Intended Use

BT-220L/220C is a pocket sized ultrasonic fetal monitor that measures heart rate, which is displayed on an LCD display, and outputs fetal heart sounds through a built in speaker. The fetal heart rate is measured using Doppler ultrasound.

Device Story

Pocket-sized ultrasonic fetal monitor; measures fetal heart rate (FHR) and outputs fetal heart sounds. Operates by irradiating ultrasound waves to pregnant woman's abdomen; detects Doppler frequency signals; analyzes signals to calculate FHR. Displays FHR on LCD screen; provides audio output via built-in speaker. Used in clinical settings by healthcare providers to assess fetal well-being. Device provides real-time monitoring of fetal heart activity to assist in clinical decision-making regarding fetal health.

Clinical Evidence

No clinical data. Bench testing performed including HR accuracy measuring, acoustic output testing, and biocompatibility testing per ISO 10993.

Technological Characteristics

Pocket-sized fetal monitor; Doppler ultrasound sensing principle; continuous pulsed Doppler operating mode. Patient-contacting materials tested for biocompatibility per ISO 10993 (surface device, skin, <24 hrs). LCD display; built-in speaker.

Indications for Use

Indicated for pregnant women to monitor fetal heart rate and fetal heart sounds using Doppler ultrasound.

Regulatory Classification

Identification
