PATHOGEN SAMPLING PROTOCOLS AND SYSTEMS

摘要

A system is disclosed for sampling contaminants from a soft test surface that includes a vacuum sampling device. The vacuum sampling device includes a spray port that is in fluid communication with source of sterilized sampling fluid, and which delivers a quantity of sampling fluid onto the soft test surface, a suction head having an outer casing surrounding an open-faced suction cavity that is in communication with a vacuum source and which retrieves the sampling fluid from the test surface, and a storage container for holding the retrieved sampling fluid. The system further includes a retention screen positioned between the test surface and the suction head, and which prevents the soft test surface from substantially occluding suction and reducing mobility of the suction head when engaging the soft test surface.
