Portable Memory Programming for Error-Resistant Infusion Pumps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infusion pumps require manual programming by users or healthcare professionals, leading to increased complexity, potential errors, and higher manufacturing and distribution costs, especially for pre-set infusion pumps.
Innovation Solution
A portable memory device that automatically programs infusion devices with predefined infusion rates and provides confirmation of proper programming, using contact or proximity-based data transmission, and includes features to prevent manual adjustment or reprogramming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual programming is used for infusion pumps, then users can program custom infusion rates, but device complexity and potential for programming errors increase
Solution Approach 1:
The patent uses portable memory devices that contain pre-programmed infusion rate information as copies of the programming data. Instead of requiring users to manually program complex parameters, the system transfers pre-validated programming information from these memory devices to the infusion pump, simplifying the user interface while maintaining programming capability.
Solution Approach 2:
The programming information is prepared and validated in advance on the portable memory devices before use. The infusion pump receives this pre-programmed data, which includes predetermined infusion rates and parameters that have been verified beforehand, eliminating the need for complex real-time programming by the user.
2Ease of operation
If pre-set infusion pumps with multiple unique programs are manufactured, then patient simplicity is maintained, but manufacturing and distribution complexity increase
Solution Approach 1:
The patent employs a universal portable memory device format that can store different infusion rate programs and be used with a single type of infusion pump. Instead of manufacturing multiple unique pump models for different infusion rates, the system uses one pump design that can receive various pre-programmed memory devices, simplifying manufacturing while maintaining program diversity.
Solution Approach 2:
The programming functionality is segmented into separate portable memory devices rather than being integrated into the pump itself. This allows the pump to remain simple and generic while the programming information is stored externally in interchangeable memory cartridges that can be easily exchanged.
3Reliability
If automatic programming is implemented, then programming errors are reduced, but device complexity increases
Solution Approach 1:
The portable memory device serves as an intermediary between the programming source and the infusion pump. It contains the programming information in a standardized format and transfers it automatically to the pump through a simple interface, reducing the complexity of the pump's programming system while ensuring accurate and reliable programming.
Solution Approach 2:
The manual mechanical process of programming through buttons and menus is replaced with an automated electronic data transfer system. The portable memory device uses electronic communication to automatically transmit programming information to the pump, eliminating manual entry errors and simplifying the user interaction.
Data Source
AI summary
A portable memory device for use with an infusion device, the portable memory device comprising a memory including information that, when received by the infusion device, causes the infusion device to set a predefined infusion rate; and output a confirmation that the infusion device has been properly programmed with the predefined infusion rate; wherein the portable memory device is configured to automatically transmit the information to the infusion device in response to the portable memory device being brought into a transmitting position with respect to the infusion device.
