Description

Technical Field

[0001] This utility model relates to the field of biosafety cabinet technology, and more specifically, to a biosafety cabinet for cell detection. Background Technology

[0002] Biosafety cabinets are designed to protect the operator, the laboratory environment, and the experimental materials from exposure to infectious aerosols and splashes that may be generated during the handling of infectious experimental materials such as primary cultures, bacterial and viral strains, and diagnostic specimens.

[0003] Existing biosafety cabinets generally use wiping, but this may expand the contaminated area and turn the items being wiped with liquid into secondary contaminants, increasing processing costs. At the same time, the wiping effect is not ideal, it is slow and inconvenient to operate.

[0004] A search revealed a Chinese patent, CN216125653U, which discloses a biosafety cabinet for cell detection. This invention utilizes a negative pressure collection mechanism. During experiments, if liquid splashes or leaks occur in the cleanroom, creating a contaminated surface, the operator can move the handheld suction head of the negative pressure collection mechanism towards the contaminated surface and activate the foot pump. This generates airflow within the negative pressure collection mechanism, which is controlled by two one-way valves to direct airflow into the handheld suction head and out through the waste collection box, quickly absorbing the contaminated surface. This reduces manual cleaning, allows for unified treatment, minimizes secondary contamination, and is highly efficient and easy to operate.

[0005] However, in actual use, when too many samples are placed in the biosafety cabinet, the samples cannot be secured in time. After a long period of experimentation, when the experimenters get up and move around, they may accidentally bump into the biosafety cabinet, causing the sample containers in the cabinet to tilt or collide with each other, affecting the safety of the sample placement.

[0011] By adopting the above technical solution, three load-bearing plates can be expanded simultaneously, rapidly increasing the sample placement capacity inside the cleanroom. The sample container can also be clamped and limited to maintain stability during placement and retrieval, preventing tilting and collisions.

[0012] As a further description of the above technical solution: the support mechanism includes multiple protective shells and lockable casters.

Air from the main body 1 enters the clean working chamber 8 through the air inlet 6, is filtered by the filter 7, and further filtered by the filter plate 4. The ultraviolet lamp 5 continuously irradiates and sterilizes the inside of the clean working chamber 8. The support frame 2 supports the main body 1.

[0026] Reference Figure 1 , Figure 4 and Figure 5 As shown, the expansion mechanism includes two supports 9. One side of each support 9 is fixedly connected to the inside of the clean working chamber 8. Two pins 10 are slidably connected to the bottom of each support 9. A water pipe rotating rod 11 is rotatably connected to the inside of each support 9. Two guide rods 12 are fixedly connected to the outside of each rotating rod 11. A push plate 13 is hinged to one end of each guide rod 12. A load-bearing plate 14 is fixedly connected to the outside of each rotating rod 11. Multiple outer cylinders 15 and a placement frame 22 are fixedly connected to the outside of each load-bearing plate 14. A gasket 16 is fixedly connected to the inner wall of each outer cylinder 15. Multiple guide rods 17 are slidably connected to the inside of each outer cylinder 15. A spring 18 is sleeved on the outside of each gasket 16. A positioning plate 19 is fixedly connected to one side of each guide rod 17. A clamping plate 20 is hinged to the outside, and a spring 21 is fixedly connected to one side of the clamping plate 20. One side of the spring 21 is fixedly connected to one side of the positioning plate 19. The push plate 13 drives the three guide rods 12 to move, so that the guide rods 12 can drive the rotating rod 11 and the load-bearing plate 14 to rotate, so that the load-bearing plate 14 can be kept horizontal inside the clean working chamber 8. Then, the corresponding pins 10 are inserted into the lower guide rods 12 to keep the load-bearing plate 14 fixed. The corresponding guide rods 17 and spring 18 can clamp and limit the container placed inside the outer cylinder 15. At the same time, spring 21 can push the clamping plate 20 to fit the surface of the container.

[0027] Reference Figure 6 As shown, the support mechanism includes multiple protective shells 23 and locking casters 29. The upper surface of the protective shell 23 is fixedly connected to the bottom of the support frame 2, and the top of the multiple locking casters 29 is fixedly connected to the bottom of the support frame 2. Two guide blocks 24 are fixedly connected to the inner side of the protective shell 23. A lead screw 25 is slidably connected inside the protective shell 23. The outer side of the lead screw 25 is slidably connected to the inside of the support frame 2. Two grooves 26 are opened on the outer side of the lead screw 25. A threaded handle 27 is rotatably connected to the outer side of the protective shell 23. The inner side of the threaded handle 27 is threadedly connected to the outer side of the lead screw 25. A base 28 is fixedly connected to the bottom of the lead screw 25. Rotating the threaded handle 27 can perform threaded transmission on the lead screw 25 inside the support frame 2, so that the lead screw 25 can extend out from the inside of the lead screw 25 while being slidably guided by the guide blocks 24 and the grooves 26, so that the base 28 at the bottom of the lead screw 25 can provide stable support to the ground.

[0028] The working principle of this invention is as follows: When placing sample containers for cell detection, if there are many samples, first open the pull plate 3. A worker then inserts their hand into the cleanroom 8 to push one of the two push plates 13. This push plate 13 causes the corresponding guide rod 12 to rotate perpendicularly to the support 9. Then, the pin 10 at the bottom of the support 9, close to the guide rod 12, is inserted into the hole of the bottom guide rod 12. This causes the three rotating rods 11 to rotate the corresponding load-bearing plate 14 to a horizontal angle. Finally, the worker places the sample containers sequentially into the outer cylinder 15. During the process of the sample container entering the outer cylinder 15, the gasket 16 will cushion the bottom of the container. Then, when the container pushes the two positioning plates 19 inside the outer cylinder 15, they will push the guide rod 17 to separate the positions of the two positioning plates 19. After the container can enter the interior of the outer cylinder 15, the spring 18 on the outside of the multiple guide rods 17 will push the positioning plate 19 to clamp the container to the outside. Then, the corresponding spring 21 will push the clamping plate 20 to adjust the angle on the outside of the positioning plate 19, so that the two clamping plates 20 can better clamp and limit the container.

[0029] During the movement of the biosafety cabinet, the cabinet is moved with the assistance of the locking casters 29. After moving to the appropriate position, the corresponding threaded handle 27 is rotated to drive the lead screw 25. The lead screw 25 can extend vertically from the inside of the support frame 2 through the limiting of the slide groove 26 and the guide block 24, so that the base 28 can support the ground and complete the movement of the biosafety cabinet.
