Blood transfusion bag heating device

In order to meet clinical requirements, guarantee blood transfusion quality and control blood bag heating speed, hot air circulation heating is adopted. A blood transfusion bag heating device comprises a box body, a box cover, a transverse partition plate, a longitudinal partition plate, a fan, an air supply pipe, an air return pipe, a control panel, a heater and a swing device. The box body is divided into a heating chamber, a temperature rising chamber and a power chamber through the longitudinal partition plate and the transverse partition plate. A temperature rise curve is calculated according to the set heating time; in the heating process, a controller compares the actual temperature rise curve with the calculated temperature rise curve, the temperature of hot air is controlled by adjusting the output power of the heater and the rotating speed of the fan, damage caused by the temperature difference to blood is reduced, and meanwhile the actual temperature rise curve and the calculated temperature rise c
