Treatment unit for intensive care of premature babies has an arrangement of heaters with a temperature controller circuits and a coupling circuit between the two controllers to ensure correct overall temperature

摘要

Heater arrangement for an intensive care unit has two temperature controller circuits for two heaters together with a coupling circuit that controls the temperature of the second heater as a function of the temperature of the first heater. First heater (5) has a temperature control circuit (9) to set the temperature around the patient (2). A second heater (3) in the support surface (4) has a second temperature control circuit (12). A coupling circuit (15) is arranged between first and second control circuits and has the actual temperature or nominal temperature of the first controller as an input. Via a temperature coupling function (17) the coupling circuit adjusts the temperature setting for the second heater dependent on the value of the first heater.
