Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing enteral feeding pumps struggle to accurately adjust flow rates and delivery protocols based on the varying characteristics of different nutritional liquids, such as viscosity and caloric content, leading to potential errors in fluid administration.
Innovation Solution
The integration of an identification member on the feeding set that represents nutritional liquid characteristics, allowing the enteral feeding pump to automatically identify these characteristics and adjust flow rates and delivery protocols accordingly, using a processor and reader system to ensure precise fluid delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the enteral feeding pump uses a standard peristaltic pumping mechanism, then the pump can deliver fluids at a controlled rate, but it cannot automatically adapt to varying characteristics of different nutritional liquids such as viscosity and caloric content
Solution Approach 1:
The identification member with encoded nutritional liquid characteristics is attached to the feeding set before use. The pump reads this information in advance and pre-configures the delivery parameters, allowing the system to adapt to different liquid characteristics without requiring complex real-time sensing or adjustment mechanisms.
Solution Approach 2:
An identification member serves as an intermediary between the nutritional liquid and the pump control system. This mediator carries encoded information about the liquid's characteristics, enabling the pump to adapt its delivery parameters without direct sensing of the liquid properties, thus maintaining simple pump hardware while achieving adaptability.
2Reliability
If the pump manually adjusts flow rates for different nutritional liquids, then delivery accuracy can be maintained, but the likelihood of human error increases and compliance with treatment regimens decreases
Solution Approach 1:
The system performs self-configuration by automatically reading the identification member and setting the appropriate delivery parameters based on the nutritional liquid's characteristics. This eliminates the need for manual adjustment by the operator, reducing human error while maintaining delivery accuracy, and simplifies operation to merely attaching the pre-configured feeding set.
Solution Approach 2:
The identification member provides feedback information about the nutritional liquid characteristics to the pump's control system. This feedback loop enables automatic adjustment of delivery parameters, ensuring accurate fluid administration without requiring manual intervention or complex operator judgment.
3Productivity
If the pump delivers fluid at a fixed flow rate, then the pumping mechanism is simple, but it cannot account for variations in viscosity and other characteristics of different nutritional liquids
Solution Approach 1:
The optimal delivery parameters are predetermined and encoded on the identification member based on the specific nutritional liquid's characteristics. The pump simply reads and executes these pre-calculated parameters, achieving optimized delivery efficiency without requiring complex real-time control algorithms or sensing systems.

AI summary
A feeding set for use with a peristaltic enteral feeding pump to deliver nutritional liquid fluid to a patient includes a container having nutritional liquid. A conduit assembly includes tubing placeable in fluid communication with the container and adapted for mounting on the enteral feeding pump. The tubing provides a fluid pathway for delivering the nutritional liquid from the container to a patient when the tubing is mounted on the enteral feeding pump. An identification member is mounted on the conduit assembly and has at least one characteristic of a nutritional liquid associated with the feeding set represented by the identification member. The identification member is positioned on the conduit assembly so as to permit automatic identification by the enteral feeding pump of the at least one characteristic of the nutritional liquid upon mounting the conduit assembly on the enteral feeding pump.
