Tool Reviews

Blood pressure is an important indicator of human health. Mechanical devices provide accurate control of blood pressure, and the timely detection of deviations helps to avoid negative consequences.

How to choose a mechanical tonometer

The classic blood pressure monitor works on a simple principle, which makes it affordable and affordable. The tonometer operates mechanically, does not depend on electricity, so you can use the device anywhere.

1. When choosing, the emphasis is on workmanship. Carefully inspect all connections, cuff seams. A good model is made neatly and evenly, without any flaws.
2. Check the audibility of the stethoscope, make sure that the temples fit snugly, but do not cause discomfort.
3. Consider the pressure gauge: are the numbers clearly visible, is the arrow exactly at zero.
4. Try to pump up the pear, deflate the air.
5. Examine the characteristics of the device.

Important parameters

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

measurement range

The lower range of most products varies between 0-20. Such a mark is sufficient for any measurement. The upper limit of up to 180 is suitable for people under the age of 50 without chronic diseases. If there are pressure surges, choose a tonometer with a large value. The range reaches 300 mm. rt. Art.

Cuff size

The girth of the armlet in the models is divided into categories: large, enlarged, standard, children’s. A standard size is suitable for people with an average build. If the measurement technology is followed correctly, the error will be insignificant.

Stethoscope

A phonendoscope is almost always included in the package of the device. According to the design features, the stethoscope is built into the cuff or comes separately. A tonometer with a separate phonendoscope simplifies the work with the device.

Stethoscope design

The stethoscope head is made of plastic, aluminum or stainless steel. The larger the volume of connecting tubes, the better. They are made of rubber or vinyl, which do not transmit noise from the outside. The most comfortable length is 50-55 cm.

ear olives

They differ in hardness. Hard tips are made of plastic, soft tips are made of rubber or gel. Elastic olives fit snugly around the ears, taking the shape of the ear canal. This increases the comfort of measurement, eliminates external noise.

Secondary parameters

Price

Mechanical tonometers cost about the same. Therefore, it is not worth focusing on this indicator.

Product color

The sleeve is made in two versions: black or blue. Therefore, it is not necessary to expect bright colors. And this does not affect the operation of the device.
