Detailed Implementation

[0019] 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.

[0020] like Figures 1 to 3 As shown in the figure, this embodiment specifically discloses a tumor exfoliated cell adsorption and collection device, including a placement bucket 1. The placement bucket 1 includes a bucket body 11 and a bucket bottom plate 12. The lower part of the inside of the bucket body 11 is provided with an internal thread. The bucket bottom plate 12 is connected to the bucket body 11 by the thread. The bottom surface of the bucket bottom plate 12 can contact the negative pressure drainage tank 2 below. By rotating the bucket bottom plate 12, the bucket bottom plate 12 can be removed from the bucket body 11, which can facilitate the removal of the negative pressure drainage tank 2 from the bucket body 11 and can treat the accumulated fluid in the negative pressure drainage tank 2.

[0021] Both sides of the bottom surface of the bucket bottom plate 12 are provided with cross grooves 121, and cross seats 81 are inserted into the corresponding cross grooves 121. The bucket bottom plate 12 can be rotated by the handle 8. When the bucket bottom plate 12 comes into contact with the negative pressure drainage tank 2 below, it can support the negative pressure drainage tank 2. When the bucket bottom plate 12 moves out of the bucket body 11, it can be easily separated from the negative pressure drainage tank 2 above and the negative pressure drainage tank 2 below can be taken out of the bucket body 11.

[0022] The container 1 contains two negative pressure drainage tanks 2 placed vertically. The two negative pressure drainage tanks 2 are connected by a sealing ring 3. A valve 4 is installed at the lower end of the upper negative pressure drainage tank 2, and a drainage pipe 5 is installed above the upper negative pressure drainage tank 2. A can lid 6 is installed at the upper end of the upper negative pressure drainage tank 2. The can lid 6 includes a lid body 61 and a bottleneck 62. The bottleneck 62 is connected to the top surface of the upper negative pressure drainage tank 2. The upper end of the bottleneck 62 passes through the container body 11 and is fixedly connected to the container body 11. The upper end of the bottleneck 62 has an external thread. The bottleneck 62 is connected to the lid body 61 by the thread. The lid body 61 is movably connected to the filter assembly 7. Opening the lid body 61 makes it easy to remove the filter assembly 7 from the upper negative pressure drainage tank 2, which facilitates cell processing.

[0023] The lower end of the drainage tube 5 passes through the can lid 6 and communicates with the inside of the negative pressure drainage tank 2. A filter assembly 7 is installed inside the negative pressure drainage tank 2. The upper end of the filter assembly 7 cooperates with the can lid 6. The filter assembly 7 includes a bag filter screen 71, a spring 72, and a connecting rod 73. Connecting rods 73 are hinged to both sides of the upper end of the filter screen 71. A limiting rod 74 is fixedly installed on one side of the connecting rod 73. Limiting grooves 75 are opened on both sides inside the lid 61. The limiting rod 74 is inserted into the corresponding limiting groove 75. The upper end of the spring 72 is fixedly connected to the limiting rod 74, and the lower end of the spring 72 is... The filter screen 71 is fixedly connected and can be placed into the negative pressure drainage tank 2 above. Pressing the limiting rod 74 brings the two limiting rods 74 closer together, allowing the limiting rod 74 to move out of the limiting groove 75, thereby removing the bag filter screen 71 from the cover 61. The bag filter screen 71 is then placed into the negative pressure drainage tank 2 above, with the upper end of the bag filter screen 71 engaging with the cover 61. Under the action of the spring 72, the limiting rod 74 is pushed into the corresponding limiting groove 75, thus fixing the bag filter screen 71.

[0024] A handle 8 is movably mounted on the top surface of the container 1. The lower end of the handle 8 mates with the bottom surface of the container 1. The handle 8 is an inverted U-shaped frame. Cross seats 81 are fixedly installed on both sides below the handle 8. Connecting sleeves 82 are fixedly installed on both sides of the top surface of the container 11. A slot 83 is opened on one side of the connecting sleeve 82. The cross seat 81 is inserted into the corresponding connecting sleeve 82. A protrusion 84 is fixedly installed on one side of the cross seat 81. The protrusion 84 is inserted into the corresponding slot 83. The device can be lifted and moved by the handle 8. The handle 8 can be used as a handle by the movable connection between the handle 8 and the container 11. It is a multi-purpose and practical device.

[0025] Working principle:

[0026] In use, the drainage tube 5 and the negative pressure drainage tank 2 work together to achieve negative pressure drainage. The accumulated fluid enters the negative pressure drainage tank 2 through the drainage tube 5. The cells are adsorbed through the bag filter 71, and the accumulated fluid flows into the lower negative pressure drainage tank 2. The cross seat 81 is inserted into the corresponding cross groove 121. The bottom plate 12 can be rotated by the handle 8. When the bottom plate 12 contacts the lower negative pressure drainage tank 2, it can support the negative pressure drainage tank 2. After the bottom plate 12 moves out of the tank body 11, it is easy to separate the lower negative pressure drainage tank 2 from the upper negative pressure drainage tank 2 and remove the lower negative pressure drainage tank 2 from the tank body 11, which facilitates the removal of the lower negative pressure drainage tank 2. The lower negative pressure drainage tank 2 can be removed from the barrel 11 to treat the accumulated liquid in the negative pressure drainage tank 2. Opening the cover 61 makes it easy to remove the filter assembly 7 from the upper negative pressure drainage tank 2 for cell treatment. Pressing the limiting rod 74 brings the two limiting rods 74 closer together, allowing the limiting rod 74 to move out of the limiting groove 75, thus removing the bag filter 71 from the cover 61. The bag filter 71 is then placed into the upper negative pressure drainage tank 2, with the upper end of the bag filter 71 engaging with the cover 61. Under the action of the spring 72, the limiting rod 74 is pushed into the corresponding limiting groove 75, thus fixing the bag filter 71.
