The Chinese portable/home medical electronics market is growing rapidly and steadily thanks to the promotion of the Chinese government's new medical reform and the people's emphasis on health care, as well as the different characteristics of the home and medical markets.
In the next three years, the annual compound growth rate of China's portable/home medical electronics market will be greatly improved. According to market data, the market will expand rapidly from 8 billion yuan in 2006 to 28 billion yuan in 2011.
“And the market test proves that China’s portable medical electronics market has strong anti-risk ability, because the entire portable medical electronics market needs to face the Chinese domestic market, which is basically not affected by the financial crisis. In addition, the Chinese market is in the popularization stage. The market demand is strong, and the Chinese people's health awareness is constantly improving. Zhou Wensheng, senior business manager of ADI's Asia Pacific medical business, pointed out.
Like ADI, semiconductor manufacturers around the world are paying the most attention to China's portable/home medical electronics market. The future vision is a handful of people, not a portable medical device, which is a more attractive market than the mobile phone market. After many European and American companies have lost the huge market of Chinese mobile phones, portable/home medical electronics will be one of the biggest battlefields they have to defend. “The demand for portable medical devices in China and the global market is huge, and China is bound to become one of the largest medical electronics producers and markets,†said Fan Xujin, chief product marketing engineer at Microchip Medical Products.
Several portable medical devices with great potential
The pattern of China's healthcare industry is changing, which has spawned a larger market for portable medical devices. “In recent years, the pattern of the medical industry has changed from treatment to health care. Therefore, we predict that blood pressure monitors, blood glucose meters, low-cost heart rate monitors, etc. will be the hottest medical products in the future, and will be the most common among all families. Equipment," He Yingwei, marketing manager of Freescale Semiconductor Industry, predicted.
Zhou Wensheng of ADI added: "In addition, some ventilators and ECG monitors that can be used in home or small community hospitals will inevitably have more and more market demand. Some were originally only used in hospitals. Products such as electrocardiograms will also go into the family. In addition, some forward-looking household products will be developed one after another." For example, he said that today's cardiovascular disease is very lethal to humans, so ECG (ECG) It may become an indicator that we need to monitor every day. Moreover, some forward-looking techniques are added to the ECG device, such as the use of an acceleration sensor to monitor the patient's movements to help the doctor determine the patient's ECG status under certain conditions of exercise. Sometimes, adding MEMS to an electrocardiogram (ECG) also monitors abnormal patient conditions, such as a patient's fall, so that doctors and patient guardians can detect these emergencies in a timely manner.
Component trends to meet medical needs
The trend toward portability requires medical electronics to be small, low power, low cost, and easy to use. This puts new requirements on component suppliers. “Overall, the two most critical factors for portable medical design are low power consumption and high integration. Of course, different portable medical electronic applications such as portable ECG/blood glucose meters or sphygmomanometers are based on power consumption and integration. Depending on the degree, the specific specifications will also be different. But in any case, power consumption and integration are the key to design time. TI Yong, manager of MSP430 business unit in China, pointed out.
SoCs that integrate numerous digital and analog functions are the preferred platforms for portable medical devices. Each vendor is undergoing a high degree of integration. “In some mid- to low-end medical products, the current trend is to use dedicated SoC products to minimize product size and cost. As a result, some of the existing analog components such as ADCs, op amps and regulators will be Embedded in the MCU, and Freescale has the technical strength to develop such products." He Yingwei said.
However, Fan Xujin of Microchip pointed out that not all analog components are suitable for integration. He analyzed: "Medical electronics have different types of sensors, controls, and interfaces that require signal conditioning, all of which require analog components such as ADCs and operational amplifiers. Almost all Microchip PIC microcontrollers, from 8-bit to 32-bit series, are It has an integrated ADC as a standard function. However, due to higher performance requirements, not all applications can use integrated solutions. Independent high-resolution ADCs and high-precision operational amplifiers are still important for portable medical devices."
Gordon Hands, Lattice's director of marketing for low-density and mixed-signal solutions, emphasizes the need for portable medical devices in terms of cost: the main requirements for the portable/home medical market are the same as we have seen in the consumer electronics market. It is crucial to reduce the component price to less than $1 and reduce the power consumption to around 10uW. It's also important to have the flexibility and solutions that help get your product to market quickly. Few portable/home medical device designers can enjoy a design cycle of more than 12 months, just like designing an ASIC. (Midi Medical Network)
