Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current artificial heart pumps that indirectly measure flow lack remote monitoring capabilities, limiting dynamic adjustment and oversight, leading to suboptimal performance and increased risk of complications due to infrequent clinical supervision.
Innovation Solution
A diagnostic device that attaches to the heart pump controller to continuously query and transmit data on power consumption and operating variables, allowing remote monitoring and analysis of heart pump performance using wireless technology, enabling expert oversight and real-time decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If indirect flow measurement technology is used in implanted artificial heart pumps, then the number of direct sensor components is reduced and reliability is improved, but remote monitoring capability is lost and device complexity increases
Solution Approach 1:
The patent extracts the monitoring function from the pump itself and places it in an external portable device. The pump maintains a simple indirect measurement system with fewer components, while the external device handles all data processing, wireless transmission, and display functions. This separation reduces pump complexity and improves reliability while enabling remote monitoring.
Solution Approach 2:
The portable external device acts as an intermediary between the pump and the user/clinician. It receives data from the pump's indirect measurement system, processes the information, and provides the interface for monitoring and control. This intermediary layer enables remote monitoring without adding complexity to the implanted pump.
2Measurement precision
If a portable controller is attached to a larger monitor for real-time flow measurements, then measurement precision is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent merges the portable controller and monitor functions into a single integrated external device. This unified design maintains the measurement precision of the original system while eliminating the need for separate components, thereby improving portability and ease of operation for patients using the pump at home.
3Productivity
If heart pump operates at high motor rotating speeds, then productivity is improved, but harmful factors increase due to suction problems
Solution Approach 1:
The patent implements a feedback system where the portable device continuously monitors pump operating parameters including motor speed and flow. The system provides real-time feedback to alert users and clinicians when operating conditions approach dangerous thresholds, enabling dynamic adjustment to prevent suction complications while maintaining optimal pump performance.
