Removable Blood Pump Controller for Portable Circulatory Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circulatory support devices and systems face challenges in providing flexible and efficient operation, particularly in emergency and transport scenarios, due to the need for bulky consoles and fixed connections to power and control units.
Innovation Solution
A removable controller for blood pumps that can be easily coupled and decoupled from a console, allowing wireless or wired communication, and equipped with a rechargeable battery for independent operation, enabling seamless transport and uninterrupted monitoring/control of the blood pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed console with wired connections is used to control the blood pump, then reliable control and monitoring is achieved, but device portability and ease of transport is reduced
Solution Approach 1:
The system is divided into separate modules: a fixed console for stable control and a removable controller for portable operation. The removable controller can be detached from the console, allowing the blood pump to be controlled in portable settings while maintaining reliable control when docked with the console. This segmentation enables the system to switch between fixed and portable modes as needed.
2Adaptability or versatility
If a removable controller with battery is used, then device portability and flexibility is improved, but continuous power supply reliability may be reduced
Solution Approach 1:
The removable controller acts as an intermediary between the battery power source and the blood pump. It includes a processor that manages power distribution and can switch between battery power and console power. This intermediary ensures continuous reliable operation by seamlessly transitioning between power sources without interrupting blood pump function.
Solution Approach 2:
The removable controller includes a rechargeable battery that is charged in advance when docked with the console. This preliminary charging ensures that when the controller is removed for portable use, sufficient power is already stored to maintain blood pump operation without interruption. The system proactively prepares power availability rather than reacting to power needs.
3Ease of operation
If wireless communication is implemented between controller and console, then ease of movement is improved, but communication reliability and data transmission stability may be reduced
Solution Approach 1:
The communication system dynamically switches between wireless and wired modes based on operational needs. When the removable controller is docked with the console, wired communication is used for stable data transfer. When removed for portable use, wireless communication enables movement freedom. The system adapts its communication method to the current operational context, maintaining reliability in each mode.

AI summary
A circulatory support system may include a blood pump and a removable controller configured to control operation of the blood pump and be removably coupled to a console. The removable controller comprising a display configured to display status indicators corresponding to parameters related to operation of the blood pump; speed controls configured to control a speed of the blood pump; a first connector configured to communicatively couple the removable controller with the blood pump; and a second connector configured to communicatively couple the removable controller with the console.
