Description

Technical Field

[0001] The utility model relates to the technical field of antibody adding devices, in particular to a portable antibody adding device. Background Art

[0002] A portable antibody addition device is a device used to quickly and conveniently add antibodies to samples or reactions. It is typically used in laboratory research, diagnostic testing, or treatment processes, improving work efficiency and reducing operational steps.

[0003] For example, the patent publication number CN213000063 U describes a device suitable for adding antibodies to the production process of an immunoaffinity column. The solution described therein is as follows: through the combined use of accessories, a controller carrying a control panel can be assembled on the top of the air pump, and an air pipe carrying an inner tube can be assembled at the output end of the air pump. The air pipe has a porous nail with an inner groove, which can be assembled with the outer protrusion on the combination cap to allow the porous nail to pierce the sealing film on the nail hole. After removing the hole plug, the antibody in the antibody column is added to the production process of the immunoaffinity column, thereby avoiding the oxidation probability of the antibody during the transfer process before addition, having good sealing performance, and eliminating the disadvantages of cleaning the inside of the device when the adding device is not in direct contact with the antibody, thereby reducing the difficulty of work and ensuring the cleanliness of the antibody addition process.

[0004] In the above case, when adding antibodies that need to be protected from light, it is difficult to protect the antibodies from light, which may cause some antibodies to become inactivated, thereby affecting the accuracy of the experimental results. At the same time, the above case is not convenient to carry, and the antibody column is exposed to the outside when carried, which may cause it to break or accidentally injure the operator.

After the connecting block 501 moves, it drives the needle 401 to move up and down. When the needle 401 moves to the appropriate position, the card column 506 is aligned with the through slot 507, clamped into the storage block 200, and then clamped into the interior of the connecting block 501 to fix the position of the needle 401, which is convenient for extracting the antibody.

[0030] In one embodiment, Figure 2 and Figure 3 As shown, the protective assembly includes a light shield 601, which is movably connected to the bottom of the fixed block 300. Sliding grooves 602 are provided on both sides of the top of the light shield 601. A clamping block 603 is slidably connected to the inside of the sliding groove 602. A spring 604 is installed between the clamping block 603 and the sliding groove 602. A clamping groove 605 corresponding to the position of the clamping block 603 is provided at the bottom of the fixed block 300. By putting the light shield 601 on the column body 1 from bottom to top 00 outside, and then press the clamping block 603 toward the column body 100 at the same time. The clamping block 603 squeezes the spring 604 to move closer to the column body 100. At this time, the light shield 601 is close to the bottom of the fixing block 300, and the clamping block 603 is aligned with the clamping groove 605. Then the clamping block 603 is released. At this time, the spring 604 is no longer squeezed, and the spring 604 drives the clamping block 603 to move toward the light shield 601. The clamping block 603 and the clamping groove 605 abut against each other, and the light shield 601 can be fixed.

[0031] In one embodiment, Figure 2 As shown, a cover 701 is movably connected to the bottom of the storage block 200; the cover 701 can prevent the needle 401 from accidentally injuring the operator when carrying the adding device.

[0032] In one embodiment, Figure 1 and Figure 2 As shown, a pressing plate 702 is installed on the top of the connecting rod 404; the pressing plate 702 can be used to press the connecting rod 404 downward and pull it upward.

[0033] In one embodiment, Figure 3 As shown, the top of the clamping block 603 is hook-shaped, which is convenient for cooperating with and abutting against the clamping slot 605 .

[0034] In one embodiment, Figure 1 and Figure 2 As shown, the light shield 601 is sleeved on the outer wall of the column body 100; the light shield 601 can be used when some light-shielding antibodies need to be added, and can effectively avoid direct light.

[0035] The above embodiment discloses a convenient antibody adding device, wherein, first, it is determined whether the antibody needs to be protected from light.

At this time, the light shield 601 is close to the bottom of the fixing block 300, and the clamping block 603 is aligned with the clamping groove 605. Then the clamping block 603 is released. At this time, the spring 604 is no longer squeezed, and the spring 604 drives the clamping block 603 to move toward the light shield 601. The clamping block 603 and the clamping groove 605 abut against each other, and the light shield 601 can be fixed. Then the card column 506 is pulled out of the storage block 200, and then the sliding block 505 is moved up and down. The sliding block 505 drives the connecting rod 504 and the connecting block 501 to move, and moves up and down with the assistance of the slider 502 and the slide groove 503 to prevent the connecting block 501 from deviating from its position during the displacement process.
