Abstract
Abstract The invention relates to a medical parameter monitoring device which allows the monitoring of a plurality of medical parameters from a remote location. The invention uses a central monitoring system which transmits and receives data parameters via RF from remote patient monitors. The monitoring system utilizes a digital spread spectrum RF transceiver between the central monitoring system to the remote monitors. Forward error correcting, frequency hopping, and spread spectrum communications are employed to provide accurate transmission of data for a plurality of physiological parameters. Transmitted data can be automatically registered into storage in the central monitoring system.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
181 words
A method for monitoring a plurality of physiological parameters of a patient, comprising the steps of: providing at least first and second central monitoring systems for monitoring a plurality of physiological parameters, the central monitoring systems each including a first transceiver; coupling a patient monitor having a second transceiver to said patient to monitor at least one said physiological parameter; continually transmitting a first data signal corresponding to said physiological parameters from said patient monitor to said first central monitoring system, the first data signal including a patient location signal; transmitting a second data signal from said first central monitoring system to said patient monitor to remotely select at least one of the plurality of physiological parameters to monitor; displaying a continuous representation of at least one physiological parameter on a display coupled to the first central monitoring system; automatically switching control from the first central monitoring system to the second central monitoring system based on the patient location signal; and displaying a continuous representation of at least one physiological parameter on a display coupled to the second central monitoring system.
Claim 2
Independent Claim
181 words
A method for monitoring a plurality of physiological parameters of a patient, comprising the steps of: providing at least first and second central monitoring systems for monitoring a plurality of physiological parameters, the central monitoring systems each including a first transceiver; coupling a patient monitor having a second transceiver to said patient to monitor at least one said physiological parameter; continually transmitting a first data signal corresponding to said physiological parameters from said patient monitor to said first central monitoring system, the first data signal including a patient location signal; transmitting a second data signal from said first central monitoring system to said patient monitor to remotely select at least one of the plurality of physiological parameters to monitor; displaying a continuous representation of at least one physiological parameter on a display coupled to the first central monitoring system; automatically switching control from the first central monitoring system to the second central monitoring system based on the patient location signal; and displaying a continuous representation of at least one physiological parameter on a display coupled to the second central monitoring system.
Claim 3
Dependent Claim
50 words
The method as defined in claim 1, further including the step of switching monitoring control from the first central monitoring system to the patient monitor when the patient is in transit, and automatically switching the control to the second central monitoring system when the patient reaches a new stationary location.
Claim 4
Dependent Claim
37 words
The method as defined in claim 1, further including the step of automatically recognizing said patient monitor has established bidirectional communications with the central monitoring system and automatically displaying information based upon said monitoring on said display.
