The device for measurement of arterial pressure of Tensi

The tonometer is the special device used in medicine and in medical business in general. Its main function is measurement of arterial (blood) pressure of the patient.

The most important for a house tonometer is an accuracy of definition of results of measurement of pressure. The wrong indicators in its work or the slightest deviations can lead to emergence of considerable complications at patients with an idiopathic hypertensia.

What types of tonometers and what its characteristics should be considered exist, choosing the similar device for house use?

All tonometers existing today are divided into three look: mechanical manual, automatically and semi-automatic. The first, arisen from them, - mechanical. The mechanical tonometer puts on the cuff on a forearm, air shakes manually.

Arterial pressure is measured on blows of heart on an artery. The result is watched on the manometer. Mechanical tonometers have the advantages before automatic which are expressed first of all in the device price. The main lack of manual tonometers consists in high probability of their inaccuracy, more precisely than inaccuracy of the one who measures pressure. But on the other hand, behind mechanical tonometers the reliable reputation confirmed many years and people.

Automatic tonometers, are now used more manual, for the reasons of simplicity of their operation and high precision of the measured pressure. Besides, automatic tonometers can carry out several functions: to measure a blood pressure or pulse. Automatic tonometers it is possible to measure pressure upon a wrist, a shoulder or on a finger.

Automatic tonometers have a function of storing of results of measurement, all their indications in a digital form are stored in memory of the device. Getting a tonometer for house use it is better to stop the choice on automatic or semi-automatic.

They have a number of advantages over manual devices: use of automatic tonometers do not demand any physical efforts, on them easily and just to know exact pressure, equally well suit people of all age categories.
