Indications for Use
The SD5 Ultrasonic TableTop Doppler (hereinafter called "SD5") and SD6 Ultrasonic TableTop Doppler (hereinafter called "SD6") are intended to be used by health care professionals including registered nurses, practical nurses, midwives, ultrasound technicians, and physician assistants, by prescription from licensed physicians in hospitals, clinics and private offices. The 2 MHz and/or 3 MHz obstetrical probes are indicated for the detection of fetal heart rate from early gestation thru delivery and as a general indication of fetal well being. They can also be used to verify fetal heart viability.
Device Story
Hand-held tabletop Doppler device for non-invasive fetal heart rate (FHR) monitoring. Uses 2 MHz or 3 MHz ultrasound probes to transmit acoustic energy to maternal abdomen; reflected ultrasound from fetal heart and blood flow is received by probe and converted to electrical signals. Main unit performs digital processing of waveform data for display on LED screen; audio signals routed to speaker. SD5 uses wired connection; SD6 uses Bluetooth for signal transfer. Powered by AC mains or internal Ni-MH battery; probes powered by internal Lithium battery. Used in hospitals, clinics, and private offices by clinicians to assess fetal well-being and viability. Output provides real-time FHR data to assist clinical decision-making during pregnancy and labor.
Clinical Evidence
No clinical data provided. Substantial equivalence supported by bench testing, biocompatibility evaluation (ISO 10993-1), electrical safety, EMC, and software verification/validation.
Technological Characteristics
Tabletop Doppler system. Materials: shell of probe and wire jacket identical to K150901. Sensing: Doppler shift of ultrasound (2 MHz/3 MHz). Power: AC (100-240V) or Ni-MH battery (main unit); Lithium battery (probes). Connectivity: Wired (SD5), Bluetooth (SD6). Safety: Class I, Type BF applied parts. Standards: IEC 60601-1, IEC 60601-2-37, IEC 60601-1-2, ISO 10993-1, IEC 62304.
Indications for Use
Indicated for detection of fetal heart rate from early gestation through delivery, general indication of fetal well-being, and verification of fetal heart viability in pregnant patients. Used by healthcare professionals (nurses, midwives, ultrasound technicians, physician assistants) via prescription.
Regulatory Classification
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.

| 5. Device<br>Description: | The SD5&SD6 Ultrasonic Tabletop Doppler is a hand-held device for non-invasive measurement and display of fetal heart rate utilizing the principle of Doppler shift of an ultrasound. The ultrasound is transmitted from the probe to patient body (maternal abdominal wall), and moves through biophysical objects. The acoustic ultrasound is reflected by blood and moving objects such as the fetal heart. The reflected ultrasound is received by the probe and is converted into electric signals. The waveform data are applied to the CPU for all the digital processing on LED Display, operation keys. The audio signal is taken off for the routing to the speaker to generate the analogue signals before digital processing. The system is compatible with 2 MHz or 3 MHz for fetal heart rate. The signal acquired can be transferred to SD5 by wired method, and by Bluetooth to SD6.<br>The main unit can be powered by main supply (100 V-240 V~) or Ni-MH Battery (7.2 V/2000 mAh). And transducers are powered by 3.7 V/800 mAh Lithium Battery only. |
