Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and specifically
Embodiment is described in detail to the utility model.It should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit the utility model.
Blood taking needle as shown in Figure 1 and Figure 2, main inclusion needle stand 1, needle guard 2 and needle cap 4, between described needle stand 1 and needle guard 2
It is slidably socketed, in needle stand 1 head, piercing needle 3 is fixedly connected with bonding way, needle stand 1 is arranged and is fixedly connected with needle stand 1
The first spacing preiection 11 and the second spacing preiection 12.Described the first spacing preiection 11, the second spacing preiection 12 and needle stand 1 it
Between can be to be fixedly connected in integrated molding mode, to ensure the reliability of connecting portion, and processing cost is lower.In needle guard
Setting the 3rd spacing preiection 21 and lock 22 in 2 inner chambers, described first spacing preiection 11 is located at outside lock 22.Described lock
22 one end are fixedly connected with needle guard 2, and the other end is free end.Described the 3rd spacing preiection 21, lock 22 one end and needle guard 2 it
Between can be integrated molding structure, structure is simple, shaping easily, and connecting portion is more safe and reliable.Needle cap 4 and pin
It is tightly connected between seat 1, and needle cap 4 cladding piercing needle 3, piercing needle 3 both can be protected not to be contaminated by needle cap 4, also might be used
Stab the security risks such as medical personnel be effectively prevented before blood sampling operation that piercing needle 3 led to.
Above-mentioned blood taking needle assembling produce when, needle stand 1, piercing needle 3, needle cap 4 after assembling, by needle stand 1 from needle guard 2
Right-hand member penetrates, to realize being slidably socketed between needle stand 1 and needle guard 2.Smooth with respect to the slip of needle guard 2 in order to increase needle stand 1
Property, exhaust hole 24 can be opened up on needle guard 2, described exhaust hole 24 is communicated with needle guard 2 inner chamber, as shown in Figure 1.By row
Vent hole 24 can discharge the gas of needle guard 2 inner chamber in time, be effectively prevented lead to because of gas compression needle stand 1 and needle guard 2 it
Between slip be obstructed.In needle stand 1 with respect in needle guard 2 sliding process, in order to prevent needle stand 1 from excessively slipping in needle guard 2 inner chamber, can
The maximum outside diameter of needle cap 4 to be dimensioned to the maximum inner diameter size more than needle guard 2.In addition, by latching 22 free end
And cooperate positioned at the first spacing preiection 11 on needle stand 1 it is also possible to limit the freedom between needle stand 1 and needle guard 2 well
Sliding stroke, and so that the relative position between needle stand 1 and needle guard 2 is limited.
When carrying out blood sampling operation, directly twist off needle cap 4 it is ensured that piercing needle 3 exposes to needle guard 2, using piercing needle 3
Blood sampling operation can be carried out.Needle cap 4 can directly be bonded on needle stand 1, twist off needle cap 4 with fast and easy and carry out blood sampling behaviour
Make.After the completion of blood sampling, needle stand 1 is made to slide with respect to needle guard 2, until the second spacing preiection 12 is fastened on the 3rd spacing preiection 21
And latch between 22 free ends, now, piercing needle 3 is wrapped by and is limited in needle guard 2 inner chamber, as shown in Figure 2.By lock
22 and second cooperating it can be ensured that piercing needle 3 can not drop out needle guard 2 from needle guard 2 right-hand member between spacing preiection 12
Outside, by cooperating between the second spacing preiection 12 and the 3rd spacing preiection 21 it can be ensured that piercing needle 3 can not be from
Needle guard 2 left end drops out outside needle guard 2, is stabbed medical personnel etc. such that it is able to effectively eliminate by what piercing needle 3 led to
Potential safety hazard.
As shown in Figure 1 and Figure 2, the first described spacing preiection 11, the second spacing preiection 12, the 3rd spacing preiection 21 are straight
Angle is raised, and its cross sectional shape is square；Described lock 22 adopts pyramidal structure lock, relatively large end therein and needle guard
2 are fixedly connected, and relatively small end is free end and points to the 3rd spacing preiection 21, and described lock 22 is located at exhaust hole 24 1
End, such structure so that lock 22 has higher resistance to compression mechanical strength, also make simultaneously lock 22 free end with respect to
Needle guard 2 main part has bigger elastic free degree, is conducive to latching 22 free ends and can more easily cross the second limit convex
Play 12, and improve the reliability that is fixed between needle stand 1 and needle guard 2, so that it is guaranteed that piercing needle 3 is located in needle guard 2 inner chamber,
And then improve the anti-safety of acupuncture reliability of blood taking needle.In the free end of lock 22, barb 23 can be set, and, described barb
Face all can be formed between 23 with the first spacing preiection 11, the second spacing preiection 12 contact, so can increase lock 22 respectively
Contact area and the first spacing preiection 11, the second spacing preiection 12 between, thus be conducive to improving between needle stand 1 and needle guard 2
Locking reliability.
Using the blood taking needle of above-mentioned anti-needling structure, it is a kind of blood taking needle carrying anti-acupuncture defencive function, structure is more
Simply, using also convenient, safe and reliable, and, its special anti-acupuncture that can cancel completely in traditional blood-taking device is protected
Sheath, and then anti-acupuncture protective case can be assembled without independent, it is entirely avoided operator when carrying out blood taking needle assembling operation
Work is led to because blood taking needle is tucked into be difficult to exit in the hollow cavity of anti-acupuncture protective case by imprudence in an assembling process
Operation puzzlement, simplify blood taking needle assembling operation operation, improve the assembling operation efficiency of blood taking needle, make the entirety of blood taking needle
Cost is also able to cheaper.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model it should refer to
Go out, all any modification, equivalent and improvement made within spirit of the present utility model and principle etc., all should comprise
Within protection domain of the present utility model.
