Title:
RISING MOTION DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2009005964
Kind Code:
A
Abstract:

To detect rising motion of a person lying on a bed with high precision.

The rising motion detection device is provided with sensors 2a-2c to detect whether or not an obstacle exists in space above the bed 1. The sensors 2a-2c are installed on the head side or the foot side of the bed 1. A sensor detection line 5a of the sensor 2a is parallel to the mat upper surface of the bed 1 to be parallel to the body axis of the person 6 lying on the bed 1. Sensor detection lines 5b and 5c of the sensors 2b and 2c approach the first sensor detection line as they advances from the sensor installation side toward the center of the bed 1 in the body axis direction of the person 6 lying on the bed 1. The sensors 2a-2c are installed at a position higher than the highest position of the body as the person 6 lies on the bed 1, and lower than the highest part of the head when the person 6 lies down long on the bed 1. A detection means 3 detects rising motion of the person on the bed 1 based on state change of detection results by the sensors 2a-2c about whether or not there is an obstacle.
