Biological hazard protection store and collective bag

Abstract

An innovated structure of biological protection collecting bag, having a medical grade filter screen installed inside the collecting bag, allowing free air flow into and out of the bag, thereby completely filtering and arresting pathogens inside the bag. Meanwhile, the bag opening is sealed by a plurality of airtight sealing strips, so the user can quickly and hermetically seal the bag without having to squeeze on the collecting bag, thereby effectively preventing pathogens from contaminating the ambient environment during handling and stacking processes.
