General-purpose medical instrumentation
First Claim
1. A system for communicating medical information, comprising:
- a plurality of portable, wearable patient monitors, each patient monitor including one or more sensors, each sensor being operative to collect physiologic data at a data collection rate and at a data collection time;
each portable, wearable patient monitor further including a processor operative to tag the collected data with a time stamp and source identifiers so that the data are self-descriptive, packetize the tagged data by segmenting the data into discrete packets, and feed the packetized data to a hierarchical communications network having a common system time base;
one or more data-viewing stations interfaced to the communications network; and
wherein the time stamp of the collected data corresponds to the common system time base associated with the common system time base of the hierarchical communications network, thereby enabling a user of each data-viewing station to access and view the physiologic data from multiple points of origin or patients in a time-ordered manner even if the packets associated with the physiologic data arrived at a time, or in a time order, different than the time or order in which it was collected by the patient monitors.

Abstract
A general-purpose, low-cost system provides comprehensive physiological data collection, with extensive data object oriented programmability and configurability for a variety of medical as well as other analog data collection applications. In a preferred embodiment, programmable input signal acquisition and processing circuits are used so that virtually any analog and/or medical signal can be digitized from a common point of contact to a plurality of sensors. A general-purpose data routing and encapsulation architecture supports input tagging and standardized routing through modern packet switch networks, including the Internet; from one of multiple points of origin or patients, to one or multiple points of data analysis for physician review. The preferred architecture further supports multiple-site data buffering for redundancy and reliability, and real-time data collection, routing, and viewing (or slower than real-time processes when communications infrastructure is slower than the data collection rate). Routing and viewing stations allow for the insertion of automated analysis routines to aid in data encoding, analysis, viewing, and diagnosis.
