AI Technical Summary

Technical Problem

During the production of test cards, the desiccant bagging process is prone to omissions and overfills, which increases production costs and affects reagent performance. In addition, the existing packaging bags have large spaces, resulting in poor drying effect.

Method used

Design a test card including a main body, a cover and a sealing cap to form a sealed space with a built-in dehumidifier. The desiccant is located in the sealed space. The first opening is sealed by opening and closing the cover, which reduces the drying range, saves the amount of desiccant, and simplifies the assembly process.

Benefits of technology

It effectively limits the drying range, reduces drying costs, improves assembly efficiency, avoids desiccant leakage or overfilling, and ensures reagent performance stability.

Abstract

The invention provides a test card which comprises a main body part, a first sealing cover part, a cover body and a dehumidification part, the main body part is provided with a sample adding cavity and a detection cavity, the surface of the main body part is provided with a first opening and a second opening, the first opening is communicated with the sample adding cavity, and the second opening is communicated with the detection cavity; the cover body can seal the first opening in an opening and closing manner; the second opening is sealed by the first sealing cover piece; wherein at least the cover body, the first sealing cover piece and the main body piece jointly form a sealed space comprising a space in the sample adding cavity and a space in the detection cavity, all the spaces in the sealed space are communicated with one another, and the dehumidification piece is located in the sealed space. According to the test card provided by the invention, the cover body is designed to be openable and closable, so that a sample can be conveniently added into the sample adding cavity, and meanwhile, a sealed space can be formed for mounting a dehumidification part, so that the consumption of the dehumidification part is saved and the assembly efficiency is improved.
