Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological experimental equipment technology, and in particular to a rotating cell culture device. Background Technology
[0002] The Synthecon Rotating Cell Culture System (RCCS) is an advanced cell culture device that simulates a microgravity environment and is widely used in basic medicine, drug development, regenerative medicine, and other fields. The RCCS keeps cells suspended in the culture medium by rotating the culture tube. Under the combined effects of rotational tangential force and gravity, the cells form a three-dimensional spherical structure. This culture method avoids the cell flattening phenomenon found in traditional two-dimensional culture and more closely resembles the in vivo cell growth environment. Simultaneously, the system is equipped with a silica gel oxygenation membrane that allows for gas exchange, ensuring that cells receive sufficient oxygen and remove metabolic waste.
[0003] In existing rotating cell culture devices, the connection between the culture tube and the rotating base is achieved via a stud and threaded hole. Specifically, a stud is located at the center of the rotating base, and a threaded hole is located at the center of the end face of the culture tube where it intersects with the rotating base. When installing the culture tube onto the rotating base, the culture tube needs to be rotated multiple times to engage the stud and threaded hole, which is cumbersome. Furthermore, because the rotating base is rotatable, it tends to rotate along with the culture tube during installation, making it difficult to engage the stud and threaded hole properly, thus complicating the installation process.
[0004] In addition, in existing devices, when multiple rotating bases need to be set up, each rotating base is controlled by a separate motor, resulting in a large number of motors required in the entire device, which can easily lead to a large device size. Utility Model Content
[0005] The main objective of this invention is to provide a rotating cell culture device to solve the aforementioned technical problems.
[0006] To achieve the above objectives, this utility model proposes a rotating cell culture device, including a drive box, culture tubes, and multiple rotating bases rotatably mounted on the front upright plate of the drive box; a drive mechanism is provided inside the drive box to drive the rotating bases to rotate; a first magnetic ring is embedded on the front end face of the rotating base; a second magnetic ring is embedded on the rear end face of the culture tube; when the rear end face of the culture tube is in contact with the front end face of the rotating base, the first magnetic ring and the second magnetic ring attract each other.
[0007] Preferably, a positioning countersunk hole is provided at the center of the rear end face of the culture tube; a centering post for interlocking with the positioning countersunk hole is provided at the center of the front end face of the rotating base.
[0008] Preferably, a hemispherical head is provided at the end of the centering column away from the rotating base.
[0009] Preferably, a plurality of slots are evenly distributed in a ring at the edge of the rear end face of the culture tube; and a plurality of blocks for engaging with the slots are evenly distributed in a ring at the edge of the front end face of the rotating base.
[0010] Preferably, the rotating base is mounted on the front plate of the drive box via a rotating shaft; the drive mechanism includes a drive motor, a driving gear, and multiple driven gears; the rotating base is fixedly mounted on the front end of the rotating shaft; a driven gear is fastened to the rear end of each rotating shaft; the driving gear is fixedly mounted on the output shaft of the drive motor; all driven gears mesh with the driving gear.
[0011] Preferably, a support beam is erected between the left and right upright plates of the drive box; the drive motor is mounted on the support beam.
[0012] Preferably, a base plate is provided at the bottom of the drive box, and the front end of the base plate extends forward to form a cantilever end.
[0013] Preferably, the drive box includes a removable top cover and a rear upright.
[0014] Preferably, the number of rotating bases is four.
[0015] Preferably, four slots are provided in each culture tube, and four blocks are provided on each rotating base, with the four blocks integrally formed on the front end surface of the rotating base.
[0016] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:
[0017] (1) In this utility model, by embedding a first magnetic ring on the front end face of the rotating base and a second magnetic ring on the rear end face of the culture tube, when the culture tube needs to be installed on the rotating base, it is only necessary to connect the rear end face of the culture tube with the rotating base, and the culture tube can be installed on the rotating base by using the mutual attraction of the first magnetic ring and the second magnetic ring. The operation is simple and quick, overcoming the cumbersome operation problem that exists when using studs and threaded holes for connection in the prior art.
[0018] (2) In this utility model, by setting a positioning countersunk hole at the center of the rear end face of the culture tube and setting a centering column at the center of the front end face of the rotating base for fitting with the positioning countersunk hole, when the culture tube is installed on the rotating base, the structure of the positioning countersunk hole and the centering column working together helps to ensure that the axis of the culture tube coincides with the axis of the rotating base. When the rotating base drives the culture tube to rotate together, the unbalanced force can be reduced.
[0019] (3) In this utility model, by using the slot on the rear end face of the culture tube to cooperate with the block on the front end face of the rotating base, the rotating base can better drive the culture tube to rotate, and avoid the two from slipping against each other.
[0020] (4) In this utility model, the drive mechanism uses a method of meshing one driving gear with multiple driven gears for transmission. Only one drive motor needs to be connected to the driving gear, which helps to simplify the structure of the drive device, making the drive mechanism more compact and reducing the size of the device.

[0031] As shown in the accompanying drawings, a rotating cell culture device includes a drive box 2, a culture tube 4, and a plurality of rotating bases 3 rotatably mounted on the front upright plate of the drive box 2. A drive mechanism is provided inside the drive box 2 to drive the rotating bases 3 to rotate. A first magnetic ring 5 is embedded on the front end face of the rotating base 3. A second magnetic ring 6 is embedded on the rear end face of the culture tube 4. When the rear end face of the culture tube 4 is in contact with the front end face of the rotating base 3, the first magnetic ring 5 and the second magnetic ring 6 attract each other.
[0032] By adopting the above structure, when it is necessary to install the culture tube 4 on the rotating base 3, it is only necessary to connect the rear end face of the culture tube 4 with the rotating base 3, and use the first magnetic ring 5 and the second magnetic ring 6 to attract each other to install the culture tube 4 on the rotating base 4. The operation is simple and quick.
[0033] In this embodiment, a positioning countersunk hole 4a is provided at the center of the rear end face of the culture tube 4; a centering post 3a for interlocking with the positioning countersunk hole 4a is provided at the center of the front end face of the rotating base 3. When the culture tube 4 is mounted on the rotating base 3, the interlocking structure of the positioning countersunk hole 4a and the centering post 3a helps to ensure that the axis of the culture tube 4 coincides with the axis of the rotating base 3. When the rotating base 3 drives the culture tube 4 to rotate together, the unbalanced force can be reduced. To facilitate the insertion of the centering post 3a into the positioning countersunk hole 4a, the end of the centering post 3a away from the rotating base 3 is set as a hemispherical head 3c, which serves as a guide.
[0034] In this embodiment, multiple slots 4b are evenly distributed in a ring at the edge of the rear end face of the culture tube 4; multiple locking blocks 3b are evenly distributed in a ring at the edge of the front end face of the rotating base 3 for engaging with the slots 4b. This allows the rotating base 3 to better drive the culture tube 4 to rotate, preventing slippage between them. Specifically, four slots 4b are provided on each culture tube 4, and four locking blocks 3b are provided on each rotating base 3, with the four locking blocks 3b integrally formed on the front end face of the rotating base 3.
[0035] In this embodiment, the rotating base 3 is mounted on the front plate of the drive box 2 via a rotating shaft 7. A bearing (not shown in the figure) is provided between the front plate of the drive box 2 and the rotating shaft 7. Using a bearing to mount the rotating shaft 7 is a conventional technical means, and will not be described in detail here.
[0036] The drive mechanism inside the drive housing 2 includes a drive motor 8, a driving gear 9, and four driven gears 10. Specifically, a rotating base 3 is fixedly mounted on the front end of the rotating shaft 7. In this embodiment, there are four rotating bases 3, each corresponding to one rotating shaft 7, with the rear ends of all four rotating shafts 7 extending into the drive housing 2. A driven gear 10 is fastened to the rear end of each rotating shaft 7, for a total of four driven gears 10. The driving gear 9 is fixedly mounted on the output shaft of the drive motor 8; all four driven gears 10 mesh with the driving gear 9. By employing the above-described drive mechanism, the drive motor 8 drives the driving gear 9 to rotate, thereby synchronously driving the four driven gears 10 to rotate, thus causing the four rotating bases 3 to rotate simultaneously.
[0037] Combination Figure 2As shown, a support beam 11 is erected between the left and right upright plates of the drive box 2; the drive motor 8 is mounted on the support beam 11.
[0038] In this embodiment, a base plate 1 is provided at the bottom of the drive box 2, and the front end of the base plate 1 extends forward to form a cantilever end. By using the base plate 1, the drive box 2 can be prevented from tilting.
[0039] To facilitate the maintenance of the drive mechanism inside the drive box 2, the top cover plate 2a and the rear upright plate 2b of the drive box 2 are designed as detachable structures. Specifically, the top cover plate 2a and the rear upright plate 2b are respectively installed on the main body of the drive box 2 with screws. When disassembly is required, the screws can be loosened for disassembly.
