Constant-temperature pressurized infusion device

The utility model relates to a constant-temperature pressurized infusion device, which comprises a rear air storage sac, a middle heating bag and a front liquid bag fixing membrane. The lower part of the air storage sac is connected with an inflation ball with an air valve through a tracheae. A carbon fiber heating wire electrically connected with an external temperature controller through a power line is arranged in the heating bag. The liquid bag fixing membrane is horizontally arranged in front of the heating bag. The air storage sac is provided with a liquid suspension hook used for hanging a liquid bag. According to the technical scheme of the utility model, the constant-temperature pressurized infusion device is simple in structure, and safe and convenient to operate. When the liquid bag is put into the front liquid bag fixing membrane and externally connected with a power supply, the liquid in the liquid bag can be heated in real time. When the pressurized infusion is required, the air is driven to enter the air storage sac through the tracheae through extruding the inflation ball. The air storage sac is inflated to expand in size. In this way, the liquid in an infusion bag is extruded to be quickly infused into the human body of a patient. The infusion speed can be adjusted automatically according to the pressure valve in the air storage sac through the inflating and pressurizing process.
