Indications for Use
The BT-350 is a Prenatal Monitoring System for non-invasively measuring and showing graphically maternal abdominal contractions and the fetal heart rate by means of display on a non-permanent graphical display and on a strip chart recorder. This data is intended to aid in assessing the well being of the fetus during the antepatum periods(Non-Stress Test.) Therefore the Bt-350 is not used in delivery room. ,This device is for use only by trained medical personnel located in hospitals, clinics, doctor's offices and in the patient's home.
Device Story
BT-350 is a fetal monitor measuring fetal heart rate (FHR) and uterine contractions. Inputs: ultrasound waves directed at maternal abdomen; reflected Doppler frequency signals from fetal heart; pressure sensor data for uterine contractions. Device processes Doppler signals to calculate FHR; displays FHR and contraction values on LCD/LED screen; provides audible fetal heart sounds; prints data via thermal printer. Supports twin monitoring using two pulsed ultrasound transducers. Used in hospitals, clinics, doctor's offices, and patient homes by trained medical personnel. Output aids clinicians in assessing fetal well-being during antepartum periods (Non-Stress Test).
Clinical Evidence
No clinical data provided. Safety and effectiveness established via bench testing, including electrical, mechanical, and environmental safety testing per EN/IEC 60601-1 and EMC testing per EN/IEC 60601-1-2. All test results were satisfactory.
Technological Characteristics
System includes 1MHz PW Doppler fetal probe and pressure sensors. Features thermal printer, LCD/LED display, and 100-240VAC power adaptor. Supports twin monitoring. Complies with EN/IEC 60601-1 (safety) and EN/IEC 60601-1-2 (EMC).
Indications for Use
Indicated for non-invasive prenatal monitoring of fetal heart rate and maternal abdominal contractions during antepartum periods (Non-Stress Test) in pregnant women. Not for use in delivery rooms. For use by trained medical personnel in hospitals, clinics, doctor's offices, and patient homes.
Regulatory Classification
Identification
A perinatal monitoring system is a device used to show graphically the relationship between maternal labor and the fetal heart rate by means of combining and coordinating uterine contraction and fetal heart monitors with appropriate displays of the well-being of the fetus during pregnancy, labor, and delivery. This generic type of device may include any of the devices subject to §§ 884.2600, 884.2640, 884.2660, 884.2675, 884.2700, and 884.2720. This generic type of device may include the following accessories: Central monitoring system and remote repeaters, signal analysis and display equipment, patient and equipment supports, and component parts.

5. Description :
- BT-350 is the fetal monitor that measures the fetal heart rate(FHR) and uterine contraction. Using these parameters, the medical team can monitor fetal status and check uterine contraction degree. BT-350 irradiates ultrasound wave to the abdomen of a pregnant woman, and detects the Doppler frequency signal reflected from the heart of the fetus. BT-350 analyzes this signal and displays the heart rate by LCD or LED(7-

Segment). Also, BT-350 provides the sound from the heart of fetus.
BT-350 measures the uterine contraction of a pregnant woman by pressure sensors and displays the numerical values.
And BT-350 prints the heart rate of the fetus and the values of uterine contraction.
- BT-350 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-350 is capable of Twin Monitoring with two pulsed Ultrasound Transducers.
- BT-350 has a free voltage(100 240VAC input) power adaptor.
- 6. Indication for use :
- The BT-350 is a Prenatal Monitoring System for non-invasively measuring and showing graphically maternal abdominal contractions and the fetal heart rate by means of display on a non-permanent graphical display and on a strip chart recorder. This data is intended to aid in assessing the well being of the fetus during the antepatum periods(Non-Stress Test). Therefore the BT-350 is not used in delivery room. This device is for use only by trained medical personnel located in hospitals, clinics, doctor's offices and in the patient's home.
- 7. Comparison with predicate device :
Bistos Co., Ltd., believes that the BT-350 Fetal Monitor are substantially equivalent to the IFM-500 of Biosys Co., Ltd.
- 8. Safety, EMC and Performance Data :
Electrical, mechanical, environmental safety and performance testing according to standard EN/IEC 60601-1 was performed, and EMC testing was conducted in accordance with standard EN/IEC 60601-1-2(2001). All test results were satisfactory.
