 1, and outer diameter is greater than the 1 rear port internal diameter of heparin tube, adopts less than described
The internal diameter of 1 front port of blood vessel.When acquiring blood, lightweight bead 1-2 be cannot be introduced into band plug hollow eraser ball 2, to be also prevented from
Excessive compression band plug hollow eraser ball 2 is sucked into blood in band plug hollow eraser ball 2.
Since heparin tube front end setting filament dredges eye net 3-1, the work for stopping lightweight bead 1-2 forward end to drop out is also functioned to
With；Therefore this lightweight bead 1-2 can only be dredged in filament moves between 1 rear port of eye net 3-1 and heparin tube.
Filament, which dredges eye net 3-1, can be used the big eye net that mesh is less than the small ball's diameter.
1 rear portion of heparin tube is equipped with graduation mark 1-1, and the outer diameter of the lightweight bead 1-2 is equal to the heparin tube 1 in graduation mark
Internal diameter at 1-1 defines that lightweight bead 1-2 can be dredged in filament and moves between eye net 3-1 and scale 1-1, but falls outside not outlet pipe.
The use step of the utility model: (1) routine disinfection finger tip punctures finger with disposable lancet, squeezes to blood
Drip goes out.(2) rubber ball 2 is squeezed.(3) rubber dish 3 are buckled to be buckled on drop of blood.(4) rubber ball is discharged, it is small in blood suction line
Ball 1-2 is drawn at scale 1-1.(5) blood is squeezed into the chromocytometer being ready for.(6) enter content of hemoglobin to measure
Experiment.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
