Description

Technical Field

[0001] This utility model relates to the field of cell culture experimental equipment technology, specifically a cell culture centrifuge tube. Background Technology

[0002] In life science research, biopharmaceuticals, and other fields, cell culture is a fundamental and crucial experimental procedure, and cell culture centrifuge tubes, as commonly used experimental equipment, have a significant impact on experimental results. Currently, commercially available cell culture centrifuge tubes are generally made of polymer materials such as polypropylene (PP). These materials have good chemical stability and corrosion resistance, and can meet the chemical compatibility requirements of general cell culture processes.

[0003] Chinese Patent Announcement No. CN 208857309 U provides a cell culture centrifuge tube, including a tube body and a sealing cap connected to the tube body. The sealing cap has an opening on its top wall, and a soft plug is embedded in the opening. The soft plug includes a lower circular pad extending to the lower surface of the top wall. The lower circular pad is pressed against the open end face of the tube body when the sealing cap is closed. By adopting a soft plug structure that can abut against the opening of the tube body, the sealing performance is further improved compared with the prior art.

[0004] In existing technologies, cell culture centrifuge tubes rely solely on needles to pierce soft stoppers during cell inoculation and other operations. Frequent needle piercing of the soft stopper demands a high level of skill and expertise from the operator. Novice operators are prone to errors such as incorrect piercing angles and improper force control, and repeated piercing can also cause wear on the soft stopper, affecting its sealing performance. From an operational efficiency perspective, each inoculation requires a separate needle, making batch and rapid operations impossible. Compared to centrifuge tubes with convenient feeding mechanisms, the operation time increases exponentially when processing large numbers of cell samples. Therefore, we propose an improvement to this technology: a cell culture centrifuge tube. Utility Model Content

[0005] The purpose of this invention is to address the limitations of current cell culture centrifuge tube operation methods, such as the lack of convenient feeding design, reliance on needle plugging for inoculation, and the failure to optimize the experimental process, resulting in low experimental efficiency and high time and labor costs.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A cell culture centrifuge tube, through the linkage design of a baffle, side plate, guide rod and reset spring, realizes convenient opening and closing of the feed inlet, and the operation is simple and smooth. It can effectively reduce the chance of contamination and reduce time and effort costs, thereby improving the above-mentioned problems.

[0030] Example 1: Please refer to the appendix of the instruction manual. Figure 1-4 A cell culture centrifuge tube includes an outer tube 1, a cap 2 at the top of the outer tube 1, the outer tube 1 and the cap 2 being threadedly connected, a protective plate 3 at the top of the cap 2, a stop 9 slidably connected to the top of the cap 2, a rubber pad embedded at the bottom of the stop 9, side plates 10 fixedly installed on opposite sides of the stop 9, both side plates 10 being inserted into the cap 2 and slidably connected thereto, guide rods 12 being provided inside both side plates 10, the two guide rods 12 passing through the two side plates 10 respectively and slidably connected thereto, and multiple return springs 11 fixedly installed on one side of the stop 9, the ends of the multiple return springs 11 away from the cap 2 being fixedly connected to the cap 2.

[0031] In this embodiment of the utility model, the push plate 14 drives the stop block 9 to slide through the connecting rod 13. When it is necessary to open the feed port 8, the push plate 14 is pushed, the reset spring 11 is compressed, and the stop block 9 leaves the feed port 8. When the push plate 14 is released, the reset spring 11 is reset, and the stop block 9 is driven to close the feed port 8 again.

[0032] In this embodiment of the invention, by adopting a multi-seal design, the cell culture samples are effectively prevented from coming into contact with the external environment during storage, transportation and centrifugation, thus avoiding sample contamination, ensuring the accuracy and reliability of cell culture experiments, and reducing the risk of experimental failure.

[0033] Example 2: Please refer to the appendix of the instruction manual. Figure 1-4 In a preferred embodiment of the present invention, a conical block 7 is fixedly installed at the bottom of the pipe cover 2, and both the pipe cover 2 and the conical block 7 are provided with a connected feed inlet 8. The stop block 9 is slidably connected to the feed inlet 8.

[0034] The inner tube 4 of the cell culture centrifuge tube is fixedly installed inside the outer tube 1, and the inner tube 5 of the protective layer is fixedly installed inside the tube cap 2. The conical block 7 is slidably connected to the inner tube 5 of the protective layer.

[0035] A U-shaped insert plate 15 is fixedly installed at the bottom of the protective plate 3. A groove that mates with the U-shaped insert plate 15 is opened at the top of the protective plate 3. A rubber pad is fixedly installed at the top of the protective plate 3 and inside the groove. A card slot 16 is opened on the protective plate 3. The protective plate 3 is made of transparent plastic material.

[0036] A push plate 14 is slidably connected to the top of the pipe cover 2. A connecting rod 13 is fixedly installed on the side of the push plate 14 near the stop block 9 and on the corresponding sides of the feed inlet 8. Both ends of the two connecting rods 13 are fixedly connected to the stop block 9 and the push plate 14, respectively.

[0037] The outer tube 1 of the cell culture centrifuge tube is printed with graduation lines, and the junction of the tube cap 2 with the outer tube 1 of the cell culture centrifuge tube, the inner tube 5 of the protective layer and the block 9 is inlaid with a sealing ring.

[0038] In this embodiment of the invention, the conical block 7 at the bottom of the tube cap 2 slides in conjunction with the inner tube 5 of the protective layer. During feeding, the sample can smoothly enter the centrifuge tube through the feed inlet 8 and the conical block 7. The conical structure helps to guide the sample flow and reduce sample residue.

[0039] The reinforcing layer middle tube 4 and the protective layer inner tube 5 are made of high-strength materials. During centrifugation, they can withstand the centrifugal force generated by high-speed rotation, share the pressure on the outer tube 1 and the cap 2 of the cell culture centrifuge tube, and prevent the centrifuge tube from breaking due to excessive force. The reinforced structural design improves the overall strength and stability of the centrifuge tube, extends the service life of the centrifuge tube, reduces sample loss and experimental accidents caused by centrifuge tube breakage, ensures the safety of experimental personnel, and also reduces experimental costs.

[0040] The protective plate 3 is made of transparent plastic. The U-shaped insert 15 at the bottom can be inserted into the groove at the top of the tube cap 2 to achieve splicing, further protecting the top of the tube cap 2 from dust. The card slot 16 on the protective plate 3 can be used to insert cards labeled with sample information, such as cell type, culture time, and experiment number. The transparent protective plate 3 can protect the card information from damage and make it convenient for experimental personnel to quickly view the sample information.

[0041] In this embodiment of the utility model, the tube cap 2 is connected to the outer tube 1 of the cell culture centrifuge tube by a thread, and a sealing ring is embedded at the junction of the tube cap 2 with the outer tube 1 of the cell culture centrifuge tube, the inner tube 5 of the protective layer and the block 9.

[0042] When the rotating tube cap 2 is tightened, the threaded structure provides a tightening force, and the sealing ring fills the gap under compression to form a sealed space; the rubber pad embedded at the bottom of the stop block 9 can fit tightly against the surface of the tube cap 2 when it slides to the feed inlet 8, further sealing the feed inlet 8.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
