[ 22. A method for inhibiting microbial growth in a human body temperature control system used during extracorporeal circulation, wherein temperature control is achieved by use of a circulating temperature control liquid, the method comprising:
connecting a single-use heat exchanger to a circuit of temperature control liquid connected to a temperature control device including a disinfectant sensor, wherein the temperature control liquid is provided from and returned to an open air reservoir;
circulating the temperature control liquid through the heat exchanger and the temperature control device, each of the heat exchanger and the temperature control liquid disposed at separate locations, wherein the temperature control liquid includes a disinfectant to inhibit microbial growth in the temperature control system;
generating a disinfection status of the disinfectant from a concentration of disinfectant measured by the sensor to be one of sufficiently disinfected, minor contamination, and change temperature control liquid;
circulating blood from the human body through the heat exchanger, such that the blood enters the heat exchanger through a blood inlet disposed substantially perpendicular to a flow of the temperature control liquid; and
disconnecting and disposing the heat exchanger.]
