Abstract
Description
Technical Field
[0001] This utility model relates to the field of adherent cell culture flask technology, and in particular to an adherent cell culture flask that is easy to change the medium. Background Technology
[0002] Cell culture refers to a method of enabling organisms to survive, grow, reproduce, and maintain their main structures and functions by simulating the in vivo environment (sterile, suitable temperature, pH, and certain nutritional conditions, etc.) outside the body. Cell culture is also called cell cloning technology, and the formal term in biology is cell culture technique. Whether for bioengineering as a whole or for biological cloning technology, cell culture is an indispensable process; cell culture itself is the large-scale cloning of cells.
[0003] When using current cell culture methods, cells need to be placed inside the culture flask. Traditionally, cells are stacked, which can cause them to slide, become misaligned, or fall out. In addition, when the culture medium needs to be changed inside the culture flask, the flask needs to be picked up and tilted, making the operation cumbersome and affecting its use.
[0004] A cell culture flask with CN222024389U, disclosed for easy medium replacement, includes a main support box. Bottom inserts are evenly inserted into the bottom surface of the main support box, and a limiting annular groove is formed on the outer side of each bottom insert. The top and bottom surfaces of the main support box have symmetrical mating holes. A discharge pipe is fixedly installed on one side of the main support box, with an end plug connected to the end of the discharge pipe away from the main support box. An extension box is obliquely fixedly installed on the side of the main support box away from the discharge pipe, with a sealing cap connected to the end of the extension box away from the main support box. A top insert is fixedly inserted into one end of each bottom insert. An oblique through hole is formed on one side of the main support box, and an internal thread is provided on the inner side of the discharge pipe. The snap-fit splicing structure makes the flask more stable after assembly, and the direct discharge structure makes medium replacement more convenient.

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Reference Figures 1-6 An adherent cell culture flask for easy medium replacement includes a box assembly 3 with a sealing mechanism installed on it; a connecting mechanism is provided at the lower end of the box assembly 3; the sealing mechanism can be disassembled as needed to facilitate the addition of culture medium and other liquids, while the connecting mechanism allows multiple flasks to be connected to each other for easy storage and quick separation for use.
[0032] Reference Figures 1-3 The sealing mechanism includes a cap assembly 1 threaded onto the upper end of the box assembly 3. A sealing plate assembly 2 is detachably connected to one side of the box assembly 3. The sealing plate assembly 2 and the box assembly 3 are sealed together. During assembly, fasteners are provided on the sealing plate assembly 2, and locking blocks are provided on the box assembly 3. The fasteners and locking blocks correspond to each other, allowing the box assembly 3 and the sealing plate assembly 2 to abut against each other. At the same time, rubber sealing strip components are provided on opposite sides of the sealing plate assembly 2 and the box assembly 3, which can be effectively squeezed to deform them and effectively complete the sealing.
[0033] Reference Figure 1 , 2 3, 6, The connecting mechanism includes two second notches 18 and two first notches 17 on both sides of the lower end of the box assembly 3. A positioning groove 16 is provided on the upper end of the side of the first notch 17 closest to the second notch 18. A movable plate 20 is slidably installed in the second notch 18. Two positioning brackets 19 are installed on the upper end of the side of the movable plate 20 away from the first notch 17. The two positioning brackets 19 located on the upper end of the same movable plate 20 form a group. The two groups of positioning brackets 19 are respectively connected to the two positioning grooves 16. In use, the movable plate 20 is pulled out, which can make the positioning brackets 19 move out of the box assembly 3 and make the positioning brackets 19 correspond to the positioning grooves 16 on the other box assembly 3, so as to effectively complete the connection between the two box assemblies 3. At the same time, the positioning brackets 19 are made of silicone or rubber material, which can deform, making it easy for the positioning brackets 19 to be inserted into or removed from the positioning grooves 16.
[0034] ReferenceFigures 1-6 The lower middle part of the box assembly 3 has a first mounting groove 4. A through pipe 8 is provided through the bottom of the box assembly 3.

Two positioning holes 15 are opened on one side wall of the second mounting groove 11, and the protruding rod 12 corresponds to the positioning holes 15. The rotating rod 13 can drive the connecting shaft 14 to rotate. As the rotating rod 13 rotates, the protruding rod 12 can be inserted into the corresponding positioning hole 15 for effective fixation. When the rotating rod 13 is in a vertical state, it can facilitate the contact shaft 10 to squeeze the discharge pipe 6 to the top of the first mounting groove 4 for sealing. When the rotating rod 13 is in a horizontal state, it can separate the contact shaft 10 from the discharge pipe 6 and separate it from the top of the first mounting groove 4 for easy discharge.
[0036] Reference Figure 3 One end of the box assembly 3 is inclined, and a conical groove 7 is provided at the bottom of the box assembly 3. The through pipe 8 corresponds to one end of the box assembly 3. When the box assembly 3 is laid flat, the liquid can be effectively discharged by flowing along the inclined side of the box assembly 3 to the through pipe 8.
[0037] In this utility model, the cap assembly 1 and the sealing plate assembly 2 can be disassembled and installed, which facilitates liquid replacement and observation. When in use, the box assembly 3 can be laid flat on the side away from the sealing plate assembly 2. After use, the control rod 13 drives the connecting shaft 14 to rotate, which can control the separation of the contact shaft 10 and the discharge pipe 6, and can separate the contact shaft 10 from the side wall of the first mounting groove 4, so that the discharge pipe 6 can be taken out to discharge the waste liquid, thereby completing the liquid replacement operation.
[0038] When storage is required, the cap assembly 1 and sealing plate assembly 2 can be connected to the box assembly 3, while the moving plate 20 is removed from the second notch 18, and the positioning frame 19 and the positioning groove 16 at the lower end of another box assembly 3 are inserted into each other to complete the connection and fixation between multiple box assemblies 3.
