BODY-WORN VITAL SIGN MONITOR
First Claim
1. A system for measuring vital sign information from a patient, comprising:
- (a) a first sensor configured to generate a first time-dependent waveform indicative of one or more contractile properties of the patient'"'"'s heart;
(b) a second sensor configured to generate a second time-dependent waveform indicative of one or more contractile properties of the patient'"'"'s heart; and
(c) a processing component configured to be worn on the patient'"'"'s body and comprising a microprocessor, a system for detecting an identifying code from a medical professional, and an interface to both the first and second sensors, the processing component configured to;
(i) receive a first signal representing the first time-dependent waveform through a first interface;
(ii) receive a second signal representing the second time-dependent waveform through a second interface;
(iii) calculate at least one vital sign value from at least one of the first and second signals or versions thereof; and
(iv) display the vital sign value on a first graphical user interface rendered in response to detecting the identifying code.

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.
