Automatic sputum smear staining instrument for medical use and staining method thereof

Abstract

The invention discloses a medical self-sputum smear dyeing device and method instead of artificial operation in the tuberculosis detection technique domain, which comprises the following parts: three-dimensional right-angle coordinate mechanical console, cam, smear operation head, dyeing liquor sprayer, sampling tag box component, sample box location board, slide location rack, pusher box, creeping pump group, and display and operation button. The method comprises the following steps: finishing automatic box opening, shooting and image display; selecting the suspected part of sputum sample artificially; gathering the sample to coat on the slide; dying and drying fractionally; preparing the smear sputum sample to satisfy the microscopic requirement. The invention prevents the detecting personnel from infection and medical pollution, which improves the quality of sputum smear and shortens the sample disposal time.

Description

technical field [0001] The invention belongs to the technical field of tuberculosis inspection, and in particular relates to an automatic sputum smear dyeing apparatus and a sputum smear dyeing method for tuberculosis prevention and treatment. Background technique [0002] Sputum smear is an important test method for tuberculosis prevention and diagnosis and treatment, and its diagnostic value has an irreplaceable status by other methods. The National Center for Disease Control (CDC) Tuberculosis Control Center has strict operating regulations for sputum smears. The "Direct Sputum Smear Examination Method" and "Implementation Method for Quality Assurance of Sputum Smear Microscopic Examination" promulgated in recent years are important measures to unify the operation methods and ensure the quality of inspection by tuberculosis prevention and control institutions at all levels. [0003] However, due to the particularity of sputum smear and the limitation of manual operation, ...

AI Technical Summary

Problems solved by technology

[0004] 1. It has a greater impact on the health of sputum test workers

[0005] Because there are a large number of viruses and germs lurking in the sputum sample, especially the drug-resistant Mycobacterium tuberculosis is a great danger to the health of the inspectors. During the manual operation, they will inevitably come into close or even zero-distance contact with the sputum, causing infection. The possibility of TB is greatly increased, and many data show that the incidence of tuberculosis of sputum test personnel is higher than that of other medical personnel

[0006] 2. Because the smell, color and shape of the sputum sample bring a lot of sensory discomfort to the operators, they are unable to pick suspicious samples in some cases and cannot strictly implement the operating regulations, thus affecting the results of microscopic examination

[0007] 3. Sputum often causes iatrogenic pollution during natural drying or heating

[0008] 4. The sample processing time is long and the operation is complicated. At present, most sputum often takes more than 12 hours to dry naturally, and it takes more than an hour to dry after staining, which affects the reporting time of the results.

[0009] 5. Poor repeatability of operation

[0010] 6. The time of staining is random, which may easily cause difficulties in microscopic examination
