Nasal Washing Assembly with Shape Recognition for Pediatric Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pediatric patients often refuse or become scared during nasal washing due to the discomfort and inability to remain calm, making it challenging to administer therapeutic agents effectively as mucus obstructs their entry into nasal areas.
Innovation Solution
A nasal washing assembly comprising a device with a specific shape and an electronic device with an embedded camera and display screen that recognizes the device in real-time, automatically displaying predetermined video content, such as cartoons or augmented reality, to distract and calm the patient during the procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nasal washing device is applied to pediatric patients, then nasal cleaning effectiveness is improved, but patient acceptance and cooperation deteriorate due to fear and inability to remain calm
Solution Approach 1:
An electronic device with camera and display screen serves as an intermediary between the nasal washing device and pediatric patient. The device captures images of the nasal washing device and displays predetermined video content (cartoons, games, or augmented reality content) to distract and calm the patient, thereby improving patient acceptance without compromising cleaning effectiveness
Solution Approach 2:
The system changes the visual content displayed to the patient based on recognition of the nasal washing device. When the camera detects the nasal washing device, the system automatically displays appropriate video content, transforming the patient experience from frightening to entertaining, thus improving cooperation
2Measurement precision
If tag or barcode is used for device recognition, then device identification accuracy is improved, but manufacturing complexity and orientation requirements worsen
Solution Approach 1:
The invention extracts the recognition target from specific features (tags, barcodes, logos) and uses the overall shape of the nasal washing device itself as the recognition target. This eliminates the need to attach additional components to the device, simplifying manufacturing while maintaining recognition accuracy through shape-based image processing
Solution Approach 2:
The system creates a digital copy or representation of the nasal washing device's shape through image capture and processing. By comparing the captured image with stored reference patterns of the device shape, the system achieves accurate identification without physical tags or barcodes
