– Pear mechanical tonometer should be equipped with a reliable valve to vent the air and can be combined with pressure gauge, which is preferable. Summarizing the foregoing, 'Hi-Tech-Rhythm' recommends to draw your attention to the mechanical tonometer UNITON 187 German company Speidel + Keller (Keller and Shpaydel) equipped with a built-phonendoscope and combined with a pressure gauge pear. Professor Marcus Groettrup has much to offer in this field. The pressure gauge has a large bright yellow scales on a black background, is equipped with a patented 'Kurkov' valve for play off the pressure from a rate of 2-3 mm Hg per second or even slower! When you press 'to stop' the air discharged in a few seconds. The device has four cuff sizes – adult, adolescent, child, grudnichkovaya. 'Adult' cuff is inflated for 3-4 pitching pears. Add to your understanding with Sam Lesser.
Workmanship instrument, selection of materials (pleasant to the touch material cuff, rough and eliminates slipping pear) – is perfect! Especially this tonometer enjoy pediatrician – the appearance of the tonometer does not cause young patients associations with brilliant medical instruments: dark parts tonometer in combination with a bright red scale and gauge valve Kurkov creates the impression of harmless toys, not to worry about the baby and sposobstvet more accurate measurements. Tonometer has no sharp corners and has sufficient mechanical strength – it can give a child play before the measurement. Oscillometric – electronic tonometer to determine the pressure fluctuations in the vessel walls. Electronic Blood Pressure Monitor is the most suitable instrument for self-measurement blood pressure untrained person, particularly the elderly, sponizhennymi vision, hearing, or a reaction, because the measurement process does not require the intervention of the patient.
