Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring technologies require significant equipment expenditure for continuous monitoring of cardiovascular and respiratory systems, and fail to correlate cardiac and respiration signals effectively, limiting early detection of life-threatening conditions.
Innovation Solution
A device that uses separate channels to transmit measurement data from various sensors, allowing for continuous recording and analysis of cardiac and respiratory signals over at least six hours, with the ability to identify pacemaker artifacts and detect arrhythmias, ischemias, and breathing disorders, enabling correlation of signals for early detection of vital system imbalances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If separate channels are used for transmitting measurement data from various sensors, then signal correlation capability is improved, but device complexity increases
Solution Approach 1:
The patent divides the measurement system into separate channels for different sensors (ECG, respiratory, oxygen saturation, etc.), with each channel processing and transmitting data independently. This segmentation allows simultaneous acquisition of multiple physiological parameters without signal interference, enabling comprehensive signal correlation while maintaining manageable system architecture through modular channel design.
2Reliability
If continuous recording is carried out for at least six hours, then early detection capability is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic sampling and evaluation of physiological signals at defined intervals during the continuous six-hour recording period. Instead of continuous high-power processing, the device periodically analyzes data segments, allowing early detection of cardiac and respiratory disorders while reducing overall energy consumption through intermittent rather than constant high-intensity operation.
3Measurement precision
If pacemaker artifact detection is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces a dedicated evaluation device that acts as an intermediary between the ECG sensors and the final analysis system. This intermediate component specifically processes ECG signals to detect pacemaker artifacts, isolating the complex detection algorithm from the main system architecture. This approach improves measurement precision for pacemaker artifact identification while containing device complexity within a specialized modular component.

AI summary
The arrangement has a clock system producing time signal. The control unit of the data recording arrangement records all channels of the data recording arrangement during the time signal, and assigns a time signal to each data signal. A connecting unit is implemented for optional attaching of the data recording arrangement to a personal computer or to a therapy unit. An independent claim is also included for a method for displaying and evaluation of electrocardiogram signals and breathe-dependent signals in form of a comparative representation of the different channels with one another.
