Abstract
The utility model discloses a magnetic-attraction type positioning non-residue reuse-preventive disposable syringe, which consists of a needle barrel (1), a needle head mounting seat (2), a piston (3) and a piston handle (4). The needle head mounting seat (2) is disposed at the front end of the needle barrel (1). The magnetic-attraction type positioning non0alowance reuse-preventive disposable syringe is characterized in that a positioning magnetic ring (5) is arranged in the needle barrel (1), a stop thorn (6) is arranged on the outer wall of the positioning magnetic ring (5), a sliding magnetic ring (7) is disposed on the outer wall of the needle barrel (1), a push-injection inner core (8) is disposed at the center of the piston (3), a secondary push handle (9) is arranged in the piston handle (4), and an upper push-injection inner core (8) is fixed at the front end of the secondary push handle (9). The magnetic-attraction type positioning non-residue reuse-preventive disposable syringe not only is simple in structure and convenient in use, but also can realize quick quantitative extraction, does not have residue during injection, further can prevent from being used again for injection, not only can avoid wasting liquid medicine, but also avoid excessive injection, and further can prevent cross injection.
Description
Technical field
This utility model relates to a kind of improvement of vaccine syringe, and specifically a kind of magnetic-type location does not have the anti-reuse shot device of surplus, is applicable to the immunization programs for children inoculation.
Background technology
For the immunization programs for children inoculation, normally adopt disposable syringe, comprise that syringe, syringe needle mount pad, piston, piston handle constitute, to inject by extracting quantitative medicinal liquid, it is quantitatively realized to quantitative scale by the pulling piston.The deficiency of this syringe is: the one, and quantitative scale when piston is evacuated to quantitative scale, needs slow-down not with accurate location, also will bow one's head to observe, and influences extraction speed; The 2nd, can reclaim epidemic prevention utilization once more, cause malfeasant generation; The 3rd, because the front end of piston is an arcwall face, so the medicinal liquid at front end needle stand intracavity can not be released, cause the waste of medicinal liquid, perhaps the injection volume deficiency causes immune success rate to descend, under this shape condition, often quantitatively solve with improving, and improve quantitatively, in case control badly, then cause injury to the child.
Summary of the invention
The purpose of this utility model is to provide a kind of and can quantitatively extracts fast, also can capacity not have residue, and can also prevent to reclaim the magnetic-type location of repeating to remake injection does not have the anti-reuse shot device of surplus.
For reaching above purpose, the technical scheme that this utility model adopted is: this magnetic-type location does not have the anti-reuse shot device of surplus, by syringe, the syringe needle mount pad, piston, piston handle constitutes, the syringe needle mount pad is located at the front end of syringe, and be one, the inner chamber of its syringe needle mount pad and the intracavity inter-connection of syringe, piston handle is fixed on the rear end of piston, piston inserts in the syringe, it is characterized in that being provided with in syringe the location magnet ring, is provided with only agnail on the outer wall of location magnet ring, on the outer wall of syringe, be provided with the slip magnet ring, be provided with at the center of piston and inject inner core, be provided with secondary in the piston handle and push away handle, secondary pushes away the front end of handle and injects inner core on fixing.This utility model is also implemented by following measure: described diameter of injecting inner core is consistent with the intracavity diameter of syringe needle mount pad, length equal the length of syringe needle mount pad and piston thickness with.
The beneficial effects of the utility model are: compare with the ordinary syringe vaccinate with present, not only simple in structure, easy to use, and can extract fast quantitatively, do not have surplus in the injection, can also prevent to reclaim and repeat to remake injection, both avoided liquid waste, it is excessive can not inject again, can also prevent cross infection.
Description of drawings
Fig. 1, be that axis of no-feathering of the present utility model is to office's cross-sectional schematic.
Fig. 2, for this utility model along the enlarged diagram of analysing and observe of A-A.
The specific embodiment
Make this utility model with reference to Fig. 1,2.This magnetic-type location does not have the anti-reuse shot device of surplus, by syringe 1, syringe needle mount pad 2, piston 3, piston handle 4 constitutes, syringe needle mount pad 2 is located at the front end of syringe 1, and be one, the intracavity inter-connection of the inner chamber of its syringe needle mount pad 2 and syringe 1, piston handle 4 is fixed on the rear end of piston 3, piston 3 inserts in the syringe 1, it is characterized in that in syringe 1, being provided with location magnet ring 5, on the outer wall of location magnet ring 5, be provided with only agnail 6, on the outer wall of syringe 1, be provided with slip magnet ring 7, slide to the front portion of syringe 1 by slip magnet ring 7, the location magnet ring 5 that drives in the syringe 1 slides to the front portion of syringe 1, till the quantitative scale of determining, at this moment, carry piston 3 on getting final product fast, suck medicinal liquid, when location magnet ring 5 is touched on the top of piston 3, reach suction quantitatively, because location magnet ring 5 is provided with only agnail 6, so location magnet ring 5 can not take out, thereby can prevent to reclaim reuse, is provided with at the center of piston 3 and injects inner core 8, be provided with secondary in the piston handle 4 and push away handle 9, secondary pushes away the front end of handle 9 and injects inner core 8 on fixing, inserts the intracavity of syringe needle mount pads 2 by injecting inner core 8, and reaching medicinal liquid does not have remaining purpose.This utility model is also implemented by following measure: described diameter of injecting inner core 8 is consistent with the intracavity diameter of syringe needle mount pad 2, length equal the length of syringe needle mount pad 2 and piston 3 thickness with.
When using this utility model, untapped magnetic-type location does not have the anti-reuse shot device of surplus, location magnet ring 5 is in the seat end of syringe 1, during use, at first promote to the front portion, drive location magnet ring 5 and promote to the front portion by slip magnet ring 7, till the quantitative scale of determining, the intracavity that piston 3 is pushed into syringe 1 then, inserts in the medicinal liquid foremost, pulling piston 3, get final product the suction medicinal liquid, reach quantitatively, during injection, push piston handle 4 earlier, after piston 3 is shifted the end onto, push secondary again and push away handle 9, the medicinal liquid of syringe needle mount pad 2 intracavity is injected again finished.
