Self-service type pharyngoscope nucleic acid sampling device
Technical Field
The utility model belongs to the technical field of medical equipment, especially, relate to a self-service pharynx test seed nucleic acid sampling device.
Background
With the spread of new coronary pneumonia, more and more people are infected by viruses all over the world, nucleic acid detection is the only standard for determining whether to infect new coronas, and the national nucleic acid detection is imperative based on the increasing number of asymptomatic infectors at present.
Throat swab nucleic acid detection is the main detection way for determining novel coronavirus infection at present. This operation requires a nurse to use a long test bar to collect a sample from the posterior pharyngeal wall of a patient, and during the sampling process, the sampled person (defined as the person to be sampled) is stimulated to easily cough and sneeze to form aerosol, and the aerosol is one of the important transmission paths of the novel coronavirus infection; in addition, some samplers cause vomiting due to throat irritation, and recent studies have shown that (new coronavirus detected in stool), vomit may also be a potential source of infection.
Therefore, people go to hospitals to receive professional medical sampling, go to hospitals to carry out throat swab nucleic acid detection by nurses, not only cause personnel gathering to cause the risk of illness state diffusion, but also increase the risk of infection of workers, meanwhile, because the personnel who sample are numerous, a large amount of medical personnel need to be invested, and the economic pressure of the personnel and the country of the academies is increased.
In order to prevent the infection of medical staff, the protection measures adopted by the medical staff at present are protection devices such as a wearing mask, a protective clothing, a protective goggles or an eye-protection mask, or protection devices disclosed by an authorized bulletin number CN210472180U named as 'a protection device for collecting pharynx test', wherein a transparent barrier is erected between a sampling worker and the sampling worker, and the sampling worker samples the sampling worker by penetrating two corrugated pipes arranged on the transparent barrier through two hands without influencing the sight line and the operation.
The device or the similar device can ensure the safety of sampling workers to a certain extent, reduces cross infection among doctors and patients, but still cannot achieve complete doctor-patient isolation, and still needs a lot of manpower and material resources to carry out first-line high-risk work, thereby increasing the economic pressure of workers and countries for academists and simultaneously increasing huge mental pressure for vast medical workers.
