[0003] Chinese Utility Model Patent CN 217853869 U discloses a general-purpose electric medicine preparation device. Among them, the fixing structure and transmission structure of the syringe of this device adopt a structure with upper and lower staggering. At the same time, the battery pack and the main control board are arranged below the transmission structure. The disadvantages of this device are that the large number of components leads to a relatively complex structure, and at the same time, the poor structural layout results in a large volume. However, its advantage is that it can be generally adapted to conventional syringes. In addition, Chinese Utility Model Patent CN 218853113U discloses an electric medicine preparation device. The fixing structure and transmission structure of the syringe of this device adopt a front-back linear structure. At the same time, the battery pack and the main control board are also arranged below the transmission structure. Although the structural composition and layout of this device have changed compared with the above structure, it requires a special syringe (that is, a structure with a hollow accommodation cavity in the syringe piston rod) for supporting use, and it cannot be generally applicable to conventional syringes. In addition, the above two structures are not conducive to single-handed holding operation, and it is sometimes easy to slip and is laborious when piercing into the infusion bottle.

[0004] The inventor of the present invention at least found the following problems during the implementation of this embodiment:

Therefore, based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0032] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0033] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] This embodiment provides a handheld electric medicine dispenser. Please refer to Figures 1-4 as shown, which includes a housing 100, an electric lead screw 200, an electric control component 300, and a piston slide 400. The housing 100 has a fixing part 110 for fixing the syringe outer shell. The electric lead screw 200 is installed in the housing 100 and includes a connected motor 210 and a lead screw 220. The electric control component 300 is sleeved on the lead screw 220. The piston slide 400 is slidably connected in the housing 100 and is in transmission connection with the electric lead screw 200 for driving the syringe piston rod to move bidirectionally.

[0035] Specifically, the housing 100 is designed in a linear tubular shape for convenient single-handed holding operation, avoiding the problem of inconvenient single-handed holding operation when the housing 100 is too thick or wide. Among them, the piston slide 400 can be slidably connected in the housing 100 through a concave-convex fitting structure. Among them, the electric lead screw 200 can be directly connected to the piston slide 400. At this time, a special syringe needs to be used. In addition, it can also be in transmission connection with the piston slide 400 through the following wire tube 500. At this time, conventional syringes can be generally used. Among them, the wire tube 500 can be fixedly connected to the piston slide 400 through fasteners such as screws. At the same time, the wire tube 500 and the piston slide 400 can be rotationally limited through the concave-convex fitting structure between the peripheral walls, so as to avoid relative rotation between the two.

[0036] Furthermore, the lower part of the housing 100 is provided with a concave-convex anti-slip holding part 120.

[0037] Specifically, the shape of the holding part 120 is adapted to the fingers, increasing the comfort and anti-slip property of the holding, and the operation is relatively labor-saving.

[0038] Furthermore, the upper part of the housing 100 is provided with a protruding installation groove part 130 for installing a control button 140 and can be used as an anti-slip pressing part.

[0039] Specifically, the circumferential groove wall of the installation groove portion 130 protrudes. The groove wall near the tail can be used as a non-slip pressing portion for the thumb to press to increase friction, facilitating the insertion of the syringe needle into the infusion bottle. At the same time, the control key 140 can be embedded in the installation groove portion 130, making it convenient to operate directly after insertion. Among them, the control key 140 can include forward, switch, and backward, and is arranged on the upper part for visual and accurate operation control.

[0040] Further, the electric control component 300 includes a battery 310 and a main control board 320; the battery 310 is installed on the main control board 320 and is electrically connected thereto. The main control board 320 is provided with a through hole 330 for passing through the lead screw 220.

[0041] Specifically, the battery 310 and the main control board 320 adopt an integrated assembly design, which reduces the volume compared with the layered and independent setting and is convenient for assembly. At the same time, the through hole 330 is used to pass through and accommodate the lead screw 220 and the wire tube 500, providing a structural basis for generally adapting to the syringe.

[0042] Further, the battery 310 is multi-section, and it is arranged around the main control board 320 and around the through hole 330.

[0043] Specifically, the middle part of the circuit board has holes and is spaced, which is equivalent to forming a battery holder with an axial hole. At the same time, the battery 310 is installed around the battery holder, that is, between the circuit boards, and around the middle hole. In this way, the internal space of the housing 100 can be fully utilized, maintaining the compact and portable volume, and at the same time facilitating single-handed operation.

[0044] Further, it further includes a wire tube 500. The wire tube 500 is threadedly connected to the lead screw 220, and is fixedly connected to the piston slider 400 and can move through the through hole 330.

[0045] Specifically, the function of the wire tube 500 here is similar to that of a nut, and it moves in cooperation with the piston slider 400 to realize the bidirectional movement of the syringe piston rod.

[0046] Further, a limit hole plate 150 is provided in the housing 100, and the wire tube 500 slides through the limit hole plate 150.

[0047] Specifically, on the one hand, the limit hole plate 150 can limit the end of the electric control component 300, and on the other hand, it also plays a certain role in limiting the sliding of the wire tube 500 to prevent it from shaking.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
