Because of the control attributes of medical consumables, this may resulted in inaccurate and cross-cycle of cost accounting. In order to achieve the refined cost-accounting management, the relevant company system and process modification are studied.The high quality control problems of 49 institutional degree medical unit clinical tests in medical center from 2016 to 2021 were summarized, therefore the factors behind the difficulties had been examined through the point of view of all events active in the clinical test. The improvement steps had been talked about, which including enhancing the administration system, strengthening the training of scientists and optimizing the choice strategy, strengthening the obligation and legislation awareness of applicants, and formulating the selection foundation of individuals an such like. All the overhead is designed to ensure the quality of clinical trials click here and provide guide for clinical trial managers and implementers.This study quickly presents the basic principle of sterilization, the attributes of ethylene oxide sterilization for health devices therefore the key factors about sterilization effectiveness, analyzes and measures up three methods found in this product launch of medical devices sterilized by ethylene oxide test for sterility, standard release and parametric launch, and targets the theoretical basis, feasibility, validation requirements, pros and cons of parametric release.As a kind of class II medical device, medical optical radiation protective eyewears should meet the requirements of security and effectiveness. In this study, the assessment system of health optical radiation safety eyewears is initiated. Combined with the medical product registration device division tips, the category Wang’s internal medicine method of medical medical faculty optical radiation safety eyewears is offered. Health optical radiation protective eyewears aren’t just put together spectacles, but additionally have actually special optical radiation security overall performance. The performance evaluation method of health optical radiation defensive eyewears in addition to evaluation approach to rack life for medical optical radiation defensive eyewears are given.The study explored the strategy of determining the diameter of clear optic of intraocular lenses by analyzing the look axioms and influencing facets of clear optic. Measure and compare the clear optic diameters of intraocular contacts from -10.0 D to 36.0 D respectively. The measurement results of the two practices have actually good consistency and can be used when you look at the dimension of clear optic. But considering the precision and convenience of actual dimension, profile projector dimension concept is more appropriate conventional mass production testing. The Schlieren strategy strategy can provide more useful information in product development and show information phase, and can be utilized as an auxiliary confirmation way of obvious optic diameter measurement. To define the silver in chitosan anti-bacterial solution, also to establish an approach for the determination of silver content in examples. SEM, EDS and SP-ICP-MS can be used when it comes to characterization of gold particles in chitosan anti-bacterial serum. Microwave digestion-flame atomic consumption spectrophotometry technique is straightforward, practicable, high accuracy and high quantitative accuracy, which will be ideal for the quantitative analysis of silver in chitosan anti-bacterial serum.SEM, EDS and SP-ICP-MS can be utilized for the characterization of gold particles in chitosan antibacterial serum. Microwave digestion-flame atomic absorption spectrophotometry technique is not difficult, practicable, high precision and high quantitative precision, which will be ideal for the quantitative evaluation of gold in chitosan antibacterial gel.Electromagnetic compatibility evaluation of proton therapy system is different from compared to old-fashioned items in an anechoic chamber. It’s high demands on the unit of test structure, the comprehension of relevant standards, the formulation of procedure mode, the choice of test area, therefore the test of ambient sound. In accordance with the requirements of GB 4824-2019 standard, the test approach to radiation emission of proton therapy equipment originated to provide research guidance when it comes to business, and the dilemmas experienced within the real test were studied.In view for the shortage of analysis regarding the seismic performance of health imaging gear, this paper investigates and summarizes the seismic regulatory needs and seismic examinations of health imaging gear, and targets the parameter selection, detection steps, end up assessment and recognition equipment needs of seismic detection of health imaging equipment. The seismic test data of health imaging gear with various installation modes are reviewed, as well as the seismic performance of health imaging gear is reviewed and summarized.A medical device recall event tracking system was created, which could allow the people to get the recall, early-warning and other information regarding health devices with time.
