Abstract

Disclosed is a device which helps caregivers of demented patients, such as persons suffering from Alzheimer'"'"'s disease, monitor and safeguard the wellbeing of the patients. The device, which is attached to the wrist or the leg of the patients, monitors the movement and behavior of the patient and informs the caregivers whenever unexpected or alarming incidences occur. The device may identify if the patient has fallen, wondered off or is inactive for long periods of time. The device records and learns the patterns of daily behavior of the patient in relation to which it may identify unexpected occurrences. The device is equipped with sensors which enable it to monitor the location, behavior and condition of the patient. Additionally, the device may be programmed to identify particular behaviors as alarming. Selectively activating its sensors and communication interface, the device is especially equipped to operate on low battery consumption.

Claims
