The blood sugar data of Xiaomi watch is calculated by signal processing algorithm and user model constructed by artificial intelligence. Non-invasive blood glucose detection technology combines physics, optics, bioengineering, signal processing and artificial intelligence algorithms. The ECG (ECC) and PPG (Photoelectric Volume Pulse Wave Scanning) signals of human body were measured by several groups of optical sensors with different bands, and the data were collected by four different detection methods.
How to use the blood sugar function of oppo watch?
Can measure blood sugar, blood sugar is the use of artificial intelligence technology, real-time monitoring of human body signs data, every 2 hours issued a trend value, can better judge the current risk of blood sugar.
Is the watch for measuring blood sugar reliable?
The principle of the watch for measuring blood sugar is to infer the blood sugar value from the body fluid composition, and its data has some deviation. For diabetic patients, doctors need to observe the changes of their condition and guide medication according to their blood sugar level. There is a great chance that the blood sugar deviation will affect the therapeutic effect, especially some special critical values, such as 3.9 mmol/L and13.9 mmol/L. If the blood sugar is lower than 3.9 mmol/L, it means hypoglycemia, and if glucose is not supplemented in time, it may be life-threatening. If it exceeds 13.9 mmol/L, the probability of acute complications is very high and needs to be adjusted in time. If the patient's blood sugar is near the critical value, it is required that the blood sugar equipment must be accurate enough.
At present, in addition to the fingertip rapid blood glucose meter, there are already minimally invasive continuous blood glucose meters on the market, which have obtained relevant medical certification and can be used for medical purposes. Non-invasive blood glucose monitoring equipment has been studied by institutions at home and abroad, but there are many factors affecting the results, and there is no recognized result yet.
How does Huawei watchgt2proecg monitor blood sugar?
As an upgraded version of WATCHGT2Pro, the new ECG acquisition and vascular health research and detection functions of Huawei Watch GT 2 Pro CG are of great significance to people who are concerned about health and have potential cardiovascular risks. It is one of the few long-life smart watches that can provide perfect health management and exercise guidance. Among competing products of the same kind, the professional advantage of healthy exercise is obvious. Its arrival once again boosted Huawei's leading position in the segmentation of healthy sports watches.
At present, almost all smart watches support the function of heart rate monitoring, but the speed of heart rate can only be used as a general reference. For those users whose heart has potential health risks, it is difficult to judge symptoms by heart rate. In addition, many people have fast working pace, high pressure and neglect physical examination, so wearable smart devices that can provide professional ECG analysis at any time have become the rigid demand of these users.
It is understood that Huawei WATCHGT2ProECG supports one-click measurement and quickly obtains the result report. The wearer only needs to put his finger on the electrode on the right side of the watch, and it takes only half a minute to complete the ECG measurement, and provide a professional analysis report to record the current heartbeat rhythm in detail to help the wearer clearly understand the heartbeat rhythm; You can also add symptoms independently, such as shortness of breath, chest tightness and dizziness. And record the current symptoms in detail in order to better understand your heart health.
As Huawei's first smart wearable device that has passed the second-class medical device registration certificate of National Medical Products Administration (NMPA), it is based on high-performance ECG sensors and brings professional ECG acquisition function. Huawei WATCHGT2ProECG Watch is also the authoritative national medical center of the United Nations National Telemedicine and Internet Medical Center. Select professional doctors in 3A hospitals to provide artificial ECG interpretation services, and give reports with doctors' signatures, giving ECG interpretation results, so as to help users find the high risk of arrhythmia early and manage their own heart health.
In addition, 30 1 hospital has carried out the heart health research based on Huawei WATCHGT2ProECG high-performance ECG sensor. By recording ECG signals in detail, we can find abnormal cardiac rhythms such as atrial fibrillation and premature beats (ventricular premature beats, atrial premature beats), help users identify arrhythmia more accurately, provide arrhythmia risk screening, personalized guidance, appointment for medical treatment and comprehensive management services, and help users find high risk of arrhythmia as early as possible and manage their heart health independently.
Especially for people who often work overtime and stay up late, smoke and drink, are obese, lack of exercise, and occasionally have heart discomfort; Patients with hypertension, hyperglycemia, coronary heart disease, sleep apnea syndrome and other diseases; It has important reference value for the diagnosis of arrhythmia and related diseases.
Besides a series of potential risks to the heart, vascular diseases such as arteriosclerosis have become one of the biggest health threats to China people. Atherosclerosis is a non-inflammatory disease of arteries, which can thicken and harden the arterial wall, lose elasticity and narrow the lumen, often accompanied by sub-health. Huawei's latest watchGT2 watch needs to use a third-party blood glucose meter and then read the data. It is immeasurable in itself.
Apple watch should be equipped with "ECG"! Touching hands can measure blood pressure and blood sugar.

Many friends may have brushed such a news these days. Is the ECG function of AppleWatch coming? ! # Highlights of digital technology #
According to the documents issued by the State Administration of Medical Products, Apple has obtained the approval of the "Mobile ECG AF Prompting Software".
Although it is not clearly stated in the document, basically everyone guessed that this is the electrocardiogram (ECG) function of AppleWatch.
In fact, three Apple Watch 4Es (except SE) starting from the 4th generation of Apple Watch all support this function, only in some countries and regions. What can this function do? Is it reliable? Future smart watches can even measure blood pressure and blood sugar? ! Ji will introduce this knowledge to your friends.
In fact, measuring the heartbeat with a watch or bracelet is not a new function. Take AppleWatch as an example, measuring heart rate depends on "light".
Use the "light volume description method" (PPG)-in short, this method measures blood flow by light, so as to judge the heartbeat.
Blood is red and absorbs green light. The green LED light on the watch glows green. The sensor judges blood flow by measuring the amount of green light returned. When the heart beats, the blood flow will increase accordingly, so the heart rate is measured.
However, watches don't always emit green light to measure heart rate. More commonly, they measure their heart rate with infrared rays every ten minutes or so. When infrared light is difficult to obtain more accurate results, green LED will be used.
So the watch only measures the heart rate through "light". You have to use it to measure something else, and there may be a "reading". Of course there is no reference value, such as this "tachycardia" banana.
By measuring heart rate, we can prompt the speed of heart rate and detect arrhythmia.
AppleWatch4(SE has added ECG since AppleWatch4 (except SE), that is, ECG function.
To understand its working principle, we must first know the principle of ECG. Simply put, every time the heart beats, the depolarization of myocardial cells will cause tiny electrical changes on the skin surface. If two electrodes are placed on both sides of the heart, during this process, the slight voltage change between the two electrodes can be recorded and displayed on ECG paper or monitor.
Friends who have been to the hospital for ECG know that a complete ECG needs to place multiple electrodes on the wrist, ankle, chest and other places to measure ECG. Why do you need so many "sensors"?
Generally speaking, the standard electrocardiogram consists of "lead 12". The so-called lead 12 means that the electrodes attached to the body can form 12 sets of circuits and can observe 12 sets of electrocardiogram, so it is necessary to place 10 electrodes on the body to "observe" the heart from multiple directions.
Schematic diagram of the position of lead 12 and electrode 10.
In addition, there are usually "3-lead" and "5-lead" electrocardiographs, which are used according to different requirements.
However, the ECG function of AppleWatch can only measure "single lead" ECG, that is, lead I composed of left arm and right arm. When using a watch to measure ECG, it is necessary to put the fingers of the hand without the watch on the crown to form a ring.
Ji used AppleWatch to measure the electrocardiogram.
If you put AppleWatch on other parts of the body to measure ECG, you can theoretically get the results of lead II and lead III detecting the heart from more angles, but this usage has not been officially confirmed by Apple, so Apple will not be responsible for the results of the other two usages, but experiments prove that the results obtained by this method are reliable.
At present, although the ECG function has been audited, it has not been opened for use. Friends who want to experience still need to wait. Although some e-commerce platforms provide services to help open this function, there are certain account security risks, so it is better not to try it easily.
The occurrence of atrial fibrillation can be found to some extent by measuring ECG with a watch. However, it must be noted that it is not omnipotent.
The lead I just mentioned is mainly to observe the high side wall of the heart. Therefore, when there is a problem in other parts of the heart, it may be difficult to find the problem only from this angle.
Therefore, AppleWatch is not suitable for people who already have heart disease for daily monitoring. Hundreds of portable ECG detectors on the market are all three leads (equivalent to observing the heart from multiple directions). After all, there is a specialization in the industry, and AppleWatch is not specially used to measure ECG.

But is the ECG function of AppleWatch completely useless? No, it can pass the certification of many countries and regions, which shows that it still has certain reference value. AppleWatch can effectively detect heart problems such as atrial fibrillation by detecting ECG. It is also reported that some people use the ECG function of Apple Watch to find heart problems and treat them in time, saving lives.
Foreign media reported that a woman's husband found atrial fibrillation through AppleWatch and treated it in time.
According to a study published by JAMA)2020, the accuracy of smart watches in correctly recording heart attacks is 90%. So, what is the correct usage of this kind of products?
If you are a person with heart disease, what you need to do is simple-see a doctor, not rely on a watch. It is your only choice to follow the doctor's advice and buy more professional medical equipment.
And if you are just a person with high health awareness and always pay attention to your health, then smart watches on the market are more suitable. Such products are like "insurance", which can find your possible heart health problems with a certain probability and give you an early warning.
Many heart problems are difficult to attract people's attention at ordinary times, and once they happen, the consequences are also very serious. In this year's European Cup, Eriksson, the core player of the Danish team, suddenly fell to the ground during the game because of a sudden heart problem. Fortunately, the rescue was timely, and now it is no big deal.
Eriksson posted a selfie on social platforms.
Of course, remember to see a doctor in time if you have any questions. Don't rely on a small smart watch. It can only remind you that you have to see a doctor! What else can AppleWatch do in the future? Blood pressure or even blood sugar?
What other health functions can AppleWatch have? One of Apple's patents is eye-catching.
Usually we need a process of inflation and deflation when measuring blood pressure. If copied to a smart watch, it will have a great impact on the size, battery life and even appearance of the watch.
However, an Apple patent titled "Monitoring Blood Pressure with Multifunctional Wrist-worn Device" shows that only three groups of electrodes on the wrist-worn device can sense the pulse electrical signal of left ventricular contraction and determine the value of blood pressure based on time.
The greater breakthrough of this technology is that it can continuously monitor blood pressure simply and conveniently. If you have the ability of continuous monitoring, all household sphygmomanometers on the market may be "unemployed".
If measuring blood pressure is not so powerful, then the function of measuring blood sugar is even more "divine". Generally speaking, measuring blood sugar is very troublesome and painful, especially for diabetic patients who need to monitor blood sugar for a long time. This is really a nightmare.
Apple's patent on blood sugar monitoring shows that "terahertz electromagnetic radiation" is used to "irradiate" blood vessels, and the blood sugar value is detected by measuring absorption.

In addition, near-infrared light can also be used to monitor the blood sugar value, and the blood sugar concentration will affect the light absorption and light path. At present, related research is also in progress, and many smart watches besides AppleWatch also intend to add related functions.
But unfortunately, blood pressure or blood sugar function may not come so quickly. The readings of these two measured values must be accurate, and if the deviation is too large, it may affect the patient's control of drug dosage. For example, excessive intake of insulin leads to hypoglycemia.
At present, what changes are expected in the new generation of AppleWatch released this fall? In terms of appearance, the prediction may adopt the square corner design of iPhone 12 series. Which do friends think is better?
In terms of battery life, performance optimization will further reduce energy consumption. It is estimated that the battery life will be extended from the current 18 hours to about 20 hours. It's still a little difficult to charge every two days.
In terms of health functions, it can be said that AppleWatch is doing better at present, and smart watches from other manufacturers are also catching up. What function do friends expect most?
The surface of the watch can collect the temperature of our wrists and then calculate the temperature. Because of the epidemic, we have to take our temperature everywhere, so it's too much trouble to take a thermometer with us. I didn't expect Huawei watches to be so intimate that they actually introduced the function of detecting body temperature. I wonder if you still remember when Huawei's last watch was? In fact, it was 20 17 years, and in the following four years, Huawei did not launch any new watches.
After such a long time, Huawei watches are finally equipped with the latest Meng Hong system. Huawei has always focused on everything that can be connected. For example, many Huawei devices can control home air conditioners, computers, lights and so on. Going out can also help us find a car, and even check the amount of oil and mileage in the car. These functions greatly facilitate our lives, and users can't help but sigh that the functions are so powerful. In addition, this Watch3 has many features that make us shine.
For example, we can support independent calls. Before that, all Huawei watches we used needed to talk through mobile phones. You can also support Didi Chuxing, query maps, use Alipay and so on. Many third-party applications can be easily operated and smart life can be fully realized. In addition to measuring our body temperature anytime and anywhere, this watch can also monitor the user's sleep state during sleep, whether there is a risk of apnea and so on.
In this way, now this watch is also guaranteed for our health and can be monitored in real time. However, the price of this watch is not cheap. After all, it has such a strong strength, and such an expensive price is understandable. So everyone should make a decision according to their own economic level. If the economy permits, they should definitely buy such a watch, which is both practical and fashionable.
