  • Patent number: 9028437
    Abstract: A method and apparatus for treating gas for delivery into a body cavity, body space or body surface of an animal. The apparatus comprises a housing defining a chamber having an entry port and an exit port. One or more agents are released into the gas stream that flows through the chamber so that the gas stream carries the agent to the animal. Also shown, for use with, or without, the chamber, is an agent chamber adapted to be coupled to at least one structure defining at least one fluid flow path extending at least a portion of the distance between an insufflation device and the body cavity, body space or body surface.
    Type: Grant

  • Patent number: 4836931
    Abstract: There is disclosed a porous, vacuum formed filter tube having randomly oriented glass fibers and having at least one layer of a suitable sheet material wrapped around said porous filter tube and being in intimate contact therewith, said disclosed combination having an outer support structure of a predetermined inside diameter sufficient to compress the assembly of said porous filter tube and said material when it is slipped thereover, thus providing compression from the outside to the inside and forcing the layer of sheet material into intimate contact at virtually all points with said porous filter tube.
