    Abstract: An air plenum provides protection from viruses and particulates to a user located beneath the air plenum. The air plenum has a housing with a fan centrally located within the housing. Low-velocity air is emitted downwardly from the fan through a perforated screen on a lower side of the housing onto the user. A slot diffuser extends around a lower periphery of the housing and emits high-velocity air downwardly to form an air curtain around the user. The higher velocity air of the air curtain reduces the ability of unwanted particulate matter to enter the area that is below the perforated screen.

  • Patent number: 10954573
    Abstract: Embodiments of the present disclosure are directed to systems and methods for collection and analysis of environmental air dust (EAD) within an individually ventilated cage rack (IVR) environment for detecting pathogens. The method includes collection of an EAD sample by a collection media, isolation of a plurality of nucleic acids (e.g., RNA and/or DNA) representative of one or more infectious agents from the EAD sample, optional reverse transcription of RNA to cDNA if the isolated nucleic acids contain RNA, amplification of the cDNA and/or DNA (e.g., by polymerase chain reaction (PCR)), and assay interpretation. Optionally, the EAD sample may be analyzed with one or more other sample types (e.g., fecal pellets, oral swabs, body swabs, tissue, etc.) to improve detection of low-copy organisms.
