5 Mechanical tonometers: how to choose the characteristics, pros and cons

Blood pressure - an important indicator of health. Mechanical devices provide precise control of blood pressure and the timely identification of deviations to avoid negative consequences.

How to choose a mechanical tonometer

Classic instrument for measuring blood pressure works on the simple principle that ensures the availability and inexpensive cost. Tonometer operates mechanically, does not depend on electricity, so you can use the device anywhere.

1. When selecting the focus is on the quality of manufacturing. Carefully inspect all connections, cuff seams. A good model is made accurately and smoothly, without any flaws.
2. Check the audibility of the stethoscope, be sure that the shackle snug, but do not cause discomfort.
3. Consider gauge: clear whether the figures seen whether the arrow is exactly zero.
4. Try to pump the bulb, pull the air.
5. Learn the characteristics of the device.

important parameters

The design consists of a cuff worn on the shoulder, the air pump pears stethoscope. These elements are the main differences between devices.

measurement range

The lower range of most products varies between 0-20. Such markers enough for any measurement. The upper limit of 180 is suitable for people under the age of 50 years without chronic diseases. If there are pressure surges, choose a tonometer with great value. The range reaches the figure of 300 mm. Hg. Art.

The cuff size

Girth armlets models divided into categories: large, extended, standard, baby. People with an average physique fit a standard size. With proper compliance measurement technology error will be insignificant.

Stethoscope

Stethoscope almost always included in the instrument packaging. According to design features a stethoscope built into the cuff to or separate. Tonometer with separate stethoscope simplifies the work with the device.

design stethoscope

Stethoscope head is made of plastic, aluminum or stainless steel. The greater the volume of connecting tubes, the better. They are made of rubber or vinyl, that do not pass the noise from outside. The most convenient length of 50-55 cm.

ear olive

They differ in hardness. Hard tips are made of plastic, soft - made from rubber or gel. Elastic olive seal tightly to the ears, taking the form of the ear canal. This increases the measuring comfort and eliminates outside noise.

secondary options

cost of

Mechanical tonometers are about the same. Therefore, the emphasis on this indicator is not necessary.

coloring products

Armband is available in two versions: black or blue. Therefore, we should not expect bright colors. And the device is not affected.
