Sample smear coating dryness fraction detection method, apparatus and sample smear drying apparatus

Abstract

The application provides a sample smear coating dryness fraction detection method and an apparatus. Concretely, a sample coating covering area on a sample smear is employed in a light irradiation process, an effective photoelectric signal used for characterizing the effective optical signal intensity is generated based on a real-time detected optical signal, and then whether the coating is dry is determined by analyzing the effective optical signal after being affected by a blood film. The dryness fraction of each sample smear can be independently detected, thus time consumption based on the longest sample smear drying time is avoided and also the drying quality of each sample smear is guaranteed. The application also discloses a sample smear drying apparatus realizing the above method, and aiming at the sample smear in the drying process, whether the blood film is dried is determined by employing the method of enabling light to irradiate the sample coating on the sample smear.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a method and device for detecting the drying degree of a sample smear coating, and a sample smear drying device. Background technique [0002] The process of preparing a blood smear by an automatic pusher includes steps such as dripping blood, pushing the slide, drying, and staining. After the blood sample to be analyzed is dropped on the blood smear and pushed into a thin blood film, the blood smear needs to be placed in a drying box, and the drying unit will dry and dehydrate the blood film of the blood smear with hot air, and wait for the blood film to completely dry. After drying, it can be taken out and put into the dyeing box for dyeing. If the blood film is immersed in the dye solution before it is completely dried, problems such as deformation, shedding, and uneven staining of the blood film will occur, resulting in the failure of the preparation of the blood sme...

AI Technical Summary

Problems solved by technology

Since the degree of dryness of the blood film of the blood smear is unknown, in order to prevent the blood film from being put into the dye solution without drying, in the prior art, the drying unit is usually used to dry the blood smear in the drying box. It is carried out at a preset time, which is not conducive to the drying process in the process of preparing blood smears: on the one hand, due to the difference in the thickness of the blood film of blood smears, some blood smea
