Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment technology, and in particular to a disposable biological reaction bag support. Background Technology

[0002] Bioreactors are indispensable in the production and manufacturing of bioproducts. Bioreactors are known to be divided into reusable bioreactors and single-use bioreactors. Reusable bioreactors require comprehensive sterilization and disinfection before use, and cleaning after batch culture. This not only increases labor costs but also extends the entire product development cycle. Therefore, the overall cost may not be cost-effective. As a result, single-use bioreactors are more popular. The reaction vessel for holding culture medium and culture medium in a single-use bioreactor is made of special plastic with sufficient thickness and toughness. The single-use bioreactor bag needs to be placed inside a stainless steel reaction vessel, and a bracket needs to be set on the stainless steel reaction vessel to install the single-use bioreactor bag.

[0003] However, existing bioreactor support brackets have fixed bracket dimensions, which cannot hold bioreactor bags of different sizes. Furthermore, the number and layout of the bioreactor support brackets cannot be changed, thus making them unsuitable for bioreactor bags of different shapes and narrowing the applicability of the equipment. Therefore, a disposable bioreactor support bracket is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disposable bioreactor bag support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disposable biological reaction bag support, including a mounting frame, connecting ears fixedly provided on both sides of the mounting frame, a connecting block fixedly provided on the top inner wall of the mounting frame, four insertion holes provided on the outside of the connecting block, slots provided on both sides of the inner wall of the insertion hole, positioning grooves provided on the top and bottom inner walls of the insertion hole, a fixing structure provided in the insertion hole, and a suspension structure fixedly installed on one side of the fixing structure through the mounting block.

[0006] As a further description of the above technical solution:

[0007] The fixing structure includes a plug block that is inserted into the socket. The mounting block is fixedly connected to one side of the plug block. Multiple sliding rods are fixedly provided inside the plug block. Two connecting plates are movably provided on the multiple sliding rods. Positioning blocks and pressure blocks are fixedly provided on the opposite sides of the two connecting plates. Locking strips are fixedly provided on both sides of the plug block.

[0008] As a further description of the above technical solution:

[0009] A first spring is fitted onto the slide rod, and the two ends of the first spring are respectively attached to the sides of the two connecting plates that are close to each other.

[0010] As a further description of the above technical solution:

[0011] The connecting plate has a circular hole, and a sealing ring is installed inside the circular hole. The inner wall of the sealing ring is in contact with the slide rod.

[0012] As a further description of the above technical solution:

[0013] The suspension structure includes a sleeve fixedly connected to the mounting block. The surface of the sleeve is provided with multiple positioning holes, and the inner wall of the sleeve is provided with a limiting groove. A telescopic rod is movably provided inside the sleeve. The surface of the telescopic rod is provided with a storage hole, and a positioning rod is movably provided inside the storage hole. The positioning rod and the positioning hole are adapted to each other, and a hook is fixedly provided at one end of the telescopic rod.

[0014] As a further description of the above technical solution:

[0015] A second spring is fixedly installed inside the storage hole, and a guide plate is fixedly installed on the top of the second spring. The top of the guide plate is fixedly connected to the positioning rod, and the guide plate is movably connected to the storage hole.

[0016] As a further description of the above technical solution:

[0017] The telescopic rod is fixedly provided with two limiting blocks on its exterior, and the limiting blocks and the limiting grooves are movably connected.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this disposable bioreactor bag support, through the setting of a sleeve, positioning hole, limiting groove, telescopic rod, storage hole, second spring, guide plate, positioning rod and hook, compresses the positioning rod inward, and the positioning rod compresses the guide plate. When the positioning rod is fully retracted into the storage hole, the telescopic rod can be pulled. The telescopic rod drives the hook and positioning rod. When the positioning rod moves to the position of the positioning hole, the second spring pushes the guide plate upward, and the guide plate then drives the positioning rod to pop out of the positioning hole, thus positioning the telescopic rod. The adjustment can be stopped when the position of the hook is adapted to the bioreactor bag. The adjustable telescopic rod can be used for bioreactor bags of different sizes, improving the practicality of the equipment.

[0020] 2. Compared with existing technologies, this disposable bioreactor bag support, by setting up insert blocks, sliding rods, connecting plates, pressure blocks, positioning blocks, locking strips, and connecting blocks, allows for selective installation of the suspension structure based on the shape of the disposable bioreactor bag during use. If the bioreactor bag is cylindrical, four suspension structures are required. Pressing two pressure blocks inward causes the two connecting plates to move inward, which in turn move the positioning block inward. Once the positioning block is fully retracted into the insert block, the insert block is inserted into the insertion hole. Then, the pressure block is released, and the first spring resets the two connecting plates. The connecting plates then move the positioning block, inserting it into the positioning groove, thus installing the suspension structure. The installation of four suspension structures allows for suspension of the cylindrical bioreactor bag in four directions, maintaining the parallelism of the bag during suspension. If the bioreactor bag is cubic, only two suspension structures are required. The fixed structure allows for rapid installation of the suspension structure, enabling the equipment to suspend bioreactor bags of different shapes and expanding its applicability.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 6 The present invention provides a disposable biological reaction bag support: including a mounting frame 1, with connecting ears 2 fixedly provided on both sides of the mounting frame 1, a connecting block 3 fixedly provided on the top inner wall of the mounting frame 1, four insertion holes 4 provided on the outside of the connecting block 3, slots 5 provided on both sides of the inner wall of the insertion hole 4, and positioning grooves 6 provided on the top inner wall and bottom inner wall of the insertion hole 4.

[0031] To facilitate rapid installation of the suspension structure 8, a fixing structure 7 is provided within the insertion hole 4. The fixing structure 7 includes an insertion block 701 that inserts into the insertion hole 4. An installation block is fixedly connected to one side of the insertion block 701. Multiple sliding rods 702 are fixedly installed within the insertion block 701. Two connecting plates 703 are movably mounted on the sliding rods 702. Each connecting plate 703 has a circular hole containing a sealing ring. The inner wall of the sealing ring is in contact with the sliding rod 702. A first spring is fitted onto each sliding rod 702, with both ends of the first spring contacting the adjacent sides of the two connecting plates 703. Positioning blocks 705 and pressure blocks 704 are fixedly mounted on the opposing sides of the two connecting plates 703. Clips are fixedly mounted on both sides of the insertion block 701. The two pressure blocks 704 are pressed inward by the strip 706. The pressure blocks 704 then drive the two connecting plates 703. The two connecting plates 703 squeeze the first spring and drive the positioning block 705 to move inward. When the positioning block 705 is fully retracted into the insertion block 701, the insertion block 701 is inserted into the insertion hole 4. Then the pressure block 704 is released, and the first spring causes the two connecting plates 703 to return to their original positions. The connecting plates 703 drive the positioning block 705 to move and insert it into the positioning groove 6, thereby realizing the installation of the suspension structure 8. The setting of the fixing structure 7 can realize the quick installation of the suspension structure 8. The user can decide the number and layout of the suspension structure 8 according to the actual needs, so that the equipment can suspend bioreactor bags of different shapes.

[0032] To accommodate bioreactor bags of different sizes, a suspension structure 8 is fixedly mounted on one side of the fixed structure 7 via an mounting block. The suspension structure 8 includes a sleeve 801 fixedly connected to the mounting block. The sleeve 801 has multiple positioning holes 802 on its surface and a limiting groove 803 on its inner wall. A telescopic rod 804 is movably mounted inside the sleeve 801. Two limiting blocks are fixedly mounted on the outside of the telescopic rod 804, and the limiting blocks are movably connected to the limiting groove 803. A receiving hole 805 is provided on the surface of the telescopic rod 804. A positioning rod 808 is movably mounted inside the receiving hole 805. A second spring 806 is fixedly mounted inside the receiving hole 805. A guide plate 807 is fixedly mounted on the top of the second spring 806. The top of the guide plate 807 is fixedly connected to the positioning rod 808, and the guide plate 807 is movably connected to the receiving hole 805. Positioning rod 808 and positioning hole 802 are adapted to each other. One end of telescopic rod 804 is fixedly equipped with hook 809. When positioning rod 808 is pressed inward, positioning rod 808 presses guide plate 807, and guide plate 807 presses second spring 806. When positioning rod 808 is fully retracted into storage hole 805, telescopic rod 804 can be pulled. Telescopic rod 804 drives hook 809 and positioning rod 808. When positioning rod 808 moves to the position of positioning hole 802, second spring 806 pushes guide plate 807 upward. Guide plate 807 then drives positioning rod 808 to pop out of positioning hole 802, realizing positioning of telescopic rod 804. Adjustment can be stopped when the position of hook 809 is adapted to bioreactor bag. Adjustable telescopic rod 804 can be used for bioreactor bags of different sizes, improving the practicality of equipment.

[0033] Working Principle: In use, the suspension structure 8 is selectively installed according to the shape of the disposable bioreactor bag. If the bioreactor bag is cylindrical, four suspension structures 8 need to be installed. The two pressure blocks 704 are pressed inwards, which in turn drive the two connecting plates 703. The two connecting plates 703 compress the first spring and drive the positioning block 705 inwards. When the positioning block 705 is fully retracted into the insertion block 701, the insertion block 701 is inserted into the insertion hole 4. Then, the pressure blocks 704 are released, and the first spring causes the two connecting plates 703 to return to their original position. The connecting plates 703 drive the positioning block 705 to move, causing it to insert into the positioning groove 6, thus completing the installation of the suspension structure 8. The installation of four suspension structures 8 allows for suspension of the cylindrical bioreactor bag in four directions, maintaining the parallelism of the bioreactor bag during suspension. If the bioreactor bag is cubic... Only two suspension structures 8 need to be installed. Before suspension, the extension length of the hook 809 can be adjusted according to the specifications of the bioreactor bag. The positioning rod 808 is pressed inward, which presses the guide plate 807. The guide plate 807 presses the second spring 806. When the positioning rod 808 is fully retracted into the storage hole 805, the telescopic rod 804 can be pulled. The telescopic rod 804 drives the hook 809 and the positioning rod 808. When the positioning rod 808 moves to the position of the positioning hole 802, the second spring 806 pushes the guide plate 807 upward. The guide plate 807 then drives the positioning rod 808 to pop out of the positioning hole 802, thus positioning the telescopic rod 804. The adjustment can be stopped when the position of the hook 809 is adapted to the bioreactor bag. The adjustable telescopic rod 804 can be used for bioreactor bags of different sizes, improving the practicality of the equipment.
