[0002] Biological samples generally refer to partial tissues or body fluids of plants or animals, as well as microorganisms such as tissue trachea. In the determination of biological samples, depending on the different determination items, they must first undergo digestion and incineration, or extraction and separation, and then the content of the components to be tested can be determined. Before the biological sample detection experiment, the collected body fluids and other liquids need to be mixed to provide preparation for sample preparation.

[0003] Since the biological samples collected in the laboratory are of low weight, it is difficult to use larger mixing equipment to mix the biological samples, which increases the difficulty of mixing. In addition, the existing mixed samples are mixed by a stirring shaft. As the biological samples heat up as the stirring shaft rotates at a high speed, they are easily adhered to the surface of the stirring shaft, which increases the difficulty of cleaning. In addition, the traditional mechanical stirring method is prone to deformation of the stirring shaft after long-term use, causing the stirring plate to fall off and affecting the stirring process.

Figure 4 As shown, the one-way valve 12 is connected to the communication ring 11, so that the gas inside the communication ring 11 can be blown into the biological sample, thereby facilitating the mixing of the biological sample.

[0036] Working principle: When using the shaftless biological sample mixing device, the biological sample liquid is pushed into the mixing cylinder 1, and after the top of the mixing cylinder 1 is snap-connected with the cover plate 3, the gas of the compression pump is input into the air inlet port 5, so that the gas entering the air inlet port 5 is scraped and poured into the ventilation pipe 7, and sprayed to the outside through the one-way discharge pipe 8, pressing the liquid inside the mixing cylinder 1, and the biological samples are turned and mixed under the impact of the gas, and the air is supplemented into the connecting ring 11 through the air hole 10 at the bottom of the ventilation pipe 7, so that the one-way valve 12 sprays gas upward, which is convenient for impacting the biological sample liquid, so that the biological samples are quickly mixed and processed.
