Monitoring system for elderly person includes activity sensor and physiological sensor combined to initiate warning of fall

摘要

The system for detection of a possible fall by a person includes a device for detecting activity, or lack of activity, of the person. The significance of this information is confirmed by a further detector sensing a physiological parameter, such as pulse, arterial pressure, breathing rate or temperature. When both of these sources of information indicate abnormal conditions, an alarm signal is generated. The system for detection of a possible fall by a person includes a device for detecting a potentially abnormal situation. This may be provided by one, or preferably two accelerometers providing a signal indicating the activity, or lack of activity, of the person. The significance of this information is confirmed by a further detector sensing a physiological parameter, such as pulse, arterial pressure, breathing rate or temperature. When both of these sources of information indicate abnormal conditions, an alarm signal is generated and this is transmitted to a remote position in order to call for assistance.
