A recently granted patent (Publication Number: US11883641B2) discloses a blood pump designed to efficiently pump blood through a channel using an axial flow impeller. The pump includes a housing with an inner wall surface defining an inlet, an outlet, and a blood flow channel. An axial flow impeller made of magnetic material is positioned within the channel and is rotated by a motor stator generating a magnetic field. The design ensures that the impeller is stabilized in the axial direction by hydrodynamic forces and magnetic fields, preventing it from moving upstream.
Furthermore, the blood pump described in the patent does not include permanent magnets but utilizes a system of first and second permanent magnets to stabilize the impeller in the axial direction. The pump also features additional components such as conical bearings and yokes to enhance stability and increase magnetic flux density. The method of operating the blood pump involves utilizing the motor stator to suspend and rotate the impeller, with the magnetic field urging the impeller towards the inner wall surface to maintain stability. Overall, the patented blood pump design aims to provide efficient and stable blood flow through the channel, ensuring optimal performance and reliability in medical applications.
