Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Examples
As shown in fig. 1-3, a novel medicine injection device, like the existing injector, comprises a syringe 1 and a piston member 2 matching with the syringe 1, wherein the left end of the syringe 1 is provided with a protruding connecting cylinder 3, so that medical personnel can connect the connecting cylinder 3 with an external extension tube or a needle according to different requirements, and the piston member 2 comprises an integrally formed piston head 21, a rod body 22 and a hand-held part 23. In the initial state, the piston head 21 and the rod 22 are located inside the syringe 1, and the piston member 2 can be moved in the axial direction of the syringe 1 by applying a force to the external holding portion 23, and the piston member 2 cannot be completely removed from the inside of the syringe 1. The concrete expression is as follows: when the piston head 21 is moved away from the left end of the cylinder 1, external liquid or gas may be sucked into the cylinder 1, and when the piston head 21 is moved toward the left end of the cylinder 1, liquid or gas inside the cylinder 1 may be discharged. The utility model discloses still make new design to cylinder 1 and piston spare 2 for the cylinder can carry out the shading to inside medicine, and can improve when reducing medical personnel's injection error and join in marriage the dose accuracy.
Specifically speaking, syringe 1 outer wall is equipped with the scale mark, and its scale mark volume increases from syringe 1 left end to syringe 1 right-hand member in proper order, and the in-process of the configuration liquid medicine of medical personnel before the injection of being convenient for can master specific dosage according to the scale mark on syringe 1 wall, has improved the accuracy of dispensing. Also be equipped with corresponding scale mark on the 2 body of rod 22 of piston spare, the difference is, the scale mark on the 2 body of rod 22 of piston spare is reduced by its piston head 21 to handheld portion 23 in proper order, its scale mark reduces from a left side to the right side in proper order promptly, make 1 outer wall scale mark of cylinder and the 2 body of rod 22 of piston spare correspond mutually of scale mark, avoid medical personnel's sight can receive the medicine colour, the piston position, the restriction of operation finger and patient's health, be convenient for medical personnel to use the observation of medicine in-process to remaining dose at the patient, medical personnel's error when the injection has been reduced.
Furthermore, the outer wall of the needle cylinder 1 is provided with a light shielding device, and the light shielding device comprises a light shielding piece 4 and a connecting column 5 arranged on the outer wall of the left end of the needle cylinder 1. The shading part 4 is a folding rubber cylinder, the right end of the shading part is fixed with the outer wall of the right end of the needle cylinder 1 through fixing parts such as viscose, a connecting hole is formed in the left end of the shading part, the shading part 4 can be connected with the left end of the needle cylinder 1 by sleeving the connecting hole on the outer wall of the connecting column 5, and the shading part 4 covers the outer wall of the needle cylinder 1. Specifically speaking, in the stage of dispensing or when need not be to the shading of syringe 1 inner wall medicine, the left end that is equipped with the connecting hole with light-shading piece 4 does not cup joint with spliced pole 5 on the syringe 1, and the scale of syringe 1 outer wall is exposed so, and because light-shading piece 4 initial state is folding, its axial length is short, and also be equipped with the scale on the piston post, just so can not influence the observation of medical personnel to syringe 1 outer wall scale in the process of using medicine. When needing to hide the light to the inside medicine of syringe 1, medical personnel's application of force is in the 4 left ends of light-shading spare, flare-outs it to cup joint the connecting hole of light-shading spare 4 on spliced pole 5 of syringe 1, light-shading spare 4 covers syringe 1 inside promptly, thereby realizes the shading of the inside medicine of syringe 1. It should be noted that, the length of the needle cylinder 1 is greater than the axial length of the light-shielding member 4 when the light-shielding member 4 is not folded, so that when the light-shielding member 4 is fixed on the plate of the connecting column 5 of the needle cylinder 1, the rubber cylinder is in a tight state, and the light-shielding member 4 cannot fall off from the connecting column 5 of the annular plate of the needle cylinder 1 without external force, thereby avoiding the defect that the light cannot be shielded because the light cannot fall off in the middle of the rubber cylinder.
Parts not described in the above modes can be realized by adopting or referring to the prior art.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
