Specific embodiment
Below in conjunction with attached drawing, the present invention is described in detail.
Embodiment：A kind of needle holder suitable for blood taking needle, structure as shown in Figs 1-4, including：
Needle mount body 2 with handle 5.The inside of needle mount body 2 has the blood sampling channel 2-2 of Y-direction, X-direction
Storage blood channel 2-1 and Z-direction control-rod 4；
The both ends of control-rod 4 protrude from the needle mount body 2；
The side of the needle mount body 2 is provided with the negative pressure sac 3 connected with storage blood channel 2-1；
2 bottom of needle mount body is fixedly connected with elastomeric element 10, and the elastomeric element 10 is through on the control-rod 4
Through-hole 4-3；
Wherein, 4 top of control-rod is provided with the three-dimensional runner for syringe needle, hose to be connected with storage blood channel 2-1
4-1；
4 lower part of control-rod is provided with the reversible passage 4-2 for syringe needle to be connected with hose.
Preferably, there is anti-skid chequer 5-1 on the handle 5.
According to different needs, the elastomeric element 10 is the adhesive tape or spring of rubber material.
Meanwhile the three-dimensional runner 4-1 is T-shaped or Y types.
Refering to what is shown in Fig. 5, under use state, the front end of needle mount body 2 is connected with syringe needle 1, and rear end is connected with hose 6,
Form the structure of the syringe needle 1 of airtight connection, needle mount body 2, hose 6, middle base 7, self-styled rubber plug 8 and negative tube 9 successively.In
Between seat 7 and self-styled rubber plug 8 be plug connection so that the present apparatus can pull out middle base 7 after the completion of blood sampling from self-styled rubber plug 8
Go out, reservation to be facilitated to acquire the negative tube 9 of blood sample.
The application method of the present invention is as follows：
Before blood sampling, in the case where not applying external force, control-rod 4 shows state shown in Fig. 2, i.e., by elastomeric element 10
Position-limiting action, control-rod 4 can not move down.At this point, the reversible passage 4-2 on control-rod 4 leads to the blood sampling in needle mount body 2
Road 2-2 is connected, but the channel 2-2 that takes a blood sample is not connected with storage blood channel 2-1.
During blood sampling, medical staff's left hand presses patient's arm, and right hand thumb is located at 5 upside of handle, and forefinger is located at handle 5
Downside, thumb, which far saves lower part and far saves lateral engagement grips said handle 5 with forefinger, to be punctured, then syringe needle 1 enters patient body,
Under negative pressure and blood pressure effect, blood automatic stream negative tube 9 realizes blood sampling.
After blood in negative tube 9 reaches design capacity, medical staff's left hand presses puncture orifice, the food of the right hand by cotton balls
Side is saved in finger and is located at 5 downside of handle, thumb far section is located at the upside of handle 5 close to the part of middle section, and thumb far section is remote
Part from middle section is located at 2 top (part between control-rod 4 and syringe needle 1) of needle mount body so that thumb far saves
It retracts close to the part of middle section with saving lateral engagement grips said handle 5 in forefinger, then syringe needle 1 is just extracted from patient's body.
As shown in figure 4, while pulling out needle, thumb far section moves backward realization pressing control-rod 4, then control-rod 4 will
It moves down so that three-dimensional runner 4-1 will store up blood channel 2-1 and be connected with blood sampling channel 2-2 so that negative pressure sac 3 and three-dimensional runner 4-1
Connection, then the blood in the blood and hose 6 in syringe needle 1 can be flowed to negative pressure sac 3 so that and the blood in syringe needle 1 will not drip, and then
Avoid cross-infection.
The principle of the present invention and innovation are：
After the completion of blood sampling and when syringe needle does not extract body, under blood pressure effect, although will not be flowed full of blood in syringe needle
Go out.And once syringe needle extracts body, the blood in syringe needle can drip under the effect of gravity.
Blood of leaving in syringe needle 1 can be attracted using the negative pressure sac 3 additionally set, be avoided and leave drop of blood by the present invention
It falls.
Tool is there are two channel on control-rod 4 so that control-rod 4 not under the action of by external force, can normally by syringe needle 1 with
Negative tube 9 is connected.And syringe needle 1, hose 6 and negative pressure sac 3 are connected in the case where being acted on by finger pressure for control-rod 4, then syringe needle 1
With leaving blood and can enter in negative pressure sac 3 in hose 6.After finger unclamps, negative pressure sac 3 shows air-tight state again, then
Internal blood would not flow out.
Negative pressure sac 3 can suck the blood in hose 6 during sucking blood, but will not be by the blood sample in negative tube 9
This sucking.Even if the reason is that, middle base 7 not with one end that hose 6 connects after negative tube 9 acquires full blood sample because negative
Pressure pipe 9 still has segment space, so can not be immersed under blood sample, and then can not suck blood sample (in short
It, under the premise of vacuum degree in negative tube 9 is certain, blood sample can not fully take up whole spaces of negative tube 9).Into
And finally ensure that the actual capacity of blood sample is consistent with design capacity.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications of these embodiments will be apparent for those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to consistent with principles disclosed herein and feature
Most wide range.
