No
The description focuses on standard signal processing (Doppler frequency analysis) and basic data display/recording, with no mention of AI, ML, or advanced analytical techniques.
No.
The devices are designed for monitoring and recording fetal heart rate and maternal contractions, which is a diagnostic function rather than a therapeutic one. They do not treat or alleviate a medical condition.
Yes
The device measures and records maternal contraction and fetal heart rate, which are used to "predict fetal status" and "predict fetal well-being." This involves the assessment of a biological state to determine the presence or absence of a medical condition or risk, fitting the definition of a diagnostic device.
No
The device description explicitly mentions hardware components such as Doppler Ultrasound transducers, pressure sensors, LED/LCD displays, a strip chart recorder, a thermal printer, and a power adaptor. It is a physical device that utilizes software for data processing and display, but it is not solely software.
Based on the provided information, the BT-300 and BT-200 devices are not In Vitro Diagnostic (IVD) devices.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information about a person's health. This testing is performed outside of the body (in vitro).
- Device Function: The BT-300 and BT-200 devices use Doppler Ultrasound to measure fetal heart rate and uterine contractions directly on the pregnant woman's abdomen. This is an in vivo measurement, not an in vitro test of a specimen.
- Intended Use: The intended use is to monitor fetal heart rate and maternal contractions, which are physiological measurements taken from the living body.
Therefore, these devices fall under the category of medical devices used for monitoring physiological parameters, not IVD devices.

Device Description
BT-300 is the fetal monitor that measures the fetal heart rate(FHR) which may be evaluated to predict fetal status and uterine contraction. BT-300 irradiates ultrasound wave to the abdomen of a pregnant woman, and detects the Doppler frequency signal reflected from the heart of the fetus. BT-300 analyzes this signal and displays the heart rate by LED. Also, BT-300 provides the sound from the heart of fetus.
BT-300 measures the uterine contraction of a pregnant woman by pressure sensors and displays the numerical values.
And BT-300 prints the heart rate of the fetus and the values of uterine contraction.
BT-300 records the heart rate of the fetus, the uterine contraction of a pregnant woman, and basic information of the equipment with a provided thermal printer.
BT-300 is capable of Twin Monitoring with two pulsed Ultrasound Transducers.
BT-300 has a free voltage(100 240VAC input) power adaptor.
BT-200 is a pocket-size fetal Monitor that measures the fetal heat rate and outputs the fetal heart sound through built-in speaker. By measuring fetal heart rate(FHR), you are able to predict fetal well-being. BT-200 irradiates fetal wave to the abdomen of a pregnant woman to detect the Doppler frequency signal and analyze, and displays the heart rate on LCD screen. The device also provides the heart sound from the heart of fetus.

Dear Mr. Mouser:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
This determination of substantial equivalence applies to the following transducers intended for use with the BT-300, BT-200 Fetal Monitor, as described in your premarket notification:
Transducer Model Number

it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus permits your device to proceed to market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120.
