Abstract
The utility model relates to an ampoule of a needle free syringe, which comprises an outer sleeve, a core bar and a piston. The ampoule of the needle free syringe is characterized in that a front external thread is arranged at the front end of the outer sleeve, a micro pore is arranged in the center of the outer sleeve, a rear external thread is arranged at the rear end of the outer sleeve, the piston is arranged at the front end of the core bar in the outer sleeve, and a handle is arranged at the rear end thereof. When the ampoule is used, medicine liquor is sucked into the outer sleeve, the external thread of the outer sleeve is connected with the internal thread of a high-pressure triggering device (the high-pressure triggering device is applied as a separate case), the micro pore at the front end of the outer sleeve is propped onto skin, and after the switch on the high-pressure triggering device is pressed, the medicine liquor in the outer sleeve can be injected into the hypodermis of the human body at high speed by the high pressure in the high-pressure triggering device, therefore, the ampoule of the needle free syringe can not generate damage and ache to the human body, which is the ideal substitute of the prior syringe.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of needleless injector ampoule.
Background technology
At present, known syringe commonly used clinically generally all is made up of overcoat, core bar and syringe needle, during injection, syringe needle is will prick the people subcutaneous or intramuscular, if use it once in a while, though human body is had injury, but there is no big harm, and concerning diabetics one day one pin even two pins, though its syringe needle is tiny, the injury that human body is caused also is huge, also well imagines to the misery that the patient causes but year in and year out.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of needleless injector ampoule that just can inject without syringe needle is provided, and its simple structure is easy to use.
The technical scheme that its above-mentioned technical problem that solves this utility model adopts is: a kind of needleless injector ampoule, it comprises overcoat, core bar and piston, it is characterized in that: the front end of overcoat is provided with preceding external screw thread, the centre is provided with micropore, the rear end of overcoat is provided with the back external screw thread, core bar front end in the overcoat is provided with piston, and the rear end is provided with handle.During use medicinal liquid is extracted in the overcoat, the external screw thread of overcoat and the female thread of high pressure firing device (application of high pressure firing device separate case) are joined, the micropore of overcoat front end is pushed up on the skin, press the switch on the dynamic high-pressure firing device, medicinal liquid in the overcoat will be subcutaneous to be injected into human body at a high speed by the high pressure in the high pressure firing device, to human zero damage, no pain, be the ideal substitute of existing syringe.
The beneficial effects of the utility model are: simple in structure, easy to operate, to human zero damage, no pain, and be the ideal substitute of existing syringe.
