Abstract
The utility model relates to a self-destructed disposable syringe. After an ordinary disposable sterilized syringe is used, the structure and the shape are not changed, the ordinary disposable sterilized syringe is easy to be repeatedly used by people, and viruses are infected. Thus, the utility model provides a disposable sterilized syringe which is mainly composed of an outer sleeve (1), a push rod (2), a piston (3) and a liquid outlet (4), wherein, the front end of the push rod (2) is provided with a locking head (5) which is in a tapered structure, the rear end of the liquid outlet (4) is provided with a step (6), thus the push rod (2) can not be retreated because the locking head (5) of the front part of the push rod is locked by the step (6) of the liquid outlet of the outer sleeve after injection is finished, and simultaneously the utility model can not be reused. The appearance, the size and the injection mode of the self-destructed disposable syringe provided by the utility model are the same to the appearance, the size and the injection mode of the ordinary syringe, the utility model can not be repeatedly used by the change of the internal structure, the infection of lethal viruses is avoided, and virus diffusion is reduced.
Description
Technical field
This utility model relates to the disposable syringe technical field, is specifically related to a kind of Single-Use Auto-Disable Syringes.
Background technology
According to conventional method, after common disposable sterilized syringe used, its structure, shape were reused by the people easily without any change, virus spread.Add up according to hygiene department, at present, only used syringe just has 7～8 tons every day in the medical institutions in Shanghai, the total amount in 1 year is roughly 2500 tons, but neither one really meets the specialization disposal mechanism and the place of environment protection emission and health and epidemic prevention requirement so far, the hidden danger of disposable syringe management mainly concentrates on rural health institute, the infirmary of factory and school and individual rash institute, individual's user, these focal pointes are not unmake after using disposable syringe, the existence of the phenomenon of not sterilizing shows that disposable syringe has the reusable possibility of the society of inflow.
Summary of the invention
The purpose of this utility model just is to change the deficiency of the disposable sterilized syringe of present use, and a kind of Single-Use Auto-Disable Syringes is provided.
The Single-Use Auto-Disable Syringes that this utility model provides mainly is made up of several parts such as overcoat, push rod, piston, liquid outlets.Wherein, the locking head that one tapered structure is arranged foremost of described push rod, and one thrust surface step is arranged at the back-end location of described liquid outlet, like this, when injection is finished, push rod can not retreat because anterior locking head is pinned by the step at overcoat liquid outlet place, and this moment, syringe can't reuse.
The profile of the Single-Use Auto-Disable Syringes that this utility model provides, size, injection system are identical with ordinary syringe, and it can't be reused by the change of internal structure, has prevented the infection of mortality virus, has reduced the diffusion of virus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Figure 1A portion partial enlarged drawing.
Specific embodiments
Shown in Fig. 1-2, the Single-Use Auto-Disable Syringes that this utility model provides mainly is made up of several parts such as overcoat 1, push rod 2, piston 3, liquid outlets 4, and described push rod 2 can drive piston 3 and move forward and backward.Wherein, the front end of described push rod 2 has the locking head 5 of a tapered structure, and in the rear end of described liquid outlet 4 step 6 is arranged, like this, when injection was finished, push rod 2 was owing to anterior locking head 5 is pinned by the step 6 at overcoat liquid outlet 4 places, can not retreat, this moment, syringe can't reuse.
In addition, overcoat 1 rear side of the Single-Use Auto-Disable Syringes that this utility model provides has a limited block 7 that links to each other with described push rod 2, when described push rod 2 drives piston 3 reaches, because limited block 7 effects, stop during at a distance of 1mm from overcoat 1 bottom in the cone locking of push rod 25, guarantee that push rod 2 can not be lockable, easy to exhaust and take out medicinal liquid.
When injection is near completion, push rod 2 forward locking head 5 male cone (strobilus masculinus)s contact with overcoat 1 anterior inner conical surface, push rod 2 continues forward, this moment, medicinal liquid released from the liquid outlet 4 of overcoat 1 front end, finish until injection, push rod 2 can not retreat because anterior locking head 5 is pinned by the step 6 of overcoat 1 place's liquid outlet 4, and this moment, syringe can't reuse.
Also have, this utility model has two pipe protection measures, in case reuse once more.As shown in Figure 2, there is fracture port 8 cone locking described in the utility model 5 rear end, slightly firmly force to pull back push rod 2 as user, this moment is because fracture port 8 place's stress concentration, promptly broken, locking head 5 is stuck in the liquid outlet 4 of overcoat 1, can not continue water outlet.As shown in Figure 1, there is bleeder port 9 at push rod described in the utility model 2 centers, when fracture port 8 recited above fractures, intermediary bleeder port 9 communicates in the hole at the piston 3 bearing-surface places of push rod 2, sealing area communicates with ambient atmosphere, loses sealing function, and this moment, syringe can not continue to use.
Claims (4)
