In recent years, Zhejiang Institute of Metrology once undertook the development of a major scientific research project “Study on the Standard of Biopharmaceutical Micro Flowmeter Measurement Standardsâ€. The main research object is a set of biomedical micro-liquid flow metering standard device combining a static mass method and a dynamic piston method. With the "double cup double weighing" framework, a small fully symmetrical commutator and a constant temperature water supply system are designed, and the measurement accuracy is improved by using a low volatile liquid layer covering technology.
The purpose of this project is to ensure accurate and reliable metrological performance in the field of biomedicine, and to achieve even speed of micromedicine in clinical treatment, accurate drug dose play an active role, to improve the quality and effectiveness of biomedical care, and to ensure the health of patients. Technical Support. After many years of exploration by Zhejiang Institute of Metrology, it finally achieved a float flowmeter, a mass flowmeter, a micropump detector, an infusion pump/injection pump, and a detection device with flow rates in the range of 0.1 mL/h to 1000 mL/h. Calibration verification is performed to improve the verification efficiency under the premise of ensuring high precision and high stability.
The study of the “Biopharmaceutical Flow Metering Standard Device†is based on the “Research on the Measurement Standard of Biomedical Micro Flowmeters†and improves the performance of advanced technologies in the field of biomedical micro flow metering. Zhejiang Metrology Institute attaches great importance to the transformation and application of scientific and technological achievements. Starting from the actual needs, it constantly accelerates the transformation of scientific and technological achievements, bringing new innovations to the industry. It is understood that in the recent results of the 2016 provincial science and technology award industry review announced by the Science and Technology Department of Zhejiang Province, the “standard device†research project won the third prize of scientific and technological progress in Zhejiang Province.
[China Instrument Network Instrument R&D] With the rise of semiconductor manufacturing, bio-engineering, and medical and chemical industries, flow measurement is extending to the low-end, and measurement needs for small-flow micro-flows are becoming increasingly prominent. The research on microfluidics and the demand for accuracy of minute flowmeters have also attracted the attention of more and more scientific workers, and the micro flow metering standards have become one of the most urgently needed standards in the current fluid metering field.
