Description

Technical Field

[0001] The present invention relates to the technical field of cell detection and sampling, in particular to a cell detection and sampling device. Background Art

[0002] Hyperthermia is clinically known as a green therapy for tumor treatment. It mainly refers to the fact that this treatment method can control the growth and proliferation of tumors, kill tumor cells, and shrink tumors. Heating tumor cells is a commonly used method for studying tumor cells. During the research process, it is necessary to sample tumor cell samples at different temperatures to study the tumor's response at different temperatures.

[0003] In the prior art, when sampling cells, the cell culture device is generally opened and then sampled using a sampling probe. During this process, the cell culture device needs to be opened, which can easily cause foreign bacteria to enter the cell culture device. To address this issue, a Chinese patent with the existing patent publication number CN108753592B discloses a tumor cell heating device that can be used for sterile sampling. By setting a liftable drainage tube in the cell culture dish, sampling is achieved when the drainage tube is removed from the culture dish. Although this method does not require opening the culture dish, when the drainage tube extends out of the culture dish, it will come into contact with the outside air, thereby preventing the drainage tube from being attached to bacteria in the air. When the drainage tube enters the culture dish, it will cause the cells in the culture dish to be contaminated, affecting the normal cell culture and the next sampling, and thus affecting the test results. To address this problem, a cell detection sampling device is now proposed. Summary of the Invention

[0034] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0035] The present invention provides the following preferred embodiments: Example 1, as Figures 1-13 As shown, a cell detection sampling device includes a base 11, a detection table 12 and a vertical plate 13. The detection table 12 is fixedly mounted on the top of the base 11, and the vertical plate 13 is fixedly mounted on one side of the detection table 12. An incubator 15 is installed above the detection table 12. The incubator 15 is a device specifically used for culturing cells, tissues, and bacteria. The incubator 15 is a prior art and will not be described in detail here. It should be noted that in order to facilitate the study of tumor cells, the incubator 15 is provided with a temperature control system for heating the cells. Heating tumor cells is a commonly used method for studying tumor cells. During the research process, by sampling tumor cell samples at different temperatures, it is convenient to study the reaction of tumors at different temperatures. The device also includes a drainage tube 16, a blocking mechanism, a flushing mechanism, and a disinfection mechanism. The drainage tube 16 is integrally formed and arranged at the bottom end of the incubator 15. It should be noted that an avoidance groove 14 is provided on the detection table 12 for the drainage tube 16 to pass through; The blocking mechanism includes a blocking block 17, a lifting assembly, and a connecting assembly. The blocking block 17 is located inside the incubator 15, and the bottom end of the blocking block 17 is inserted into the top end of the drainage tube 16. The connecting assembly is slidably arranged on the top end of the incubator 15, and the bottom end of the connecting assembly is fixedly connected to the blocking block 17. The lifting assembly is located between the riser 13 and the connecting assembly. The drainage tube 16 can be blocked by the provided blocking block 17. When sampling is required, the sampling tube is first placed in the fixing frame 62. The blocking block 17 can be driven upward by the lifting assembly and the connecting assembly to release the blockage of the drainage tube 16. The two sealing covers 55 can be driven away from each other by the telescopic assembly, so that the drainage tube 16 can be drained smoothly. The drainage tube 16 can be used to drain the sample so that the sample can enter the sampling tube below to achieve sampling. The flushing mechanism includes an annular channel 50, a transmission assembly, an extraction assembly, an output assembly, and a plurality of output channels 51. The annular channel 50 is opened inside the blocking block 17. The plurality of output channels 51 are equidistantly arranged inside the blocking block 17. One end of each output channel 51 is connected to the annular channel 50. The output assembly is located above the detection table 12, and the output end of the output assembly is connected to the annular channel 50. The disinfection mechanism includes two sealing covers 55, two electric heating blocks 56 and a telescopic assembly. The two sealing covers 55 are symmetrically arranged on both sides of the drainage tube 16. Each electric heating block 56 is installed inside a sealing cover 55. The telescopic assembly can drive the two sealing covers 55 to approach each other, wrapping the drainage tube 16 in the two sealing covers 55, thereby achieving a sealing effect on the drainage tube 16.

[0036] like Figures 1-13 As shown, the connection assembly includes a lifting ring 19, two connecting blocks 20 and a plurality of lifting rods 18. The lifting ring 19 is located above the incubator 15. The plurality of lifting rods 18 are equidistantly slidably arranged on the top of the incubator 15. The two ends of each lifting rod 18 are respectively fixedly connected to the lifting ring 19 and the blocking block 17. The two connecting blocks 20 are symmetrically fixed on both sides of the lifting ring 19. When the lifting assembly is working, it can drive the two connecting blocks 20 to move, and the two connecting blocks 20 can drive the lifting ring 19 to move. When the lifting ring 19 moves, multiple lifting rods 18 can slide on the incubator 15, thereby driving the blocking block 17 to move.

[0037] like Figures 1-13 As shown, the lifting assembly includes a lifting frame 22, a first cylinder 52, two slide grooves 53, a plurality of first guide rods 21, a plurality of limit blocks 23 and a plurality of first springs 24. The two slide grooves 53 are both provided on the surface of the vertical plate 13. The lifting frame 22 is located above the lifting ring 19. One end of the lifting frame 22 is slidably disposed in the two slide grooves 53. The first cylinder 52 is fixed to one side of the vertical plate 13. The output end of the first cylinder 52 is fixedly connected to one end of the lifting frame 22. The first cylinder 52 can drive the lifting frame 22 to slide in the two slide grooves 53. Each first guide rod 21 is slidably mounted on a lifting frame 22. The top end of each first guide rod 21 is fixedly connected to a limit block 23. The bottom ends of every two first guide rods 21 are fixedly connected to a connecting block 20. Each first spring 24 is sleeved on the outside of a first guide rod 21. The two ends of each first spring 24 are respectively connected to the lifting frame 22 and the connecting block 20. In the initial state, the bottom end of the blocking block 17 is inserted into the interior of the drainage tube 16, and the first spring 24 is in a compressed state; When sampling is required, the controller controls the first cylinder 52 to work, and the first cylinder 52 can drive the lifting frame 22 to slide upward inside the two slide grooves 53. Since the first spring 24 is initially in a compressed state, when the lifting frame 22 slides upward, the first spring 24 gradually extends. As the lifting frame 22 continues to move upward, when the first spring 24 returns to a natural state, the top end of the lifting frame 22 contacts the bottom end of the first guide rod 21. As the lifting frame 22 continues to move, the lifting frame 22 can drive the connecting block 20 to move upward through the limit block 23 and the first guide rod 21. The connecting block 20 can drive the blocking block 17 to move upward through the lifting ring 19 and multiple lifting rods 18, thereby releasing the blockage of the drainage tube 16 and using the drainage tube 16 to achieve drainage, thereby achieving sampling.

[0038] like Figures 1-13 As shown, a storage box 45 is installed on the top of the detection table 12, and a water inlet pipe 44 is connected to the bottom of the storage box 45. A storage cylinder 42 mounted on the detection table 12 is provided on one side of the incubator 15. The other end of the water inlet pipe 44 is connected to the storage cylinder 42. An outlet pipe 43 is installed on the end of the storage cylinder 42 near the water inlet pipe 44. Both the outlet pipe 43 and the water inlet pipe 44 are equipped with a one-way valve. The extraction component is installed on the end of the storage cylinder 42 away from the outlet pipe 43, and the output component is located between the outlet pipe 43 and the annular channel 50. The storage tank 45 stores flushing water for cleaning the inner wall of the drainage pipe 16 .

[0039] like Figures 1-13 As shown, the transmission assembly includes an L-shaped rod 25, a pressure rod 26, a guide rail 27, a rack 28, a push rod 29, a top plate 30, a stop block 31, a limit plate 32, a second guide rod 33, a second spring 34 and a gear 35. The guide rail 27 is fixed to the top of the incubator 15. The rack 28 is slidably arranged inside the guide rail 27. The top of the rack 28 is fixedly connected to one end of the push rod 29. The other end of the push rod 29 is fixedly connected to the top plate 30. The stop block 31 is fixedly mounted on the top of the top plate 30. The limit plate 32 is fixed to one side of the guide rail 27. The second guide rod 33 is slidably arranged on the limit plate 32. The top of the second guide rod 33 is fixedly connected to the top plate 30. The second spring 34 is sleeved on the outside of the second guide rod 33. The two ends of the second spring 34 are respectively connected to the top plate 30 and the limit plate 32. The L-shaped rod 25 is fixed to the top of the lifting frame 22. The pressure rod 26 is located above the stop block 31. The top of the pressure rod 26 is fixedly connected to the end of the L-shaped rod 25 away from the lifting frame 22. The gear 35 is rotatably mounted on the top of the incubator 15. Specifically, a first mounting plate is fixed to the top of the incubator 15. The gear 35 is rotatably mounted on the first mounting plate. The gear 35 and the rack 28 are meshed with each other. In the initial state, the bottom end of the pressing rod 26 contacts the top end of the stop block 31, and the second spring 34 is in a compressed state; When the blockage of the drainage tube 16 needs to be released, that is, when the lifting frame 22 moves upward, the lifting frame 22 can drive the L-shaped rod 25 and the pressure rod 26 on the L-shaped rod 25 to move upward. Since the second spring 34 is initially in a compressed state, when the pressure rod 26 moves upward, it can drive the top plate 30 to move upward under the action of the second spring 34. The top plate 30 drives the rack 28 to slide upward inside the guide rail 27 through the top rod 29. When the rack 28 moves upward, it can drive the gear 35 to rotate.

[0040] like Figures 1-13 As shown, the extraction assembly includes a push rod 40, a push plate 41, a turntable 38, a hinged rod 39 and a synchronization component. The push rod 40 is slidably arranged at the end of the storage cylinder 42 away from the water outlet pipe 43, the push plate 41 slides inside the storage cylinder 42, one end of the push rod 40 is fixedly connected to the push plate 41, and the turntable 38 is rotatably arranged above the detection platform 12. Specifically, a second mounting plate is fixed above the detection platform 12, and the turntable 38 is rotatably arranged on the second mounting plate. One end of the hinged rod 39 is hinged to the end of the push rod 40 away from the push plate 41, and the other end of the hinged rod 39 is hinged to the surface of the turntable 38. The synchronization component is located between the turntable 38 and the gear 35; In the initial state, the push plate 41 is located inside the storage cylinder 42 on a side close to the water outlet pipe 43 . It should be noted that a through hole 46 is formed on the surface of one end of the storage cylinder 42 away from the water outlet pipe 43 .

[0041] like Figures 1-13 As shown, the synchronous components include a transmission belt 37 and two pulleys 36. The two pulleys 36 are respectively fixed to one side of the turntable 38 and the gear 35. That is, one pulley 36 is coaxially fixedly connected to the turntable 38, and the other pulley 36 is coaxially fixedly connected to the gear 35. The transmission belt 37 is sleeved on the outside of the two pulleys 36. When the rack 28 moves upward, it drives the gear 35 to rotate. The gear 35 drives the turntable 38 to rotate through the transmission belt 37 and two pulleys 36. Under the action of the hinged rod 39, the turntable 38 rotates and drives the push rod 40 to slide on the storage cylinder 42 toward the side away from the water outlet pipe 43, so that the push plate 41 can move toward the side away from the water outlet pipe 43. At this time, the flushing water in the storage box 45 can enter the storage cylinder 42 through the water inlet pipe 44 for storage. When sampling is completed, the sampling tube containing the sample is removed from the fixed frame 62, and then the controller controls the first cylinder 52 to work. The first cylinder 52 can drive the lifting frame 22 to slide downward inside the two slide grooves 53. When the lifting frame 22 moves, it can drive the L-shaped rod 25 and the pressure rod 26 on the L-shaped rod 25 to move downward. When the lifting frame 22 moves, it can drive the connecting block 20 to move downward through the first guide rod 21, the limit block 23, and the first spring 24. The connecting block 20 drives the blocking block 17 to move downward through the lifting ring 19 and multiple lifting rods 18, so that the blocking block 17 can be re-moved into the interior of the drainage tube 16 to block the drainage tube 16. At this time, the pressure rod 26 contacts the stop block 31. After the blocking block 17 blocks the drainage tube 16, the first cylinder 52 continues to work, causing the lifting frame 22 to continue to move downward, and the first spring 24 is compressed. When the lifting frame 22 continues to move downward, it can push the rack 28 to move downward inside the guide rail 27 through the L-shaped rod 25 and the pressure rod 26. At this time, the second spring 34 is compressed, and when the rack 28 moves downward, it can drive the gear 35 to rotate in the opposite direction. The gear 35 drives the turntable 38 to rotate in the opposite direction through the transmission belt 37 and two pulleys 36. Under the action of the hinged rod 39, it can drive the push rod 40 and the push plate 41 to move in the opposite direction, so that the flushing water stored in the storage cylinder 42 can be squeezed out through the outlet pipe 43.

[0042] like Figures 1-13 As shown, the output assembly includes a hose 47, an annular tube 48 and a plurality of strip-shaped channels 49. Each strip-shaped channel 49 is opened inside a lifting rod 18. The bottom end of each strip-shaped channel 49 is connected to the annular channel 50. The annular tube 48 is installed above the lifting ring 19. The top end of each lifting rod 18 is connected to the surface of the annular tube 48. The top end of each strip-shaped channel 49 is connected to the interior of the annular tube 48. One end of the hose 47 is connected to the annular tube 48, and the other end of the hose 47 is connected to the water outlet pipe 43. The flushing water squeezed out through the outlet pipe 43 enters the interior of the hose 47, then passes through the annular pipe 48 and multiple strip-shaped channels 49, so that the flushing water is collected in the annular channel 50, and finally flows out through multiple output channels 51 to the inner wall of the drainage tube 16, thereby flushing the inner wall of the drainage tube 16 after sampling; That is, after each sampling is completed, the blocking block 17 can block the drainage tube 16. After the blocking block 17 blocks the drainage tube 16, the drainage tube 16 can be cleaned and disinfected, so that when the next sampling is taken, the drainage tube 16 can be in a clean state, avoiding the drainage tube 16 from contaminating the next group of samples taken out, which is beneficial to improving the detection accuracy of the samples.

[0043] like Figures 1-13As shown, the telescopic assembly includes a rotating rod 60, a second cylinder 54, two guide bars 58, two moving blocks 59, two connecting rods 61 and two connecting frames 57. The two guide bars 58 are fixed to the bottom end of the detection platform 12, and each moving block 59 is slidably set on the two guide bars 58. The second cylinder 54 is installed at the bottom end of the detection platform 12, and the output end of the second cylinder 54 is connected to one of the moving blocks 59. The middle part of the rotating rod 60 is rotatably set at the bottom end of the detection platform 12 through a rotating shaft. The two connecting rods 61 are respectively hinged at both ends of the rotating rod 60, and the other end of each connecting rod 61 is hinged to a moving block 59. The two connecting frames 57 are respectively fixed to the side of the two sealing covers 55 away from each other, and each connecting frame 57 is installed on a moving block 59. Before sampling is required, the controller first controls the second cylinder 54 to work, and the second cylinder 54 drives the moving block 59 connected to the output end of the second cylinder 54 to move. Under the action of the rotating rod 60 and the two connecting rods 61, the other moving block 59 can be driven to move, so that the two moving blocks 59 can move away from each other. At this time, the two connecting frames 57 can drive the two sealing covers 55 to move away from each other, so that the drainage tube 16 can smoothly achieve drainage. After the internal flushing of the drainage tube 16 is completed, the telescopic assembly can be used to drive the two sealing covers 55 closer to each other, and the drainage tube 16 is wrapped in the two sealing covers 55 to achieve a sealing effect on the drainage tube 16. The space inside the two sealing covers 55 is heated by the electric heating block 56. On the one hand, the flushing water on the inner wall of the drainage tube 16 can be dried. On the other hand, during heating, high-temperature sterilization of the drainage tube 16 can be achieved to prevent the drainage tube 16 from being contaminated by bacteria in the air and causing contamination to the sample taken out next time.

[0044] like Figures 1-13 As shown, a fixing frame 62 is provided below the drainage tube 16 , and the pressure rod 26 is detachably mounted on the top of the base 11 . Specifically, the fixing frame 62 is a test tube rack.

[0045] The specific working process of the present invention is as follows: When sampling is required, the sampling tube is first placed in the fixed frame 62. First, the controller controls the second cylinder 54 to work, and the second cylinder 54 drives the moving block 59 connected to the output end of the second cylinder 54 to move. Under the action of the rotating rod 60 and the two connecting rods 61, the other moving block 59 can be driven to move, so that the two moving blocks 59 can move away from each other. At this time, the two connecting frames 57 can drive the two sealing covers 55 to move away from each other, so that the drainage tube 16 can smoothly achieve drainage. The controller controls the operation of the first cylinder 52, which can drive the lifting frame 22 to slide upward inside the two slide grooves 53. Since the first spring 24 is initially in a compressed state, when the lifting frame 22 slides upward, the first spring 24 gradually extends. As the lifting frame 22 continues to move upward, when the first spring 24 returns to its natural state, the top end of the lifting frame 22 contacts the bottom end of the first guide rod 21. As the lifting frame 22 continues to move, the lifting frame 22 can drive the connecting block 20 to move upward through the limit block 23 and the first guide rod 21. The connecting block 20 can drive the blocking block 17 to move upward through the lifting ring 19 and the multiple lifting rods 18, thereby releasing the blockage of the drainage tube 16 and utilizing the drainage tube 16 to achieve drainage, thereby achieving sampling. When the lifting frame 22 moves upward, the lifting frame 22 can drive the L-shaped rod 25 and the pressure rod 26 on the L-shaped rod 25 to move upward. Since the second spring 34 is initially in a compressed state, when the pressure rod 26 moves upward, it can drive the top plate 30 to move upward under the action of the second spring 34. The top plate 30 drives the rack 28 to slide upward inside the guide rail 27 through the top rod 29. When the rack 28 moves upward, it can drive the gear 35 to rotate. The gear 35 can drive the turntable 38 to rotate through the transmission belt 37 and the two pulleys 36. Under the action of the hinged rod 39, when the turntable 38 rotates, it can drive the push rod 40 to slide on the storage cylinder 42 toward the side away from the water outlet pipe 43, so that the push plate 41 can move toward the side away from the water outlet pipe 43. At this time, the flushing water inside the storage box 45 can enter the interior of the storage cylinder 42 through the water inlet pipe 44 for storage. When sampling is completed, the sampling tube containing the sample is removed from the fixed frame 62, and then the controller controls the first cylinder 52 to work. The first cylinder 52 can drive the lifting frame 22 to slide downward inside the two slide grooves 53. When the lifting frame 22 moves, it can drive the L-shaped rod 25 and the pressure rod 26 on the L-shaped rod 25 to move downward. When the lifting frame 22 moves, it can drive the connecting block 20 to move downward through the first guide rod 21, the limit block 23, and the first spring 24. The connecting block 20 drives the blocking block 17 to move downward through the lifting ring 19 and multiple lifting rods 18, so that the blocking block 17 can be re-moved into the interior of the drainage tube 16 to block the drainage tube 16. At this time, the pressure rod 26 contacts the stop block 31. After the blocking block 17 blocks the drainage tube 16, the first cylinder 52 continues to work, causing the lifting frame 22 to continue to move downward, and the first spring 24 is compressed. When the lifting frame 22 continues to move downward, it can push the rack 28 to move downward inside the guide rail 27 through the L-shaped rod 25 and the pressure rod 26. At this time, the second spring 34 is compressed, and when the rack 28 moves downward, it can drive the gear 35 to rotate in the opposite direction. The gear 35 drives the turntable 38 to rotate in the opposite direction through the transmission belt 37 and the two pulleys 36. Under the action of the hinged rod 39, it can drive the push rod 40 and the push plate 41 to move in the opposite direction, so that the flushing water stored in the storage cylinder 42 can be squeezed out through the water outlet pipe 43. The flushing water squeezed out through the water outlet pipe 43 enters the interior of the hose 47, and then passes through the annular pipe 48 and multiple strip channels 49, so that the flushing water is collected in the annular channel 50. Finally, the flushing water flows out through multiple output channels 51 to the inner wall of the drainage pipe 16, thereby flushing the inner wall of the drainage pipe 16 after sampling. That is, after each sampling is completed, the blocking block 17 can block the drainage tube 16. After the blocking block 17 blocks the drainage tube 16, the drainage tube 16 can be cleaned and disinfected, so that when the next sampling is taken, the drainage tube 16 can be in a clean state, avoiding the drainage tube 16 from contaminating the next group of samples taken out, which is conducive to improving the detection accuracy of the samples; After the internal flushing of the drainage tube 16 is completed, the telescopic assembly can be used to drive the two sealing covers 55 closer to each other, and the drainage tube 16 is wrapped in the two sealing covers 55 to achieve a sealing effect on the drainage tube 16. The space inside the two sealing covers 55 is heated by the electric heating block 56. On the one hand, the flushing water on the inner wall of the drainage tube 16 can be dried. On the other hand, during heating, high-temperature sterilization of the drainage tube 16 can be achieved to prevent the drainage tube 16 from being contaminated by bacteria in the air and causing contamination to the sample taken out next time.
