Description

Technical Field

[0001] The invention relates to the technical field of medical testing, in particular to an oscillating mixer for medical testing samples. Background Art

[0002] Medical testing is a medical tool used to evaluate and diagnose diseases. It obtains information about patient health status by collecting and analyzing patient samples (such as blood, urine, tissue, etc.). Its purpose is to help doctors make precise diagnoses, assess the severity of the disease, develop treatment plans, and monitor the effectiveness of treatment. Medical testing plays a vital role in diagnosis and treatment, and its application range is very wide. It can not only be used for early detection of diseases, such as discovering tumor markers through blood tests, but also for detecting kidney function through urine analysis. In addition, medical testing technology can also help monitor the progression of the disease and treatment response, such as evaluating diabetes by regularly testing blood sugar levels. At the same time, it can also be used to evaluate the efficacy and side effects of drugs to ensure that patients receive the most appropriate treatment plan.

[0003] In medical testing, an oscillating mixer is a vital device that is widely used in the mixing and oscillating processes of samples. For example, before immunological, biochemical and other tests, it is often necessary to mix blood samples with anticoagulants or diluents. In the process of serum or plasma separation, an oscillating mixer can be used to promote blood coagulation or accelerate stratification during centrifugation. These applications reflect the importance and practicality of oscillating mixers in medical testing.

[0004] For example, a Chinese patent with publication number CN218609074U discloses an oscillating mixer for medical test samples, including a mixer body, a chassis and a stabilizing mechanism. The utility model combines the mixer body, the chassis and the stabilizing mechanism, which not only does not affect the oscillating mixing of medical test samples in sample tubes, but also can further support and protect the sample tubes, thereby reducing the probability of the sample tubes shaking, deviating or even detaching from the chassis due to external forces and affecting the inspection, thereby increasing the safety and stability of medical test sample detection work.

[0005] In actual use, current oscillating mixers need to oscillate test tubes, but the oscillation method is single and may not meet the mixing needs of all samples, resulting in unsatisfactory mixing effects. In addition, the single oscillation method may not ensure that the various components in the sample are fully and evenly mixed, thus affecting the accuracy and reliability of the experiment.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention, through the arrangement of the reciprocating rotating component and the reciprocating up and down component, allows the bearing chassis inside the circular fixed seat to rotate back and forth and oscillate up and down. The back and forth rotation can ensure that the sample is evenly distributed in the test tube along the horizontal direction, while the up and down knocking and vibration are helpful for the mixing of the sample in the vertical direction, further breaking the possible stratification or precipitation phenomenon, and ensuring that the sample is fully mixed in every corner of the test tube, thereby improving the mixing uniformity.

The present invention provides a rotatable top fixing plate and a bottom fixing plate in the bottom limiting plate and the top limiting plate on the bearing chassis, and then can perform clamping and fixing operations according to test tubes of different thicknesses, and can adapt to test tubes of various sizes. This means that in the medical examination process, there is no need to replace different mixing equipment for test tubes of different sizes. At the same time, the bottom limiting plate and the top limiting plate are both provided with the same top fixing plate and the bottom fixing plate, which can doubly clamp and fix the test tube, and can firmly clamp the test tube to prevent the test tube from falling off or breaking during the oscillation process.

[0022] 3. The present invention provides a movable limiting cylinder and a connecting rod between the bottom limiting plate and the top limiting plate. When an oscillation operation is required for a longer test tube, the gap between the bottom limiting plate and the top limiting plate can be quickly adjusted, so that test tubes of different lengths can be adapted for fixed oscillation operations. This flexibility not only saves time and resources, but also simplifies the experimental process, allowing experimenters to focus more on the experiment itself, while further improving the adaptability of the device.

[0056] Example 2

[0057] Reference Figure 1-12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the test tube fixing component 4 includes a limiting clamping hole 41 opened on the top of the bottom limiting disk 22 and the top limiting disk 23, and the hollow rotating column 42 passes through the bottom limiting disk 22 and the top limiting disk 23, the hollow rotating column 42 is rotatably connected to the inner wall of the limiting clamping hole 41, the top fixing disk 43 fixedly installed on the top of the hollow rotating column 42, the bottom fixing disk 44 fixedly installed on the bottom of the hollow rotating column 42, and a plurality of groups of fixed circular holes 45 arranged at the top edges of the top fixing disk 43 and the bottom fixing disk 44, and a limiting component 46 arranged on the hollow rotating column 42.

[0058] The limiting assembly 46 includes three groups of operating cavities 461 opened on the inner wall of the limiting card hole 41, three groups of limiting side plates 462 fixedly installed on the surface of the hollow rotating column 42, and the limiting side plates 462 extend to the inner cavity of the operating cavity 461, a first arc-shaped telescopic rod 463 fixedly installed at one end of the inner cavity of the operating cavity 461, a pushing block 464 fixedly installed at one end of the first arc-shaped telescopic rod 463 close to the limiting side plate 462, and a second spring 465 sleeved on the surface of the first arc-shaped telescopic rod 463.

[0059] The test tube fixing component 4 also includes a rotating handle 47 fixedly installed on the top of a group of top fixing plates 43. The setting of the rotating handle 47 facilitates the operation of rotating the top fixing plate 43 and the bottom fixing plate 44. A square hollow column 49 is fixedly installed on the top of the circular hole 27, and the square hollow column 49 passes through a group of hollow rotating columns 42, the top fixing plate 43 and the bottom fixing plate 44. A square sliding column 48 is fixedly installed on the bottom of another group of bottom fixing plates 44, and the bottom end of the square sliding column 48 slides and extends to the inner cavity of the square hollow column 49. Through the setting of the square sliding column 48 and the square hollow column 49, the top fixing plate 43 and the bottom fixing plate 44 on the top limiting plate 23 are rotated, which can synchronously drive the top fixing plate 43 and the bottom fixing plate 44 on the bottom limiting plate 22 to perform synchronous rotation operations.

[0060] During use, when it is necessary to place the test tube on the supporting base 21, first rotate the rotating handle 47 to drive the top fixed plate 43, the hollow rotating column 42 and the bottom fixed plate 44 on the top limiting plate 23 to rotate, and then use the sleeve of the square sliding column 48 and the square hollow column 49 to drive the top fixed plate 43, the hollow rotating column 42 and the bottom fixed plate 44 on the bottom limiting plate 22 to move synchronously with the rotating handle 47. When the rotating handle 47 rotates, the hollow rotating column 42 on the top fixed plate 43 and the bottom fixed plate 44 will rotate inside the limiting card holes 41 on the bottom limiting plate 22 and the top limiting plate 23, thereby causing the limiting side plate 462 on the hollow rotating column 42 to move inside the operating cavity 461, and then push the pushing block 464 to move, thereby causing the first arc-shaped telescopic rod 463 to contract and the second spring 465 to be compressed. When the hollow rotating column 42 rotates The top fixing plate 43 and the bottom fixing plate 44 are driven to move on the surfaces of the bottom limiting plate 22 and the top limiting plate 23 until the fixed circular holes 45 on the top fixing plate 43 and the bottom fixing plate 44 coincide with the limiting openings 24 on the bottom limiting plate 22 and the top limiting plate 23. Then the test tube can be passed through the fixed circular holes 45 and the limiting opening 24, and then until the bottom end of the test tube touches the inner cavity where the circular hole 27 is placed. At this time, the rotating handle 47 is released, and the rebound force of the second spring 465 can be used to drive the first arc-shaped telescopic rod 463 to extend, so that the pushing block 464 pushes the limiting side plate 462 to move in the inner cavity of the operating cavity 461, and then the hollow rotating column 42 is rotated to drive the top fixing plate 43 and the bottom fixing plate 44 to rotate and move, and then the fixed circular holes 45 on the top fixing plate 43 and the bottom fixing plate 44 are displaced and the test tube placed inside the limiting opening 24 is clamped and fixed.
