Stethoscope TRIZ Cases
- Vascular Sound Detection for Continuous Cardiovascular Monitoring
Acoustic sensors isolate 100-300 Hz frequencies to identify dicrotic notches, replacing complex ultrasound equipment with simple signal processing.
- Inspection Device Integrating ECG and Temperature Sensors
An inspection device merges electrocardiogram sensing with acoustic detection in a single unit.
- Automated Lung Sound Classification Without Flowmeter Reference
Processor-based system extracts spectral and wavelet features from auscultation signals to classify healthy versus abnormal lung sounds.
- Auscultation Noise Reduction Assembly with Dampening Layers
Multi-chamber auscultation device captures high-frequency acoustic signals via transducers while dampening layers reduce ambient noise interference.
- Chest-Worn Patch Sensor for Continuous Vital Sign Monitoring
A chest-worn patch sensor integrates ECG, PPG, and impedance electrodes to measure vital signs wirelessly.
- Non-invasive Cardiac Monitoring via Lightning-Thunder Interval
Smartphone platform processes electrocardiographic and seismocardiographic signals to measure the Lightning-Thunder interval for beat-by-beat cardiac assessment.
- Respiratory Sound Sensor Circuit for Ambulatory Disease Detection
Sensor circuit captures respiratory sounds and spectral analyzer generates frequency band data to identify anomalies.
- Antimicrobial Copper Stethoscope Diaphragm with Axial Compliance
A copper stethoscope diaphragm employs an annular axially compliant suspension to resolve contamination risks while preserving acoustic-transduction properties.
- Integrated Patient Parameter Sensor for Simultaneous Diagnosis
A multi-sensor device measures temperature, body sounds, and oxygen levels simultaneously.
