Inhalation apparatus
View Patent ↗An inhaler is instantly activated upon its removal from a cover or cover unit, and by rotating a cartridge component of the inhaler with respect to a mouthpiece portion, so as to create a flow pathway for ambient air and particles. The cartridge component includes a chamber, whose contents typically include dry powders or the like. Upon creation of the flow pathway, the contents of the chamber are instantly accessible for immediate inhalation by a user through the mouthpiece portion.
1. An inhalation apparatus comprising:
a mouthpiece including a central bore having at least one open end and tube for carrying particles to the oral cavity of a user;
a single use cartridge including at least one portion for receipt in the bore and a chamber for storing a single dose of an inhalable substance;
the mouthpiece and the cartridge being in rotatable engagement with respect to each other, from a first position where the chamber is closed to the ambient environment and the tube, to a second position, where a flow pathway is formed from the ambient environment and the tube of the mouthpiece through the chamber in an open configuration; and
the mouthpiece including detents having edges not allowing a movement back to the first position.
2. The apparatus of claim 1 , additionally comprising a cover, the cover adapted for covering the mouthpiece.
3. The apparatus of claim 2 , wherein the cover and the cartridge include cooperatingly configured structures for retaining the cover in an engagement with the cartridge, once the cover has been placed on the cartridge.
4. The apparatus of claim 1 , wherein the cartridge comprises a collimation tube.
5. The apparatus of claim 4 , wherein the chamber further comprises at least one protrusion.
6. The apparatus of claim 5 , wherein the chamber further comprises two or more grooves.
7. The apparatus of claim 6 , wherein the at least one protrusion and the two or more grooves together with a collimation tube are configured to create vortices when the apparatus is in use in the second position.
8. The apparatus of claim 5 , wherein the apparatus comprises a collimation tube configured to direct an airflow at the at least one protrusion in said chamber in use.
9. The apparatus of claim 1 , further comprising an inhalant in the chamber.
10. The apparatus of claim 9 , wherein the inhalant is the form of a dry powder.
11. An inhalation method, comprising:
providing an inhalable substance in a chamber of an inhalation apparatus comprising:
a mouthpiece including a central bore having at least one open end and a tube for carrying particles to the oral cavity of a user;
a single use cartridge including at least one portion for receipt in the bore and a chamber for storing a single dose of an inhalable substance;
the mouthpiece and the cartridge being rotatable engagement with respect to each other, from a first position, where the chamber is closed to the ambient environment and the tube, to a second position, where a flow pathway from the ambient environment to the tube of the mouthpiece through the chamber, has been opened;
the mouthpiece including detents having edges not allowing a movement back to the first position; and
rotating the cartridge with respect to the mouthpiece to from the first position to the second position to open the flow pathway and locking the cartridge with respect to the mouthpiece in the second position.
