Parallel Eavesdropper for Aortic Blood Pressure Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring distal blood pressure in patients with stenosis require disconnecting and reconnecting pressure signal connectors, leading to tedious recalibration and calibration steps, which is inefficient and undesirable.
Innovation Solution
An eavesdropper system with a communication interface and receiver that connects in parallel with the central monitoring device, allowing it to access and monitor aortic blood pressure signals without affecting the pressure signal, reducing the need for recalibration and minimizing cabling by using wired and/or wireless channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a second sensor is connected to a smaller monitoring device which relays signals to the cathlab monitor, then distal blood pressure can be measured, but connectors carrying pressure signals must be disconnected and reconnected, requiring recalibration
Solution Approach 1:
The patent introduces an intermediary device (the smaller monitoring device with relay functionality) that acts as a mediator between the second sensor and the cathlab monitor. This intermediary captures pressure signals directly from the sensor and relays them to the monitor, eliminating the need to disconnect and reconnect connectors, thus avoiding recalibration while maintaining measurement capability
Solution Approach 2:
The smaller monitoring device creates a copy of the pressure signal path by directly capturing signals from the second sensor and relaying them to the cathlab monitor. This signal copying mechanism allows parallel monitoring without interrupting the original signal flow, thereby eliminating the need for connector disconnection and recalibration
2Adaptability or versatility
If connectors are disconnected and reconnected to use a smaller monitoring device, then additional functionality is obtained, but the process is tedious and time-consuming
Solution Approach 1:
The system maintains continuous signal flow from the second sensor through the smaller monitoring device to the cathlab monitor without interruption. The intermediary device enables continuous monitoring and signal transmission, eliminating the need to stop the process for connector disconnection and recalibration, thus saving time while preserving adaptability
3Measurement precision
If pressure signal connectors are disconnected for recalibration, then measurement accuracy can be maintained, but this is an undesired procedure
Solution Approach 1:
The smaller monitoring device performs self-service by automatically capturing pressure signals from the second sensor and relaying them to the cathlab monitor without requiring manual intervention for connector disconnection and recalibration. This automated signal relay maintains measurement precision while eliminating the complex recalibration procedure

AI summary
The present disclosure relates to a blood pressure measurement and communication system configured to receive a signal representing a measured aortic blood pressure value from an aortic pressure sensor and provide the signal to a monitoring device and to a receiver. The system is further configured to receive a signal representing a measured distal blood pressure value from a distal pressure sensor, convert the signal and provide the signal the receiver. By means of the blood pressure signals, FFR can be calculated.
