Description

Technical Field

[0001] This utility model relates to the field of sample testing technology, and in particular to a sample mixing device. Background Technology

[0002] Sample tubes are a crucial part of laboratory analysis, playing a central role in numerous fields such as biology, chemistry, medical diagnostics, environmental protection, and food safety. They are primarily used to collect, store, and transport various liquid samples, such as blood, urine, tissue homogenates, cell culture media, and chemical reagents awaiting testing. In many analytical tests, sample pretreatment steps are critical to the accuracy and reliability of the final results. Among these, sample mixing is key to ensuring sample homogeneity and preventing component sedimentation, stratification, or localized concentration imbalances. Currently, common sample tubes include blood collection tubes (such as vacuum blood collection tubes), centrifuge tubes, and cryopreservation tubes. These are typically inert containers without active mixing capabilities. When samples contain solid particles (such as blood cells) requiring uniform dispersion, precipitates, or need to be thoroughly mixed with pre-prepared additives (such as anticoagulants, stabilizers, preservatives, lysis buffers, etc.), manual shaking is usually used for mixing.

[0003] Manual shaking is the simplest and most common mixing method, where the operator shakes or inverts the sample tube to mix the sample thoroughly. However, manual mixing often presents the following problems in practice. First, the mixing effect is unstable; the force, frequency, and time of manual mixing are difficult to control, and the mixing effect varies greatly between different operators, resulting in poor reproducibility of experimental results. Second, manual mixing is labor-intensive; for experiments requiring the processing of large numbers of samples, manual mixing increases the operator's workload and can easily lead to fatigue. Third, manual mixing poses safety hazards; during manual mixing, samples are prone to splashing or leaking, potentially causing contamination or injury to the operator, especially when handling toxic, harmful, or infectious samples.

[0004] Although mixing methods such as manual flipping, external oscillation, or magnetic stirring are used in some scenarios, additional equipment and operating steps are still required. It is difficult to achieve efficient and uniform mixing without compromising the sealing and sterility, especially for high-viscosity liquids, suspended particulate samples, and powder samples, where the mixing effect is often limited.

[0005] Existing technologies also include some mixing devices that can mix samples in batches. Usually, vortex mixing is required in a special container. However, batch mixing often involves sample transfer. Samples need to be transferred, and they cannot be mixed immediately, which would affect the experimental results. Sometimes, samples need to be transferred to a specific mixing container, which increases the number of operation steps and the risk of contamination, as well as the workload of the mixing operation.

[0006] However, the sample tube has a relatively simple structure and lacks a built-in shaking function. Therefore, before staff can use the sample in the sample tube, they must manually shake it. This process not only wastes the staff's valuable time but also adds to their workload.

[0007] There are no effective solutions yet for the problems existing in the related technologies, such as unstable mixing effect of manual sample mixing, inability to mix directly in the sample tube, and low sample mixing efficiency. Utility Model Content

[0146] The method of using this utility model is as follows:

[0147] After the inner tube element 201 has been sampled and sealed, it is placed vertically inside the outer tube element 101. The first transmission element 202 and the second transmission element 302 are engaged. The top of the first rotating ring element 104 supports the first transmission element 202. The sample information is recorded on the label element 106. The power element 401 is activated, which drives the fourth transmission element 402 to rotate. The fourth transmission element 402 drives the third transmission element 303 to rotate. The second transmission element 302 and the third rotating ring element 301 rotate together, and drive the first transmission element 202 to rotate, which in turn drives the inner tube element 201 to rotate.

[0149] The technical effects of this utility model are as follows:

[0150] An inner tube unit is nested within an outer tube unit and rotatably connected to it. A transmission unit engages with the inner tube unit via gears, and under the action of a power unit, the inner tube unit rotates relative to the outer tube unit, thereby mixing the sample in the inner tube unit. This allows for automatic and direct mixing of samples in the sample tube, simplifying operation, saving labor, and solving the problem of not being able to directly mix samples within the sample tube. Furthermore, the mixing time and speed can be determined based on the characteristics of the sample, ensuring the consistency and stability of sample mixing intensity without transferring the sample, greatly improving sample mixing efficiency and solving the problems of unstable mixing effect and low sample mixing efficiency in manual mixing.

[0237] The usage method of this embodiment is as follows:

[0238] Using the method of Embodiment 1, the inner tube element 201 is placed inside the outer tube element 101. Then, the third limiting element 602 is connected to the corresponding second limiting element 203 for limiting. The third sealing element 701 is placed over the top of the first sealing element 501, and the side of the third sealing element 701 is engaged with the side element. The third sealing element 701 is pressed so that its bottom end abuts against the first sealing element 501. Under the action of the third sealing element 701, the first locking element 506 first slides along the through element 503 toward the first limiting element 504, and the reset element 508 is compressed. When the fixed element 506 enters the through element 503, and the third sealing element 701 is fully in contact with the first sealing element 501, the second locking element 702 is connected to the through element 503, the reset element 508 returns to its original shape, the second locking element 702 is locked to the corresponding first locking element 506, and drives the movable element 505 to slide along the through element 503 toward the first locking element 506. The fifth limiting element 703 is limited to the fourth limiting element 604, and the relative positions of the third sealing element 701 with the first sealing element 501 and the second sealing element 601 are locked.

[0239] When mixing samples, the operation is the same as in Example 1. The inner tube element 201 rotates relative to the outer tube element 101, which drives the second sealing element 601 to rotate. The rotating element 603 rotates, while the first sealing element 501, the second sealing element 601, and the third sealing element 701 remain stationary.

[0240] Once mixing is complete, pull the control element 507 to drive the movable element 505 and the first locking element 506 to slide along the through element 503. The reset element 508 is compressed, the first locking element 506 enters the through element 503, and the connection with the second locking element 702 is released. The third sealing element 701 is removed, and then the second sealing element 601 is removed. The connection between the third limiting element 602 and the second limiting element 203 is released, and the inner tube element 201 can be taken out.

[0241] The technical effects of this embodiment are as follows:

[0242] The first capping unit covers the top of the outer tube unit and is connected to the inner tube unit for limiting, which can effectively protect the transmission unit and the power unit. The first capping unit and the third capping unit are detachably locked together, and the third capping unit is connected to the second capping unit for limiting, which can fix the inner tube unit at the top. This not only makes the operation simple, but also ensures the stability of the inner tube unit during the mixing process, prevents the inner tube unit from separating from the outer tube unit under high-speed rotation, and does not affect the rotation of the inner tube unit to mix the sample.

[0243] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
