Modular Anatomical Head and Neck Simulator for Emergency Procedure Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical professionals, especially those outside simulation centers, lack access to affordable and easy-to-use simulators for maintaining procedural skills in rare emergency medicine procedures due to high costs and limited availability of current simulators.
Innovation Solution
A low-cost, portable medical simulator apparatus that simulates the human head and neck, allowing for the practice of procedures like lateral canthotomy, cricothyrotomy, and esophagogastric balloon placement, with modular components such as a cricothyroid model, eye model, and esophagus model that can be used separately or together to simulate real-life conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current simulators are used for procedural training, then training fidelity is improved, but cost and accessibility worsen
Solution Approach 1:
The simulator is divided into modular components including a head model, neck model, eye model, and cricothyroid model that can be assembled and disassembled independently. This segmentation allows for simplified manufacturing of individual components while maintaining overall training fidelity when assembled together.
Solution Approach 2:
The invention creates simplified anatomical copies using materials like silicone rubber and foam that replicate the essential physical properties and anatomical relationships of human head and neck structures without requiring expensive, highly realistic replicas. The models capture critical procedural features while reducing manufacturing complexity and cost.
2Reliability
If simulation center resources are accessed, then procedural skill maintenance is improved, but accessibility and convenience worsen
Solution Approach 1:
The simulator is designed with flexible mounting options including adhesive backing and magnetic components that allow it to be easily positioned on various surfaces such as refrigerators, walls, or portable stands. This dynamic adaptability enables practitioners to use the simulator in diverse locations including homes, clinics, and mobile settings without requiring fixed simulation center infrastructure.
Solution Approach 2:
The simulator is designed for independent use by individual practitioners without requiring supervision, equipment, or resources from a simulation center. The self-contained nature of the model allows clinicians to autonomously maintain procedural skills in their own practice environments.
3Manufacturing precision
If high-fidelity simulators are used, then procedural accuracy is improved, but device complexity and cost worsen
Solution Approach 1:
The simulator concentrates manufacturing precision and anatomical detail only in the specific regions where procedural accuracy is critical, such as the cricothyroid membrane area and eye structure, while using simpler materials and construction methods for surrounding areas. This localized approach maintains procedural accuracy where needed without unnecessarily increasing overall device complexity.
Solution Approach 2:
The simulator uses material property changes rather than complex structural designs to achieve procedural accuracy. For example, silicone rubber provides realistic tissue compliance and cutting characteristics without requiring intricate internal structures, and foam materials replicate anatomical shapes and densities at lower complexity levels.

AI summary
A simulator apparatus for training medical professionals in various procedures involving the head, eye, larynx, and esophagus. The apparatus includes a head and neck model, an eye model, a cricothyroid model, and an esophagus model. The head and neck model is designed to be removably attached to the eye model, cricothyroid model, and esophagus model. The head and neck model simulates the human head, the eye model simulates the human eye, the cricothyroid model simulates the human larynx thyroid, and cricothyroid cartilage, and the esophagus model simulates the human esophagus. For training purposes, the models may be used individually without accompaniment of the other models, or in conjunction with one or more of the other models. The purpose of the simulator is to provide a user with a cost-effective, portable training simulator to practice performing procedures involving the human head, eye, larynx and cricothyroid muscle, and esophagus.
