Tissue chip receptor blank wax block preparation instrument

Abstract

The invention provides a tissue chip receptor blank wax block preparation instrument, which comprises an upper cover (100), a sliding block (200) and a supporting base (300), wherein a first guide hole (301) is formed in the supporting base (300), the first guide hole (301) is provided with a demolding block (304) moving along the first guide hole (301), a second guide hole (302) is formed in thesupporting base (300), a vertical rod (103) moves up and down along the second guide hole (302), the vertical rod (103) is fixed to a top plate (104), and the upper surface of the top plate (104) canabut against the lower surface of the demolding block (304). Due to the fact that array columns (202) are transversely arranged rather than longitudinally arranged, a wax liquid can be attached to theside surface of the sliding block (200) to form a flat plane, thus animal and plant tissue chips and agentia can be conveniently arranged in concave holes of wax blocks, experiment operation is facilitated, and experiment results are not affected.

Description

technical field [0001] The invention relates to a medical experiment appliance, in particular to a preparation instrument for making tissue chip acceptor blank wax blocks. Background technique [0002] Tissue chip (tissue chip), also known as tissue microarray (tissue microarrays), is an important branch of biochip technology, which is to arrange many different individual tissue samples in a regular array on the same carrier (such as blank wax block) In situ histological studies of indicators. [0003] For tissue chip research, it is usually necessary to configure it on a receptor blank block with multiple holes for research. [0004] Usually the acceptor blank block is made on site, because the preservation of the block is more difficult. [0005] Background technology, Chinese invention patents: 201510037073.2, tissue chip receptor blank wax block preparation apparatus and its use method; 201611097683.2, plant tissue slice receptor blank wax block preparation apparatus, ...

[0005] Background technology, Chinese invention patents: 201510037073.2, tissue chip receptor blank wax block preparation apparatus and its use method; 201611097683.2, plant tissue slice receptor blank wax block preparation apparatus, which all use the blank made by the array column with up and down movement Wax block, and because it needs to utilize too dense array column to lean against relatively viscous wax liquid, and causes the upper surface of blank wax block, just is provided with the surface of a plurality of concave holes uneven, is unfavorable for animal, plant The placement of the tissue chip and the placement of the drug may have an impact on the experimental results
