[0032] Example 2

[0033] See also Figure 4 As shown, in contrast to Example 1, as another embodiment of the present invention, a second auxiliary rotating component 3 is provided on the surface of the fixed porous frame 254, and the second auxiliary rotating component 3 includes a rotating track 31, a second auxiliary ball 32 and a second auxiliary slide 33. The surface of the fixed porous frame 254 is provided with a rotating track 31, and the inner side of the rotating track 31 is provided with a second auxiliary ball 32.

[0034] Working principle: First, a medical blood auxiliary mixing device is moved to the working position. When in use, the operator first ensures that the device is in the closed state and checks whether all components are intact. The protective cover 212 is opened by the handle 213 to expose the internal placement component 24. The blood sample tube or other container to be mixed is placed in the silicone placement hole 244. The silicone material helps to fix test tubes of different sizes and prevent them from shifting during rotation. When the position of the porous rack needs to be adjusted to place more samples or accommodate test tubes of different sizes, it can be By moving the slider 252 along the sliding track 251, the position of the outer ring 253 and its fixed porous frame 254 is adjusted. In the second step, it is confirmed that all the test tubes have been correctly and firmly placed in the silicone placement hole 244, and the protective cover 212 is closed. The protective cover 212 is safely locked in place using the rotating shaft 211 to prevent accidental contact or dust from entering during operation. The drive motor 221 is turned on, and the motor drives the main gear 223 to rotate through the drive shaft 222. The main gear 223 further drives the driven gear 224 and the outer gear ring 226 to operate, thereby achieving deceleration and torque increase. The effect is achieved. Since the placement rack 243 is connected to the driven gear 224 via the connecting shaft 245, the entire placement rack 243 begins to rotate at a preset speed and direction. The first auxiliary ball 231 and the first auxiliary slide 232 in the first auxiliary rotating assembly 23 help reduce friction and ensure the smooth operation of the planetary gear assembly 22. The second auxiliary rotating assembly 3 allows the placement rack 243 to rotate additionally in another dimension, enhancing the mixing effect. In the third step, according to the set time parameters, the placement rack 243 continues to rotate so that the blood sample in the test tube is evenly and thoroughly mixed. For samples containing cells, plasma or other components, an appropriate mixing time is crucial to ensure that the components can be fully integrated without damaging sensitive substances. When the predetermined mixing time expires, the drive motor 221 is turned off, and the device gradually stops operating. The handle 213 is used again to open the protective cover 212, and the mixed blood sample tube is carefully removed from the silicone placement hole 244. The equipment is cleaned and maintained to prepare for the next use. This completes the use process of a medical blood auxiliary mixing device.
