When a patient needs infusion, it is often necessary to mix a variety of different drugs according to the condition to prepare a therapeutic solution with better efficacy. In clinics, medical staff can transfer drugs from different containers, such as medicine bottles, into infusion bags for mixing to obtain the therapeutic solution required by the patient.

[0044] The implementation principle of a fresh air device for a dispensing machine in this embodiment is as follows:

[0045] Reference Figure 7The fresh air device is arranged above the dispensing machine. The openings on the bottom of the upper frame 1 are respectively connected to the storage area, the liquid dispensing area and the internal space of the dispensing machine. The first exhaust pipe 2112 is connected to the bottom of the storage area, and the second exhaust pipe 2232 is connected to the bottom of the liquid dispensing area. When the fresh air device is running, the filter fan 5 inside the upper frame 1 is driven to supply air to each functional area inside the dispensing machine through the openings on the bottom of the upper frame 1. The air inside the upper frame 1 is filtered and purified by the filter fan 5 and then transported to the inside of the dispensing machine. During the operation of the filter fan 5, the first air cavity 21 The first exhaust pipe 2112 and the first exhaust port 2111 connected to 1 respectively extract the air inside the dispensing machine and the storage area into the first air cavity 211, and the air is transported to the second cavity 12 through the first air cavity 211, and is purified by the filter fan 5 inside the second cavity 12 before being transported to the dispensing machine and the storage area. Similarly, the air inside the dispensing area is extracted to the fifth air cavity 223 through the second exhaust pipe 2232, and is transported to the first cavity 11 through the fifth air cavity 223, and is filtered by the filter fan 5 before being transported to the dispensing machine and the liquid dispensing area. Thus, air circulation inside the dispensing machine is realized. During the operation of the fresh air device, 70% of the air in the dispensing machine is repeatedly filtered to realize circulation, and 30% of the air enters the fresh air device through the air inlet component 3. During operation, the operator pushes the baffle 33 to move along the guide rail 34 to open the air inlet 31. The outside air is filtered by the filter layer 32 and enters the upper frame 1. It is then filtered by the filter fan 5 and then transported to the dispensing machine. The operator controls the air intake of the air inlet 31 by controlling the position of the baffle 33 to meet the needs in different situations. A waste storage area is provided in the dispensing machine. The waste storage area is connected to the fourth air outlet 2221. An air purification device is provided at the fourth air outlet 2221. During the air circulation inside the dispensing machine, 30% of the air from the waste storage area enters the fourth air outlet 2221 after being purified by the air purification device, and then is discharged through the exhaust pipe 4, thereby purifying the polluted air in the waste storage area and discharging it, thereby realizing the air circulation inside the dispensing machine, ensuring the stable wind speed and wind pressure inside the dispensing machine, and ensuring the stability of the internal environment of the dispensing machine.

[0046] In summary, in this application, a vertical frame and an upper frame are provided, a filter fan is provided inside the upper frame, and an air cavity connected to the dispensing machine is provided inside the vertical frame. The air in the dispensing machine is pumped to the upper frame through the vertical frame, filtered by the filter fan, and then transported to the dispensing machine, thereby realizing the circulation filtration of the air in the dispensing machine, ensuring the sterile environment inside the dispensing machine, improving the stability of the wind speed and wind pressure inside the dispensing machine, and reducing the use cost of the dispensing machine; in this application, multiple independent cavities and wind cavities are provided inside the upper frame and the vertical frame, and the multiple independent cavities and wind cavities are respectively connected to different functional areas in the dispensing machine, realizing independent air supply to different functional areas, and ensuring the stability of the wind speed and wind pressure inside the dispensing machine.
