Artificial Lung Device

Abstract: An artificial lung device comprising: a tubular housing (3002) including both ends that are closed; a heat exchanger (3061) provided in the housing and configured to perform heat exchange with respect to blood; a gas exchanger (3045) arranged around an axial direction of the heat exchanger in the housing and configured to be in fluid communication with the heat exchanger and perform gas exchange with respect to the blood; a heat medium partial chamber (3035) which is arranged between the heat exchanger and the gas exchanger and around the axial direction of the heat exchanger and through which a heat medium flowing in and out from the heat exchanger flows; a blood inflow port (3016) provided at a first end side of the housing and configured to be in fluid communication with the heat exchanger; a blood outflow port (3017) provided at the housing and configured to be in fluid communication with the gas exchanger; a medium inflow port (3020) and a medium outflow port (3021) which are provided at a second end side of the housing and are in fluid communication with the heat medium partial chamber; and a bridge structure (3070) forming a blood passage (3044) through which the blood flows in a radial direction from the heat exchanger through a second end side of the heat medium partial chamber to the gas exchanger and a medium passage (3071, 3072) through which the heat medium flows in the axial direction between the medium inflow port and the heat medium partial chamber and between the medium outflow port and the heat medium partial chamber.
