Technical Field

[0001] The present invention relates to the technical field of stem cell culture, and in particular to a stem cell culture tank with an exchangeable cylinder body and a use method thereof. Background Art

[0002] Stem cells are a type of multipotent cell with the ability to self-replicate and differentiate. They can produce at least one type of highly differentiated daughter cells. Therefore, they have very high research value in medicine. In recent years, the scale of stem cell research and cultivation in my country has gradually expanded.

[0003] In the laboratory, an incubator is needed to culture stem cells. When culturing suspended stem cells, they need to be placed on an shaking table to facilitate the movement of the culture medium in the culture box to achieve the effect of liquid exchange and flow of the culture medium. The shaking table is then placed in the incubator. Since the existing shaking table is a single-layer setting, the number of cells that can be accommodated on the surface of the shaking table is small, and it also occupies a large space in the incubator. At the same time, for the preparation of some reagents used to culture stem cells, the reagents need to be restored to room temperature through a heating device such as a water bath and fully mixed. In subsequent steps, a centrifuge is required to separate the stem cells from the liquid and extract the stem cell clusters. There are too many types of instruments used and the cost is high. Summary of the invention

The end of the inclined shaft away from the hinged plate is hinged to the connecting seat. The cylinder 1 is fixedly installed on the lower surface of the upper cover, and the telescopic end of the cylinder 1 is fixedly installed with a mounting seat by bolts. The mounting seat is rotatably connected to the upper connecting seat, the rotating disk is fixedly connected to the lower connecting seat, and a culture containing assembly is provided on the eccentric rotating shaft.

[0007] In the above-mentioned stem cell culture tank with an interchangeable cylinder body, three equidistantly distributed positioning components are fixedly installed on the rotating shaft, and each of the three positioning components is composed of two positioning plates. The culture accommodating component includes three mounting disks. A mounting disk is rotatably arranged between the two positioning plates of any positioning component and on the rotating shaft. The mounting position of the mounting disk is biased in the direction of the oblique axis and the offset distance is the same as the distance when the oblique axis and the eccentric rotating axis are kept parallel. Two semi-circular half-slot boxes are inserted in the mounting disk, and a semi-circular make-way groove is provided on the side where the two half-slot boxes are close to each other.

[0008] In the above-mentioned stem cell culture tank with replaceable cylinder body, the outer walls of the two half-slot boxes in any installation plate are in conflict with the inner wall of the installation plate, and the two half-slot boxes in any installation plate are in conflict with each other.

[0010] In the above-mentioned stem cell culture tank with replaceable cylinder body, the upper part of the rotating disk is slidably connected with cylinder 2, and the telescopic end of cylinder 2 is fixedly connected with the eccentric rotating shaft.

[0011] In the above-mentioned stem cell culture tank with an interchangeable cylinder body, straight rods are fixedly installed on both sides of the upper clamping block, and the two straight rods are both in a three-section structure. Limit rods are fixedly installed on the sides of the two straight rods that are away from each other, and the limit rods pass over the installation rods.

[0012] In addition, the present invention also discloses a method for using a stem cell culture tank with an interchangeable cylinder, and the specific steps are as follows:

[0015] S3. Adjust the equipment again: when it is necessary to control the rotating parts to drive the culture container assembly to shake, control cylinder one and cylinder two to offset the eccentric rotating shaft by a specified distance, place the container to be shaken in the corresponding half-slot box, and control the speed of the motor to make the eccentric rotating shaft drive the half-slot box to shake; when centrifugation is required, control cylinder one to shrink to the minimum stroke and control cylinder two to reach the maximum stroke, so that the eccentric rotating shaft is parallel to the oblique axis, and then drive the installation box to centrifuge through the motor.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The rotating disk is driven by a motor to rotate, and the eccentric rotating mechanism is rotated as a whole through the rotating disk and the mounting seat. The fixing rod and the limit slider prevent the mounting disk from axially rotating around the eccentric rotating axis.

[0018] 2. The reagents can be fully mixed by shaking the mounting plate, and the reagents can be restored to room temperature through the temperature control device in the tank, reducing the cost of using laboratory equipment.

[0019] 3. The eccentric rotating axis is controlled to be parallel to the oblique axis by cylinders one and two, and the mounting rod is limited by the limit rod, so that the limit rod drives the mounting rod to rotate, and then the mounting plate rotates in the axial direction of the motor, which can centrifuge the reagents placed in the mounting groove, realize the three effects of shaking the culture solution in the suspended stem cells, mixing the experimental reagents and centrifuging, improve practicality, and further reduce the cost of stem cell culture in the laboratory.

The two connecting components 4 are respectively used to connect the cylinder 14 and the rotating disk 12. The two connecting components 4 include an inclined shaft 41, a hinged plate 42 and a connecting seat 43. One end of the hinged plate 42 is fixedly connected to the inclined shaft 41, and the other end of the hinged plate 42 is fixedly installed on the eccentric rotating shaft 13. The end of the inclined shaft 41 away from the hinged plate 42 is hinged to the connecting seat 43. The cylinder 14 is fixedly installed on the upper cover. 3, the telescopic end of the cylinder 14 is fixedly installed with a mounting seat 15 by bolts, the mounting seat 15 is rotatably connected to the upper connecting seat 43, the rotating disk 12 is fixedly connected to the lower connecting seat 43, the eccentric rotating shaft 13 is provided with a culture containing assembly, and the tank body 1 is provided with a temperature control device in the prior art to maintain the optimal culture temperature of the stem cells, the angle of the inclined axis 41 is controlled by the telescopic control of the cylinder 14 to make it parallel to the eccentric rotating shaft 13, and then the eccentric rotating shaft 13 is controlled to approach the inclined axis 41, the rotating disk 12 is driven to rotate by the motor 11, the eccentric rotating mechanism is rotated as a whole by the rotating disk 12 and the mounting seat 15, and the culture containing assembly is driven to shake with different amplitudes by different positions of the eccentric rotating shaft 13, so as to solve the problem that the existing oscillator needs to be placed in the incubator with limited size, and then, by the culture containing assembly, the problem that the platform of the oscillator can accommodate a small number of cells is solved, and at the same time, the reagent can be fully mixed by shaking the mounting disk 5, and the reagent is restored to room temperature by the temperature control device in the tank body 1, thereby reducing the use cost of laboratory equipment.

[0033] Three equidistantly distributed positioning components are fixedly installed on the rotating shaft, and each of the three positioning components is composed of two positioning plates 16. The culture containing component includes three mounting disks 5. A mounting disk 5 is rotatably arranged between the two positioning plates 16 of any positioning component and on the rotating shaft. The mounting position of the mounting disk 5 is biased toward the direction of the oblique axis 41 and the offset distance is the same as the distance when the oblique axis 41 and the eccentric rotating shaft 13 are kept parallel. Two semicircular half-slot boxes 51 are inserted in the mounting disk 5. A semicircular makeshift groove 52 is provided on one side of the two half-slot boxes 51 that are close to each other. Different mounting grooves are provided in the half-slot box 51, which can be used to place stem cell half-slot boxes 51, mixed reagents, test tubes and other containers, and the makeshift groove 52 is used to make way for the positioning component.

[0034] The outer walls of the two half-slot boxes 51 in any mounting plate 5 are in conflict with the inner wall of the mounting plate 5, and the two half-slot boxes 51 in any mounting plate 5 are in conflict with each other. The mutual conflict between the mounting plate 5 and the half-slot boxes 51 increases the stability of the half-slot boxes 51 during movement and avoids shaking due to gaps.

[0035] The mounting plates 5 are fixedly connected by two symmetrical mounting rods 53, and a movable plate 6 is fixedly installed on the top of the mounting rod 53. A sliding groove 61 is provided on the side wall of the limiting plate, and a limiting slide plate 62 slides in the sliding groove 61. A limiting groove 63 is provided on the slide plate. A fixing rod 64 is installed on the upper surface of the tank body 1, and the fixing rod 64 passes through the limiting groove 63. When the inclined axis 41 is in an inclined state, the eccentric rotating shaft 13 is driven to rotate by the motor 11. At this time, the fixing rod 64 and the limiting slide plate 62 are limited by the fixing rod 64 and the limiting groove 63, so that the fixing rod 64 and the limiting slide plate 62 are kept in a vertical state. Further, the limiting slide plate 62 slides in the sliding groove 61, so that the fixing rod 64 and the movable plate 6 are kept in a vertical state. Further, the movable plate 6 cannot rotate, and the eccentric rotating shaft 13 rotates. Under the connection action of the mounting rod 53, the mounting plate 5 cannot rotate around the eccentric rotating shaft 13. At this time, the rotation of the eccentric rotating shaft 13 only produces a shaking effect on the mounting plate 5.

[0036] The upper part of the rotating disk 12 is slidably connected with a second cylinder 17 , and the telescopic end of the second cylinder 17 is fixedly connected to the eccentric rotating shaft 13 .

[0037] A U-shaped block 44 is fixedly installed on the inclined shaft 41. The cylinder 14 contracts to drive the eccentric rotating shaft 13 to approach the inclined shaft 41 and make it parallel to the inclined shaft 41. The hinge plate 42 is also parallel, so that the eccentric rotating shaft 13 is inserted into the block 44, thereby increasing the stability of the inclined shaft 41 and the eccentric rotating shaft 13.

[0038] Straight rods 45 are fixedly installed on both sides of the upper clamping block 44, and the two straight rods 45 are of three-section structure. Limit rods 46 are fixedly installed on the sides of the two straight rods 45 away from each other, and the limit rods 46 pass over the mounting rods 53. When the eccentric rotating shaft 13 is parallel to the inclined shaft 41, since the mounting position of the mounting disk 5 is biased toward the direction of the inclined shaft 41 and the offset distance is the same as the distance when the inclined shaft 41 and the eccentric rotating shaft 13 remain parallel, at this time, the mounting disk 5 is coaxial with the output shaft of the motor 11. At the same time, the two limit rods 46 rotate synchronously at a specified angle under the rotation of the inclined shaft 41 and respectively conflict with the mounting rods 53, and the mounting disk 5 is driven to rotate by the motor 11, and the mounting rods 53 are driven to rotate under the action of the limit rods 46. Further, the mounting disk 5 and the half-slot box 51 in the mounting disk 5 are driven to rotate, so that the reagent placed in the mounting slot can be centrifuged, so as to achieve the three effects of shaking the culture solution in the suspended stem cells, mixing the experimental reagents and centrifuging, thereby improving practicality and further reducing the cost of stem cell culture in the laboratory.

[0039] In addition, the present invention also discloses a method for using a stem cell culture tank with an interchangeable cylinder, and the specific steps are as follows:

[0040] S1, installing the equipment: placing the upper cover 3 on the culture cylinder body 2, adjusting the telescopic length of the cylinder 1 14 and the cylinder 2 17, matching the upper mounting seat 15 with the connecting seat 43 and connecting them, placing the half-slot box 51, after installation, placing the culture cylinder body 2 into the tank body 1, and rotating the culture cylinder body 2 until the output shaft of the motor 11 is inserted into the rotating disk 12;

[0041] S2. Preliminary equipment adjustment: control the cylinder 1 14 and the cylinder 2 17 to extend, push the eccentric rotating shaft 13 to deviate a specified distance, and prevent the limit slider from contacting the fixed rod 64 during the rotation of the eccentric rotating mechanism; control the motor 11 to rotate so that the fixed rod 64 is aligned with the limit groove 63; control the cylinder 14 to retract a specified distance so that the fixed rod 64 is inserted into the limit groove 63;

[0042] S3. Adjust the equipment again: when it is necessary to control the rotating parts to drive the culture container assembly to shake, control cylinder 1 14 and cylinder 2 17 to offset the eccentric rotating shaft 13 by a specified distance, place the container to be shaken in the corresponding half-slot box 51, and control the rotation speed of the motor 11 to make the eccentric rotating shaft 13 drive the half-slot box 51 to shake; when centrifugation is required, control cylinder 14 to shrink to the minimum stroke and control cylinder 2 17 to reach the maximum stroke, so that the eccentric rotating shaft 13 is parallel to the inclined axis 41, and then drive the installation box to centrifuge through the motor 11.

[0043] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
