Abstract
Description
Technical Field
[0001] This utility model relates to the field of specimen collection technology, specifically a tumor specimen collector. Background Technology
[0002] Existing tumor specimen collection technology involves placing tumor tissue into a separator and adding a preservation solution to the shell, which increases the contact area between the preservation solution and the tumor tissue, thus facilitating long-term preservation of the tumor tissue. However, when the tumor specimen is placed in the separator, the separator can isolate the preservation solution. Therefore, the permeability of the filter cloth is utilized to allow formalin fixative to impregnate the filter cloth and preserve the tumor specimen. Furthermore, when dealing with multiple tumor specimens, the collector is used to separate the preservation positions of the tumor specimens and to separate the fluid carried by the tumor specimens, avoiding difficulties in subsequent sampling of the tumor specimens. Therefore, a tumor specimen collector that solves the above problems is needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 A tumor specimen collector includes: a collection base 1, an outlet pipe 2 fixedly connected to the outer wall of the collection base 1, a cap 3 sleeved on the outer wall of the outlet pipe 2, a liquid chamber 4 in the inner cavity of the collection base 1, an inner groove 5 formed in the inner wall of the collection base 1, an overlapping ring 6 placed on the top of the collection base 1, a connecting joint 7 on the outer wall of the overlapping ring 6, an outer ring groove 8 on the outer wall of the overlapping ring 6, a separation plate 9 on the inner wall of the overlapping ring 6, a placement ring 10 on the outer wall of the separation plate 9, a bottom support wall 11 formed in the inner wall of the placement ring 10, and a placement ring 10 sleeved on the inner wall of the placement ring 10. The inner wall of the storage tank 12 is connected to a filter cloth 13. The outer wall of the separation disc 9 is fixedly connected to an extension cylinder 14. The top of the bottom collection tank 1 is placed on the top of the collection tank 1. The outer wall of the top collection tank 15 is fixedly provided with a discharge port 16. The inner wall of the top collection tank 15 is fitted with an input cylinder 17. The top of the input cylinder 17 is placed with a sealing cap 18. The outer wall of the top collection tank 15 is fixedly connected to a threaded wall 19. The inner wall of the threaded wall 19 is fitted with an observation lens 20. The inner wall of the observation lens 20 is equipped with a magnifying lens 21. The top of the observation lens 20 is equipped with a rubber soft ring 22.
[0023] The inner cavity of the collecting tank 1 is connected to the inner cavity of the liquid outlet pipe 2, and the inner wall of the button cover 3 is movably sleeved with the outer wall of the liquid outlet pipe 2. By connecting the inner cavity of the collecting tank 1 and the inner cavity of the liquid outlet pipe 2, when the inner cavity of the collecting tank 1 is filled with liquid, the liquid is directed to the inner cavity of the liquid outlet pipe 2, and when the button cover 3 is removed from the outer wall of the liquid outlet pipe 2, the liquid flows out of the device from the liquid outlet pipe 2.
[0024] Among them, there are two connectors 7, and the two connectors 7 are symmetrically arranged on both sides of the overlapping ring 6. Through the two connectors 7 on the device, the overlapping ring 6 on the device can be connected with the inner groove 5 by the connectors 7 on both sides, so that the overlapping ring 6 on the device can be installed on the inner wall of the collecting bottom tank 1.
[0025] The inner wall of the inner groove 5 has the same diameter as the outer wall of the connector 7, and the connector 7 is inserted into the inner cavity of the inner groove 5. Because the inner wall of the inner groove 5 and the outer wall of the connector 7 have the same diameter, when the overlapping ring 6 of the device is inserted into the inner cavity of the inner groove 5 by the connector 7, the overlapping ring 6 of the device rotates with the rotation of the collecting bottom tank 1 due to the docking relationship between the inner groove 5 and the connector 7, and the overlapping ring 6 remains unchanged when the collecting bottom tank 1 remains unchanged.
[0026] The outer ring groove 8 is circumferentially matched with the inner wall circumference of the collecting top tank 15, and the collecting top tank 15 covers the outer wall of the overlapping ring 6. By matching the outer ring groove 8 with the inner wall circumference of the collecting top tank 15, the collecting top tank 15 is fitted onto the outer wall of the outer ring groove 8, and the collecting top tank 15 itself is manually rotatable. Thus, when the collecting top tank 15 rotates, it rotates in a circle around the input cylinder 17 as the center point.
[0027] The device has four placement rings 10 and four bottom support walls 11, which are evenly arranged on the outer wall of the separation plate 9. The four placement rings 10 and bottom support walls 11 on the device make the placement rings 10 evenly opened on the outer wall of the separation plate 9, and each placement ring 10 has a bottom support wall 11 in its inner cavity, so that the four bottom support walls 11 support the four storage tanks 12.
[0028] The discharge port 16 is located directly above the storage tank 12, and the center point of the filter cloth 13 is in a downward position. By setting the discharge port 16 directly above the storage tank 12, the filter cloth 13 in the device naturally has a downward position at its center point, and the tumor specimen is delivered downward through the discharge port 16, so that the surface of the filter cloth 13 is loaded with the tumor specimen.
[0029] The outer wall of the observation mirror 20 is provided with external threads, and the observation mirror 20 is threadedly connected to the threaded wall 19 through the external threads. Because the outer wall of the observation mirror 20 is provided with external threads, when the observation mirror 20 is installed in the inner cavity of the threaded wall 19, the observation mirror 20 can be rotated under manual control. Furthermore, by utilizing the threaded connection between the observation mirror 20 and the threaded wall 19, the observation mirror 20 can change its height along the inner wall of the threaded wall 19.
[0030] The working principle is as follows: First, through the coordinated use of the discharge port 16, the liquid outlet pipe 2, the storage tank 12, and the filter cloth 13, tumor specimens are allowed to enter the inner cavity of the storage tank 12 from the discharge port 16. The filter cloth 13 loads the tumor specimens and separates the liquid carried by the tumor specimens, with the liquid entering the inner cavity of the liquid chamber 4. This allows multiple tumor specimens to enter the inner cavities of multiple storage tanks 12 for separation of the tumor specimens from the liquid. Then, the specimens are observed through the observation mirror 20 on the device... The magnifying lens 21, along with the storage container 12, filter cloth 13, and input tube 17, work together to preserve the tumor specimen loaded in the inner cavity of the storage container 12 by immersing the filter cloth 13 in the formalin fixation solution added at the input tube 17. The observation lens 20 moves up and down within the inner cavity of the threaded wall 19, adjusting the height of the magnifying lens 21. This allows the device to preserve the sample while simultaneously allowing observation of the tumor specimen using the magnifying lens 21.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
