Description
Technical Field
[0001] This utility model relates to the technical field of microbial sample processing, specifically a mixing device for processing liquid and sample. Background Technology
[0002] Sample processing solutions are widely used chemical reagents in biological experiments. They can be used for the pretreatment, extraction, and purification of biological samples (such as blood, urine, tissue, genomic DNA, etc.). When using sample processing solutions, the biological sample to be processed needs to be mixed with the sample processing solution first, and then processed and separated. The usage method is as follows: 1. Select a suitable sample processing solution according to the experimental requirements; 2. Add an appropriate amount of sample processing solution to the biological sample to be tested and mix well; 3. Process and separate according to the steps in the kit instructions.
[0003] Currently, there are two methods for mixing the processing solution and the sample: manual mixing and electric mixing. The electric mixing device is mainly a vortex mixer. When using a vortex mixer to mix a single test tube or conical flask, the user needs to hold the top of the test tube to fix it. Long-term use can easily cause numbness in the user's hand and cause discomfort. Therefore, it is necessary to design a mixing device for the processing solution and the sample to improve the above problems. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a mixing device for processing liquid and sample.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A mixing device for a processing solution and a sample, comprising:
[0007] The vortex mixing device is mounted on a swaying chassis, the top of which is provided with a groove, and the top of the vortex mixing device is provided with a top limiting component that works in conjunction with the swaying chassis.
[0008] Preferably, the top limiting component includes a support column, which is fixedly installed on the rear side of the vortex mixing device. A height adjusting rod is slidably connected to the front side of the support column, and a top plate is installed at the bottom of the height adjusting rod. The centers of the top plate and the swaying base are located on the same vertical axis.
[0009] Preferably, the bottom of the top plate is provided with two limiting arc plates, which slide at the bottom of the top plate, and flexible thick pads are adhered to the opposite side of each limiting arc plate.
[0010] Preferably, a spherical movable rod is fixedly installed on the top of the top plate, and the top of the spherical movable rod rotates in the inner cavity at the bottom of the height adjusting rod.
[0011] Preferably, the bottom of the top plate is provided with a movable groove, and the inner cavity of the movable groove is rotatably connected to a bidirectional threaded rod extending to the outside. The top of the limiting arc plate slides in the inner cavity of the movable groove, and the top of the limiting arc plate is threadedly connected to the surface of the bidirectional threaded rod. A rotating block is fixedly installed at one end of the bidirectional threaded rod.
[0012] Preferably, a stop plate is mounted at the center of the bottom of the top plate by a plurality of springs, the springs being arranged in a ring array on top of the stop plate.
[0013] Preferably, a screw is rotatably connected to the inner cavity of the support column, a sliding block is fixedly installed on the rear side of the height adjustment rod, the sliding block is threadedly connected to the surface of the screw, and the top of the screw extends to the outer side of the support column and is fixedly installed with an anti-slip rotating block.
[0014] Preferably, mounting plates are welded to both the left and right sides of the support column, and the mounting plates are fixedly installed on the rear side of the vortex mixing device by screws.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model uses a top limiting component to partially limit the top of the test tube or conical flask, simulating and replacing the grip of a human hand, thereby preventing the user from directly contacting the test tube or conical flask during mixing and reducing discomfort such as numbness.
[0017] 2. By using the support column and the height adjustment rod together, this utility model allows for flexible adjustment of the height adjustment rod when the height of the test tube or conical flask changes, thereby enabling the mixing of the processing liquid and sample in test tubes or conical flasks of different heights.
[0018] 3. This utility model, through the setting of two limiting arc plates, allows for flexible adjustment of the distance between the two limiting arc plates according to the actual size of the test tube, thus satisfying the clamping and limiting of test tubes or conical flasks of different sizes.
[0019] 4. This utility model utilizes the combined use of a retaining plate and a spring. The spring's rebound force presses the retaining plate downwards, and the retaining plate presses the test tube downwards. When the test tube is shaken to mix the treatment liquid and sample in the test tube, the test tube can be shaken up and down more frequently, avoiding rigid contact between the test tube and the top plate, which could damage the test tube.

Detailed Implementation
[0027] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0028] In the following description, embodiments of the mixing device for the processing liquid and the sample of the present invention will be described with reference to the accompanying drawings.
[0029] Figure 1-4 This invention illustrates a mixing apparatus for a processing solution and a sample according to an embodiment of the present invention, comprising:
[0030] A vortex mixing device 1 is mounted on a wobbling base 2. The top of the wobbling base 2 has a groove. The top of the vortex mixing device 1 is equipped with a top limiting component that works in conjunction with the wobbling base 2. Specifically, the top limiting component includes a support column 3, which is fixedly mounted on the rear side of the vortex mixing device 1. Mounting plates 17 are welded to both sides of the support column 3 and are fixed to the rear side of the vortex mixing device 1 with screws. A height adjusting rod 4 is slidably connected to the front side of the support column 3. Through the cooperation of the support column 3 and the height adjusting rod 4, when the height of the test tube or conical flask changes... The height of the height adjustment rod 4 can be flexibly adjusted according to needs, thereby enabling the mixing of treatment liquid and sample in test tubes or conical flasks of different heights. Specifically, a screw 14 is rotatably connected to the inner cavity of the support column 3, and a sliding block 15 is fixedly installed on the rear side of the height adjustment rod 4. The sliding block 15 is threaded onto the surface of the screw 14. The top of the screw 14 extends to the outside of the support column 3 and is fixedly installed with an anti-slip rotating block 16. A top plate 5 is installed at the bottom of the height adjustment rod 4. The center of the top plate 5 and the shaking base plate 2 are located on the same vertical axis. Specifically, two limiting arc plates 7 are provided at the bottom of the top plate 5. The 7 slides at the bottom of the top plate 5. Through the setting of two limiting arc plates 7, the distance between the two limiting arc plates 7 can be flexibly adjusted according to the actual size of the test tube, satisfying the clamping and limiting of test tubes or conical flasks of different sizes. Flexible thick pads 8 are adhered to opposite sides of the limiting arc plates 7. Specifically, the bottom of the top plate 5 has a movable groove 11. A bidirectional threaded rod 9 extending outwards is rotatably connected to the inner cavity of the movable groove 11. The top of the limiting arc plate 7 slides within the inner cavity of the movable groove 11, and the top of the limiting arc plate 7 is threadedly connected to the surface of the bidirectional threaded rod 9. A rotating block 10 is fixedly installed at one end of the bidirectional threaded rod 9. A spherical movable rod 6 is fixedly installed on the top of the top plate 5. The top of the spherical movable rod 6 rotates in the inner cavity at the bottom of the height adjustment rod 4. Specifically, a stop plate 12 is installed at the center of the bottom of the top plate 5 through multiple springs 13. The springs 13 are arranged in a ring on the top of the stop plate 12. Through the cooperation of the stop plate 12 and the springs 13, the spring force of the springs 13 presses the stop plate 12 downward, and the stop plate 12 presses the test tube downward. When the bottom plate 2 is shaken to mix the treatment liquid and sample in the test tube, the test tube can be shaken up and down more to avoid rigid contact between the test tube and the top plate 5, which would cause damage to the test tube.
[0031] Working principle: When using this utility model, the user places the test tube vertically in the center of the groove in the shaking base 2, then rotates the anti-slip rotating block 16 to drive the screw 14 to rotate in the inner cavity of the support column 3, thereby causing the sliding block 15 and the height adjustment rod 4 to slide downwards until the abutment 12 contacts the top of the test tube. Then, rotating the rotating block 10 drives the bidirectional threaded rod 9 to rotate in the inner cavity of the movable groove 11, thereby causing the two limiting arc plates 7 to slide towards each other, limiting the top of the test tube. Then, the vortex mixing device 1 is activated to drive the shaking base 2 to shake, thereby causing the bottom of the test tube to shake to achieve mixing of the treatment liquid and the sample. During the mixing operation, the spherical movable rod 6 will rotate in the inner cavity at the bottom of the height adjustment rod 4. The top limiting component can be installed separately on other similar mixing devices to modify existing mixing devices and meet the need for freeing up hands.
[0032] In summary, this mixing device for the treatment solution and the sample partially restricts the top of the test tube or conical flask through a top limiting component, simulating and replacing the grip of a human hand. This avoids direct contact between the user and the test tube or conical flask during mixing, reducing discomfort such as numbness.
[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
