Description

Technical Field

[0001] The utility model relates to the technical field of medical detection auxiliary operation devices, in particular to a pathological tissue specimen storage device. Background Art

[0002] The specimens sent by the pathology department include tissue specimens and cell specimens. Tissue specimens are human tissues and are closely related to surgery. Pathological tissue specimens are generally living tissues obtained through surgery, endoscopy, and coarse needle puncture, such as the appendix removed due to appendicitis, the gallbladder removed due to gallstones, and the colon, breast, and uterus removed due to tumors. Pathological tissue specimens need to be made into slices through complex pathological techniques. Pathologists make the final diagnosis of the disease based on the slices, combined with imaging changes and clinical history, and guide clinical treatment. Cytology specimens include puncture cell smears, urine, gynecological cervical cell specimens, joint fluid, cerebrospinal fluid, serous cavity effusion, etc. Fine needle aspiration smears, nipple discharge smears and other clinically prepared smears need to be immediately placed in 95% alcohol for fixation, such as thyroid puncture cell smears. Other cytology specimens should be sent to the pathology department in time for processing and made into cell slides after they are collected.

[0003] Specimens are the basic materials for pathological diagnosis and are very important. Specimens need to be fixed and processed in time after leaving the human blood supply to maintain the integrity of tissue structure, protein, cell DNA and RNA. Fixation is to preserve specimens so that all substances and genetic information in tissue cells can be preserved and consistent with the state of the specimen when it is alive. If the specimen is not fixed in time or inappropriately, it will cause tissue corruption, autolysis, loss of antigens and genetic materials. The damage to the specimen is irreversible and irreparable. First of all, it will affect the quality of the slices. The tissue structure is unclear under the microscope, and the cell morphology cannot be judged, resulting in difficult or impossible diagnosis. It will also affect the accuracy of immunohistochemistry and genetic testing results, not to mention the guiding value of precision treatment. Therefore, timely dissection and fixation, and sufficient fixation time of fixative are very important and are also the prerequisite for accurate diagnosis.

[0004] At present, most hospital laboratories and third-party in vitro testing institutions use specimen bags or specimen bottles for specimens. In order to maintain the stability of the structure, morphology and chemical composition of biological cell and tissue samples, specimen fixatives need to be added to the specimen bags or specimen bottles. These fixatives fully infiltrate specimens such as sliced ​​tissues to fully fix them. Then operations such as staining, embedding and slicing can be performed to observe and study biological tissue cells. In general, the fixative in the specimen bag or specimen bottle is 5-20 times the specimen tissue. For small specimen tissues (such as gastrointestinal endoscopy, biopsy, puncture and other tissues), a large amount of fixative will make it difficult for doctors to find small specimen tissues when taking samples, and it is even more difficult to remove tissues from a large amount of fixative. For large specimen tissues, the amount of fixative used is more, and due to the large volume of specimen tissues, this will cause the fixative to be more likely to become turbid, which is difficult to distinguish when taking samples, and then lead to the omission of small tissues containing lesions in large specimens, resulting in inaccurate sampling. In addition, during the specimen collection process, the integrated specimen bag or specimen bottle can easily cause the fixative to be taken out with the specimen and pollute the environment (the fixative often contains toxic reagents such as formaldehyde).

[0005] Therefore, it is necessary to improve and innovate the existing specimen bags or specimen bottles. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings. The following embodiments are only specific embodiments cited in this application to illustrate the technical solution of the present application, rather than to limit it, and the scope of protection of the present application is not limited thereto. In the description of the utility model, it should be noted that the orientation or positional relationship indicated by the terms "inside" and "outside" is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] The utility model provides a pathological tissue specimen storage device, see Figure 1 to Figure 4 As shown. It includes an upper storage part 1 and a lower storage part 2 which are detachably connected; wherein:

[0032] The bottom of the upper storage body 1 is cylindrical and is movably connected to the top of the lower storage body 2; the top of the upper storage body 1 is tubular and is movably connected to an upper cover 20 for sealing. Figure 1 to Figure 3 As shown. This design is an improvement on the specimen bottle. In another embodiment, the top of the upper storage body 1 is bag-shaped and is provided with a zipper or sealing strip 19 for sealing. Figure 4 This design is an improvement on the specimen bag.

[0033] The lower storage part 2 is provided with a detachably connected double-layer filter screen inside, wherein the first through hole 4 on the upper filter screen 3 and the second through hole 6 on the lower filter screen 5 have the same aperture and are distributed in the same manner, for example, the apertures of the first through hole 4 and the second through hole 6 are both 3 mm. The upper filter screen 3 and the lower filter screen 5 can rotate relative to each other, so that the first through hole 4 on the upper filter screen 3 and the second through hole 6 on the lower filter screen 5 are staggered, partially overlapped, or completely overlapped; when the first through hole 4 and the second through hole 6 are staggered, the aperture of the filter screen is completely exposed, and through the relative rotation of the double-layer filter screen, when the first through hole 4 and the second through hole 6 partially overlap, it is equivalent to reducing the filtration aperture of the double-layer filter screen, which can be applied to the separation of tissues and fixatives of specimens of different sizes, the tissues are retained on the filter screen, and the fixative reaches the bottom of the lower storage part 2 through the filter screen.

[0034] In order to ensure that the fixative flows out smoothly, the inner bottom end of the lower storage body 2 is provided with an inclined surface 7, and the lowest point of the inclined surface 7 is connected to a liquid outlet 8. The liquid outlet 8 is closed by a cover 21 or connected to a waste liquid bucket by a hose. When the pathological tissue specimen storage device needs to be stored or transported, the upper cover 20 or the zipper or the sealing strip 19 and the cover 21 are closed; when the pathological tissue specimen storage device needs to separate the tissue from the fixative, the cover 21 can be opened and connected to the waste liquid bucket by a hose to prevent the fixative from leaking and polluting the environment. In order to improve the filtration efficiency, the top of the upper storage body (1) can be pressurized. For example, for a bottle-type structure, open the upper cover 20 and connect a pressurizing device to pressurize; for a bag-type structure, when the zipper or the sealing strip 19 is closed, the filtration can be promoted by squeezing the upper liquid.

[0035] In order to facilitate the disassembly, installation, cleaning and replacement of the upper filter screen 3 and the lower filter screen 5, in a preferred embodiment, the lower storage sub-body 2 includes a detachably connected first sub-body 9 and a second sub-body 10, the top of the first sub-body 9 is movably connected to the bottom of the upper storage sub-body 1, and the bottom of the first sub-body 9 is movably connected to the second sub-body 10. The specific connection method can be threaded connection, and a sealing gasket can be provided at the connection. The upper filter screen 3 is located in the first sub-body 9, and the lower filter screen 5 is located in the second sub-body 10.

[0036] In order to facilitate the collection of materials after the fixed liquid is filtered out, in a preferred embodiment, the upper filter screen 3 is bowl-shaped, the tissue is located in the bowl, and the first through hole 4 on the upper filter screen 3 is located on the bottom wall of the upper filter screen 3; in order to improve the sealing and stability, the top edge of the upper filter screen 3 is coated with a first rubber pad 11 on the outside, and the edge of the upper filter screen 3 is clamped on the first clamping groove 12 at the upper end of the first split body 9. The upper filter screen 3 is connected to the first split body 9 through an interference fit through the first rubber pad 11. When the upper filter screen 3 is taken out, it can be pulled out with a little force based on the elasticity of the first rubber pad 11.

[0037] In order to fit the upper filter screen 3 tightly, in a preferred embodiment, the lower filter screen 5 adopts a flat plate structure, and the lower filter screen 5 is close to the bottom of the upper filter screen 3. In order to improve the sealing and stability, the outer side of the edge of the lower filter screen 5 is covered with a second rubber pad 13, and the edge of the lower filter screen 5 is clamped on the second clamping groove 14 at the upper end of the second split body 10. The lower filter screen 5 is connected to the second split body 10 through the second rubber pad 13 by interference fit. When the lower filter screen 5 is taken out, it can be pulled out with a little force based on the elasticity of the second rubber pad 13.

[0038] In order to facilitate the rotation of the lower filter screen 5 relative to the upper filter screen 3, and thus achieve the effect of adjusting the filtration aperture of the double-layer filter screen, in a preferred embodiment, a connecting rod 15 is connected to one side of the lower filter screen 5, and the connecting rod 15 passes through the third through hole 16 on the side wall of the second split body 10 and is connected to the toggle plate 17 located outside the second split body 10. For example, a connecting rod with a thread and a lower filter screen 5 with a screw hole can be used for connection. Alternatively, the connecting rod 15 and the toggle plate 17 are movably connected. When the lower filter screen 5 needs to be taken out, the connecting rod can be first unscrewed from the outside of the second split body 10 or only the toggle plate 17 can be removed, and then the lower filter screen 5 can be taken out from the second split body 10.

[0039] Specifically, the third through hole 16 is a long hole. During operation, by moving the toggle plate 17 left and right, the lower filter screen 5 can be rotated relative to the upper filter screen 3. In order to improve the airtightness, a third rubber pad 18 is installed in the third through hole 16 for the connecting rod 15 to pass through. The third rubber pad 18 has a straight opening, which ensures that the toggle plate 17 can move left and right while also playing a sealing role, and cooperates with the second rubber pad 13 to further improve the sealing effect.

[0040] The pathological tissue specimen storage device provided by the utility model is convenient for separating tissue from fixative through the design of a double-layer filter screen, so that the tissue remains on the filter screen; at the same time, the upper and lower split design of the storage device further facilitates tissue removal, improves the efficiency of doctors in obtaining specimens, and avoids missing specimens; the double-layer filter screen can rotate relative to each other, and the filter aperture size can be adjusted to meet different tissue filtration requirements; in addition, after the fixative is filtered out through the double-layer filter screen, it can be connected to a waste liquid barrel through a soft connection to ensure effective collection of the waste liquid and avoid environmental pollution caused by leakage of the fixative.
