Solution Overview

Problem

Endoscopes are difficult to decontaminate effectively, posing a risk of infection due to bioburden retention during reprocessing, especially when manual or automated methods are inefficient.

Innovation Solution

A reprocessing case with segmented shells and faceplates, integrated manifolds, and fluid delivery systems that facilitate automated disinfection and storage, ensuring thorough disinfection and containment of contaminants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual or automated reprocessing methods are used for endoscopes, then the reprocessing procedure can be performed, but the decontamination effectiveness is insufficient and bioburden retention occurs

Engineering Contradiction:
Improvedecontamination effectivenessVSAvoidbioburden retention
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The reprocessing case is divided into multiple segments including a first segment with a first shell and faceplate, and a second segment with a second shell and faceplate. These segments can be independently opened and closed to allow placement of the endoscope and subsequent sealing for disinfection. This segmentation enables thorough contact with disinfectant while maintaining containment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reprocessing case acts as an intermediary container between the endoscope and the external environment. It provides a controlled environment where disinfectant can be introduced and retained, ensuring effective decontamination while preventing bioburden escape during the reprocessing procedure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the reprocessing case uses a closed configuration for containment, then contaminants are contained, but access for disinfection application is limited

Engineering Contradiction:
Improvecontaminant containmentVSAvoiddisinfection access
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The reprocessing case transitions between different configurations - open configuration for loading and disinfection application, and closed configuration for containment. The first and second segments can be opened to allow disinfectant application, then closed to maintain containment. This dynamic reconfiguration resolves the contradiction between accessibility and containment.

Inventive Principle:
Principle #15Dynamics

3Extent of automation

If automated reprocessing systems are implemented, then labor assistance is provided, but the complexity of the system increases

Engineering Contradiction:
Improveautomated reprocessingVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The reprocessing case is designed to be compatible with automated reprocessors while maintaining a relatively simple structure. The case can be used in both manual and automated settings, performing multiple functions including containment, disinfection application, and sterilization. This multi-functionality reduces the need for additional specialized equipment, thereby limiting complexity increase despite automation integration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A reprocessing case may be used to assist in reprocessing an instrument, such as an endoscope in an automated reprocessor. The reprocessing case may include various features such that the case may include and be transitioned between a closed configuration, an open configuration, and a disinfection configuration. In particular the reprocessor may transition the case to a disinfection configuration during a reprocessing procedure.
