Abstract
Description
Technical Field
[0001] This application relates to the field of biomedical technology, specifically to a sterile connection device for a bioreactor. Background Technology
[0002] Microbial contamination is a serious problem in bioreactor processes used for biomedical research and development. Bacterial or fungal contamination can lead to cell death, abnormal metabolites, and other issues. In such cases, aseptic connection devices are required. A bioreactor aseptic connection device is a specialized device used to establish connections between a bioreactor and other related equipment (such as feed pipes, discharge pipes, gas supply devices, etc.) and can maintain a sterile state during the connection process.
[0003] Chinese utility model patent CN204752695U discloses a sterile quick connector for an animal cell culture bioreactor. This sterile quick connector includes a female connector, a male connector, and a protective sleeve for the male connector that is movably connected to the male connector. The male and female connectors are sealed together. The male connector has a toothed rack, and the inner wall of the protective sleeve has elastic barbs that engage with the toothed rack. This utility model is applicable to the field of microbial culture.
[0004] However, the above-mentioned patents still have the following drawbacks: Although they can solve the problem of aseptic connection between pipes during the microbial reaction process, eliminate joint rotation during the connection process, ensure that the male and female joints will not fall off after connection, and ensure no leakage during use, they cannot conveniently and quickly adjust the height of the access pipe. During the bioreactor process, the height of the access pipe needs to be adjusted at different experimental or production stages. If the height of the access pipe cannot be conveniently and quickly adjusted, it will increase the complexity of operation. Operators will need to spend more time disassembling and reinstalling parts of the device, which not only reduces work efficiency but may also introduce the risk of contamination during operation. In order to solve the above problems, an aseptic connection device for bioreactors is proposed. Utility Model Content

[0007] (II) Technical Solution
[0008] To achieve the above objectives, this application provides the following technical solution: a sterile connection device for a bioreactor, comprising a work frame, a bioreactor body, a connecting pipe, and interfaces. A support assembly is provided on the surface of the work frame, the bioreactor body is disposed on the surface of the support assembly, and multiple interfaces are disposed on the surface of the work frame.

[0017] By adopting the above technical solution, the bottom block is fixed to the bottom of the work frame, and the anti-slip pads bonded to its bottom increase the friction between the device and the placement surface, preventing the device from sliding during operation.
[0018] Preferably, the side surface of the work frame is provided with a support assembly, the support assembly including a connecting frame fixedly connected to the side surface of the work frame, and one end of the connecting frame is fixedly connected to the support frame.

[0022] (III) Beneficial Effects
[0023] This application provides a sterile connection device for a bioreactor. It has the following beneficial effects:
[0024] 1. This bioreactor aseptic connection device, through the coordinated arrangement of a lifting mechanism and a fixing component, allows the height of the connecting pipe to be adjusted by sliding the sliding frame inside the electric slide rail. When the sliding frame slides to the appropriate position, rotating the threaded knob inserts one end into the fixing hole, thereby fixing the sliding frame at the required height. Thus, at different stages of the bioreactor, the height of the connecting pipe can be adjusted according to the actual situation, thereby meeting the dynamic needs of various bioreactor scenarios.
[0025] 2. This bioreactor aseptic connection device, through the coordinated arrangement of the connection component and the snap-fit component, allows the puncture connector to be inserted into the connection port, enabling the elastic diaphragm to tightly wrap around the puncture connector, forming an effective aseptic barrier to prevent external microorganisms from entering the bioreactor or contaminating the materials inside the connection pipe. At the same time, it ensures the sealing of the connection. Furthermore, when the connection pipe is connected to the connection port, the snap-fit block and the snap-fit bracket interlock to prevent the connection pipe from accidentally falling off, ensuring the long-term stability of the connection.

Whether according to the needs of different biological reaction stages or to adapt to the height of different interfaces 103, the position of the connecting pipe 102 can be conveniently adjusted by driving the electric slide rail bracket 201. When the sliding bracket 202 slides to the appropriate position, the threaded knob 402 is rotated so that one end is inserted into the fixing hole 403, thereby fixing the sliding bracket 202 at the required height, ensuring the stability of the connecting pipe 102 during operation, and preventing the reliability of the connection from being affected by accidental sliding.

One end of the connecting frame 601 is fixed to the side surface of the working frame 1, and the support frame 602 at the other end can enhance the stability of the bioreactor body 101.

[0050] Working principle: In use, the connecting pipe 102 to be connected is placed inside the sliding frame 202, and then the pressing mechanism 3 is used to fix the connecting pipe 102 inside the sliding frame 202. Then, the piercing connector 703 is inserted into the connecting port 701, so that the elastic diaphragm 702 can tightly wrap the piercing connector 703. When the connecting pipe 102 is connected to the connecting port 701, the snap-fit block 501 and the snap-fit bracket 502 snap into each other.
