Tablet Patient Data Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices face limitations in efficiently transmitting, receiving, and displaying medical data due to constraints related to speed, performance, memory, and display size, particularly over low-speed and intermittent wireless connections, which are critical for reliable healthcare applications.
Innovation Solution
A tablet computing device is used to receive and process patient data from sensors and information systems, generating graphical representations of physiological characteristics, and displaying them on a touchscreen, with the ability to operate in a single application mode when docked, disabling non-essential functionality to ensure secure and efficient patient monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices are used to transmit and display medical data, then portability and accessibility are improved, but transmission speed and display efficiency deteriorate due to device constraints
Solution Approach 1:
The system segments data transmission by prioritizing critical patient information (alarms, vital signs) over less urgent data. The tablet device divides display content into essential monitoring data and supplementary information, allowing core medical data to be transmitted and displayed quickly even on mobile devices with limited bandwidth and screen real estate.
2Loss of information
If more patient data is displayed on mobile devices, then information completeness is improved, but memory and processing requirements increase
Solution Approach 1:
The system extracts and displays only the most critical patient monitoring data on the tablet device screen, such as real-time vital signs, alarm status, and trend indicators. Detailed historical data, full waveforms, and comprehensive patient records are stored in the docking station's database and can be accessed on demand, removing the burden of storing all information locally in the mobile device's limited memory.
3Ease of operation
If wireless connections are used for data transmission, then mobility is improved, but reliability deteriorates over low-bandwidth and intermittent connections
Solution Approach 1:
The system performs preliminary data synchronization by continuously buffering and pre-transmitting patient monitoring data to the docking station when wireless connection is available. Critical data is prioritized for transmission and stored locally in the docking station's database before needed, ensuring that when the tablet connects to the wireless network, the most important information is already available or can be quickly retrieved, maintaining reliability even with intermittent connections.
