主权项

1. A collapsible inhalation device for use with a metered dose inhaler (MDI) dispenser, the MDI dispenser operable to dispense a dose of a medication therefrom, the inhalation device comprising:
an outlet end member including a mouthpiece; an inlet end member including an inlet port and an MDI dispenser mount structure configured to receive and engage the MDI dispenser; and a tubular, pliable, collapsible sleeve member having first and second opposed ends attached to the inlet end member and the outlet end member, respectively; wherein the inhalation device is positionable in each of an open position, wherein the outlet end member and the inlet end member are spaced apart and the sleeve member is extended such that the outlet end member, the inlet end member and the sleeve member define a chamber, and a closed position, wherein the sleeve member is collapsed and the outlet end member and the inlet end member are proximate one another and envelope the sleeve member; andwherein, when the inhalation device is in the open position with the MDI dispenser mounted in the MDI dispenser mount structure, a dose of the medication can be dispensed from the MDI dispenser into the chamber through the inlet port to mix with air in the chamber and thereby form a mixture of the air and the dose of the medication that can be inhaled by a patient from the chamber through the mouthpiece.
