Zhongwei Lai Kang Technology Development (Beijing) Co., Ltd., an international leading service provider, operator and equipment manufacturer of remote health management services, the International Emergency Rescue Center of the Chinese Ministry of Health and the China Health Care Association The only authorized executive agency of "Monitoring Network System". The popular Dr. Xin remote ECG monitor (health mobile phone) is the main product of Zhongwei Lai Kang. At present, this product has real-time ECG monitoring and blood pressure, blood sugar, blood lipid and exercise data uploading and management functions. New products based on the AD8232 analog front end of the ADI single-lead heart rate monitor are introduced.
As a portable ECG monitoring device that integrates smart phone functions, users always put forward higher requirements for standby time and size, and at the same time hope to test ECG waveforms more accurately, with stronger anti-interference ability and higher reliability. And the lowest possible price. The introduction of AD8232, the analog front end of the ADI single-lead heart rate monitor, provides an opportunity for new products of the "Dr. Heart" series of remote ECG monitors to better meet these characteristics. The "Heartbeat" remote ECG monitor based on the design and implementation of AD8232 It has a smaller size and longer standby time, and the ECG waveform is more accurate. At the same time, the high integration of AD8232 greatly reduces the number of components and BOM cost, and has stronger anti-interference ability and higher reliability. Meng Yu, CEO of Zhongwei Lai Kang, said: "Zhong Wei Lai Kang's latest 'Dr. Heart' remote ECG monitor has selected ADI's single-lead ECG analog front-end chip AD8232, which has achieved superior performance compared to the previous separation scheme. The size, power consumption and cost are greatly reduced. "
Dr. Tuxin Remote Intelligent ECG Monitor (Health Phone)
As a smart phone with professional medical monitoring and remote diagnosis functions, the "Dr. Heart" remote ECG monitor provides not only ECG monitoring, blood glucose / blood pressure monitoring functions, but also many mainstream functions of current smart phones. ——4.3-inch display, dual cameras, Bluetooth 3.0, WIFI wireless Internet access, FM radio ... Such rich functional integration will undoubtedly bring great challenges to designers to achieve a smaller size, longer standby time, and more stable performance. Based on the AD8232 single-lead heart rate monitor analog front end with the lowest power consumption and the smallest size in the industry, the new product of "Dr. Heart" effectively overcomes these technical challenges and provides Zhongwei Lai Kang users with more outstanding product features.
The AD8232 is integrated in a compact 4mm & TImes; 4mm LFCSP package, and also integrates signal conditioning circuit, lead drop detection, right leg drive, fast recovery and other functions. Therefore, compared with previous discrete solutions, the AD8232 chip only needs to add a small number of passive components to achieve the heart rate monitoring function, and the analog front-end circuit size is reduced by more than 50%. Based on these characteristics, as well as Zhongwei Lai Kang's excellent product system design capabilities, the latest "Dr. Heart" remote ECG monitor has achieved higher heart rate monitoring performance under the condition of further reduction in volume. In addition, these features also make the product design more flexible-you can choose a two-electrode or three-electrode system, you can flexibly set the bandwidth and gain of the link, you can freely choose the AC or DC lead off detection method, power saving mode, etc. Wait. Therefore, Zhongwei Lai Kang is more flexible in realizing the product design of "Dr. Xin", and it is more convenient to derive more serialized products, and shorten the time to market.

At present, smartphones are generally criticized by users for high power consumption and low standby time, and the latest "Doctor Heart" remote ECG health mobile phone can achieve 220 hours of long standby! As a heart rate monitor product that also has a smartphone communication function, its heart rate monitor function module has a great influence on the overall power consumption characteristics of "Dr. Heart". The AD8232 ultra-low operating power consumption and direct battery power supply make it easy to achieve the strict power budget of 180uA (typical value) operating power supply current when designing the "Dr. Heart" remote ECG monitor of Zhongwei Lai Kang. Shutdown function can extend battery life; using a flexible operating voltage range of 2.0V to 3.6V, can be directly powered by the battery, without the need for a power converter, saving power loss caused by power conversion.
As a leading global provider of high-performance signal processing solutions and a long-term partner in the patient care industry, ADI has extensive cooperation with major medical device manufacturers around the world to provide them with leading product solutions. Similarly, ADI has also carried out in-depth cooperation with Zhongwei Lai Kang. It has established good cooperation and communication channels in both new product planning, program demonstration and market information sharing. ADI will work on analog mixed signal chain products and microprocessors. Products and other fields provide maximum support.
