Out, perhaps gas is sucked when core bar is pushed into from syringe front end aperture by liquid or gas liquid when core bar is extracted
It squeezes out, is called injection with this process that syringe and syringe needle extracted or injected gas or liquid, mainly to inject
Medical fluid or drawing liquid.Existing traditional syringe is made of syringe needle, needle tubing and needle core, and syringe needle passes through the nipple card of needle tubing front end
Dress, to carry out medical therapy or extract blood, the syringe needle of this syringe is connect with needle tubing to be easy to lay down, after replacing syringe needle
It is reused, therefore existing syringe cannot actively solve the problems, such as that syringe is prevented to be reused from structure, it is existing
Syringe when drawing injection is easy that stopper rod extraction is led to liquid waste because of not paying attention to.
Utility model content
In order to overcome the shortcomings of existing injector technology, the utility model provides a kind of anti-dropout syringe.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of anti-dropout syringe, including syringe
And push rod, the push rod section are in cross, described push rod one end is provided with piston, and the other end is provided with by hand, the push rod
One end of upper fixed piston is sheathed in syringe, described to be exposed to outside syringe by hand one end, and the push rod is set close to piston one end
It is equipped with bending section, retaining ring is provided between the bending section and piston, described syringe one end is provided with needle stand, other end opening
It is provided with wing plate, the sliding block between the wing plate, the wing plate side is provided with guide groove, and limited post, institute are arranged on the sliding block
Limited post is stated to connect by connecting bridge with guide groove one end.
It is V-type groove that another embodiment according to the present utility model, which further comprises bending section,.
It is arc panel that another embodiment according to the present utility model, which further comprises wing plate,.
Another embodiment according to the present utility model, further comprise syringe opening be symmetrically arranged with two blocks of wing plates and
Sliding block.
Another embodiment according to the present utility model further comprises being symmetrical arranged on sliding block there are two limited post.
Another embodiment according to the present utility model further comprises the outer ring spacing between the guide groove of wing plate greater than interior
Enclose spacing.
The beneficial effects of the utility model are: the utility model passes through the gear being arranged in sliding block and syringe between wing plate
Circle matches, and can effectively prevent syringe that push rod is pulled out to the liquid waste for leading to extract accidentally when extracting medical fluid, pass through
Connecting bridge can thoroughly prevent to re-use post sales, to a kind of sense of security of patient having an injection of seeing a doctor is needed, patient can be made to trust
It uses, and the patient people that sees with one's own eyes when injecting can be made using one cannot to repeat the syringe reused, bending section can be just
It fractures in by push rod, syringe is further prevented to reuse.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of anti-dropout syringe, including syringe 1 and push rod 2, it is described
2 section of push rod is in cross, and described 2 one end of push rod is provided with piston 3, and the other end is provided with by hand 4, fixed on the push rod 2
One end of piston 3 is sheathed in syringe 1, described to be exposed to outside syringe 1 by 4 one end of hand, and the push rod 2 is set close to 3 one end of piston
It is equipped with bending section 5, retaining ring 6 is provided between the bending section 5 and piston 3, bending section 5 is V-type groove, described 1 one end of syringe
It is provided with needle stand 7, other end opening is provided with wing plate 8, and the utility model passes through sliding block 9 and the needle being arranged between wing plate 8
Retaining ring 6 in cylinder matches, and can effectively prevent syringe that push rod 2 is pulled out to the medical fluid for leading to extract accidentally when extracting medical fluid
Waste, bending section 5 can further prevent syringe to reuse convenient for push rod fractures.
As shown in Fig. 2, the sliding block 9 between the wing plate 8,8 side of wing plate is provided with guide groove 10, on the sliding block 9
Limited post 11 is set, and the limited post 11 is connected by connecting bridge 12 with 10 one end of guide groove, and wing plate 8 is arc panel, passes through connection
Bridge 12 can thoroughly prevent to re-use post sales, and to a kind of sense of security of patient having an injection of seeing a doctor is needed, patient can be made, which to trust, to be made
With, and the patient people that sees with one's own eyes when injecting can be made using one cannot to repeat the syringe reused, 1 opening of syringe is symmetrical
It is provided with two blocks of wing plates 8 and sliding block 9, is symmetrical arranged on sliding block 9 there are two limited post 11, the outer ring between the guide groove 10 of wing plate 8
