[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] See also Figures 1 to 3The utility model provides a technical solution: an integrated dispensing syringe, comprising an injection tube 1, one end of the injection tube 1 is movably provided with a needle tube 6 through an adjusting mechanism, the adjusting mechanism comprises a fixed tube 3, the fixed tube 3 is fixedly connected to one end of the injection tube 1, one end of the fixed tube 3 is provided with a rotating sleeve 4 for limited rotation, the interior of the fixed tube 3 is movably provided with a slide plate 8 through a limiting sealing mechanism, the needle tube 6 is fixedly arranged at the center position of the slide plate 8, the outer wall of the needle tube 6 is provided with an external thread, one end of the rotating sleeve 4 is fixedly provided with a plug-in tube 5, through the provided plug-in tube 5, the integrated dispensing syringe can be plugged in with an ordinary needleless syringe, so that the drugs inside them can be mixed conveniently, thereby dispensing medicines.
[0020] In this embodiment, a piston 7 is movably installed inside the injection tube 1, and a piston rod 2 is fixedly provided on one side of the piston 7. A through hole is opened at the center position of one end of the injection tube 1, and the through hole is connected to the interior of the fixed tube 3. The piston 7 is driven by the piston rod 2 to facilitate the suction or discharge of the liquid medicine.
[0021] In this embodiment, the needle tube 6 is screwed together at the center of the rotating sleeve 4 through an external thread, and a needle tip is provided at the outer end of the needle tube 6. Rotating the rotating sleeve 4 facilitates telescopic adjustment of the needle tube 6.
[0022] In this embodiment, the limiting sealing mechanism includes a limiting groove 10, which is symmetrically arranged at the top and bottom of the inner wall of the fixed tube 3. The limiting groove 10 is internally provided with a limiting block 9 for sliding movement. The limiting block 9 is symmetrically fixed at the top and bottom of the slide plate 8. A sealing rubber ring 11 is fixedly arranged on one side of the slide plate 8. A rubber block 12 is fixedly arranged on the top and bottom of the sealing rubber ring 11. The rubber block 12 is fixedly arranged on one side of the limiting block 9. The rubber block 12 is slidingly arranged inside the limiting groove 10. The sealing rubber ring 11 contacts the inner wall of the fixed tube 3. The limiting block 9 and the limiting groove 10 are used to facilitate the limiting of the slide plate 8, so that the slide plate 8 slides inside the fixed tube 3 driven by the needle tube 6. The sealing rubber ring 11 and the rubber block 12 can increase the sealing between the slide plate 8 and the fixed tube 3.
[0023] When the integrated dispensing syringe is used, the rotating sleeve 4 is rotated during use, and the needle tube 6 is driven by the screw connection between the rotating sleeve 4 and the external thread. The limiting groove 10 and the limiting block 9 can limit the slide plate 8, so that the needle tube 6 fixedly connected to the slide plate 8 moves to the outside of the fixed tube 3 under the drive of the rotating sleeve 4, and the needle tube 6 can be telescopically slid inside the fixed tube 3, and the stability of the slide plate 8 and the needle tube 6 is improved, so that the needle tube 6 can be conveniently transferred out of the fixed tube 3, and the dispensing syringe can be used for dispensing. The needle tube 6 can also be adjusted to the inside of the fixed tube 3 by adjusting mechanisms such as the rotating sleeve 4. This avoids harm to medical staff or patients, reduces the risk of infection, improves the safety of the integrated dispensing syringe, and the needle tube 6 cannot be separated from the injection tube 1, and the needle tube 6 will not fall or be lost, and is highly practical; the sealing rubber ring 11 and the rubber block 12 can improve the sealing between the needle tube 6, the slide plate 8 and the fixed tube 3; an ordinary syringe without the needle tube 6 is connected to the syringe through the plug-in tube 5, which facilitates the mixing of drugs between the dispensing syringe and the ordinary syringe, and facilitates the dispensing of drugs. When dispensing, the syringe and the ordinary syringe both draw less than half the capacity of the injection tube 1.
[0024] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
