Rating of the best glucometers without piercing

For diabetic patients, accuracy and speed of measurement are very important. Devices for household use use different technologies and have their own disadvantages and advantages. The following is a rating of the leading non-invasive glucose meters for measuring blood sugar without needling.

Glucose plus pressure: Omelon B-2

The innovative technology was developed by Russian scientists. The operation of the device is based on the principle of dependence of vascular and muscle tone on glucose levels. Omelon B-2 (the name of the non-invasive glucometer) measures the pulse wave several times, then it switches to pressure, vascular tone and analyzes the blood sugar level. The high percentage of agreement between the indicators and laboratory test data made it possible to launch the innovative tonometer-glucometer into production. There are reviews, albeit few. Pros of a glucometer:

• no need to buy consumables (compensation for the high cost of the device itself);
• painless examinations, no contact with blood;
• insignificant difference with the results of laboratory tests;
• the ability to check not only sugar, but also blood pressure and pulse;
• automatic shutdown a couple of minutes after the last measurements are displayed on the display.

The power source of the non-invasive glucometer is standard AA batteries. The dimensions are above average - the device will not fit into your pocket. The warranty is only 2 years.

Important! The correctness of the readings obtained depends on compliance with the requirements for the procedure for measuring pressure. If the cuff does not fit the circumference of the arm, the patient becomes nervous and twitches during the test, and the result may be incorrect.

With the non-invasive glucometer Omelon V-2, you can immediately measure your blood pressure.
The price of the device is about 9,000 rubles. It is advisable to make purchases from authorized dealers.
