Detection reagent rod with buffer solution

Abstract

A detection reagent rod with a buffer solution comprises a rod body and a rod sleeve, a sampling brush used for draining collected liquid is arranged at the front end of the rod body and comprises a flexible brush head and a brush handle, one end of the brush handle is fixedly connected with the front end of the rod body, the other end of the brush handle is connected with the flexible brush head, two ends of the rod sleeve are respectively provided with two cavities, one cavity is used as a protective sleeve at the head end of the rod body, the other cavity is a buffer solution tube, and the buffer solution is contained in the buffer solution tube. Compared with the prior art, the detection reagent rod with the buffer solution has the advantages that the sampling brush, the brush head and the brush handle adopted by the reagent rod are made of an integrated material, the brush head is relatively soft after being roughened, has relatively small stimulation to the oral cavity, the pharynx and even the nasal cavity, and can be used for sampling detection of the anterior nose and the pharynx, the detection can be completed by only one step, the test steps are saved, and the test efficiency is improved; and the application range that only saliva can be collected as a sample in the prior art is expanded.

Description

technical field [0001] The invention relates to the technical field of medical consumables, in particular to a detection reagent stick with a buffer. Background technique [0002] The confirmation of respiratory infectious diseases requires nucleic acid testing. Nucleic acid testing is roughly divided into two steps: 1) collecting patient samples; 2) testing at the testing center. The first step of sample collection has relatively high requirements on the location of the collection, and it must reach the posterior pharyngeal wall or tonsil, otherwise the accuracy of the test will be affected. Doctors generally prepare a reagent stick (pharyngeal swab) similar to a long cotton swab and a reagent tube. The patient should take off the mask, then open his mouth and make an "ah" sound, so as to expose the posterior pharyngeal wall. At this time, the doctor extended the reagent stick to the back wall of the patient's pharynx, rubbed it and took a sample. Finally, put the sample...

Problems solved by technology

Patients sometimes have symptoms such as nausea and coughing. In addition, the hard reagent stick will damage the wall of the cavity, adding additional pain to the patient.
