Drip Chamber Float Switching for Continuous Multi-Bottle Infusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infusion sets require manual monitoring of liquid levels in infusion bottles, leading to potential medical accidents due to incomplete infusion or air entry into the patient's bloodstream, especially when multiple bottles are used.
Innovation Solution
A drip component with a chamber and liquid on-off parts that automatically switch infusion bottles based on liquid levels, using a floating body to open or close channels for seamless infusion bottle changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual monitoring of liquid levels is used in existing infusion sets, then the structure is simple, but medical accidents occur due to incomplete infusion or air entry into the patient's bloodstream
Solution Approach 1:
The liquid level floating body automatically detects the liquid level in the infusion bottle and triggers the puncture device to switch between bottles without human intervention. The system serves itself by using the liquid's own level to activate the switching mechanism, eliminating the need for manual monitoring and preventing medical accidents.
Solution Approach 2:
The liquid level floating body provides continuous feedback on the liquid level in the infusion bottle. When the liquid level drops below a threshold, the floating body moves and triggers the puncture device to switch to the next bottle, creating a closed-loop feedback system that ensures reliable operation.
2Duration of action of moving object
If multiple infusion bottles are used, then the infusion duration is extended, but the complexity of manual switching increases and the risk of error increases
Solution Approach 1:
The system automatically manages multiple infusion bottles by using the liquid level floating body to detect when each bottle is depleted and autonomously triggering the puncture device to switch to the next bottle. This eliminates the burden of manual switching while extending infusion duration.
Solution Approach 2:
Multiple infusion bottles are prepared in advance and arranged in sequence. The puncture device is pre-configured to automatically switch between them based on liquid level detection, so that when one bottle is depleted, the next bottle is already ready for immediate connection without requiring manual intervention.
3Productivity
If the puncture device is manually switched between infusion bottles, then the device complexity is low, but the time required for switching increases and productivity decreases
Solution Approach 1:
The liquid level floating body and puncture device work together as an automatic system that eliminates manual switching operations. When the liquid level drops, the floating body automatically triggers the puncture device to disconnect from the current bottle and connect to the next one, saving significant time and improving infusion efficiency.
Solution Approach 2:
The manual mechanical operation of switching bottles is replaced by an automatic mechanical system consisting of the liquid level floating body that detects the level and triggers the puncture device. This substitution of manual mechanical operation with an automated mechanical system reduces switching time and improves productivity.
4Reliability
If the liquid level is not monitored timely, then the operation is simple, but air may enter the patient's bloodstream causing medical accidents
Solution Approach 1:
The liquid level floating body continuously self-monitors the liquid level in the infusion bottle and automatically triggers the switching mechanism when the level becomes critical. This self-monitoring system ensures patient safety without requiring external automation infrastructure.
Solution Approach 2:
The floating body provides continuous visual and mechanical feedback on the liquid level. When the liquid level drops below the safe threshold, the floating body moves to a position that triggers the puncture device to switch bottles, creating a reliable feedback mechanism that prevents air entry into the patient's bloodstream.
