[0002] With the continuous improvement of medical detection requirements, a biochemical and immunological online system has gradually become an indispensable part of modern laboratories. The system connects a biochemical analyzer and a chemiluminescence immunoassay analyzer to realize high automation of a sample processing process, and significantly improves work efficiency and detection accuracy. When transporting a sample rack, the biochemical and immunological online system needs to move quickly and stop orderly to realize track switching between a biochemical analyzer track and a chemiluminescence immunoassay analyzer track. In order to realize this, a blocking device is usually used to control the parking position of the sample rack. However, the existing blocking device is directly installed outside the biochemical analyzer track or the chemiluminescence immunoassay analyzer track. During blocking of the sample rack, the sample rack will collide and cause splashing of samples. Alternatively, the speed needs to be reduced to realize blocking. Meanwhile, the blocking device protrudes outside the track, so that the length of the biochemical and immunological online system changes with the structure of the blocking device, which is not beautiful and affects the layout of the laboratory.

[0022] With the continuous improvement of medical detection needs, biochemical immuno online systems have gradually become an indispensable part of modern laboratories. By connecting biochemical analyzers and chemiluminescence immunoassay analyzers, the system realizes high automation of the sample processing process, significantly improves work efficiency and detection accuracy. When transporting the sample rack, the biochemical immuno online system needs to move quickly and stop in order to realize the track switching between the biochemical analyzer track and the chemiluminescence immunoassay analyzer track. In order to achieve this, a blocking device is usually used to control the parking position of the sample rack. However, the existing blocking device is directly installed outside the biochemical analyzer track or the chemiluminescence immunoassay analyzer track. In the process of blocking the sample rack, the sample rack will collide and cause the sample to splash; or the speed needs to be reduced to achieve blocking; at the same time, the blocking device protrudes outside the track, so that the length of the biochemical immuno online system will change with the structure of the blocking device, which is not beautiful and will affect the layout of the laboratory.

[0023] Based on this, the exemplary embodiments of the present application provide a blocking device for biochemical immuno online system track, which is arranged between the biochemical analyzer track and the chemiluminescence immunoassay analyzer track, does not protrude outside the track, and can ensure the length stability of the biochemical immuno online system; by arranging a driving unit, a gear, a rack, a guide assembly and a blocking plate, the driving unit can drive the gear to rotate, and then drive the rack to slide on the guide assembly, so as to realize the lifting of the blocking plate; when the sample rack needs to be blocked, the blocking plate is driven to rise, and the sample rack is conveyed from the chemiluminescence immunoassay analyzer track to the biochemical analyzer track; when the sample rack needs to be released, the blocking plate is driven to descend, and the sample rack is released, so that the cross-track track switching conveying of the sample rack can be realized; the sample rack does not need to be lowered in speed to realize accurate blocking or releasing, and collision of the sample rack can be avoided, so that sample splashing can be avoided.

[0024] The exemplary embodiments of the present application provide a blocking device for biochemical immuno online system track, as shown in Figure 5 The blocking device is arranged between the biochemical analyzer track (not shown in the figure) and the chemiluminescence immunoassay analyzer track 10, and the biochemical analyzer track is located Figure 5 The other side of the blocking device, and the blocking device only has the blocking plate 1056 extending out of the chemiluminescence immunoassay analyzer track 10, and other parts are arranged below the chemiluminescence immunoassay analyzer track 10, so that the gap between the chemiluminescence immunoassay analyzer track 10 and the biochemical analyzer track is small, and the sample rack 100 can be smoothly switched between the two; at the same time, the blocking device does not protrude outside the track, and can ensure the length stability of the biochemical immuno online system.
