Abstract

This artificial lung includes: a housing; a hollow fiber membrane layer that is housed inside the housing and in which a multitude of hollow fiber membranes having a gas exchange function are integrated; a gas inflow section and a gas outflow section that employ the lumen of each hollow fiber membrane as a gas flow path and that are provided respectively on the upstream side and the downstream side of the gas flow paths; a blood inflow section and a blood outflow section that employ the outside of the hollow fiber membranes as a blood flow path and that are provided respectively on the upstream side and the downstream side of the blood flow path; a first filter member that is provided in contact with the surface of the hollow fiber membrane layer on the side of the blood outflow section and covers almost the entire surface, the first filter member having the function of capturing bubbles in the blood; and a second filter member spaced away from the first filter member and arranged between the first filter member and the blood outflow section, the second filter member having the function of capturing bubbles in the blood.

Description

technical field

[0001] The present invention relates to artificial lung (oxygenator) and extracorporeal circulation device. Background technique

[0002] At present, as an extracorporeal circulation device used in cardiac surgery, the following extracorporeal circulation device is known: a bubble trap, a centrifugal pump, and an artificial lung are arranged sequentially from the upstream side of the flow path of the blood circulation, and they are connected to each other. Connect with a tube (for example, refer to Patent Document 1). In the extracorporeal circulation apparatus described in the aforementioned Patent Document 1, the air bubble removing device is a device for removing air bubbles from blood taken from a patient. In addition, a centrifugal pump is a blood pump that circulates blood so as to take blood from a patient and return the taken blood to the patient again. The artificial lung is a device having a hollow fiber membrane layer in which a plurality of holl...
