With a total of 3 patents to his name, Anai's work focuses on enhancing the efficiency and safety of blood circulation devices.

Latest Patents

Anai's latest innovations include two distinct turbo blood pump designs. The first patent describes a turbo blood pump that is compact in size, allowing for a minimal amount of blood to be filled while maintaining a consistent flow. This design minimizes the risk of hemolysis, even when operating at high rotational speeds necessary for optimal discharge capabilities. The pump features a housing with an inlet and outlet port, and an impeller that rotates within the housing. The impeller is designed with a rotation shaft and an annular connection portion, to which multiple vanes are attached. Notably, the vanes are positioned at a skew angle to enhance performance.

The second patent outlines a turbo blood pump that includes a pump chamber, an inlet port, and an outlet port. This design incorporates an impeller supported by upper and lower bearings, which allows for smooth rotation. The upper bearing is strategically placed below the inlet port, ensuring that the cross-sectional area of the pump chamber is larger than that of the inlet port. This configuration reduces the likelihood of blood stagnation and thrombus formation, making the pump safer for medical use.
