Description

Technical Field

[0001] The utility model relates to the technical field of biomedical experimental equipment, in particular to a vortex instrument auxiliary positioning device. Background Art

[0002] In the process of biomedical experiments, a vortex instrument is indispensable as a mixing instrument for experimental samples. In the existing shaking operation, it is necessary to place the container with the sample on the vibrating head with a flexible pad of the vortex instrument, and hold the container by hand to make it slightly pressed on the vibrating head, and then turn on the vortex instrument to perform the shaking process. During the shaking process, the container needs to be kept stable. While ensuring that the rotation and vibration of the vibrating head are fully transmitted to the container, the container must also be kept stable to prevent the container from falling or being broken by excessive vibration. The shaking operation process is too laborious and requires long-term manual operation. In the process of pressing the container on the vibrating head by manpower, it is inevitable that the shaking effect will be slightly deviated due to the long operation time or the different strengths of different personnel, which can easily affect the experimental results. Therefore, there is an urgent need for an auxiliary equipment to replace the process of manually pressing the container with the sample on the vortex instrument.

[0003] The existing Chinese patent authorization announcement number CN208213038U is authorized on December 11, 2018, and the vortex mixer bracket and mixing system, wherein the vortex mixer bracket includes: a fixed part and a limit part arranged on the top of the fixed part; the fixed part is used to be fixedly connected to the fuselage of the vortex mixer; the limit part is also formed with a receiving space for accommodating reagent bottles to limit the vibration range of the reagent bottles on the work surface. The vortex mixer bracket and mixing system provided in this embodiment, when shaking, the reagent bottle can be placed in the receiving space on the top of the work surface, when the work surface rotates and vibrates, the reagent bottle can be driven to shake, and the limit part can limit the vibration range of the reagent bottle on the work surface, preventing the reagent bottle from falling off the work surface, thereby achieving the oil product shaking, no hand support, easy operation; and, because the capacity of the reagent bottle is much larger than the capacity of the test tube, the volume of oil that can be shaken in one operation is large, and the shaking efficiency is high.

[0004] However, the shapes of the limiting part and the fixing part are fixed, that is, the same auxiliary positioning device can only be adapted to reagent bottles of one shape. In the process of various types of biomedical experiments, the vortex mixer needs to be shaken for reagent bottles of different sizes and types. Therefore, the vortex mixer bracket cannot be directly used to replace the manual shaking operation in biomedical experiments. Utility Model Content
