Moreover, one end of the outer jacket layer 10 is provided with an outlet corresponding to the output end of the infusion bag 100, so that the output end of the infusion bag 100 extends out of the outer jacket layer 10 conveniently for infusion of a patient.

The air bag 20 expands and contracts and increases and decreases air pressure in the inner cavity of the outer sheath layer 10 through the inflation or the deflation of air. For the convenience of inflation and deflation, the air bag 20 is provided with an air inlet valve 21 and an air outlet valve 22, and the air inlet valve 21 is connected with an air pump to inflate the air bag 20. When the air bag 20 needs to be decompressed, the air is exhausted by opening the exhaust valve 22.

In this embodiment, as shown in fig. 2, the airbag 20 is wrapped around the infusion bag 100, and the heating unit 30 is disposed between the airbag 20 and the infusion bag 100.

Further, in the present embodiment, the heating unit 30 includes a heat conducting plate 31, and a heat generating member 32 disposed on the heat conducting plate 31. The heating element 32 is located on the surface of the heat conducting plate 31 facing the airbag 20, and the heating element 32 is externally connected with a power supply through wires which extend out of the outer jacket layer 10. After the power is supplied, the heating member 32 heats and transfers heat to the heat conducting plate 31, and the heat is transferred to the infusion bag 100 through the heat conducting plate 31 to heat the infusion bag to a predetermined temperature (e.g. consistent with or close to the body temperature of a person).

The heating element 32 may be a plurality of heating rods or a heating wire. The heat conducting plate 31 is preferably a plate having good heat conductivity and insulation.

In other embodiments, the air bag 20 is located on one side of the bag 100 and the heating unit 30 is located on the opposite side of the bag 100, as well as providing a heating and pressurizing effect on the bag 100.
