Patent ID: 6855122

Claim:
A bloodless treating apparatus used for a surgical treatment of an object, comprising: (A) a fluid replacement supply unit which quantitatively supplies a fluid replacement into a first blood vessel leading to the object, comprising: a supplied fluid replacement temperature sensor which measures a temperature of the supplied fluid replacement; and a means for controlling a temperature of the fluid replacement to be supplied based on a different extent between: (1) an averaged temperature of the measured supplied fluid replacement temperature; (2) the measured withdrawn fluid replacement temperature; and (3) the predetermined temperature of the object; (B) a fluid replacement withdrawing unit which quantitatively withdraws the fluid replacement from a second blood vessel coming from the object, after the fluid replacement passed through the object, comprising: a withdrawn fluid replacement temperature sensor which measures a temperature of the withdrawn fluid replacement; and (C) a blood supply unit which recovers blood contained in the withdrawn fluid replacement, and controls a temperature of the recovered blood, which is supplied into a third blood vessel.
