Non-invasive glucometer - what you need to know about these devices. Glucometers without pricking a finger New device for measuring sugar without pricking Czech Republic

We draw your attention!
The Glucowise device is a scientific development,
NOT mass-produced or sold in any country in the world!
Be careful!

The British company MediWise, which has successfully implemented several innovative projects in the field of health, announced the creation of its own version of a non-invasive glucometer. The device, called Glucowise, will be more accurate than its already presented analogues, since it is supposed to examine blood at the capillary level.

The monitoring system consists of:

directly from the Glucowise sensor;
a special application for a smartphone;
Smart Cloud is a cloud server that allows you to store and systematize the information received.

How does it all work?

The proposed method allows you to measure glucose concentration without a single puncture and blood sampling. And the analysis will take a maximum of 10 seconds. The GlucoWise meter is similar to the Abbott system, but does not have consumables. The basis of the Glucowise system is a special sensor that transmits high-frequency waves through an area of skin with a well-developed network of capillaries (the earlobe or the skin fold between the thumb and index finger is ideal). The opposite side of the device records the received signals and compares their characteristics with the original radio waves. Based on the measurement taken, the sugar level is calculated using a special algorithm.

To improve accuracy, the surface in contact with the skin is coated with non-composite films, which ensure sufficient sensitivity of the epidermis to radio waves during analysis. As a result, the error will be minimal, regardless of age or skin type.

Immediately after the test is completed, the result is displayed on the Glucowise screen. In the future, the information can be transferred to a smartphone or tablet to maintain statistics and track trends (if you have a special mobile application).

The creators of Glucowise plan to integrate the application with other mobile and online platforms used for self-monitoring of health.

Information collected by the meter can be uploaded directly to Smart Cloud. It is enough to connect the bloodless analyzer to a computer via a USB interface.

The American company Google, known to almost every modern person, has patented a smart glucose meter that is capable of analyzing blood glucose levels without piercing a finger with a needle. What's interesting is that if you think that this is a non-invasive blood sugar test, it is not.

Google proposes to solve the problem of disposable lancing lancets, which are often used repeatedly and are not always convenient to use. Why are traditional lancets not convenient? First of all, this is, of course, the problem of their “reusability”. This is not always hygienic, especially considering “combat” conditions, hospitals, countries with low living standards and sanitary standards. It doesn’t cost anything to mistakenly make 2 punctures on different people with one lancet - you yourself understand the consequences of this. Roche has partially solved this problem, which contains a drum of 6 lancets, in which you can select a new, unused lancet in the drum with one click, without the ability to use old lancets 2 times. Another problem is the sharpness of the puncture. Medical instruments, including lancets for diabetics, become very dull after repeated use, which is strongly felt, leading to painful punctures and non-healing fingertips. And the last disadvantage of standard finger pricks is the impossibility of accurately adjusting the amount of blood; there is always an extra drop of blood that must be mechanically removed from the finger. Or vice versa, there is not enough blood to measure, and we lose a precious test strip for the glucometer.

Google's development solves all these problems at once, including the problem of blood testing in areas remote from medical laboratories, and will also be very useful for patients with diabetes. Unlike a glucometer, the Google glucometer will not only be combined with a blood sampling device and a drum of test strips, but also with a smart watch. Just imagine, a glucometer in your watch! But the most interesting thing in this device there won't be needles, lancets and some sharp parts!

The device will use a capsule with compressed air and special microparticles to “pull” exactly as much blood as needed, sucking it into the glucometer. The drop itself will not form, the skin will practically not be injured, and safety and hygiene will always be 100%.

Google has been thinking about the problem of blood testing for a long time and is trying to make this procedure easier, like the life of all diabetics. The patent application doesn't give any hints as to when the device might be released, but it's clear that the possibility exists and the likelihood of seeing a blood glucose meter from Google is getting higher and higher every year. Let's hope and wait, but in the meantime you can explore the assortment of our online store. See you soon!

Non-invasive glucometer – measuring blood glucose levels without damaging the skin. Now a person with diabetes will not have to constantly prick their finger and spend a lot of money on purchasing test strips. It will be enough to buy the device once and use it for your pleasure. As practice shows, older people very rarely use glucometers. Have you ever wondered why? A package of test strips costs about 400 UAH on average. or 1200 rubles, not every pensioner can afford it. It would be nice to have a device that works without consumables.

At home, to measure sugar you need a glucometer, test strips and lancets. The finger is pricked, blood is applied to the test strip and after 5-10 seconds we get the result. Permanent damage to the skin of the finger is not only pain, but also the risk of complications, because wounds in diabetics do not heal so quickly. A non-invasive glucometer takes away all this pain for diabetics. It can run smoothly and with about 94% accuracy. Glucose measurement is carried out using various methods:

optical;
thermal;
electromagnetic;
ultrasonic

Pros of non-invasive glucose meters– you don’t need to constantly buy new test strips; you don’t need to prick your finger for testing. One of the disadvantages is that these devices are designed for type 2 diabetics. For type 1 diabetes, it is recommended to use regular glucometers from well-known manufacturers, for example or.

Review of non-invasive glucose meters

Gluco Track DF-F

A non-prick glucose meter made in Israel, which simultaneously uses three measurement technologies: electromagnetic, ultrasound and thermal examination. Thanks to this, the manufacturer solves the problem of inaccurate results. Clinical trials of the GlucoTrack DF-F device were carried out at Med. center named after Moshe Soroka. More than 6,000 measurements were taken there, the results were almost identical to traditional methods of measuring blood glucose.

This device is small in size, has a display that displays data and a clip sensor that is attached to the earlobe. GlucoTrack DF-F is charged using a USB port and can be synchronized with a computer. Three people can use the device at the same time, and each person must have their own individual sensor. The glucometer is sold in EU countries, and sales are planned in America in the near future.

Disadvantages of GlucoTrack DF-F– once every six months you need to change the sensor-clip, once a month you need to undergo recalibration (you can do it at home, all this takes about 30 minutes), a “mere mortal” cannot buy it, it is very expensive.

Symphony tCGM

A non-invasive glucose meter that measures blood sugar transdermally (through the skin). In order to correctly install the sensor and the device to show accurate results, you need to pre-treat the skin with a special device - Prelude SkinPrep System. It cuts off the top layer of skin. The procedure is painless; only a ball of keratinized cells 0.01 mm thick is removed. This is necessary to improve the thermal conductivity of the skin.

A sensor is attached to the prepared skin, which will take samples of the intercellular fluid and measure the level of glucose in the blood, without any painful punctures. The sensor does not cause any discomfort to a person. The device automatically measures blood glucose levels every 20 minutes. Research results are sent to your mobile phone.

Omelon B2

The design of the Omelon A-1 device has been improved. This is a unique non-invasive device that can simultaneously measure glucose levels without damaging the skin, blood pressure and pulse. The device was developed by the Omelon company together with scientists from the University. Bauman and the Russian Academy of Sciences. Manufacturer: Voronezh JSC "Electrosignal".

The official website describes the operating principle of the Omelon B2 glucometer. Scientists have identified a relationship between blood pressure, vascular tone and pulse with glucose levels. All the knowledge of scientists is embedded in this device. Omelon B2 is intended only for healthy people and patients with type 2 diabetes. The developers do not recommend using this device for type 1 diabetes.

Specifications

Device size 155x100x45 mm, weight 0.5 kg without power source.
Blood pressure measurement range is from 0 to 180 mm Hg. Art. for children and 20 – 280 mm Hg. Art. for adults.
Glucose is measured in the range from 2 to 18 mmol/l, the error is within 20%.

According to the documents, Omelon B2 is an automatic blood pressure meter. Nowhere does it say that this is a glucometer. The positive aspects are the measurement of glucose without pricking a finger, the negative aspects are the large dimensions and the accuracy of the results.

Information has appeared on the Internet that the British company MediWise is developing a non-invasive glucometer called Glucowise. Blood glucose levels are measured at the capillary level, without a single finger prick.

Working principle:

Glucowise will contain a special sensor that transmits high-frequency waves through a certain area of the skin (earlobe or skin fold between the thumb and index finger). The second sensor receives the signal and compares it with the original radio waves. Based on the algorithm, the blood glucose level will be calculated.

The analysis will take only 10 seconds. All measurement results can be transferred to a smartphone through a special application or Smart Cloud (cloud server).

Glucowise was planned to be put into mass production after clinical trials in 2018. It’s already 2019, but I haven’t heard anything about the glucometer, apparently something went wrong.

Be careful, the device has not been officially created and is not for sale. Fraudsters have created a website and are allegedly selling Glucowise, but in fact they are sending you an ordinary Chinese glucometer. Don't be fooled!

Minimally invasive blood glucose meters without finger prick

Freestyle Libre Flash

Freestyle Libre is a special continuous and continuous blood glucose monitoring system from Abbott. It consists of a sensor (analyzer) and a reader (a reading device with a screen where the results are displayed). The sensor is usually attached to the forearm using a special installation mechanism for 14 days; the installation process is almost painless.

To measure glucose, you no longer need to prick your finger or buy test strips or lancets. You can find out your sugar levels at any time, just bring the reader to the sensor and after 5 seconds. all indicators will be displayed on the screen. Instead of a reader, you can use your phone; to do this, you need to download a special application on Google Play.

Main advantages:

waterproof sensor;
invisibility;
continuous glucose monitoring;
minimally invasive.

Dexcom G6

Dexcom G6 is a new model of a system for monitoring blood glucose levels from an American manufacturer. It consists of a sensor, which is attached to the body, and a receiver (reading device). The minimally invasive glucometer can be used by adults and children over 2 years of age. The device can be integrated with an automatic insulin administration system ().

Compared to previous models, Dexcom G6 has a number of advantages:

the device is automatically calibrated at the factory, so the user does not need to prick his finger and set the initial glucose value;
the transmitter has become 30% thinner;
sensor operating time increased to 10 days;
installation of the device is carried out painlessly by pressing one button;
a warning has been added that is triggered 20 minutes before the blood sugar is expected to drop below 2.7 mmol/l;
measurement accuracy has increased;
taking paracetamol does not affect the reliability of the obtained values.

For the convenience of patients, there is a mobile application that replaces the receiver. You can download it from the App Store or Google Play.

If you have diabetes, it is important to measure your glucose concentration daily. To test, each time you need to pierce the skin and take a drop of blood for analysis. It is necessary to take measurements before and after each meal, which is very tiring and painful, the puncture site does not heal well, and a callus often appears. Many patients reduce the collection of biomaterial to 2 times per day, which worsens the control of sugar levels and often causes complications.

Non-invasive glucometers without pricking a finger are a modern development to make the life of diabetics easier. Finally, you can forget about the discomfort and the constant purchase of test strips for analysis. Innovative glucose meters are more expensive, but the ability to measure sugar values at any time, even 10-15 times a day, quickly, comfortably, without the risk of infection and pain, is worth the money spent.

What kind of device is this

Modern glucometers use several indicators to determine glucose levels; blood is not needed for testing. High-tech new products additionally show the concentration of cholesterol, which allows you to quickly recognize the likelihood of a stroke or heart attack.

Original devices are divided into several categories based on the type of information reading:

some names are similar to a tonometer: they measure pulse and pressure, then convert the results into ;
there are devices that assess the condition of the skin: the patient needs to apply a small device to the body, and after a few seconds the required values will appear on the mini-monitor;
An interesting option is the Israeli development of Gluco Track. The patient attaches a small clip to the earlobe, which acts as a sensor. The combination of several measurement parameters and the latest technologies allows us to achieve an accuracy of 92-93%;
a glucometer implanted under the skin. The latest development allows you to use the mini-device for a year without replacement. An external receiver provides sugar values at any time upon patient request;
There are models in which developers use the spectroscopy method of a certain combination of scattered light. The diabetic will receive the data on his mobile phone via Bluetooth;
sensor devices use modern programs, like computer systems. Automatic data processing allows you to get a fairly accurate result at any time. Compatibility with Android ensures high processing speed.

Measurement results

Many diabetics are interested in how accurate the results of studies without blood sampling are. Minimally invasive glucometers evaluate several parameters; test results are considered reliable at 92% or more.

By measuring their sugar levels daily, diabetics learn to plan an optimal diet to avoid sudden fluctuations in glucose levels. It is important to evaluate indicators before meals and remember the need to test after meals. If you follow the instructions exactly, the values will be quite accurate.

To avoid unpleasant consequences, you need to remember about, and, the need to sharply limit “simple” carbohydrates. With a responsible approach to treatment, even small deviations in results when using non-invasive glucose meters will not be dangerous.

Price

The cost of modern devices for monitoring sugar levels without pricking a finger is higher than traditional devices. The approximate price of the models is from 6 to 12 thousand rubles.

Despite the high cost, doctors advise purchasing a device to use a non-invasive technique. Patients quickly feel the difference when using traditional and modern blood glucose meters.

No pain and nervousness, the ability to quickly obtain the necessary data at any time, carrying out tests without the risk of infection, no need to constantly purchase test strips - these are the undeniable advantages of the latest generation devices. If patients have poor blood clotting, they should definitely buy a safe model of the device.

Non-invasive glucometers, which do not require pricking a finger and taking blood for testing, are a new word in diabetology. Sugar levels are measured quickly, without pain and discomfort, at a convenient time, 7-10 or more times a day, depending on the patient’s condition. The optimal device model is selected by a consultant at the Medtekhnika salon. First, a diabetic should consult an endocrinologist.
