It is disclosed on 2 13rd, 2018 Chinese patent literature CN206995273U and describes a kind of clinical laboratory and adopted with capillary
Blood needle, including syringe needle, syringe needle upper end are equipped with syringe needle tube, and syringe needle tube interior lower end is equipped with capillary, which is equipped with storage
Haemocoele, the syringe needle tube upper surface are equipped with extension bar, and the junction outer surface of the syringe needle tube and extension bar is provided with stress slot, described
Stress slot is to syringe needle tube internal stretch and end is equipped with failure crack, and extension bar top is equipped with lever, and lever top is equipped with handle
Frame.The technical solution is sucked blood using the capillary in syringe needle tube and passes through storage haemocoele storage blood, and blood sampling time is long, low efficiency.
Utility model content
Problem to be solved in the utility model is to provide a kind of Novel blood taking needle, to improve capillary blood taking needle in the prior art
Structure is complicated for blood sampling, and cost of manufacture is high, elapsed time long problem when blood sampling.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of Novel blood taking needle is designed, including needle tubing and the grip part that needle tubing tail end is arranged in, is arranged on the grip part
The through-hole of the lumen of flexible blood storing capsule and the connection elastic blood storing capsule and the needle tubing in the grip part.
Preferably, the through-hole includes first through hole, and the first through hole is formed with perforation in the side of the needle tubing.
Preferably, the through-hole includes the second through-hole, and second through-hole connects with the tail end of the needle tubing so that described
Second through-hole is communicated with the lumen of the needle tubing.
Preferably, the grip part is the cylinder coaxial with the needle tubing, and the cylinder is equipped with groove, the elasticity storage
Haematodocha be arranged in the groove, and the elasticity blood storing capsule in the raw when, outer surface is located at the side of the cylinder
In enclosed region.
Compared with prior art, the advantageous effects of the utility model are:
1. structure is simple；Low manufacture cost；
2. being arranged elastic blood storing capsule on grip part, the effect by compression elasticity blood storing capsule can be realized when holding needle tubing
The air in elastic blood storing capsule can be discharged in fruit in this way, unclamp by after compression elasticity blood storing capsule, elastic blood storing capsule is inhaled when restoring to the original state
Blood can be accelerated to take blood speed.

Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses
It is described in detail the utility model, does not limit the scope of the utility model in any way.
Embodiment 1: a kind of Novel blood taking needle, referring to Fig. 1-3, including needle tubing 1 and the grip part 2 that 1 tail end of needle tubing is arranged in,
Flexible blood storing capsule 3 is set on grip part 2 and is connected to the through-hole of elastic blood storing capsule 3 and the lumen of the needle tubing 1 in grip part 2.
In the present embodiment, grip part 2 be it is flat-shaped, through-hole includes first through hole 22, side shape of the first through hole 22 in needle tubing 1
At there is perforation.The transparent soft polyvinyl chloride plastic of material selection medical poisonless of elastic blood storing capsule 3；Elastic blood storing capsule 3 is provided only on
The side of grip part 2, such index finger and middle finger can be with another side contacts of grip part 2, first is that having gripping sense, second is that being in one's hands
The elastic blood storing capsule for avoiding squeezing the other side can be easier when holding, three are easy for placing Chu Xuezhen.
For the Novel blood taking needle when unused, elastic blood storing capsule has no bacteria live environment.
When using strict standard, in manufacturing process, the gas in elastic blood storing capsule 3 should be discharged in an aseptic environment, and
So that it is sucked filtrated air, and is packed into hard box and causes to suck air in it to prevent from squeezing elastic blood storing capsule 3.In this way, elasticity storage
Gas in haematodocha 3 is in stable state, has the effect of similar flask.
In use, index finger and middle finger hold the back side of grip part 2, thumb is by compression elasticity blood storing capsule 3 to be discharged in it
Gas after taking needle tubing insertion at blood, slowly unclamps elastic blood storing capsule 3, and the elastic blood storing capsule 3 that such blood is just resumed original sample is logical
Cross needle tubing, through-hole sucks in elastic blood storing capsule.When taking needle, thumb is moved into the periphery of elastic blood storing capsule 3, transfers to blood taking needle,
It is thus avoided that and squeezes out the blood in elastic blood storing capsule 3, then properly place Chu Xuezhen.
When needing using blood in storage blood needle, squeeze elastic blood storing capsule 3, the blood in elastic blood storing capsule 3 successively from
Through-hole, needle tubing discharge.
Embodiment 2: a kind of Novel blood taking needle, as the another embodiment of the utility model, referring to Fig. 1-3, this reality
Apply example difference from example 1 is that, through-hole include the second through-hole 21, the second through-hole 21 connect with the tail end of needle tubing 1 with
Communicate the second through-hole 21 with the lumen of needle tubing 1.The through-hole formed in this way, manufacture craft are simple.In the present embodiment
In, first through hole 22 may exist, and can also be not present.
Embodiment 4: a kind of Novel blood taking needle, as the another embodiment of the utility model, referring to fig. 4-6, in Fig. 4
In, it is not drawn into elastic blood storing capsule, the present embodiment is a difference in that with embodiment 1: grip part 2 also can be set into same with needle tubing
The cylinder of axis is more closely similar to syringe in this way, and the gripping range of hand-held part is bigger, and groove can be set on grip part 2
23 to accommodate elastic blood storing capsule 3, and make elastic blood storing capsule in the raw when, outer surface is located at the side area Suo Wei of cylinder
In domain.In the present embodiment, correspond to Fig. 4 when, elastic blood storing capsule 3 by groove 23 and the damaged surface of grip part 2 boundary line
The shape being mixed to form through sideline, the storage for blood taking needle of being more convenient in this way, moreover, when holding blood taking needle, can with thumb and
Middle finger is held, and by the way of index finger pressing, such grip effect is more preferable.
The utility model is described in detail above in conjunction with drawings and examples, still, the skill of technical field
Art personnel, can also be to each specific ginseng in above-described embodiment it is understood that without departing from the purpose of the present invention
Number changes, and forms multiple specific embodiments, is the common variation range of the utility model, is no longer described in detail one by one herein.
