Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulin pumps lack effective control over bolus infusion, particularly during periods of increased blood glucose levels after meals, necessitating a more reasonable and controlled delivery of insulin doses.
Innovation Solution
An insulin pump infusion control method that includes a control module to manage bolus infusion mode, utilizing reminder tones of different frequencies to confirm operations, and allowing for simple and quick adjustments through the bolus key, ensuring proper initiation and termination of bolus infusion based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional continuous dosage infusion is used, then the insulin pump can maintain basic blood glucose stability, but it cannot meet the increased insulin demand after meals
Solution Approach 1:
The patent implements dynamic infusion control by introducing two distinct infusion modes: continuous dosage infusion for baseline maintenance and bolus infusion for post-meal glucose spikes. The system dynamically switches between modes based on user needs and blood glucose conditions, allowing the insulin delivery rate to adapt flexibly to varying physiological states while maintaining reliable glucose control.
2Adaptability or versatility
If bolus infusion control is added to meet post-meal insulin demand, then the system becomes more complex
Solution Approach 1:
The control module serves multiple functions: it manages both continuous dosage infusion and bolus infusion, processes different types of user inputs (manual bolus requests, blood glucose data), and coordinates with the infusion pump mechanism. By designing a universal control module that handles diverse operations through a unified interface, the patent adds bolus infusion capability without proportionally increasing overall system complexity.
Solution Approach 2:
The system controls bolus infusion by adjusting key parameters: infusion rate, infusion duration, and total bolus dose. The control module calculates and sets these parameters based on user input and blood glucose data, enabling flexible bolus delivery without requiring complex hardware changes. This parameter-based control approach maintains system simplicity while achieving versatile infusion management.
3Ease of operation
If manual bolus key operations are required for dosage adjustment, then the operation process becomes more time-consuming
Solution Approach 1:
The system performs preliminary calculations of the required bolus dose based on blood glucose data and user input before initiating infusion. The control module pre-determines the optimal infusion parameters (rate, duration, total dose) based on the glucose elevation level, so that when the user confirms the bolus request, the infusion can start immediately with pre-calculated settings, minimizing the time from decision to execution.
Solution Approach 2:
The system incorporates feedback mechanisms where the control module provides real-time information to the user during bolus infusion setup, displaying calculated doses and infusion parameters for confirmation. This feedback loop allows users to verify and adjust settings quickly, reducing errors and enabling rapid confirmation of the bolus infusion parameters, thus minimizing operational time while maintaining safety.

AI summary
An insulin pump bolus infusion control method. A control module of a pump body controls the pump body to start a bolus infusion control mode after receiving a function starting signal; in the bolus infusion control mode, a bolus key of a control terminal or a bolus key of an insulin pump body sends an infusion dosage signal to the control module by means of one or more operations; if the control module receives a confirmation signal within a predetermined period of time, then the control module controls the pump body to start bolus infusion; and if the control module receives a cancellation signal or does not receive the confirmation signal within a predetermined period of time, then the control module controls the pump body to exit the bolus infusion mode. Using the method enables an insulin pump to execute a more reasonable control when carrying out the bolus infusion, i.e., starting, setting and implementation of the bolus infusion, and enables a simple and quick operation.
