Implantable Blood Pump Remote Controller Update System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable blood pumps require shutdown for electronic updates, posing a hazard to patients due to the interruption of blood flow.
Innovation Solution
A remote controller updating system that includes a data network connection between the implantable controller and remote controller, allowing for system updates while maintaining the blood pump in continuous operation through a power source and magnetic coupling, enabling updates without stopping the blood pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blood pump is stopped for electronic updates, then the remote controller can be updated, but blood flow is interrupted which is hazardous to the patient
Solution Approach 1:
The system separates the update function from the power supply function by introducing a dedicated system update connector distinct from the controller connector. This allows the remote controller to be updated independently while the blood pump continues to receive power and operate normally, resolving the contradiction between patient safety and update capability.
Solution Approach 2:
The system update assembly acts as an intermediary device that provides both power supply and update capabilities during the update process. This mediator enables controller updates without requiring pump shutdown, as it maintains power flow through the pump while facilitating data transfer to the controller.
2Reliability
If a dedicated update connector is added, then updates can occur without stopping the pump, but device complexity increases
Solution Approach 1:
The system update connector is designed with multi-functionality, serving both as a power supply interface and a data transfer interface during updates. This universal design reduces the need for completely separate systems while enabling continuous operation during updates, balancing reliability improvement with controlled complexity increase.
3Ease of operation
If the remote controller is updated while connected, then updates can be performed, but power supply interruption may occur
Solution Approach 1:
The system separates power supply and data update pathways by using distinct connectors - the controller connector for power and the system update connector for updates. This segmentation allows update operations to proceed without interrupting the power supply to the blood pump, maintaining reliability while enabling ease of operation.
Solution Approach 2:
The system ensures continuous power supply to the blood pump during controller updates by maintaining the power connection through the controller connector while performing updates through the separate system update connector. This continuity of useful action prevents power interruption and maintains pump operation throughout the update process.
