ABSTRACT
Corona virus disease 2019 (COVID-19) has been the focus of global attention since its outbreak. With the rapid spreading of COVID-19, serious challenges including medical management system, medical resources, emergency response, medical devices and instruments gradually occur, revealing many shortcomings among these aspects. Herein, through the principles, viewpoints and methods of biomechanics, this article recognizes and analyzes the existing problems that are urgently needed to be solved, such as the study of in-vitro viability of the virus, the biomechanics of aerosol, the fluid mechanics in public transportation and places, the relationship between respiratory diseases and cardiovascular diseases, the improvement of medical devices, with an objective of taking advantages of biomechanics in epidemic prevention and control, so as to promote the development of biomechanics.
ABSTRACT
Objective:To explore the application effect of risk management in quality control of medical apparatus and instruments of operation room.Methods: 172 pieces of medical apparatus and instruments were divided into risk management group (n=86) andcommon management group (n=86). A series of indicators, such as effective acceptance rate, qualified cleaning rate, completed supporting facility, specific aim rate, deficiency rate of quantity, error rate of preparation, wet pack rate of sterilization, lost rate of post surgery and the satisfaction degree of physician, were applied to complete statistic analysis.Results: The effective acceptance rate, qualified cleaning rate, completed supporting facility rate and specific aim rate of risk management group were significantly higher than that of common management group (x2=5.02,x2=7.38,x2=9.35,x2=11.14,P<0.05). The deficiency rate of quantity, error rate of preparation, wet pack rate of sterilization, lost rate post surgery of risk management group were significantly lower than that of common management group (x2=6.63,x2=9.21,x2=11.34,x2=13.28,P<0.05). And the satisfaction degree of physician of risk management group (97.7％, 84/86) was significantly higher than that of common group (73.3％, 63/86) (x2=12.83, P<0.05).Conclusion: The application effect of risk management is better than that of common management in the quality control of medical apparatus and instruments in operation room.
ABSTRACT
Objective:To explore the principles and elements of ethical review of clinical trials regarding medical apparatus and instruments.Methods:This paper introduced Beijing Anzhen Hospital's requirements on considerations for the vulnerable,acquisition of informed consent,the researchers' qualification and experiment design,during ethical review of clinical trials regarding medical apparatus and instruments.Results:Institution review board of Beijing Anzhen Hospital designed principles and standard operating procedures for ethical review of clinical trials regarding medical apparatus and instruments.Conclusion:Ethical review of clinical trials regarding medical apparatus and instruments now is more scientifically standardized,and has become an important approach for the protection of subjects' rights and interests.
ABSTRACT
Objective To investigate the application effect of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center of hospital. Methods The first-time qualification rate of cleaning,packaging and sterility test and incidence rate of nosocomial infection before and after the application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center of hospital.The application effect was comprehensively evaluated. Results The first-time qualification rate of cleaning,packaging and sterility test after the application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center were significantly increased.The incidence rate of nosocomial infection was 1.5％ before and 5.5％ after the application of cleaning packaging of surgical medical apparatus and instruments,the difference was significant. Conclusions Application of cleaning packaging of surgical medical apparatus and instruments in sterilization and supply center can effectively control the cleaning and packaging quality,guarantee the thoroughness of subsequent disinfection and sterilization,decrease the incidence rate of nosocomial infection caused by poor quality of surgical medical apparatus and instruments.It creates reliable medical environment for patients and obtain good social and economic benefit,which is worthy of wide application.
ABSTRACT
OBJECTIVE To attend to the importance and issues of using the enzyme cleaner for the reprocessing of medical instrument. METHODS The principle, usage, precautions, and the selection of enzyme cleaner were analyzed. RESULTS The cleaning of the medical instrument must use the liquid enzyme detergent that has the following characters: clear solution, no or low foam, free rinsing, flexibilities to the water temperature, and no limitation to the water quality. CONCLUSIONS For successful cleaning of the medical instrument the use of the high-quality enzyme cleaner is required. A complete cleaning of the medical instrument is the first step to assure the quality of disinfection, sterilization, and the infection control.
ABSTRACT
OBJECTIVE To establish the basic quality control system for disinfection of medical apparatus and(instruments).in order to meet the national standards of the disinfection quality.METHODS On the basis of background investigation about the disinfection(management) of medical apparatus and instruments from 1997 to 2004 to implemeat the basic quality control system scientifically and continuously and to improve the management of disinfection quality in hospital.RESULTS The disinfection quality of commonly used medical apparatus and(instruments),first-aid devices,combat readiness materials,special instruments and sterilizer,etc was got to(improve) year by year,that created condition to control the emergence of hospital(infection).CONCLUSIONS To(avoid) the exogenous hospital infection due to unsuitable medical apparatus and(instruments).
