  • 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.

  • Patent number: 9017280
    Abstract: An apparatus for conditioning gas for use in a medical procedure, the gas being received into the apparatus from a gas source. The apparatus comprises a housing defining a chamber having an entry port and an exit port. The housing contains at least a humidification means comprising a container for liquid, such as at least one liquid retaining layer that is disposed within the chamber in the path of travel of the gas for humidifying the gas as it passes through the chamber. A humidity sensor may be disposed within the chamber that senses the humidity of the gas exiting the chamber. A monitoring circuit is connected to the humidity sensor that detects when the chamber requires a recharge of liquid based on the humidity of the gas in the chamber, and generates a recharge signal indicative thereof a charging port on the housing provides access into the chamber to recharge the chamber with water. Alternatively, a backup container of liquid is provided to continuously supply liquid to the humidification means.

  • Patent number: 8715264
    Abstract: A charged hydration device and a method of filling the hydration device so the charged hydration that can be mounted to a medical apparatus that provides insufflation fluid to a body cavity either immediately prior to the medical procedure or during a medical procedure with the charged hydration device including an inlet and outlet for an inline connection with the medical apparatus so that an insufflation gas delivered through the charged hydration device is hydrated to prevent tissue damage to a person receiving the insufflation gas.
