Embodiment
The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model
Among described scope of embodiments.
In this specification, before syringe needle direction is, after opposite direction is.
Such as Fig. 2-Fig. 7, safe blood-taking needle syringe needle includes：Bounce back blood taking needle, including：Needle stand 3, needle tubing 2, needle guard 1, protection
Body 4, the body of needle stand 3 is that double tridents connect shape, and needle guard 1 is sheathed on outside the front end of needle stand 3, front end inside and the needle tubing 2 of needle stand 3
It is bonded by adhesive, an inner joint is provided with the rear end of needle stand 3, needle stand 3 is snapped in the intracavitary of protective 4.
One end of four springs 39 is fixed in the middle part of the body of needle stand 3, the other end of spring 39 extends to the both ends of needle stand 3, and
It is and more and more remote along the bearing of trend, the distance of spring 39 to needle stand 3.Four springs are generally located in a plane, pin
3 bodies of seat are respectively provided with two springs per side, and this two extend to the both ends of needle stand 3 respectively.Needle stand 3 and spring 39 are similar to butterfly
Shape.
The overall outside for being enclosed on needle stand 3 of protective 4, include the retainer ring 46 at both ends, the retainer ring can be circle, oval
Shape, or polygon ring, in a word, its ring-type generally closed, the shape of actual production can be tetracyclic ring.Both ends
Retainer ring 46 fixed by the intermediate connector 47 of multiple strips, maintain protective 4 overall security and stability.In phase
Space between adjacent intermediate connector 47 is provided with press strip 48, and press strip 48 is altogether provided with two, itself and the spring 39 rearwards extended
Location matches.
Press strip 48 is flexible, and its one end is fixed in retainer ring 46 above, and the other end is provided with inwardly projecting compressing
Portion 41, oppression department 41 preferably coordinate with the rear portion of spring 39.
The end of the spring of each spring 39 extended forward is provided with groove 31, the end of the spring 39 each to extend back
Provided with step 32, retainer ring 46 below is provided with boss 43, boss 43 and groove 31, step 32 at the plane where spring 39
Coordinate.
Axial distance between groove 3, step 32 is more than or equal to the length that syringe needle 2 extends to the outside of protective 4.
In order to facilitate gripping, the outside of protective 4 is provided with handle 42.
In actual production, retainer ring 46 is flat tetracyclic ring, and intermediate connector 47 is two, respectively positioned at upper and lower two
Bottom surface, press strip 48 are respectively provided at two sides.Flat tetracyclic ring helps to fix the plane where spring 39, prevents bullet
Bar 39 is slightly overturn in protective 4.In Fig. 4, in order to remove expression, gap among intermediate connector 47 and press strip 48 compared with
Greatly, in fact, intermediate connector 47 can be very small with the gap among press strip 48, as long as not influenceing the activity of press strip 48.
Its operation principle is：
Before use, such as Fig. 2, needle stand 3 is integrally located inside protective 4, and the boss 43 of retainer ring 46 is stuck in the end of spring 39
Step 32 in, the spring 39 of rear end is fixed；The end of the spring 39 of front end is limited by the retainer ring 46 of front end and press strip 48
System, so, needle stand 3 is overall more stable.
In use, needle guard 1 is removed, it can use, this point is as prior art.
Using finishing, needle tubing 2 can be ensconced in protective 4, be specially：With the press strip 48 of hand extruding both sides, oppression department
41 can extrude the spring 39 to extend back, and referring to Fig. 5, the contact with spring 39 of oppression department 41 can be approximated to be a little to be connect with face
Touch, oppression department 41 can consider to the pressure F of spring 39 has one perpendicular to the surface of spring 39, the axial direction of spring 39 and needle stand 3
Angle, causes pressure F to be decomposed into axial force F 2 and radial load F1, and F1 makes spring 39 become to the flexural deformation of needle stand 3, the bending
Shape can make boss 43 be threaded off with step 32, and the direction of two axial force Fs 2 all backward, can give needle stand 3 one power moved backward；
Meanwhile the spring 39 of bending can also produce a moment of torsion to the fixing end of spring 39, in Fig. 5, the moment of torsion of the spring in left side is suitable
Clockwise, the moment of torsion of the spring on right side is counterclockwise, the effect of two moments of torsion and axial force F 2, can make needle stand 3 to
After have a displacement, the displacement causes the step 32 of spring 39 to go out the boss 43 of protective 4, and the spring 39 to extend back obtains
Freedom, complete to thread off.During being somebody's turn to do, operator only has an action, is exactly to be with the press strip 48 of hand extruding both sides, the action
The cooperation of thumb and forefinger is had an effect, and the palm thumb web of the position behaviour of having an effect, according to ergonomics, it is most to hold that the position, which is had an effect,
Easy, so, it can be achieved easily to thread off.Undoubtedly, the design reduces the burden of medical personnel, and present medical personnel are mostly female
Property, so facilitate them and use.
Then, hand grips protective 4, and a hand gently pulls the flexible pipe that needle stand 3 connects below so that needle stand 3 and
Syringe needle 2 is moved rearwards, and such as Fig. 7, until the groove 31 of the spring 39 of preceding extension blocks boss 43, needle stand 3 is fixed again.This
When, the axial distance of distance that needle stand 3 and syringe needle 2 are moved rearwards between groove 31, step 32, it is sufficient to ensconce syringe needle 2 and protect
In watch box 4, reach safety requirements.
In addition, with the utility model patent of Application No. 201410363854.6 disclosed in a kind of blood taking needle compare, this reality
Reduce a part with new --- saddle, its repertoire can be reached again, meet the condition for reducing omitting elements.Examine
Guide specification：If utility model is compared with prior art, utility model saves one or more key elements (for example, a product
Utility model eliminates one or more parts and components or a method utility model saves one or multi-step process) after, according to
Original repertoire is so kept, or brings unexpected technique effect, then with prominent substantive distinguishing features and significantly
