Guide: The State Food and Drug Administration promulgated the Guiding Principles for the Technical Review of Mobile Medical Devices Registration, which clarified the definition of mobile medical devices, and clarified the scope of application, technical considerations and registration requirements of mobile medical devices registration. What other noteworthy contents are there in the instrument industry today? Let's look at the details below.

On January 9, the State Food and Drug Administration issued the Guiding Principles for the Technical Review of Mobile Medical Device Registration, which clarified the definition of mobile medical device, and clarified the scope of application, technical considerations and registration requirements of mobile medical device registration. What other noteworthy contents are there in the instrument industry today? Let's look at the details below.

National food and Drug Administration issued guidelines for technology review of mobile medical device registration.

Recently, the State Food and Drug Administration promulgated the Guiding Principles for the Technical Review of Mobile Medical Device Registration, clarifying the definition of mobile medical device, and clarifying the scope of application, technical considerations and registration requirements of mobile medical device registration.

Instruments and instruments today: the first carbon fiber rod ultrasonic testing device developed successfully in China.

The Principles make it clear that mobile medical devices can usually be used to achieve or partially realize the functions and uses of traditional medical devices, so their performance indicators can refer to the relevant requirements of equivalent traditional medical devices. Mobile medical devices and mobile health electronics products are difficult to be clearly defined. All mobile computing devices or software that meet the definition of medical devices belong to mobile medical devices. The applicant should submit relevant registration information to prove the safety and effectiveness of the product according to the type of mobile medical device, the characteristics of the mobile computing terminal used and the clinical requirements.

Minimally invasive glucose monitoring Sano got $Fitbit600 million risk financing

Fitbit recently invested $6 million in a glucose monitoring startup called Sano, which seems to be part of a larger Fitbit plan. Fitbit plans to make fitness equipment more valuable for overall health.

The so-called minimally invasive glucose monitoring, which means no blood or only monitoring subcutaneous interstitial fluid, is also a trend for some of the world's largest technology companies. Alphabet's Verily says it is developing a small continuous glucose monitor. It is said that apple is also studying some kind of needle free blood glucose tracker. However, it is very difficult to accurately test blood sugar without damaging the skin.

Last September, Fitbit said it was working with Dexcom to bring continuous blood sugar monitoring to the Fitbit Ionic smart watch. Fitbit also says it is working on a solution to track sleep apnea, but it may require more advanced technology than Fitbit's existing products.

Canadian researchers develop new nondestructive testing technologies to breed drought resistant varieties faster.

Researchers at the University of Saskatchewan in Canada have developed a simple nondestructive test that can screen hundreds of wheat leaf samples in a day, reducing the time and cost of traditional breeding methods for drought-resistant varieties, according to a report. The results were published in the November 2017 issue of Physiology Plantarum.

Using flag leaf wax, the researchers compared drought-tolerant Tetler wheat varieties with those more susceptible to drought conditions to examine plant morphological and chemical characteristics. Flag leaf is the last leaf appearing in the process of plant growth, which is very important for high yield.

The current breeding method is based on the drought tolerance of crop yields, and field experiments are used to determine the results. This new approach will enable scientists to know more about the characteristics of drought-tolerant varieties earlier, thereby reducing costs, and faster delivery of new varieties from the laboratory to the field. The project will expand to new varieties and eventually focus on other crops, such as rape, to enable Canadian farmers to remain competitive in the global market.

The first ultrasonic testing device for carbon fiber sucker rod has been successfully developed and put into operation in China.

Shengli Oilfield Technology Testing Center has completed the on-site debugging of the "Carbon Fiber Sucker Rod Ultrasonic Online Continuous Testing Device" in the Third Industrial Park of Shengli Xinda Industrial Group Co., Ltd. The on-site data acquisition has achieved the desired results, which marks the first domestic carbon fiber sucker rod ultrasonic testing device developed by the Center. You have to succeed.

As a new type of pumping equipment, carbon fiber sucker rod has remarkable advantages in energy saving, deep extraction and reducing workover frequency. It is a new direction of development and application of oil recovery technology. However, how to check the quality of production and the reliability of the operation process through the detection is a major problem facing the popularization and application of the technology.

In order to solve the practical problems in the popularization and application of carbon fiber sucker rods, the technicians have studied and tested a number of non-destructive testing technologies, and finally determined the feasibility of using ultrasonic to carry out on-line continuous testing. Combining with the working conditions of carbon fiber sucker rod production line and the characteristics of ultrasonic technology, technicians carried out the research and development of detection device. After continuous experimental testing and program changes, the on-line detection device of carbon fiber sucker rod based on ultrasonic immersion was finally developed.

Huang Yanyi team has made important progress in DNA sequencing technology and technology.

With the support of the National Natural Science Foundation of China, the Huang Yanyi Research Group of Peking University has made important progress in DNA sequencing methods and techniques. A novel sequencing method, Error Correction Coding Sequencing (ECC), is developed. This method adopts a unique strategy of edge synthesis while sequencing (SBS) and utilizes multiple sequencing processes. The redundancy of information generated by degenerate sequences greatly increases the accuracy of sequencing.

Chinese tourists speak loudly? The noise detector gives you the answer.

How big is the voice of Chinese tourists? To clarify this problem, the daily magazine SPA used noise detectors to test the noise level of people in different countries. To be fair, the subjects were Chinese tourists, Chinese, Japanese and other foreigners in their own countries, and the venues were Shinjuku Kabuki, Tokyo, which brought together tourists from all over the world.

The test results showed that Chinese tourists spoke at 76 decibels at home appliances stores, similar to the city noise benchmark set by the Japanese Ministry of Environment (the city noise standard set by the Japanese Ministry of Environment is below 70 decibels during the day). In Japanese-only restaurants, the Japanese speak at 60 to 70 decibels, while in Chinese-dominated restaurants, they can speak at 70 to 80 decibels without making a noise.
