Vital Sign Data Framing for Real-Time Remote Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable monitoring devices are unable to report vital signs data in real time to a remote monitoring station, requiring the presence of a doctor or delayed tracking, which can lead to diagnostic delays.
Innovation Solution
A communication method and monitoring system that preprocesses and orders data frames with varying frequencies to efficiently transmit heart rate and respiratory rate data, allowing real-time remote monitoring with reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all sensor data is transmitted continuously at high frequency, then real-time monitoring capability is improved, but power consumption increases and device size must be larger
Solution Approach 1:
The patent implements periodic transmission of data frames at different frequencies. Critical data (heart rate, respiratory rate) are transmitted more frequently than other sensor data. The system uses periodic sampling and transmits data frames only when necessary, rather than continuous transmission, thereby reducing power consumption while maintaining real-time monitoring capability for critical parameters.
Solution Approach 2:
The patent segments sensor data into different priority levels and transmits them separately. Critical vital signs data are segmented and transmitted with higher priority and more frequent updates, while non-critical data are transmitted less frequently. This segmentation allows the system to optimize power consumption by not transmitting all data at the same high frequency.
2Productivity
If data is pre-processed and ordered in frames before transmission, then transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-processing and organizing sensor data into structured data frames before transmission. The monitoring device orders data from multiple sensors into predefined frame structures, preparing them for efficient transmission. This preliminary organization reduces the processing burden on receiving devices and improves overall transmission efficiency.
3Loss of time
If continuous real-time monitoring is implemented, then diagnostic speed is improved, but device size and power requirements increase
Solution Approach 1:
The patent applies partial action by implementing continuous monitoring only for critical vital signs parameters (heart rate, respiratory rate) while using periodic or event-triggered monitoring for other parameters. This selective monitoring approach maintains fast diagnostic capability for critical conditions while reducing the overall data processing burden and allowing for a more compact device design.

AI summary
The invention relates to a communication method for communicating monitoring data between a monitoring device (4) and processing means (6), wherein the monitoring device (4) is configured for receiving the monitoring data. The method comprises the steps of sending a byte frame to the processing means (6), storing the byte frame, ordering the byte frame by separating the frame into respiratory rate bytes, heart rate bytes and additional bytes, and repeating the previous steps with a predetermined frequency until the processing means have received a heart rate data set, a respiratory rate data set, and an additional data set. The processing means create heart rate information from the heart rate data set and create respiratory rate information from the respiratory rate data set and display them to a user.
