No
The summary describes a simple, disposable esophageal stethoscope for monitoring basic physiological sounds and temperature. There is no mention of AI, ML, image processing, or any data analysis that would suggest the use of such technologies.

No

The device is described as a stethoscope for monitoring heart and breath sounds and core temperature, which are diagnostic/monitoring functions, not therapeutic.

No
The device is used for monitoring heart, breath sounds, and core temperature, which falls under general patient monitoring rather than diagnosing a specific disease or condition.

No

The device description explicitly states "Disposable Esophageal Stethoscope," indicating a physical hardware component.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Function: The description clearly states the device is an "Esophageal Stethoscope" used for "Monitoring heart and breath sounds, and core temperature." This involves directly monitoring physiological signals within the body, not analyzing specimens taken from the body.

Therefore, this device falls under the category of a medical device but not specifically an In Vitro Diagnostic.
