咽拭子是一种从咽喉处收集口腔分泌物的临床测试样本的方法,人类在抗击各类病毒时会经常用到,相较于鼻拭子采样,咽拭子采样是相对简单且用户广泛接受的检测方法。目前,确诊新冠肺炎最主要的检测手段是核酸检测,通过直接对采集标本中的病毒核酸进行检测,来确定被测者是否感染病毒。Pharyngeal swab is a method of collecting clinical test samples of oral secretions from the throat. Humans often use it when fighting various viruses. Compared with nasal swab sampling, throat swab sampling is relatively simple and widely used Accepted test methods. At present, the most important detection method for the diagnosis of new coronary pneumonia is nucleic acid detection, which directly detects the viral nucleic acid in the collected specimens to determine whether the tested person is infected with the virus.
然而,作为一种常用的传染病医学检测方式,咽拭子采样过程,常见的还是靠一对一的人工手动采集。人员密集、工作量大,咽喉部生物样本的采集具有高危感染性,医护人员要穿隔离服自我保护,造成身心痛苦。关键是不能避免医护人员的感染和被测者之间的交叉感染,有可能致使疫情进一步发展。However, as a commonly used medical detection method for infectious diseases, the throat swab sampling process is usually collected manually one-to-one. The staff is dense and the workload is heavy, and the collection of biological samples from the throat is highly infectious. Medical staff have to wear isolation suits to protect themselves, causing physical and mental pain. The key is that the infection of medical staff and the cross-infection between the tested persons cannot be avoided, which may lead to the further development of the epidemic.
因此,需要一种咽拭子自动采样设备来代替医护人员对病患进行采样。该设备无需医护人员操作,被测者只要按照说明步骤自助操作即可。Therefore, need a kind of pharyngeal swab automatic sampling equipment to replace medical personnel to take samples to patients. The device does not need to be operated by medical staff, and the subjects only need to follow the instructions to operate it by themselves.
