Abstract
There is provided an apparatus which reduces a bleeding amount upon an operation. A bloodless treating apparatus used upon a surgical treatment of an objet comprises: (A) a fluid replacement supply unit which quantitatively supplies a fluid replacement into a blood vessel leading to the object (24); and (B) a fluid replacement withdrawing unit which quantitatively withdraws the fluid replacement having passed through the object (24) from a blood vessel coming from the object.
Claims9
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- (2) the measured withdrawn fluid replacement temperature;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- a withdrawn fluid replacement temperature sensor which measures a temperature of the withdrawn fluid replacement;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- (C) a blood supply unit which recovers blood contained in the withdrawn fluid replacement, and controls a temperature of the recovered blood, which is supplied into a third blood vessel.
A method for reducing a bleeding amount upon a surgical treatment of an object, which method comprises the steps of:
- (A) quantitatively supplying a fluid replacement of which temperature has been adjusted into a blood vessel by means of a fluid replacement supply unit;
- (B) controlling a temperature of the fluid replacement which is quantitatively supplied by the fluid replacement supply unit 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- (2) the measured withdrawn fluid replacement temperature;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;
- (C) quantitatively withdrawing the fluid replacement from a blood vessel;
- (D) measuring a temperature of the withdrawn fluid replacement by means of a fluid replacement withdrawing unit;
- (E) recovering blood contained in the withdrawn fluid replacement;
- and
- (F) returning the blood into the object via a blood vessel preferably after controlling a temperature of the recovered blood.
