Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wound treatment technologies, such as negative pressure wound therapy, face challenges in efficiently managing wound dressings and fluid delivery systems, particularly in terms of compatibility and automation for optimal tissue healing.
Innovation Solution
The development of pump cassettes with movable diaphragms and integrated identifiers, such as RFID tags, that can be coupled with wound-treatment apparatuses to apply negative pressure and deliver fluids to wounds, along with automated readers to determine properties and activate actuators for precise fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual management of wound dressings and fluid delivery systems is used, then device complexity is reduced, but productivity and precision of fluid management deteriorate
Solution Approach 1:
The system enables automated identification and management of pump cassettes through RFID tags. The automated reader detects the RFID tag, retrieves cassette properties, and configures the actuator automatically, eliminating manual setup and reducing human intervention in fluid management processes
Solution Approach 2:
Manual mechanical management of pump cassettes is replaced with an automated electronic system using RFID identification and electronic communication between the reader, controller, and actuator, thereby increasing precision and efficiency while reducing manual labor
2Measurement precision
If pump cassettes without identifiers are used, then device complexity is reduced, but measurement precision and automation capability deteriorate
Solution Approach 1:
Physical inspection and manual identification of pump cassette properties are replaced with automated RFID electromagnetic field-based identification, enabling precise retrieval of cassette properties including diaphragm diameter, area, stroke, and volume change without manual measurement
Solution Approach 2:
The RFID tag serves as an intermediary carrier that stores and transmits pump cassette properties electronically, enabling the automated reader to accurately detect and retrieve information without direct physical contact or manual intervention
3Adaptability or versatility
If fixed pump cassettes are used, then device complexity is reduced, but adaptability and ease of repair deteriorate
Solution Approach 1:
The wound treatment apparatus is segmented into a reusable housing and replaceable pump cassettes. This modular design allows the pump cassette to be removed and replaced independently, facilitating ease of repair and adaptability when diaphragms wear or need upgrading
Solution Approach 2:
The pump cassette design transitions from a fixed configuration to a dynamic, replaceable configuration. The removable coupling allows the system to adapt to different treatment requirements and enables easy replacement of worn components without replacing the entire apparatus

AI summary
Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.
