Description

Technical Field

[0001] The invention relates to the field of immunoassay, and in particular to a sample rack single-track conveying device. Background Art

[0002] Chemiluminescence detector combines highly sensitive chemiluminescence measurement technology with highly specific immune response. It is used for the detection and analysis of various antigens, antibodies, hormones and drugs. It is the latest immunoassay technology developed after radioimmunoassay, enzyme immunoassay and fluorescence immunoassay.

[0003] Most of the existing flow fluorescence detection instruments only have result analysis modules, and the front-end processing is mostly completed by manual operation. The process of adding samples and reagents needs to be completed manually. After adding the samples, the samples need to be incubated and cleaned. This process needs to be repeated at least 2-3 times to complete the front-end processing of one sample. The processed sample is then placed on the detection instrument for result analysis. This operation method is not only labor-intensive but also has low detection efficiency, and is not suitable for detection when the number of samples is large.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0009] When it is necessary to add samples, the sample rack is first placed on the loading mechanism, and the pusher drive assembly arranged on the loading mechanism pushes the pusher assembly to drive the sample rack to move until it is pushed to the sample delivery assembly, and the sample delivery drive assembly drives the sample rack to move to the sampling position. After the detection module completes the sample aspiration, the sample delivery drive assembly returns the sample rack to its original position, and then the recovery drive assembly drives the sample rack to move to the recovery mechanism;

[0010] In this way, the addition of samples is completed, and the above-mentioned automated work process replaces manual addition, thereby greatly improving work efficiency. It is more suitable for testing when the number of samples is large, and no manual operation is required, reducing the workload of staff.

The sample rack moves forward on the slide under the push of the pusher drive assembly. The sample rack is T-shaped as a whole, and the two sides of the sample rack abut against the surface and side of the slide, so that the sample rack will not fall down during the pushing process.

[0020] The sample rack is pushed to the sample delivery mechanism by the pusher. First, the sample delivery slide will move between the loading platform and the recovery platform on the sample delivery rod under the drive of the sample delivery drive component. The sample rack will move to the sample delivery slide under the action of the pusher.

[0034] Preferably, a placement groove is provided on the side surface of the recovery push plate, and a sensor is provided in the placement groove.

[0035] In this way, when the recovery push plate pushes the sample rack, the position to which it moves is specified by the sensor.

[0036] In summary,
