Sample processing unit and sample analysis system

A sample analysis system comprising:

• the sample processing unit, comprising:
• a sample loading component;
• a transfer component;
• and
• an output component,
• wherein the sample loading component comprises a first feed bin, a second feed bin, a feeding mechanism and a flow limiting mechanism, the first feed bin comprises a bin bottom wall and a bin side wall connected to the bin bottom wall, a storage space is formed by the bin bottom wall and the bin side wall and configured to store sample containers received by the second feed bin and flowing from the second feed bin into the first feed bin, the feeding mechanism is connected to the first feed bin and configured to transport the sample containers in the storage space to the transfer component one by one;
• the transfer component is configured to receive a single sample container transported by the feeding mechanism, and transfer the single sample container to the output component;
• the output component is configured to receive the single sample container from the transfer component, and output the single sample container or at least one said single sample container carried on a sample carrying component;
• and
• wherein when the sample containers flow from the second feed bin into the first feed bin, the flow limiting mechanism is configured to limit a quantity of the sample containers flowing into the storage space, and the storage space is configured to be capable of storing a plurality of sample containers,
• a sample analysis unit, configured to analyze a sample in the single sample container;
• and
• a transmission unit, connected to the sample processing unit and the sample analysis unit, and configured to transport the single sample container or the sample carrying component output from the sample processing unit to the sample analysis unit.
