Abstract
A system is disclosed having a storage, a communications module for interacting with a medical measurement device, an analysis controller, and a test module that allows for the testing and evaluating of decision-support algorithms. A method for testing decision-support algorithms is disclosed having the steps of receiving into storage of a ruggedized, compact computer at least one decision-support algorithm; detecting with a communications module the initiation of a vital-sign monitoring session; receiving and storing vital-sign information into storage by the communications module; pushing the stored vital-sign information by an analysis controller to a test module running the stored at least one decision-support algorithm; and providing at least one output from the decision-support algorithm to at least one of a database and a display.
Core Innovation
The invention provides a system and method for developing, testing, and evaluating decision-support algorithms in a portable, ruggedized, compact computer that receives vital-sign data from an external source such as a vital-sign monitor. The system includes a storage for storing vital-sign data and at least one decision-support algorithm, a communications module for receiving and storing vital-sign data, an analysis controller that monitors the storage, and a test module that runs the stored algorithms on the received data to produce outputs.
This system addresses the problem that existing decision-support algorithms are typically embedded and proprietary to vital-sign monitors or medical recording systems, which restricts easy modification or refinement by end users and complicates testing of new algorithms. Most existing approaches utilize retrospective analysis on workstations or servers, limiting real-time testing and portability.
Claims Coverage
The patent claims disclose two independent system claims covering a ruggedized, compact system for receiving and processing vital-sign data using decision-support algorithms, and inventive features related to its components and functionality.
Integrated system for storing and processing vital-sign data with decision-support algorithms
A system comprising a storage configured to store at least one algorithm; a communications module for receiving vital-sign data from an external source and storing it in the storage; an analysis controller that monitors the storage; and a test module which receives vital-sign data from the storage through the analysis controller, runs at least one loaded algorithm to process the data, stores the algorithm output in storage, all enclosed in a ruggedized, compact housing.
Real-time output generation from vital-sign data processing
The test module's running means processes at least a portion of the vital-sign data to provide output in substantially real time from receipt of the data by the communications module, allowing timely decision support within the compact system.
The independent claims cover a compact, ruggedized system designed to receive, store, analyze, and run decision-support algorithms on vital-sign data in real time with modular components including communications, storage, analysis control, and testing modules enclosed within a single housing.
