CARDIORESPIRATION AUXILIARY DEVICE USING ARTIFICIAL RESPIRATORY APPARATUS AS BLOOD PUMP DRIVING SOURCE SIMULTANEOUSLY AS OXYGEN-ADDED MIXED GAS SUPPLY SOURCE

摘要

PROBLEM TO BE SOLVED: To provide an external circulating type cardiorespiration auxiliary device to be applied to cure a patient fallen into the cardiorespiratory malfunction in which an artificial respiratory apparatus is used as the blood pump driving source simultaneously as the oxygen added mixed gas supply source. ;SOLUTION: An artificial respiratory apparatus 2 is connected to a blood pump driving part, for instance, to bellows or the like incorporated with a spring constituting both a membrane-type artificial lung 7 and a blood pump, and an inflow one-way valve 5 and an outflow one-way valve 6 are fitted, and the blood pump driving part, for instance, bellows or the like incorporated with the spring is driven by using the driving force of artificial respiratory apparatus supply mixed gas 1, so that the artificial respiratory apparatus in which the blood in a blood pump cardiac ventricle part 8 is driven out as outflow blood 3 through the membrane-type artificial lung 7 and an outflow blood vessel 11, or the inflow blood enters the blood pump cardiac ventricle part 8 through an inflow blood vessel 10 and the membrane-type artificial lung 7 is used as the blood pump driving source simultaneously as the oxygen added mixed gas supply source.;COPYRIGHT: (C)1999,JPO
