    Abstract: 기계식 접촉베어링을 대신해 로터리펌프용 "무접촉" 베어링 메커니즘이 구현되었다. 여러가지 로터와 하우징 디자인이 자기식이나 유체식 베어링에 구현되었다. 이들 디자인의 특징들은 서로 결합되기도 한다. 기계식 접촉베어링이 부족하면 펌프수명이 늘어나고 혈액과 같은 작동유체의 파손이 줄어든다. 본 발명의 펌프는 펌핑실(112)을 구성하면서, 펌핑실 안으로 뻗는 스핀들(130)을 갖는 펌프하우징(110)을 포함한다. 스핀들 자석조립체(160)의 스핀들 내부에는 제1, 제2 자석(262,264)이 서로 반대되는 자기벡터로 서로 근접되게 스핀들 내부에 배열되어 있다.

    Abstract: An impeller (22) has a rotating shaft (7) supported by an upper bearing (9) and a lower bearing (10) to rotate freely at the upper and lower ends, a plurality of vanes (6), an arm (18) for coupling the inner circumferential side of a vane with the rotating shaft, an annular coupling portion (8) coupled to the outer circumferential side of each vane, and a driven magnet portion (12) arranged below the annular coupling portion. A drive magnet portion (16) provided on a rotor (13) and the driven magnet portion (12) oppose each other while holding the bottom wall of the housing between them, and rotation of the rotor is transmitted to the impeller through magnetic coupling. A blockade member (23) is arranged below the vane and the space of a region spread between the rotating shaft and the annular coupling portion is blocked while an opening (24) is left at least around the rotating shaft. In a structure where the rotating shaft of the impeller is supported by upper and lower bearings and the lower portion at the outer circumferential edge part of the vane is coupled by the annular coupling portion, formation of a blood clot in the vicinity of the lower bearing can be suppressed.

    Abstract: An axial-flow blood pump for pumping blood includes a substantially cylindrical outer enclosure. A tubular housing concentric with and located within the outer enclosure has at one end an inlet and at an opposite end an outlet. A motor stator is concentric with and located between the outer enclosure and the tubular housing. An impeller is concentric with and located within the tubular housing. The impeller is suspended in operation by a combination of passive magnetic forces between magnets within the impeller or magnetized regions of the impeller and the motor stator and hydrodynamic thrust forces generated as blood flows between the tubular housing and a plurality of hydrodynamic thrust bearing surfaces located on the impeller. A volute may be in fluid-tight connection with the outlet of the tubular housing for receiving blood in the axial direction and directing blood in a direction normal to the axial direction. The volute has a flow-improving member extending axially from the volute and into and coaxially with the tubular housing.

    Abstract: A novel in vivo perfusion method for inducing differential signaling in an animal is provided to obtain direct changed conditions of target proteins according to presence or restraint of signal transmission. A novel in vivo perfusion method for inducing differential signaling in an animal includes the steps of: cutting an abdomen of an animal and obtaining an organ, an artery and a vein to be perfused; inserting and fixing a blood catheter into the vein; connecting the catheter with a perfusion tube; circulating a solution that is used in a control group in the tube; separating a piece of organ as a control group after finishing perfusion using the solution; and removing the organ of the control group, moving the perfusion tube to a solution including a group of compounds of a test group, and performing perfusion.
