As a kind of initiative maintenance,preventive maintenance mainly aims at prolonging service life of medical equipment,extending their fault-free time and lowering the whole life expense.It is an important measure that preventive maintenance be strengthened in keeping the safe and highly efficient operation of medial equipment for maximum social and economic benefit.The work flow design of medical equipment preventive maintenance is introduced including the plan,execution and check,giving guidance to medical equipment preventive maintenance.[Chinese Medical Equipment Journal,2008,29(2):71,73]

This paper discusses how to strengthen the quality management of low-cost medical consumables in such aspects as purchase,check and acceptance,deposit and provision of low-cost consumables.

Operation rules of sterilizing are put forward.Responsible persons with working licenses are selected.The cleanout,packing,loading of pre-sterilized goods are standardized.Sterilizing effects(physical monitoring,chemical monitoring,biological monitoring,B-D test) are inspected.Requirements in maintenance and metrology test are raised.The content and methods for quality control of sterilized goods by using decontamination device are introduced systematically.It is instructive to enhance decontamination quality and lower infection rate in hospitals.

On the basis of the system requirement on medical oxygen supply in modern hospital, from the aspects of rigorous installation, ensuring logical course environment, following related technological standard and enhancing personnel training, the whole quality course management is put up. It is indicate that proper equipment and quality control in evary link are the quarantee of clinical service.

This paper introduces the structure,technological process and design of the elrctrocardiomonitor system with whole course.It accomplishes the real-time collection,analysis,storage,inquiry and quotation of whole course ECG information.

The general situation of sudden public events is introduced.Considering the characteristics and phases of massive earthquake disaster,the system of emergency medical supplies for sudden public events is set up in terms of storing and managing the emergency medical supplies by reasonable determining the amount of all kinds of emergency medical supplies such as goods reserve,market reserve,production & technology capacity reserve,etc.

Objective To investigate the influence of hypoxia on leptin expression in serum,CSF and brain tissue of C57BL/6J mice.Methods C57BL/6J mice were divided into 3 groups:the normal control,24-hour hypoxia group and 48-hour hypoxia group.The latter two groups exposed to hypoxia in the man-made auto pressure and hypoxia control cabin(XQ-I).Radioimmunoassay was used to detect the leptin level.Results The leptin level in the serum,CSF and brain tissue of mice exposed to hypoxia were higher than that of normal control,but no difference was found between 24-hour hypoxia group and 48-hour hypoxia group.Conclusion Hypoxia probably induces the increasing of leptin expression in fat tissue,as well as in the central nervous system.
