Remote Control Device Warning Notification in Medical Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical systems where a medical device communicates with a remote control device, communication delays or failures can lead to unreliable notification of critical warnings, potentially causing unexpected troubles during medical treatments.
Innovation Solution
The medical system includes a medical device and a remote control device with distinct notification modes, where the medical device provides warnings through visual, auditory, and tactile notifications, while the remote control device may only display warnings visually or not at all, ensuring more reliable notification to the user even in cases of poor communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote control device performs mirroring control with the same display contents as the medical device, then the user interface consistency is improved, but the reliability of warning notification deteriorates when communication fails
Solution Approach 1:
The patent applies local quality by differentiating the notification behavior between the medical device and remote control device. The medical device displays warnings with full notification (visual, auditory, tactile), while the remote control device displays warnings without active notification. This localized differentiation in notification intensity resolves the contradiction by maintaining UI consistency for normal operations while ensuring reliability for critical warnings through the primary medical device.
Solution Approach 2:
The patent introduces the communication unit as an intermediary that mediates warning notification between the medical device and remote control device. The communication unit transmits warning information from the medical device to the remote control device, but the remote control device acts as a passive display only, not generating independent notifications. This intermediary role ensures that the remote control device maintains UI consistency while relying on the medical device for reliable warning notification.
2Reliability
If the remote control device independently notifies warnings, then the notification coverage is improved, but the system complexity increases
Solution Approach 1:
The patent extracts the warning notification function from the remote control device, leaving only the display function. The remote control device receives warning information through communication but does not independently generate or notify warnings. This extraction simplifies the remote control device while maintaining notification coverage through the medical device's independent notification capabilities.
3Reliability
If the medical device provides multiple notification modes (visual, auditory, tactile), then the warning effectiveness is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple notification modes (visual display, auditory output, tactile feedback) into the medical device's integrated control system. The control unit coordinates these different notification modes to provide comprehensive warning effectiveness. This merging approach improves warning effectiveness while managing complexity through unified control rather than separate independent systems.
Data Source
AI summary
In a medical system, a medical device includes a first display that displays a figure or a character corresponding to data relevant to medical treatment performed in the medical device, and a first controller that causes the first display to display the figure or the character corresponding to the data and that, when the data satisfies conditions for notification of a warning, causes the medical device to emit a first warning. A remote control device includes a second display that displays the figure or the character corresponding to the data, and a second controller that causes the second display to display the figure or the character corresponding to the data and that, when the data satisfies the conditions for notification of the warning, causes the remote control device to emit a second warning that is different than the first warning.
