NXP's technical smart hand hygiene system can effectively prevent medical infections

Shanghai, China, September 19, 2011 – Although the US Centers for Disease Control and Prevention (CDC) stated that hand washing is the most important procedure for preventing medical infections, the lack of cleanliness of medical staff has always been an important cause of infection. The consequences include not only extending hospital stays, delaying patient inactivity, increasing bacterial resistance to antibiotics, but also increasing hospital and patient costs and even death. HyGreen® Hand Hygiene Tracking System, designed by HyGreen, is an innovative solution that actively reminds busy health care workers to wash their hands and track all of the hospital's hand washing records and contact with healthcare professionals during patient visits. The HyGreen system uses NXP Semiconductors NV (NASDAQ: NXPI)'s low-power wireless chip technology to capture and transmit data on the hand washing of healthcare professionals, significantly improving the health of the hospital.

HyGreen is using the NXP JN5139 wireless microcontroller and JenNet wireless network stack optimized for low power, low data rate and cost sensitive applications, and plans to use the NXP JN5148 microcontroller later this year. Based on the IEEE 802.15.4 specification, JenNet provides a robust self-healing network that helps the HyGreen system track every hand-washing process and access to the hospital bed for each health care provider, ensuring that the hospital effectively monitors its personnel's compliance with the hand hygiene protocol.

Currently, the Hyal Hand Hygiene Tracking System is used in the first-class hospitals in the United States, such as St. Jude Children's Hospital, the University of Illinois at Chicago Medical Center, and the Jesse Brown Veterans Affairs Medical Center. The system works by first washing the hands with soap or hand sanitizer, then placing the hand under the HyGreen sensor for testing, and the sensor sends a “clean” message over the wireless network to the health care provider's HyGreen badge. The badge then flashes green. When the health care provider is close to the hospital bed, the HyGreen monitor on the bed checks whether the badge passes a "clean" signal. If the badge is not green, it will vibrate and alert the health care provider to wash their hands. Relevant hand washing reports will be provided to hospital administrators in real time.

Ron Youngblood, deputy director of HyGreen's operations, said, "The major hospitals rely on us to provide a hand hygiene system to improve the health of health care workers, thereby ultimately improving efficiency by reducing medical infections. With the assistance of NXP, We designed and developed a highly reliable solution that is both cost-effective and convenient for routine maintenance in the hospital. After several months of use, the battery life of this HyGreen Hand Hybrid Tracking System remains strong, thanks to the super The low-power NXP wireless module consumes only one-tenth the power of WiFi."

According to a recent study by the American Society of Healthcare Epidemiology (SHEA), the medical infection rate at Miami Children's Hospital was reduced by 89% after using HyGreen's hand hygiene reminder system for seven months. The report also shows that the HyGreen component and tracking system is 100% accurate and provides the same intensity of monitoring for all shifts in the hospital's extremely busy child oncology department. In addition, HyGreen has won numerous awards, including the "2010 Outstanding Medical Device Design Award" and the "Best Scientific and Technological Achievement Award 2009" selected by the famous popular science magazine "Popular Science".

“The HyGreen Hand Hygiene Reminder System is a revolutionary solution that demonstrates that 'smart' wireless technology can help us meet the enormous challenges facing the healthcare industry – improving patient care, saving lives and saving money.” Jim Lindop, chief strategist for the semiconductor low-power RF product line, said, "HyGreen continues to change the hygienic habits of hospitals, clinics, schools, restaurants and other places, and we look forward to continuing to work with such companies."
