[0002] A smear applicator for medical examination is a tool used to make smears, usually made of plastic or metal. The main function of a smear applicator is to make smear samples when performing cytological examinations in the laboratory. Smear is a common cytological examination method. Patient samples (such as blood, urine, body fluids, etc.) are smeared on a glass slide, and then the sample is evenly spread on the slide with a smear applicator. Finally, the cell morphology, structure and quantity are observed through staining and other methods to diagnose and treat diseases. Smear applicators usually have a certain size and shape, which can easily spread the sample on the slide and maintain the uniformity and consistency of the smear. The use of a smear applicator can improve the quality and reliability of smears, reduce operator errors, and also speed up the speed and efficiency of laboratory testing.
