A device and method for accelerated sedimentation of urine formed components based on mechanical waves

Abstract

The invention relates to a device and method for accelerating precipitation of urine formed components based on mechanical waves. The device includes a box body and a U-shaped sedimentation tank installed in the box body, a vibration mechanism and a transmission mechanism. The U-shaped sedimentation tank includes an outer shell and an inner shell embedded in the outer shell. The bottom of the inner shell is provided with a drainage conduit 1 communicating with the inside of the inner shell. A positive pressure valve is installed on the drainage catheter one. The vibration mechanism includes a mechanical wave generator, a retractable sleeve, a transducer and a vibration plate. The output end of the mechanical wave generator is connected with the input end of the transducer, and the output end of the transducer is connected with the vibrating plate. One end of the telescopic sleeve is connected with the control motor, and the other end is connected with the transducer. There are station one, station two and station three in sequence in the box. The device and method make the sedimentation speed of the formed components of urine controllable, improve the quality of the sedimentation layer, are easy to realize automation, and have a wide application range.

Description

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

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
