Chair-Check System

The Chair-Check System is a wandering patient system designed to prevent individuals with Alzheimer's Disease, cognitive disabilities, or balance disabilities from leaving a wheelchair or other chair without assistance. The system includes a portable Chair-Check II control unit and disposable SENSORMAT sensor. This unit, which can also be used for bed monitoring in a home setting, sets itself automatically when weight is detected on the SENSORMAT and provides an immediate alarm when the individual's weight is removed from the sensor. An immediate alarm is required for a chair becaue when weight is removed, the individual is in the posture to stand. A user-selectable three-second delay is available when the system is used for bed monitoring. Selectable alarm tones enables the alarm to be distinguished from those of other equipment and an alternate tone may be chosen for a prioity alert when the individual being monitored is at high risk. POWER: Uses a standard nine-volt alkaline battery or an optional rechargeable nickel-metal hydride battery. The optional battery includes a battery charger which permits up to 1,000 battery charges. The control unit continuously monitors battery condition while the unit is set for use and provides an audible low battery alert.
