Compact Catheterization Trainer with Interchangeable Genitalia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current urinary catheterization training devices are often large, heavy, and bulky, making them difficult to store and access in clinical settings, which can lead to improper performance of catheterization procedures and increased risk of Catheter-Associated Urinary Tract Infections (CAUTIs, as healthcare providers lack frequent and convenient training opportunities for both male and female patients.
Innovation Solution
A compact, lightweight, and portable catheterization training device that includes a rigid housing with a storable leg and torso model, urinary bladder, and interchangeable male and female genitalia accessories, allowing for realistic practice of the entire catheterization procedure from preparation to cleanup, and is designed for easy storage and immediate access in clinical settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional large-scale body models are used for catheterization training, then training realism is improved, but device portability and storage ease deteriorate
Solution Approach 1:
The training device is divided into separable components: a torso model with internal anatomy, interchangeable genitalia accessories for male and female patients, and a storage container. This segmentation allows the realistic training components to be stored compactly when not in use, resolving the contradiction between training realism and portability.
Solution Approach 2:
The genitalia accessories are designed to nest within or attach to the torso model, and the entire assembly stores within a compact container. This nested arrangement maintains realistic training capabilities while minimizing storage space, addressing the portability issue without sacrificing training fidelity.
2Volume of stationary object
If traditional centralized storage of training devices is implemented, then storage space efficiency is improved, but access convenience deteriorates
Solution Approach 1:
By making the training device self-contained and portable, each clinical unit can have its own training device rather than relying on centralized storage. This eliminates travel time to centralized storage locations while the compact design maintains space efficiency.
Solution Approach 2:
The device is designed to be independently portable and functional at the point of care, eliminating the need for centralized storage and retrieval operations. Clinicians can access training immediately at the clinical location without leaving the workspace.
3Adaptability or versatility
If comprehensive anatomy models are used for full procedure training, then training completeness is improved, but device complexity increases
Solution Approach 1:
The comprehensive anatomy is achieved through modular components: a basic torso model with internal bladder and urethra, plus interchangeable genitalia accessories. This segmentation provides complete training capability for both male and female procedures while keeping each individual component relatively simple.
Solution Approach 2:
The torso model serves multiple functions: it provides the internal anatomy for all procedures, accepts different genitalia accessories for male/female training, and includes storage for training materials. This multi-functionality achieves comprehensive training without proportionally increasing complexity.

AI summary
A catheterization training device includes a rigid housing defining an internal cavity, and a leg/torso body model constructed of lightweight material and storable within the internal cavity. The body model houses a urinary bladder model housed and a proximal urethra model defining a first canal in fluid communication with said urinary bladder model and terminating in a connector. The device further includes at least one genitalia accessory having a configuration of one of human male and human female genitalia. Each genitalia accessory defines a distal urethral model comprising a second canal terminating in a corresponding connector operable to form a mechanical interconnection with the connector of the body model to form a fluid-tight interconnection therewith, and a continuous canal through the distal urethra model and the proximal urethra model and into the urinary bladder model.
