Process and device for introducing a physiological fluid at a prescribed temperature in human and animal organisms. The fluid is pumped through a regulated heating means (59) into a gravity-feed container (95), then led by natural gravity out of the gravity-feed container (95) through the same heating means (59) into the organism. While the fluid is being pumped into the gravity-feed container (95, the temperature of the fluid entering the heating means (59) is measured and on the basis of the temperature measured the heating means (59) is set to a temperature or a corresponding heat flow which produces essentially the prescribed temperature of the fluid leaving the heating means (59). While the fluid is being led by natural gravity, the temperature of the heating means (59) is regulated until the prescribed temperature of the fluid is obtained. A heating means (59) suitable for this device comprises at least two heating lateral walls (28, 128) and a channel (47) passing between them. Each side wall (28, 128) has a heating resistance net and a temperature sensor. The resistance network is composed of a heating foil pattern (2, 102) formed on the side of an electrically isolating base plate (1, 101) facing the medium to be heated. On the other side of the base plate (1, 101) is formed a sensor foil pattern (3, 101) forming a temperature sensing resistance and covered with an isolating layer (15, 115).

A method for introducing a physiological fluid into a human or animal organism at a prescribed temperature, wherein the fluid is pumped through a controlled heating device into a gravity tank and then introduced from the gravity tank through the same heating device into the organism by gravity, characterized in that during the pumping into the gravity tank the temperature of the fluid entering the heating device is measured and, on the basis of the measured temperature, a temperature or a heat flux causing substantially the prescribed temperature of the fluid discharging from the heating device is set in the heating device, and that during the introduction by gravity the temperature of the heating device is controlled to the prescribed temperature of the fluid.
