Self-Catheterization Training Model for Wheelchair-Level Practice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anatomical models for self-catheterization training are costly, bulky, and incapable of approximating the experience of performing ISC skills at the wheelchair level, failing to meet the needs of patients and caregivers who require training in seated positions.
Innovation Solution
A customizable self-catheterization training system with interchangeable anatomical models for male and female genitalia, attachable to various bases (wheelchair, tabletop, bed) for adjustable positioning and comfort, allowing practice in seated or prone positions, and featuring rotatable and height-adjustable designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing anatomical models are used for self-catheterization training, then training functionality is provided, but the models are costly and bulky
Solution Approach 1:
The training system is divided into separate components: a base portion that can be mounted to different surfaces (wheelchair, table, bed) and an anatomical model portion that attaches to the base. This segmentation allows the anatomical model to be smaller and less bulky while maintaining training functionality, and enables the base to be separately optimized for different mounting locations.
Solution Approach 2:
The base portion is designed with universal mounting capabilities that allow it to be attached to wheelchairs, tables, or beds using different mounting mechanisms. This multi-functionality reduces the need for multiple specialized models, decreasing overall cost and bulk while maintaining reliable training functionality across different user scenarios.
2Reliability
If table-based anatomical models are used for training, then training capability is provided, but the models cannot approximate the wheelchair level experience
Solution Approach 1:
The system allows dynamic reconfiguration by attaching the anatomical model to different base mounting locations. When mounted on a wheelchair, the model positioned between the user's legs approximates the actual self-catheterization experience at wheelchair level, providing position accuracy that matches the user's real-world training needs.
Solution Approach 2:
The base portion serves as an intermediary between the anatomical model and the mounting surface (wheelchair, table, or bed). This intermediary enables the model to be positioned at the appropriate height and orientation for each mounting location, allowing accurate approximation of the wheelchair-level experience when mounted on a wheelchair.
3Reliability
If existing models are designed for healthcare providers, then provider training is enabled, but patient self-training is not supported
Solution Approach 1:
The system is designed with universal applicability for both healthcare providers and patients. The anatomical model maintains anatomical accuracy for provider training, while the removable base mounting allows patients to attach it to their wheelchair for self-training. This multi-functionality enables the same model to serve both provider and patient training needs effectively.

AI summary
A self-catheterization training system includes an anatomical model that can be removably attached to one or more base styles to accommodate training for both patients and their caregivers at wheelchair level, bedside or on a tabletop. In a method of self-catheterization training, the self-catheterization training system is provided, and the catheter is inserted into an anterior opening and is passed through the passage to a posterior opening.
