【Preface】Zhengzhou Zhongpu Medical Equipment Co., Ltd. is a high-tech enterprise focusing on the research and development, production and sales of tuberculosis smear, acid-fast dyeing, intelligent scanning products. The company has a number of national invention patents for tuberculosis smears diagnostic technology, and is one of the enterprises with the most complete product categories and the most mature technology of tuberculosis smears, acid-fast dyeing, intelligent scanning. The company launched the fully automatic tuberculosis smear intelligent scanning scanner, which is a new generation of tuberculosis smear intelligent scanning and diagnostic equipment independently created by Zhengzhou Zhongpu after 4 years. It has the obvious characteristics of extremely fast scanning speed, high accuracy, and flux upgrade in the original machine.

Depth analysis

A machine was used to realize simultaneous scanning of Zigny's staining and fluorescence staining

One machine provides two TB staining scans, which is especially suitable for use by CDC at all levels and is of great significance for quality supervision of regional TB laboratories!

As we know, there are two kinds of tuberculosis smear staining at present: one is Zigny's acid-fast staining represented by "compound red" and "methylene blue", the other is fluorescent acid-fast staining represented by "auramine O", and the corresponding scanning microscopy is ordinary microscopy with bright field light source and fluorescence microscopy with dark field light source.

Both staining methods have their own advantages

Q1

【Zigny's stain scan】：The 100-times oil lens scanning microscopy, due to high magnification and good staining specificity, can observe the knobbly details of mycobacterium tuberculosis, and the morphological diagnosis specificity of mycobacterium tuberculosis is quite good, so we dare to report positive even if one bacterium is found. However, because the 100-times oil lens scanning is used, the scanning area is limited, and the area of the whole film is too small. Making it less sensitive to scan.

Q2

【 Fluorescent staining scan 】 : The scanning area is many times larger than that of 100 times because of the 20-fold scanning field; the scanning area is greatly improved and the sensitivity of the scanning is also improved because the scanning area is greatly improved and the sensitivity of the scanning is also improved because only 40-fold scanning field is used to observe the tuberculosis bacilli and impurities. It affects the improvement of its specificity, so the results of fluorescence reporting are generally more than 5-7 to report positive results.

Because the two staining methods and scanning microscopy have their own advantages, diagnostic doctors also have different understandings, so there are two methods of scanning microscopy - Zioni's scanning microscopy and fluorescence scanning microscopy.

At present, most manufacturers only provide one scanning method, either Ziezini's scan or fluorescence scan. Since the CDC at all levels needs to conduct regular supervision on the quality of regional tuberculosis laboratories, it is often necessary to purchase two different scanners.

Zhengzhou Zhongpu research and development team in-depth analysis of the differences between the two scanning methods and the respective advantages of the two methods, at the beginning of product design, thinking from the design source innovatively proposed two-in-one scanning mode, truly achieve the dual use of one machine, and no manual toggles to switch the light source. This scanning method can meet the needs of different users, especially the CDC laboratory for tuberculosis laboratory supervision work, without the need to purchase two different scanners, reducing procurement costs, greatly saving resources.

Technical comparison：

Zhengzhou Zhongpu tuberculosis smear intelligent scanner:One machine dual-use, automatic switching light source, no manual toggle switch light source, reduce procurement costs.Provide faster and more scanning area Settings, to improve the positive rate of film reading to provide a higher possibility.

General scanner:One machine, high procurement cost, can not meet the supervision of CDC laboratory dyeing needs of different. Although some provide a machine dual-use function, but the need to manually switch the light source, operation trouble.

Provides different scanning modes for different users —— Suitable for use and research

We use a dual-use scanning mode, automatic light source switching operation, is to meet the needs of different users more thinking!

Zhengzhou Zhongpu Tuberculosis intelligent film reading dual scanner, can meet the needs of different users at the same time, suitable for supervision, development and application, bring better user experience, lower procurement costs.

This issue of "tuberculosis Ziezini's staining scanner technology introduction series of special topics" has been introduced, the above for you in-depth analysis of the current tuberculosis smear staining scanning technical difficulties, introduced the characteristics of Zhengzhou Zhongpu tuberculosis smear intelligent scanning scanner and practical application of benefits for users, hope to help you out of the misunderstanding, out of the confusion, To improve the understanding of tuberculosis smear intelligent reading. Zhengzhou Zhongpu help improve tuberculosis smear detection smear positive rate! At the same time also hope to help the industry better development!

——Technology without boundaries, wisdom endowed the future——

Zhongpu people do not forget the original intention, standing in the user's point of view, ingenuity to create, to benefit users - to provide you with truly reliable products!! It is hoped that the intelligent scanning products will be popularized to all medical units and scientific research institutions as soon as possible, benefiting patients and families. Zhengzhou Zhongpu will escort human health!
