	dedicated wide range diagnosis of the neck, extra-cranial, upper and lower extremities vessels enables easy and reliable diagnosis of blood flow in peripheral arteries dedicated many applications quick assessment of blood flow by vascular surgeon prophylactic in diabetics extra-cranial circulation in neurology penile flow in urology vascular disease screening in family medicine used with sphygmomanometer allows evaluation of ABI - ankle/brachial systolic pressure index simple, pocket size device with high sensitivity and good sound quality built-in loudspeaker and possibility to listen signal only by doctor (through the headphones) powered by rechargeable battery, offered with battery charger, headphones, ultrasound gel, in comfortable carrying case The pocket size Doppler blood flow detector is a simple device enabling a wide range diagnosis of the neck, extra-cranial, upper and lower extremities vessels. Very small dimensions of device, built-in loudspeaker and power supply with rechargeable battery, it all makes the device useful both at the surgery, hospital and at patient home. MD4 may be used directly at the patients bad, when the quick clinical assessment of deep vein thrombosis or valvular incompetence is required and the pulse detection is difficult or impossible. It is first choice for screening and treatment follow up.
	The Doppler signal detected in normal arteries generally contains easily differentiated flow phases; first, louder with higher frequency (higher pitch) and next, with lower intensity and frequency (lower pitch). The first sound is reminiscent of a strong wind blowing; the other two reminiscent of a noise of smaller intensity in those arteries with a smaller degree of occlusion, while in arteries of a greater degree of occlusion (over 50%) the second phase fades and only the first phase, corresponding to heart contraction, is audible. A single-phase signal usually has a high frequency and is similar to wheezing. At, or immediately downstream of, the occlusion, the sound is composite. It consists of high frequencies, corresponding to the acceleration of flooding by occlusion with a superimposed booming tone, usually associated with disturbances of the flow upstream of the occlusion. In carotid arteries where flow resistances are much less than in lower limb arteries, after the first phase usually a continuous Doppler "noise" is audible, corresponding to the continuous flow in the diastolic phase. In atheromatously modified blood vessels signal frequency diminishes, the diastolic phase fades, diminishes or completely fades. oddechowego. It can successfully replace the stethoscope for measurements of blood pressure in patient with difficult to hear Korotkoff sounds. This application is especially important in detecting of peak systolic pressure in lower extremities with stenotic lesions and evaluation of ankle/brachial systolic pressure index (measured with cuffs and sphygmomanometer).. Sonomed Doppler is handy and easy to use. The unit design was though to simplify its use reducing to minimum controls - volume up/down and on/off switches. The front of the probe or patients skin should be covered with Ultrasound Gel in the way assuring good acoustic coupling. It's better to use more than less Ultrasound Gel. The automatic noise control reduces initial noise and strong signals from probe movements. The device is offered in a dedicated plastic suitcase. Standard package includes: the Doppler unit, ultrasonic transducer, battery charger, gel, User Manual, headphones..
