[0026] The working principle of the present application is as follows: The first infusion bag 12 is filled with dissolving solution, which can dissolve the powdered medicine in the vial 33. The second infusion bag 13 is used as a raw liquid collecting bag, which is initially empty. After the dissolving solution is completely mixed with the powdered medicine, the first pump body 14 is used to pump the completely dissolved medicine back into the second infusion bag 13. In order to avoid the mixing of the initial dissolving solution and the medicine, the infusion channel connected to the first infusion bag 12 and the infusion channel connected to the second infusion bag 13 are independently arranged. The bottom of the infusion bag is provided with a hole, which is convenient for the hook 11 to pass through the hole for fixation. The infusion bag is made of light-shielding material, which can avoid the direct sunlight on the medicine in the infusion bag for a long time, so as to prevent the temperature from rising and the activity from decreasing. The first pump body 14 and the second pump body 23 can provide power for the delivery of the medicine, which can deliver the medicine from a low place to a high place. This not only facilitates the placement of the preparation equipment, but also saves the use space.
[0027] The first infusion channel 3 is a channel specially used for delivering dissolving solution. The dissolving solution in the first infusion bag 12 first passes through the switching valve 5 through the independent first branch pipe 31, and then enters the first pump body 14 along the infusion main road 15. The driving of the first pump body 14 makes the dissolving solution pass through the puncture device 32 and be delivered into the vial 33. Since the first infusion bag 12 is located at the highest point, the dissolving solution can also flow into the vial 33 under the action of gravity without the need of power provided by the first pump body 14. Therefore, in the process of delivering the dissolving solution, the first pump body 14 is used to accelerate the falling speed of the dissolving solution, so as to improve the efficiency of medicine preparation. The second infusion channel 4 is a channel specially used for delivering the medicine prepared initially. After the dissolving solution is fully mixed with the medicine in the vial 33, the prepared medicine needs to be first driven by the switching valve 5 through the driving block 5201 to block the first branch pipe 31. Under the action of the first pump body 14, the prepared medicine in the vial 33 is pumped out and enters the second branch pipe 41 along the infusion main road 15, and finally is pumped into the second infusion bag 13. When the second infusion bag 13 is filled, the infusion switch 3204 on the puncture device 32 needs to be closed to avoid the reflow of the medicine into the vial 33 in the subsequent medicine preparation process.
[0028] Through the first infusion channel 3 and the second infusion channel 4, the dissolution, collection and preparation of dangerous medicine can be completed. Through the third infusion channel 6, the buffer solution can be sub-packed, which reduces the contact between people and dangerous medicine and greatly improves the safety of the medicine preparation process.
[0029] At the same time, the lifting seat 9 can make the buffer solution input into each sub-packaging bag 95 consistent. After the buffer solution is infused, the switching valve 7 is automatically opened to switch the infusion channel, the raw liquid is input into the sub-packaging bag 95 to complete the preparation of the medicine, and the sub-packaging bag 95 is sealed after the preparation is completed, which ensures the accuracy of the medicine preparation and greatly improves the efficiency of the liquid preparation.
