No
The document describes basic digital signal processing for sound amplification and recording, but there is no mention of AI or ML algorithms for analysis, interpretation, or diagnosis.

No.
The device is described as being used "only for medical diagnostic purposes," indicating its role in identifying conditions rather than treating them.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "intended only for medical diagnostic purposes."

No

The device description clearly outlines physical components like a chest-piece, active speaker, passive sound tubes, OLED display, keypad, barcode reader, tube connector, and a digital signal processor. It also mentions a battery and accessories like a charger and micro SD card. These are all hardware components, indicating it is not a software-only device.

Based on the provided information, the IMEDIPLUS Electronic Stethoscope DS301 is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
  • Device Function: The IMEDIPLUS Electronic Stethoscope DS301 works by detecting, amplifying, and recording sounds directly from within the patient's body (heart, lungs, etc.). It does not analyze samples taken from the body.
  • Intended Use: The intended use clearly states it's for "detection, amplification and recording of sounds from the heart, lung... and other internal organs" and is used for "physical examination." This is a direct, non-invasive assessment of the patient's internal sounds.

Therefore, the device falls under the category of a medical device used for physical examination and diagnostic purposes in vivo (within the living body), not in vitro (in glass/outside the body).
