Embodiment approach

[0057] Embodiments will now be described with reference to non-limiting examples.

[0058] The device of the present invention includes a passively vaporized support material preloaded with an inhalable liquid to provide a portable, ready-to-use integrated drug storage and delivery device. Compared to prior art inhaler devices for methoxyflurane, the device of the present invention provides improved pain relief when rapid pain relief is required e.g. in emergency, non-hospital, remote, outdoor settings, sports, humanitarian aid Devices that are easy to apply, especially self-administered, and / or in a field operating environment.

[0059] According to a first aspect, there is provided an inhaler device for delivering an inhalable liquid to a patient, the device comprising:

[0060] (1) Inhaler body;

[0061] (2) At least one air inlet opening;

[0062] (3) At least one vapor intake opening; and

[0063] (4) a storage sachet comprising a vapor-impermeable film or foil for he...

example 1

[0164] figure 1 Green Whistle showing prior art TMInhaler device 1 (Medical Developments International Limited), which is currently used in Australia to deliver (methoxyflurane) (1.5 mL or 3 mL amber glass vial container with screw cap for storage). When required for use, the delivered dose of methoxyflurane is poured into the base end 3 of the device. After the dose is poured into the base end for delivery onto a vaporization device (not shown), the methoxyflurane vaporizes so that the patient can self-administer the analgesic by inhaling the air / vapor mixture through the mouthpiece 2 . If the patient continues to breathe through the mouthpiece, any exhaled air / vapor mixture will exit the device via an externally fitted chamber comprising activated carbon "AC chamber" 4 .

example 2

[0166] Figure 2 shows an inhaler device 5 according to an embodiment of the invention. Figure 2A An external view of the device is shown in , where the cross-sectional shape of the inhaler body, apart from the tapered nozzle 6 , is shown as a rounded rectangular shape 7 . The pull-tab 8 of the storage sachet inside the inhaler protrudes from the opening to allow the user to grasp and move along the Figure 2B Pull in the direction of the arrow shown in to open the storage sachet. The cross-sectional view shown in Figure 2C shows the inhaler device in use. The storage sachet is positioned within the air intake chamber 9 . The air inlet chamber comprises an air inlet opening 9a from which the tab protrudes and which enables air to flow through the air inlet chamber and across the edge of the passive evaporative support material 10 once the storage sachet is opened. The surface is exposed and air is enabled to flow into the nozzle chamber to deliver the released vapor to the ...

Abstract

An inhaler device for delivering an inhalable liquid to a patient, the device comprising: (1) an inhaler body; (2) at least one air inlet opening; (3) at least one vapor inhalation opening; and (4) A storage sachet comprising a vapor-impermeable membrane or foil for hermetically storing a passive vaporization support material preloaded with an inhalable liquid; wherein, when the sachet is opened, the inhalable liquid is released from the storage The sachet is released into the inhaler body for administration to the patient, and further wherein the air inlet opening and the vapor inhalation opening provide an air / vapor pathway.

Description

technical field [0001] The present invention relates to inhaler devices for inhalable liquids, in particular for storing and / or administering inhalable volatile liquids, such as halogenated volatile liquids, to a patient. Background technique [0002] Storage and administration to patients of inhalable liquids that contain or are active agents often present challenges. Due to patient preference and the convenience of self-administration as needed or in a hospital setting or other setting, active agents such as therapeutic agents or agents are often formulated for oral delivery in the form of tablets and capsules, in spray form Nasal delivery as well as liquid formulations for intravenous delivery. [0003] Where it is advantageous to administer the active agent to the lungs of a patient, for example to treat or alleviate a respiratory disease, the active agent may be administered by the oral inhalation route alone or in combination with the nasal route. Suitable inhaler de...
