The invention provides for an improved method of containing air-born
contaminants emanating
from an infected patient. The infection Control Vent Hood is a mechanical
device that is placed
in close proximity to an infected patient with the intended purpose of
collecting the "sneezing - coughing"
and other contaminated air-streams complete with diseased body fluid particles
emitted from a patient. Typically; the application would involve placing the
air collection device
(vent hood) over, that is: in close proximity to, the infected person, who
would be lying prone,
perhaps incapacitated, in a hospital bed. The infection control vent hood
captures these
emanations and directs them to sterilization equipment or to discharge in a
safe zone.
Technical Development and claimed Improvement in the Art of Infection Control:
Typically, hospital rooms containing infected patients use a centralized HVAC
air control
system. Air is conditioned by heating, cooling, humidifying and filtering by
commercial air-conditioning
equipment and then directed to the patient area. To allow for air in-
migration,
allowance must also be made for air extraction. This leaving air may be
directed to "HVAC
return-air-systems" for filtering and re-use. Typical practice is to salvage
the heated air, filter it,
and then re-use this air along with 10 to 20% of outside fresh air and send
that mixture back to
the hospital room where the process is repeated.
Investigation has shown that a single sneeze has the potential to infect an
entire room with
viruses, bacteria and other biological material. Research has also shown that
the heavier water
droplets from a sneeze may fall to the floor where they evaporate. Infected
material contained
within those droplets can later be disturbed by people walking by and re-
introduce these
particles into air flows within the room where it is captured by the HVAC
systems and re-circulated.
The purpose of this mechanical device is to protect medical personnel such as
doctors and nurses and also other non-infected persons in close proximity to
the infected
patient by removing, as much as possible, those contaminated emissions.
The Infection Control Vent Hood is not intended to replace the HVAC system in
a room, rather
its purpose is to capture sneezes and other air born emissions from the
patient and vent only
those air-streams to safe disposal.
