  • Publication number: 20150157778
    Abstract: A magnetic driving pump device includes: an impeller; driven bodies integrally rotating together with the impeller and including permanent magnets; a drive unit including a magnet body on which a permanent magnet is placed such that when the drive unit rotates around a predetermined axis, different magnetic poles alternately appear on an outer periphery of the drive unit; and a rotation actuator rotating the magnet body around its axis. The magnet body is arranged side-by-side with respect to the driven bodies in a state that an axis of the magnet body is oriented to a direction which is not at right angles with respect to a rotation center of the impeller, and the impeller is rotated through the driven bodies by rotating the magnet body by the rotation actuator.

  • Patent number: 7697970
    Abstract: In a capsule 3 as a medical apparatus inserted into a body cavity, the lengthwise direction of the capsule 3 is used as an insert axis, a manipulation/input device 8, which is magnetized in a direction orthogonal to the insert axis, is disposed at the center position of the insert axis. A magnetic field generation device 4, which is disposed outside of a body, is caused to generate a vibration magnetic field in a direction parallel with the insert axis of the capsule 3 by turning on a vibration (ON/OFF) switch 8f of a manipulation/input device 8 so that couples having lines of action, which are in parallel with the insert axis, are exerted on the capsule 3, thereby the capsule 3 executes a swiveling motion about the insert axis and smoothly travels along a cavity organ.

  • Publication number: 20100030026
    Abstract: A medical apparatus main body such as a capsule main body inserted in the body cavity includes a thrust generating mechanism such as a spiral projection. The medical apparatus main body further forms an information providing unit comprising at least one of a storing unit for storing a state of the thrust generating mechanism and a direction detecting unit for detecting the direction of the medical apparatus main body. An input unit instructs a thrust generating direction of the thrust generating mechanism and thus a control unit changes continuously or the like a thrust generating state of the thrust generating mechanism based on information from the information providing unit.
