Patient Simulator Facial Feature Dynamics for Medical Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient simulators lack realism in simulating human-like features and responses, failing to provide adequate training for medical professionals due to inadequate representation of symptoms and lack of lifelike appearance and functionality.
Innovation Solution
An interactive education system with a patient simulator that includes advanced features such as realistic eye, neck, brow, and mouth movement, tear duct activation, and a processing module to simulate various medical scenarios, allowing for team-based training and real-time assessment in a lifelike environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing physical simulators are used for patient care training, then hands-on practice can be provided without risking actual patients, but the simulators fail to exhibit accurate symptoms and respond appropriately to student stimuli, lacking realism
Solution Approach 1:
The patent applies dynamics by implementing movable facial features (eyes, brows, mouth, neck) that can change position and expression in response to simulated physiological conditions. The eyes can move vertically and horizontally, brows can raise and lower, the mouth can open and close, and the neck can rotate, allowing the manikin to dynamically respond to medical scenarios rather than remaining static
Solution Approach 2:
The patent applies copying by creating a lifelike replica of human facial features and physiological responses. The manikin copies actual human anatomical structures and their behavioral patterns during medical conditions, such as eye movement patterns, facial expressions, and neck positioning that occur in real patients, providing authentic training experiences
2Ease of operation
If existing simulators are used, then training can be conducted without patient risk, but they fail to look and feel lifelike, which fails to improve the training process
Solution Approach 1:
The patent applies segmentation by dividing the facial features into independent movable components - eyes, brows, mouth, and neck - each capable of autonomous movement and expression. This segmentation allows each feature to be controlled independently to create realistic facial expressions and responses to various medical scenarios
Solution Approach 2:
The patent applies parameter changes by varying the position, orientation, and expression parameters of facial features based on simulated physiological conditions. The system changes parameters such as eye position (vertical and horizontal), brow elevation, mouth opening degree, and neck rotation angle to reflect different medical states and responses to student actions

AI summary
A method, apparatus, and system according to which a patient simulator includes one or more of the following: a left eye assembly including a simulated left pupil, a simulated left eyelid, and/or a simulated left iris; a right eye assembly including a simulated right pupil, a simulated right eyelid, and/or a simulated right iris; a neck assembly including a simulated neck; a left brow assembly including a simulated left brow; a right brow assembly including a simulated right brow; a tear duct assembly including simulated left and right cheeks through which artificial pores are formed; and a mouth assembly including a simulated mouth. In various embodiments, any one, or a combination, of these assemblies may be, include, or be part of, a manikin in the form of a human face, and may therefore be activated simultaneously to realistically simulate life-like human emotional states.
