Before the infusion bag is pressurized, the pressurized airbag 10 is in a depressurized state, which is convenient for putting the infusion bag between the pressurized airbag 10 and the fixing member 20; The bag bears the pressure of the pressurized air bag 10, and will quickly flow out to the patient for infusion during infusion.

In some embodiments, a pressure sensing device 12 is provided on the pressurized surface 11 to sense the pressure between the pressurized airbag 10 and the infusion bag. The pressure sensing device 12 includes a pressure sensor, or a displacement sensor protruding outwards for abutting against the infusion bag. Before the infusion, the liquid medicine in the infusion bag is more, and the pressure of the pressurized air bag 10 will be large. During the infusion, as the liquid medicine in the infusion bag decreases, the pressure between the pressurized air bag 10 and the infusion bag will will also decrease.

Further, the infusion pressurizing device also includes an alarm device (not shown) electrically connected to the pressure sensing device 12, and the alarm device may include a buzzer or a warning light. When the pressure sensed by the pressure sensing device 12 is small to a certain extent, the alarm device starts to remind the medical staff to pull out the needle or replace the infusion bag in time.
