  • Publication number: 20100083963
    Abstract: A portable medication holder is disclosed for discharging liquid agent into an air stream. The holder comprises a housing having a first wall and a second wall with the walls movable relative to each other. The second wall may be moved between a closed position and an open position wherein an air pathway is open. The holder has evaporation means to assist in evaporation of the liquid agent into air in the air pathway which flows through a medication discharge chute to a user. The device also includes opening means for opening the medication container and releasing the liquid agent to the air pathway and one or more one-way valves to provide uni-directional air flow for one or both of the inspiratory air and expired air. The liquid agent is preferably methoxyflurane. The device may include an auxiliary gas pathway for delivery of a gas such as oxygen. It may also include an auxiliary air inlet for varying the concentration of inhaled agent. The holder is preferably sealed against the external environment.

  • Patent number: 7686016
    Abstract: A medication holder is disclosed comprising a housing (10) having an outer wall (12) and an inner wall (11) preferably in sleeved relationship to each other. The outer wall may be moved between a closed position in which the housing (10) is sealed for ingress of moisture or other contaminants and an open position providing access to the medication container discharge outlet. The second wall may (12) be slid longitudinally or rotated circumferentially to access the cavity and may, in the process, open an air pathway through the cavity. The medication container is preferably a pressurized canister (22). Alternatively, it may comprise a frangible vial (603) with a volatile liquid. In the latter case, an evaporation grid (563) may also be supplied to enhance absorption of the liquid which is preferably methoxyfluorane. Opening means (561) may be provided to open the frangible vial and discharge the contents onto the evaporation means (563) which is in fluid contact with the air pathway (806).

  • Patent number: 7677244
    Abstract: Breathing apparatus for medicating an airstream, compring a breathing apparatus (139), a medication chamber (138) adapted to store and discharge a therapeutic agent, a delivery pathway (141) between the chamber (138) and an intake air pathway and releasing means (145) for selectively discharging the therapeutic agent from the chamber (138) into the intake air pathway. The apparatus is particularly suited for scuba diving, snorkels, gas masks and filters. The invention is suitable for asthma sufferers but also extends to other respiratory diseases. Also claimed are a medication chamber for use in medicating an airstream and a method of medicating an airstream.

  • Publication number: 20080251551
    Abstract: The specification describes a medication dispenser for receiving a pressurised medication container and discharging therapeutic doses therefrom. The medication dispenser comprises an elongate tubular body with a cavity formed in the body and adapted to receive a medication container. Lateral aperture is formed in the body and communicates with the cavity. A sleeve is rotatably mounted to a first end region of the medication dispenser. The sleeve has a sleeve aperture which moves into and out of alignment with the lateral aperture during rotation of the sleeve. A mouthpiece moves between a discharge position and a storage position with rotation of the sleeve. The tubular body has a longitudinal axis which deviates away from the position of the extended mouthpiece, the deviation occurring outside the first end region. The invention may extend to a carrier for use with the medication dispenser.
