Abstract: A radiation imaging device according to one embodiment comprises a radiation detection panel, a base substrate having a support surface configured to support the radiation detection panel, and a housing, wherein: the housing has a top wall and a bottom wall, the base substrate has a protruding portion which protrudes further outward than the radiation detection panel when seen in a direction orthogonal to the support surface, a first extending portion is provided to the support surface of the protruding portion, a second extending portion is provided to a back surface of the protruding portion, the second extending portion being disposed at a position which it faces the first extending portion with the protruding portion interposed therebetween, and the base substrate is supported on the top wall via the first extending portion and is supported on the bottom wall via the second extending portion.

Abstract: A procedure simulator is provided, which includes a first storage tank configured to store a liquid imitating blood; a tissue model including a plurality of bifurcated flow paths being bifurcated downstream via a plurality of bifurcated portions; a pump configured to supply the liquid to the tissue model; a second storage tank configured to store the liquid to be flowed out from the plurality of bifurcated flow paths; a plurality of pipes configured to connect an outlet of a bifurcated flow path to the second storage tank; a plurality of switching valves configured to selectively causing the bifurcated flow path to communicate with a drain flow path from which the liquid is discharged below the tissue model; and a filter member between the switching valve and the outlet of the bifurcated flow path of the plurality of bifurcated flow paths.

Abstract: A technique simulator for training in a technique using a catheter includes: a flow path configured to contain a liquid that imitates blood; a liquid flow generation member configured to generate flow of the liquid; and a catheter insertion port configured to allow the catheter to be interposed into the flow path. The flow path includes: a bifurcated portion that is located downstream of the catheter insertion port and is to be bifurcated into at least two flow paths, and a plurality of bifurcated flow paths provided downstream of the bifurcated portion. The plurality of bifurcated flow paths includes a first bifurcated flow path and a second bifurcated flow path. The technique simulator further comprises a pressure difference generation member configured to cause a pressure difference to be generated between a downstream side of the first bifurcated flow path and a downstream side of the second bifurcated flow path.

Abstract: A highly safe catheter assembly exhibiting excellent torque transmission, pushability and kink resistance and operation of a guidewire is provided. The catheter assembly comprises a catheter having a lumen extending between an opening on its distal end and an opening in its periphery in distal end portion of the catheter for insertion of a guidewire therethrough, and a covering sheath for covering said catheter together with the guidewire, said covering sheath having a guidewire passage means for enabling passage of said guidewire from its interior to its exterior. The catheter of this assembly may be a PTCA catheter.
