Millet watch blood glucose data through signal processing algorithms as well as artificial intelligence constructed by the user model **** the same calculation of blood glucose value. It is non-invasive blood glucose detection technology combines physics, optics, bioengineering, signal processing and artificial intelligence algorithms to measure the human body's ECC (electrocardiogram) and PPG (photoelectric volumetric pulse wave scanning notation) signals through a number of optical sensors with different wavelengths, and collects the data in a comprehensive manner with four different detection methods.
How does the blood glucose function on the oppo watch work?
You can measure blood glucose, blood glucose is the use of artificial intelligence technology, real-time monitoring of the human body's signs of data, every 2 hours out of the trend value, to be able to better determine the current blood glucose the existence of the risk of hidden danger.
Is the watch for blood sugar reliable
The principle of the watch for blood sugar is to infer the value of blood sugar through the composition of body fluids, and its data has a certain bias. For diabetic patients, doctors need to observe the changes in their condition and guide the use of medication based on their blood glucose values, and the deviation of blood glucose has a high chance of affecting the therapeutic effect, especially for some special thresholds, such as 3.9 millimoles per liter and 13.9 millimoles per liter. Blood glucose below 3.9 mmol/L means hypoglycemia, which may be life-threatening if glucose is not replenished in a timely manner, whereas above 13.9 mmol/L, there is a high chance of acute complications, which also need to be adjusted in a timely manner. The patient's blood glucose such as in the vicinity of the critical value, which requires blood glucose equipment must be accurate enough.
Currently, in addition to fingertip fast glucose meters, there are already minimally invasive continuous glucose monitors on the market that are medically certified for use for medical purposes. For non-invasive glucose monitoring devices, there are institutions at home and abroad that are researching, but there are many factors that affect the results, and there are no recognized results yet.
How Huawei watchgt2proecg monitors blood glucose
As an upgraded model of WATCHGT2Pro, Huawei WATCHGT2ProECG model has added the new ECG acquisition and vascular health research detection function, which is of great significance for people who are concerned about their health as well as those who have potential cardiovascular risks, and it is one of the few devices nowadays that can provide Perfect health management + sports guidance of the long-lasting smartwatch, in the same category of competitors, health and sports professional advantage is obvious. Its arrival makes Huawei's leading position in the health and sports watch segment once again higher.
Nowadays, almost all smartwatches support the heart rate monitoring function, but the speed of the heart rate can only be used as a general reference, and it is difficult to determine the signs through the heart rate for those users whose hearts have potential health risks. In addition, many people work at a fast pace and high pressure, neglecting medical checkups, so wearable smart devices that can provide professional ECG analysis at any time have become the rigid demand of this user group.
It is understood that the Huawei WATCHGT2ProECG model supports one-button measurements and quickly obtains a report of the results. Wearers only need to put their fingers on the electrodes on the right side of the watch, and it only takes half a minute to complete the ECG measurement and provide a professional analysis report, which records the current heart beat rhythm in detail, helping wearers to clearly understand the heart beat rhythm; they can also add symptoms on their own, such as shortness of breath, chest tightness, dizziness, etc., to record the current symptoms in detail, and to better understand the health status of their own heart.
As Huawei's first smart wearable device to pass the National Drug Administration (NMPA) Class II Medical Device Registration Certificate, it is based on a high-performance ECG sensor and brings professional ECG acquisition. Huawei WATCHGT2Pro ECG model watch also at the same time jointly with the "National Telemedicine and Internet" Medical Center is an authoritative national medical center, selected three hospitals professional physicians to provide artificial ECG interpretation services, give a report with the physician's signature, give ECG interpretation results to help the user early detection of the risk of arrhythmia. The ECG interpretation results will help users to detect the high risk of arrhythmia early and manage their heart health independently.
In addition, 301 Hospital initiated a heart health study based on Huawei's WATCHGT2ProECG high-performance ECG sensor, which helps users identify arrhythmia in a more refined way by recording the graphic of ECG signals in detail, discovering abnormal cardiac rhythms, such as atrial fibrillation and premature heartbeats (ventricular and atrial premature beats), and providing arrhythmia risk screening, personalized guidance, appointment booking, and integration of management services to help users discover arrhythmia at an early stage. It also provides arrhythmia risk screening, personalized guidance, appointment booking and integrated management services to help users identify high arrhythmia risks early and manage their heart health on their own.
This is especially important for people who often work late, smoke, drink alcohol, are obese, lack exercise, and experience occasional heart discomfort; people who suffer from high blood pressure, high blood sugar, coronary heart disease, sleep apnea syndrome, and other diseases; and patients who have already suffered from arrhythmia and have been diagnosed with related diseases.
In addition to a series of potential risks to the heart, today's atherosclerosis as the representative of vascular disease has also become one of the country's biggest health threats. Atherosclerosis is a non-inflammatory lesion of the arteries that can cause the arterial walls to thicken, harden, lose elasticity, narrow the lumen, and is often accompanied by sub-health. This latest watchGT2 watch from Huawei is required to use a third-party blood glucose meter and then read the data, it is not allowed to measure itself.
The Apple Watch is going to be fitted with an 'ECG'! A "touch" of both hands can be measured, blood pressure and blood sugar is not far away

These days, there may be a lot of partners have brushed to such a piece of news. AppleWatch's electrocardiogram function to come?
In a document released by the State Drug Administration (SDA), Apple received an approval for a "mobile ECG atrial fibrillation alert software".
While it's not explicitly stated in the document, basically everyone has guessed that it's talking about the AppleWatch's electrocardiogram (ECG) feature.
In fact, all three Apple Watches from the AppleWatch 4 generation onwards (except the SE) support this feature, but it's only open in some countries and regions, so what can you do with this feature? In the end, is it reliable? The future smart watch can even measure blood pressure, blood sugar? Jiguo Jun will give you partners to introduce the knowledge in this regard.
In fact, measuring heartbeat with watches and bracelets is not a new feature. AppleWatch, for example, measures heart rate by "light".
The heart rate is measured using the "Photovolumetric Profiling" (PPG) method, which simply means that the flow of blood is measured by light to determine the heart rate.
The blood is red and absorbs green light, which is emitted by the green LEDs on the watch, and the sensor determines blood flow by measuring how much green light is returned, which increases when the heart beats, so the heart rate is measured.
But the watch doesn't always emit green light to measure heart rate, it uses infrared light to measure heart rate every ten minutes or so, and green LEDs are used when infrared light is difficult to obtain accurate results.
So the watch is only detecting heart rate through "light," and you have to take it to measure something else, too. If you have to use it to measure something else, you might get a "reading" but of course, it's not very informative, like this "tachycardia" banana.
Measuring your heart rate can indicate how fast or slow it is, as well as detect arrhythmias.
And Apple Watches since the AppleWatch 4 (except the SE) have added ECG, or electrocardiogram, functionality.
To understand how it works, you need to know, first of all, the principle of ECG. Simply put, every time a heartbeat occurs, the depolarization of heart muscle cells causes a very small electrical change on the surface of the skin, and if two electrodes are placed on any two sides of the heart, then tiny voltage changes between the two electrodes can be recorded in the process, and can be displayed on ECG paper or a monitor.
People who have been to the hospital for an electrocardiogram know that a complete electrocardiogram requires multiple electrodes to be placed on the wrists, ankles, chest, etc. to measure the electrocardiogram, so why do you need to bring so many "sensors"?
In general, the standard ECG consists of "12 leads", the so-called 12 leads, that is, the electrodes attached to the body can form 12 groups of circuits, observed 12 groups of ECG, so that you need to place 10 electrodes on the body, can be from multiple directions to "observe" the heart.
Schematic diagram of the location of 12 leads and 10 electrodes
In addition to this, there are usually "3-lead" and "5-lead" electrocardiograms, which are used according to different needs.
AppleWatch's ECG function can only measure a "single-lead" ECG - that is, the left arm and the right arm form Lead I. When using the watch to measure an ECG, the left arm and the right arm can only measure one lead, and the right arm can only measure the left arm and the right arm. When using the watch to measure an ECG, you need to place the fingers of the hand not wearing the watch on the crown to form a loop.
Electrocardiogram measured by Geek with AppleWatch
If you put the AppleWatch in other positions of the body to measure the electrocardiogram, you can theoretically also get the results of Lead II and Lead III, and detect the heart from more perspectives, but this usage has not been officially corroborated by Apple, and so Apple will not be responsible for the other two usage However, there is experimental evidence that the results from this method are somewhat reliable.
Currently, the ECG function has been reviewed, but it has not yet been opened for use, and those who want to experience it will need to wait a little longer. Although some e-commerce platforms offer services to help open the function, there is a certain account security risk, so don't try it easily.
By using the watch to measure the electrocardiogram, you can detect atrial fibrillation to some extent. But be warned, it's not foolproof.
Lead I, just mentioned, observes mainly the high lateral wall of the heart, so it may be more difficult to detect problems in other parts of the heart by looking at the ECG from just this one angle.
Thus, AppleWatch is not suitable for people who already have heart disease to use for daily monitoring. Portable ECG testers on the market for hundreds of dollars have three leads (the equivalent of looking at the heart from multiple directions), and after all, the AppleWatch isn't a specialized thing for measuring ECGs.
A portable ECG monitoring device
But is the AppleWatch's ECG function completely useless? Not really, the fact that it has passed the certification of several countries and regions shows that it still has some reference value. Apple Watch can effectively detect heart problems such as atrial fibrillation by detecting the ECG, and there have been reports that someone saved his life because he found a heart problem by utilizing AppleWatch's ECG function and got timely treatment.
Foreign media reported that a woman's husband discovered atrial fibrillation through AppleWatch and was treated in time
A study published in the Journal of the American Medical Association (JAMA) in 2020 showed that smartwatches have a 90 percent accuracy rate in properly recording heart attacks. So what exactly is the proper use of these products?
If you're someone who suffers from a heart condition, then there's a simple thing you need to do - go to the doctor instead of relying on some watch. Taking your doctor's advice and buying a more specialized medical device is your only option.
If you're just a health-conscious person who pays attention to your body, then the smartwatches on the market are more appropriate, as they are like "insurance" that can detect possible heart health problems and give you early warning.
Many heart problems are hard to notice, and once they occur, the consequences can be serious. At this year's Euros, Denmark's core player Eriksen suddenly collapsed on his own during the game because of a sudden heart problem, but fortunately he was rescued in time and is now unharmed.
Eriksen posted a selfie on the social media platform
Of course, it's still important to remember to see a doctor in a timely manner if you have a problem, and not to rely on a tiny smartwatch, which at best can only remind you that you need to see a doctor! What else can the future AppleWatch do? Blood pressure or even blood sugar?
What other health features can AppleWatch have? An Apple patent gives a "heads up".
We usually need a process of inflation and deflation to measure blood pressure, which, if replicated on a smartwatch, would have a significant impact on the watch's size, battery life, and even appearance.
But an Apple patent titled "Blood Pressure Monitoring Using a Multi-Functional Wrist-Worn Device" shows that three sets of electrodes on a wrist-worn device can sense the pulsed electrical signals of the left ventricle's contraction, and then determine the value of the pressure based on the time of day.
The technology's bigger breakthrough is that it's simple and easy to monitor blood pressure on a continuous basis, and if it has the ability to do that, then all the home blood pressure devices on the market may be "out of business.
If the blood pressure measurement is not that great, then the blood glucose measurement function is more "god". Typically, blood glucose testing requires a blood draw, which is very troublesome and painful, especially for diabetics who need to monitor their blood glucose over a long period of time, which is really a nightmare.
Apple's patent on blood glucose monitoring shows that it uses "terahertz electromagnetic radiation" to "irradiate" blood vessels and measure absorption to detect blood glucose levels.
Schematic diagram of the patent for measuring blood glucose using terahertz electromagnetic radiation
In addition, the use of near-infrared light may also be able to monitor blood glucose, and the concentration of blood glucose affects the absorption of light as well as the optical path, which is currently being researched, and which is intended to be added to many smartwatches in addition to the AppleWatch.
But alas, blood pressure or glucose functionality may not be coming so soon. Readings of both measurements must be accurate, and if they are off by too much, they may affect a patient's control over the amount of medication he or she takes. Examples include ingesting too much insulin leading to hypoglycemia.
What does it look like so far for the next-generation AppleWatch, which is expected to be released this fall? In terms of appearance, it is predicted that it will probably adopt the square corner design of the iPhone 12 series, which one do you think looks better?
Long life, performance optimization will further reduce energy consumption, it is expected that the duration will be extended from the current 18 hours to about 20 hours, two days a charge is actually still a little difficult.
In terms of health features, it can be said that the current better is AppleWatch, and other manufacturers of smartwatches are also catching up. Which feature are the little ones looking forward to the most?
The watch face is able to capture the temperature of our wrists and then calculate it to arrive at the body temperature. Because of the epidemic, we need to measure the body temperature wherever we go, and carrying a thermometer with us is just too much trouble. I didn't realize that Huawei Watch was so thoughtful that it actually introduced a feature that can detect body temperature. I don't know if you still remember when Huawei's last watch was? In fact, that was already in 2017, and Huawei has not launched any new watch for four whole years since then.
So long ago, Huawei watch is finally coming with the latest Monhon system. Huawei has always emphasized that everything can be connected, let's say a lot of Huawei devices are able to control the home air conditioning, computer, lights and so on. It can also help us find the car when we are out and about, and even check the fuel level and mileage of the car. These features greatly facilitate our lives, and so powerful that it is the user can not help but marvel. In addition to this, the Watch3 has a lot of features that make it stand out to us.
Being able to support independent calls, the Huawei watch we used before this need to be able to call through the phone. It can also support dropshipping, checking maps, using Alipay and so on. Many third-party applications can be easily operated, completely realizing the smart life. In addition to being able to measure our body temperature anytime, anywhere, the watch is also able to monitor the user's sleep status, the risk of apnea, and so on, through the activity.
In this way, this watch now also has a guarantee for our health, it can simply do real-time monitoring. But the price of this watch is not cheap, after all, it has such a powerful strength, so expensive is no excuse for things. So we should still make a decision according to their own economic level, if the economy allows, absolutely should buy such a watch, both practical and wind.
