Medical Injection Control Device Internal Pressure Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical injection systems face challenges in detecting leaks in user-activated control devices, particularly during and after the application of external forces, which can lead to inaccurate fluid delivery and require manual inspection for leaks.
Innovation Solution
Incorporating a pressure sensor within the user-activated control device that monitors internal pressure changes, including drops below baseline pressure after the external force is released, to generate notifications for potential leaks, allowing for timely inspection and replacement or repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection for leaks is performed, then operators can detect leaks, but the process is time-consuming and requires system shutdown
Solution Approach 1:
The patent replaces manual visual inspection with an automated electronic pressure sensing system. The pressure sensor continuously monitors internal pressure of the control device and automatically generates leak notifications when pressure drops occur, eliminating the need for manual inspection and system shutdown.
Solution Approach 2:
The system performs self-diagnosis by automatically detecting pressure changes that indicate leaks. The control module continuously monitors pressure and autonomously generates notifications without requiring operator intervention, enabling the system to detect and report its own problems.
2Measurement precision
If continuous pressure monitoring is implemented, then leak detection sensitivity is improved, but device complexity increases
Solution Approach 1:
The pressure sensor serves multiple functions: it monitors internal pressure during operation, detects leaks by identifying pressure drops, and provides baseline pressure data for comparison. This multi-functionality achieves high measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The system implements continuous feedback by comparing real-time pressure readings against baseline pressure values. When pressure drops below the baseline, the control module automatically generates a leak notification, providing precise leak detection through simple comparative logic rather than complex analysis.
3Reliability
If pressure sensor monitoring continues after force release, then leaks are detected more reliably, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring by continuously sampling pressure and comparing it to baseline values. This periodic comparison approach maintains high detection reliability during the critical post-release period while consuming minimal energy, as the processor only performs simple threshold comparisons rather than continuous complex analysis.

AI summary
A control module for a medical injection system generates an injection control signal based on sensed internal pressure of a user activated control device, for example, in response to an applied external force that causes the sensed internal pressure to increase from a baseline pressure, and continues to sense the internal pressure of the device, following release of the applied external force, so that, if the sensed internal pressure drops below the baseline pressure, the control module may generate a notification. Thus, an operator of the system may monitor internal pressure of the control device for a drop below the baseline pressure, and then, if such a drop is detected, inspect the control device for leaks and reconnect, replace or repair the control device, or simply reconnect or replace the control device.
