Wearable ECG-Blood Pressure Sequencing for Missed Measurement Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients often forget to measure either electrocardiogram readings or blood pressure after receiving an alert for measurement.
Innovation Solution
A measurement device that automatically initiates blood pressure measurement after electrocardiogram measurement without user input, includes a notification unit to alert the user, and optionally includes a posture detection unit to ensure accurate blood pressure measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a patient uses an alert function to remind measurement, then the patient can be reminded to measure, but the patient may still forget to measure one of the measurements after completing the other
Solution Approach 1:
The system performs preliminary action by automatically initiating the second measurement (blood pressure) immediately after detecting completion of the first measurement (ECG). This eliminates the need for the user to manually start the second measurement, ensuring both measurements are completed without forgetting.
Solution Approach 2:
The system provides feedback by notifying the user when one measurement is completed and automatically triggering the next measurement. This feedback loop ensures the user is aware of measurement status and that the measurement sequence is proceeding correctly, improving completion reliability.
2Ease of operation
If the measurement device waits for user instruction to start each measurement, then the user has control over measurement timing, but the user may forget to initiate the second measurement
Solution Approach 1:
The measurement device performs self-service by automatically detecting when the first measurement is completed and autonomously initiating the second measurement without requiring user intervention. This self-service mechanism ensures both measurements are completed while reducing the operational burden on the user.
3Productivity
If the blood pressure measurement starts immediately after ECG measurement, then measurement efficiency is improved, but the user may not be in the appropriate posture for accurate blood pressure measurement
Solution Approach 1:
The system performs preliminary action by notifying the user in advance that blood pressure measurement will start and providing guidance on proper posture. This allows the user to prepare appropriately before the measurement begins, ensuring both efficiency and accuracy.
Solution Approach 2:
The system provides feedback to the user about measurement status and posture requirements. This feedback ensures the user understands what is needed for accurate measurement while maintaining the automated sequence that improves efficiency.
