The pump body driving module can be used for receiving a control instruction of the control device and driving the pump to operate according to the control instruction. The pump body drive module may include circuitry or components known to those skilled in the art for driving operation of the pump body. Taking the first input pump 11 as an example, the first pump body drive module 111 may be electrically connected or in communication with the control device 30 (specifically the first control module 31). The control device 30 can send corresponding control signals (e.g. flow control signals, start/stop signals) to the first pump body driving module 111 according to the set control parameters to control the first pump body 112 to perform the desired operation.

In the embodiment of the present application, the control device 30 may further include a user input module 35, and the user may input dispensing information (for example, a dispensing ratio or a dispensing amount) through the user input module 35.

In an embodiment of the present application, the control module for the liquid preparation input unit may include a timer. As shown in fig. 2, the first control module 31, the second control module 32, and the third control module 33 may respectively include a first timer 311, a second timer 321, and a third timer 331.

Since the flow rate of each pump body may be preset (i.e., the pump flow rate per unit time is determined), the control module may calculate the amount of the input medical fluid based on the flow rate and the operation time of the pump body. For example, the first control module 31 may calculate the amount of the liquid medicine (the liquid medicine in the first medicine storage container 61) pumped by the first pump body 112 to the liquid medicine mixing mechanism 20 according to the preset flow rate of the first pump body 112 and the timing of the operation time of the first pump body 11 by the first timer 311. In addition, after the user inputs the dispensing information for the first pump body 112 through the user input module 35, the first control module 31 may calculate the operation time required by the first pump body 112 according to the preset flow rate and the dispensing information of the first pump body 112. When the first control module 31 controls the first pump driving module 111 to drive the first pump 112 to start, the first timer 311 may be started to start timing, and when the timing of the first timer 311 reaches a required operation time, the first control module 31 may control the first pump driving module 111 to drive the first pump 112 to close, so that the liquid medicine input of the required dosage is completed.

Fig. 4 is a cross-sectional axial view of fig. 3. Referring to fig. 3 and 4, in the present embodiment, the liquid medicine mixing mechanism 20 may take the form of a stirring cylinder 201. In order to achieve sufficient stirring, the liquid medicine mixing mechanism 20 may further include a stirring motor and a rotary stirring member disposed in the hollow cylinder chamber, the stirring motor being disposed in the hollow top case chamber B and connected to drive the rotary stirring member. That is, the chemical liquid mixing mechanism 20 adopts a motor drive system. In another embodiment of the present application, in consideration of the fluid impact force of the pumped fluid, in the embodiment shown in fig. 3 and 4, the stirring motor may be omitted, and the fluid impact force is directly used to drive the rotary stirring member to work. Therefore, the chemical liquid mixing mechanism 20 may include a rotary stirring member disposed in the hollow cylindrical cavity, and the liquid inlet fluid of the stirring liquid inlet 205 may impact and rotate the rotary stirring member.

And the design of the end part plug is beneficial to the disassembly, assembly and maintenance of the liquid medicine mixing mechanism.

More importantly, the stirring liquid inlet 205 can be arranged on the wall of the stirring cylinder 201 in a penetrating manner, and the impact force of liquid inlet fluid brought by the stirring liquid inlet 205 can impact the rotary vane 204 to rotate, so that the whole rotary shaft 203 is driven to rotate, and the full stirring and mixing of multiple kinds of medicines in the liquid medicine mixing cavity D are completed. The dynamic action of the fluid is effectively utilized, so that the stirring motor and the like are saved correspondingly, the cost is reduced, and the same full stirring effect on the liquid medicine can be realized. Therefore, the entire chemical mixing mechanism 20 according to the embodiment of the present invention has a simple and practical structure, high chemical mixing efficiency, and low manufacturing cost.

When applied to a dispensing device, the cylinder wall of the mixing cylinder 201 may be provided with a plurality of mixing liquid inlets 205 arranged at intervals along the axial direction to adapt to a plurality of dispensing liquid inlet flow paths. After entering the liquid medicine mixing chamber D, the multiple paths of fluids are uniformly mixed under the stirring of the rotary stirring member and output from the stirring liquid outlet 206 at the end.

In the embodiment of the present application, after the control device 30 (e.g., the first control module 31, the second control module 32, and the third control module 33) inputs the required liquid medicine and water into the liquid medicine mixing mechanism 20 for mixing and stirring, the fourth control module 34 may control the fourth pump driving module 141 to drive the fourth pump 142 to operate, so as to pump the mixed liquid medicine to the liquid storage container 200. In one example, the fourth control module 34 may control the fourth pump driving module 141 to drive the fourth pump 142 to operate after a predetermined time after all of the required medical fluids are input into the medical fluid mixing mechanism 20. The predetermined time may be set to a time required for the liquid medicine mixing mechanism 20 to sufficiently stir and mix the input liquid medicine and water or a time longer than this time.

Referring to fig. 2 and 5, in the present embodiment, the dispensing device may further include a priming gun 40, and the liquid medicine output unit may communicate with the liquid storage container 200 through the priming gun 40. The drenching gun 40 may be detachably communicated with the liquid medicine output unit, and may be electrically connected or communicated with the control device 30 when communicated with the liquid medicine output unit. Specifically, the outlet of the fourth pump body 142 of the output pump 14 may be in communication with the reservoir 200 via the fill gun 40. As shown in fig. 5, the medicine filling gun 40 may be provided with a retaining member 44, the retaining member 44 may be pivotally connected to a side wall of an outlet end of the medicine filling gun 40, and an elastic member may be disposed between the retaining member 44 and the side wall of the medicine filling gun 40, wherein an end of the elastic member abutting against the retaining member 44 is in contact with a side wall of the outlet end of the medicine filling gun 40. In use, the end of the catch 44 remote from the outlet of the gun 40 is depressed.

In the embodiment of the present application, the filling gun 40 may further include a fourth detection module 41, where the fourth detection module 41 is configured to detect a state of the liquid medicine filled in the liquid storage container 200, that is, whether the liquid medicine is filled or not, or how much liquid medicine is filled or a liquid level of the liquid medicine in the liquid storage container 200. As shown in FIG. 5, the fourth detection module 41 may include two conductive bars 411, and when the liquid medicine filled in the liquid storage container 200 contacts the two conductive bars 411 to cause a short circuit, a signal indicating the amount of liquid medicine filled or filled in the liquid storage container 200 or the liquid level of the liquid storage container 200 may be generated (depending on the particular application for which the fourth detection module 41 is provided).

The drenching gun 40 may further include a fourth information acquisition module 42 for acquiring information of the state detected by the fourth detection module 41.
