The utility model discloses a 135 degrees contained angles between first probe rod and second probe rod, the cooperation holding rod can be so that the through nasopharynx portion of sampling head, has solved the various problems of intranasal route, has avoided leading to detecting out the condition of false negative because the dissection characteristic of nasal cavity, has improved the rate of accuracy of sample collection, adopts the sampling head that has sawtooth appearance face simultaneously, has increased the area of contact of sampling, and the full coverage is scratched and is scraped nasopharynx portion.
Description
Technical Field
The utility model relates to a detection device specifically is a new-type pneumonia sample collection system that is suitable for.
Background
At present, when a human body is detected for a new crown disease, a nasopharynx sampling swab is mostly adopted for sampling, but due to the characteristics of the anatomical structure of the nasal cavity of the human body, the nasal septum is rarely completely centered, most people have deflected nasal septum, the nasal cavity has a plurality of narrow parts, the nasopharynx is not easy to reach in the sampling process, and the nasopharynx sampling swab is easy to cause sneezing, nasal cavity pain and even bleeding, and a patient is not matched, so that false negative is caused; secondly, when the patient has upper respiratory symptoms, the nasal turbinates are congested, edematous and narrower, and the nasal turbinates are not easy to reach the nasopharynx part in the sampling process, so that false negative is caused; if the third nasal cavity has nasal space occupying lesion, such as nasal polyp, nasal cavity tumor and the like, the third nasal cavity is more difficult to reach the nasopharynx part, so that false negative is caused; the fourth nasopharynx swab is withdrawn from the narrow nasal cavity, so that the number of samples to be sampled is reduced easily. Therefore, we improve the method and provide a novel coronary pneumonia specimen collecting device.
SUMMERY OF THE UTILITY MODEL
