Problems solved by technology

However, after returning to the sample placement area, the sample racks for automatic retesting are ranked after other routine samples in the sample placement area, and have the lowest priority, while the automatic retesting of some emergency samples requires a higher priority, and Some tests, retested after a longer period of time, can affect the accuracy of test results
Therefore, this mode has only one priority, which cannot meet the high priority requirements of automatic retesting of some samples

Embodiment 1

[0024] Please refer to figure 1 , the sample rack transfer system includes a sample carrying device 1 and a driving mechanism (not shown in the figure). The sample carrying device 1 is used to carry a sample rack, and includes a sample input area 4 , a sample outlet 6 , a sample rack pushing mechanism 2 and a sample rack pushing back mechanism 7 . The sample outlet 6 is located at the first end of the sample insertion area 4 . The sample rack propulsion mechanism 2 is coupled with the driving mechanism, and is used to push the sample rack 3 from the sample insertion area 4 to the direction of the sample outlet 6 driven by the driving mechanism, so that the sample rack 3 reaches the sample suction position for execution Aspirating operation, so the initial position of the sample rack propulsion mechanism 2 is set above the side of the sample insertion area 4, for example, the initial position of the sample rack advancement mechanism 2 is set at the side of the sample insertion...

Embodiment 2

[0027] like figure 1 As shown, on the basis of Embodiment 1, the sample rack transfer system can further include a priority change control key 9 as an emergency button, and can also include a run key 8, when the priority change control key is triggered (for example, pressed or rotated) or toggle), a trigger signal is generated, and the driving mechanism responds to the trigger signal and drives the sample rack pushback mechanism to move from the outside of the sample outlet to the direction of the sample insertion area. The running key 8 is used to control the driving mechanism to drive the sample rack propulsion mechanism 2 to move.

[0028] The emergency button is arranged on the sample rack transmission system. When the user needs to treat the emergency sample first, press the emergency button first, and the sample rack already in the sample insertion area will be moved back through the sample rack push-back mechanism, and back out of the emergency insertion area. Insertin...

Embodiment 3

[0030] Please refer to Figure 2-4 . like figure 2 As shown, the sample rack delivery system includes a sample carrying device 1 , a driving mechanism (not shown in the figure), a sample retest buffer device 11 and a retest sample delivery device (not shown in the figure). The sample carrying device 1 is located upstream of the sample suction position 15, and the sample retest buffer device 11 is located downstream of the sample suction position 15. The sample retest buffer device 11 is used to store the sample racks that have been tested and are waiting for the test results, and the retest The sample delivery device is located downstream of the sample retest buffer device 11, and is coupled with the driving mechanism, and is used to transport the sample rack that has obtained the test result from the retest outlet to the sample rack that is located at the sample insertion port under the drive of the drive mechanism. The retest inlet at the second end of the zone or the inl...

Abstract

The invention discloses a sample rack delivery system and a biochemical analyzer. The sample rack delivery system comprises a sample carrying device and a driving mechanism. The sample carrying device includes a sample rack advancing mechanism and a sample rack retreating mechanism, the initial position of which is located over the side of a sample outlet and coupled with the driving mechanism. Driven by the driving mechanism, the sample rack retreating mechanism moves a predetermined distance towards a sample releasing area from the outside of the sample outlet, and the predetermined distance is at least greater than the width of one sample rack. According to the invention, the test sequence of sample racks can be altered by the sample rack retreating mechanism. Specifically, a sample rack in urgent need of testing can be delivered to a sample uptaking position in priority during a routine test and an automatic retest. Thus, the testing priority of sample racks is altered.

Description

technical field [0001] The invention relates to a biochemical analyzer, in particular to a sample rack transmission system in the biochemical analyzer. Background technique [0002] A biochemical analyzer can be used to analyze multiple samples, and the samples are usually tested in a first-in-first-out order. But sometimes there will be an emergency situation, and the biochemical analyzer is required to test the emergency samples first. This requires the sample transfer system of the biochemical analyzer to change the priority order of the test, and give priority to the emergency sample to the sample test position. In addition, after the test is completed, some samples fail to pass the test and need to be retested, and there are also samples that need to be tested first among the retested samples. [0003] At present, there are rotating disk methods and U-shaped buffer path methods in the sample rack transfer technology. 1) Rotating disk mode: The sample rack is sent to ...
