Inhalation Device

A mouthpiece capable of being used with an inhalation device to introduce a medicament to the oral cavity of a person using the inhalation device through the mouthpiece, the mouthpiece having a first end provided with a bite element for engaging with the teeth of a person using the mouthpiece to assist in securely maintaining the first end of the mouthpiece within the mouth during use and a lip sealing element for cooperatively engaging with the lips of a person to substantially seal the first end of the mouthpiece to the mouth and a second end connected to or connectable to the inhalation device wherein the first end is in fluid communication with a second end so that when the teeth are used to hold the bite element and lips engage with the lip sealing element to seal the first end of the mouthpiece to the mouth, medicament within the inhalation device can be withdrawn through the mouthpiece into the mouth of the person into the mouthpiece so that substantially all of the dosage of medicament is delivered to the person.

A dosage device capable of assisting in delivering a measured dose of a medicament to a person using the dosage device, said dosage device comprising a storage chamber for at least temporarily storing a measured dose of a medicament after introduction of a medicament into the chamber, the storage chamber provided with an inlet for admitting the measured dose of a medicament to the storage chamber and a mouthpiece portion adapted for cooperation with the mouth of a person to withdraw the measured dosage of medicament into the mouth of a person upon inhalation by the person wherein the mouthpiece is provided with a bite element for engaging with the teeth of the person using the dosage device to assist in delivering substantially all of the dosage to the person.

A mouth piece for use in connection with an inhalation device comprising at least a delivery tube capable of connection to a source of medicament forming the main body of the mouthpiece, a bite element located at or towards one end of the delivery tube adapted for engagement with the teeth of a person using the mouthpiece and a lip sealing element or profile located around the tube for sealingly engaging with the lips and/or mouth of a person to substantially seal the mouthpiece to the lips and/or mouth wherein the bite element assists in locating the end of the mouthpiece securely within the mouth and the lip sealing element substantially seals the mouth to assist in allowing substantially all of the measured dose of the medicament to be delivered to the airways of a person through the mouth.

A delivery system for introducing a medicament into the oral cavity of a person requiring treatment for a bronchial and/or lung condition comprising a storage space for receiving and holding a dose of the medicament prior to introducing the medicament to the airways of a person through the person inhaling, wherein a storage space is provided with at least one vent for directing and/or exhausting air exhaled from the person using the device away from the storage space for discharge from the device away from the storage space so as to vent the exhaled breath to atmosphere thereby reducing or eliminating the chance of contaminating or cross-contaminating the storage space or the contents of the storage space through admitting the exhaled breath to the storage space.
