Description

Technical Field

[0001] The utility model belongs to the technical field of cell culture bottles, in particular to a cell culture bottle. Background Art

[0002] Some cells and tissues can grow in suspension, but a considerable number of mammalian cells need to adhere to a surface. Therefore, in addition to having good transparency, non-toxicity and sterility, the culture flasks, culture plates and culture dishes used to provide an in vitro cell culture environment also need to be surface modified to enable them to adhere, divide and grow.

[0003] For example, the Chinese patent with publication number CN215856162U discloses a cell culture bottle, which belongs to the technical field of cell culture bottles. The cell culture bottle includes a bottle body and a support assembly. The cells to be cultured are first placed inside the bottle body. During the cell incubation process, when the bottle body needs to be tilted, the bottle body can be placed inside the placement rack, and then the electric push rod can be started. The electric push rod can push the tooth plate to move. At the same time, the first gear is connected to the tooth plate by transmission. The placement rack is set on one side of the support rack, and one end of the shaft rod is fixedly connected to the placement rack. Therefore, when the electric push rod pushes the tooth plate to move, the tooth plate can drive the first gear to rotate. When the first gear rotates, it will drive the shaft rod to rotate on the support rack, which can drive the placement rack to be tilted and adjusted, so that the operator does not need to tilt it by hand to achieve the tilting effect, thereby reducing the workload of the operator and improving practicality.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: it is not convenient to take multiple culture bottles at the same time when taking the culture bottles, and the surface of the culture bottles is relatively smooth when the staff takes the culture bottles. Some staff members wear sterilized gloves, which are easy to slip when taking the culture bottles. In addition, some cells need a certain amount of oxygen to grow, and some culture bottles need to open the bottle caps to allow oxygen to enter the culture bottles, which will cause bacteria in the air to enter the culture bottles and affect the growth of cells. In view of this, we propose a cell culture bottle. Utility Model Content

[0006] The purpose of the utility model is to provide a cell culture bottle to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a cell culture bottle, comprising:

[0008] A placement box, wherein a plurality of mounting grooves are provided in the placement box, a buffer pad is fixedly installed on the inner wall of the mounting groove, a culture bottle is arranged in the buffer pad, a mounting block is fixedly installed at the bottom of the culture bottle and located in the mounting groove, a limiting groove is provided on one side of the mounting block, a slide groove connected to the limiting groove is provided on one side of the mounting groove, a limiting block is slidably installed in the slide groove, and one side of the limiting block extends to the limiting groove, a plurality of springs fixed to the inner wall of the slide groove are fixedly installed on the side of the limiting block away from the mounting groove, and an L-shaped rod is fixedly installed on the side of the limiting block away from the mounting groove, and the upper end of the L-shaped rod passes through the slide groove and extends to the outside, a connecting pipe is fixedly installed on the culture bottle, a sealing ring is plugged and installed in the connecting pipe, a plurality of filter membranes are fixedly installed in the sealing ring, and an anti-slip ring is fixedly installed on the culture bottle and located above the mounting groove.

[0009] In the technical solution, when it is necessary to move multiple culture bottles, the culture bottles together with the mounting block are inserted into the mounting groove through the buffer pad, so that the bottom of the mounting block squeezes the limit block. Since one side of the limit block is an inclined structure, when squeezed, the limit block will move together with the L-shaped rod in the direction away from the mounting groove. At this time, the plurality of springs will shrink when squeezed until the limit block completely enters the slide groove, and then the mounting block will continue to move downward until the bottom of the mounting block contacts the bottom of the mounting groove. Then, under the action of the rebound of the plurality of springs, the plurality of springs will move against the limit block until one side of the limit block is inserted into the limit groove, so that the mounting block and the culture bottle can be fixed in the mounting groove. At this time, the side wall of the culture bottle will be in close contact with the inner wall of the buffer pad.

[0010] When taking out the culture bottle, the staff member manually moves the L-shaped rod to make the L-shaped rod slide in the slide groove and move in the direction away from the installation groove. Subsequently, the L-shaped rod will drive the limit block to move together until one side of the limit block is completely moved out of the limit groove and the limit block is completely entered into the slide groove. At this time, the installation block will be released and then the culture bottle can be pulled upward to take it out. With the effect of the anti-slip ring, the staff member can hold the culture bottle more conveniently, and can avoid the situation that the culture bottle is easy to slip when the staff member takes it while wearing gloves. In addition, with the effect of the connecting tube, the sealing ring and several filter membranes, it can ensure that the outside air can enter the culture bottle without opening the bottle cap on the culture bottle. In addition, with the effect of several filter membranes, the bacteria in the air can be filtered cleanly, so that the air entering the culture bottle does not have any bacteria, ensuring that it will not affect the growth of cells.

[0011] In the above technical solution, further, one side of the limit block is in an inclined structure.

[0012] In this technical solution, it is ensured that when the culture bottle is pressed, the bottom of the mounting block will squeeze the limiting block so that the limiting block can enter the slide groove.

[0013] In the above technical solution, further, the side wall of the culture bottle is in close contact with the inner wall of the buffer pad, and the filtration pore size of the filter membrane is 0.2μm-0.45μm.

[0014] In this technical solution, it is ensured that the cushion pad can cushion the culture bottle, thereby ensuring that the cells in the culture bottle will not be damaged; it is ensured that the bacteria in the air can be filtered to avoid affecting the growth of the cells in the culture bottle.

[0015] In the above technical solution, further, the connecting tube is communicated with the inner cavity of the culture bottle, and the culture bottle is plug-fitted with the buffer pad.

[0016] In this technical solution, it is ensured that the outside air can enter the inner cavity of the culture bottle through the through tube; and it is ensured that the culture bottle can be inserted into the buffer pad.

[0017] In the above technical solution, further, the L-shaped rod is slidably connected to the slide groove, and the cross-section of the buffer pad is a U-shaped structure.

[0018] In the technical solution, it is ensured that the L-shaped rod can slide in the slide groove; it is ensured that the buffer pad can buffer the culture bottle.

[0019] In the above technical solution, further, the installation block is plug-fitted into the installation slot, and the limiting block is plug-fitted into the limiting slot.

[0020] In this technical solution, it is ensured that the mounting block can be inserted into the mounting groove; and it is ensured that the limiting block can be inserted into the limiting groove.

[0021] The beneficial effects of the utility model are:

[0022] 1. For the cell culture bottle, when the culture bottle is moved, the culture bottle together with the mounting block is inserted into the mounting groove through the buffer pad, so that the bottom of the mounting block squeezes the limit block. Because one side of the limit block is in an inclined structure, when squeezed, the limit block will move together with the L-shaped rod in a direction away from the mounting groove. At this time, the plurality of springs will shrink when squeezed until the limit block completely enters the slide groove, and then the mounting block will continue to move downward until the bottom of the mounting block contacts the bottom of the mounting groove. Then, under the action of the rebound of the plurality of springs, the plurality of springs will move against the limit block until one side of the limit block is inserted into the limit groove, so that the mounting block and the culture bottle can be fixed in the mounting groove. At this time, the side wall of the culture bottle will be in close contact with the inner wall of the buffer pad. Through the above operation, the remaining culture bottles can be fixed in the remaining mounting grooves respectively, ensuring that multiple culture bottles can be carried at one time, which is more convenient.

[0023] 2. When taking out the cell culture bottle, the staff can hold the culture bottle more conveniently due to the anti-slip ring, which can prevent the staff from slipping when taking the culture bottle while wearing gloves. In addition, due to the connecting tube, the sealing ring and a plurality of filter membranes, it can ensure that the outside air can enter the culture bottle without opening the bottle cap on the culture bottle. In addition, due to the action of the plurality of filter membranes, the bacteria in the air can be filtered out, so that the air entering the culture bottle is free of bacteria, ensuring that the growth of cells will not be affected.
