One case of rare giant mucous cyst of nasal sinus that implicated frontal, ethmoid and maxillary sinus was in our hospital. The patient manifested mainly slowly developing swelling and pain of cheek, exophthalmos and visual impairment. The image studies indicated cyst of nasal sinus, including frontal, ethmoid, and maxillary sinuses. The clinical diagnosis was cyst of frontoethmomaxillary sinus.

Objective:To investigate the feasibility of hemodialysis machine preventive maintenance model of based on quality control detection.Methods: Selected sample of 32 hemodialysis machines of two major imported brands, 16 of them using the traditional preventive maintenance mode for maintenance, and the other 16 sets of quality control detection based preventive maintenance hemodialysis machine maintenance mode. That: by use of HDM99XP detector instrument for testing the five hemodialysis machine main indicators, maintenance cycle is 16 weeks, and then the equipment failure rate indicators of two modes of preventive maintenance were compared.Results: The hemodialysis machine preventive maintenance model of based on quality control detection rise superior to the traditional maintenance mode in lower failure rate, quantitative, objective, and less affected by human factors.Conclusion: The hemodialysis machine preventive maintenance model of based on quality control detection was better than the traditional preventive maintenance mode,also a promising preventive maintenance mode.

This paper puts forward existing problems and conflicts in the work of third class medical metrology stations in army,raises suggestions from 5 aspects including enhancing metrology awareness,fulfilling rules,setting strict standards,etc.

The military hospital's department of medical engineering is limited by authorized size and system.The existing problems in the construction of department of medical equipment are analyzed and some suggestions are given.The construction of department of medical equipment should be made up of three parts: equipment repairing department,medical metrology department and archives department.The construction is also discussed in such aspects as the rules,methods,goals,human resource management,engineer's training program,and reparing mode.

By introducing the basic concept and principle, the advantages and characteristics of ASV technology are highlighted. Based on clinical application, suggestions on how to correctly set ASV parameters are given.

Present situations of the third class medical station in army hospital are discussed in 3 aspects including the recognition of leaders,actualities of metrology work and situation of metrology personnel.Suggestions on the third class medical station are given as follows: cultivation of personnel to promote the construction of medical metrology station;information sharing to enhance metrology level;broad propaganda on metrology regulations to strengthen supervision;continuous subject construction of medical metrology.

Management on medical equipment is discussed and the utility and benefits are analyzed.Several aspects of management of medical equipment in our hospital are mainly introduced such as purchase,check & acceptance,use,maintenance,metrology and scrapping.

Quality control of medical equipment is very important to the diagnostic accuracy and the cure effect. The work of the quality control is the main technical basis of the hospital construction in promoting medical development, and it's also an important content of the modem medical management. The status, causes and countermeasures of medical equipment quality control in military hospital at the present time are analyzed and discussed.

Objective To establish quality control system for medical equipment to ensure its application safety and quality. Methods All aspects of medical equipment management were analyzed. Results All aspects of medical equipment management had to be paid attention to. Conclusion Keeping Improved quality of medical equipment contributes to the decrease of the doctor-patient dispute.
