Animatronic Eye Simulator for Ocular Disease Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient simulators fail to provide realistic medical training due to inadequate representation of eye movements and diseases such as nystagmus, blepharospasm, and ptosis, lacking lifelike appearance and responsiveness to user stimuli.
Innovation Solution
An interactive educational system featuring animatronic eyes with infrared sensors and transmitters, and a microprocessor that simulates eye movements and diseases by tracking objects and adjusting pupil size and eyelid movement to mimic human eye behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If textbooks and flashcards are used for training, then students can learn patient care protocols, but hands-on practice capability is not provided
Solution Approach 1:
The patent creates a realistic copy of human eyes with animatronic features that replicate actual eye movements, diseases, and responses to stimuli. This allows students to practice hands-on procedures on a lifelike model without risking harm to real patients, thereby providing both information delivery and practical training capability.
Solution Approach 2:
The eye assembly serves as an intermediary between theoretical training materials and real patient interaction. It provides a safe intermediate environment where students can develop practical skills through hands-on practice before working with actual patients, bridging the gap between textbook learning and clinical application.
2Ease of operation
If actual patients are used for hands-on practice, then practical training is provided, but patient safety is compromised
Solution Approach 1:
By creating a realistic copy of human eyes that replicates actual physiological responses and disease manifestations, the patent enables safe hands-on practice. Students can interact with the animatronic model without any risk to real patients, while still gaining practical experience in eye examination and disease identification.
Solution Approach 2:
The patent converts the potential harm of inexperienced students practicing on real patients into a benefit by creating a safe training environment. The animatronic eye assembly allows unlimited practice opportunities without compromising patient safety, transforming what would be a harmful situation into a beneficial training solution.
3Ease of operation
If existing simulators are used, then some training functionality is provided, but realistic representation of eye movements and diseases is lacking
Solution Approach 1:
The patent implements dynamic animatronic features that replicate realistic eye movements, including saccades, pursuits, and disease-specific movements like nystagmus. The eyelids and pupils respond naturally to stimuli, providing authentic training experiences that static or simplified simulators cannot deliver, thereby improving both functionality and realism.
Solution Approach 2:
The patent utilizes parameter changes in the animatronic system to accurately represent various eye conditions and responses. By dynamically adjusting parameters such as pupil size, eyelid position, and movement patterns, the simulator can realistically depict different diseases and physiological states, enhancing training accuracy without compromising functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system offers a realistic and diagnostic simulation of eye conditions, enhancing medical training by providing a lifelike and responsive patient simulator that accurately replicates eye movements and diseases, improving training effectiveness.
Implementation Method 1
at least one infrared (IR) transmitter to transmit IR radiation towards an object placed in front of the eye assembly, at least one IR sensor to receive an IR response signal reflected off the object
Data Source
AI summary
An apparatus and method of controlling an eye assembly of a patient simulator. The method generally includes receiving, via a data input device, one or more inputs, transmitting the one or more inputs to a controller in communication with the data input device, and controlling, using the controller and based on the one or more inputs, the eye assembly of the patient simulator to simulate ocular disease, which ocular disease includes nystagmus, blepharospasm, ptosis, idling, or a combination of two or more thereof.
