Description

Detection reagent rod with buffer solution

Technical Field

The utility model relates to the technical field of medical consumables, in particular to a detection reagent rod with a buffer solution.

Background

The identification of respiratory infectious diseases requires nucleic acid detection, which is roughly divided into two steps: 1) collecting a patient sample; 2) and detecting the center. The sample collection work of the first step has higher requirement on the collected position, and the sample must reach the pharyngeal posterior wall or tonsil part, otherwise, the detection accuracy is influenced. A doctor will typically prepare a reagent stick (pharyngeal swab) similar to a long cotton swab and a reagent tube. The patient should take off the mask and then open his mouth to make an "o" sound, so that the posterior pharyngeal wall is exposed. At this time, the doctor extended the reagent stick to the posterior pharyngeal wall of the patient and smeared to take a sample. And finally, placing the sample into a reagent tube for sealing to finish sampling.

During the sampling process, the patient inevitably feels discomfort due to the hardness of the reagent stick (pharyngeal swab). Patients sometimes suffer symptoms such as nausea and cough, and in addition, the hard reagent bar can damage the cavity wall, thereby causing additional pain to the patients.
