Medical Exam Order Control for Input Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical examination systems face difficulties in determining whether to prioritize user-input examination orders or those received from upstream systems, leading to potential input collisions and increased user complexity in managing switching operations.
Innovation Solution
A medical examination system with a receiving unit for patient identification, an operation unit for inputting patient information, and a processing unit that displays objects for examination processing only if patient information is input by the user, while avoiding automatic execution of imaging mode when patient information is not manually input, thereby providing user confirmation options through OK and CANCEL buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system automatically executes imaging mode when receiving examination orders from upstream systems, then productivity is improved, but input collisions occur and reliability deteriorates
Solution Approach 1:
The system performs preliminary detection to check whether patient information has been manually input by the user before automatically executing imaging mode. This preliminary action prevents input collisions by identifying the state of manual input before the automatic execution occurs, ensuring that automatic imaging only proceeds when appropriate.
2Reliability
If the system requires manual switching operations to select between user-input and upstream system examination orders, then reliability is improved, but device complexity increases
Solution Approach 1:
The system automatically determines whether to execute imaging based on detecting whether patient information has been manually input, without requiring users to perform manual switching operations. The system serves itself by autonomously resolving the selection between user-input and upstream system orders through detection of manual input state, thereby simplifying the interface while maintaining reliability.
3Ease of operation
If the system displays objects for examination processing for all received orders, then ease of operation is improved, but loss of information increases due to user confusion
Solution Approach 1:
The system selectively displays objects for examination processing only when patient information has been manually input by the user, rather than displaying for all received orders. This partial action approach prevents user confusion by showing only relevant items while still maintaining ease of operation for the intended use case.
Data Source
AI summary
A medical examination system causes a display unit to display an object for shifting to examination processing together with patient information corresponding to identification information of a patient received by a receiving unit if the patient information of the patient is input via an operation unit when the receiving unit receives the identification information of the patient from an external device. The medical examination system shifts to the examination processing without causing the display unit to display the object if the patient information is not input via the operation unit when the receiving unit receives the patient information.
