Medical Device Displaying Filtered Physiological Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical devices struggle to accurately assess patient conditions due to artifacts caused by treatments, which can lead to misinterpretation of physiological parameters, potentially causing incorrect diagnoses or treatments.
Innovation Solution
A medical device that generates filtered data by removing treatment-related artifacts from unfiltered data and simultaneously displays both filtered and unfiltered data, allowing users to assess the patient's condition more accurately by emphasizing reliable data based on the treatment context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If filtered data is displayed to remove treatment artifacts, then measurement precision is improved, but loss of information occurs when filtered data obscures actual patient conditions
Solution Approach 1:
The patent segments the displayed data into multiple representations: filtered data (with artifacts removed) and unfiltered data (with artifacts present). This allows the system to provide both the cleaned signal for accurate measurement and the original signal for contextual information, resolving the contradiction between precision and information completeness.
Solution Approach 2:
The patent introduces an intermediary display mechanism that presents both filtered and unfiltered data simultaneously or selectively. This intermediary layer allows users to access both the precision of filtered data and the contextual information of unfiltered data without the harmful effects of artifact removal being lost.
2Reliability
If both filtered and unfiltered data are displayed simultaneously, then reliability is improved through user assessment, but device complexity increases
Solution Approach 1:
The patent implements dynamic display capabilities where the system can switch between displaying only filtered data, only unfiltered data, or both simultaneously based on user needs and treatment context. This dynamic approach maintains reliability by providing comprehensive data while managing complexity through adaptive rather than static display configurations.
Solution Approach 2:
The patent creates a multi-functional display system that can serve multiple purposes: displaying filtered data for precision measurement, displaying unfiltered data for contextual information, and selectively displaying both for comprehensive assessment. This universal display capability improves reliability across different clinical scenarios while managing system complexity through flexible rather than dedicated configurations.

AI summary
An example method is performed by a medical device and includes detecting an analog signal indicating a physiological parameter of a subject; converting the analog signal to first data; and determining a treatment parameter characterizing a treatment administered to the subject by a second medical device. The method further includes generating a filter characterized by the treatment parameter; generating second data by applying the filter to the first data; and displaying, on a user interface, the first data and the second data, wherein the second data is emphasized on the user interface.
