Changsha Evening News, Changsha Mobile, December 8 (High-tech Lugu reporter Yin Ting) How many danger signals are hidden in a 10ml urine test tube? How many sets of data are needed to prove a urine routine examination report? Under a microscope, more than 300 high-power fields per microliter of urine are needed to scan and analyze the final results. In the past, in the era of manual microscopy, experienced doctors could complete a maximum of 10 sample tests per hour; now, with automated "wings", a single microscopic inspection machine developed by Aiwei Technology can complete 150 sample tests per hour, and a urine routine test may take only half a minute to get the results.

On December 7, 2021, at the Aiwei Technology production workshop assembly line, technicians were debugging the installed automatic microscopic inspection equipment. At the scene, the reporter saw that the equipment's parts were also very delicate, with the cover glass thickness being only 0.17 mm. Technicians had to repeatedly check the data on the computer system and debug the instrument parameters to ensure the accuracy of the equipment's detection. It is understood that the company's testing instruments have been installed in more than 5,000 hospitals nationwide.

Wonderful "Sky Eye", Rapid Tracking

According to normal reference values, the number of red blood cells in a microliter of urine sample in adult women is no more than 7.5, the number of white blood cells is no more than 13.5, and the number of epithelial cells is no more than 28. How to judge if the sample is abnormal? The first step is to check the pathological components such as red and white blood cells in the sample. According to international standards, the analysis of an uncentrifuged urine sample requires at least 6.4 microliters of sample volume. Under a high-power microscope, more than 300 lens fields of view are needed to complete the screening of one microliter of sample.

In the past era of mainstream manual microscopy, all results under the microscope needed to be manually judged, identified and counted. The labor intensity of the inspectors was high, and omissions and misjudgments were easy to occur. Moreover, due to subjective factors of the inspectors, the results could not be standardized.

How to solve the disadvantages of manual microscopy? The answer may be automation. In 2002, as the first urine sediment analyzer in China to obtain a registration certificate, the first-generation intelligent and automated urine sediment microscopic inspection product developed by Aiwei Technology can automatically collect images under a microscope and automatically identify and count red and white blood cells in urine, assisting manual microscopic examination.

"Our instrument has two microscope lenses. A low-power lens with a large field of view is used for comprehensive scanning and identification of large targets, and when small targets are found, it quickly switches to a high-power lens for magnification and identification." Aiwei Technology Vice General Manager Zhou Fengliang introduced that the two lenses work together flexibly, like two motorized eyes, which can quickly scan and analyze the pathological components in the sample. A single machine can complete 150 sample tests per hour, which is more than 15 times more efficient than manual microscopy.

At the production site, the reporter saw that the automatic microscopic inspection equipment also has very fine requirements for parts. In the flow counting pool used to place samples, the cover glass and cavity thickness is only 0.17 mm, which is equivalent to the thickness of 3 hairs.

"After the image is acquired, it will be automatically transmitted to the computer, and the saved images can be viewed at any time, which is beneficial for traceability and facilitates remote expert consultation." Zhou Fengliang introduced that artificial intelligence machine vision for microscopic inspection has brought significant improvements to medical testing work. The greatest significance of the instrument is that it solves the practical problems of large workload, unstable results, and inaccuracy in hospital testing work, and realizes the automation, standardization, and standardization of urine microscopic examination.

Original Innovation, Filling the Gap

"With the help of automation, the original urine samples that needed to be concentrated using a centrifuge can now be tested directly." Zhou Fengliang introduced that the automatic microscopic examination methodology created by his company eliminates the centrifugation step, shifting the industry focus from intelligent urine sediment analyzers to urine formed element analyzers. In 2007, because its automated microscopic examination series instruments do not require centrifugation of samples during testing, Aiwei proposed the new concept of "urine formed elements" and was the first to rename "intelligent urine sediment analyzer" to "urine formed element analyzer". The new name was included in the "National Medical Device Classification Catalog".

"We were the first to apply 'machine vision technology' to the morphological examination of clinical pathological specimens in medical and health institutions, filling the technical gap in the field of automated morphological examination of medical microscopes, and are original innovations in terms of technology routes, methods, and levels." Aiwei Technology Chairman Ding Jianwen introduced.

Today, automatic microscopic inspection technology has become the mainstream in the industry and is the "gold standard" for medical testing. "Now, Aiwei Technology's automatic microscopic inspection instruments can complete 90% of the workload of routine clinical specimen microscopic examination. Manual inspection only needs to review the results provided by the instrument to issue a confirmed report, and can provide morphological data analysis that is difficult to achieve manually." Ding Jianwen introduced, "Because it is the crystallization of the wisdom of many clinical testing experts, the massive clinical data behind it is completely confirmed by manual microscopic examination. We use automation and intelligence to realize manual microscopic examination and complete classic morphological microscopic examination."

Based on the original medical microscope automatic microscopic examination technology, Aiwei Technology has currently developed a series of medical testing instruments for fully automatic urine, feces, genital secretions, body fluids, and blood, filling many international and domestic technical gaps. The company also independently develops and produces reagents and medical consumables that match the testing instruments. The products are widely used in various medical and health institution testing departments. Among them, the company's testing instruments have been installed in more than 10,000 units domestically and internationally, and more than 5,000 hospitals nationwide.
