Fetal Doppler
Additional Description
Detect the blood stream status of arterial/venous by 8.0 MHz, detect the blood flow average velocity, and detect the result of finger/toes and part of body’s vein anatomies operation; Ultrasonic frequency: 8.0MHz±10% (5.0MHz for option) Speed measuring range: 0--100cm/s Graphic display range:0--60cm/s Speed measuring error: < 20%(comparative error) The bloodstream average is obtained according to upper graphics of the three former pulse beating. Gain:> 100dB Equivalent noise:<200NV(input port) Battery: 14.4V/1600mAhNi-MH rechargeable batteries Power: 24V/1.5A Frequency band: Main unit: 200±80-5000±1000Hz Probe: 350±80-2500±500Hz Audio band width: 200Hz-7000Hz Transmit graphics: sine wave Output: loudspeaker single track earphone jack Indication way: Display the waveform and the detecting result of the blood stream average velocity and the spectrum line, spectrum line and waveform indicate the direction and contrast direction of the blood stream speed, probes detect the optimal position Power indicator: LBD(blue) Green for working and orange for lack of paper. Audio frequency output: Vascular Doppler Sound No distorted power:> 10mW Output signal: bloodstream speed, bloodstream intensity, blood stream sound Output impedance: Blood stream speed 5KΩ, acceleration 5KΩ, audio Doppler blood stream1KΩ Charging indication: yellow for charging, green for full-charge
