Description

Technical Field

[0001] This utility model relates to the field of cell screening tube technology, specifically a cell screening tube. Background Technology

[0002] With the continuous improvement of people's living standards, health problems caused by various diseases are receiving increasing attention. For example, human umbilical cord mesenchymal stem cells have great potential medical value in the treatment of diabetes and cardiovascular diseases. Typically, when studying stem cell differentiation, cell clusters are obtained by culturing and culturing tissue fragments. However, the cell clusters obtained from the filtered cell solution are of varying sizes, and contamination can easily occur during the filtration process, affecting stem cell differentiation research. Therefore, a separation and screening device is needed that can reduce human contamination and separate cell clusters of uniform size for subsequent comparative studies.

[0003] In the prior art, such as the cell screening tube proposed in announcement number CN220597467U, this technical solution discloses a cell screening tube, including a screening tube body, a liquid inlet provided at the top of the screening tube body, a separation cap provided at one end of the screening tube body, and a liquid pressing device provided at the other end. During screening, the liquid pressing device presses the cell mixture towards the separation cap. The fixed cap and the screening cap are rotatably connected. The screening cap is fixedly provided with a flange at one end near the screening tube body. The side wall of the screening cap is evenly provided with a plurality of screening holes along the circumference. The screening holes are fixed with screening membranes. The side wall of the fixed cap is provided with a liquid outlet hole that cooperates with the screening holes. The cell mixture is pressed towards the separation end by the liquid pressing device. Different filter membranes are provided in different screening holes. Therefore, the screening cap can be rotated accordingly to make the screening holes align with the liquid outlet hole. This allows for convenient and targeted extraction of the cell mixture. That is, different types of extraction can be completed through a single liquid outlet hole.

[0004] However, in the existing cell screening tube, the fixing cover is fixed to one side of the screening tube body by a threaded connection. This not only makes the disassembly and assembly of the device more troublesome, but also the fixing cover may loosen after long-term use, thus affecting the sealing performance of the device. Furthermore, the device cannot fix the screening cover, which may cause the screening cover to rotate during the operation of the device, thus affecting the normal operation of the device.

[0005] To address the aforementioned issues, this application proposes a cell screening tube. Utility Model Content

[0006] This utility model aims to provide a cell screening cylinder, mainly to solve the problem that the fixed cover on the existing cell screening cylinder is fixed to one side of the screening cylinder body by a threaded connection. This not only makes the disassembly and assembly of the device more troublesome, but also the fixed cover may loosen after long-term use. Furthermore, the device cannot fix the screening cover, which may cause the screening cover to rotate during the operation of the device, thereby affecting the normal operation of the device.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A cell screening cylinder includes a cylinder body, a connecting cylinder, a screening cover, and multiple screens of different specifications disposed on the screening cover. The outer wall of the cylinder body has multiple first T-shaped grooves, and a first T-shaped block is slidably connected inside each of the first T-shaped grooves. A symmetrical spring is fixedly connected to one side of the inner wall of the first T-shaped groove, and the other end of the spring is fixedly connected to the first T-shaped block. One side of the first T-shaped block extends out of the cylinder body and is fixedly connected to an L-shaped locking block. Multiple connecting blocks are hinged to one side of the connecting cylinder, and each connecting block has a through groove that matches the L-shaped locking block. A limiting component for fixing the screening cover is disposed on the side of the connecting cylinder away from the connecting blocks.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When using this cell screening tube, the connecting tube is installed at one end of the tube body. Then, multiple connecting blocks on one side of the connecting tube are rotated so that multiple L-shaped locking blocks on the tube body pass through the through slots on the connecting blocks. The L-shaped locking blocks will engage with the connecting blocks under the action of the spring inside the first T-shaped groove, thereby fixing the connecting tube at one end of the tube body. Then, the screening cover is rotated so that the corresponding screen is aligned with the liquid outlet on the connecting tube. The screening cover is fixed by the limiting component, and the device can then operate normally. (The cell mixture to be screened is added into the tube body through the liquid inlet. By rotating the push handle, the piston pushes the cell mixture towards the separation end and the screening end, so that the cell mixture can be extracted in a targeted manner.) The part in parentheses is the prior art, which is not described in detail in this application document.

[0011] 2. Beneficial effects: After the connecting cylinder is installed at one end of the cylinder body, rotating multiple connecting blocks allows the L-shaped locking block to pass through the through groove, thus fixing the connecting cylinder at one end of the cylinder body. This not only makes the assembly and disassembly of the connecting cylinder more convenient, but also makes the connection between the connecting cylinder and the cylinder body more secure. After rotating the screening cover to align the corresponding screen with the liquid discharge hole on the connecting cylinder, the screening cover is fixed by the limiting component. This effectively prevents the screening cover from rotating during the operation of the device, thereby further improving the stability of the device during operation.

[0012] Preferably, the limiting component includes a movable block slidably connected to the side of the connecting cylinder away from the connecting block. A second T-shaped block is fixedly connected to one side of the movable block. A second T-shaped groove matching the second T-shaped block is opened on the connecting cylinder. A plurality of U-shaped blocks matching the movable block are fixedly connected to one side of the screening cover. The U-shaped blocks are matched with the screens on the screening cover. After the connecting cylinder is fixed to the cylinder body, the movable block is slid upward, and then the screening cover is rotated so that the corresponding screen is aligned with the liquid outlet on the connecting cylinder. At this time, the movable block is released. The movable block will move downward under the action of gravity and engage with the corresponding U-shaped block on the screening cover, which can play a good role in fixing the screening cover. This can effectively prevent the screening cover from rotating during the operation of the device, thereby further improving the stability of the device during operation.

[0013] Preferably, a positioning block is fixedly connected to the inner wall of the connecting cylinder, and a positioning groove matching the positioning block is opened on the outer wall of the cylinder. When installing the connecting cylinder, the positioning block inside the connecting cylinder needs to be aligned with the positioning groove on the outer wall of the cylinder. This can play a better positioning role for the connecting cylinder, thereby making the installation of the connecting cylinder more convenient.

[0014] Preferably, magnets are fixedly connected to the top and bottom of the second T-shaped block, and iron plates that attract the magnets are fixedly connected to the top and bottom of the inner wall of the second T-shaped groove. By sliding the moving block upward, the magnet at the top of the second T-shaped block attracts the iron plate at the top of the inner wall of the second T-shaped groove, and the screening cover can be rotated to align the corresponding screen with the liquid outlet on the connecting cylinder. Then, by sliding the moving block downward, the magnet at the bottom of the second T-shaped block attracts the iron plate at the bottom of the inner wall of the second T-shaped groove, thus fixing the screening cover. This effectively prevents the moving block from detaching from the U-shaped block, thereby further improving the stability of the device during operation.

[0015] Preferably, a label box is fixedly connected to one side of the U-shaped block on the screening cover, and the label box is made of acrylic sheet material. The label box on the screening cover can hold a label, which is used to mark the specifications of the screen, making it more convenient for the staff to switch screens.

[0016] Preferably, a sealing ring is fixedly connected to the side of the cylinder near the connecting cylinder, and the sealing ring is made of rubber material. After the connecting cylinder is installed at one end of the cylinder, the sealing ring on one side of the cylinder will press against the connecting cylinder, which can make the sealing at the connection between the cylinder and the connecting cylinder better.

[0017] Preferably, all corners of the inner wall of the U-shaped block at the opening are chamfered. By setting all corners of the inner wall of the U-shaped block at the opening as chamfered, it is easier to insert the moving block into the U-shaped block, thus making the device easier to use.

[0024] 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.

[0025] Please see Figure 1-5A cell screening cylinder includes a cylinder body 1, a connecting cylinder 2, a screening cover 3, and multiple screens 4 of different specifications disposed on the screening cover 3. A positioning block 15 is fixedly connected to the inner wall of the connecting cylinder 2. A positioning groove 16 matching the positioning block 15 is formed on the outer wall of the cylinder body 1. When installing the connecting cylinder 2, the positioning block 15 inside the connecting cylinder 2 needs to be aligned with the positioning groove 16 on the outer wall of the cylinder body 1. This provides a good positioning effect for the connecting cylinder 2. Multiple first T-shaped grooves 5 are formed on the outer wall of the cylinder body 1. A first T-shaped block 6 is slidably connected inside each of the first T-shaped grooves 5. A symmetrical spring 7 is fixedly connected to one side of the inner wall of the first T-shaped groove 5, and the other end of the spring 7 is fixedly connected to the first T-shaped block 6. One side of the first T-shaped block 6 extends out of the cylinder body 1 and is fixedly connected to an L-shaped locking block 8. Multiple connecting blocks 9 are hinged to one side of the connecting cylinder 2. Each of the 9 has a through groove 10 that matches the L-shaped locking block 8. The connecting cylinder 2 is installed at one end of the cylinder body 1. Then, the multiple connecting blocks 9 on one side of the connecting cylinder 2 are rotated so that the multiple L-shaped locking blocks 8 on the cylinder body 1 pass through the through groove 10 on the connecting block 9. The L-shaped locking blocks 8 will engage with the connecting block 9 under the action of the spring 7 inside the first T-shaped groove 5, thus fixing the connecting cylinder 2 to one end of the cylinder body 1. A sealing ring 20 is fixedly connected to the side of the cylinder body 1 near the connecting cylinder 2. The sealing ring 20 is made of rubber material, which makes the sealing at the connection between the cylinder body 1 and the connecting cylinder 2 better. A limiting component for fixing the screening cover 3 is provided on the side of the connecting cylinder 2 away from the connecting block 9. The screening cover 3 is rotated so that the corresponding screen 4 is aligned with the liquid outlet on the connecting cylinder 2. The screening cover 3 is fixed by the limiting component, and the device can then operate normally.

[0026] like Figure 3 and Figure 4As shown, the limiting assembly includes a movable block 11 slidably connected to the side of the connecting cylinder 2 away from the connecting block 9. A second T-shaped block 12 is fixedly connected to one side of the movable block 11. A second T-shaped groove 13 matching the second T-shaped block 12 is opened on the connecting cylinder 2. Magnets 17 are fixedly connected to the top and bottom of the second T-shaped block 12. Iron pieces 18 attracted to the magnets 17 are fixedly connected to the top and bottom of the inner wall of the second T-shaped groove 13. Multiple U-shaped blocks 14 matching the movable block 11 are fixedly connected to one side of the screening cover 3. The U-shaped blocks 14 are matched with the screen 4 on the screening cover 3. The corners of the inner wall of the U-shaped blocks 14 at the opening are all chamfered. Label boxes 19 are fixedly connected to one side of the U-shaped block 14. The label boxes 19 are made of acrylic sheet material. After the connecting cylinder 2 is fixed to the cylinder 1, the moving block 11 is slid upward so that the magnet 17 at the top of the second T-shaped block 12 attracts the iron sheet 18 at the top of the inner wall of the second T-shaped groove 13. Then, the screening cover 3 is rotated so that the corresponding screen 4 is aligned with the liquid outlet on the connecting cylinder 2. Then, the moving block 11 is slid downward so that the magnet 17 at the bottom of the second T-shaped block 12 attracts the iron sheet 18 at the bottom of the inner wall of the second T-shaped groove 13. The screening cover 3 can be fixed in this way, which can effectively prevent the moving block 11 from detaching from the U-shaped block 14, thereby further improving the stability of the device during operation.

[0027] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0028] When using this cell screening tube, the connecting tube 2 is installed at one end of the tube body 1. Then, the multiple connecting blocks 9 on one side of the connecting tube 2 are rotated so that the multiple L-shaped locking blocks 8 on the tube body 1 pass through the through slots 10 on the connecting blocks 9. The L-shaped locking blocks 8 will engage with the connecting blocks 9 under the action of the spring 7 inside the first T-shaped groove 5, thereby fixing the connecting tube 2 to one end of the tube body 1. Then, the moving block 11 is slid upward so that the magnet 17 on the top of the second T-shaped block 12 attracts the iron piece 18 on the top of the inner wall of the second T-shaped groove 13. Then, the screening cover 3 is rotated so that the corresponding... The screen 4 is aligned with the liquid outlet on the connecting cylinder 2. Then, the moving block 11 is slid down so that the magnet 17 at the bottom of the second T-shaped block 12 attracts the iron piece 18 at the bottom of the inner wall of the second T-shaped groove 13, thus fixing the screening cover 3. The device can then operate normally. (The cell mixture to be screened is added into the cylinder through the liquid inlet. By rotating the push handle, the piston pushes the cell mixture towards the separation end screening end, thus allowing for targeted extraction of the cell mixture.) The part in parentheses is prior art, which is not described in detail in this application.
