Abstract
A chair having a monitoring device disposed on the back support of the chair for detecting a change in position of a patient. The monitoring device indicates when the patient is no longer in contact with the device to provide a warning when the patient is falling forward, or is slouching in the seat. The monitoring device may be a single sensor or multiple sensors. The monitoring device may be permanently affixed to the chair, or integrated into the back of the chair. The monitoring device may be adjustable in position, or it may be moveable from the back of the chair. Multiple monitoring devices may be provided, or a single monitoring device having multiple zones may be provided or detection or more complex behavior. Typically, an output is provided to a controller which may or may not activate a warning system. The warning system may be visual, such as a light, or it may be audible, such as a siren or the like. The warning system may be either adjacent to or remote from the patient. A counter may be used to enable a time delay before a warning is sounded to avoid false alarms. A method is also provided for detecting movement of a patient in a chair utilizing a monitoring device disposed on the back support of the chair.
