Description

Technical Field

[0001] This utility model relates to the field of cell cryopreservation tube technology, specifically to a cell cryopreservation tube and its cap placement tray. Background Technology

[0002] Cell cryopreservation is a technique that allows cells to be preserved for a long period of time by placing them in a low-temperature environment to slow down their metabolic activity. To avoid contamination, this process is usually performed in a cleanroom that meets Class 10,000 standards and follows strict aseptic operating procedures.

[0003] When performing cell cryopreservation, operators need to fully open the cryovials. To avoid contamination risks, the opened cryovial caps should be placed horizontally on their sides, avoiding placing them face up or down. However, in current practice, cryovial caps are usually placed directly on the worktable. When processing multiple cryovials in batches, the caps are required to be arranged sequentially according to the order of the cryovials, ensuring that each cap accurately matches its corresponding cryovial. This traditional placement method has significant drawbacks in actual operation: operators can easily accidentally touch the caps, causing misalignment and increasing the possibility of cross-contamination between cells. Furthermore, leaving the caps open upwards for extended periods makes them susceptible to microbial contamination, increasing the risk of contamination during cell cryopreservation. Utility Model Content

[0004] The purpose of this invention is to provide a cell cryopreservation tube and its cap placement tray to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cell cryopreservation tube and its cap placement tray, comprising a placement tray with multiple rows of cryopreservation tube placement positions and cap placement positions, the cryopreservation tube placement positions and cap placement positions being arranged alternately.

[0007] As a further improvement, the height of the tube cap placement position is higher than that of the adjacent cryopreservation tube placement position.

[0008] As a further improvement, the tube cap placement position includes several cap holes, which are semi-cylindrical, so that the tube cap can be stably placed sideways in the cap holes when placed; the cryopreservation tube placement position includes several tube holes, which correspond one-to-one with the cap holes.

[0009] As a further improvement, the placement tray is marked with numbers to facilitate counting or identification of the cryopreservation tubes.

[0010] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0011] This design incorporates multiple alternating rows of cryopreservation tube and cap placement positions, with the cap placement positions being higher than the adjacent cryopreservation tube placement positions. This ensures that the caps and cryopreservation tubes are in a one-to-one correspondence during cell cryopreservation, facilitating easy handling and avoiding the possibility of cross-contamination between cells.

[0012] This solution designs a placement position for the pipe cap, allowing it to be stably placed sideways within the cap opening, thus reducing the possibility of microbial contamination caused by prolonged placement of the pipe cap with its opening facing upwards. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / 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 a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] This design incorporates multiple alternating rows of cryopreservation tube placement positions 2 and tube cap placement positions 4. The height of tube cap placement position 4 is higher than the adjacent cryopreservation tube placement position 2, and tube cap placement position 4 is designed with a semi-cylindrical structure. During cell cryopreservation operations, the tube caps can be stably placed sideways in the cap opening 5, corresponding one-to-one with the position of the cryopreservation tubes. Furthermore, the height of the tube caps after placement is similar to the height of the cryopreservation tube opening, ensuring ease of retrieval.

[0021] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0022] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0023] Example 1 of a cell cryopreservation tube and its cap placement tray provided by this utility model:

[0024] like Figure 1-2 As shown, a cell cryopreservation tube and its cap placement tray include a placement tray 1. The placement tray 1 has multiple rows of cryopreservation tube placement positions 2 and cap placement positions 4 integrally formed on it. The cryopreservation tube placement positions 2 and cap placement positions 4 are arranged alternately, and the height of the cap placement position 4 is higher than the height of the adjacent cryopreservation tube placement position 2. This makes the height of the cap similar to the height of the cryopreservation tube opening when placing the cryopreservation tube and the cap, which is convenient for the operator to directly pick up the cap.

[0025] The cap placement position 4 includes several cap holes 5, which are semi-cylindrical, allowing the caps to be stably placed sideways within the cap holes 5, effectively avoiding the possibility of contamination due to prolonged placement of the caps upwards. The cryopreservation tube placement position 2 includes several tube holes 3, which correspond one-to-one with the cap holes 5, effectively preventing confusion between cryopreservation tubes and their corresponding caps, helping to maintain the accuracy of laboratory operations and reducing the risk of cross-contamination between cells.

[0026] To improve operational efficiency and accuracy, the tray is also marked with the number 6 for quick identification and location of the corresponding cryopreservation tubes, reducing potential errors during operation and improving work efficiency.

[0027] In this embodiment, taking a tray 1 for holding 16 2mL cryovials as an example, the cryovial placement positions 2 are arranged in two rows, with eight tube holes 3 in each row. Similarly, the tube cap placement positions 4 are also arranged in two rows, with eight tube holes 3 in each row. The tube cap placement positions 4 and cryovial placement positions 2 are arranged alternately, and the tube holes 3 and cap holes 5 correspond one-to-one. The dimensions of the tray 1 are designed to be 157mm × 78mm × 31mm. The tube cap placement positions 4 are 5mm higher than the tube hole placement positions 3. The diameter of the tube hole 3 is 1.2cm and the depth is 2.6cm. The length of the cap hole 5 is 1.5cm, the width is 1.3cm, and the depth is 0.5cm.
