Infusion Module Adapter for Cross-Compatible Pump Upgrades
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 mechanical and logical connectors, power conversion circuitry, and communication processing to enable compatibility and interoperation between otherwise incompatible subsystems, allowing for modular upgrades of infusion pump systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual modules are upgraded, then access to new features and improved efficiency is achieved, but system compatibility and cross-module integration are compromised
Solution Approach 1:
An adapter module is introduced as an intermediary component between the control unit and the infusion pump. The adapter includes a first interconnect system that couples to the control unit and a second interconnect system that couples to the infusion pump, enabling compatibility between modules with different interconnect standards. This allows individual module upgrades while maintaining system-wide integration.
2Reliability
If the entire system is upgraded, then cross-compatibility and system integration are maintained, but cost increases significantly
Solution Approach 1:
The interconnect system is segmented into separate functional components: a first interconnect system for coupling to the control unit and a second interconnect system for coupling to the infusion pump. This segmentation allows the adapter to bridge compatibility gaps between modules with different interconnect standards, enabling selective upgrading of individual modules rather than requiring complete system replacement.
3Productivity
If individual modules are upgraded, then feature optimization is achieved, but the frequency and scope of system upgrades are limited
Solution Approach 1:
The adapter module serves as a compatibility intermediary that enables immediate integration of upgraded modules with existing system components. By providing the necessary interface translation and signal compatibility, the adapter eliminates delays associated with waiting for complete system replacements, allowing facilities to immediately benefit from new features in upgraded modules.

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.
