Description

Technical Field

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

[0002] Cell culture is a core technology in biomedicine, drug development, and other fields, and accurate monitoring of cell number, viability, and concentration is crucial. Cell counters, as automated analytical devices, utilize optical imaging, image processing, or flow cytometry technology. Through non-invasive sampling or flow cytometry detection, combined with intelligent algorithmic analysis, they can quickly and accurately determine cell parameters. Compared to traditional manual counting, they are more efficient and provide more objective data, making them an indispensable tool in laboratories and industrial production.

[0003] The sample inlet of a traditional cell counter is directly exposed to the external environment, which makes it easy for dust in the air to enter the sample inlet and adhere to the lens, light source or sensor surface, obstructing the light path or interfering with the imaging quality, resulting in cell identification errors. For example, dead cells stained with trypan blue may be misidentified as live cells due to imaging interference, ultimately leading to a significant decrease in detection accuracy. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing a cell culture counter.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cell culture counter includes: a body, a shell, a flipping mechanism, and a flexible reset mechanism; The body has a sample inlet on its surface. The housing is mounted on the surface of the machine body and located below the sample inlet. Shafts are rotatably mounted on both sides inside the housing, and baffles are provided at the upper ends of the shafts. A flipping mechanism, located inside the housing, is used to open the baffle. An elastic reset mechanism is installed inside the housing and is used to drive the baffle to block the surface of the sample inlet. The flipping mechanism includes a gear mounted on the outer surface of the shaft, and a rack that runs through and slides inside the housing, with the rack meshing with the gear.

[0006] The beneficial effects of this utility model are as follows: by setting up a flipping mechanism, the baffle can be opened to expose the sample inlet, so that the cell counting plate can be easily inserted into the sample inlet for measurement. When the cell counting plate is pulled out from the sample inlet, the baffle can be driven to reset and cover the sample inlet again under the elastic force of the elastic reset mechanism. This can prevent dust in the air from entering the sample inlet when the machine is not in use, thus avoiding a decrease in detection accuracy.

[0007] Furthermore, a pressure block is installed at the end of the rack, and the surface of the pressure block is provided with anti-slip texture. This increases the contact area, reduces the pressure felt when pressing with the hand, and improves the anti-slip effect.

[0008] Furthermore, the elastic reset mechanism includes a fixed block installed inside the housing, with a spring connected to the surface of the fixed block, and the end of the spring connected to a rack. When the pressure block is released, the compressed spring releases its elastic force, allowing the baffle to once again cover the surface of the injection port.

[0009] Furthermore, a tube is mounted on the outer surface of the fixing block, and a guide rod is slidably mounted inside the tube. The end of the guide rod is connected to a rack, and a spring is sleeved on the outer surface of the tube and the guide rod. This guides the spring and prevents the tube from bending or deforming under gravity.

[0010] Furthermore, a piston body is installed at the end of the guide rod located inside the tube. The piston body has multiple through holes on its surface, and the inside of the tube is filled with oil. This reduces the flipping speed of the baffle, allowing it to slowly adhere to the surface of the injection port, avoiding rapid reset that could cause impact vibration and damage to the lens, light source, or sensor.

[0011] Furthermore, the end of the baffle is provided with a beveled portion; When the cell counting chamber is inserted into the sample inlet, the beveled part fits snugly against the chamber. This increases the clamping area of ​​the cell counting chamber, further improving the stability during the detection process.

[0012] Furthermore, a rubber layer is provided on the side of the baffle facing the machine body to further reduce the impact of an impact. Attached Figure Description

[0020] Example 1 Figure 1 This is a structural diagram of a cell culture counter provided in an embodiment of the present invention. Figure 2 This is a partial cross-sectional structural diagram of the present invention. (See attached diagram.) Figure 1 , Figure 2 As shown, the device includes: a body 1, a housing 2, a flipping mechanism 3, and an elastic reset mechanism 4; The body 1 has a sample inlet 101 on its surface; The housing 2 is mounted on the surface of the body 1 and is located below the sample inlet 101. Shafts 201 are rotatably mounted on both sides inside the housing 2, and baffles 202 are provided at the upper end of the shafts 201. The flipping mechanism 3 is installed inside the housing 2 and is used to open the baffle 202; Elastic reset mechanism 4 is disposed inside housing 2 and is used to drive baffle 202 to block the surface of sample inlet 101. The flipping mechanism 3 includes a gear 301 mounted on the outer surface of the shaft 201, and a rack 302 that runs through and slides inside the housing 2, meshing with the gear 301. A pressure block 303 is mounted on the end of the rack 302, and the surface of the pressure block 303 is provided with anti-slip texture.

[0021] In use, the operator pushes the two pressure blocks 303 inward. Utilizing the meshing relationship between the rack 302 and the gear 301, the two shafts 201 rotate simultaneously, opening the baffles 202. The operator can then insert the cell counting plate into the sample inlet 101 for measurement. Next, the racks 302 are released, and the elastic reset mechanism 4 pushes the two shafts 201 back to their original position, causing the baffles 202 to clamp the cell counting plate on both sides, providing additional fixation and ensuring the stability of the cell counting plate during testing – a double benefit. After the test is completed, the cell counting plate can be pulled out directly. Due to the frictional force, the baffle 202 can be deflected outward, thereby reducing the resistance to pulling the cell counting plate and making it easier to pull it out. Finally, the baffle 202 is reset and covers the surface of the inlet 101 to prevent dust in the air from entering the inlet 101 and causing a decrease in detection accuracy.

[0022] Figure 2 This is a partial cross-sectional structural diagram of the present invention. Figure 3 This is a cross-sectional structural diagram of the tube body in this utility model. Figure 4 This is a schematic diagram of the piston body in this utility model. Figure 2 , Figure 3 and Figure 4 As shown, the elastic reset mechanism 4 includes a fixed block 401 installed inside the housing 2. A spring 402 is connected to the surface of the fixed block 401. The end of the spring 402 is connected to the rack 302. When the pressure block 303 is pushed inward, the pressure block 303 drives the rack 302 to compress the spring 402 and store its force. When the pressure block 303 is released, the compressed spring 402 releases its elastic force, which can push the rack 302 to reset and drive the gear 301 to rotate in the opposite direction, so that the baffle 202 can once again cover the surface of the sample inlet 101. A tube body 403 is mounted on the outer surface of the fixing block 401. A guide rod 404 is slidably mounted inside the tube body 403, and the end of the guide rod 404 is connected to the rack 302. A spring 402 is sleeved on the outer surface of the tube body 403 and the guide rod 404. The guide rod 404 can extend and retract inside the tube body 403. Utilizing its extension and retraction characteristics, it can guide the spring 402 and prevent the tube body 403 from bending and deforming under the action of gravity. A piston body 405 is installed at the end of the guide rod 404 located inside the tube body 403. The surface of the piston body 405 is provided with multiple through holes 406. The inside of the tube body 403 is filled with oil. When the spring 402 pushes the rack 302 to reset, it drives the piston body 405 to move inside the tube body 403 through the guide rod 404. During the movement of the piston body 405, the oil flows through the through holes 406, which can produce a damping effect, reduce the flipping speed of the baffle 202, and allow it to slowly adhere to the surface of the injection port 101, avoiding impact vibration caused by rapid reset, which could damage the lens, light source, or sensor.

[0023] Example 2 Based on Embodiment 1, the present invention can be further improved in the following ways, such as... Figure 5 , Figure 6As shown, the end of the baffle 202 is provided with a beveled portion 203. When the cell counting plate is inserted into the sample inlet 101, the beveled portion 203 fits against the cell counting plate. The beveled portion 203 avoids the influence of thickness, preventing the two baffles 202 from failing to open when their ends are too close together. It also increases the clamping area of ​​the cell counting plate, further improving the stability during the detection process. A rubber layer is provided on the side of the baffle 202 facing the body 1. The rubber layer acts as a buffer when the baffle 202 contacts the surface of the sample inlet 101, further reducing the impact of impact.
