General-purpose medical instrumentation
First Claim
1. A method of remotely monitoring a plurality of patients, comprising the steps of:
- configuring a plurality of data-collection environment (DCE) nodes into a hierarchical communications network architecture, each DCE node being operative to tag received physiologic data with time and source identifiers regarding the patient, or the source of origin of the data, and the time at which the data was collected, the DCE nodes including a plurality of patient-monitoring nodes and at least one data-viewing node, each patient-monitoring node including a portable, wearable 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;
tagging the collected data with time and source identifiers so that the data are self-descriptive;
packetizing the tagged data by segmenting the data into discrete packets;
feeding the packetized data to the communications network; and
wherein each data-viewing node enables a clinician to access and view the physiologic data from any other node in the communications network in a time-ordered manner even if the data arrived at a time, or in a time order, different than the time or order in which it was collected at the patient-monitoring nodes; and
at least a portion of the hierarchical communications network architecture is wireless.

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.
