Sample rack transport apparatus, sample analysis device, and sample analysis system

A sample analysis system, comprising:

• a first sample analyzer, a second sample analyzer, a first sample rack transport apparatus, and a second sample rack transport apparatus;
• wherein the first sample rack transport apparatus and the second sample rack transport apparatus are adjacently configured to transport a sample rack;
• the first sample rack transport apparatus comprises:
• a first bidirectional transfer track configured to bidirectionally transfer the sample rack without passing through the first sample analyzer;
• a first feed channel, in parallel with the first bidirectional transfer track and arranged opposite to the bidirectional transfer track along a direction perpendicular to an extending direction of the bidirectional transfer track, wherein the sample rack is capable of being delivered from the first bidirectional transfer track to the first feed channel and to the first sample analyzer;
• a first unloading buffer region located between the first bidirectional transfer track and the first feed channel, wherein the first unloading buffer region is configured to store the sample rack;
• a first unloading mechanism configured to deliver the sample rack in the first feed channel to the first unloading buffer region for storing the sample rack or deliver the sample rack stored in the first unloading buffer region to the first bidirectional transfer track;
• a first loading buffer region located between the first bidirectional transfer track and the first feed channel, wherein the first loading buffer region is configured to store the sample rack;
• and
• a first loading mechanism configured to deliver the sample rack to the first loading buffer region for storing the sample rack or deliver the sample rack stored in the first loading buffer region to the feed channel;
• wherein the first unloading buffer region is arranged separately from the first loading buffer region, and the first unloading buffer region, the first bidirectional transfer track and the first loading buffer region form a U-shaped structure;
• and
• the second sample rack transport apparatus comprises:
• a second bidirectional transfer track configured to bidirectionally transfer the sample rack without passing through the second sample analyzer;
• a second feed channel, in parallel with the second bidirectional transfer track, wherein the sample rack is capable of being delivered from the second bidirectional transfer track to the second feed channel and to the second sample analyzer;
• a second unloading buffer region located between the second bidirectional transfer track and the second feed channel, wherein the second unloading buffer region is configured to store the sample rack;
• a second unloading mechanism configured to deliver the sample rack in the second feed channel to the second unloading buffer region for storage or deliver the sample rack stored in the second unloading buffer region to the second bidirectional transfer track;
• a second loading buffer region located between the second bidirectional transfer track and the second feed channel, wherein the second loading buffer region is configured to store the sample rack;
• and
• a second loading mechanism configured to deliver the sample rack to the second loading buffer region for storing the sample rack or deliver the sample rack stored in the second loading buffer region to the second feed channel;
• wherein
• the second unloading buffer region is arranged separately from the second loading buffer region, and the second unloading buffer region, the second bidirectional transfer track and the second loading buffer region form a U-shaped structure;
• and
• the first sample rack transport apparatus and the second sample rack transport apparatus are adjacently configured to use the first bidirectional transfer track and the second bidirectional transfer track to transport the sample rack.
