Abstract
Description
Technical Field
[0001] The utility model relates to the field of experimental instruments, in particular to a tissue embedding device. Background Art
[0002] A tissue embedding machine is a device that embeds human or animal and plant specimens in wax blocks after dehydration and wax immersion for histological diagnosis or research. It is usually used in medical schools, hospital pathology departments, medical research units, animal and plant research units, and food testing departments.
[0003] Existing tissue embedding machines place the tissue to be embedded in an open embedding cassette, which is then filled with melted paraffin. The cassette also serves as a mold for the finished wax block. However, when multiple embedding cassettes are processed simultaneously, cells or cell clumps may become entangled in the melted paraffin and drift outside the cassette, making them difficult to clean. These cells may also drift into other cassettes, causing contamination. This significantly limits the efficiency of this process, making high-throughput processing difficult. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned deficiencies of tissue embedding devices in the prior art and provides a high-throughput and contamination-proof tissue embedding device. The device disposes an embedding box in a partition frame, and utilizes the partition frame to divide the embedding cylinder into multiple areas. The partition frame prevents the embedded tissue in each area from floating into other areas, thereby avoiding contamination and achieving orderly high-throughput operation.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] The utility model discloses a high-throughput anti-pollution tissue embedding device, comprising an embedding machine main body, a partition frame and an embedding box body. The embedding machine main body is provided with an embedding cylinder, the partition frame is arranged in the embedding cylinder, a plurality of compartments for accommodating embedding boxes are provided in the partition frame, and limiting protrusions are provided on the four side walls of each compartment. The edge of the embedding box body is provided with a limiting edge for overlapping the limiting protrusions. When the embedding box body is placed in the compartment of the partition frame, the top edge of the embedding box body is lower than the top of the partition frame.
[0007] Preferably, the partition frame includes a plurality of vertically connected partition panels, and handles made of soft materials are provided on the two side partition panels located at the outermost edges.
[0008] Preferably, nine compartments are provided in the partition frame and arranged in a nine-square grid format.
[0009] Preferably, a plurality of supporting legs are provided at the bottom of the partition frame.
[0010] Preferably, a net bag is laid at the bottom of the partition frame.
[0011] Preferably, a hook is provided on the bottom edge of the partition frame, and the hook is used to fix the net bag.
[0012] Preferably, the net bag adopts a 100-200 mesh precision stainless steel screen.
[0013] Therefore, the present invention has the following beneficial effects: (1) the embedding cylinder is divided into multiple areas by a partition frame, and the partition frame prevents the tissue to be embedded in each area from floating to other areas, thereby avoiding contamination and achieving orderly high-throughput operation; (2) the legs are used to support the partition frame, and the gaps between the legs are used for the melted paraffin to flow at the bottom of the partition frame; (3) a net bag is provided at the bottom of the partition frame for recovering some of the tissue that floats out of the embedding box to prevent contamination of the embedding work in the next cylinder.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] like Figure 1 、 Figure 3 As shown, the present invention provides a high-throughput, contamination-resistant tissue embedding device, comprising an embedding machine body 1, a partition frame 3, and an embedding cassette 4. The embedding machine body 1 is provided with an embedding cylinder 2. The embedding cylinder 2 is a container for melted paraffin within the embedding machine body 1. In the prior art, the tissue to be embedded is placed within the embedding cassette 4, which is then placed into the melted paraffin within the embedding cylinder 2. The paraffin flows into the embedding cassette 4, embeds the tissue, and solidifies to form a tissue wax block. The embedding cassette 4 serves as a mold for the finished wax block and also as a place to hold the tissue to be embedded. However, the tissue to be embedded may contain detached cells or cell clumps that become attached to the melted paraffin and drift outside the embedding cassette, making it difficult to clean, or drift into other embedding cassettes, causing contamination.
[0020] like Figure 1 、 Figure 2 As shown, the partition frame 3 is disposed within the embedding cylinder 2. The partition frame 3 is provided with a number of compartments capable of accommodating the embedding cassettes 4. Each compartment has a limiting protrusion 301 on its four sidewalls. The edges of the embedding cassettes 4 are provided with limiting edges 401 for overlapping the limiting protrusions 301. Because the top edge of the embedding cassettes 4 is lower than the top of the partition frame 3 when placed within the compartments of the partition frame 3, the partition frame 3 can be used to divide the embedding cylinder 2 into multiple areas. The partition frame 3 prevents the embedded tissue in each area from floating into other areas, thereby avoiding contamination and achieving orderly high-throughput operation.
[0021] The partition frame 3 includes a plurality of vertically connected partitions, and the two side partitions at the edge are provided with soft material handles 302. The handles 302 can be made of soft materials such as rubber to facilitate the removal of the partition frame 3 without affecting the closing operation of the embedding cylinder 2.
[0022] The partition frame 3 is provided with 9 compartments arranged in a nine-square grid format.
[0023] The bottom of the partition frame 3 is provided with a plurality of legs. The legs are used to support the partition frame 3. At the same time, the gaps between the legs allow the melted paraffin to flow through the bottom of the partition frame 3. Since the melted paraffin flows through the bottom, it can further prevent the tissue in the embedding box 4 from drifting.
[0024] A net bag 5 is placed at the bottom of the partition frame 3. Hooks 303 are provided on the bottom edge of the partition frame 3 to secure the net bag 5. The net bag is made of a 100-200 mesh precision stainless steel screen, commonly used in laboratory cell strainers. This material is commonly used in the field and will not be described in detail here. When removing the partition frame 3, some tissue that floats out of the embedding cassette 4 will be caught by the net bag 5. This tissue will be recovered to prevent contamination of the next embedding tank.
