Abstract: The present invention provides a new inhaler device for the storage and/or administration of inhalable liquids to a patient offering one or more advantages or improvements over known inhalers, particularly inhalers for the delivery of halogenated volatile liquids such as methoxyflurane for use as an analgesic.

Abstract: An inhaler device includes a sealed elongated body having air inlet and mouthpiece ends, a first end-seal sealing the air inlet end, a second end-seal sealing the mouthpiece end, and passive evaporation support material pre-loaded with methoxyflurane liquid. As the methoxyflurane liquid forms a vapor, the elongated body forms a vapor chamber such that the stored vapor is available for direct administration upon opening the first and second end-seals. The first end-seal is a resealable, adjustable end cap with an air inlet groove or hole that forms an air inlet opening when opened such that the air inlet's size is adjustable. The second end-seal is a resealable, adjustable end cap including a mouthpiece chamber configured such that when closed the vapor chamber is sealed from the mouthpiece chamber and when open vapor flows radially inward into the mouthpiece chamber through vents located in a side wall of the mouthpiece chamber.

Abstract: An inhaler device for the delivery of an inhalable liquid to a patient includes an inhaler body, at least one air inlet opening, at least one vapor inhalation opening, and a storage sachet located within the inhaler body. The storage sachet includes a vapor impermeable film or foil for sealingly storing a passive evaporation support material pre-loaded with the inhalable liquid. The stored liquid is configured to be released from the storage sachet into the inhaler body in the form of a vapor when the sachet is opened and further wherein the air inlet opening and vapor inhalation opening provide an air/vapor pathway through the inhaler body. The storage sachet includes a pull tab that protrudes through an opening in the inhaler body and configured such that the pull tab can be gripped and pulled by the user to open the storage sachet.
