Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reprocessing methods for medical instruments with internal channels are inefficient in using compressed air, leading to unnecessary waste and increased operating costs due to unoptimized fluid connection management.
Innovation Solution
A method and system that identifies the type of medical instrument through a machine-readable identifier, controlling compressed air application only to occupied fluid connections during rinsing steps, and using shorter bursts for unused ports to minimize carryover and optimize air usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed air is applied to all fluid connections during rinsing steps, then fluid carryover is minimized, but compressed air consumption increases
Solution Approach 1:
The system applies compressed air selectively only to fluid connections that are actually occupied by the medical instrument, rather than applying air to all connections uniformly. The control unit identifies occupied connections based on instrument type and applies air only where needed, reducing waste while maintaining effectiveness in preventing fluid carryover.
Solution Approach 2:
The system divides the reprocessing chamber into multiple fluid connection zones and manages them independently. By segmenting the air application to specific occupied connections rather than treating all connections uniformly, the system optimizes compressed air usage while ensuring thorough rinsing of each occupied channel.
2Reliability
If compressed air bursts are applied between all rinsing steps, then reprocessing fluid carryover is reduced, but operating costs increase
Solution Approach 1:
The system changes the parameter of compressed air application from continuous or universal to selective and intermittent. By controlling the duration and targeting of air bursts based on actual instrument occupancy, the system reduces energy consumption while maintaining effective separation between rinsing steps.
Solution Approach 2:
The system implements periodic compressed air bursts at specific intervals between rinsing steps rather than continuous application. The control unit timing the air bursts to coincide with transitions between rinsing steps, creating periodic action that effectively prevents fluid carryover while minimizing overall air consumption.
3Reliability
If all fluid connections are treated with compressed air, then system cleanliness is maintained, but resource efficiency decreases
Solution Approach 1:
The system uses the medical instrument itself to determine which connections require compressed air treatment. The instrument's presence and type automatically identify occupied connections, allowing the system to serve itself by automatically targeting air application to the correct connections without manual intervention or resource waste.
Solution Approach 2:
The control unit receives feedback about the medical instrument type and connection occupancy, then adjusts compressed air application accordingly. This feedback mechanism ensures that air is applied only where needed, maintaining system cleanliness while improving resource efficiency through precise control based on actual usage patterns.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces compressed air consumption and operating costs by ensuring only necessary air is used, minimizing fluid carryover and maintaining a clean system for subsequent processes.
Implementation Method 1
the control unit controls the compressed air unit in such a way that it applies a burst of compressed air to the occupied fluid connection, so that reprocessing fluid present in the rinsed internal channel of the medical instrument is blown out of the channel
