Portable, multi-channel, physiological data monitoring system
First Claim
1. An apparatus for notifying an ambulatory caregiver of the physical condition of a patient, comprisingmonitoring means positionable on the patient and responsive to the physical condition of the patient for determining whether the ambulatory caregiver should be notified and for transmitting a caregiver notification signal when it is determined that the ambulatory caregiver should be notified;
- base station means positionable apart from the patient and responsive to the transmitted caregiver notification signal for relaying the transmitted caregiver notification signal over a plurality of redundant but independent transmission paths; and
receiver means positioned apart from the base station means and positionable on the ambulatory caregiver and responsive to the transmitted caregiver notification signal as relayed by the base station means over each of the plurality of redundant but independent transmission paths for providing a predetermined indication to the ambulatory caregiver that a Caregiver notification signal has been received.

Abstract
The system of the present invention provides a link between the caregiver and the subject being monitored which utilizes an intermediate base station and redundant signal paths between the base station and the caregiver. The caregiver wears a unit which receives signals from the base station. Signals from the base station provide information about the subject being monitored and provide signals for use in determining whether the caregiver remains within the range of the base station. The unit worn by the subject being monitored can include diagnostic circuitry for evaluating signals received from sensors to transmit an alarm signal to the base station when the subject being monitored is in need of assistance. A range monitoring system is provided which will alert the subject being monitored as well as the caregiver whenever the subject being monitored moves outside the range of the base station.

7. An apparatus for notifying an ambulatory caregiver of the physical condition of a patient, comprising
monitoring means positionable on the patient for obtaining and transmitting physiological data from the patient; -
base station means positioned apart from the patient and responsive to the physiological data transmitted by the monitoring means, including means for determining whether the ambulatory caregiver should be notified and for transmitting a caregiver notification signal over a plurality of redundant but independent transmission paths when it is determined that the caregiver notification signal should be given; and receiver means positioned apart from the base station means and positionable on the ambulatory caregiver and responsive to the caregiver notification signal as transmitted by the base station means over each of the independent transmission paths for providing a predetermined indication to the ambulatory caregiver that a caregiver notification has been received.
