Wireless Blood Flow Restriction Cuff with Automated Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood flow restriction training (BFRT) cuffs require manual inflation/deflation and use of manual pressure gauges, making them inconvenient to use during training, and there is a need for a more user-friendly, wireless monitoring and control system that can maintain specific limb occlusion pressure.
Innovation Solution
A BFRT system with a motor/pump unit that includes a housing, motor, pump, displays, and sensors to wirelessly control and monitor air pressure in inflatable chambers, allowing for automatic adjustment and maintenance of limb occlusion pressure, and can be controlled manually or via a computer, tablet, or smartphone app.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual inflation/deflation and manual pressure gauges are used in BFRT cuffs, then the device complexity is reduced and manufacturing cost is lowered, but the ease of operation deteriorates and user convenience is reduced
Solution Approach 1:
The patent replaces manual mechanical inflation/deflation operations with an automated motor/pump unit that electronically controls air pressure in the cuff. This motorized system eliminates the need for manual pumping while integrating pressure sensors and wireless communication capabilities to provide automated pressure regulation and monitoring, thereby improving ease of operation despite increased device complexity
Solution Approach 2:
The BFRT cuff system incorporates automated pressure regulation through integrated motor/pump units and pressure sensors that automatically maintain predetermined pressure levels without requiring continuous manual intervention. The system can autonomously inflate, deflate, and adjust pressure based on sensor feedback and programmed parameters, enabling self-service operation that improves user convenience
2Productivity
If automated motor/pump units with wireless monitoring are integrated into BFRT cuffs, then the ease of operation and training efficiency are improved, but the device complexity increases and manufacturing cost rises
Solution Approach 1:
The motor/pump unit is designed as a multi-functional integrated component that combines motorization for inflation/deflation, pressure sensing capabilities, wireless communication interfaces, and control logic within a single unit. This consolidation allows the system to perform multiple functions (pressure regulation, data monitoring, wireless communication) without proportionally increasing complexity, thereby improving training efficiency through automated operation and real-time monitoring

AI summary
A BFRT cuff and motor/pump unit and a method for exercising using said cuff. The method incudes providing a BFRT cuff and a motor/pump unit, placing the BFRT cuff on a user's limb, connecting the BFRT cuff to the motor/pump unit, selecting a pressure value or percent of limb occlusion pressure (LOP), causing the motor/pump unit to supply air to the BFRT cuff until the LOP of said limb is obtained, terminating air flow to the BFRT cuff and then reducing the pressure in the BFRT cuff, and exercising the user's limb while the BFRT cuff is at a selected pressure or a selected percent of LOP.
