RESPIRATION MONITORING DEVICE, BODY MOVEMENT DETECTION BELT, BODY MOVEMENT DETECTION SYSTEM, AND RADIATION DELIVERY SYSTEM
The present invention is provided with: a belt (710) which is attached to the periphery of the body and, due to the at least partial inclusion of a stretchable member, can be stretched in the longitudinal direction as a whole
non-metal wires which are arranged along the longitudinal direction on at least a portion of the stretchable member, the length that is arranged on the stretchable member being varied by the stretching of the stretchable member
a tubular member (750) for guiding a portion extending from the portion of the stretchable member of a first non-metal wire to a position separated from the belt, by passing through the interior
a detection unit (760) for detecting movement of the non-metal wires at the separated position
an urging member for keeping a constant tension of the non-metal wires between the detection unit and the belt
and a respiration status output unit (760) for outputting the respiration status detected by the detection unit.
