BODY-WORN VITAL SIGN MONITOR
First Claim
1. A system for monitoring vital signs from a group of patients, comprising:
- (a) a monitoring device worn on the body of each patient in the group, each monitoring device comprising;
a wireless system;
a first sensor configured to generate a first time-dependent waveform indicative of one or more contractile properties of the patient'"'"'s heart;
a second sensor configured to generate a second time-dependent waveform indicative of one or more contractile properties of the patient'"'"'s heart; and
a processing component configured to;
(i) receive a first signal representing the first time-dependent waveform;
(ii) receive a second signal representing the second time-dependent waveform;
(iii) calculate a blood pressure value from a pulse transit time measured between the first and second signals or versions thereof; and
(iv) transmit the blood pressure value with the wireless system; and
(b) a remote display device in communication with each monitoring device through the wireless system comprised by the monitoring device, the remote display configured to simultaneously display a blood pressure value for each patient in the group when a signal strength corresponding to the wireless system comprised by each monitoring device is below a pre-determined threshold value, and further configured to display a blood pressure value for a particular patient when the signal strength from the wireless system worn by the patient exceeds the pre-determine threshold.

Abstract
The invention provides a body-worn monitor featuring a processing system that receives a digital data stream from an ECG system. A cable houses the ECG system at one terminal end, and plugs into the processing system, which is worn on the patient'"'"'s wrist like a conventional wristwatch. The ECG system features: i) a connecting portion connected to multiple electrodes worn by the patient; ii) a differential amplifier that receives electrical signals from each electrode and process them to generate an analog ECG waveform; iii) an analog-to-digital converter that converts the analog ECG waveform into a digital ECG waveform; and iv) a transceiver that transmits a digital data stream representing the digital ECG waveform (or information calculated from the waveform) through the cable and to the processing system. Different ECG systems, typically featuring three, five, or twelve electrodes, can be interchanged with one another.
