Abstract
The utility model provides a disposable injector with injection, which comprises a needle cylinder, a push rod and a needle head with a sleeve for the needle head, wherein the injector has the functions as an injector and an ampoule, and the injector is directly filled with the injection and has double functions of injection and injection storage. The injector can reduce the operating procedure of nurses, increases work efficiency and reduces the possibility of injection pollution; besides, the injector dispenses with the glass ampoule and saves cost.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly disposable syringe.
Reuse for fear of syringe and to cause that cross infection and infectious disease propagate, hospital, the family syringe that uses of having an injection all adopts disposable plastic injector usually at present, and its employed injection is all adorned with glass ampule.During injection, need earlier to knock the ampoule mouth open, inhale processes such as injection the ampoule sterilization, operate more numerous, the injection vulnerable to pollution.Be exactly the workload that has increased when the nurse injects in addition, work efficiency is not high, when particularly meeting first-aid patients, incurs loss through delay rescue time.
The purpose of this utility model provides a kind of disposable syringe that contains injection.
Technical solution of the present utility model is such: the function of syringe and ampoule is integrated, injection is directly packed in the syringe, make syringe have the dual-use function of injection and storage injection.
Description of drawings:
Accompanying drawing 1 is for containing the disposable syringe structural representation of injection;
Accompanying drawing 2 is the syringe cylinder structure sketch map;
Accompanying drawing 3 is the right view of syringe;
Accompanying drawing 4 is for having the needle head structure sketch map of pinhead sleeve;
Accompanying drawing 5 is the pusher structure sketch map;
Accompanying drawing 6 is the A-A cutaway view.
Now in conjunction with the accompanying drawings this utility model is made detailed description:
This syringe comprises syringe 2, push rod 3 and has the syringe needle 7 of pinhead sleeve 6, is processed with external screw thread on the syringe needle link 4 of syringe 2, and syringe needle link 4 adopts thread seal to be connected with block 1.The corresponding female thread that matches with external screw thread on the syringe needle link 4 that in the tail end hole of syringe needle 7, is processed with.Tail end at syringe 2 is provided with a breach 5.Can play quantitative effect and can limit the projections 8 that syringe 2 and push rod 3 move each other again what be provided with on the push rod 3 that breach 5 on one and syringe 2 tail ends matches, decide on the injection dosage of being adorned in the syringe 2 position of projection 8 on push rod 3, after the breach 5 on projection on the push rod 38 and syringe 2 tail ends combines, in the syringe 2 remaining space just in time can the fill aequum injection.The cross sectional shape of the projection 8 on the cross sectional shape of the breach 5 on syringe needle 2 tail ends and the push rod 3 is the same, can be designed to rectangle or trapezoidal.
Behind the injection of the ormal weight of packing in the syringe 2, cover block 1, the syringe needle 7 and the syringe 2 one that will have pinhead sleeve 6 are then reinstated the plastic bag encapsulation.
The operation sequence that the disposable syringe that use contains injection can reduce the nurse when injecting is increased work efficiency, and reduces the liquid medicine injection opportunities for contamination.Also cancel glass ampule in addition, saved expense.
