Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mode switching is used to adjust infusion parameters, then healthcare personnel can control the infusion device, but the operational efficiency is low and time-consuming
Solution Approach 1:
The infusion device automatically monitors physiological parameters and adjusts infusion parameters without requiring manual intervention from healthcare personnel. The system serves itself by detecting when parameters fall outside preset ranges and autonomously switching modes or adjusting settings, eliminating the time-consuming manual operation while preserving control capability.
Solution Approach 2:
The system continuously monitors physiological parameters and uses this feedback to automatically adjust infusion parameters. When the monitored parameters fall outside preset ranges, the system receives feedback and autonomously switches between operating modes or modifies infusion settings, creating a closed-loop control system that improves operational efficiency while maintaining control.
2Adaptability or versatility
If manual mode switching is implemented, then infusion parameters can be adjusted according to patient state, but the process takes a long time
Solution Approach 1:
The system pre-sets multiple operating modes with different infusion parameters before clinical use. When physiological parameters fall outside preset ranges, the system can immediately switch to the pre-configured appropriate mode without requiring time-consuming manual calculation or setup, enabling rapid adaptation to changing patient conditions.
Solution Approach 2:
The infusion device autonomously monitors physiological parameters and automatically switches between pre-configured operating modes based on real-time patient state, eliminating the time delay associated with manual mode switching while maintaining adaptability to patient conditions.
3Productivity
If automatic adjustment is implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The infusion device integrates multiple functions including physiological parameter monitoring, automatic parameter adjustment, and mode switching within a single system. By making the device universal and multi-functional, the automation capability is built-in rather than added as a separate complex system, thereby improving operational efficiency without proportionally increasing overall device complexity.

AI summary
The invention provides an infusion device, a control method and a computer-readable storage medium. A target object, such as a patient, is infused according to a set infusion parameter and a current first physiological parameter of the target object is determined. A target infusion parameter is then determined according to the target parameter when the first physiological parameter falls outside a preset range. The target object is infused according to the target infusion parameter. The target parameter includes the first physiological parameter, a weight of the target object and/or a constant infusion parameter. When the physiological parameters of the target object fall outside the preset range, the infusion device automatically adjusts the infusion parameters of the infusion device, without requiring the healthcare personnel to manually switch the operating mode of the infusion device for adjustment of the infusion parameters, thereby improving the efficiency of the infusion device.
