[0030] Most of the existing rotary mixing devices mix and stir biological samples by means of rotation, vibration, etc. However, the structures of the existing rotary mixing devices are usually relatively complex and the manufacturing costs are relatively high. Therefore, a rotary mixing device that can achieve the mixing function and has a simple structure and low manufacturing cost is needed.

[0031] In view of this, the present application provides a rotary mixing device for biological samples, including: a support base 1, a driving motor 6 is installed on the support base 1, a rotating disk 8 is installed on the output shaft of the driving motor 6, and a plurality of mounting holes 801 are formed in the rotating disk 8 for inserting and clamping a sample tube 10.

[0032] In the first embodiment of a rotary mixing device for biological samples of the present application, referring to Figures 1 to 2 , it includes a support base 1. The support base 1 is an L-shaped structure made of a metal material, specifically, materials such as copper and iron. The support base 1 plays the roles of counterweight and support. The two mutually perpendicular surfaces protruding from the support base 1 are respectively a first surface and a second surface. An L-shaped backing plate 2 is pasted on the first surface and the second surface of the support base 1. The backing plate 2 is a structure made of a rubber material and is used to contact the contact surface (tabletop or ground), which can increase the friction between the support base 1 and the contact surface. The backing plate 2 cooperates with the weight of the support base 1 itself to prevent the device from displacing itself during use.

[0033] Referring toFigure 1 The third side of the concave part of the support base 1 faces the first side, and the fourth side of the concave part of the support base 1 faces the second side. A triangular support frame 3 is arranged between the third side and the fourth side of the support base 1. Two of the corners of the support frame 3 are fixedly connected to the third side and the fourth side of the support base 1 respectively by screws. An annular mounting ring 4 is arranged at a position on the support frame 3 far from the third side and the fourth side of the support base 1. The mounting ring 4 is welded to the support frame 3. The axis of the mounting ring 4 is perpendicular to the third side of the support base 1. A fastening screw 5 perpendicular to the axis of the mounting ring 4 is arranged on the side surface of the mounting ring 4. The fastening screw 5 penetrates into the mounting ring 4 and is threadedly connected to the mounting ring 4.

[0034] Reference Figure 1 and Figure 5 A driving motor 6 is arranged in the mounting ring 4. The fastening screw 5 is used to press and fix the driving motor 6 in the mounting ring 4. A control switch is connected to the power line of the driving motor 6. The start, stop, forward and reverse rotation and speed of the driving motor 6 can be controlled through the control switch. A runner 7 is fixedly connected to the output shaft of the driving motor 6. An annular rotating disk 8 is sleeved outside the runner 7. The rotating disk 8 is fixedly connected to the runner 7. A plurality of mounting holes 801 are circumferentially and evenly arranged on the end surface of the rotating disk 8. The rotating disk 8 is made of an elastic soft material, specifically, it can be made of materials such as foam, rubber, latex, etc., so that the mounting holes 801 are elastic. The mounting holes 801 can clamp the sample tube 10 inserted therein through their own elasticity. The sample tube 10 is a tubular container filled with a biological sample, specifically, it can be an EP tube, and it is sealed with a stopper or a sealing film during stirring.

[0035] Reference Figure 1 and Figure 2 The fifth side of the support base 1 is located between the first side and the third side. The fifth side of the support base 1 is parallel to the fourth side. A handle 9 is fixedly installed on the fifth side of the support base 1. The handle 9 is used for carrying the device by hand. At the same time, the user can turn the device 90° through the handle 9. As Figure 2 shown, the axis of the rotating disk 8 is perpendicular to the horizontal line. At this time, the stirring tube 10 containing a small amount of biological sample can be stirred without sealing, so that the device can be applicable to the stirring of materials in various situations.

[0037] Reference Figure 3 and Figure 4, different from the first embodiment in that: the rotating disk 8 is made of a hard material, specifically, materials such as aluminum alloy and plastic. A plurality of spring pieces 802 are circumferentially and uniformly arranged around the mounting hole 801 near the mounting hole 801 on the rotating disk 8. The number of the spring pieces 802 is at least three. The spring pieces 802 are used to automatically clamp the sample tube 10 inserted into the mounting hole 801. Three or more spring pieces 802 make the installation of the sample tube 10 more stable.

[0038] In the technical solution of the present application, a driving motor is installed on the support base, a rotating disk is installed on the driving motor, and a plurality of mounting holes are provided on the rotating disk. The mounting holes can automatically clamp the sample tubes inserted therein. When the driving motor is started, the rotating disk will drive the sample tubes to rotate, and the biological samples in the sample tubes can be mixed under the action of centrifugal force; by installing a plurality of sample tubes on the rotating disk, a plurality of different types of biological samples can be mixed simultaneously. After the mixing is completed, the sample tubes are removed and other sample tubes are installed, and then different types of biological samples can be mixed subsequently. Each different type of biological sample is isolated from each other, and cross-contamination between biological samples during the mixing process can be avoided; the design of the mounting holes can automatically clamp and fix the sample tubes inserted therein, and the disassembly and installation are relatively convenient, and the structure is simple and the manufacturing cost is low.
