Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for accelerated precipitation of urine formed components based on mechanical waves. Background technique [0002] With the acceleration of the pace of social life and the improvement of living standards, people gradually strengthen the importance of personal health. The diagnosis of various diseases including chronic kidney disease, cardiovascular disease, tumor, and diabetes requires rapid detection of abnormal state of urine formed components. [0003] Urine testing needs to obtain the formed components in the urine first. Traditional extraction methods mainly include centrifugation and natural sedimentation, but these two extraction methods have their own advantages and disadvantages. The centrifugation method needs to use a centrifuge to centrifuge the urine for 3-5 minutes. Although it can achieve the purpose of concentrating the urine sediment,...

AI Technical Summary

Problems solved by technology

The centrifugation method needs to use a centrifuge to centrifuge the urine for 3-5 minutes. Although it can achieve the purpose of concentrating the urine sediment, it is difficult to grasp the amount of urine residue extracted, and it is easy to miss abnormal components. At the same time, due to the mechanical tension of the centrifuge, the fragile Casts and cell destruction

However, using the natural sedimentation method, it usually takes a long time (more than 5 minutes) for the formed components of urine to naturally settle to the same plane at the bottom of the sedimentation tank. This requirement is often difficult to achieve in practical applications, resulting in insufficient settlement. The sediment layer is too thick, and due to the difference in relative density, different urine formed components have different sedimentation speeds, and they will cover each other at the bottom of the sedimentation tank. The sediment layer is too thick, resulting in low imaging quality when observed by the microscope, which seriously affects the urine. The accuracy of liquid test results

On the other hand, since the urine of different patients often has different viscosities, the natural sedimentation time of urine sediment varies greatly among different individuals, which is not conducive to the realization of automatic
