Fluidly Isolated Pump Control Unit for Wound Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reduced-pressure medical treatment systems face challenges in maintaining the integrity and reusability of high-value components due to contamination risks, particularly in wound therapy, where the pump control unit is often exposed to fluids, leading to potential contamination and limited recyclability of the canister unit.
Innovation Solution
A reduced-pressure treatment system design featuring a fluidly isolated pump control unit separate from the canister unit, with a linking interface that provides energy to the pump head to generate reduced pressure without direct fluid communication, preventing contamination and allowing for the reuse of high-value components while making the canister unit disposable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pump control unit is integrated with the canister unit and exposed to fluids, then the system structure is simplified, but the pump control unit becomes contaminated and cannot be reused
Solution Approach 1:
The system is divided into two separate units: a disposable canister unit that contacts fluids and a reusable pump control unit that remains fluidly isolated. This segmentation allows the pump control unit to be protected from contamination while the canister unit can be discarded after single use, resolving the contradiction between structural simplicity and reusability.
Solution Approach 2:
A fluid communication interface acts as an intermediary between the canister unit and pump control unit, allowing fluid transfer while maintaining fluid isolation. This intermediary enables the pump control unit to control the canister unit without direct fluid contact, preserving reusability while maintaining functional integration.
2Loss of substance
If the canister unit is designed to be reusable, then cost is reduced, but it becomes contaminated and requires complex cleaning procedures
Solution Approach 1:
The canister unit is designed as a disposable, single-use component that is discarded after one use. This eliminates the need for complex cleaning and sterilization procedures while keeping the overall cost effective, as only the low-cost canister unit is replaced rather than the entire system.
3Reliability
If the pump control unit is fluidly isolated from the canister unit, then contamination is prevented, but the device complexity increases
Solution Approach 1:
The system is segmented into a reusable pump control unit and a disposable canister unit with a defined fluid communication interface. This segmentation achieves contamination prevention through fluid isolation while managing complexity by allowing each unit to be optimized independently for its specific function.

Function Achieved in This Case
This design effectively prevents contamination of the pump control unit, facilitates the reuse of high-value components, and allows for the disposable nature of the canister unit, enhancing the system's efficiency and hygiene in wound therapy applications.
