Solution Overview
Problem
Existing systems for generating patient medical parameter Flowsheets lack sufficient user examination, editing, validation, and selection capabilities, limiting their accuracy and representativeness of patient conditions.
Innovation Solution
A user interface system with a zoom window function that allows users to examine, validate, edit, and select data points within specific acquisition time intervals, enabling improved accuracy of trend indicative patient parameter data for storage or display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If known systems generate Flowsheets with automatic data point selection, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The system performs preliminary actions by generating an initial Flowsheet with automatically selected data points, then prepares expanded acquisition time intervals with additional data points before user interaction. This allows the system to provide a quick initial display while having refined data ready for user validation, resolving the contradiction between fast generation and high precision.
Solution Approach 2:
The invention introduces an intermediary mechanism - the expanded acquisition time interval window - that sits between automatic data selection and final Flowsheet generation. This window displays additional data points that serve as a mediator, allowing users to review and validate data before final incorporation, thus improving precision without sacrificing productivity.
2Device complexity
If known systems provide limited user examination capabilities, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The user interface is segmented into distinct functional areas: the main Flowsheet display and the expanded acquisition time interval window. This segmentation allows complex examination and validation functions to be organized into manageable, separate sections, maintaining interface simplicity while enhancing reliability through structured data review capabilities.
Solution Approach 2:
The invention adds another dimension to the user interface by introducing the expanded acquisition time interval window as a supplementary view. This additional dimensional space allows users to examine data points in greater detail without cluttering the main Flowsheet display, thereby improving reliability while preserving interface simplicity.
3Ease of operation
If Flowsheets display aggregated data points, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The system extracts additional data point details from the aggregated Flowsheet display and places them in the separate expanded acquisition time interval window. This extraction allows the main Flowsheet to remain simple and readable while preserving access to detailed information in the expanded window, thus reducing information loss without compromising ease of operation.

AI summary
A user interface system provides patient medical parameter data for trend indicative display covering a time period comprising user selectable acquisition time intervals. An acquisition processor acquires, from a patient monitoring device, data representing a patient parameter comprising a plurality of data values at a corresponding plurality of different times within multiple user selectable patient parameter acquisition intervals of a time period. A generator generates data representing a first image showing a trend indicative display of the patient parameter covering a time period comprising user selectable acquisition time intervals and including a first number of data points in an individual acquisition time interval. The generator generates data representing an image window comprising an expansion of the individual acquisition time interval and including a second number of data points greater than the first number, in response to user command. The generator updates the individual acquisition time interval of the first image with at least one data point selected from the expanded individual acquisition time interval window to replace the first number of data points, in response to user command.
