Abstract
Description
Technical Field
[0001] This invention relates to the field of cell preparation technology, and more particularly to an inclined pipetting structure for a cell preparation staining machine. Background Technology
[0002] Cell preparation and staining is a key technique in cytological diagnosis. By preparing and staining cell samples, the morphology and structure of cells are revealed, providing a basis for disease diagnosis. The procedure involves sample collection, preparation, and staining. Sample collection includes tissue biopsy and body fluid collection, which must adhere to aseptic principles. Preparation methods include smear preparation and slide preparation. Liquid-based thin-layer preparation can remove impurities and optimize cell distribution. The staining process utilizes different staining agents to combine with cellular components. Commonly used staining methods include Wright's stain, Giemsa stain, Papanicolaou stain, and immunohistochemical staining, which are applied in hematology, gynecological cytology, and tumor diagnosis, respectively. In the medical field, cell preparation and staining assist pathologists in diagnosing diseases, determining the nature of tumors, and detecting pathogens, providing a reference for treatment and prognosis assessment. It is widely used in hospital pathology departments, laboratories, and research institutions, promoting the development of medical research and clinical diagnosis and treatment. With the development of medical technology, the requirements for the automation and operational precision of cell preparation and staining machines are increasing. Among them, the pipetting structure, as a key component of the cell preparation and staining machine, plays a decisive role in the sample processing effect.
[0003] However, existing cell slide staining machines mostly use vertical pipetting, which has many drawbacks in practical applications. On the one hand, vertical pipetting makes it difficult to distribute cells evenly in the sample, and the staining solution cannot fully and evenly cover the cells, resulting in poor staining effects and affecting the observation of cell morphology and structure. On the other hand, vertical pipetting results in poor liquid flow, making it easy for impurities in the sample to accumulate, reducing the purity of cell slides and interfering with pathological diagnosis. Currently, new devices that can precisely control pipetting parameters through intelligent control modules, apply microfluidic technology to achieve precise cell manipulation and even distribution, and use advanced imaging technology to assist in optimizing sample processing methods are improving the problems of traditional vertical pipetting. Although society has improved traditional vertical pipetting through intelligent equipment upgrades and microfluidic technology innovations, certain problems still exist. While intelligent equipment can precisely control pipetting parameters, the high cost of the equipment makes it unaffordable for some primary healthcare institutions, limiting its widespread adoption.
