Patent ID: 11480483

Abstract:
A load detector for detecting a load of a subject on a bed (BD) having a caster (CT) includes: a plate portion (1) which is one-fold and which is to be supported above an installation surface (F), on which the load detector is installed, separately from the installation surface; and a slope portion (SL1, SL2, SL3, SL4) which is provided around the plate portion and which is inclined relative to a surface of the plate portion so as to extend between the surface of the plate portion and the installation surface. The plate portion includes: a peripheral part (13); a placing part (11) on which the caster is to be placed, and which is provided inside relative to the peripheral part separately from the peripheral part; and a linking part (12) which links the placing part and the peripheral part. The load detector further includes a strain sensor (G) attached to the linking part, and the slope portion includes at least two pairs of slopes (SL1, SL2, SL3, SL4) each including a pair of slopes opposed to each other such that the placing part is interposed between the pair of slopes.
