Today, wearable devices have become standard, and their market share is relatively stable, whether it is a bracelet or a watch. The wave of prices that began in 2012 has undergone various reshuffles. Where will the next step in the wearables market go?

Under the judgment, the current development process from white-collar standard to medical-level monitoring.

The milestone in 2018 was Apple's release of iWatch with FDA-approved ECG detection, which allowed the entire dynamic ECG market to boil again.

After the listing of Huami, it has also made great efforts. Its AMAZFIT is the first CFDA-certified medical-grade wearable dynamic ECG recorder.

In the medical grade wearable device began to play the role of product screening and auxiliary diagnosis. For the four vital signs: body temperature, heart rate, blood pressure, respiratory rate have product breakthroughs, in addition to blood sugar, ECG, EEG, blood oxygen and other signs are also a battleground.

Especially in heart rate monitoring, wearable devices can monitor atrial fibrillation and other hard-to-find arrhythmias.

The current dynamic ECG monitoring mainly adopts two kinds of signal collection methods: ECG and PPG. The ECG is detected by bioelectricity. After capturing the bioelectric signal and then digitizing it, it can be converted into digital signal processing, and then the output can be accurately and detailed. Heart health information.

PPG refers to photoplethysmography (PhotoPlethysmoGraphy), or PPG for short, to monitor heart rate.

The principle is simple: the blood is red, reflecting red light and absorbing green light. PPG, on the other hand, obtains heart rate information by detecting the amount of blood circulating at the wrist at a specific time.

Another method is the difference in lead. A standard ECG requires 12 leads, 12-lead automatic ECG analysis system, and can perform 12-lead, 6-lead, 3+1 lead, 3-lead, long-term rhythm lead records;

Can be recorded in the conventional ECG, if abnormal heart rhythm is found, the 1 minute waveform record and extended record of the rhythm lead can be automatically completed.

Most of the dynamic ECG monitoring products are analog leads. Take the ECG of apple watch as an example, there is only one lead. Secondly, this lead is not a standard lead collected by standard methods, but after other methods are used to collect the signal, the software program calculates the graph that the doctor is used to see, which is the analog lead.

Recently, AliveCor announced the company's next direction: the introduction of a six-lead ECG compatible with smartphones. Perhaps one day wearable devices will also become medical monitoring products.

With medical grade wearables, you can start linking patients and doctors from the doctor's side. Combining a large amount of health data with diagnosis and rehabilitation will be the focus of the next phase!

The AMAZFIT-equipped Mi-Med Medical App released by Huami is actually such an application. How to turn a consumer medical grade bracelet into a "assist diagnostic tool"?

Mainly a lot of ECG ordinary people can not understand, and as a professional cardiac rehabilitation institution, providing professional data interpretation and advice behind the scenes, there will be a commercial charging model in the future.

Why cardiovascular disease has the highest mortality rate, because the two important aspects of early screening and rehabilitation are missing. Every day, 1,000 people are killed in China. Some of them have no history of heart disease, which is a healthy person in the eyes of everyone. For rehabilitation, postoperative cardiac rehabilitation can reduce postoperative mortality by 26% for heart patients.

In addition to online data integration and value mining, you can provide light consultation and Q&A services in the background. If there is a problem with the customer, he will be advised to go to the local medical institution to do a professional ECG monitoring.

After treatment, rehabilitation teaching can be provided so that patients can learn professional cardiac rehabilitation guidance at home.

These are not completed by traditional bracelets or watches, and can also be seen as the new value brought by technological advancement.

The bracelet and ECG will be further integrated. The main two forms are ECG stickers and smart watches, both domestic and foreign.

iRhythm pioneered SMD ECG monitoring products and is now the top three digital healthcare company in the US. After Apple introduced a smart watch with ECG, iRhythm also fell sharply. But from now on, the bracelet and ECG are beginning to combine.

iRhythm's products are available through prescription. When the monitoring session is over, the patient simply sends the device back and the stored data is uploaded to the iRhythm cloud-based server, using a proprietary AI algorithm to identify and analyze the heart rate market. The last report will be generated and provided to the patient's doctor within 24 hours.

In addition, Apple's new watches and algorithms are not designed to detect arrhythmias, which limits the overall function of the watch as an arrhythmia monitoring device.

Apple's mobile phones, watches and apps will undoubtedly appeal to young and wealthy consumers, but how Apple will evolve in helping people understand and manage their health remains to be seen.

Domestic Huami's AMAZFIT also launched the bracelet and ECG at the same time. The AMAZFIT wearable Holter recorder supports both the wristband measurement and the cheststick measurement.

The use of the bracelet is similar to that of the Apple Smart Watch. In the wristband measurement mode, the user only needs to wear the ECG recorder on the wrist, keep the arm horizontally raised, and the other hand presses the index finger to the metal button at the bottom of the screen. On the top, press and hold the button to start measuring. The result can be obtained in about 30 seconds.

After experiencing the bubble development of consumer-grade wearable devices, wearable products are now advancing to the medical level, especially the dynamic ECG monitoring equipment market has a new threshold, and new game rules are taking shape.

The follow-up will accelerate the accumulation of big data, and even smart wearable devices will be launched one after another. Real personal monitoring doctors may be ready to go.

The future will be the world of the Internet of Things, let us meet on November 19-21, 2019, and meet the 2019 (3rd) Global Internet of Things Conference - looking for thinkers!
