Description
Technical Field
The invention relates to a detection device, in particular to a novel collection device suitable for a new coronary pneumonia specimen.
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is more difficult to reach the nasopharynx part, so that false negative is caused; the fourth nasopharynx swab is withdrawn from the narrow nasal cavity, so that the number of samples to be sampled is reduced easily.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.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a novel coronary pneumonia specimen collecting device.
In order to solve the technical problems, the invention provides the following technical scheme:
the invention relates to a novel acquisition device suitable for a new coronary pneumonia specimen, which comprises a holding rod, wherein a sampling assembly is arranged on the holding rod, the sampling assembly consists of a first probe rod, a second probe rod and a sampling head, one end of the first probe rod is fixedly connected with one end of the holding rod, one end of the second probe rod is fixedly connected with the other end of the first probe rod, an included angle between the second probe rod and the first probe rod is 135 degrees, the bottom end of the sampling head is fixedly connected with the other end of the second probe rod, one side surface of the sampling head, which is far away from the holding rod, is a sawtooth-like surface, and the cross section of the sampling head is elliptical.
