Chemically examine cost；3, more parts of blood samples can be acquired simultaneously, improve venous blood sample collection efficiency；4, new without puncturing repeatedly
The rubber seal plug of the vacuum tube changed ensure that the aseptic collection of sample, it is ensured that the accuracy of result of laboratory test；5, on wing handle
Fixing belt, immobilized patients arm and blood taking needle can be played the role of, avoid blood taking needle in blood collection procedure from being touched, cause vein
The case where being punctured；6, blood taking needle can bounce back in sheath after taking a blood sample, and will not cause to hand over because blood collection needles are exposed
Fork infection, securely and reliably.
Detailed description of the invention:
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the positive structure schematic of the present embodiment.
In figure: heparin tube 1, blood taking needle 2, current divider 3, switch 4, connector 5, vacuum tube 6, isocon 7, wing handle 8,
Fixing belt 9, sheath 10, casing 10-1, squeezing handle 10-2, sliding slot 10-3, limiting slot 10-4.
Specific embodiment:
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1:
A kind of venous blood-taking apparatus as shown in Figure 1 comprising heparin tube 1, blood taking needle 2, current divider 3, connector 5 and
Vacuum tube 6；
One end of heparin tube 1 is connected to blood taking needle 2, and the other end of heparin tube 1 is connected to a port of current divider 3, point
It flows and is equipped with switch 4 on remaining port of device 3, each switch 4 is connect with a connector 5, and connector 5 and vacuum tube 6 connect
It is logical；It further includes isocon 7, and switch 4 is connected to connector 5 by isocon 7.Multiple vacuum tubes 6 can be once accessed to carry out
Blood sampling, is greatly saved blood sampling time, improves blood sampling efficiency, while reducing pain when patient's blood sampling.
It further includes handle, and handle is set on blood taking needle 2, and handle is wing handle 8, is connected on wing handle 8 solid
Determine band 9, fixing belt 9 is equipped with attachment device, and attachment device is thread gluing or snap-fastener, can play immobilized patients arm and blood taking needle 2
Effect, entire blood collection procedure can avoid the case where being touched, vein is caused to be punctured of blood taking needle 2.
It further includes sheath 10, and sheath 10 includes the squeezing handle 10-2, casing 10-1 and squeezing handle 10- of casing 10-1 and hard
2 are sheathed on heparin tube 1, and one end of squeezing handle 10-2 is fixedly connected with casing 10-1 far from one end of wing handle 8；It is covering
The sliding slot 10-3 to match with the fin of wing handle 8 is offered on pipe 10-1, and limiting slot 10-4 is offered on squeezing handle 10-2,
Sliding slot 10-3 is connected to limiting slot 10-4, and the width of sliding slot 10-3 is gradually reduced by the direction of blood taking needle 2 to wing handle 8,
The width of sliding slot 10-3 and the sliding slot 10-3 of the junction limiting slot 10-4 are less than the width of limiting slot 10-4, the height of limiting slot 10-4
Degree is greater than the height of the fin of wing handle 8；After blood sampling, it can be pulled on the other hand by the squeezing handle 10-2 of a hand grip hard
Heparin tube 1 makes the fin of wing handle 8 have sliding slot 10-3 to slide into limiting slot 10-4, and then makes blood taking needle 2 that can bounce back to shield
In set 10, since squeezing handle 10-2 uses hard material, limiting slot 10-4 will not be loose because of external force, the wing of wing handle 8
Piece would not also skid off limiting slot 10-4, thus more safe and reliable.
Casing 10-1 is designed as inclined-plane or curved surface far from the one end of the squeezing handle 10-2, and the minimum point on inclined-plane is sliding slot
The fin of the import department of 10-3, wing of being more convenient for handle 8 enters in sliding slot 10-3.The lower end oral area and limiting slot of sliding slot 10-3
The oral area of 10-4 deviates, shift ratio 1:3；It is also contemplated that the fin of wing handle 8 is living in the middle position of limiting slot 10-4
Dynamic probability is larger, and the offset setting of the oral area of the lower end oral area of sliding slot 10-3 and limiting slot 10-4 can further be limited blood sampling
Needle 2 is exited from sheath 10.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
