Description

Technical Field

[0001] The utility model relates to the technical field of sample separation equipment, in particular to a sample separation device. Background Art

[0002] The biggest feature of the rapid test kit is that it is easy and fast to operate while ensuring specificity, and the results are objective. During use, the collected samples are made into liquid reagents and then added to the kit for testing. When testing human tissue or blood, the collected samples need to be separated first, and the samples to be tested are obtained after separation. The collected samples are added to sample tubes for separation to make tissue fluid. The collected samples are added to sample tubes, and the sampling stick is rotated in the sample tube to accelerate the dissolution of the samples into the separation liquid before the rapid test kit can be used for testing.

[0003] However, the sampling rod of the separation sample tube is inserted into the separation liquid, and the sample on the sampling rod is made to fall into the separation liquid by shaking. However, simple shaking cannot ensure that the sample on the sampling rod is completely integrated into the separation liquid, which affects the sample concentration in the separation liquid and is not conducive to the accuracy of subsequent sample detection.
