[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1-5 This utility model provides a cell climbing device.
[0030] Example 1
[0031] A cell climbing device includes a culture dish 10, a sealing ring 20, a cell climbing sheet 30, and a base 40 arranged sequentially from top to bottom.
[0032] The culture dish 10 has a hollow through-hole structure. The culture dish 10 includes an upper section 11 and a lower section 12. The upper section 11 and the lower section 12 are coaxially arranged. The cross-sectional area of the upper section 11 is a, and the cross-sectional area of the lower section 12 is b, satisfying the quantitative relationship: a < b.
[0033] The petri dish 10 is detachably connected to the base 40 via the lower section 12 of the petri dish.
[0034] The operation process achieved by existing devices and their auxiliary devices is relatively complex and prone to contamination.
[0035] In this embodiment of the present invention, a cell climbing device is provided, which can overcome the two disadvantages mentioned above, enabling cells to be cultured directly on the climbing sheet, and allowing the climbing sheet to be quickly removed for subsequent experiments after culture.
[0036] The specific working principle is as follows:
[0037] Assembly of S1 base 40 and petri dish 10
[0038] S11 Invert the culture dish 10 and place the sealing ring 20 and cell climbing sheet 30 in sequence;
[0039] S12 connects and fixes the base 40 to the petri dish 10;
[0040] S2 adds the cells to be cultured and the culture medium to the cell crawling slide 30 to complete the cell culture.
[0041] After S3 has been cultured, remove the excess liquid culture medium, unscrew culture dish 10, take out cell smear 30, and then proceed with subsequent experiments.
[0042] In this embodiment, since the culture dish 10 has a hollow through-structure, the cell growth status can be observed at any time during cell culture.
[0043] Example 2
[0044] In this embodiment:
[0045] The petri dish 10 is an axially penetrating hollow stepped cylinder, consisting of two coaxial cylinders, cylinder one and cylinder two.
[0046] The upper cylinder has a smaller diameter than the lower cylinder, and the two cylinders are connected by a radially abrupt transition surface to form a stepped transition, while the overall axial direction remains a continuous channel.
[0047] The structure of the more specific petri dish 10 is as follows:
[0048] Main body shape: It adopts a coaxial double cylindrical superimposed structure with a continuous central through hole in the axial direction;
[0049] Dimensional characteristics: Diameter D1 of the upper cylinder < Diameter D2 of the lower cylinder; Transition form: The joint surface of the upper and lower cylinders is abruptly connected in a vertical step shape;
[0050] Structural characteristics: There is a continuous cavity running through the entire structure along the axial direction.
[0051] In this embodiment, the specific operation steps can be referred to in Embodiment 1. The above-mentioned structural design makes the operation convenient and effectively prevents pollution.
[0052] Example 3
[0053] In this embodiment:
[0054] The petri dish 10 is detachably connected to the base 40 via the lower section 12 of the petri dish through threads.
[0055] In specific operation, in this embodiment:
[0056] The culture dish 10 has a hollow cylindrical structure. The upper part can be regarded as an ordinary culture dish, which is the cell culture functional area, while the inner side of the lower part has a screw-on cap.
[0057] The sealing ring 20 is inserted from under the culture dish 10, its diameter matching the central step of the dish, thus securing it. Next, the cell spreader 30 is inserted from under the dish 10; the sealing ring 20, through its interference fit at the edge, holds the cell spreader 30 in place. The base 40, also a hollow cylinder with threads, is screwed into the lower threaded portion of the culture dish 10, applying pressure to the sealing ring 20 and the cell spreader 30 to ensure a complete seal. The entire device is hollow, allowing for continuous observation of cell growth during culture.
[0058] The specific working principle is as follows: After assembly, it can be used directly. The cells to be prepared into a cell slide are directly transferred into the device and an appropriate amount of culture medium is added. After the culture is completed, the culture medium is aspirated, the screw is unscrewed and the cell slide is taken out, and then subsequent experiments are carried out.
[0059] Example 4
[0060] In this embodiment, the sealing ring 20 is made of silicone.
[0061] The choice of silicone material as the material for sealing ring 20 has the following advantages:
[0062] High elastic recovery rate: small permanent compression deformation and excellent sealing durability.
[0063] Low surface viscosity: Low coefficient of friction during dynamic sealing, suitable for sealing rotating shafts or reciprocating motion.
[0064] Electrical insulation: High resistivity
[0065] No plasticizer migration: No harmful substances are released during long-term use, avoiding media contamination.
[0066] In summary, the structures in embodiments 1 to 4 of this utility model have the following beneficial effects:
[0067] 1) Compared with the complex operations of fixing cell smears before use and removing them after use in the prior art, this invention optimizes these two steps, reducing experimental steps, saving time and reducing the risk of contamination.
[0068] 2) The device can be used multiple times; only the cell slides need to be replaced, and the rest can withstand autoclaving.
[0069] 3) The cell adhesion slide is made of high borosilicate glass and has undergone surface treatment, which makes it easier for cells to adhere to the wall.
[0070] 4) Cell slides do not require fixation before use, making them easier to remove;
[0071] 5) The compression force of the silicone ring and the threaded structure ensures the seal between the cell slide and the culture dish, so that the entire device is hollow while ensuring the sealing performance. The hollow feature allows for observation of cell growth status through a microscope at any time during use.
[0072] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
