Background

Blood is the most commonly used sample in medical testing. Many modern fully automated analytical instruments have been developed based on the detection of blood samples. Such as a full-automatic fluorescence immunoassay quantitative analyzer, a full-automatic gold-labeled analyzer, a chemiluminescence immunoassay analyzer, a full-automatic biochemical analyzer and the like. In an analysis instrument using a blood sample, such as a full-automatic fluorescence immunoassay quantitative analyzer and a full-automatic gold-labeled analyzer, the blood sample is mixed with a relevant reagent and a buffer solution, and then a reaction result after mixing is detected and analyzed. Finally outputting the information needed by doctors and patients.

Typically, blood samples are stored in different blood collection tubes. The blood sampling tube is covered with a cap for preventing blood from overflowing. After the blood sampling tube is placed in the instrument, the instrument can absorb a certain amount of blood samples from the blood sampling tube once or for multiple times according to different test item requirements. Before quantitatively sucking up the sample, some samples need to be mixed by shaking the blood collection tube. After shaking up, if the TIP is used to insert into the tube to suck up the sample, the cap of the blood collection tube needs to be removed in advance. After the instrument is used for sampling, the blood sample in the blood collection tube may need to be left for use or discarded, and the cap of the blood collection tube needs to be covered again to prevent pollution.
