Description

Technical Field

[0001] This utility model relates to the technical field of support equipment for test reagent sample cups / tubes, and in particular to a protective device for test reagent sample cups / tubes. Background Technology

[0002] In automated medical testing, large quantities of serum or plasma samples are often processed. These samples are typically aliquoted from original sampling tubes by third-party medical testing institutions. Due to the different tests submitted by clients, serum or plasma may need to be sent to different departments for testing. Automated testing equipment in these departments has strict requirements on sample quality and volume. When the sample volume is insufficient or contains fibrin, the equipment may not be able to draw enough sample for testing, causing an alarm and requiring refilling or requesting the client to provide a new sample. This process not only wastes reagents and time but may also cause patient dissatisfaction.

[0003] To avoid the aforementioned problems, serum or plasma samples with insufficient volume or unsuitable collection containers are typically transferred to reaction cups or 1.5ml centrifuge tubes before being processed. However, currently these reaction cups or centrifuge tubes are stored in plastic containers at room temperature, which has the following drawbacks: (1) In fast-paced work environments such as night shifts, sample caps may fall off or serum may leak or splash during sample processing (such as aspiration, addition, cap removal, centrifugation, shelving, removal, and dilution). If these contaminants fall into the plastic container, they may contaminate the reaction cup and centrifuge tube, thereby affecting the accuracy of the test results and leading to clinical misjudgment.

[0004] (2) Because the detection equipment is very precise, the exposed reaction cups and centrifuge tubes are easily contaminated by dust, paper scraps and other small substances, which may affect the aspiration effect of the sample needle, thereby affecting the reaction process, resulting in reagent waste and inaccurate detection results.

[0005] (3) The scattered reaction cups and centrifuge tubes are inconvenient to pick up, which wastes time and reduces work efficiency. Utility Model Content
