摘要： Provided is a centrifugal blood pump capable of preventing a blood clot from forming. A centrifugal blood pump 1 is provided with a housing 10, an impeller 20 disposed inside the housing 10, and a magnetic drive part 30. The impeller 20 comprises a base 23, a top shroud 24 having a blood introduction opening 241, a plurality of guide parts 26, a rotation axis member 21 having a lower end 211 axially supported by a lower surface part 13 of the housing 10 and rotatable about a rotation axis J, and a first magnetic body 27 disposed below the base 23. The magnetic drive part 30 comprises a second magnetic body 312, and drives the impeller 20 rotationally about the rotation axis J with the first magnetic body 27 and the second magnetic body 312 being magnetically coupled due to a magnetic coupling force acting to cause the first magnetic body 27 and the second magnetic body 312 to attract each other in the vertical direction. A top surface 242 of the top shroud 24 and a lower surface 121 of an upper surface part 12 of a blood container 11 are formed to narrow from the radially outer side toward the radially inner side of the top shroud 24.

摘要： A tube distal end position detection system (1) includes a light source device (50) that emits light, a hollow tube (10) having a flow path (11) that allows a liquid to flow through, a connector (20) provided at a base end of the tube so as to allow light from the light source device to be incident on an end surface (12) at the base end of the tube, and a light emitting portion (30) provided at the distal end of the tube. Light from the light source device passes through the tube and is emitted from the light emitting portion and transmitted to the body surface.

摘要： Provided is a stent which can ensure storability in thin tubular members such as delivery systems and which is insusceptible to positional displacement after placement of the stent in an affected part of a bodily conduit. This synthetic resin 1 comprises a tubular first braid component 2 comprising a plurality of fibers that are braided into a net-like form, and a second braid component 3 comprising a plurality of fibers that are disposed braided into the first braid component 2 to form an annular shape. The first braid component 2 includes a plurality of first fibers 21, a plurality of second fibers 22, and a plurality of first intersections 23, and the second braid component 3 includes a plurality of wave-like third fibers 31 disposed separated in an axial direction and a plurality of wave-like fourth fibers 32 disposed separated in the axial direction. At least one of the first intersections 23 is disposed in an intersection region 34 surrounded by the third fiber 31 and the fourth fiber 32.

摘要： A first member (10) and a second member (20) are coupled to each other in a coupling portion (100). The first member includes, on the opposite side to the coupling portion, a main portion (51) that is connectable to a counterpart connector. The main portion and the second member are in communication with each other via a flow channel (102). One of the first member and the second member includes an outer cylindrical portion (30), and the other of the first member and the second member includes an inner cylindrical portion (40). In the coupling portion, the inner cylindrical portion is fitted in the outer cylindrical portion. The outer cylindrical portion includes a first engagement portion (31) and an abutment portion (35). The inner cylindrical portion includes a second engagement portion (41) that engages the first engagement portion, and a leading end (45) that is a front end of the inner cylindrical portion in a direction in which the inner cylindrical portion is fitted into the outer cylindrical portion. As a result of the first engagement portion and the second engagement portion engaging each other, the leading end of the inner cylindrical portion abuts against the abutment portion of the outer cylindrical portion along a central axis (101).
