Medical electronics: ultra low-power portable medical electronics applications

In April of this year, China's new health reform programme launched.

In the new health reform programme, the Chinese Government planned for 2009-2011 three years invested $ 8500, used for primary health care system, basic public health services gradually Equalization and other five key reforms. Moreover, the new health reform could become the portable medical electronics market and rapid growth of the catalyst. Electronic sphygmomanometer, Oximeter, cardiac monitor, such as representatives of the household, portable medical electronics has become a daily health monitoring of critical equipment. According to market research firm CCID consulting, 2009, 2011, China portable medical electronics market CAGR of more than 30%, 2011 market will expand to $ 28 billion. At the same time, portable medical electronics in the past few years showing a miniaturized and design simplicity, smaller, lighter weight, low power consumption, with wireless connectivity and network medical information sharing, and other trends.

NXP is a leader in the medical electronics market of one of the semiconductor industry, companies and medical device companies have established close cooperative relationship, to provide a wide variety of enterprise devices, many series of excellent products.

For example, MCU (microcontroller), SMPS (power control scheme) and RFID (recognition program), these high-performance mixed-signal solutions can meet your portable medical electronic devices of diversified applications.

To micro-controller, for example, to NXP 32-bit ARM microcontroller controlled TFT-LCD interface, ideal for medical monitoring devices display applications, and the micro-controller VFP9 floating-point co-processor could raise complex algorithm of operation efficiency.

These characteristics are ideal for patient monitors, in vitro diagnosis products as well as medical imaging and other high-end medical electronics. And NXP MCU ultra-low power consumption, suitable for portable medical electronics applications, meet the low-end market blood glucose meter, blood pressure, body fat Analyzer, digital thermometer, and heart rate monitor for a low-power needs. Then to power converters, for example, NXP EPS2.0 meet energy star requirements. For example, the following adapters 50W, in the absence of load input power consumption less than or equal to 0.3W; for 250W following, 50W over adapter, no load input power consumption less than or equal to 0.5W. According to the energy-efficiency testing, using green chips NXP TEA1791 than using Schottky Diode solutions can achieve higher efficiency.

In addition, the medical information in a network share, the importance of IC card technology increasingly promoted.

IC card is data storage and management, security, authentication, authorization voucher as well as personal and information system for data exchange and other important platform. But RFID technology can achieve drug tracking, vaccine administration, plasma management, uniforms with single management, medical equipment and laboratory management. And NXP in smart card and RFID applications with undisputed leadership.

As a high-performance mixed signal semiconductor suppliers, NXP's medical electronic programmes with a high degree of integration, fast and precise operation ability, easy to carry, small size, low power, security, stability, and other characteristics, satisfying portable medical electronics field.
