Preanalytical errors contribute to a large proportion of total laboratory errors. In order to achieve continuous laboratory
improvement, it is important to focus on all phases of patient specimen testing i.e. preanalytical, analytical and post-analytical.
With large variations in the way venous blood specimens are collected using diverse devices in the country, the effect of
such practices on specimen quality is not known. The purpose of this study was to monitor fourteen specimen preanalytical
quality indicators in order to compare the usage of evacuated blood collection devices with needle and syringe open collection
using either disposable tubes or re-washed glass vials. The study involved 26638 patient specimens assessed over a period
of 6 months. The results demonstrated that evacuated closed blood collection resulted in an approximate 100-fold reduction
in the incidence of hemolysis in samples. Similarly, there was a 200-fold reduction in incidence of insufficient specimen
quantity while using evacuated collection system. It was also found that incidence of specimen contamination, improper volume
of sample collected, and specimen spillage was also lower when the evacuated collection system was used. Further, it was also
observed that the facility with a laboratory information system demonstrated much lower specimen identification and related
errors. The observed results clearly demonstrate that the usage of the evacuated blood collection system resulted in improvement
of preanalytical specimen quality as compared to needle and syringe usage. 相似文献

In this paper a novel type of frictionless mechanical inerter device is presented, where instead of gears, motion of the flywheel is achieved using living-hinges. The design is a type of pivoted flywheel inerter inspired in part by the Dynamic Anti-resonant Vibration Isolator (DAVI) concept, which was first developed in the 1960s. Unlike the DAVI, it will be shown that the pivoted flywheel inerter has the advantage of producing balanced forces. Furthermore the use of living-hinges eliminates the need for gears or other frictional elements in the inerter mechanism. To demonstrate the utility of the new concept, a bench-top experiment was performed using a small-scale living-hinge inerter manufactured using polypropylene hinges. By estimating the experimental system parameters, the transmissibility results from the experiment could be compared to a mathematical model. These results showed that the living-hinge inerter provided an isolation effect of at least three orders of magnitude in terms of the maximum amplitude reduction from the uncontrolled system compared to that with the inerter added. Although friction was eliminated, the living-hinges did introduce additional damping, and this was found to correspond to an increase in the equivalent damping ratio for the uncontrolled system of 1.2%. It is shown that the living-hinge inerter developed in this paper fits all of the essential conditions required to be a practical inerter device. Furthermore, as it operates without mechanical friction, or fluid flow, it represents a new paradigm in experimental inerter technology. 相似文献

尝试依据生计资源的拥有量将农村的可持续发展态势划分为三个等级,即"趋贫状态"、"维持状态"、"趋富状态"。借助1992年至2011年的数据为基础,研判我国农村发展处于中等可持续的阶段,生计资源属于"维持状态"。农村可持续发展态势测度与评价,是对农村发展的可持续性度量体系的丰富与完善,也是探索生计可持续发展能力的有益尝试。 相似文献
