Description

Technical Field

[0001] The utility model relates to the technical field of medical consumables, in particular to a pathological biopsy tissue specimen bottle. Background Art

[0002] A biopsy is a medical diagnostic procedure that involves removing a small sample of diseased tissue for pathological examination to help doctors understand the nature, extent, and severity of the lesion. Biopsies are crucial for diagnosing both neoplastic and non-neoplastic diseases, differentiating between benign and malignant tumors, and assessing the extent of disease progression.

[0003] Existing biopsy tissues are first stored in a storage bottle containing a formalin fixative solution, which serves to store the solution and fix the biopsy tissue. However, when the tissue needs to be examined, the small size of the biopsy tissue and the narrow mouth of the storage bottle make it difficult to remove the tissue from the formalin fixative solution, making it difficult to access the tissue. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems in the prior art. To this end, the utility model proposes a pathological biopsy tissue specimen bottle, which can facilitate the removal of tissue blocks.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A pathological biopsy tissue specimen bottle comprises: a bottle body, having a accommodating cavity with an upper opening, a bearing structure provided on the peripheral wall of the accommodating cavity, a bearing surface provided on the upper end of the bearing structure, the distance between the bearing surface and the bottom wall of the accommodating cavity being greater than the distance between the bearing surface and the upper end surface of the bottle body; an inner layer bottle, embedded in the accommodating cavity, the inner layer bottle having an upper opening, a filter hole provided on the bottom of the inner layer bottle, the inner layer bottle having a first supporting surface and a second supporting surface, the first supporting surface being higher than the second supporting surface, and one of the first supporting surface and the second supporting surface being in contact with the bearing surface; a bottle cap, detachably connected to the upper end of the bottle body, for sealing the inner layer bottle in the accommodating cavity.

[0007] Furthermore, the supporting structure is a protrusion protruding from the peripheral wall of the accommodating cavity, the outer peripheral wall of the inner layer bottle is provided with an avoidance groove, the lower end of the avoidance groove extends to the bottom surface of the inner layer bottle, the first supporting surface is the upper end surface of the avoidance groove, and the second supporting surface is formed at the bottom of the inner layer bottle.

[0008] Furthermore, there are multiple groups of protrusions and avoidance slots arranged circumferentially.

[0009] Furthermore, the upper end surface of the inner bottle is provided with a lifting column extending upward; when the first supporting surface contacts the load-bearing surface, the upper end of the lifting column is higher than the upper end surface of the bottle body.

[0010] Furthermore, a lifting head having a profile larger than that of the lifting column is provided at the upper end of the lifting column.

[0011] Furthermore, a threaded section is provided on the outer peripheral wall of the upper end of the bottle body, and the bottle cap is threadably connected to the threaded section.

[0012] Furthermore, the bottom wall of the threaded section is provided with an outwardly protruding convex ring, and the convex ring is used to abut against the bottom of the bottle cap.

[0036] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a pathological biopsy tissue specimen bottle, which includes a bottle body 100, an inner bottle 200 and a bottle cap 300.

[0037] The bottle body 100 has a accommodating cavity 110 with an upper opening, and a supporting structure 120 is provided on the peripheral wall of the accommodating cavity 110. The upper end of the supporting structure 120 has a supporting surface 130. The distance between the supporting surface 130 and the bottom wall of the accommodating cavity 110 is greater than the distance between the supporting surface 130 and the upper end surface of the bottle body 100, so as to facilitate the leakage of more inner bottles 200.

[0038] The inner bottle 200 is inserted into the accommodating chamber 110. The inner bottle 200 has an opening at the top and a filter hole 210 at the bottom. In some embodiments, the filter hole 210 may also be provided on the wall of the inner bottle 200 to allow liquid to quickly drain out of or enter the inner bottle 200. The diameter of the filter hole 210 may be 3-5 mm. For example, in this embodiment, the diameter of the filter hole 210 is 4 mm. The inner bottle 200 has a first supporting surface 220 and a second supporting surface 230. The first supporting surface 220 is higher than the second supporting surface 230. Either the first supporting surface 220 or the second supporting surface 230 contacts the support surface 130. When the first supporting surface 220 contacts the support surface 130, the height of the inner bottle 200 is lower than when the second supporting surface 230 contacts the support surface 130. The bottle cap 300 is detachably connected to the upper end of the bottle body 100 , and the bottle cap 300 is used to seal the inner bottle 200 in the accommodating cavity 110 .

[0039] The bottle cap 300 is detachably connected to the upper end of the bottle body 100 , and the bottle cap 300 is used to seal the inner bottle 200 in the accommodating cavity 110 .

[0040] The utility model provides a pathological biopsy tissue specimen bottle, such as Figure 1 and Figure 2As shown, when storing, the first supporting surface 220 is supported on the carrying surface 130, the inner bottle 200 is in a low position, and the tissue in the inner bottle 200 is immersed in the formalin fixative solution of the accommodating cavity 110, thereby storing the pathological tissue; when it needs to be taken out, the bottle cap 300 can be removed and the inner bottle 200 can be lifted so that the second supporting surface 230 is supported on the carrying surface 130, achieving the following Figure 6 and Figure 7 In the state shown, since the first supporting surface 220 is higher than the second supporting surface 230, the inner bottle 200 is in a high position when the second supporting surface 230 is supported on the bearing surface 130, and the inner bottle 200 is separated from the formalin fixative solution. Due to the existence of the filter hole 210, the liquid in the inner bottle 200 will also be discharged into the receiving chamber 110, and only the pathological tissue will be left in the inner bottle 200. Therefore, when the pathological tissue is taken out, it will not be disturbed by the formalin fixative solution, and the sampling is simple and convenient. At the same time, the inner bottle 200 does not need to be completely removed from the receiving chamber 110, and the inner bottle 200 does not need to be completely removed. This avoids residual liquid from falling when the inner bottle 200 is completely removed and contaminating the work surface.

[0041] Reference Figure 2 and Figure 5 In some embodiments of the present invention, the supporting structure 120 is a protrusion protruding from the peripheral wall of the accommodating cavity 110. The outer peripheral wall of the inner bottle 200 is provided with an avoidance notch 240, the lower end of which extends to the bottom surface of the inner bottle 200. The first supporting surface 220 is the upper end surface of the avoidance notch 240, and the second supporting surface 230 is formed at the bottom of the inner bottle 200. Specifically, the second supporting surface 230 is an annular surface at the bottom edge of the inner bottle 200. The protrusion can be embedded in the avoidance notch 240 and contact the upper end surface (first supporting surface 220) of the avoidance notch 240, thereby avoiding structural interference. When pathological tissue needs to be removed, the inner bottle 200 can be lifted until the protrusion (supporting structure 120) is disengaged from the avoidance notch 240. The inner bottle 200 can then be rotated to misalign the protrusion (supporting structure 120) and avoidance notch 240, allowing the support surface 130 to contact the bottom of the inner bottle 200 (the second supporting surface 230). This temporarily lifts the inner bottle 200, facilitating the filtration of the liquid inside and the removal of the pathological tissue. Typically, the bottom opening of the avoidance notch 240 is relatively small. When the second supporting surface 230 contacts the bottom of the inner bottle 200 (the second supporting surface 230), rotating the inner bottle 200 within this small area makes it difficult to realign the misaligned protrusion (supporting structure 120) and avoidance notch 240, resulting in the inner bottle 200 falling. In addition, in order to extract the inner bottle 200 smoothly, there is a certain gap between the outer wall of the inner bottle 200 and the wall of the accommodating cavity 110, such as a gap of 0.5 mm, which does not affect the position stability of the inner bottle 200 and makes the extraction of the inner bottle 200 smoother.

[0042] In a further embodiment of the present invention, multiple groups of protrusions (supporting structures 120 ) and avoidance slots 240 are arranged circumferentially, thereby providing multi-position support and making the support more stable.

[0043] Reference Figure 3 、 Figure 4 and Figure 8 In some embodiments of the present invention, a lifting column 250 extending upward is provided on the upper end surface of the inner bottle 200. When the first supporting surface 220 contacts the bearing surface 130, the upper end of the lifting column 250 is higher than the upper end surface of the bottle body 100. Therefore, when the inner bottle 200 is in a low position, the inner bottle 200 can be lifted by pinching the lifting column 250, which makes the operation more convenient. Figure 2 As shown, the bottle cap 300 is provided with a groove with an opening at the bottom to cover the upper end of the bottle body 100. The depth of the groove is sufficient so that when covering the upper end of the bottle body 100, the bottle cap 300 will not interfere with or contact the lifting column 250, so that the lifting column 250 does not affect the bottle cap 300 from closing the upper end of the bottle body 100.

[0044] Reference Figure 3 In a further embodiment of the present invention, a lifting head 251 having a contour larger than that of the lifting column 250 is provided at the upper end of the lifting column 250, thereby preventing the lifting column 250 from slipping when being lifted by pinching the lifting column 250.

[0045] Reference Figure 3 In a further embodiment of the present invention, a threaded section 150 is provided on the outer peripheral wall of the upper end of the bottle body 100, and the bottle cap 300 is threadedly connected to the threaded section 150, thereby facilitating the installation and removal of the bottle cap 300.

[0046] Reference Figure 3 In a further embodiment of the present invention, the bottom wall of the threaded section 150 is provided with an outwardly protruding bead 160, which is used to abut against the bottom of the bottle cap 300, thereby playing a limiting role when the bottle cap 300 closes the upper end of the bottle body 100, and the bottle cap 300 is tightly abutted against the bead 160, which also improves the sealing effect. Of course, a circle of sealing gasket can be attached to the bead 160 to further improve the sealing performance.

[0047] Reference Figure 2 In a further embodiment of the present invention, an upwardly protruding tapered portion 140 is provided at the center of the bottom of the bottle 100, thereby reducing the amount of liquid used in the bottle 100. Furthermore, when the bottle 100 is placed, a matching base can be provided, and the base has a positioning structure that fits into the tapered portion 140, thereby achieving positioning and limiting during storage. Of course, in other embodiments, the bottom of the bottle 100 can also be flat.

[0048] Reference Figure 1 and Figure 3In a further embodiment of the present invention, a recessed positioning groove 310 is provided at the upper end of the bottle cap 300. The positioning groove 310 is used to receive the bottom of the bottle body 100, thereby facilitating position limiting when stacking and ensuring stability. Specifically, when the bottom of the bottle body 100 is inserted into the positioning groove 310, the bottom of the bottle body 100 and the positioning groove 310 form an interference fit, thereby improving the connection stability when the two are stacked.

[0049] It is understood that the bottle body 100 is typically made of a transparent plastic material to facilitate viewing of the contents, such as polypropylene (PP). Polypropylene is a high-performance thermoplastic with advantages such as low specific gravity, non-toxicity, ease of processing, and resistance to impact and flexing. Medical-grade PP has high transparency and good barrier properties.

[0050] Reference Figure 2 and Figure 4 In some embodiments of the present invention, the bottom of the inner bottle 200 is arranged to be gathered downward toward the middle, so that when the inner bottle 200 is lifted upward, the pathological tissue will gather toward the center of the bottom of the inner bottle 200, thereby facilitating the removal of the pathological tissue.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
