Abstract

The invention provides an induced sputum eosinophilic granulocyte counting instrument, which comprises a warm bath device, a reagent pump device, a pipetting device, a flow counting chamber device, a detection device and a control system, and is characterized in that the warm bath device is used for placing a specimen container, and the specimen container is used for bearing induced sputum and a liquefaction reagent thereof; the reagent pump device comprises a liquid mixing container and a first pump machine, and the first pump machine is used for pumping a reagent into the liquid mixing container; the pipetting device is used for transferring a reagent in the liquid mixing container into the specimen container or transferring a specimen in the specimen container into the liquid mixing container; a liquid carrying device comprises a counting plate and a second pump machine, the counting plate is communicated with the liquid mixing container, and the second pump machine is used for pumping a specimen and reagent mixture in the liquid mixing container into the counting plate and flowing out of the counting plate; the detection device shoots an image of the counting plate to calculate the number and proportion of eosinophilic granulocytes; the induced sputum eosinophilic granulocyte counting instrument disclosed by the invention can be used for automatically detecting the number and the proportion of the induced eosinophilic sputum granulocytes.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and more specifically relates to an induced sputum eosinophil counter. Background technique [0002] Induced sputum detection, as a non-invasive, safe and reliable evaluation method for airway inflammation, is being paid more and more attention to and utilized. In diseases such as asthma, chronic bronchitis, and interstitial pneumonia, patients all have airway inflammation. In the past, airway inflammation was usually evaluated by fiberoptic bronchoscopy, but because this examination is invasive, it is difficult to repeat. Therefore, inducing sputum is an important method. [0003] Normal sputum cells are mainly phagocytes and neutrophils, eosinophils and lymphocytes are less common. Eosinophils are a very important inflammatory cell in the body of asthma patients, and eosinophilia is a characteristic sign of bronchial asthma, eosinophilic bronchitis, cough variant asthma and allergic disea...
