1Reliability

If breathing prompts are issued based on therapist intuition and emotional states, then the subject may experience positive emotional effects, but the method becomes unpredictable and difficult to reproduce

Engineering Contradiction:

Improvepredictability and reproducibility of heart rate variability influenceVSAvoiddependence on therapist skills and subject-therapist relationship

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses automatic detection and analysis of the subject's physiological signals (ECG, respiration) to generate breathing prompts without requiring a therapist's continuous intervention. The processor autonomously identifies R-waves, determines electrical diastole timing, and issues prompts based on objective measurements rather than subjective therapist judgment, making the system self-sufficient and reproducible

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical/subjective system of therapist intuition and emotional assessment with an automated electronic system that objectively measures physiological parameters. The processor uses algorithmic analysis of ECG waveforms and respiration signals to determine optimal prompt timing, substituting human judgment with measurable physical phenomena

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If breathing prompts are issued at turning points of heart rate variability, then heart rate variability coherence is improved, but the timing must be precisely synchronized with physiological cycles

Engineering Contradiction:

Solution Approach 1:

The system continuously monitors the subject's ECG and respiration signals in real-time, using the detected physiological state to dynamically adjust prompt timing. The processor provides feedback control by comparing actual heart rate variability patterns against target patterns and adjusting the timing of breathing prompts to maintain optimal synchronization with the subject's physiological cycles

Inventive Principle:

Solution Approach 1:

The system uses a single processor to perform multiple functions: detecting R-waves in the ECG signal, calculating heart rate variability, determining electrical diastole timing, analyzing respiration patterns, and generating breathing prompts. This multi-functional approach achieves precise stimulus timing without requiring separate dedicated devices for each measurement and control function

AI summary

The invention relates to the creation and output of a stimulus and/or an instruction to breathe for a human and/or an animal, wherein a heartbeat signal of the human or animal is recorded and transmitted to an evaluation unit (2), wherein a predeterminable stimulation time range between two heartbeats is determined within the heartbeat signal by the evaluation unit (2). According to the invention, a first stimulus and/or a first instruction to breathe is generated by the evaluation unit (2) at a first time (4) within the stimulation time range of a predeterminable starting heartbeat and is transmitted to a signal unit (5), and the signal unit (5) outputs the first stimulus and/or the first instruction to breathe in the form of a signal.
