It please refers to Fig.1 to Fig. 5, blood taking needle provided in an embodiment of the present invention, including single-blade punctures needle shield and needle tubing
30, blood sampling conduit 40, heparin tube puncture needle 50.
Wherein, it includes sheath 10, needle tubing seat 20 and needle handle 60 that the single-blade, which punctures needle shield, and needle handle 60 is arranged in needle
On tube socket 20, the needle tubing 30 is mounted on the needle tubing seat 20, and the needle tubing seat 20 and the needle tubing 30 are set to the sheath
In 10 cavity, and the needle tubing seat 20 and the needle tubing 30 can be slided and be rotated in the cavity of the sheath.
In sector, product specifically is affectedly bashful to facilitate for the needle handle 60, convenient for blood sampling operation.
Blood sampling conduit 40 is connect with heparin tube puncture needle 50, and the blood sampling conduit 40 is connected to the needle tubing 30.Specifically,
Needle tubing seat 20 is equipped with through-hole backwards to one end of needle tubing 30, for connecting blood sampling conduit 60, since blood sampling conduit 40 and heparin tube are worn
The structure of pricker 50 is universal architecture, and therefore, it will not be described here.In addition it should be pointed out that blood sampling conduit 40 can root
It is omitted according to actual conditions, i.e., heparin tube puncture needle 50 directly connect with needle tubing seat 20 to blood was collected operation can equally reach
To the technique effect of the present invention, therefore, whether the present invention includes that blood sampling conduit 40 is not limited to blood taking needle.
The sheath 10 is equipped with the first open slot 101 and the second open slot 102, first open slot 101 and described the
Two open slots 102 communicate.
The first position-limit mechanism 11 is equipped in first open slot 101, the blood taking needle is before use, first limit
The needle handle 60 is stuck in first open slot 101 by mechanism 11, so that the needle tubing seat 20 and the needle tubing 30 are fixed on
In the cavity of the sheath 10.It should be pointed out that 10 length of sheath should be suitable, guarantee fully wrapped around firmly needle tubing 30,
Needle tubing 30 is avoided to expose.
Wherein, first position-limit mechanism 11 is specially boss structure of the protrusion direction towards the needle tubing 30.In order to protect
It is 60 limit effect of needle handle to demonstrate,prove the first position-limit mechanism 11, two boss structures can be arranged, two boss structures are separately positioned on
The both ends of first open slot 101.
The second position-limit mechanism 12 is equipped in second open slot 102, the needle handle 60 can be in second open slot 102
Interior sliding, meanwhile, the second open slot 102 can limit the sliding of needle handle 60, needle tubing seat 20, needle tubing 30, make it by specified side
To, distance sliding.
Wherein, second position-limit mechanism 12 is specially projecting thorn structure of the protrusion direction towards the needle tubing seat 20.
The blood taking needle pushes after the completion of blood sampling, by the needle handle 60 towards the direction of second position-limit mechanism 12, directly
The needle handle 60 is blocked to second position-limit mechanism 12, so that the needle tubing seat 20 and the needle tubing 30 are fixed on the shield
In the cavity of set 10.
In the present embodiment, in order to promote using effect, avoid sliding in the hand in sheath 10, the outside of the sheath 10 is set
There is anti-skid chequer 70.Some small columns can also be arranged to increase the frictional force that skin is contacted with product, into one above in anti-skid chequer 70
Step prevents rubber sleeve.
The sheath 10, the needle tubing seat 20, the needle handle 60 can be all made of elastic component.Such as elasticity may be used
Plastic part.
According to above-mentioned blood taking needle, before use, needle handle 60 is stuck in the first open slot 101 by the first position-limit mechanism 11
It is interior, so that needle tubing seat 20 and needle tubing 30 are fixed in the cavity of sheath 10, avoid needle tubing 30 is exposed from causing product failure；?
When needing blood sampling, a hand pinches sheath 10 (can specifically pinch anti-skid chequer 70), and another hand pinches needle handle 60, by needle handle 60
It is broken toward 102 direction of the second open slot, was broken the first position-limit mechanism 11, needle handle 60 is made to fall into second from the first open slot 101
In open slot 102, needle handle 60 is then pinched, and bottom is shifted onto along the second open slot 102, so that needle tubing 30 is exposed, then by needle tubing
30 needle tip is pierced into vein blood vessel and draws blood；It waits after drawing blood, pinning sheath 10 with hand (can specifically pin anti-skidding
Line 70) and pinch needle handle 60, needle tubing 30 is slowly extracted from vein blood vessel along the second open slot 102, and continue to make needle handle
60 shrink back, until needle handle 60 slips over the second position-limit mechanism 12, are blocked needle handle 60 by the second position-limit mechanism 12 so that needle tubing
Seat 20 and needle tubing 30 be fixed in sheath 10, so as to prevent needle tubing 30 is exposed, avoid needle tubing miss scathing, effectively improve
Safety.
It should be pointed out that in the specific implementation, single-blade provided in this embodiment punctures needle shield, in addition to that can answer
Outside blood taking needle, it can be applied in infusion device or other devices for needing to take a blood sample, such as above-mentioned single-blade need to only be worn
Pricker jacket assembly is assemblied on infusion apparatus, so that it may therefore, every to use the single-blade to play the effect of the anti-needle thorn of infusion apparatus
The blood-taking device or infusion device for puncturing needle shield are within the scope of the invention.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
