Medical Instrument Container Venting for Uniform Liquid Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical instrument treatment devices fail to ensure optimal treatment liquid residence time within containers, leading to ineffective and non-homogeneous treatment of both rigid and flexible instruments.
Innovation Solution
A containing device with a calibrated discharge hole in the bottom and a mobile lid, along with air venting, to control liquid flow and maintain treatment liquid inside the container for extended periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If treatment liquid is circulated quickly through the container, then liquid flow rate is improved, but treatment effectiveness and homogeneity deteriorate
Solution Approach 1:
The system dynamically adjusts the balance between liquid flow rate and residence time by controlling the discharge hole size and position. The mobile lid can be positioned to optimize liquid levels, and the discharge hole calibration ensures that liquid flows fast enough for efficient treatment but slow enough to maintain adequate contact time with instruments for effective washing and sterilizing.
2Productivity
If treatment liquid flows too fast through the container, then processing speed is improved, but treatment homogeneity deteriorates
Solution Approach 1:
The discharge hole is strategically positioned and calibrated to create localized flow patterns that ensure uniform treatment distribution. The hole's specific location and size create turbulence and flow mixing zones that promote homogeneous treatment of all instrument surfaces while maintaining overall processing efficiency.
3Reliability
If the container is sealed tightly to maintain sterility, then protection is improved, but air venting capability deteriorates
Solution Approach 1:
The mobile lid acts as an intermediary element that can be positioned to simultaneously achieve hermetic sealing for sterility maintenance and controlled air venting when needed. The lid's mobility allows it to function as both a seal and a venting mechanism, with its position adjusted based on the specific treatment requirements and air pressure conditions within the container.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Guarantees effective washing and sterilizing of both rigid and flexible instruments by optimizing liquid permanence and preventing air bubble formation, ensuring thorough treatment.
Implementation Method 1
a discharge hole made in the bottom, calibrated so as to allow a discharge of liquid with a flow rate lower than the flow rate loaded through the inlet
Implementation Method 2
a lid mobile with respect to the container to selectively define a closed condition and an open condition of the containing device
Implementation Method 3
The lid comprises at least one hole for air to escape
