[0021] Figure 1 This is a schematic diagram of syringe dispensing. When the syringe is used to prepare powder injection drugs, the solvent is first sucked out from the mother liquid bag with a syringe, and then the solvent in the syringe is injected into the powder injection bottle. After the drug is dissolved in the solvent, the dissolved liquid medicine is sucked out with a syringe. After the suction is completed, the liquid medicine needs to be injected into the mother liquid bag to finally complete the transfer and dispensing of the powder injection medicine. When the water injection drug is prepared, the solute (drug) is first sucked out from the water injection with a syringe, and then the solute in the syringe is injected into the mother liquid bag to finally complete the transfer and dispensing of the water injection medicine. The above two drug preparation processes require repeated suction operations using syringes, which is time-consuming, labor-intensive, and inefficient. When dispensing large quantities of drugs, the labor intensity is high and it is easy to cause personal injury to the operator.

[0022] Figure 2 This is a schematic diagram of a sterile cover with a motorized booster device (patent number: 201320442585.3). The motorized booster device of this device is completely isolated in the isolation chamber of this sterile cover. When the motorized booster device is turned on, it can push the sealed piston to move toward the injection chamber and then push the syringe to complete sterile automatic injection. Sterilization before use or single-use can avoid contamination of the outer surface of the shell to the operating table and the operator. It is suitable for uniform and slow injection of small amounts of liquid in the sterile environment of a micro-plastic surgery table. It is disposable, but the motor and screw of the device are connected in series at the back of the syringe, making the entire device too long, with slow thrust, short standby time, and uncomfortable holding.
