Objective The diagnosis and treatment of modern hospital are greatly influenced by medical devices. With the widespread introduction of medical equipment, the scientific management how to carry on the instrument and appliance by the administrative department of hospital becomes an unavoidable problem. Methods Based on the definition of medical equipment, basic attributes and management skills, some key questions which the administrator should notice and solve in the scientific management are introduced, and gives out the principle and method. Results It is pointed out that scientific management can correctly guide the investment of equipment, and gain great benefit with a minimum input. Conclusion Investment according to the developmental strategy is proposed, which provides strong theoretical basis for leadership and administrative departments.

This paper mainly describes the software design for a new type of ultrasound power detecting system based on instrument, in which data acquisition module, digital filtering module, data conversion module, zero setting and adjustment module. In the required accuracy, this system is more convenient and practical than the former power detecting system.

Objective: To supply the quality of hospital centers, conduct research and analysis, develop appropriate purification scheme. Methods: According to the specific hospital ward equipment used and production center with the use of state gas sampling filter device;through the device each ward of the hospital wards with a central gas sampling equipment, comparison and analysis. Results:through the filter sampling, analysis of equipment with a gas composition of trace impurities, impurities resulting inferred parts, the first time to get in touch with the manufacturers to jointly negotiate improvement programs. Conclusion:Hospital Center survey analysis is a gas quality monitoring and promotion of the development, the need to promote open each hospital to develop a central supply more complete safety indicators. Such a center gas quality testing program can be more effective in protecting the quality of gas supply, more conducive to clinical treatment and use.

Objective To analyze the power interference during ECG machine testing and to propose countermeasures.Methods Some measures in power supply stability, shielding, grounding and wire winding were carried out to reduce the influences of 50 Hz interference on ECG machine testing.Results The influences of the power interference were reduced greatly on ECG machine.Concluslon The performances of ECG machine can be ensured by restraining the power interference.

Upper gastrointestinal hemorrhage (UGH) is a kind of intensive disease commonly encountered clinically. In recent years, the diagnosis and treatment method of UGH had achieved satisfied progress. But with the development of aged tendency of population, its morbidity is still in a high level. Especially in older patients with serious complications, the fatality rate is much higher. It has been proved practically, traditional Chinese medicine (TCM) has remarkable effects in treating UGH. This article summarized the progress of TCM or integrative medicine studies on UGH through etiology and pathogenesis, therapeutic principle and methods.

Objective To investigate the effect of Buyanghuanwu decoction(BYHWD) on the expression of growth-associated protein 43(GAP-43) and synaptophysin(SYP) after focal cerebral ischemia in mice.Methods Focal cerebral ischemia was induced by 30 min of middle cerebral artery occlusion followed by reperfusion.BYHWD (20 g/kg) was administered orally 24 h after ischemia and once a day.The neurological score and the corner test were used to evaluate sensorimotor function on 1,3,7,and 14 days after ischemia.The expression of GAP-43 and SYP in the ischemic boundary zone was determined by immunohistochemistry 14 days after ischemia.Results Compared with the model group,BYHWD significantly ameliorated neurological dysfunction at 3,7 and 14 days and reduced the number of right turn at 7 and 14 days after ischemia(P ＜ 0.05).The average optical density of GAP-43 and SYP was 0.217 ±0.012 and 0.278 ±0.019 at the boundary zone in model group 14 days after ischemia,respectively.BYHWD also significantly increased the immunoreactivity of GAP-43 (0.250 ± 0.013)and SYP(0.323 ± 0.017) (P＜ 0.01).Conclusion BYHWD promotes axonal regeneration and synaptic plasticity in the ischemic boundary zone,which may contribute to functional recovery after focal cerebral ischemia.

Objective To develop an improved product of the existing battlefield diagnosis and treatment bed by making the product smaller,the structure firmer,the function more perfect and the use more convenient,thus to benefit the use under the battlefield situations,and to improve the logistics support ability.Methods '08F,304'steel materials were adopted as prop-up parts of the bed.The fold type structure design,infusion shelf and mosquito net pole functions could be exchanged with each other.The special oxygen bottle clip was equipped.Results It had such advantages as lighter weight(half of the former),enlarged strength,diverse functions,simple operation and easy taking.As far as safety and reliability and operation flexibility concerned,it was far improved compared with the former one.The treatment bed met the requirement of diagnosis,treatment and nursing for patients under battlefield conditions.National patent of the product was declared.Conclusion The portable battlefield diagnosis and treatment bed is used under the field situation,so some more complicated structures and functions of the normal beds are omitted.Meanwhile,reasonable function combination and material and structure design are key factors in development.[Chinese Medical Equipment Journal,2008,29(2):10-11,14]

Objective To develop a suit of rapidly-fixed evacuation stretcher for safe and convenient transportation of the wounded. Methods By making use of the expansion-shaping property of a bubble-shaped material produced by the chemical reaction of two kinds of Macromolecule materials, and the restrictive effect of body shape matching cotton fabric fixation-bag, a new type of stretcher was developed. Results It was proved by the maneuver and all kinds of traffic accidents that the field stretcher could provide dependable safeguard for the wounded, and the effect was very well. It was suitable to carry out the second or the third treatment and other transportation schemes. Conclusion This new type of field stretcher is light, portable and easily-operated, and besides, it can be used repeatedly.
