While most country is taking active measures to address the epidemic as it intensifies, we are noticed that there are frequent instances of failed nucleic acid tests or inadequate collection of samples in the increasingly strained supply of medical facilities. Therefore, we adopt the idea of " inflating the swab ". After placing a small swab into a narrow mouth or nose space, the sample collection area can be enlarged with simple manipulation, it could better help doctors or medical volunteers collect samples deep in the subject's mouth or nose. In addition, it can also reduce the discomfort of the subjects.
