01. Product and Features
This product is 『Medical device』 which is registered KFDA (No. 11-716).
Our Wireless Digital Stethoscope makes it possible to analyze heart, lungs or intestines sounds
from a body and make a diagnosis through these data.
This stethoscope makes it possible to select 3 sound measurement modes (Bell, Diaphragm,
Wide) depending on the bandwidth.
This stethoscope is easy to use while making measurements on the body. Also, while this
stethoscope is connected USB dongle, you can easily monitor the progress by wireless connection.
This connection is effective at a five-meter distance, and because of its micro processor and filter,
the signal strength and reliability of the wireless connection is enhanced.
This stethoscope removes the inconvenience of battery replacement by equipping a built-in large
capacity secondary battery.
This stethoscope can be used for a long time(approximately 54 hours in continuous use) with a
single charge due to the low voltage and low power circuit design.
This stethoscope makes it possible to monitor and save stethoscope sounds through the
“VPM3000W” software. This software also makes it possible to analyze, replay and edit
stethoscope sounds by spectrogram, detect and display inaccurate data using LCR algorithm, and
input basic information for medical diagnostics (body temperature, blood pressure, pulse and
oxygen saturation level) conveniently.
This stethoscope is very good for usability and portability as it is designed for ergonomics.
