Intended Use
The SERENO Electronic Stethoscope is intended for medical diagnostic purposes only. It can be used for the amplification of heart, lung and other body sounds with the use of selective frequency and can be used on any patient undergoing a physical assessment.
Device Description
The SERENO electronic stethoscope is intended for use as a diagnostic aid in patient diagnosis and monitoring. The SERENO electronic stethoscope amplifies sounds up to 20 times bigger than ordinary acoustic stethoscope in a broad frequency range including a range higher than the traditional diaphragm mode. It looks similar to the traditional stethoscope including parts like a probe head, binaural pipes and ear tips. It has four (4) buttons on the top of the chest set (opposite to the probe). Each of the buttons has a function of controlling the modes, volume up/down and power on/off. As an electronic stethoscope, it needs two (2) batteries (AAA type, 1.5V) to operate. The stethoscope has automatic power off function for longer battery life and has a LCD display to show volume level, frequency mode and low battery indicator. With the enclosed audio cable. utilizing a personal computer, the user can store sound signals in the PC and transmit diagnosis data via e-mail. This stethoscope is a stand-alone unit, has no software and operates using an analog audio system with a digital timer for power saving and a digital control for the volume and the filter mode selection. It can be connected to audio input of a sound card in a computer to use the PC software functions. However, the software does not operate nor control the stethoscope in any manner. In fact, the stethoscope's audio output can be connected to any ordinary audio equipment such as a cassette recorder, a hi-fi audio component and portable audio.
More Information

No
The device description explicitly states that it is a stand-alone unit, has no software, and operates using an analog audio system with digital controls for volume and filter mode selection. It also clarifies that while it can connect to a PC for sound storage, the PC software does not operate or control the stethoscope. There is no mention of AI, ML, or related concepts.

No
The device is described as being for "medical diagnostic purposes only" and as a "diagnostic aid," not for treatment.

Yes

The product's "Intended Use / Indications for Use" states that it "is intended for medical diagnostic purposes only." Additionally, the "Device Description" states it "is intended for use as a diagnostic aid in patient diagnosis and monitoring."

No

The device description explicitly states, "This stethoscope is a stand-alone unit, has no software and operates using an analog audio system with a digital timer for power saving and a digital control for the volume and the filter mode selection." It also describes physical components like a probe head, binaural pipes, ear tips, and buttons, and requires batteries to operate. While it can connect to a PC for data storage, the stethoscope itself is described as hardware-based with no controlling software.

Based on the provided information, the SERENO Electronic Stethoscope is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens taken from the human body. The intended use and device description clearly state that the SERENO Electronic Stethoscope is used for the amplification of body sounds (heart, lung, etc.) directly from the patient during a physical assessment. It does not involve the analysis of biological samples.
  • The device operates using an analog audio system. While it can be connected to a computer for recording, the core function is the amplification and filtering of sounds, not the analysis of in vitro samples.

The description aligns with a medical device used for physical examination and diagnosis based on auscultation, which is a different category than IVD.
