Technical field

The utility model relates to technical field of medical equipment, and in particular to a kind of coupling type self-destroyed syringe.

Background technique

Syringe is a kind of common medical devices, China on the market mass selling and clinically largely use Syringe is still common disposable syringe, since it does not have self-destructed function, is easy to make by illegal recycling, repeatedly With generation cross-infection easily causes transmission.

Utility model content

The purpose of the utility model is to overcome the above-mentioned problems in the prior art, it is simple to provide a kind of structure, if Meter is novel, the low coupling type self-destroyed syringe of manufacturing cost.

To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions :

A kind of coupling type self-destroyed syringe, including syringe needle, syringe, piston, connecting rod and handle, the piston are located at syringe Interior top, the piston lower surface are fixed with the annulus of standing, match with the annulus and are equipped with hook, the hook It is inserted in annulus from right side, the hook is irony, and the bottom axis of the hook connects in the top of connecting rod, the left side of the hook Equipped with side wall, the right side of the hook is equipped with magnet, offers safe lockhole on the barrel at the syringe lower opening, described Through-hole is offered in connecting rod, the safe lockhole and through-hole are run through by a night bolt.

Further, the height of the side wall is greater than the diameter of annulus.

Further, the magnet is identical as the size structure of side wall.

The utility model is when in use: then extraction night bolt first pulls handle to draw injection, then pushes hand Handle starts to inject, and when driving handle, hook can be detached from annulus, and be adsorbed on magnet, cause the utility model can not be again Using to realize self-destruction.

The utility model has the following beneficial effects: the utility model is novel in design, structure is simple, and manufacturing cost is low, Wu Fachong It is multiple to use, it is therefore prevented that the transmission occurred by cross-infection.

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face will combine the attached drawing in the utility model embodiment, carry out to the technical scheme in the embodiment of the utility model clear, complete Ground description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Base In the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts There are other embodiments, fall within the protection scope of the utility model.

Embodiment 1

As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model is a kind of coupling type self-destroyed syringe, including syringe needle 1, syringe 2, piston 3, connecting rod 4 and handle 5, the piston 3 are located at the top in syringe 2, and 3 lower surface of piston is fixed with vertical The annulus 6 risen matches with the annulus 6 and is equipped with hook 7, and the hook 7 is inserted in annulus 6 from right side, and the hook 7 is iron Matter, the bottom axis of the hook 7 connect on the top of connecting rod 4, and the left side of the hook 7 is equipped with side wall 8, the right side of the hook 7 Side is equipped with magnet 9, offers safe lockhole 10 on the barrel at 2 lower opening of syringe, offers in the connecting rod 4 logical Hole 11, the safe lockhole 10 and through-hole 11 are run through by a night bolt 12.

Further, the height of the side wall 8 is greater than the diameter of annulus 6.

Embodiment 2

As another embodiment of the utility model, the coupling type self-destroyed syringe of the present embodiment and the hook of embodiment 1 The structure of formula self-destroyed syringe is essentially identical, the difference is that, the magnet 9 is identical as the size structure of side wall 8.

The utility model is when in use: then extraction night bolt 12 first pulls handle 5 to draw injection, with pusher Fixed handle 5 starts to inject, and when driving handle 5, hook 7 can be detached from annulus 6, and be adsorbed on magnet 9, leads to the utility model It can not reuse to realize self-destruction.

The utility model is novel in design, and structure is simple, and manufacturing cost is low, can not reuse, it is therefore prevented that because of cross-infection The transmission of generation.
