Current enteral feeding systems face challenges in ensuring accurate and consistent delivery of nutrition to patients due to gaps in communication and varying patient needs, leading to potential malnutrition and increased health complications.
Innovation Solution
An enteral feeding apparatus and system that includes a controller and pump, which calculates and adjusts the delivery rate of enteral feeding formula based on individual patient caloric requirements using established equations, monitors caloric intake, and implements a compensatory bolus protocol to address underfeeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single enteral feeding pump is shared among multiple patients, then device utilization efficiency is improved, but the risk of improper feeding increases due to programming errors
Solution Approach 1:
The system automatically captures patient demographics and calculates caloric requirements, then continuously monitors delivered calories and compares them against targets. This closed-loop feedback ensures accurate feeding delivery even when the pump is shared among multiple patients, eliminating the need for manual re-programming and preventing programming errors.
Solution Approach 2:
The pump system performs automatic patient identification, caloric requirement calculation, and delivery monitoring without requiring manual intervention. The system self-adjusts based on patient-specific parameters and automatically tracks compliance, reducing human error while maintaining high device utilization.
2Adaptability or versatility
If manual monitoring and adjustment of feeding rates is performed, then flexibility in responding to patient needs is improved, but the risk of communication gaps and underfeeding increases
Solution Approach 1:
The system continuously monitors actual calorie delivery and compares it against patient-specific targets, automatically alerting providers when underfeeding is detected. This real-time feedback ensures consistent nutrition delivery while maintaining the ability to respond to patient needs through automated adjustments and provider notifications.
Solution Approach 2:
The patent replaces manual monitoring and communication processes with an automated electronic system that calculates requirements, tracks delivery, and communicates status to providers. This substitution eliminates communication gaps while maintaining adaptability through automated response to patient-specific parameters.
3Ease of operation
If frequent interruptions occur to change patient position or administer medications, then patient care quality is improved, but enteral nutrition delivery is compromised
Solution Approach 1:
The system automatically tracks interruptions and calculates their impact on total calorie delivery. When underfeeding is detected due to interruptions, the system can automatically adjust future delivery rates or extend feeding duration to compensate, ensuring nutrition goals are met despite necessary patient care interruptions.
Solution Approach 2:
The feeding system dynamically adjusts delivery parameters based on actual patient needs and interruptions. The system can modify rate and timing in real-time to accommodate position changes and medication administration while ensuring total caloric requirements are met, balancing care flexibility with nutrition consistency.
4Measurement precision
If complex calculations for individualized caloric requirements are performed manually, then precision in meeting patient needs is improved, but time consumption and staff workload increase
Solution Approach 1:
The pump system automatically performs all caloric requirement calculations using patient demographics and standard equations (e.g., Harris-Benedict). The system self-determines target calories, delivery rates, and monitoring parameters without requiring staff time for manual calculations, achieving high precision while eliminating time consumption.
Solution Approach 2:
The patent replaces manual calculation processes with automated electronic computation embedded in the pump system. The system automatically retrieves patient data, applies nutritional equations, and generates individualized feeding prescriptions, eliminating staff workload while maintaining calculation precision.
