Medical System for Automatic Therapy Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current healthcare systems for managing chronic heart failure require physician input to adjust therapy, which can lead to delays in responding to a patient's deteriorating health conditions without direct physician contact.
Innovation Solution
A system comprising an implantable medical device and a wearable device that acquire signals and generate data transmissions, processed to compare against thresholds, determine worsening heart failure episodes, and automatically adjust therapy without direct physician intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physician input is required to adjust therapy, then therapy adjustment accuracy is improved, but response time to deteriorating health conditions worsens
Solution Approach 1:
The system enables automatic therapy adjustment by the medical device itself based on sensed physiological parameters. The device autonomously compares sensed data against thresholds and modifies therapy settings without requiring external physician intervention, thus resolving the contradiction between rapid response and accurate adjustment.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where the device continuously senses physiological parameters, compares them against predetermined thresholds, and automatically adjusts therapy based on the comparison results. This feedback loop enables both rapid response and maintained accuracy through algorithmic decision-making.
2Reliability
If direct physician contact is required for therapy adjustment, then medical oversight quality is improved, but system complexity and ease of operation worsen
Solution Approach 1:
The medical device performs self-adjustment of therapy parameters based on automated analysis of physiological data. This eliminates the need for direct physician contact for routine adjustments, greatly simplifying operation while maintaining reliable oversight through programmed clinical guidelines and threshold-based decision logic.
3Loss of time
If automatic therapy adjustment is implemented, then response time is improved, but device complexity increases
Solution Approach 1:
The automatic adjustment system uses a feedback-controlled architecture where physiological parameters are sensed, compared against thresholds, and used to trigger predetermined therapy modifications. This structured approach enables rapid automated response while managing complexity through rule-based decision-making rather than requiring complex artificial intelligence.
Data Source
AI summary
Methods and systems for seamless adjustment of treatment are disclosed. A determination can be made as to whether to intervene with a patient's treatment based on data obtained from implantable electrodes and/or non-implantable electrodes. The data from non-implantable electrodes have a correction factor applied to adjust for less accuracy compared to data acquired from implantable electrodes.
