Premix Compounding Workflow for Error-Safe Parenteral Nutrition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for compounding parenteral nutrition formulations are prone to errors and contamination due to manual calculations and handling, especially in high-stress hospital environments, where complex calculations and multiple ingredients increase the risk of mistakes and microbial contamination.
Innovation Solution
An automated compounder system that reduces human interaction by preprogrammatically controlling the delivery of additives to a receiving receptacle, using a single fluid interconnection and verifying the receptacle's identity and volume to ensure accurate and safe compounding, minimizing errors and contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual calculations and handling are used for compounding parenteral nutrition formulations, then flexibility in customization is maintained, but error rates increase and contamination risks escalate
Solution Approach 1:
The system enables self-service automation where the compounder autonomously performs calculations, verifies ingredient compatibility, controls delivery volumes, and monitors compounding progress without human intervention, thereby eliminating manual errors while maintaining customization capability
Solution Approach 2:
The patent replaces manual mechanical handling with an automated computer-controlled system that uses electronic manifests, automated calculations, and programmable delivery mechanisms to compound formulations, substituting human operations with automated digital processes
2Object-affected harmful factors
If multiple fluid interconnections are made during manual compounding, then ingredient additions are flexible, but contamination opportunities increase
Solution Approach 1:
The system merges multiple separate fluid interconnection operations into a single integrated automated process where all ingredient deliveries are managed through one established fluid pathway, eliminating repeated connection/disconnection cycles and associated contamination risks
Solution Approach 2:
The automated system maintains continuous fluid connection throughout the compounding process, allowing seamless delivery of multiple ingredients without breaking the sterile barrier, thereby eliminating contamination opportunities while maintaining operational flexibility
3Reliability
If automated compounder systems are implemented, then error rates decrease and patient safety improves, but system complexity increases
Solution Approach 1:
The automated compounder system performs multiple functions including manifest processing, automated calculations, ingredient compatibility verification, precise volume delivery, and compounding monitoring within a single integrated platform, reducing overall system complexity despite enhanced capabilities
Solution Approach 2:
The system uses an electronic manifest as an intermediary that carries all compounding instructions, calculations, and verification data, serving as a central communication hub that coordinates all automated functions and simplifies the overall system architecture
4Productivity
If manual compounding protocols are used, then adaptability to individual patient needs is maintained, but productivity decreases due to time-consuming calculations and handling
Solution Approach 1:
The system performs preliminary automated calculations of ingredient volumes and concentrations based on electronic patient-specific manifests before actual compounding begins, eliminating time-consuming manual computations and enabling rapid preparation while maintaining individualized formulation accuracy

AI summary
Computer systems and non-transitory computer readable media for determining an amount of an ingredient for a preparation for a requested therapy (e.g., an order or a prescription) includes an identifier, volume, and amounts of first and second compounds in each of a plurality of premix solutions. A predefined formulary comprising a formulary concentration of each of a plurality of additions is provided. A premix solution is selected. An amount of a first additions to be added to the premix solution may be selected. A number of bags of the premix solution, needed to satisfy a volume associated with the selected premix solution, are optionally reserved. An additive volume is determined at least by the specified first amounts of the first addition and a corresponding formulary concentration.
