The article briefly introduced the basic situation of "top 10 health technology hazards", which issued by ECRI of United States. We comprehensively analyzes the main contents and characteristics of "top 10 health technology hazards", when issued from 2013 to 2017. Discussing the influence factors of medical devices application quality, which "top 10 health technology hazards" focus on, from human factors, risk of medical devices, information technology and other auxiliary measures. Then we introduced relevant practical measures, and discussed related enlightenment and thinking that combined with working practice.

Objective To investigate the ligamentization process of autogenous hamstring grafts after anterior cruciate ligament (ACL)reconstruction and explore its potential influencing factors.Methods Patients undergoing the ACL reconstruction between January and December 2014 were recorded demographic data including their gender,age,weight,height,body mass index (BMI),general joint relaxation(the Beighton score),and their surgical duration.Six,12,and 24 months after the operation,the signal intensity of the proximal,middle and distal part of the ACL grafts was measured using MRI,and the signal to noise quotient (SNQ)was calculated to assess the graft maturity.The data were analyzed statistically to explore the ligamentization process of grafts and its potential influencing factors.Results A total of 87 patients receiving ACL reconstruction were enrolled in this study.The results showed that the SNQ of the proximal and middle part of the ACL grafts decreased gradually with time,and significant differences were observed in the SNQ value of the proximal part between 24 months and that of 6 and 12 months(P＜0.05).There was no significant difference in the SNQ value of the distal part at different time points.The SNQ values of grafts were not significantly affected by the gender,age,body weight,height,BMI,Beighton score or ACL duration(P＞0.05).Conclusion The ligamentization of autogenous hamstring grafts after ACL reconstruction increases gradually with timent positive correlation with postoperative time.
RESUMO
CT laser simulation positioning system is a necessary auxiliary device for radiotherapy. Its main purpose is to position patients by simulating different kinds of treatment machine. In order to demarcate the mark of the iso-center, it is common to use the laser positioning device to indicate the iso-center. The kernel technology of the laser positioning system is the controlling of the step progress motor by using the MCS, which is to control the movement of step progress motor using the wheel of the motor. This design uses MCS-51 to control step progress motor by the way of exporting the rectangle wave form through I/O port of 8255 chip. The system configuration is simple, the operation is convenient and the positioning is precise.
RESUMO
Through summarizing medical consumable emergency safeguard mechanism in "5.12 earthquake relief",and combining with the related laws and regulations of the emergency safeguard,the characteristic of the medical consumable emergency safeguard mechanism are analyzed,and then the correlated proposal about which the medical consumable e-mergency mechanism in construction of military hospital emergencies are putted forward.
RESUMO
The improvement of quality control and management of Chinese medical equipment are discussed by analyzing the experience of other countries, aiming at the enhancement of medical equipment security, and social and economic benefit of the hospital.
RESUMO
With the increasingly wide application of advanced science and technology, medical equipment, which reflects the overall strength of the hospital and medical activities, becomes more and more important. Medical equipment raises the level of medical care and increases the hospital income; while meantime, it is also bound to be accompanied by a range of purchase and management problems. The problems of medical equipment purchase and management in hospital are analyzed, and improvement opinions about equipment purchase, approval, use, maintenance and rejection are proposed in order to improve the actuality of equipment purchase and management.
