AI Technical Summary

Technical Problem

Existing HIV and TP antibody combined detection products are cumbersome to operate, prone to errors, and structurally unstable, making them difficult to interpret accurately in non-laboratory environments. They also have limited sample compatibility and cannot be compatible with whole blood or fingertip capillary blood samples.

Method used

Design a vertical dual-unit detection device with self-priming sampling capability. It adopts a vertical columnar structure and a mounting frame with double-sided mounting slots. Combined with buffer tubes and capillary tubes for flow guidance, it can achieve simultaneous detection in one sampling. It uses double-sided partitioned display of results, is compatible with multiple sample types, and ensures stability through snap-fit ​​and connectors.

Benefits of technology

It simplifies the operation process, improves detection efficiency and accuracy, ensures clear result interpretation, adapts to various sample types, enhances the stability and biosafety of the device, and reduces production costs.

Abstract

This utility model discloses a vertical dual-mode detection device with self-absorption sampling capability, relating to the field of material analysis by determining the chemical properties of materials. It includes a sampling component and a storage component. The sampling component comprises a detection tube and a mounting frame. The mounting frame has mounting slots on both the front and back for mounting chromatographic test strips. The sampling end of the detection tube has a buffer tube and a capillary tube. An extension at one end of the mounting frame is inserted into the buffer tube, so that the sample application ends of the two chromatographic test strips are located inside the buffer tube. The storage component includes a storage tube, a base, and a seal. In use, after the sample is aspirated through the capillary tube, the sampling component is inserted into the storage component. The diluent and sample mix, and the mixture is evenly distributed to the dual-mode test strips through the buffer tube, achieving simultaneous detection of two items in a single sampling. This utility model is easy to assemble, provides simultaneous dual-mode chromatography, offers intuitive interpretation, and has high detection efficiency and accuracy.
