Abstract
A self-locking type disposable syringe comprises a needle cylinder (1). The needle cylinder (1) is internally provided with a push rod (2), and the back end of the push rod (2) is fixedly connected with a push handle (3). The self-locking type disposable syringe is characterized in that the back portion of the push rod (2) is fixedly connected with a connecting rod (4) which is perpendicular to the push rod (2), the other end of the connecting rod (4) is fixedly connected with a synchronous push rod (5) which is parallel to the push rod (2), the other end of the synchronous push rod (5) is fixedly connected with an elastic buckle tooth (8) which is connected to the other end of the synchronous push rod (5) in a splay mode, the outer face of the needle cylinder (1) is fixedly connected with a sleeve (6) which is parallel to the needle cylinder (1), an inner cavity (7) is formed in the middle of the sleeve (6), the front portion of the synchronous push rod (5) and the elastic buckle tooth (8) are located inside the inner cavity (7), and the overall width of the spread elastic buckle tooth (8) is larger than the diameter of the inner cavity (7).
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of self-locking disposable injector.
Background technology
For safety and sanitation, the syringe that hospital is used to human and animal's injectable drug mostly is disposable product, these medicines mostly are prophylactic vaccine, manufacturer's sale of dispatching from the factory again after medicine is sealed up for safekeeping in syringe, some lawless people, in order to seek illegal profit, extract other medicinal liquids after this class syringe is reclaimed again, mix the spurious with the genuine and reuse, with this, cheat consumer, the inevitable like this safety that directly threatens human and animal.
Utility model content
This utility model, for deficiency, provides a kind of safe self-locking disposable injector that uses.
The technical scheme that this utility model solves the problems of the technologies described above is as follows:
A kind of self-locking disposable injector, comprise syringe, in syringe, be provided with push rod, putting back-end is fixedly connected with and pushes away handle, it is characterized in that, push rod rear portion is fixedly connected with connecting rod, connecting rod and push rod are orthogonal, and the connecting rod other end is fixedly connected with synchronous push rod, and synchronous push rod and push rod are parallel to each other, the synchronous push rod other end is fixedly connected with elasticity buckle teeth, and elasticity buckle teeth is "eight" shape and is connected to the synchronous push rod other end; Syringe outside is fixedly connected with sleeve, and sleeve and syringe be arranged in parallel, in the middle of sleeve, is inner chamber, and front portion and the elasticity buckle teeth of synchronous push rod are positioned at intracavity, and the overall width after elasticity buckle teeth opens is greater than the diameter of inner chamber.
This utility model Elastic buckle teeth, synchronous push rod are connected as a whole with connecting rod with push rod, when push rod is pushed ahead, elasticity buckle teeth also travels forward, and at medicine, is about to inject when complete, and elasticity buckle teeth stretches out from barrel forward end, and elasticity buckle teeth opens, be positioned at barrel forward end, rollback backward, illegally utilizes after stoping lawless people to reclaim syringe with this, avoid bringing threat to humans and animals, so this utility model is used safety.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is another kind of structural representation of the present utility model.
In accompanying drawing:
1, syringe; 2, push rod; 3, push away handle; 4, connecting rod; 5, synchronous push rod; 6, sleeve; 7, inner chamber; 8, elasticity buckle teeth.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining this utility model, is not intended to limit scope of the present utility model.
As depicted in figs. 1 and 2, a kind of self-locking disposable injector, comprise syringe 1, be provided with push rod 2 in syringe 1, push rod 2 rear ends are fixedly connected with and push away handle 3, push rod 2 rear portions are fixedly connected with connecting rod 4, connecting rod 4 is orthogonal with push rod 2, and connecting rod 4 other ends are fixedly connected with synchronous push rod 5, and synchronous push rod 5 is parallel to each other with push rod 2, synchronous push rod 5 other ends are fixedly connected with elasticity buckle teeth 8, and elasticity buckle teeth 8 is "eight" shape and is connected to synchronous push rod 5 other ends; Syringe 1 outside is fixedly connected with sleeve 6, and sleeve 6 be arranged in parallel with syringe 1, in the middle of sleeve 6, is inner chamber 7, and front portion and the elasticity buckle teeth 8 of synchronous push rod 5 are positioned at inner chamber 7, and the overall width after elasticity buckle teeth 8 opens is greater than the diameter of inner chamber 7.
