Description

Technical Field

[0001] The utility model belongs to the technical field of tissue specimen processing research, and more specifically, particularly relates to a tissue fixative sampling device. Background Art

[0002] In biological research, tissue specimens often need to be fixed to ensure the integrity of the tissue specimens so that researchers can perform subsequent staining, immunohistochemistry and other operations. Generally speaking, tissue specimens are fixed by placing them in a tissue fixative, and a common tissue fixative is formalin fixative. Taking formalin fixative as an example, the formaldehyde in the formalin fixative reacts with the amino groups in the proteins in the tissue specimens to coagulate the proteins, thereby better preserving the antigenicity and fine structure of the tissue. In addition, formalin fixative has strong permeability and good fixation effect, which can meet the requirements of conventional HE, immunohistochemistry, in situ hybridization and other detection work.

[0003] Based on the above, the inventors have discovered the following problems: In current biological research, tissue fluid is usually required for testing. However, when sampling, the liquid is easily spilled outside and is inconvenient to clean, polluting the environment. If it is a volatile toxic liquid, it can cause malformations and carcinogenesis, causing great harm to the human body.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a tissue fixative sampling device is provided to achieve a purpose with greater practical value. Utility Model Content
