Description

Technical Field

[0001] The present invention relates to the technical field of single cell culture, in particular to a single cell culture device and a method thereof. Background Art

[0002] Single-cell culture refers to the technology of isolating single cells from plant organs, callus tissue or suspension cultures and growing and developing them in vitro under sterile conditions. People had the idea and practice of isolating and culturing single plant cells relatively early, but successful single-cell culture was only achieved with the development of more effective culture media and the establishment of specialized techniques for isolating single cells from callus tissue suspension cultures.

[0003] In the prior art, there is a cell culture device suitable for single cells proposed in patent application number "CN201911118766.9". When the culture dish accidentally falls from the test bench, the bottom end of the culture dish will fall vertically due to the weight of the circular metal weight block, which can effectively prevent the top end from falling vertically, so as to prevent the culture fluid in the culture dish from contacting the dish cover and flowing out from the air vent. The dish cover and the culture dish are connected by a rubber ball A and an outer annular arc-shaped limit groove, so as to ensure that the dish cover will not be separated from the culture dish when the culture dish falls.

[0004] However, in the above patent application, when culturing single cells, it is usually necessary to oscillate the single cells together with the culture medium so that the cells can be evenly fused with the culture medium to improve the culture efficiency. However, nowadays, when culturing single cells, it is generally only done by manual oscillation, and the adequacy of the oscillation cannot be guaranteed.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] A single cell culture device and method thereof, such as Figure 1-Figure 9 As shown, it includes an oscillation barrel 1 and a carrier 3, the upper end surface of the carrier 3 is fixedly mounted with a shell 2, the outer wall of the shell 2 is inserted with two slide bars 7, and one end of the two slide bars 7 is fixedly connected to the oscillation barrel 1, and a buffer spring is sleeved on the outside of the two slide bars 7 and located between the outer wall of the oscillation barrel 1 and the inner wall of the shell 2. A circular plate 2 12 is fixedly mounted near the bottom of the oscillation barrel 1, a placing table 5 is movably mounted above the circular plate 2 12, an auxiliary mechanism is arranged between the bottom surface of the placing table 5 and the upper end surface of the circular plate 2 12, an annular plate 14 is fixedly connected to the bottom surface of the placing table 5, a plurality of circular slots are opened on the upper end surface of the annular plate 14, and test tubes 38 are inserted in the plurality of circular slots, a circular plate 1 8 is fixedly mounted on the upper end surface of the carrier 3, a plurality of culture dishes 9 are fixedly mounted on the upper end surface of the circular plate 1 8, a vertical shaft 28 is rotatably connected to the upper end surface of the circular plate 1 8 near the middle, and a clamping mechanism is arranged on the upper end surface of the vertical shaft 28.

[0040] The bottom end of the oscillation barrel 1 is rotatably connected to an eccentric wheel 11 through an axis rod. A motor 1 is installed on the bottom surface of the oscillation barrel 1, and the output end of the motor 1 is connected to the eccentric wheel 11. Two telescopic push rods 13 are fixedly connected to the upper end surface of the circular plate 2 12, and the upper ends of the two telescopic push rods 13 are fixedly connected to the placement table 5. The two telescopic push rods 13 are both sleeved with support springs on the outside. When the platform 3 moves back and forth vertically and generates vertical vibration force, the two telescopic push rods 13 are repeatedly stretched and compressed following the placement table 5, and the support springs are repeatedly stretched and compressed accordingly, which plays a role in limiting and supporting the vertical moving position of the placement table 5, so that the placement table 5 can maintain a vertical direction and move back and forth up and down.

[0041] like Figure 7 As shown, the auxiliary mechanism includes a bevel gear 26 and two mounting plates 21. The bevel gear 26 is rotatably connected to the upper end surface of the circular plate 12 through an axle. Both mounting plates 21 are fixedly installed on the upper end surface of the circular plate 12, and the bevel gear 26 is connected to the eccentric wheel 11 through the axle.

[0042] The outer side walls of the two mounting plates 21 are rotatably connected to a short shaft 22, one end of the short shaft 22 is fixedly connected to a bevel gear 1 23, the bevel gear 1 23 and the bevel gear 2 26 are meshed with each other, the other end of the short shaft 22 is fixedly connected to a turntable 34, the outer side wall of the turntable 34 is rotatably connected to a connecting rod 1 24 via an axle rod, the end of the connecting rod 1 24 away from the turntable 34 is rotatably connected to a connecting rod 25 via an axle rod, and the upper end of the connecting rod 25 is fixedly connected to the placement table 5.

[0043] A plurality of placement grooves 17 are provided on the outer wall of the placement table 5. A connecting shaft 15 is rotatably connected to the upper surface of the placement table 5 near the middle position. A central gear 39 is fixedly connected to the outer wall of the connecting shaft 15 near the bottom position. A second motor is installed on the bottom surface of the placement table 5, and the output end of the second motor is connected to the connecting shaft 15. Clamps 18 are installed on the edge positions of the plurality of placement grooves 17 on the upper surface of the placement table 5, and one of the clamps 18 is fixedly connected to the upper surface of the placement table 5, and the other clamp 18 is movably installed on the upper surface of the placement table 5. One end of one of the clamps 18 is fixedly connected to a movable plate 20, and the movable plate 20 is rotatably connected to the placement table 5 through a shaft. The upper surface of the movable plate 20 is fixedly connected with a transmission gear 19 through an axis rod, and the transmission gear 19 and the center gear 39 are meshed with each other. The internal space size of the placement groove 17 matches the test tube 38. After the test tube 38 is placed in the placement groove 17, the inner wall of the placement groove 17 fits tightly with the outer wall of the test tube 38, and with the friction force, the position of the test tube 38 can be initially limited. The upper part of the connecting shaft 15 is a retractable structure. The oscillation barrel 1 moves back and forth up and down, and the upper part of the connecting shaft 15 continuously shrinks and stretches accordingly, which will not hinder the vertical movement of the oscillation barrel 1, and the retractable section of the connecting shaft 15 is engaged with the card strip and can rotate synchronously.

[0044] When in use, the cells to be cultured are transferred into the test tube 38, and after the culture solution is injected and sealed, it is clamped in the placement groove 17 opened on the placement table 5. Similarly, multiple test tubes 38 with single cells and culture solution can be clamped in other placement grooves 17 in sequence, and at this time, the test tube 38 is placed close to one of the clamping plates 18 fixed on the upper surface of the placement table 5, and then the connecting shaft 15 is driven to rotate by the second motor, thereby driving the central gear 39 to rotate, and can simultaneously drive each transmission gear 19 to rotate, thereby driving the movable plate Another clamping plate 18 connected to 20 is rotated to a position where its inner wall is close to the outer wall of the test tube 38, so as to clamp and fix the test tube 38. Similarly, several other test tubes 38 can be clamped and fixed at the same time, and then the eccentric wheel 11 is driven to rotate by the motor 1. The centrifugal force generated by the rotation of the eccentric wheel 11 causes the oscillation barrel 1 to reciprocate left and right through the slide rod 7. The two slide rods 7 continuously slide left and right on the slide rod 7, and the buffer spring is continuously compressed and stretched accordingly, so that the oscillation barrel 1 generates a lateral vibration force, and each test tube 38 is vibrated laterally.

[0045] When the eccentric wheel 11 rotates, the bevel gear 26 rotates accordingly, driving the two bevel gears 1 23 to rotate, thereby driving the turntable 34 connected by the two short shafts 22 to rotate, so that one end of the connecting rod 1 24 rotates with the turntable 34 and moves in a circular trajectory, and the other end of the connecting rod 1 24 rotates with the connecting rod 2 25, and can drive the connecting rod 2 25 to reciprocate in the vertical direction, thereby driving the placement table 5 to reciprocate up and down, generating a vertical vibration force, and vibrating each test tube 38 vertically;

[0046] Through the above operation, the test tube 38 can be vibrated horizontally and vertically at the same time, so that the cells and the culture solution can be fully oscillated and fused.

[0047] The upper end of the connecting shaft 15 is rotatably connected to the ratchet 16 through the shaft rod, and the bottom surface of the ratchet 16 is provided with a limiting groove 30. The outer wall of the connecting shaft 15 is rotatably connected to the limiting block 31 located inside the limiting groove 30, and the limiting block 31 and the limiting groove 30 are meshed with each other. The upper end surface of the housing 2 is fixedly connected to the bracket 6, and the upper end surface of the ratchet 16 is fixedly connected to the transmission shaft 40, and the upper end of the transmission shaft 40 is rotatably connected to the top position inside the bracket 6. The outer wall of the housing 2 is rotatably connected to the long shaft 27, and the long shaft A transmission belt 2 33 is sleeved between the vertical axis 27 and the outside of the transmission shaft 40, and a transmission belt 1 32 is sleeved between the vertical axis 28 and the outside of the long axis 27. The connection shaft 15 rotates to drive the clamping plate 18 to rotate toward the test tube 38. When the test tube 38 is clamped, the limit block 31 rotates accordingly, but is restricted by the shape of the limit groove 30 and cannot drive the ratchet 16 to rotate. When the connection shaft 15 rotates in the opposite direction to drive the clamping plate 18 to rotate away from the test tube 38, the limit block 31 cooperates with the limit groove 30 to drive the ratchet 16 to rotate.

[0048] Two frames 10 are fixedly connected to the inner wall of the outer shell 2 and the lower position of the oscillation barrel 1. Slide plates 35 are slidably connected inside the two frames 10, and the upper ends of the two slide plates 35 are fixedly connected to the oscillation barrel 1. When the oscillation barrel 1 moves back and forth left and right, the two slide plates 35 follow the movement and move along the inside of the two frames 10, thereby playing a load-bearing and position-limiting role for the oscillation barrel 1.

[0049] The clamping mechanism includes a connecting rod 29, which is fixedly connected to the upper surface of the vertical shaft 28. One end of the connecting rod 29 is matched with the bottom end of the slide 35. Both outer walls of the slide 35 are provided with movable grooves near the bottom. Blocks 36 are inserted into the two movable grooves. Both inner walls of the connecting rod 29 are provided with clamping grooves 37, and the clamping grooves 37 are matched with the clamping blocks 36. A limiting spring is installed between one end of the clamping block 36 and the inner wall of the movable groove.

[0050] Specifically, after each test tube 38 is automatically oscillated, the connecting shaft 15 is reversed by the second motor, which can drive the clamping plate 18 to rotate away from the test tube 38, release the clamping fixation of the test tube 38, and then put each single cell after each oscillation and fusion into each culture dish 9 in turn, and add the corresponding culture fluid to transfer the single cell to the culture dish 9 for culture. During the rotation of the clamping plate 18 to release the clamping fixation of the test tube 38, the limit block 31 rotates with the connecting shaft 15, cooperates with the limit groove 30, can drive the ratchet 16 to rotate, and the transmission shaft 40 rotates accordingly, thereby driving the transmission belt 2 33 to transmit, and then driving the long shaft 27 to rotate, so that the transmission belt 1 32 transmits, driving the vertical shaft 28 to rotate, and the connecting rod 29 in the clamping mechanism rotates accordingly, so that the end of the connecting rod 29 away from the vertical shaft 28 is clamped and fixed with the bottom of the slide plate 35;

[0051] During the engagement process, the inclined surfaces of the two blocks 36 contact the inner wall of the connecting rod 29, and gradually shrink into the movable groove under the action of the connecting rod 29 rotating and engaging, and the limit spring is compressed. When one end of the connecting rod 29 is completely engaged with the bottom of the slide plate 35, one end of the block 36 is directly opposite to the side of the slot 37. Under the action of the rebound force of the limit spring, one end of the block 36 can be inserted into the slot 37 to fix the position between the connecting rod 29 and the slide plate 35, so that the vertical shaft 28 is connected to the slide plate 35. At this time, the eccentric wheel 11 is driven to rotate by the motor 1, so that the oscillation barrel 1 moves back and forth left and right. The long shaft 27 is manually rotated to rotate the connecting rod 29 to rotate the connecting rod 29 to the initial position, thereby releasing the connection with the slide plate 35, so that when another group of test tubes 38 are subsequently oscillated, each culture dish 9 will not be affected.

[0052] A working method of a single cell culture device, the specific steps are as follows:

[0053] Step 1: Transfer the cells to be cultured into the test tube 38, inject the culture solution and seal it, then clamp it into the placement slot 17 provided on the placement table 5. Similarly, clamp multiple test tubes 38 containing single cells and culture solution into other placement slots 17 in sequence;

[0054] Step 2: The connecting shaft 15 is driven to rotate by the second motor, thereby driving the central gear 39 to rotate, and driving each transmission gear 19 to rotate, and then driving the clamping plate 18 to rotate until its inner wall is close to the outer wall of the test tube 38, clamping and fixing the test tube 38, and clamping and fixing several other test tubes 38 at the same time;

[0055] Step 3: The eccentric wheel 11 is driven to rotate by the motor 1, so that the oscillation barrel 1 generates a lateral vibration force, and each test tube 38 is vibrated laterally. When the eccentric wheel 11 rotates, the bevel gear 26 rotates accordingly, driving the two bevel gears 1 23 to rotate, so that the turntable 34 rotates, and the connecting rod 1 24 and the connecting rod 2 25 are coordinated to make the placement table 5 move up and down reciprocatingly, generating a vertical vibration force, and vibrating each test tube 38 vertically. The test tube 38 is vibrated laterally and vertically at the same time, so that the cells and the culture solution are fully vibrated and fused;

[0056] Step 4: The connecting shaft 15 is driven to reverse by the motor 2 to release the clamping fixation of the test tube 38, and then the single cells after each oscillation and fusion are sequentially put into each culture dish 9, and the corresponding culture medium is added to transfer the single cells to the culture dish 9 for culture;

[0057] Step 5: The end of the connecting rod 29 away from the vertical axis 28 is engaged and fixed with the bottom of the slide 35, and then the eccentric wheel 11 is driven by the motor 1 to rotate, so that the oscillation barrel 1 moves back and forth, and the single cells and culture fluid in each culture dish 9 placed on the circular plate 1 8 are automatically oscillated left and right, and finally left to stand, completing the culture.

[0058] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
