Abstract
A filter device and method of filtering components from a surgery plume. The filter device is comprised of a plurality of elements which react with one or more components of a surgery plume, such as that generated during electrocautery or laser surgery. The filter device, particularly in conjunction with a separate particle filter, removes cyanide, formaldehyde, benzene, and particulates, as well as odor-causing species and moisture from the surgery plume.
Claims18
A filter assembly for receiving and treating an airstream containing a gaseous and particulate materials from a surgery plume, comprising:
- a canister having an inlet and an outlet, said inlet adapted to receive an airstream containing gaseous and particulate materials from a surgery plume;
- introducing means for introducing an aqueous solution comprises of oxidizing and surface active components downstream of said canister inlet;
- a first porous member means in said canister for receiving said aqueous solution and said gaseous and particulate materials and for generating a foam by interaction of said aqueous solution and said airstream through said porous member, the first porous member means being located downstream of said introducing means;
- and
- activated carbon in said canister downstream of said inlet through which said airstream flows.
The filter assembly of claim having means to draw gaseous and particulate materials generated during electrocautery into said canister.
A filter assembly for receiving and treating an airstream containing gaseous and particulate materials including cyanide, aldehyde and benzene from a surgery plume, comprising:
- a canister having an inlet and an outlet, said inlet adapted to receive an airstream containing gaseous and particulate materials from a surgery plume;
- a filter member inside said canister incorporating a component reactive to cyanide downstream of said inlet;
- a discrete desiccant layer inside said canister downstream of said filter component reactive to cyanide;
- a filter member inside said canister incorporating a component reactive to aldehydes downstream of said inlet;
- and
- a discrete layer of activated carbon downstream of said desiccant layer for removing said benzene.
A system for receiving and treating an airstream containing gaseous and particulate materials from a surgery plume, comprising:
- a canister having a flow path defined between an inlet and an outlet of the canister wherein an airstream is received through the inlet, treated within the canister and exhausted from the outlet, said inlet for receiving said airstream containing gaseous and particulate materials from said surgery plume;
- said canister having a means for introducing an aqueous solution comprised of oxidizing and surface active components for treating the airstream;
- a first filter component in said canister downstream of said inlet which is positioned to receive said aqueous solution and said airstream containing said gaseous and particulate materials, the first filter component having porous means for generating a foam through interaction of said aqueous solution and said airstream in said porous means;
- and
- an activated carbon filter component in said canister positioned downstream of said inlet in a flow path through which the airstream flows.
