Glucometer. User feedback and basic principle of operation

A glucometer is a device whose main purpose is to determine the amount of glucose that is contained in the blood and cerebrospinal fluid. It is used to control the level of sugar in patients with diabetes. With this pathology there is a violation of the endocrine function. The consequence of this process is a decrease in the production of a hormone (insulin), which plays a major role in the processing and assimilation of glucose by the body, as a result of which its large amount enters the bloodstream.

Glucometer, reviews of which indicate the possibility of timely detection of abnormalities, allows you to timely assign the patient the necessary treatment for him. The device can be used at different frequencies, usually two or three times per day.

The chemical meter of the glucometer, whose reviews indicate some difficulty in its use, is based on the principle of staining special test strips. Special reagents applied to them are able to change their color depending on the amount of glucose contained in the blood. Chemical devices are the first development of devices of this type. Their testimony is dependent on many external factors and has a large error.

Electrochemical device glucometer, the reviews of which note a small error in its measurement, refers to the devices of the new generation. When it is used, the blood drop interacts with the reagent of the test strip and the level of electric current that appears as a result of glucose oxidation is read. This type of instrument is very convenient to use. The bulk of devices intended for measuring sugar in polyclinics are electrochemical.

There are glucometers, the principle of which is based on coulometry. They summarize the amount of the total charge that occurs when a small amount of blood interacts with the test element. This principle of operation is used in home portable devices.

The non-contact Raman glucometer, which experts say is promising for its use, is currently under development. The device functions using a laser beam scanning laser. Occurring in this case in the body of the patient certain biochemical processes are fixed by the device.

A non-invasive glucometer is the most simple and convenient to use device. It was invented by the Ukrainian scientist from Uzhgorod Petro Bobonich. The device is based on infrared radiation. A special clip is attached to the patient's ear. After the luminescence of the lobe with infrared rays, the results are displayed on the controller. The blood test is done without piercing your fingers and constantly updating the test strips, which requires a regular glucometer. Non-invasive device type is the most sparing for the patient and requires only periodic replacement of batteries.
