Abstract
The utility model relates to a self-priming syringe which comprises an injection tube, a piston and a piston rod, wherein, a fixed magnet is fixed on the front end of the injection tube; a movable magnet which is homopolar with the fixed magnet is fixed on the piston rod close to the rear end of the piston; a portable circular lug on the rear end of the injection tube is provided with a semi-circular limit snap gauge; the limit snap gauge is provided with a threaded rod; the threaded rod is provided with a limit nut; scales are arranged outside the injection tube. The self-priming syringe has the advantages that during use, the piston is pushed to the bottom end of the injection tube; a needle tip is punctured into a medicine bottle or a drug dispensing vessel; the piston rod is released; the use is convenient; and the self-priming syringe has automatic medicine sucking function, saves time and labor, reduces the labor intensity of the medical staff, and prevents the waste of liquid medicine.
Description
Technical field:
This utility model relates to technical field of medical instruments, particularly a kind of self-suction syringe with self-suction function.
Background technology:
At present, in medical and health industry, the nursing staff is when injecting or making up a prescription, need draw medicine with syringe, for protecting from infection, the nursing staff will be on the other hand fixing medicine bottle, a hand-held syringe, the pulling piston is drawn medicine, more for a long time, this operational approach can make the aching and limp pain of nursing staff's arm, troublesome poeration at medicine, and waste time and energy, increased nursing staff's working strength.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provide a kind of simple in structure, easy to use, can inhale medicine automatically and avoid the self-suction syringe of liquid waste.
To achieve these goals, this utility model provides a kind of self-suction syringe, comprise injection tube, piston and piston rod, wherein, the fixed magnet piece that has through hole in the middle of described injection tube Inner Front End is set with, be set with movable magnet piece on the described piston rod near described piston rear end with described fixed magnet piece homopolarity, the Handheld Division circular protrusions of described injection tube rear end is provided with semicircle spacing clamp, described spacing clamp is provided with threaded rod, described threaded rod is provided with stop nut, described injection tube be provided with graduation mark in appearance.
The outstanding advantage of this utility model is: simple in structure, during use, piston is pushed into the injection tube bottom, syringe needle thrust medicine bottle or the vessel that make up a prescription in, the release plunger bar gets final product, easy to use, because fixed magnet piece and movable magnet piece belong to homopolarity, so the movable magnet piece can be under the repulsion of fixed magnet piece away from, drive piston and piston rod simultaneously and outwards move, make and produce negative pressure in the injection tube, thereby medicinal liquid is sucked in the injection tube, have automatic suction medicine function, time saving and energy saving, reduce medical workers; The Handheld Division circular protrusions of injection tube rear end is provided with semicircle spacing clamp, in addition, also is provided with threaded rod on the spacing clamp, and threaded rod is provided with stop nut, effectively avoids liquid waste.
Description of drawings:
Fig. 1 is the overall structure front view of this utility model embodiment.
Fig. 2 is the side view of Fig. 1.
The specific embodiment:
When embodiment of the present utility model implements its design agents mechanism comprise injection tube 1, fixed magnet piece 2, cold 3, the movable magnet piece 4 of living, piston rod 5, spacing clamp 6, threaded rod 7, stop nut 8 and graduation mark 9.Wherein, the fixed magnet piece 2 that has through hole in the middle of injection tube 1 Inner Front End is set with, be set with movable magnet piece 4 on the piston rod 5 near piston 3 rear ends with fixed magnet piece 2 homopolarities, the Handheld Division circular protrusions of injection tube 1 rear end is provided with semicircle spacing clamp 6, spacing clamp 6 is provided with threaded rod 7, threaded rod 7 is provided with stop nut 8, injection tube 1 be provided with graduation mark 9 in appearance.
Self-suction syringe of the present utility model, during use, piston 3 is pushed into injection tube 1 bottom, the syringe needle that will be arranged on injection tube 1 front end then thrust medicine bottle or the vessel that make up a prescription in, release plunger bar 5 gets final product, easy to use, because fixed magnet piece 2 and movable magnet piece 4 belong to homopolarity, so movable magnet piece 4 can be under the repulsion of fixed magnet piece 2 away from, drive piston 3 and piston rod 5 simultaneously and outwards move, make and produce negative pressure in the injection tube 1, thereby medicinal liquid is sucked in the injection tube 1, have automatic suction medicine function, time saving and energy saving, reduce medical workers; The Handheld Division circular protrusions of injection tube 1 rear end is provided with semicircle spacing clamp 6, can drive piston 3 and the outwards mobile distance of piston rod 5 by restraint magnet piece 4, thereby prevent that piston 3 breaks away from away, causes liquid waste in injection tube 1; Spacing clamp 6 is provided with threaded rod 7, threaded rod 7 is provided with stop nut 8, when in not needing, being filled medicinal liquid with injection tube 1, can be by being screwed into stop nut 8 forward, simultaneously can push away piston rod 5 moves forward, contrast injection tube 1 apparent graduation mark 9, when stop nut 8 is screwed onto suitable position, piston 3 is pushed into injection tube 1 bottom, the syringe needle that will be arranged on injection tube 1 front end then thrust medicine bottle or the vessel that make up a prescription in, release plunger bar 5, piston 3 and piston rod 5 move under the drive of movable magnet piece 4 to the back-end, when piston rod 5 is run into stop nut 8, piston rod 5 and piston 3 can't continue to move backward, thereby make the medicinal liquid that has sucked requirement in the injection tube 1, effectively control the amount of medicinal liquid, avoid the waste of medicinal liquid, easy to operate.
