一医学监护系统发展趋势
我国的医疗器械工业总产值20世纪90年代以来一直保持快速增长,平均增幅一直保持在12%~15%的水平。根据医疗器械行业“十五”规划的预测,2010年我国医疗器械行业总产值将达到1000亿元。随着我国宏观经济;睁进入另一个稳定增长周期,今后几年中国市场对医疗器械的需求将一直保持强劲势头。根据国家统计局的数据,近3年我国医疗监护设备销售收入年均增长速度在10%以上,而利润总额也实现了与销售收入的同步增长。 相似文献

医疗器械行业是一个多学科交叉、知识密集、资金密集型的高技术产业,进入门槛较高。目前中国医疗机构的整体医疗装备水平还很低,全国17.5万家医疗卫生机构拥有的医疗仪器和设备中,有15%左右是20世纪70年代前后的产品,有60%是上世纪80年代中期以前的产品,它们更新换代的过程又是一个需求释放的过程,将会保证未来10年甚至更长一段时间中国医疗器械市场的快速增长。 相似文献

The aim of this study was to make a comparative evaluation of the surface topography of the cervical third and tip of four different rotary systems, before and after being used 12 times, in resin blocks with simulated root canals with standardized 45° curvatures, and analyzed by scanning electronic microscopy (SEM). A total of 1,440 resin blocks with simulated root canals and standardized curvatures were used. The blocks were divided into four groups and prepared by the crown down technique according to the manufacturers' recommendations: Group 1 (G1)—K3®, Group 2 (G2)—Protaper Universal®, Group 3 (G3)—Twisted Files®, and Group 4 (G4)—Biorace®. After each preparation, the instruments were washed and autoclaved. A total of 24 instruments were selected, being three new instruments and three after having been used for the 12th time, from each group. These instruments were analyzed by SEM. To perform the evaluation, 24 micrographs were observed by 12 evaluators who attributed a score to the images according to a template. In the qualitative analysis of the cervical region and tip of new instruments, it was observe that the files of Groups G4 and G2 were the least rough and those of G1, the roughest. In the same manner, the cervical region of the instruments was qualitatively analyzed after the 12th time of using them, and there was no statistically significant difference at a level of 1% (ANOVA P < 0.01) between G2 and G4 as well as between G1 and G3. As regards the tip, it was observed that there was no statistically significant difference, at a level of 1%, between the groups: G1 and G3, G1 and G4, and between G3 and G4, and there was statistically significant difference at a level of 1%, between group G2 and the other groups, with G3 having the greatest roughness (ANOVA P < 0.01).

A common problem found in the calibration laboratories is the reliability of the results obtained from calibration of instruments, especially when they do not have a built-in communication interface. In this case, the time consuming is increased significantly and the calibration may be subject to human error. Thus, many approaches based on computer vision have been proposed in the literature for automating calibration processes. However, most of them first simplify the images, usually using operations such as segmentation/binarization, for after proceeds the recognition of the digits. The issue lies in the fact that these simplifying operations throw away the rich grayscale information, decreasing the robustness of the algorithms, mainly when the images are affected by illumination changes, noise or JPEG compression. In this paper it was proposed two segmentation-free algorithms for automating the calibration process of digital and analog measuring instruments without built-in communication interface. The first one is based on template matching with normalized cross correlation for reading the display digits and the second uses radial projections and Bresenham algorithm to determine the pointer position in analog instruments. The experimental results showed that the proposed algorithms presented high accuracy and performance and can be used in real time systems applied to calibration processes. 相似文献
