Latest Patents

One of his latest inventions is an advanced oxygenator designed to inhibit or prevent bubbles in blood from exiting through a blood outlet. This oxygenator features a part that performs gas exchange on blood and a heat exchanging part for temperature regulation. The design includes a housing in a rectangular parallelepiped form, containing a hollow fiber membrane bundle. This bundle is composed of multiple hollow fiber membranes that facilitate gas exchange. Blood flows through gaps between these membranes, allowing for effective gas exchange with the gas flowing through the lumens of the fibers. Additionally, a filter member is strategically placed downstream to capture any bubbles present in the blood.

Another innovative oxygenator developed by Ogihara helps avoid the discharge of bubbles through the blood outlet port. This device includes a housing, a hollow fiber membrane bundle, and both gas-inlet and gas-outlet ports. A filter member is positioned closer to the blood outlet port to catch bubbles, while a passage enlargement near the outlet allows for deceleration of blood flow, ensuring that filtered blood reaches the outlet smoothly.
