No
The description details standard Doppler ultrasound technology and signal processing, with no mention of AI, ML, or related concepts.

No
The device is used for detection and display of fetal heart rate, which is a diagnostic function, not a therapeutic one.

No

The device is used to detect and display fetal heart rate, which is a measurement, not a diagnosis.

No

The device description explicitly states it is a "hand-held FHR detection device" with "two hand-held components, a main unit and a probe," and contains hardware components like an "ultrasonic signal transmitter and receiver." This indicates it is a physical hardware device, not software-only.

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

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Pocket Fetal Doppler uses Doppler ultrasound to detect the fetal heart rate externally on the pregnant person's abdomen. It does not analyze samples taken from the body.
  • Intended Use: The intended use is to detect fetal heart rate, which is a physiological measurement, not a diagnostic test performed on a biological sample.

Therefore, the device falls under the category of a medical device used for monitoring, not an in vitro diagnostic device.

§ 884.2660 Fetal ultrasonic monitor and accessories.

(a)
Identification. A fetal ultrasonic monitor is a device designed to transmit and receive ultrasonic energy into and from the pregnant woman, usually by means of continuous wave (doppler) echoscopy. The device is used to represent some physiological condition or characteristic in a measured value over a period of time (e.g., perinatal monitoring during labor) or in an immediately perceptible form (e.g., use of the ultrasonic stethoscope). This generic type of device may include the following accessories: signal analysis and display equipment, electronic interfaces for other equipment, patient and equipment supports, and component parts. This generic type of device does not include devices used to image some relatively unchanging physiological structure or interpret a physiological condition, but does include devices which may be set to alarm automatically at a predetermined threshold value.(b)
Classification. Class II (performance standards).
