Description

Technical Field

[0001] This utility model belongs to the field of concentration equipment, specifically an exosome concentration device for exosome-loaded drugs. Background Technology

[0002] Exosome drug delivery is an emerging drug delivery technology that utilizes exosomes as drug delivery carriers. Exosomes are tiny membrane vesicles secreted by cells, containing cellular proteins, lipids, and RNA. They can transmit information between cells through body fluids and have certain biocompatibility and targeting properties. Exosome concentration equipment is a specialized device used to separate and concentrate cellular exosomes. These devices play a key role in exosome drug delivery research, effectively extracting and concentrating exosomes from body fluid samples to provide sufficient exosome quantities for subsequent drug loading and application.

[0003] According to application number 202321631277.5, an exosome separation and concentration device is disclosed, including a separation and concentration device body, a discharge port, and a fixed cylinder. The fixed cylinder is provided at the top of the separation and concentration device body, and the discharge port is provided on one side of the fixed cylinder. The separation and concentration cylinder is provided inside the fixed cylinder. The inner wall of the separation and concentration cylinder is provided with a disassembly structure. The outer side of the separation and concentration cylinder is provided with a through hole. Limiting structures are provided on both sides of the separation and concentration cylinder. A motor is provided inside the separation and concentration device body. A control panel is provided on one side of the front end of the separation and concentration device body. This comparative case, by setting a limiting structure, makes the separation and concentration cylinder more stable when rotating. Therefore, by using the combination of the limiting rod and the roller groove, the separation and concentration cylinder can be limited, making the separation and concentration cylinder more stable when rotating, thereby improving the limiting effect.

[0004] This comparative case effectively solved the problem that centrifuge tubes are prone to positional displacement during rotation, leading to tube detachment and failure of exosome raw material separation and concentration. However, the device is structurally robust and cannot be disassembled for cleaning, which can leave liquid residue inside, affecting the purity of subsequent exosome concentration.

The inner cavity of the support ring 601 is movably connected to a fixing ring 602 through a bearing. The top of the fixing frame 3 is fixedly connected to the bottom of the fixing ring 602. The inner cavity of the fixing ring 602 is fixedly connected with a connecting plate 603.

[0024] like Figure 1-4 As shown, the sealing cover 2 is used to seal the top of the operating box 1, thereby providing a closed operating space for the concentration operation. The fixing frame 3 is used to fix the filter screen 4. The motor 5 can drive the fixing frame 3 and the filter screen 4 to rotate so as to carry out sample extraction. The positioning mechanism 6 plays a role in facilitating the installation of the fixing frame 3, so as to disassemble and clean the fixing frame 3, thereby effectively reducing the exosome residue inside the equipment and preventing the residue from affecting the quality of the subsequent finished products.

[0025] Example 2

[0026] Reference Figure 3 and 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, the top of the connecting plate 603 is provided with a positioning groove 604, the output shaft of the motor 5 passes through the inner cavity of the operating box 1 and is connected to the positioning block 605. The output shaft of the motor 5 is movably connected to the inner wall of the sealing cover 2 through a bearing, and the bottom of the positioning block 605 extends into the inner cavity of the positioning groove 604 and engages with the inner cavity of the positioning groove 604.

[0028] The support ring 601 has through holes 606 around its top. The operation box 1 has positioning pins 607 fixedly connected around its top. The top of the positioning pins 607 extends into the inner cavity of the through holes 606 and is movably connected to the inner cavity of the through holes 606. The sealing cover 2 has positioning holes 608 around its bottom. The top of the positioning pins 607 engages with the inner cavity of the positioning holes 608.

[0029] like Figure 3 and 4 As shown, after the positioning pin 607 passes through the through hole 606 and is inserted into the inner cavity of the positioning hole 608, the sealing cover 2 and the support ring 601 can be positioned, thereby fixing the operating box 1, the sealing cover 2 and the support ring 601. The fixing ring 602 is used to support the fixing frame 3. Since the inner cavity of the fixing ring 602 and the support ring 601 are movably connected by a bearing, after the positioning block 605 is inserted into the inner cavity of the positioning groove 604, the support ring 601 and the fixing ring 602 can be positioned, so that the output shaft of the motor 5 can drive it to rotate, thereby driving the fixing frame 3 and the filter screen 4 to rotate.

[0030] Example 3

[0031] Reference Figure 1 and 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] In this embodiment, a base 7 is fixedly connected to the bottom of the operation box 1, and support legs 8 are fixedly connected to both sides of the base 7. A base plate 9 is fixedly connected to the bottom of the support legs 8.

The discharge pipe 10 facilitates the discharge of excrement from the operation box 1. The fixing bracket 11 is used to fix the motor 5. The lifting rod 12 facilitates the removal of the sealing cover 2 so that it can be removed from the top of the operation box 1.

[0036] In use, first move the fixed frame 3 to move the support ring 601 to the top of the operating box 1, and insert the positioning pin 607 into the through hole 606. Then add the raw material into the fixed frame 3. After that, move the sealing cover 2 by taking the lifting rod 12 and move the sealing cover 2 to the top of the operating box 1. Slowly move it down so that the positioning block 605 is inserted into the inner cavity of the positioning groove 604 and the positioning pin 607 is inserted into the inner cavity of the positioning hole 608. Then start the motor 5. Since the inner cavity of the fixed ring 602 and the support ring 601 are movably connected by the bearing, after the positioning block 605 is inserted into the inner cavity of the positioning groove 604, the support ring 601 and the fixed ring 602 can be positioned, so that the output shaft of the motor 5 can drive it to rotate, which in turn can drive the fixed frame 3 and the filter screen 4 to rotate, and perform the exosome separation operation.
