Description

Technical Field

[0001] This utility model relates to the field of biological experimental technology, and in particular to a culture dish support. Background Technology

[0002] Cell slurry pipetting is a technique used in cell experiments, primarily for separating cells from the surface of culture containers or for dispersing cells evenly in a liquid. Currently, in laboratories, cell slurry pipetting typically requires the operator to hold a culture dish in one hand and a pipette in the other. The operator uses the pipette to extract the cell slurry from the culture dish and then pipettes it back into the dish to complete the process. This process increases the operator's workload by requiring them to hold the culture dish continuously and also carries the potential risk of spillage due to improper operation. Utility Model Content

[0003] The purpose of this invention is to provide a culture dish support to solve the problem of inconvenience for workers when performing pipetting operations on cell fluid in the prior art.

[0004] To achieve the above objectives, embodiments of this application provide a petri dish support, comprising:

[0005] Base;

[0006] A support plate having a first end and a second end disposed opposite to each other, the second end being rotatably mounted on the base;

[0007] A placement plate is rotatably mounted on the support plate, and the rotation axis of the placement plate is perpendicular to the plane of the support plate. The placement plate has a placement groove for placing a petri dish.

[0008] An angle adjustment component is disposed between the support plate and the base, and the angle adjustment component is used to adjust the angle of the support plate relative to the base.

[0009] In some embodiments of this application, the culture dish support further includes a bearing, the outer ring of which is fixedly connected to the support plate, and the inner ring of which is fixedly connected to the placement plate.

[0010] In some embodiments of this application, the placement plate includes a first plate and a second plate that are fitted together; the first plate is connected to the inner ring of the bearing.

[0011] The first plate has a through hole coaxial with the bearing, and the second plate has a cavity passing through the through hole, which constitutes the placement groove.

[0012] In some embodiments of this application, the culture dish support further includes a clamping member for clamping and fixing the second plate to the first plate.

[0013] In some embodiments of this application, multiple clamping members are provided, and the multiple clamping members are spaced apart around the axial center line of the through hole.

[0014] In some embodiments of this application, the clamping includes a clamping plate, the clamping plate having a clamping cavity, and the clamping cavity having a first clamping wall and a second clamping wall disposed opposite to each other;

[0015] The first plate and the second plate are at least partially clamped in the clamping cavity at one end away from the axial center line of the through hole, such that the first clamping wall abuts against one of the first plate and the second plate, and the second clamping wall abuts against the other.

[0016] In some embodiments of this application, the angle adjusting member includes an adjusting plate, which has a rotating end and a snap-fit ​​end along the length extension direction of the adjusting plate, and the rotating end is rotatably connected to the first end.

[0017] The base has a snap-fit ​​component for engaging with the snap-fit ​​end.

[0018] In some embodiments of this application, the snap-fit ​​component includes a plurality of snap-fit ​​slots disposed on the base, and each snap-fit ​​slot is spaced apart along the rotation direction of the adjustment plate.

[0019] In some embodiments of this application, a mounting hole is provided through the support plate along its thickness direction, the bearing is disposed in the mounting hole, and the outer ring of the bearing is connected to the wall of the mounting hole.

[0020] In some embodiments of this application, the inner wall of the cavity is provided with an anti-slip rubber pad.

[0021] Compared with the prior art, the culture dish support of this embodiment of the utility model has the following advantages: This solution, by setting up a support plate, a placement plate, a base, and an angle adjustment component, allows the angle of the support plate relative to the base to be adjusted. The culture dish is placed in the placement groove on the placement plate, thus maintaining the culture dish at the required tilt angle for the experiment. This eliminates the need for the experimenter to hold the culture dish with one hand and perform cell slurry agitation, reducing the workload of the experimenter and avoiding the risk of cell slurry spillage due to instability in the experimenter's hand position. Furthermore, the placement plate in this solution is rotatably mounted on the support plate. During cell slurry agitation, the experimenter can drive the placement plate to rotate relative to the support plate, further improving the agitation effect. Attached Figure Description

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "front," "rear," "top," and "bottom," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as an obstruction of this utility model. It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0037] like Figures 1-8 As shown in the figure, this application provides a petri dish support, including a base 1, a support plate 2, a placement plate 3, and an angle adjustment component; the support plate 2 has a first end and a second end arranged opposite to each other, the second end of the support plate 2 is rotatably mounted on the base 1, and the placement plate 3 is rotatably disposed on the support plate 2, and the rotation axis of the placement plate 3 is perpendicular to the plane where the support plate 2 is located, as shown in the figure. Figure 1 As shown, the placement plate 3 has a placement groove for placing petri dishes. The size of the placement groove is set according to the size specifications of the petri dishes, so that the inner diameter of the placement groove matches the outer diameter of the petri dishes. An angle adjustment component is located between the support plate 2 and the base 1. The experimenter can use the angle adjustment component to adjust the tilt angle of the support plate 2 relative to the base 1, thereby adjusting the tilt angle of the petri dishes.

[0038] In this embodiment, the experimenter places the culture dish containing cell solution in the placement tank, and then adjusts the tilt angle of the support plate 2 relative to the base 1 using the angle adjustment device, so that the culture dish is kept at a suitable tilt angle. The reason for keeping the culture dish at a tilt angle is that: the amount of cell solution in the culture dish is relatively small, and tilting the culture dish at a certain angle (so that the small amount of cell solution in the culture dish gathers together) helps the experimenter to aspirate the small amount of cell solution in the culture dish with a pipette, and then return the aspirated cell solution to the culture dish after aspiration, thereby completing the cell solution aspiration operation. Since the experimenter no longer needs to hold the culture dish to aspirate, the risk of cell solution spilling out of the culture dish due to improper operation or lack of stability is reduced. While performing the above process, the placement plate 3 is driven to rotate continuously relative to the support plate 2, which causes the culture dish to rotate synchronously while it is tilted, further improving the aspiration effect of the cell solution.

[0039] In some embodiments of this application, such as Figure 5, Figure 6 As shown, the petri dish support also includes a bearing 6, which includes an outer ring, an inner ring, and a rolling element (ball) located between the outer ring and the inner ring. The outer ring of the bearing 6 is fixedly connected to the support plate 2, and the inner ring of the bearing 6 is fixedly connected to the placement plate 3. The bearing 6 in this design makes it easier for the placement plate 3 to rotate relative to the support plate 2, allowing the experimenter to drive the placement plate 3 to rotate relative to the support plate 2 with a smaller driving force.

[0040] In some embodiments of this application, such as Figure 2 As shown, the placement plate 3 includes a first plate 31 and a second plate 32 that are fitted together, as... Figure 5 , Figure 6 As shown, the first plate 31 is connected to the inner ring of the bearing 6, and a through hole 311 coaxially arranged with the bearing 6 is provided on the first plate 31. Figure 5 , Figure 6 As shown, the second plate 32 has a cavity 321 that passes through the perforation 311. The cavity 321 forms a placement groove. When performing cell blowing operations, the culture dish can be placed in the cavity 321.

[0041] In this design, the second plate 32 can be configured with cavities 321 of different sizes according to the size specifications of the culture dish, so that the inner diameter of the cavity 321 matches the outer diameter of the culture dish of different sizes. When performing cell fluid refluxing, the second plate 32 is selected according to the size specifications of the culture dish containing the cell fluid, so that when the culture dish is placed in the cavity 321, it can be properly secured in the cavity 321, preventing the culture dish from rotating relative to the cavity 321 as the placement plate 3 rotates. At the same time, the perforation 311 on the first plate 31 should be set as large as possible to accommodate culture dishes with larger outer diameters.

[0042] In some embodiments of this application, such as Figure 1 , Figure 7 As shown, the petri dish support also includes a clamping member 5, which is used to clamp and fix the second plate 32 to the first plate 31, and to prevent relative movement of the second plate 32 relative to the first plate 31; Figure 4 , Figure 5 As shown, an annular component is provided between the first plate 31 and the bearing 6. One end of the annular component is connected to the first plate 31, and the other end is connected to the inner ring of the bearing 6 (the annular component is not labeled in the figure). The annular component ensures that a certain distance is maintained between the first plate 31 and the support plate 2 (e.g., ...). Figure 4 As shown), this allows experimenters to disassemble and assemble the clamping part 5 to replace different second plates 32.

[0043] In some embodiments of this application, such as Figure 1 As shown, in this scheme, there are multiple clamping members 5. The multiple clamping members 5 are arranged at intervals around the axial center line of the through hole 311. The arrangement of multiple clamping members 5 improves the fixing effect of the second plate 32 and improves the connection stability between the second plate 32 and the first plate 31.

[0044] In some embodiments of this application, such as Figure 8 As shown, the clamping device includes a clamping plate 51, which has a clamping cavity 52. ​​The clamping cavity 52 has a first clamping wall 521 and a second clamping wall that are disposed opposite to each other. At least one end of the first plate 31 and the second plate 32 away from the axial center line of the through hole 311 is clamped in the clamping cavity 52, such that the first clamping wall 521 abuts against one of the first plate 31 and the second plate 32, and the second clamping wall 522 abuts against the other.

[0045] The clamping member 5 in this solution can be made of a material with a certain degree of elasticity (such as rubber or plastic). The distance between the first clamping wall 521 and the second clamping wall 522 can be slightly less than the sum of the thicknesses of the first plate 31 and the second plate 32 at their peripheral positions. Figure 7 As shown, when the outer peripheral portions of the first plate 31 and the second plate 32 are clamped in the clamping cavity 52, the first plate 31 and the second plate 32 are tightly fitted together under the clamping force applied by the clamping plate 51, achieving a stable connection between the first plate 31 and the second plate 32. When it is necessary to replace the second plate 32, the clamping plate 51 can be directly removed from the first plate 31 and the second plate 32.

[0046] In some embodiments of this application, such as Figure 3 As shown, the angle adjusting component includes an adjusting plate 4, which has a rotating end 41 and a snap-fit ​​end 42 along the length of the adjusting plate 4. The rotating end 41 is rotatably connected to the first end.

[0047] The base 1 has a snap-fit ​​component for engaging with the snap-fit ​​end 42. During cell fluid blowing, the experimenter rotates the support plate 2 to the required tilt angle according to the experimental needs, and then engages the snap-fit ​​end 42 with the snap-fit ​​component on the base 1. Thus, by cooperating with the adjustment plate 4 and the snap-fit ​​component on the base 1, the support plate 2 can be maintained at the adjusted tilt angle.

[0048] In some embodiments of this application, such as Figure 1 , Figure 3As shown, the snap-fit ​​component includes multiple snap-fit ​​slots 11 on the base 1. Each snap-fit ​​slot 11 is spaced apart along the rotation direction of the adjusting plate 4. By inserting the snap-fit ​​end 42 of the adjusting plate 4 into different snap-fit ​​slots 11, the support plate 2 can be maintained and positioned at different tilt angles. Preferably, in this solution, multiple adjusting plates 4 can be provided (the base 1 is provided with corresponding snap-fit ​​slots 11 that match the adjusting plates 4), and the multiple adjusting plates 4 are spaced apart to further improve the support stability of the support plate 2.

[0049] In some embodiments of this application, such as Figure 5 , Figure 6 As shown, a mounting hole 21 is provided through the support plate 2 along the thickness direction, the bearing 6 is disposed in the mounting hole 21, and the outer ring of the bearing 6 is connected to the wall of the mounting hole 21.

[0050] In some embodiments of this application, such as Figure 7 As shown, in order to further improve the positioning effect of the culture dish placed in the placement tank, an anti-slip rubber pad 7 can be provided on the inner wall of the cavity 321. When the culture dish is placed in the placement tank, the outer wall of the culture dish is squeezed by the anti-slip rubber pad 7, so that it can be stably placed in the placement tank, ensuring the stability of the culture dish when the placement plate 3 rotates relative to the support plate 2.

[0051] The working process of this utility model is as follows: The experimenter selects a matching second plate 32 according to the size of the culture dish containing the cell solution, and then clamps and fixes the second plate 32 on the first plate 31 using the clamping member 5; then, the angle adjustment member is adjusted to adjust the tilt angle between the support plate 2 and the base 1 to the position required for the experiment; then the culture dish containing the cell solution is placed in the placement groove; the experimenter holds a pipette in one hand and drives the placement plate 3 to rotate relative to the support plate 2 at a certain speed with the other hand, thereby completing the process of pipetting the cell solution.

[0052] In summary, this utility model embodiment provides a culture dish support. This solution, by setting up a support plate 2, a placement plate 3, a base 1, and an angle adjustment component, allows the angle of the support plate 2 relative to the base 1 to be adjusted. The culture dish is placed in the placement groove on the placement plate 3, thus maintaining the culture dish at the required tilt angle for the experiment. This eliminates the need for the experimenter to hold the culture dish with one hand and perform cell slurry agitation, reducing the experimenter's workload and avoiding cell slurry spillage due to instability caused by the experimenter holding the culture dish. Furthermore, the placement plate 3 is rotatably mounted on the support plate 2. During cell slurry agitation, the experimenter can drive the placement plate 3 to rotate relative to the support plate 2, further improving the agitation effect.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
