Specifically, the export of play liquid check valve with the laminating of syringe needle connecting pipe, the import of going out the liquid check valve sets up the liquid medicine intraduct, the play liquid end of drainage tube with the medial surface coincidence of going out the liquid check valve, the export of feed liquor check valve with the feed liquor end laminating of drainage tube, the import of feed liquor check valve sets up inside the installation cover, the import and the atmosphere intercommunication of the check valve of admitting air, the export of the check valve of admitting air with the air inlet intercommunication of intake pipe.
The beneficial effects of the utility model reside in that:
the utility model relates to a novel syringe is through connecting the medicament bottle on the liquid medicine pipe, and it is intraductal to drain to the liquid medicine between with the medicament through the drainage tube, when carrying out a lot of injections, do not need repeated many times to extract the medicament in inserting the syringe needle to the medicament bottle, and convenient to use has the value of popularization and application.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, the utility model relates to a novel injector, which comprises a medicine liquid tube 1, an injection piston 4, an injection push-pull rod 3, a needle head connecting tube 2, a drainage tube 7, a liquid outlet one-way valve 5, a liquid inlet one-way valve 8, an installation sleeve 6, an air inlet one-way valve 9, a gas tube 10 and a medicine bottle 11, wherein the needle head connecting tube 2 is arranged at the front end of the medicine liquid tube 1, the injection piston 4 is arranged in the medicine liquid tube 1 and can slide back and forth along the medicine liquid tube 1, the injection push-pull rod 3 is fixedly connected with the rear side surface of the injection piston 4, the lower end of the installation sleeve 6 is fixedly connected with the outer side wall of the medicine liquid tube 1, the upper end of the installation sleeve 6 is detachably connected with the opening of the medicine bottle 11 through threads, the two ends of the drainage tube 7 are respectively communicated with the installation sleeve 6 and the medicine liquid tube 1, the liquid outlet one-way valve 5 is fixedly arranged, the inner of trachea 10 sets up in medicament bottle 11, the outer end of trachea 10 passes installation cover 6 and communicates with the atmosphere, admit air check valve 9 sets up the outer end at trachea 10, the export of going out liquid check valve 5 and the laminating of syringe needle connecting pipe 2, the import of going out liquid check valve 5 sets up inside liquid medicine pipe 1, the play liquid end of drainage tube 7 coincides with the medial surface of going out liquid check valve 5, the export of feed liquor check valve 8 and the laminating of the feed liquor end of drainage tube 7, the import of feed liquor check valve 8 sets up inside installation cover 6, the import of the check valve 9 that admits air communicates with the atmosphere, the export of the check valve 9 that admits air communicates with the air inlet of intake pipe 10.
The working principle of the utility model is as follows:
