Description

Technical Field

[0001] This invention relates to the field of cell detection and sampling technology, specifically a cell detection and sampling device. Background Technology

[0002] Hyperthermia is clinically known as a green therapy for cancer treatment. This is mainly because this treatment method can control the growth and proliferation of tumors, kill tumor cells, and shrink tumors. Heating tumor cells is a common method for studying tumor cells. In the research process, it is necessary to sample tumor cells at different temperatures and study the tumor's response at different temperatures.

[0003] In the existing technology, when sampling cells, the cell culture device is usually turned on and then a sampling probe is used to take the sample. During this process, the cell culture device needs to be turned on, which can easily cause foreign bacteria to enter the cell culture device.

[0004] To address this issue, Chinese Patent Publication No. CN108753592B discloses a heating device for aseptic sampling of tumor cells. This device uses a liftable drainage tube within a cell culture dish. Sampling is achieved when the drainage tube is removed from the dish. While this method eliminates the need to open the culture dish, the drainage tube comes into contact with air when it extends outside, preventing the tube from accumulating airborne bacteria. When the drainage tube re-enters the culture dish, it contaminates the cells, affecting normal cell culture and subsequent sampling, ultimately impacting test results. To address this problem, a cell detection and sampling device is proposed. Summary of the Invention

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. A cell detection sampling device of the present invention, by setting a sealing mechanism, can seal the drainage tube by setting a sealing block. When sampling is required, the lifting component and the connecting component drive the sealing block to move upward, release the sealing of the drainage tube, and use the drainage tube to drain the sample to realize sampling. During the sampling process, the possibility of contact between the inside of the incubator and the outside world can be effectively reduced, the possibility of cell contamination in the incubator can be reduced, and the accuracy of sampling and detection can be improved.

[0025] 2. A cell detection sampling device of the present invention, by setting a rinsing mechanism, allows rinsing water inside the storage tank to enter and exit the storage cylinder during sampling as the sealing block moves upward. After each sampling is completed, the sealing block seals the drainage tube, and the rinsing water inside the storage cylinder can flow out through several output channels on the sealing block, allowing the rinsing water to flow to the inner wall of the drainage tube, thereby rinsing the inner wall of the drainage tube after sampling, avoiding the influence of residual sample on the inner wall of the drainage tube on the next sampling, and improving the detection accuracy.

[0026] 3. The cell detection sampling device of the present invention, through the set disinfection mechanism, after the internal rinsing of the drainage tube is completed, uses the telescopic component to drive the two sealing covers to come closer together, wrapping the drainage tube in the two sealing covers to achieve a sealing effect on the drainage tube. The space inside the two sealing covers is heated by the electric heating block, which on the one hand dries the rinsing water on the inner wall of the drainage tube, and on the other hand, achieves high-temperature sterilization of the drainage tube during heating, so as to avoid the drainage tube being contaminated with bacteria in the air and causing contamination of the sample taken next time.

[0027] 4. The cell detection sampling device of the present invention, combined with a rinsing mechanism and a disinfection mechanism, can clean and disinfect the drainage tube after each sampling, so that the drainage tube is in a clean state when sampling next, avoiding contamination of the next batch of samples by the drainage tube, and improving the detection accuracy of the samples.

[0028] 5. A cell detection sampling device of the present invention, through a transmission component, when sampling is required, the blocking block moves upward to release the anti-blocking of the drainage tube. At this time, under the action of the transmission component, flushing water enters the interior of the storage cylinder. After sampling is completed, the blocking block moves back into the interior of the drainage tube to block the drainage tube. At this time, under the action of the transmission component, the flushing water inside the storage cylinder can be squeezed out to flush the interior of the drainage tube. The synchronization is high and meets the usage requirements. Attached Figure Description

[0043] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0044] The present invention provides the following preferred embodiments:

[0045] Example 1, as Figures 1-13 As shown, a cell detection and sampling device includes a base 11, a detection platform 12, and a vertical plate 13. The detection platform 12 is fixedly installed on the top of the base 11, and the vertical plate 13 is fixedly installed on one side of the detection platform 12. An incubator 15 is installed above the detection platform 12. The incubator 15 is a device specifically used for cell, tissue, and bacterial culture. The incubator 15 is existing technology 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 equipped with a temperature control system for heating the cells. Heating tumor cells is a common method for studying tumor cells. During the research process, tumor cell samples at different temperatures are sampled to facilitate the study of the tumor's response at different temperatures. The device also includes a drainage tube 16, a sealing mechanism, a flushing mechanism, and a disinfection mechanism.

[0046] The drainage tube 16 is integrally formed and set at the bottom of the incubator 15. It should be noted that the detection table 12 is provided with a relief groove 14 for the drainage tube 16 to pass through.

[0047] 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 disposed at 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 vertical plate 13 and the connecting assembly.

[0048] The blocking block 17 can block the drainage tube 16. When sampling is required, the sampling tube is first placed in the fixed frame 62. The lifting component and the connecting component can drive the blocking block 17 to move upward, thereby releasing the blockage of the drainage tube 16. The telescopic component can drive the two sealing covers 55 to move away from each other, so that the drainage tube 16 can smoothly drain. The drainage tube 16 can be used to drain the sample, so that the sample can enter the sampling tube below to achieve sampling.

[0049] The flushing mechanism includes an annular channel 50, a transmission assembly, an extraction assembly, an output assembly, and several output channels 51. The annular channel 50 is located inside the sealing block 17. Several output channels 51 are equidistantly arranged inside the sealing 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.

[0050] The disinfection mechanism includes two sealing covers 55, two electric heating blocks 56, and a telescopic component. The two sealing covers 55 are symmetrically arranged on both sides of the drainage tube 16. Each electric heating block 56 is installed inside one sealing cover 55. The telescopic component can drive the two sealing covers 55 to move closer to each other, wrapping the drainage tube 16 in the two sealing covers 55, thereby achieving a sealing effect on the drainage tube 16.

[0051] like Figures 1-13 As shown, the connecting assembly includes a lifting ring 19, two connecting blocks 20 and multiple lifting rods 18. The lifting ring 19 is located above the incubator 15. The multiple lifting rods 18 are equidistantly slidably arranged at the top of the incubator 15. Both ends of each lifting rod 18 are fixedly connected to the lifting ring 19 and the sealing block 17, respectively. The two connecting blocks 20 are symmetrically fixed on both sides of the lifting ring 19.

[0052] When the lifting assembly is working, it can drive the two connecting blocks 20 to move. 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 sealing block 17 to move.

[0053] like Figures 1-13As shown, the lifting assembly includes a lifting frame 22, a first cylinder 52, two slide grooves 53, multiple first guide rods 21, multiple limit blocks 23, and multiple first springs 24. Both slide grooves 53 are formed 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.

[0054] Each first guide rod 21 is slidably mounted on the lifting frame 22. The top end of each first guide rod 21 is fixedly connected to a limiting 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. Both ends of each first spring 24 are respectively connected to the lifting frame 22 and the connecting block 20.

[0055] In the initial state, the bottom end of the blocking block 17 is inserted into the inside of the drainage tube 16, and the first spring 24 is in a compressed state;

[0056] When sampling is required, the controller controls the first cylinder 52 to work. 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 its natural state, the top of the lifting frame 22 contacts the bottom 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 limiting block 23 and the first guide rod 21. The connecting block 20 can drive the sealing block 17 to move upward through the lifting ring 19 and multiple lifting rods 18, releasing the blockage of the drainage pipe 16 and using the drainage pipe 16 to achieve drainage, thereby realizing sampling.

[0057] like Figures 1-13 As shown, a storage box 45 is installed at the top of the detection platform 12, and an inlet pipe 44 is connected to the bottom of the storage box 45. A storage cylinder 42 is installed on one side of the incubator 15 on the detection platform 12. The other end of the inlet pipe 44 is connected to the storage cylinder 42. An outlet pipe 43 is installed at the end of the storage cylinder 42 near the inlet pipe 44. A one-way valve is installed on both the outlet pipe 43 and the inlet pipe 44. The extraction component is installed at the end of the storage cylinder 42 away from the outlet pipe 43. The output component is located between the outlet pipe 43 and the annular channel 50.

[0058] The storage tank 45 contains flushing water for cleaning the inner wall of the drainage tube 16.

[0059] like Figures 1-13As shown, the transmission assembly includes an L-shaped rod 25, a pressure rod 26, a guide rail 27, a rack 28, a top rod 29, a top plate 30, a stop block 31, a limiting 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 disposed inside the guide rail 27. The top end of the rack 28 is fixedly connected to one end of the top rod 29. The other end of the top rod 29 is fixedly connected to the top plate 30. The stop block 31 is fixedly installed on the top of the top plate 30. The limiting plate 32 is fixed to one side of the guide rail 27. The second guide rod 33 is slidably disposed on the limiting plate 32. The top end 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 limiting plate 32.

[0060] L-shaped rod 25 is fixed to the top of lifting frame 22, pressure rod 26 is located above abutment block 31, and the top of pressure rod 26 is fixedly connected to the end of L-shaped rod 25 away from lifting frame 22. Gear 35 is rotatably mounted on the top of incubator 15. Specifically, the top of incubator 15 is fixed with a first mounting plate, and gear 35 is rotatably mounted on the first mounting plate. Gear 35 meshes with rack 28.

[0061] In the initial state, the bottom end of the pressure rod 26 is in contact with the top end of the abutment block 31, and the second spring 34 is in a compressed state;

[0062] When it is necessary to unblock the drainage tube 16, 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.

[0063] like Figures 1-13 As shown, the extraction assembly includes a push rod 40, a push plate 41, a turntable 38, a hinge rod 39, and a synchronization component. The push rod 40 is slidably disposed 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. The turntable 38 is rotatably disposed above the detection platform 12. Specifically, a second mounting plate is fixed above the detection platform 12, and the turntable 38 is rotatably disposed on the second mounting plate. One end of the hinge rod 39 is hinged to the end of the push rod 40 away from the push plate 41, and the other end of the hinge rod 39 is hinged to the surface of the turntable 38. The synchronization component is located between the turntable 38 and the gear 35.

[0064] In the initial state, the push plate 41 is located inside the storage cylinder 42 on the side close to the water outlet pipe 43. It should be noted that a through hole 46 is opened on the surface of the storage cylinder 42 away from the water outlet pipe 43.

[0065] like Figures 1-13 As shown, the synchronization component includes a transmission belt 37 and two pulleys 36. The two pulleys 36 are fixed to one side of the turntable 38 and the gear 35, respectively. 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.

[0066] 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 two pulleys 36. Under the action of the hinge rod 39, when the turntable 38 rotates, it can drive the push rod 40 to slide on the storage cylinder 42 away from the water outlet pipe 43, so that the push plate 41 can move away from the water outlet pipe 43. At this time, the rinsing water inside the storage box 45 can enter the storage cylinder 42 through the water inlet pipe 44 for storage.

[0067] After sampling is completed, the sampling tube containing the sample is removed from the fixing frame 62. 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 limiting block 23, and the first spring 24. The connecting block 20 drives the sealing block 17 to move downward through the lifting ring 19 and multiple lifting rods 18, so that the sealing block 17 can move back into the interior of the drainage tube 16 to seal the drainage tube 16. At this time, the pressure rod 26 contacts the abutment block 31.

[0068] After the blocking block 17 blocks the drainage pipe 16, the first cylinder 52 continues to work, causing the lifting frame 22 to continue to move down, at which time the first spring 24 is compressed;

[0069] As 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. 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 hinge rod 39, it can drive the push rod 40 and the push plate 41 to move in the opposite direction, so that the rinsing water stored inside the storage cylinder 42 can be squeezed out through the water outlet pipe 43.

[0070] like Figures 1-13As shown, the output assembly includes a hose 47, an annular tube 48, and multiple strip channels 49. Each strip channel 49 is opened inside a lifting rod 18. The bottom end of each strip channel 49 is connected to an 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 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 outlet pipe 43.

[0071] The flushing water squeezed out through the 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 several outlet channels 51 to the inner wall of the drainage pipe 16, thereby flushing the inner wall of the drainage pipe 16 after sampling.

[0072] 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 the drainage tube 16 can be in a clean state when sampling next, avoiding the drainage tube 16 from contaminating the next batch of samples, which is conducive to improving the detection accuracy of the samples.

[0073] like Figures 1-13 As 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 of the testing table 12. Each moving block 59 is slidably mounted on the two guide bars 58. The second cylinder 54 is mounted on the bottom of the testing table 12. 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 mounted on the bottom of the testing table 12 via a rotating shaft. The two connecting rods 61 are respectively hinged to the two ends of the rotating rod 60. 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 two sealing covers 55 on opposite sides. Each connecting frame 57 is mounted on a moving block 59.

[0074] Before sampling is required, the controller first controls the second cylinder 54 to work. 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, it can drive another moving block 59 to move, so that the two moving blocks 59 can move in a direction away from each other. At this time, the two connecting frames 57 can drive the two sealing covers 55 to move in a direction away from each other, so that the drainage tube 16 can smoothly achieve drainage.

[0075] After the drainage tube 16 is rinsed inside, the telescopic component can be used to move the two sealing covers 55 closer together, wrapping the drainage tube 16 in the two sealing covers 55 to achieve a sealing effect. The electric heating block 56 heats the space inside the two sealing covers 55, which on the one hand dries the rinsing water on the inner wall of the drainage tube 16, and on the other hand, the high temperature sterilization of the drainage tube 16 can be achieved during heating, so as to prevent the drainage tube 16 from being contaminated by bacteria in the air and causing contamination of the next sample taken out.

[0076] like Figures 1-13 As shown, a fixing frame 62 is provided below the drainage tube 16, and the pressure rod 26 is detachably installed on the top of the base 11. Specifically, the fixing frame 62 is a test tube rack.

[0077] The specific working process of this invention is as follows:

[0078] When sampling is required, the sampling tube is first placed in the fixed frame 62. The controller first controls the second cylinder 54 to work. 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, it can drive another moving block 59 to move, so that the two moving blocks 59 can move in a direction away from each other. At this time, the two connecting frames 57 can drive the two sealing covers 55 to move in a direction away from each other, so that the drainage tube 16 can smoothly achieve drainage.

[0079] The controller controls the first cylinder 52 to work. 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 its natural state, the top of the lifting frame 22 contacts the bottom 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 limiting block 23 and the first guide rod 21. The connecting block 20 can drive the sealing block 17 to move upward through the lifting ring 19 and multiple lifting rods 18, thereby releasing the blockage of the drainage pipe 16 and realizing drainage through the drainage pipe 16, thus realizing sampling.

[0080] When the lifting frame 22 moves upward, it 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 push 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 two pulleys 36. Under the action of the hinge rod 39, when the turntable 38 rotates, it can drive the push rod 40 to slide on the storage cylinder 42 away from the water outlet pipe 43, so that the push plate 41 can move away from the water outlet pipe 43. At this time, the flushing water inside the storage box 45 can enter the storage cylinder 42 through the water inlet pipe 44 for storage.

[0081] After sampling is completed, the sampling tube containing the sample is removed from the fixing frame 62. 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 limiting block 23, and the first spring 24. The connecting block 20 drives the sealing block 17 to move downward through the lifting ring 19 and multiple lifting rods 18, so that the sealing block 17 can move back into the interior of the drainage tube 16 to seal the drainage tube 16. At this time, the pressure rod 26 contacts the abutment block 31.

[0082] After the blocking block 17 blocks the drainage pipe 16, the first cylinder 52 continues to work, causing the lifting frame 22 to continue to move down, at which time the first spring 24 is compressed;

[0083] As 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. 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 hinge 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 inside 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 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 several output channels 51 to the inner wall of the drainage pipe 16, realizing the flushing of the inner wall of the sampling drainage pipe 16.

[0084] 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 the drainage tube 16 can be in a clean state when sampling next, avoiding the drainage tube 16 from contaminating the next batch of samples, which is conducive to improving the detection accuracy of the samples.

[0085] After the drainage tube 16 is rinsed inside, the telescopic component can be used to move the two sealing covers 55 closer together, wrapping the drainage tube 16 in the two sealing covers 55 to achieve a sealing effect. The electric heating block 56 heats the space inside the two sealing covers 55, which on the one hand dries the rinsing water on the inner wall of the drainage tube 16, and on the other hand, the high temperature sterilization of the drainage tube 16 can be achieved during heating, so as to prevent the drainage tube 16 from being contaminated by bacteria in the air and causing contamination of the next sample taken out.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
