Stethee Pro 1, Stethee Pro Software System

The Stethee Pro 1 System is an advanced electronic stethoscope designed for comprehensive auscultation, utilizing digital signal processing and Bluetooth connectivity for sound capture and transmission. Its accompanying software system leverages cloud-based architecture and machine learning algorithms to provide enhanced diagnostic capabilities, including sound visualization, heart rate and respiration rate analysis, and collaborative data management for healthcare professionals.

The Stethee Pro 1 System is an electronic auscultation device intended for medical screening and diagnostic applications. It functions by capturing internal body sounds, such as those from the heart, lungs, and vasculature, using a microphone sensor and offers amplification with selectable frequency filters. The device employs digital signal processing for sound refinement and features user interface elements like volume control, haptic feedback, and an LED display. Audio output is available in real-time through either Bluetooth-connected headphones or newly added wired headphones via a USB port adapter. The Stethee Pro 1 hardware itself does not retain patient data but wirelessly streams an audio buffer to an associated smart device for further processing. The core analytical and data management capabilities are provided by the Stethee Pro Software System (SPS), encompassing mobile and web-based applications supported by M3DICINE Cloud Services. The SPS facilitates the recording, playback, and advanced visualization of captured sounds as phonocardiograms and, newly, spectrograms. It incorporates machine learning algorithms to analyze these sounds for determining heart rate (within a 30-200 BPM range), new features like heart cycle (systole/diastole) duration, and respiration rate (clinically validated for 6-50 breaths/min). Additional functionalities introduced include geolocation tagging of samples, comparative analysis of patient data over time, secure data sharing capabilities among authorized healthcare professionals, and automated report generation. The system's performance, particularly the accuracy of its analytical algorithms, was substantiated through bench testing, comprehensive software validation, and clinical validation studies against established medical reference devices.
