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 low-bandwidth wireless connections, which are critical for reliable medical data communication.
Innovation Solution
The implementation provides methods for receiving and processing patient data to generate graphical representations, including waveforms, and displaying calipers associated with waveform segments, allowing for user input to update measurement values and scroll through different time periods, utilizing a computing device with processors and a computer-readable medium to execute instructions for secure and efficient data delivery across healthcare continua.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If patient data is transmitted over mobile devices with limited bandwidth and speed, then data transmission reliability is maintained, but data transmission speed and efficiency deteriorate
Solution Approach 1:
The patent segments patient data into different categories (critical real-time data vs. historical data) and transmits them using different methods. Critical data is transmitted continuously over wireless connections, while historical data is cached locally. This segmentation allows the system to maintain reliability for critical data while accepting slower transmission speeds for non-critical data, resolving the contradiction between reliability and speed.
Solution Approach 2:
The system performs preliminary actions by pre-loading and caching patient data locally before it is needed. Historical waveform data and patient information are stored in local memory, allowing the system to function independently of continuous network connectivity. This preliminary action ensures reliability during transmission interruptions while reducing the need for frequent slow transmissions.
2Loss of information
If detailed waveform data is displayed on mobile devices with limited display size, then data completeness is maintained, but display clarity and usability deteriorate
Solution Approach 1:
The patent segments the waveform display into multiple time periods, with each period representing a specific duration (e.g., 1 minute, 5 minutes). Users can select which time period to display, allowing detailed waveform data to be presented clearly on small screens without overwhelming the limited display area. This segmentation maintains data completeness while adapting to the constraints of mobile device displays.
Solution Approach 2:
The system dynamically adjusts the displayed waveform time period based on user interaction and clinical needs. Users can scroll through different time periods, and the system can automatically adjust the display based on detected events or user preferences. This dynamic adaptation allows detailed data to be displayed clearly on limited screens by focusing on relevant portions rather than attempting to show everything simultaneously.
3Loss of information
If multiple data layers are displayed simultaneously on mobile devices, then information comprehensiveness is improved, but system complexity and processing requirements increase
Solution Approach 1:
The patent segments patient data into distinct layers: critical real-time physiological data, historical waveform data, and patient demographic information. Each layer is processed and displayed separately, with the system managing complexity by handling one layer at a time. This segmentation maintains information comprehensiveness while reducing the processing burden on mobile devices with limited computational resources.
Solution Approach 2:
The system performs preliminary processing by pre-filtering and organizing data into layers before display. Historical data is pre-processed and cached, while critical data is continuously monitored. This preliminary organization reduces the complexity of displaying multiple data types simultaneously, as the system already knows which data needs immediate attention and which can be displayed in the background.
