Endoscope Cleaning Valve Indicators for Reliable Valve Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning valves for medical devices, such as endoscopes, are often confused with procedural valves, leading to potential incorrect use during procedures and increased reprocessing costs due to the need for separate cleaning and differentiation is not adequately addressed.
Innovation Solution
The development of medical cleaning valves with distinct indicators, such as raised surfaces, tactile differences, and color contrasts, along with removable indicators, to differentiate them from procedural valves, ensuring correct usage and reducing the risk of confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cleaning valves are designed with standard indicators, then manufacturing cost is reduced, but differentiation from procedural valves is insufficient leading to confusion and incorrect use
Solution Approach 1:
The patent applies color changes by providing the interface member with a colored proximal surface that is visually distinct from procedural valves. This color coding system allows for immediate visual differentiation, reducing the risk of incorrect valve selection while maintaining simple manufacturing processes through standard coloring techniques.
Solution Approach 2:
The patent applies local quality by providing tactilely distinct features at specific locations on the interface member, such as raised surfaces or textured areas on the proximal surface. These localized tactile indicators allow users to differentiate cleaning valves from procedural valves through touch alone, enhancing reliability without requiring complex indicator systems throughout the entire valve structure.
2Reliability
If multiple differentiation features are added to the cleaning valve, then confusion with procedural valves is reduced, but manufacturing complexity and cost increase
Solution Approach 1:
The patent implements color changes as a primary differentiation feature that can be applied through standard manufacturing coloring processes. This provides effective visual differentiation while maintaining ease of manufacture, as coloring is a routine operation in valve production that does not significantly increase complexity or cost.
Solution Approach 2:
The patent uses local quality by incorporating tactilely distinct features at specific locations on the interface member rather than modifying the entire valve structure. These localized features such as raised surfaces or textured areas provide effective differentiation while requiring minimal additional manufacturing steps, thus maintaining ease of manufacture.
3Reliability
If tactile indicators are added to the interface member, then differentiation is enhanced for tactile users, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by providing tactilely distinct features at specific locations on the interface member. These localized tactile features such as raised surfaces or textured areas can be manufactured with standard precision techniques, as they only require differentiation at specific spots rather than throughout the entire component, thus avoiding excessive manufacturing precision requirements.

AI summary
A medical cleaning valve (or cleaning valve) may be configured to provide cleaning functionality to air and water channels of an endoscope. One or more embodiments described herein may include cleaning valves with features and/or components that facilitate differentiating them from procedural valves. In some embodiments, valves may be made from a limited number of parts and materials, to limit their cost. For example, multiple seals may be formed as a single component, such as via overmolding. In another example, wiper seals may be used to accommodate greater manufacturing tolerances. In yet another example, the valve may have a single elastomeric component, or spring cap, which may combine the functionality of a number of components (e.g., a boot, spring, spring housing, and stem cap).
