A dry-powder inhalation device including a casing having at least one push button located on an external portion thereof, the push button including at least one pin structure, an air inlet located at a first terminus of the casing; a powder delivery port located at a second terminus of the casing and is positioned distal to the air inlet; and an elongated support panel located within an interior of the casing and being fitted within the casing so as to partially rotate therein about a single axis. The support panel has at least one compartment containing dry-powder located proximal to the first terminus, and the at least one pin structure is located proximal to the air inlet and arranged above the dry-powder compartment. The compartment with a dry-powder includes a blister structure encasing the dry-powder, whereby airflow through the device causes the elongated support panel to partially rotate repeatedly within the casing, thereby striking the plurality of needle-like structures and releasing the dry-powder in the airflow.

1. An inhaler device comprising: a casing having at least one push button mechanism located on an external portion thereof, the at least one push button mechanism comprising at least one pin structure that is configured to extend therefrom upon actuation thereof;an air inlet located proximal to a first terminus of the casing;a powder delivery port located proximal to a second terminus of the casing and positioned distal to the air inlet; andan elongated support panel comprising a first terminus and a second terminus at opposite ends thereof and at least one compartment containing an inhalable medicament located proximal to the first terminus of the elongated support panel and hermetically sealed by a cover that is configured to be punctured by the at least one pin structure,the support panel being rotatably mounted within an interior of the casing such that the support panel partially rotates within the casing about a single axis upon flowing of air through the casing from the air inlet to the delivery port upon inhalation by a user at the second terminus of the casing;wherein, after actuation of the at least one push button mechanism to cause the at least one pin structure to project therefrom, inhalation by the user of air through the casing causes the partial rotation of the elongated support panel within the casing, causing the at least one compartment to strike the at least one pin structure, such that the at least one pin structure punctures the hermetically sealed cover and allows the medicament contained within the at least one compartment to become released into the air flowing through the device. 2. The inhaler device according to claim 1, wherein the push button mechanism is configured to extend the at least one pin structure into the interior of the casing when a force is applied and to retract the at least one pin structure from the interior of the casing when the force is released. 3. The inhaler device according to claim 1, wherein the push button mechanism comprises a housing, a top panel, and a bottom opening, the bottom opening configured to communicate with the interior of the casing. 4. The inhaler device according to claim 1, wherein at least one compartment is situated on an upper surface of the elongated support panel, and at least one push button mechanism comprising at least one pin structure is situated on an upper side of the casing. 5. The inhaler device according to claim 1, wherein at least one compartment is situated on a lower surface of the elongated support panel, and at least one push button mechanism comprising at least one pin structure is situated on a lower side of the casing. 6. The inhaler device according to claim 1, wherein the single axis of the support panel is located at a center of the support panel. 7. The inhaler device according to claim 1, wherein the single axis of the support panel is located proximal to the air inlet or proximal to the powder delivery port. 8. The inhaler device according to claim 1, wherein the compartment cover is made of aluminum or aluminum foil. 9. The inhaler device according to claim 1, wherein the casing, the elongated support panel, or a combination thereof is substantially rectangular. 10. The inhaler device according to claim 1, wherein the support panel comprises at least two compartments containing an inhalable medicament. 11. The inhaler device according to claim 10, wherein the two or more compartments each houses a different inhalable medicament. 12. The inhaler device according to claim 1, wherein the compartment containing the inhalable medicament comprises at least one partition, creating at least two separate chambers in the compartment. 13. The inhaler device according to claim 12, wherein each of the at least two separate chambers houses a different inhalable medicament. 14. The inhaler device according to claim 1, wherein the inhalable medicament is a therapeutic agent in the form of a dry-powder. 15. The inhaler device according to claim 14, wherein the therapeutic agent is a drug or a vaccine. 16. An inhaler device comprising: a casing having an air inlet, a powder delivery port located opposite the air inlet, and at least one push button mechanism comprising at least one pin structure that is configured to extend therefrom upon actuation thereof; andan elongated support panel located within the interior of the casing and having at least one hermetically sealed covered compartment containing a dry-powder medicament;wherein the elongated support panel is configured to partially rotate about a single axis within the casing upon air flowing through the device, the partial rotation causing the hermetically sealed covered compartment to strike the at least one pin structure once extended from the at least one push button mechanism, thereby puncturing a cover of the hermetically sealed covered compartment and releasing the dry-powder into the air flowing through the device. 17. The inhaler device according to claim 16, wherein the push button mechanism comprises a housing, a top panel, and a bottom opening, the bottom opening configured to communicate with the interior of the casing. 18. The inhaler device according to claim 16, wherein the push button mechanism is configured to extend the at least one pin structure into the interior of the casing when a force is applied thereto and retract the at least one pin structure from the interior of the casing when the force is released therefrom.
