The device needs to be used in conjunction with a motor and is inconvenient to carry.

[0027] Embodiment 1

[0028] like Figures 1 to 4 As shown, the utility model provides a clinical pharmaceutical dispensing device, comprising: a mounting base 1; a mixing medicine box 2 connected to the mounting base 1 for storing medicines; a dispensing component 3 for mixing medicines is arranged in the mixing medicine box 2; the dispensing component 3 comprises a nut 301 connected to the top of the mixing medicine box 2, a threaded rod 302 is threadedly connected to the nut 301, one end of the threaded rod 302 extends into the mixing medicine box 2 and is connected to a plurality of stirring blades 303, the plurality of stirring blades 303 are arranged in parallel up and down, and the other end of the threaded rod 302 is rotatably connected to a force application plate 304.

[0029] When medicines that need to be mixed and prepared are stored in the medicine mixing box 2, the force plate 304 can be pressed downward to drive the threaded rod 302 to move downward. During the downward movement, the threaded rod 302 can be affected by the nut 301 and can move downward while rotating. At this time, the stirring blade 303 can be affected by the rotation of the threaded rod 302 to stir and mix the medicine liquid. When the force plate 304 is pressed to a certain position, the force plate 304 can be moved upward again to make the threaded rod 302 drive the stirring blade 303 to rotate and stir in the opposite direction. This setting facilitates multi-directional stirring of the medicine liquid, and the stirring range is adjustable, which further improves the stirring efficiency and stirring effect.

[0030] For details, please refer to Figure 2 A plurality of guide holes 5 are provided on the stirring blade 303, and the plurality of guide holes 5 are evenly spaced and distributed in a linear array. This arrangement can increase the contact area between the liquid and the medicine solution, making the mixing more uniform.

[0031] For details, please refer to Figure 1 and Figure 2A feed pipe 6 is connected to the top of the mounting base 1, and the shape of the feed pipe 6 is set to be funnel-shaped. The feed pipe 6 is set to be convenient for adding liquid medicine into the mixing medicine box 2, and the funnel shape is set to be convenient for pouring the liquid medicine and collecting the liquid medicine into the mixing medicine box 2.

[0032] For details, please refer to Figure 2 and Figure 4 A compression spring 4 is sleeved on the threaded rod 302, one end of the compression spring 4 is connected to the nut 301, and the other end is connected to the force plate 304. This arrangement is convenient for providing an upward force to the force plate 304, so that the force plate 304 can drive the threaded rod 302 to move upward, saving the energy of medical staff during operation.

[0033] Embodiment 2

[0034] On the basis of the first embodiment, a buffer assembly 7 for buffering the pressing force is further provided in the mounting base 1, and the buffer assembly 7 includes a mounting base 701 connected to the bottom of the medicine mixing box 2, and a transmission plate 702 is rotatably connected to the mounting base 701, and the other end of the transmission plate 702 is rotatably connected to a connecting base 703, and the connecting base 703 is slidably connected to the inner bottom wall of the mounting base 1, and a damper 704 is connected to one side of the connecting base 703, and the other end of the damper 704 is connected to the inner side wall of the mounting base 1, and a buffer spring 705 is sleeved on the damper 704, and one end of the buffer spring 705 is connected to the damper 704, and the other end is connected to the inner side wall of the mounting base 1.

[0035] In the process of pressing the force plate 304, a downward force will be generated on the mixing medicine box 2. As the use time increases, the downward force is continuously applied to the mixing medicine box 2, which is likely to cause certain damage to the mixing medicine box 2. For this reason, the buffer component 7 is designed to buffer this force. When the mixing medicine box 2 moves downward, the mounting seat 701 moves downward. At this time, the transmission plate 702 can drive the connecting seat 703 to move toward the direction of the inner wall of the mounting base 1, and then the damper 704 and the buffer spring 705 can be used together for buffering. This setting can effectively extend the service life of the mixing medicine box 2.

[0036] Specifically, there are two groups of buffer components 7, and the two groups of buffer components 7 are symmetrically connected to the bottom of the mixed medicine box 2. A sliding groove for the connecting seat 703 to slide is opened in the mounting base 1. It is set in two groups to improve the stability of the buffering of the mixed medicine box 2. The set sliding groove limits and guides the moving direction of the connecting seat 703, thereby improving the stability of the movement of the connecting seat 703.

[0037] Working principle: When medicines that need to be mixed and prepared are stored in the medicine mixing box 2, the force plate 304 can be pressed downward to drive the threaded rod 302 to move downward, and the threaded rod 302 can be affected by the nut 301 to move downward while rotating during the downward movement, and the stirring blade 303 can be affected by the rotation of the threaded rod 302 to stir and mix the medicine liquid, and when the force plate 304 is pressed to reach a certain position, the force plate 304 can be moved upward again to make the threaded rod 302 drive the stirring blade 303 to rotate and stir in the opposite direction, which is convenient for stirring the medicine liquid in multiple directions, and the stirring range can be adjusted, further improving the stirring efficiency and stirring effect;

[0038] When the medicine mixing box 2 moves downward, the mounting seat 701 moves downward. At this time, the transmission plate 702 can drive the connecting seat 703 to move toward the inner wall of the mounting base 1. Then the damper 704 and the buffer spring 705 can be used together for buffering. This setting can effectively extend the service life of the medicine mixing box 2.

[0039] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
