Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nasopharyngeal airway (NPA) training devices are bulky, cumbersome, and not portable, making them unsuitable for home or field training, and they lack the ability to provide cross-training in other medical procedures like needle insertions.
Innovation Solution
A modular NPA training adjunct that can be used with existing self-contained needle insertion training platforms, allowing for portable and versatile training that includes NPA procedures, designed to be lightweight, durable, and adaptable for use in various settings, including classrooms and field conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional NPA training devices are used to provide anatomical correctness and training functionality, then training effectiveness is improved, but device portability and ease of use deteriorate due to bulky size and support requirements
Solution Approach 1:
The training device is divided into separate modular components: a head assembly containing anatomical features, a body assembly with training mechanisms, and optional support components. This segmentation allows the anatomical training features to be separated from bulky support systems, enabling portable training while maintaining effectiveness.
Solution Approach 2:
The essential NPA training functionality is extracted from the traditional bulky trainer system. The critical anatomical features and insertion training capabilities are isolated into a compact, portable device, removing unnecessary bulk while preserving core training effectiveness.
2Adaptability or versatility
If traditional NPA training devices are designed for classroom settings with support components, then training functionality is improved, but device complexity and durability worsen due to multiple linked components
Solution Approach 1:
The training device is designed to perform multiple training functions including NPA insertion, needle insertion, and other medical procedures through modular attachments. This multi-functionality replaces the need for multiple separate devices, reducing overall system complexity while expanding training capabilities.
Solution Approach 2:
The device incorporates adjustable and reconfigurable components that can be dynamically modified for different training scenarios. The modular design allows components to be added, removed, or reconfigured based on specific training needs, providing adaptability without permanent complexity.
3Measurement precision
If traditional NPA trainers are designed as stand-alone devices, then NPA training specificity is improved, but cross-training capability for other medical procedures deteriorates
Solution Approach 1:
The device maintains specialized NPA training capabilities through dedicated anatomical features while incorporating universal interfaces and modular components that enable other medical procedures such as needle insertion and cricothyrotomy training, achieving both specificity and versatility.
Solution Approach 2:
The training device uses separable modular components where the core anatomical model remains for NPA training while interchangeable attachments provide specialized functionality for different procedures, maintaining training specificity for each procedure while enabling cross-training.

AI summary
A modular Nasopharyngeal Airway Insertion training adjunct for a medical training device having an orifice that opens into an inner cavity. The adjunct includes a base that releasably attaches to the medical training device, and a simulated nasal anterior aspect affixed to the base. Two nasal orifices extend into an inner chamber of the aspect. The inner chamber opens into an orifice in the base. The base orifice aligns with the medical training device orifice when the base is properly attached to the medical training device, so as to enable Nasopharyngeal Airway Insertion training there through.
