Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 The temperature-controlled liquid preparation system shown includes a preparation tank 1 and an electrical box 2. The preparation tank 1 has a cavity 11 with an open top and a tray 12 installed at the bottom. A liquid bag 13 containing the preparation solution can be placed inside the cavity 11. The liquid bag 13 is inserted from the top of the cavity 11 and then placed on the tray 12. A lid 14 is sealed on the top of the cavity 11 and closed after the liquid bag 13 is inserted, forming a closed space within the cavity 11. This creates a closed refrigeration environment and reduces [temperature / damage]. Energy consumption: When using the liquid medicine, the lid 14 can be opened to retrieve the liquid medicine bag 13. A refrigerant channel 15 is formed on the side wall of the dispensing tank 1, surrounding the cavity 11.

The electrical box 2 is connected to the dispensing tank 1. The electrical box 2 contains a refrigerator 21 and an exhaust gas treatment device 22. The refrigerant channel 15 is connected to the refrigerant 21 via piping. The refrigerator 21, often referred to as a refrigeration compressor, can create a cooling effect on the circulating refrigerant. Figure 2As shown, the liquid preparation tank 1 side wall is connected with the flange seat 16, the liquid preparation tank 1 is fixedly connected with the electrical box 2 through the flange seat 16, the flange seat 16 is connected, so that the liquid preparation tank 1 and the electrical box 2 can be conveniently disassembled and assembled, when the liquid preparation tank 1 and the electrical box 2 are disassembled, the pipe connection between the refrigerant channel 15 and the refrigerator 21 is installed from the inside of the flange seat 16, so that after the liquid preparation tank 1 and the electrical box 2 are connected, the connecting pipeline is covered by the flange seat 16, and is not exposed to the workshop environment, even if there is a liquid leakage, it is also in the flange seat 16, and does not affect and pollute the sterile environment of the workshop, the refrigerator 21 generates waste gas during use, and the direct exhaust of the waste gas will pollute the sterile environment of the workshop, therefore, the utility model installs the waste gas treatment device 22 in the electrical box 2, the waste gas treatment device 22 is connected with the exhaust pipe of the refrigerator 21, so that the exhaust gas of the refrigerator 21 is treated by the waste gas treatment device 22, and clean air is discharged, and the sterile environment of the workshop is not affected and polluted, the top of the electrical box 2 is provided with a control console 3, the control console 3 is provided with a liquid crystal screen, and the opening and closing of each electrical equipment can be conveniently controlled, and the electrical box 2 is provided with a mobile power supply 23, and the mobile power supply 23 can supply power to all electrical equipment, the utility model can realize self-power supply, so that the power connection position in the workshop is not needed, and the pollution risk is further reduced, and the refrigeration and storage structure is reasonably integrated, so that the refrigeration use demand in the sterile workshop is met.

[0024] As shown in the figure, Figure 2 The tray 12 is provided with a weight sensor 121, the weight sensor 121 transmits data to the control console 3, and the liquid bag 13 is placed on the tray 12 to form a weight display, so that the pharmaceutical worker can master the storage amount of the liquid medicine in real time.

[0025] The refrigeration needs to maintain a suitable temperature, therefore, as shown in the figure, Figure 2 The box cover 14 is provided with a temperature sensor 141, the temperature sensor 141 can detect the temperature of the cavity 11 after the box cover 14 is closed, and the measured data of the temperature sensor 141 is transmitted to the control console 3 in real time, so that the pharmaceutical worker can understand and adjust in time.

[0026] The configuration liquid medicine also has the demand of maintaining uniformity, therefore, as shown in the figure, Figure 2 The utility model installs a magnetic motor 122 on the tray 12, the magnetic motor 122 can generate magnetic force change, the liquid bag 13 is preinstalled with a stirring impeller 131 which can be driven by magnetic force, the stirring impeller 131 is driven to rotate by the magnetic motor 122, so that the liquid medicine in the bag is always in a stirring motion state, and the uniformity is good, the magnetic motor 122 and the liquid bag 13 with the magnetic force driven stirring impeller 131 are all finished products which can be purchased on the market, and the specific structure is not introduced here.

[0027] Magnetic stirring must be performed while the refrigerator is refrigerated. To ensure that workers do not misoperate, such as... Figure 2 As shown, this utility model has a magnetic control element 17 installed in the liquid preparation tank 1. The magnetic control element 17 and the magnetic motor 122 form a circuit control, such as... Figure 3 As shown, an opening slot 18 is provided on the side wall of the liquid preparation tank 1. The top of the opening slot 18 is open, and a magnetic switch 181 is installed at the bottom of the opening slot 18. The magnetic switch 181 is connected to the magnetic motor 122. The magnetic control element 17 includes an elastic box 171, a trigger rod 172, and a spring 174. The elastic box 171 is fixedly installed in the opening slot 18. The trigger rod 172 is vertically installed through the elastic box 171. A guide piston 173 is fixedly connected to the outer wall of the trigger rod 172. The guide piston 173 is matched and installed in the elastic box 171. The guide piston 173 plays a guiding role in the movement of the trigger rod 172, so that the trigger rod 172 can only move up and down. The spring 174 is sleeved on the outside of the trigger rod 172. One end of the spring 174 is connected to the guide piston 173, and the other end is connected to the bottom of the inner hole of the elastic box 171. The guide piston 173 also plays a role in pressing the spring 174. The function of the lid 14 is to be pushed upward by the elastic force of the spring 174. In this invention, a counterweight 142 is installed on the top of the lid 14 to increase the overall weight of the lid 14. During the closing process, the lid 14 can press down the trigger rod 172 by its own weight. At this time, the guide piston 173 will compress the spring 174. After the trigger rod 172 moves downward, it can press the magnetic switch 181. Only when the magnetic switch 181 is pressed can the magnetic motor 122 be controlled and started. The advantage of this design is that if the lid 14 is not installed, the magnetic motor 122 will not be started by accident (if the lid 14 is not installed, the top of the trigger rod 172 is not under force, and the trigger rod 172 is pushed up under the elastic force of the spring 174, and the trigger rod 172 does not contact the magnetic switch 181). The installation of the lid 14 generally indicates that the refrigerated space has been formed, and at this time, the magnetic motor 122 needs to be started.
