Infusion Module Adapter for Cross-Generation Pump Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infusion pump systems require complete system upgrades when individual modules need updating, leading to a trade-off between cost-optimization and feature-optimization, as upgrading individual modules is cost-prohibitive and delays access to improved efficiency and safety features.
Innovation Solution
An infusion module adapter system that includes a first interconnect system with mechanical and logical connectors, power conversion circuitry, and communication processing circuitry to couple incompatible subsystems, allowing individual module upgrades while maintaining cross-compatibility and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual modules are upgraded, then feature-optimization is improved, but cost-optimization deteriorates due to system compatibility requirements
Solution Approach 1:
An adapter module is introduced as an intermediary component between the control unit and the infusion pump. This adapter contains conversion circuitry that translates communication protocols and power specifications between incompatible systems, enabling individual module upgrades without requiring complete system replacement. The adapter acts as a bridge that resolves compatibility issues between older pumps and newer control units.
Solution Approach 2:
The infusion pump system is divided into separate functional modules (control unit, pump module, adapter) that can be independently upgraded. The adapter module specifically segments the compatibility function from the core system components, allowing individual modules to be updated without affecting the entire system. This modular approach enables selective upgrading of only the necessary components.
2Reliability
If the entire system is upgraded, then cross-compatibility is improved, but cost-optimization deteriorates due to complete system replacement
Solution Approach 1:
The adapter serves as a mediator that enables compatibility between mixed-generation components. Instead of replacing all components to achieve compatibility, the adapter allows older pumps to work with newer control units by translating interfaces and protocols. This reduces the quantity of components that need replacement while maintaining system reliability.
Solution Approach 2:
The adapter is designed with universal compatibility to work with multiple generations of infusion pumps and control units. It provides multi-functional capability by supporting both older and newer communication protocols and power specifications, allowing the system to maintain cross-compatibility without requiring complete system replacement.
3Adaptability or versatility
If individual modules are upgraded, then access to new features is improved, but time-optimization deteriorates due to delayed system-wide upgrades
Solution Approach 1:
The system is segmented into independently upgradable modules, allowing immediate access to new features in upgraded components without waiting for system-wide replacement. The adapter module specifically enables this by bridging compatibility gaps between different generation components, eliminating the time loss associated with coordinated system upgrades.

AI summary
An infusion module adapter system couples a control unit of a patient care system to an infusion pump. The adapter system includes a first interconnect system on a first side and a second interconnect system on a second side. The first interconnect system includes a mechanical connector having first support contacts for mechanical coupling to the control unit; and a logical connector having first power contacts and first communication contacts for logical coupling to the control unit. The second interconnect system includes an integrated connector having second support contacts, second power contacts, and second communication contacts for mechanical coupling and logical coupling to the infusion pump. The adapter system further includes power conversion circuitry configured to convert a power signal between the first power contacts and the second power contacts, and processing circuitry configured to convert messages between the first communication contacts and the second communication contacts.
