Description

Technical Field

[0001] The utility model relates to the technical field of virus detection, in particular to a sampling auxiliary device that is convenient for virus detection. Background Art

[0002] Viruses are tiny, simple, non-cellular organisms containing only one type of nucleic acid. They must parasitize and replicate within living cells. As a non-cellular life form, viruses consist of a long chain of nucleic acid and a protein shell. They lack their own metabolic machinery and enzyme systems. Therefore, once outside the host cell, viruses become chemical substances without any life activities and cannot independently reproduce. Their replication, transcription, and translation are all carried out within the host cell. Once inside the host cell, they can utilize the cellular substances and energy to carry out their life activities, producing new generations of viruses identical to themselves according to the genetic information contained in their nucleic acid. Virus testing involves detecting viruses or viral antigens in infected tissue cells to diagnose viral infections. Virus testing requires the use of a rubber-tipped pipette, but after sampling, the rubber-tipped pipette may accidentally touch the rubber tip or leak naturally. Utility Model Content
