Patient Image Registration Control With Walking Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for associating image data of affected areas with patient information in medical settings often result in registration operation errors, such as omission, erroneous recording, and misidentification, due to user oversight or GPS measurement inaccuracies.
Innovation Solution
An electric equipment with functions to acquire patient information, generate and store image data, and detect user walking information, which notifies the user and stops photographing when a change in patients is detected, ensuring accurate association of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually reads patient identifiers using a camera, then patient information can be acquired and stored, but registration operation errors such as omission, erroneous recording, and misidentification occur due to user oversight
Solution Approach 1:
The system automatically detects patient identifiers and manages patient information without requiring manual reading operations. The camera and control unit autonomously perform identifier recognition and patient information management, eliminating the need for users to manually read and record patient identifiers, thereby preventing registration errors while maintaining ease of use
Solution Approach 2:
The system provides visual feedback by displaying detected patient identifiers and information to the user, allowing confirmation and correction before final registration. This feedback mechanism ensures accurate patient information association while maintaining operational simplicity
2Extent of automation
If GPS information is used to detect patient changes, then automatic detection is enabled, but sufficient measurement accuracy cannot be ensured in indoor hospital environments
Solution Approach 1:
The patent replaces GPS-based position detection with an indoor positioning system that uses wireless signal strength measurements to detect user movement and patient changes. This substitution enables accurate automatic detection in indoor hospital environments where GPS is ineffective, maintaining both automation and measurement precision
Solution Approach 2:
The system uses wireless signal strength as an intermediary parameter to infer position changes and patient changes. Instead of directly measuring position like GPS, the system measures signal strength variations caused by user movement and translates these into patient change detections, achieving accurate indoor positioning and automatic detection
3Measurement precision
If the system continuously monitors user movement to detect patient changes, then accurate patient change detection is achieved, but false detections occur due to GPS measurement errors
Solution Approach 1:
The system dynamically adjusts its detection thresholds and parameters based on the indoor environment and signal characteristics. By making the detection criteria adaptive rather than fixed, the system can distinguish between genuine patient changes and false signals caused by environmental factors, maintaining both detection accuracy and system stability
Solution Approach 2:
The system performs preliminary calibration and baseline establishment before actual patient change detection. By pre-establishing normal signal variation patterns and detection thresholds specific to each indoor location, the system reduces false detections while maintaining sensitivity to real patient changes
Data Source
AI summary
An examination assisting apparatus capable of preventing an error in a registration operation performed by an user for associating photographed image data of an affected area of a patient with patient information. A user acquires patient information by reading a patient identifier and holds the same in a storage medium, and generates and stores photographed image data in association with the patient information stored in the storage medium. Walking information of a walk of the user is acquired. Notification to the user is performed based on the walking information. Photographing by an image capturing operation is stopped based on the walking information. The patient information is deleted from the storage medium based on an operation by the user in response to the notification. The notification is terminated in a case where the patient information is deleted from the storage medium.
