Method is moved, and puncture needle can not also stretch out protection suite, it is ensured that safety, is so also avoided that the secondary of blood taking needle is used.
The unidirectional slip of single can only be carried out between the presence of non-return device, therefore protective case and blood taking needle body simultaneously due to having
It is locked.If any maloperation, protective case and blood taking needle body are carried out before blood sampling locked, then, safe blood-taking needle is also by nothing
Method is used.Existing safe blood-taking needle can not prevent above-mentioned maloperation, easily cause the waste of medical resource.
In addition, the negative pressure amount for the vacuum blood collection tube that existing safe blood-taking needle is connected is set according to blood sampling volume.
In Clinical practice, due to need to first prick Esmarch's bandage on human body, and rise in the Esmarch's bandage limbs lower end intravascular pressure tightened,
Blood is flowed into negative pressure state vacuum blood collection tube after safe blood-taking needle intervention vein, and preset negative pressure exhausts blood sampling and terminated, now, blood
Pipe internal pressure is identical with vacuum blood collection tube internal pressure.But take a blood sample after terminating, it is necessary to take Esmarch's bandage, intravascular pressure can be reduced rapidly, weight
Normal arterial pressure newly is returned to, now vacuum blood collection tube is also connected with blood vessel, and vacuum blood collection tube internal pressure is then more than intravascular pressure, it is possible to
The blood taken is caused to return intravascular and occur risk of infection.
In view of drawbacks described above, it is new that the utility model creator obtains this practicality finally by prolonged research and practice
Type.

In seat 31 so that forward block 34 closes guide rail through hole 35.So, the blood remained at the needle point of puncture needle 2 can not flow out protection
The outside of external member 4.
Needle holder 6 is internally formed the second cavity, and the second cavity is used to accommodate vacuum blood collection tube.The outer wall of needle holder 6 is in cylinder
Type.The internal diameter of the port of needle holder 6 is more than the external diameter of vacuum blood collection tube.Needle holder 6 is directly socketed on vacuum blood collection tube.
Tailpin 7 is arranged at the inside of the cavity of needle holder 6 second, for inserting and connecting vacuum blood collection tube.Outside tailpin 7 by
Quality of rubber materials is wrapped up.Connection flexible pipe 5 is connected by tailpin 7 with vacuum blood collection tube.The inside of tailpin 7 is provided with suck blood filter paper or cotton of sucking blood
Or medical non-woven fabrics or glass fibre.When tailpin 7 is extracted from the vacuum blood collection tube equipped with blood, suck blood filter paper or cotton of sucking blood
Or medical non-woven fabrics or glass fibre can pin the blood in tailpin 7, blood is not flowed out tailpin 7.
The utility model embodiment one is before blood sampling, and the needle body of puncture needle 2 is located at outside protection suite 4, puncture needle 2 it is logical
Cross puncture needle shield 3 and extraneous physical isolation.Needle shield 3 will be first punctured during blood sampling to remove, and puncture needle 2 is exposed.Medical worker
It is hand-held to hold pin handle 14, the second groove 21 is then pressed close into human body, and adjust the angle of the piercing of puncture needle 2.When puncture needle 2 is correctly pierced
Enter after blood vessel, vacuum blood collection tube is inserted in needle holder 6, while making tailpin 7 be pierced into inside vacuum blood collection tube.So, puncture
Pin 2, the first cavity, connection flexible pipe 5, tailpin 7 and vacuum blood collection tube formation blood access.Due to being negative pressure in vacuum blood collection tube,
Therefore, the blood in human body flows into vacuum after passing sequentially through puncture needle 2, the first cavity, check valve 50, connection flexible pipe 5 and tailpin 7
Heparin tube.Check valve 50 prevents the blood in vacuum blood collection tube from flowing back again into the human body, pollutes.When check valve 50 first
Before unlatching, latch 52 is in the lock state, the relative motion of limitation blood taking needle body 1 and protection suite 4, to prevent before blood sampling
The generation of maloperation.After check valve 50 is opened for the first time, you can ensure that blood collection procedure has begun to, then allow blood taking needle body
Slip between 1 and protection suite 4.
After blood sampling volume reaches requirement, vacuum blood collection tube is extracted into needle holder 6, then pulled out by puncture needle 2 from human body
Go out, complete blood collection procedure.After blood sampling is completed, medical worker places puncture needle 2 straight up, makes what is remained on puncture needle 2
Blood holds downwards the flowing of the direction of blood groove 18, and then medical worker's both hands hold protection suite handle 16 and hold pin handle 14 respectively,
Pin handle 14 is held in pulling, and opposite direction promotes protection suite handle 16 so that the first buckle 23 is caught in the first groove 10, the second card
Button 24 is caught in the second groove 11.As shown in figure 11, it is that blood taking needle body is used with protection suite in the utility model embodiment one
Attachment structure schematic diagram afterwards.First buckle 23 is caught in the first groove 10, and the second buckle 24 is caught in after the second groove 11, protection
External member 4 and blood taking needle body 1 are locked mutually, it is impossible to relatively moved again.Puncture needle 2 departs from guide rail through hole 35 and is received to
Inside protection suite 4.
After puncture needle 2 departs from guide rail through hole 35, the tip portion of puncture needle 2 is stayed in outside appearance blood groove 18 and protection suite 4
In the cavity that shell is surrounded.After puncture needle 2 departs from guide rail through hole 35, elastomeric element 33 promotes connectivity kit 32 along guide rail 30
It is interior to slide so that forward block 34 moves and closes guide rail through hole 35.So, the blood remained at the needle point of puncture needle 2 can not flow
Go out the outside of protection suite 4.The blood remained on puncture needle 2 can be flowed into appearance blood groove 18 by push-and-pull, and by appearance blood groove 18
Suck blood cotton or filter paper of sucking blood is absorbed.
Embodiment two
Difference between the utility model embodiment two and embodiment one is：As shown in figure 12, it is that the utility model is real
Apply the overlooking the structure diagram of needle holder in example two；As shown in figure 13, it is the main view of needle holder in the utility model embodiment two
