Indications for Use

The Bidop 7 is intended for the detection of arterial and venous blood flow in the extremities as well as fetal heart sounds. The Bidop 7 displays bi-directional velocity waverical data and fetal heart rate with heartbeat indicator. The Bidop 7 probe selection is 2, 5, 8, and 10 MHz.

Device Story

Bidop 7 is a non-invasive diagnostic system for peripheral vascular evaluation and fetal heart monitoring. It utilizes ultrasonic Doppler probes (2, 5, 8, 10 MHz) to detect blood flow velocity and fetal heart sounds, and an infrared PPG probe for surface vessel hemoglobin reflection. The device amplifies high-frequency oscillations, converts them to ultrasound, receives reflected signals, filters noise, and processes Doppler shifts. Outputs include audible sounds via speaker, bi-directional velocity waveforms, and numerical data (systolic segmental pressures, ABI, TBI, fetal heart rate). Used in clinical settings by healthcare providers to assess vascular pathology and fetal status. The device aids clinical decision-making by providing quantitative and qualitative hemodynamic data, potentially benefiting patients through early detection of peripheral vascular disease or monitoring of fetal well-being.

## Device description:

The Bidop 7 is designed to provide both qualitative and quantitative information. The qualitative information mainly includes color visual display of waveform's shapes, including qualitative analysis of Photoplethysmography (PPG) and Doppler waveforms. The quantitative information is focused primarily on aiding the examiners in obtaining systolic segmental blood pressures, including the ABI (ankle-brachial index) and TBI (toe-brachial index). Additional quantitative measurements relate to the Doppler blood flow velocity waveforms.

## Clinical Applications:

The Bidop 7 clinical applications are:

| ABI and TBI studies | Bi-directional Doppler extremity studies |
|----------------------------------|------------------------------------------|
| Blood pressure segmental studies | PPG toe pressure & venous reflux studies |

# Principles:

Doppler blood velocity measurement and sounds for systolic pressures:

While obtaining Doppler arterial waveforms, blood flow velocity is detected through the ultrasound which is transmitted from probe to patient body and is reflected by the blood (hemolytic, etc.).

The unit amplifies the high frequency oscillation output and then supplies it to the transmitter transducer. It is converted to ultrasound by the transducer and the ultrasound is transmitted to external objects. The ultrasound moves straight through biophysical object and is reflected by the moving object (blood flow, fetal heartbeat etc.).

The reflected ultrasound is received by the receiving transducer and is converted into electric signals again.

The converted signals are amplified and then detected. After removing unnecessary noise from the signals and improving S/N ratio at the filter circuit, the Doppler shift signals are amplified and are converted to audible sounds through a speaker.

Simultaneously, the Doppler shift signals are applied to the CPU and converted to blood flow velocity waveform signals which can be displayed.

# Photoplethysmography:

While taking toe pressures and/or waveforms with PPG probe as well as performing PPG venous reflex study, the unit senses the reflection of light from the hemoglobin of the red blood cells in surface vessels by utilizing infrared light with the probe.

# Probes:

| Model name | | Freq. | Probe power (In situ) |
|----------------|-----------|-------|-----------------------|
| Doppler probe: | ST8M05S8C | 8MHz | 720 mW/cm² or less |
| Doppler probe | ST5M05S8C | 5MHz | 720 mW/cm² or less |
| Doppler probe | ST10M5S8C | 10MHz | 720 mW/cm² or less |
| Doppler probe | ST2M05S8C | 2MHz | 94 mW/cm² or less |
| PPG probe: | PG-30 | | |

# Indication for Use Statement:

# Literature Review:

A review of the literature pertaining to the safety of the Bidop 7 range of non-invasive peripheral vascular diagnostic systems has been conducted and appropriate safeguards have been incorporated in the of the Bidop 7 of non invasive peripheral vascular diagnostic devices.

## Conclusions:

The conclusion drawn from these tests is that the Bidop 7 non-invasive peripheral vascular diagnostic system is equivalent in safety and efficacy to the predicate device. Therefore, the Bidop 7 is substantially equivalent to the predicate.
