[An intelligent photoelectric oxygen-inhalation calculagraph].
This paper introduces a self-made intelligent oxygen-inhalation accumulative calculagraph. A photoelectric probe is fixed on the buoy of the oxygen flowmeter under non-ventilation conditions. ⋯ When oxygen inhalation pauses, the buoy goes down and the timing stops. When oxygen inhalation starts again, the timing continues and accumulates.

[Better medical devices regulations for better health care: enlightenment for medical devices regulatory reform in China, from experiences of the E.U. and the U.S.A].
The expansion of applications of medical devices has attracted the increased attention of government regulatory bodies around the world to the safety and effectiveness of these products. Most developed countries, such as the United States and European Union, have developed well-established regulatory systems for medical devices, which have also consistently been amended to accommodate the changing requirements of safety and the trend of globalization. The current "Regulations for the Supervision and Administration of Medical Device (China)", established in 2000, has brought about great improvements for the safety and effectiveness of products, safeguarding public health. ⋯ It is suggested that when developing a new scheme of medical devices regulatory reform in China, two prominent aspects have to be considered by policy makers and regulators. Firstly, the global trend of medical devices regulations has to be taken into account. Secondly, the experiences learned from the EU and US systems should be applied to the Chinese regulatory reform in combination with the concrete practice of China.
