Embodiment Construction

[0046] 1. Automatic sampling operation: the 2ul urine sample to be tested is sucked into the counting chamber through the liquid flow control system and mixed evenly. The liquid flow control system is connected to the counting chamber through pipelines. The counting chamber is a hollow transparent glass component. The volume is 2ul;

[0047] 2. The urine inhaled into the counting chamber is captured by the microscopic camera system;

[0048] 3. Computer image automatic recognition software automatically classifies, recognizes and counts the captured sediment images:

[0049] a. Image entry: use a microscope system with a digital camera, and adjust the microscope objective lens to 400 times, scan the sediment image in the uncentrifuged urine and enter it into the computer;

[0050] b. Image preprocessing: For the input image, perform basic processing to improve the effect. It mainly includes: image denoising, image contrast transformation, automatic adjustment of illumination...

Abstract

A method for detecting urinary tangible composition includes starting up sample automatic feeding system; carrying out image-shooting for urine absorbed in counting chamber by microscopic shooting system; carrying out automatic classification, identification and count for obtained image of urinary dregs by image automatic identifying software on computer and outputting results.

Description

technical field [0001] The present invention relates to the improvement of urine sediment detection methodology. technical background [0002] At present, the centrifugation method has been used in the detection of urine sediment. The traditional method is the glass slide method. After the urine is centrifuged, it is directly smeared on the glass slide, and then placed under a microscope for manual microscopic examination. The thickness of the smear cannot be controlled by this method. The volume is fixed, so it is not easy to standardize, and the test results are not easy to quantify. In recent years, in order to standardize the detection of urine sediment, the counting plate method is often used. The urine is centrifuged and dropped into the counting plate, and counted manually under a microscope. There are grids of fixed size in the counting plate, which can achieve standardization, but this method The operation is cumbersome and time-consuming, and the results are not e...
