Abstract
Description
Technical Field
[0001] The utility model relates to the field of cell culture devices, in particular to a cell culture bag bracket. Background Art
[0002] Cell culture bags are a type of cell culture device that is made of breathable and hydrophobic plastic materials, depending on the size of the culture area. They can achieve large-scale culture of suspended cells and are suitable for many fields such as vaccines, pharmaceutical industry or monoclonal antibodies. Cell culture bags provide flexible packaging, allowing biopharmaceutical companies to integrate disposable, large-volume culture medium containers and various automated cell culture instruments, disposable bioreactor systems and sterile connection lines without the need for expensive custom services.
[0003] However, although conventional cell culture bags can be placed directly on the shelves of cell culture boxes for cell culture, the internal shelves of the cell culture boxes have insufficient ventilation openings, and the distance between the holes is too large, resulting in the bottom of the cell culture bag in contact with the shelf failing to obtain sufficient ventilation efficiency; some cell culture boxes even have no internal shelves, which is a major defect for cell culture that requires a large amount of air exchange. There is a lack of cell culture bag holders on the market that provide sufficient ventilation and permeability functions for cell culture bags. The cell culture bag holders described in utility models CN202120365383, CN201621484944, CN201920069538, and CN202121649772 still have defects such as insufficient openings, excessive distance between holes, and excessive contact area of the cell culture bag, resulting in the cell culture bag failing to obtain sufficient ventilation efficiency.
[0004] In addition, the number of shelves inside the cell culture incubator is limited, and each shelf can only hold 1 to 2 cell culture bags, which greatly reduces the space utilization of the cell culture incubator. Utility Model Content
[0005] The purpose of the utility model is to overcome the above-mentioned defects and to design a cell culture bag support that can be used in a cell culture box.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a cell culture bag support, characterized in that it includes a multi-layer drawer layer for placing a cell culture bag, and an external support that wraps the entire drawer layer; the drawer layer is composed of a drawer handle, a drawer front interlayer, a drawer bottom layer, and a drawer rear interlayer; the external support is composed of a longitudinal support strip and a transverse support strip. The drawer front interlayer is located at the front side of the drawer layer, and is composed of a front interlayer outer frame and a plurality of front interlayer connecting strips, and is connected to the drawer handle; the drawer bottom layer is located at the bottom of the drawer layer, and is composed of a drawer bottom layer outer frame, a plurality of drawer bottom layer transverse support strips, and a plurality of drawer bottom layer longitudinal support strips; the drawer rear interlayer is located at the rear side of the drawer layer, and is composed of a rear interlayer outer frame and a plurality of rear interlayer connecting strips.
[0007] Furthermore, the drawer layer and the external support are connected in the form of a drawer and an outer frame.
[0008] Furthermore, the drawer layer and the external support are both composed of a number of thinner horizontal and vertical connecting strips, presenting an open structure. The contact area between the drawer layer and the cell culture bag is smaller, allowing the cell culture bags stored in the drawer layer to have sufficient ventilation space.
[0009] Furthermore, the cell culture bag support is a multi-layer structure, consisting of multiple drawer layers, and can culture cells in multiple cell culture bags at the same time.
[0010] Compared with the prior art, the utility model has the following beneficial effects: (1) the contact area between the cell culture bag holder of the utility model and the cell culture bag is smaller, which can provide more sufficient ventilation for the cell culture bag; (2) the cell culture bag holder of the utility model can store multiple cell culture bags, thereby improving the space utilization rate of the cell culture box.

[0014] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below.
[0015] like Figure 1 As shown, a cell culture bag support provided in this embodiment comprises a drawer layer (1) for placing a cell culture bag, and an external support (13) wrapping the entire drawer layer; the drawer layer (1) is composed of a drawer handle (2), a drawer front interlayer (3), a drawer bottom layer (4), and a drawer rear interlayer (5); the external support (13) is composed of a longitudinal support strip (14) and a transverse support strip (15); the drawer front interlayer (3) is located at the front side of the drawer layer, is composed of a front interlayer outer frame (6) and a plurality of front interlayer connecting strips (7), and is connected to the drawer handle (2); the drawer bottom layer (4) is located at the bottom of the drawer layer, is composed of a drawer bottom layer outer frame (8), a plurality of drawer bottom layer transverse support strips (9), and a plurality of drawer bottom layer longitudinal support strips (10); the drawer rear interlayer (5) is located at the rear side of the drawer layer, is composed of a rear interlayer outer frame (11) and a plurality of rear interlayer connecting strips (12).
[0016] Furthermore, the drawer layer (1) and the external support (13) are connected in the form of a drawer and an external frame.
[0017] Furthermore, the drawer layer (1) and the external support (13) are both composed of a plurality of relatively thin horizontal and vertical connecting strips, presenting an open structure. The contact area between the drawer layer and the cell culture bag is smaller, allowing the cell culture bag stored in the drawer layer (1) to obtain a breathable space.
[0018] Further, such as Figure 2 As shown, the cell culture bag support is a multi-layer structure, consisting of multiple drawer layers, and can culture cells in multiple cell culture bags at the same time.
[0019] It is not difficult to find from the above embodiments that the cell culture bag support is more open than the existing cell culture box shelf, the cell culture bag has sufficient ventilation space in the support, and multiple cell culture bags can be placed at the same time. Multiple cell culture bags can be cultured at the same time, thereby improving the space utilization rate of the cell culture box.
[0020] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
