First Claim
Patent Images
1. A patient location system for locating a patient within a plurality of bounded spaces comprising:
- stationary location marker means fixed with respect to a bounded space for generating a location code;
patient identification means affixed to a patient for generating a patient identification signal;
low power link for communicating the location code from the stationary location marker means to the patient identification means only when the patient identification means is in the bounded space;
a physiological monitor means for monitoring a physiological signal from the patient;
first transmitter means affixed to the patient and communicating with the patient identification means and the physiological monitor means for transmitting the location code, the patient identification signal, and the physiological signal when the stationary location marker means is in communication with the patient identification means through the low power link; and
stationary receiver means for receiving the location code and patient identification signal whereby the patient identification means may be associated with the location means.

Abstract
A miniature multi-lead bio-telemetry and patient location systems includes one or more stationary location markers which transmit location data to an ECG unit worn by ambulatory patients. The electrocardiogram (ECG) unit monitors patient ECG data, a distress button and ECG unit status and combines this data with the location data received from one location marker and retransmits this combined data to a stationary receiver which may display the ECG data the system status data and the location data.

5. A bio-telemetry and patient location system for monitoring physiological signals of a patient within a bounded space which comprises:
-
stationary location marker means for transmitting a presettable location code on a low power communication link, wherein said stationary location marker is fixed within a bounded space and the power level within the bounded space is above a signal threshold; mobile receiver means attached to the patient for receiving said location code signal only if it is above the signal threshold and including a physiological monitor means for monitoring a physiological signal from the patient; transmitter means communicating with the mobile receiver means for combining the location code signal received by the mobile receiver means with the physiological signal and transmitting the combined physiological signals and location code signal; and stationary receiver means for receiving the transmitted combined physiological signals and location code. - View Dependent Claims (6, 7, 8, 9)
