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 Story

SERENO Electronic Stethoscope is a diagnostic aid for clinicians to amplify heart, lung, and body sounds. Device features a probe head, binaural pipes, and ear tips; operates via two AAA batteries. User controls include four buttons on the chest set for power, volume (12 steps), and frequency mode selection (Bell, Diaphragm, Extended). Device includes an LCD for volume, mode, and battery status. Audio output can be connected to external recording equipment or a PC via audio cable for storage/transmission; however, the device is a standalone unit with no integrated software control. Benefits include up to 20x sound amplification and selective frequency filtering to assist in patient physical assessment.

Clinical Evidence

Bench testing only. Data included electrical safety, EMC, and user testing to verify performance against predicate devices. No clinical trials were conducted.

Technological Characteristics

Electronic stethoscope; analog audio system with digital control for volume and filter mode. Frequency response: Bell (20-450Hz), Diaphragm (200-1,200Hz), Extended (20-1,500Hz). Amplification up to 20x. Power: 2x AAA 1.5V batteries. Features: LCD display, automatic power-off, 12-step volume control. Connectivity: Analog audio output jack for external recording/PC sound card input. No internal software or firmware control.

Indications for Use

Indicated for medical diagnostic purposes, specifically the amplification of heart, lung, and other body sounds for any patient undergoing a physical assessment.

Regulatory Classification

Identification

Manual stethoscope: A mechanical device used to project the sounds associated with the heart, arteries, and veins and other internal organs. Electronic stethoscope: An electrically amplified device used to project the sounds associated with the heart, arteries, and veins and other internal organs.

Special Controls

*Classification.* Class II (special controls). The device, when it is a lung sound monitor, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

- l . Identification of the Device: Proprietary-Trade Name: SERENO Electronic Stethoscope Classification Name: Electronic Stethoscope, Product code DQD Common/Usual Name: Electronic Stethoscope
- 2. Equivalent legally marketed devices 3M™ Littmann™ Electronic Stethoscope (K003723), JABES Electronic stethoscope (k031446)
- 3. Indications for Use (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.
- 4. Description of the Device: 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..
- Safety and Effectiveness, comparison to predicate device. The results of bench and user 5. testing indicates that the new device is as safe and effective as the predicate devices.
