Description

Technical Field

[0001] The utility model relates to a device for making paraffin sections of biological tissue specimens, in particular to an automatic embedding device of a tissue dehydrator, which is widely used in the fields of medical clinical pathology, cytological examination and biological research. Background Art

[0002] In existing technology, the paraffin sectioning process for biological tissue samples primarily involves two steps: tissue dehydration and tissue embedding. While the term "tissue dehydration" is often used in the industry to abbreviate this process, it actually encompasses both tissue dehydration and tissue clearing. Currently, most companies, both domestically and internationally, have developed automated tissue dehydrators and automated tissue embedding machines for these two steps, respectively, to meet the processing needs of biological tissue samples.

[0003] However, most existing automated equipment can only perform tissue dehydration or tissue embedding independently; there is no device in the domestic market that can handle both steps simultaneously. Lab technicians often need to operate two devices to complete tissue sample processing, which not only increases equipment procurement and maintenance costs but also requires manual intervention to connect the two steps, reducing work efficiency.

[0004] Furthermore, switching between two independent processes can lead to misidentification of tissue samples or confusion in labeling, potentially causing medical accidents. Furthermore, switching between independent devices can easily lead to reagent volatilization, increasing environmental pollution and potentially impacting air quality and worker health. Therefore, developing a fully automated device capable of dehydrating and embedding tissues is crucial and urgent. Summary of the Invention
