More Information

No
The summary describes a standard electronic stethoscope with Bluetooth transmission and sound amplification. There is no mention of AI, ML, or any form of automated analysis or interpretation of the sounds. The performance studies focus on basic device functionality, safety, and usability, not algorithmic performance.

No

Explanation: The device is used for detection of sounds for diagnosis, not for treating any condition.

Yes
The "Intended Use / Indications for Use" section explicitly states that the device "can only be used for the purpose of medical diagnosis in clinics or hospitals."

No

The device description clearly outlines hardware components such as a chest piece, power button, indicators, battery power, and accessories like earphones and audio lines, indicating it is a physical device with integrated software, not a software-only device.

Based on the provided information, the ibiomedi Electronic Stethoscope ES-2020 is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • IVD devices are used to examine specimens derived from the human body. The description of the ibiomedi Electronic Stethoscope ES-2020 clearly states it is used to detect sounds from the body (heart, arteries, veins, breathing sounds, throat sounds). It does not involve the analysis of blood, urine, tissue, or other bodily fluids or substances.
  • The intended use and device description focus on the physical detection and transmission of sounds. This is a diagnostic tool that works by listening to internal body sounds, not by analyzing biological samples.

Therefore, the ibiomedi Electronic Stethoscope ES-2020 falls under the category of a medical device used for physical examination, not an in vitro diagnostic device.

11. Indications for Use:

The ibiomedi Electronic Stethoscope ES-2020 is used to detect sound from the heart, arteries, veins, breathing sounds from the anterior/lateral chest and throat sounds in the neck. The chest piece is designed for children who are over two years old, teenagers and adults. It can be applied to any body type and can only be used for the purpose of medical diagnosis in clinics or hospitals.

12. Comparison of Technological Characteristics with The Predicate Device:

The ibiomedi Electronic Stethoscope ES-2020 uses a miniature microphone to pick up sound through the chest piece and uses noise-cancelling technology to filter murmurs to distinguish heart sounds with a frequency of 20200Hz, lung sounds with a frequency of 1001000Hz, and all sounds within 1200Hz. And it can amplify the sound up to 50X, which is helpful for medical personnel to make judgments.

At a high level, the subject and predicate devices are based on the following same technological elements:

  • . Chest piece & miniature microphone: To use a miniature microphone to pick up sound through the chest piece.
  • Noise-cancelling technology: To filter murmurs and distinguish the frequency.
  • . Sound amplification: To amplify sound of specific frequency.

The following technological differences exist between the subject and predicate devices:

  • Use earphones instead of ear tubes.
  • . Replaceable chest piece.
  • Use only AAA alkaline batteries.
