Title:
SEAT-LEAVING MONITORING DEVICE FOR WHEELCHAIR
Document Type and Number:
Japanese Patent JP2015023888
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a seat-leaving monitoring device for a wheelchair using an electrostatic capacitance type mat sensor as a seat-leaving sensor that can reduce power consumption of a battery power source as much as possible.SOLUTION: A seat-leaving monitoring device for a wheelchair includes: an electrostatic capacitance type mat sensor 30 arranged on a seating surface of a wheelchair; a battery power source 44 for supplying power to the mat sensor 30; switch means SW1 connected between the mat sensor 30 and the battery power source 44; and a care-giver absence detection means for detecting an absence time when a care-giver who attends on a care-receiver leaves the wheelchair by a prescribed distance or more. When the care-giver is present within the prescribed distance from the wheelchair, the care-giver absence detection means turns the switch means SW1 off, and stops power supply from the battery power source 44 to the mat sensor 30, bringing the mat sensor 30 into a non-detection state, and when the care-giver is absent away from the wheelchair by the prescribed distance or more, the care-giver absence detection means turns the switch means SW1 on, and supplies power to the mat sensor 30 from the battery power source 44, bringing the mat sensor 30 into a detection state.
