[0002] In the diagnosis of ophthalmic diseases (such as vitreoretinal diseases and intraocular tumors), the detection and analysis of exfoliated cells in the vitreous humor are crucial. These exfoliated cells may carry morphological and molecular information related to the disease, and their extraction efficiency and integrity directly affect diagnostic accuracy. Therefore, how to efficiently and minimally invasively extract exfoliated cells from vitreous humor specimens has become an important technical requirement in the field of ophthalmic clinical testing. The vitreous humor is a transparent, viscous liquid similar to egg white; after surgical removal, the volume of the vitreous humor specimen used for cell extraction is only about 1 ml.

[0003] Existing evaporation devices for extracting exfoliated cells from the vitreous humor are not convenient for restricting the position of the container during the evaporation process, which affects the evaporation experiment. Furthermore, existing evaporation devices for extracting exfoliated cells from the vitreous humor are not convenient for providing a relatively sealed space, which can easily lead to external contamination of the exfoliated cells from the vitreous humor. The present invention provides an evaporation device for extracting exfoliated cells from the vitreous humor that solves the above problems. Utility Model Content

A T-shaped slider 8 is installed at the bottom of the threaded ring block 7. A support rod 9 is installed at the top of the threaded ring block 7. An arc-shaped limiting plate 10 is installed at the end of the support rod 9. A rubber pad 11 is installed on the inner surface of the rectangular frame 4. A cylindrical heat-conducting seat 12 is installed on the top of the rectangular frame 4. A constant temperature heater 13 is installed inside the cylindrical heat-conducting seat 12. An exhaust pipe 14 is installed on the top of the protective cover 2. An exhaust one-way valve 15 is installed inside the exhaust pipe 14. A limit spring 16 is installed inside the regulating box 3. A limit block 17 is installed at one end of the limit spring 16. A push block 18 is installed on the top of the limit block 17. A cross slider 19 is installed at the bottom of the limit block 17. A positioning block 20 is installed on the outer surface of the protective cover 2.

[0017] Specifically, the cooperation between the T-shaped slider 8 and the T-shaped groove facilitates positioning and guidance, improving the stability of the movement of the threaded ring block 7 and the arc-shaped limiting plate 10.

[0018] Please refer to Figure 2 to Figure 3The inner bottom wall of the rectangular frame 4 is provided with a T-shaped groove with the vertical direction as the depth direction and the horizontal direction as the length direction. The end of the T-shaped slider 8 is located inside the T-shaped groove, and the T-shaped slider 8 can slide along the length direction of the T-shaped groove.

[0019] Specifically, the transmission cooperation between the threaded rod 6 and the threaded ring block 7 facilitates the movement of the arc-shaped limiting plate 10, thus facilitating the restriction of the container's position.

[0020] Please refer to Figure 2 to Figure 3 The end of the threaded rod 6 away from the dual-axis motor 5 is rotatably connected to the inner wall of the rectangular frame 4 through a bearing, and the position of the arc-shaped limiting plate 10 is higher than the position of the cylindrical heat-conducting seat 12.

[0021] Specifically, the protective shield 2 serves as an external barrier, preventing external environmental contamination of cells detached from the vitreous humor of the eye inside the container.

[0022] Please see Figures 1 to 5 The protective cover 2 is fitted onto the outside of the rectangular frame 4 and the cylindrical heat-conducting base 12, and the position of the regulating box 3 is located outside the protective cover 2.

[0023] Specifically, the annular groove serves to position the protective cover 2, and the sealing ring 21 improves the sealing performance of the connection.

[0024] Please refer to Figure 1 to Figure 5 The top of the base plate 1 has an annular groove with the vertical direction as the depth direction. The end of the protective cover 2 is inserted into the inside of the annular groove. The bottom of the protective cover 2 is provided with a sealing ring 21, which abuts against the inner wall of the annular groove.

[0025] Specifically, the positioning block 20 and the interior of the positioning groove serve to position and install the protective cover 2. The setting of the limiting block 17 facilitates the restriction of the position of the positioning block 20 and improves the stability of the installation of the protective cover 2. The setting of the cross slider 19 improves the stability of the movement of the limiting block 17 and facilitates the limiting block 17 to better restrict the position of the positioning block 20.

[0026] Please see Figures 1 to 5 The top of the regulating box 3 is provided with a positioning groove with the vertical direction as the depth direction. The end of the positioning block 20 is inserted into the inside of the positioning groove. A limit groove is provided on one side of the positioning block 20. The end of the limit block 17 away from the limit spring 16 is inserted into the inside of the limit groove. A cross slide groove is provided inside the regulating box 3. The end of the cross slider 19 is located inside the cross slide groove. The cross slider 19 can slide along the length direction of the cross slide groove.

[0027] In use, open the protective cover 2, push the push block 18, causing the limiting block 17 to move the cross slider 19, causing the limiting spring 16 to contract under force, so that the cross slider 19 acts as a guide inside the cross groove, causing the end of the limiting block 17 to leave the limiting groove. Then, move the protective cover 2 upward, causing the positioning block 20 to leave the positioning groove, and the bottom end of the protective cover 2 to leave the annular groove. When heating and evaporating exfoliated cells from the vitreous humor, place the container containing the exfoliated cells from the vitreous humor above the cylindrical heat-conducting seat 12. When restricting the position of the container, the dual-axis motor 5 drives the threaded rod 6 to rotate. The threaded rod 6 is connected to the threaded ring block 7. The T-shaped slider 8 acts as a guide inside the T-shaped groove, causing the threaded ring block 7 to move the T-shaped slider 8, the support rod 9, and the arc-shaped limiting plate 10, so that the two arc-shaped limiting plates 10 move synchronously to clamp the container. The rubber pad 11 is installed to prevent damage to the container during clamping and to facilitate limiting the container's position. Then, the protective cover 2 is moved so that its bottom end is placed inside the annular groove. The sealing ring 21 improves the sealing at the connection point, allowing the end of the positioning block 20 to enter the positioning groove. When the bottom of the positioning block 20 reaches the end of the positioning groove, the limiting groove aligns with the limiting block 17. The pull plate is released, and the elastic tension of the limiting spring 16 allows the end of the limiting block 17 to insert into the limiting groove, facilitating the restriction of the positioning block 20's position and improving the stability of the protective cover 2. The constant temperature heater 13 heats the container, transferring heat through the cylindrical heat-conducting seat 12 to evaporate the exfoliated cells from the vitreous humor inside the container. Exhaust is achieved through the exhaust pipe 14 and the exhaust check valve 15, preventing excessive pressure inside the protective cover 2 and improving practicality.
