Intended Use
The Pocket Fetal Doppler (Models CONTEC 10D, CONTEC 10E and CONTEC10F) is used to detect the fetal heart rate. The device should be used by health care professionals including nurses, midwives, and specialized technicians in the hospital, clinic, community and home. The device is intended for use at or after 12 weeks gestation.
Device Description
The Pocket Fetal Doppler is a hand-held fetal Doppler used for non-invasive measurement and numerical display of the fetal heart rate (FHR) utilizing pulsed-wave Doppler ultrasound. The Pocket Fetal Doppler includes three models: CONTEC10E and CONTEC10E and CONTEC10F. All models have four components: upper shell, display and probe. The material for probe cap and shell is ABS. The device contains an ultrasonic signal transmitter and receiver, analog signals processing unit, FHR calculating unit, and LCD display control unit. The device is used to detect the fetal heart rate. The device should be used by health care professionals including nurses, midwives, and specialized technicians in hospital, clinic, community and home. This device can detect a fetal heart rate value at or after twelve weeks gestation. The CONTEC10D is powered by a 3.7V lithium battery, the ultrasonic signal is continuously transmitted at a frequency of 2.5MHz. The CONTEC10E and CONTEC10F is powered by two 1.5V batteries (AA LR6), the ultrasonic signal is continuously transmitted at a frequency of 2.5MHz.

No
The device description details standard signal processing and calculation units, and there is no mention of AI, ML, or related concepts in the document.

No.
The device is used to detect and display fetal heart rate, which is a diagnostic function, not a therapeutic one.

Yes

This device is used to detect and display the fetal heart rate, which is a measurement used for diagnostic purposes (monitoring fetal well-being). The "Intended Use" explicitly states it's for detecting fetal heart rate, and the "Device Description" details its function for "non-invasive measurement and numerical display." Furthermore, the performance testing section references "Medical electrical equipment - Part 2-37: Particular requirements for the basic safety and essential performance of ultrasonic medical diagnostic and monitoring equipment," directly linking it to diagnostic use.

No

The device description explicitly states it includes hardware components such as an upper shell, display, probe, ultrasonic signal transmitter and receiver, analog signals processing unit, FHR calculating unit, and LCD display control unit. It also mentions being powered by batteries. While software verification and validation are mentioned, the device is clearly a physical device with integrated software, not a software-only device.

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

Here's why:

  • IVDs analyze samples taken from the human body. The description clearly states the Pocket Fetal Doppler uses non-invasive measurement utilizing pulsed-wave Doppler ultrasound to detect the fetal heart rate. It does not involve collecting or analyzing biological samples like blood, urine, or tissue.
  • The intended use is direct measurement of a physiological parameter. The device directly measures the fetal heart rate in vivo (within the body) using ultrasound technology. This is characteristic of a diagnostic device, but not an in vitro diagnostic device.

Therefore, while it is a medical device used for diagnostic purposes (detecting fetal heart rate), it does not fit the definition of an In Vitro Diagnostic.

§ 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).
