Description

Technical field

[0001] The utility model mainly relates to a medical test liquid homogenizer. [Background Technology]

[0002] A medical test fluid homogenizer is a laboratory device primarily used to homogenize biological samples (such as tissues, cells, or cell components) for subsequent analysis and testing. Its working principle is usually based on high-speed rotation and mechanical impact, so that the sample is broken up and evenly dispersed during the homogenization process. During the homogenization process, the sample is usually placed in a special homogenization cup, and then physically impacted by a high-speed rotating blade or rod-shaped tool. The force generated by this high-speed rotation can break the cell membrane and cell wall, releasing the components inside the cell to form a uniform mixture.

[0003] Existing homogenizers for medical testing fluids generally use blades for cutting, and the shape and size of the blades affect the homogenization effect. Larger blades may be suitable for processing large amounts of samples, but may also cause uneven distribution of samples in the container; smaller blades may be more suitable for delicate sample processing, but the processing speed may be reduced. Selecting the right blade size is crucial for implementation, but homogenizers usually handle a variety of mixed materials, and their sizes vary. It would be very cumbersome to replace the blades for each use. In view of this, we have improved the homogenizer structure and proposed a new universal solution. [Utility Model Content]

[0004] In order to solve at least one of the above problems, the present invention proposes a new structural solution. The present medical test liquid homogenizer adopts the following technical solutions:

[0005] A medical test liquid homogenizer comprises a base and a homogenizing mechanism, wherein the base has a vertical rod, the homogenizing mechanism is mounted on the vertical rod and moves along the vertical rod;

[0006] The homogenizing mechanism includes a horizontal plate, a lifting motor, a homogenizing motor, a stirring blade, a grinding wheel and a frame; the frame, the lifting motor and the homogenizing motor are fixed to the horizontal plate, and the lifting motor is connected to the vertical rod to drive the homogenizing mechanism to move along the vertical rod to adjust the height position of the homogenizing mechanism;

[0007] The frame has a stirring chamber with an open bottom. The rotor of the homogenizing motor passes through the transverse plate and is connected to the stirring blade and the grinding wheel, and the stirring blade and the grinding wheel are located in the stirring chamber. The frame is provided with a discharge groove, which is located above the grinding wheel.

[0008] Preferably, a splash-proof cover is provided at the bottom of the transverse plate, and the splash-proof cover moves with the transverse plate and engages with the container placed on the base to close the opening of the container.

[0009] Preferably, a gap is formed between the edge of the grinding wheel and the inner wall of the frame.

[0010] Preferably, the stirring blade is arranged obliquely on the rotor.

[0011] Compared with the background technology, the utility model has the following beneficial effects:

[0012] This utility model proposes a medical test fluid homogenizer. By combining a stirring blade with a grinding wheel, the stirring blade cuts and crushes large particles, while the grinding wheel performs fine grinding, achieving a uniform, finely divided, and dispersed homogenization effect. Because the grinding wheel, not the stirring blade, performs the primary refining function, this homogenizer eliminates the need for blade replacement, resulting in greater versatility. This product boasts a simple structure, compact fit, and a rational design, offering superior technical and economic performance.

[0020] The following description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to further describe the specific embodiments of the present invention so that the technical solutions and beneficial effects of the present invention are more clearly understood. The following description of the embodiments with reference to the accompanying drawings is for illustrative purposes only and is intended to explain the present invention, but is not to be construed as limiting the present invention.

[0021] The preferred embodiment provided by the present invention is as follows: Figure 1 and Figure 2 As shown, a medical test liquid homogenizer includes a base 1 and a homogenizing mechanism 2. The base 1 has a vertical rod 11. The homogenizing mechanism 2 is mounted on the vertical rod 11 and moves along the vertical rod 11.

[0022] The homogenizing mechanism 2 includes a transverse plate 21, a lifting motor 22, a homogenizing motor 23, a stirring blade 24, a grinding wheel 25 and a frame 26. The frame is a cylindrical ring, and the surface of the grinding wheel 25 is sandpaper-like; the frame 26, the lifting motor 22 and the homogenizing motor 23 are fixedly connected to the transverse plate 21, and the lifting motor 22 is connected to the vertical rod 11 to drive the homogenizing mechanism 2 to move along the vertical rod 11 to adjust the height position of the homogenizing mechanism 2; the end face of the vertical rod 11 is provided with a tooth pattern 14, and the rotating end of the lifting motor 22 is installed with a gear, and the gear is engaged with the tooth pattern to control the lifting and lowering of the homogenizing mechanism.

[0023] The frame 26 has a stirring chamber 27, the bottom end of which is open to allow the mixed liquid to enter the stirring chamber 27; the rotor 29 of the homogenizing motor 23 passes through the horizontal plate 21 and is connected to the stirring blade 24 and the grinding wheel 25, and the stirring blade 24 and the grinding wheel 25 are located in the stirring chamber 27; the frame 26 is provided with a discharge groove 28, which is located above the grinding wheel 25; the stirring blade 24 is tilted on the rotor 29 so that the stirring blade 24 can suck the mixed liquid into the stirring chamber 27 when it rotates; there is a gap between the edge of the grinding wheel 25 and the inner wall of the frame 26.

[0024] A splash-proof cover 12 is provided at the bottom of the horizontal plate 21. The splash-proof cover is a circular gasket made of rubber. The splash-proof cover 12 moves with the horizontal plate 21 and engages and presses with the container 3 placed on the base 1 to close the opening of the container 3 and prevent the liquid in the container 3 from splashing during stirring.

[0025] Homogenization process: Place the container 3 containing the mixed liquid on the base 1, activate the lifting motor 22 to lower the homogenization mechanism 2, and the stirring blade 24 and grinding wheel 25 enter the mixed liquid along with the frame 26. Activate the homogenization motor 23, and the grinding wheel 25 and stirring blade 24 rotate simultaneously at high speed. The stirring blade 24 performs an initial stirring and breaking up of the mixed liquid. The broken up mixed liquid passes through the gap between the edge of the grinding wheel 25 and the inner wall of the frame 26. The surface of the grinding wheel 25 and the edge of the grinding wheel 25 and the inner wall of the frame 26 perform a secondary grinding to further refine the mixed liquid. The refined mixed liquid flows out of the discharge groove 28 of the frame 26 and mixes with the container 3. Through repeated cycles, the mixed liquid is broken up and evenly dispersed during the homogenization process. This structure combines the stirring blade 24 and the grinding wheel 25, uses the stirring blade 24 to cut and crush large particles, and cooperates with the grinding wheel 25 to perform fine grinding to achieve a uniform, fine, dispersed and homogenized effect. Since the grinding wheel 25 plays the main refining role in this structure, rather than the stirring blade 24, this homogenizer structure does not need to replace the stirring blade 24, and has wider versatility.

The schematic expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0027] Through the description of the above structure and principle, technical personnel in the relevant technical field should understand that the present invention is not limited to the above specific implementation methods, and improvements and substitutions based on the present invention using the well-known technology in the field all fall within the scope of protection of the present invention and should be defined by the claims.
