Challenge
As a critical component of the Dual Channel Tourniquet Device, this project required developing a compact, highly reliable pump sub-assembly. The pump needed to provide consistent air pressure to the tourniquet system while maintaining precise control necessary for surgical applications.
Technical Hurdles
- Achieving consistent pressure accuracy across operational conditions
- Designing for vibration isolation to minimize noise in surgical environments
- Ensuring reliability throughout surgical procedures of varying duration
- Creating a compact design that integrated seamlessly with the main tourniquet device
- Developing mounting solutions that minimized vibration transfer
Approach
- Drive mechanism analysis: Multiple pump technologies were evaluated for precision, reliability, and size
- Component life testing: Critical components underwent accelerated life testing to ensure durability
- Vibration isolation: Custom mounting systems were designed to minimize operational noise
- System integration: The sub-assembly was optimized for seamless integration with the main tourniquet device
- Design for assembly: Manufacturing processes were streamlined through sub-assembly construction to ensure consistent performance
Outcome
The pump sub-assembly achieved the pressure consistency required for the tourniquet system while maintaining a compact form factor suitable for integration within the main device. The design incorporated effective vibration dampening for quiet operation in surgical settings.
By breaking down the manufacturing process into efficient sub-assemblies, the team improved production workflow while ensuring consistent quality. The methodical approach to addressing the challenges of creating a reliable and precise pneumatic pump for surgical applications resulted in a key component that directly contributed to the overall effectiveness of the dual channel tourniquet system.
