No
The device description relies on traditional Doppler ultrasound principles and signal processing, with no mention of AI or ML techniques. The performance studies focus on equivalence to predicate devices using standard testing, not AI/ML specific validation.
Yes
The device is intended for detection of fetal heart rate and monitoring during labor, which are medical purposes related to patient health and management.
Yes
The device is intended for "Detection of fetal heart rate, detection of multiple pregnancies. Verify fetal heart viability following patient trauma. Display of fetal heart rate, monitor fetal heart rate during labor." These uses involve identifying a condition or monitoring a physiological state, which falls under the definition of a diagnostic device.
No
The device description explicitly details hardware components like transducers, amplifiers, filters, speakers, and an LCD display, indicating it is a physical 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 Echo Sounder ES-102EX Fetal Doppler system uses ultrasound to detect and monitor the fetal heart rate externally on the patient's body. It does not analyze samples taken from the body.
- Intended Use: The intended uses listed (detection of fetal heart rate, multiple pregnancies, verifying fetal heart viability, displaying and monitoring fetal heart rate) are all performed non-invasively on the patient.
Therefore, this device falls under the category of a medical device used for monitoring and diagnosis in vivo (within the living body), not in vitro.

Intended Use / Indications for Use
Detection of fetal life, detection of multiple pregnancies, fetal screens from early gestation through delivery and general indication of fetal well being. Verify fetal heart viability following patient trauma.
Detection of fetal heart rate, detection of multiple pregnancies. Verify fetal heart viability following patient trauma. Display of fetal heart rate, monitor fetal heart rate during labor.

Device Description
The Echo Sounder ES-102EX Fetal Doppler system utilizes the well understood principle of Doppler shift of an ultrasound signal to detect the flow of blood within the fetal heart wall motion and arteries.
The unit amplifies the high frequency oscillation output and then supplies this to the transmitter transducer. The high frequency voltage is converted to ultrasound by the transducer and is transmitted to external objects. The ultrasound transmitted by the transducer movers straight through biophysical object(s), and is reflected by the moving object (fetal heartbeat etc.). The reflected ultrasound is received by the receiving transducer and is converted into electronic signals again.
The converted electronic signals are amplified and then are detected. After removing unnecessary noise signals and improving S/N ratio at the filter circuit, the Doppler shift signals are amplified and are converted to audible sound pressure through a speaker or a headset. Simultaneously the signals are applied to the heart rate LCD display.

§ 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).

Trade Name: Echo Sounder, Model ES-102EX Fetal Doppler Regulation Number: 21 CFR 884.2660 Regulation Name: Fetal ultrasonic monitor and accessories Regulatory Class: II Product Code: 85 KNG Dated: September 19, 2002 Received: September 20, 2002
Dear Mr. Knauss:
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 Echo Sounder, Model ES-102EX, as described in your premarket notification:
Transducer Model Number
2 MHz CW Doppler Transducer, Model T2M20N8A
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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 (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Page 2 - Mr. Knauss
This determination of substantial equivalence is granted on the condition that prior to shipping the first . device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.
The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:
Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850
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 (301) 594-4591. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled. "Misbranding by reference to premarket notification" (21 CFR Part 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-041 or at (301) 443-6597 or at its Internet address "http://www.fda.gov/cdrh/dsmamain.html".
