[0027] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the drawings required for the implementation are briefly introduced below. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0029] Combination Figure 1-Figure 5 As shown, the utility model provides a handheld medicine dispensing machine, comprising a medicine dispensing machine handle 1 and a syringe 2 connected to the medicine dispensing machine handle 1 .

[0030] According to one embodiment of the utility model, the handle 1 of the dispensing machine includes a housing 11, and the housing 11 includes an upper housing 111 and a lower housing 112 that match each other. A push rod 3 and a driving device 4 are installed in the lower housing 112. In this embodiment, the driving device 4 includes a driving motor 41 and a threaded rod 42 connected to the driving motor 41. A control button is provided on the upper housing 111 for controlling the start and stop of the driving motor 41 and the rotation direction of the driving motor 41. The push rod 3 is provided with a threaded hole that matches the threaded rod 42. The driving motor 41 works and drives the threaded rod 42 to rotate. Since the rotation direction of the push rod 3 is limited by the housing 1, when the threaded rod 42 rotates, the push rod 3 moves along the threaded rod 42.

[0031] According to one embodiment of the present invention, the front end of the lower housing 112 is connected to a connecting portion 5, and the syringe 2 is connected to the connecting portion 5. According to the concept of the present invention, the connecting portion 5 and the lower housing 112 can be an integrally formed structure, and the connecting portion 5 can also be set as a separate structural member, which is detachably fixedly connected to the lower housing 112.

[0032] Specifically, in this embodiment, the connecting portion 5 includes a main body portion 51 and an extended support portion 52 connected to the main body portion 51 . The main body portion 51 is provided with a mounting groove 511 , and the flange portion of the syringe 2 is mounted in the mounting groove 511 to achieve positioning of the syringe 2 .

[0033] The front end of the push rod 3 of the utility model is provided with a second connecting portion 6, the connecting portion 5 is located outside the second connecting portion 6, the second connecting portion 6 is connected with a piston member 7, and the second connecting portion 6 is provided with a second mounting groove 61. In this embodiment, the piston member 7 includes a syringe connecting portion 71, a transition portion 72 and a circular plate portion 73 connected in sequence. Among them, the syringe connecting portion 71 is installed with a sealing rubber, the syringe connecting portion 71 extends into the syringe 2 and seals with the syringe 2, and the circular plate portion 73 cooperates with the second mounting groove 61 to realize the connection between the piston member 7 and the push rod 3, and when the push rod 3 moves, the piston member 7 moves.

[0034] The handheld dispensing machine of the present invention can well position and fix the syringe 2 through the cooperation between the syringe 2 and the mounting groove 511 , and the cooperation between the circular plate portion 73 and the second mounting groove 61 , which helps to ensure that there will be no leakage during the dispensing process.

[0035] In the handheld dispensing machine of the present invention, the transition section 72 is also connected to a baffle 74. This arrangement can prevent the piston 7 from entering the deep of the syringe 2 during transportation, making it impossible to remove the piston 7. The connection between the transition section 72 and the baffle 74 is easily broken, and the baffle 74 can be broken off when it is needed to be installed and used.

[0036] The handheld matching machine of the utility model has the following working principle:

[0037] The piston member 7 and the syringe 2 are connected to the dispenser handle 1 in the above manner, and the drive motor 41 is controlled by the control button on the upper housing 111 to drive the screw 42 to rotate, thereby realizing the movement of the push rod 3, that is, controlling the movement of the piston member 7 in the syringe 2 to realize the dispensing operation. The control method of the drive motor 41 and the screw 42 is conducive to realizing accurate dispensing.

[0038] Combination Figure 6 and Figure 7 As shown, the handheld dispensing machine of the utility model also includes a disinfection box 8, a disinfection area 81 is provided inside the disinfection box 8, and an opening and closing cover 82 is provided in the disinfection box 8. When in use, the handle 1 of the dispensing machine of the utility model can be placed in the disinfection area 81, disinfected and sterilized by ultraviolet rays, and then covered with the opening and closing cover 82 for disinfection.

[0039] The above is only one embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
