摘要：
1. A device for delivering a composition to the olfactory region of the nasal cavity, comprising: a container capable of holding a propellant, a diffuser communicating with the container, a chamber for the composition communicating with a diffuser, while the chamber for the composition is capable of containing the composition, and nozzle communicating with the chamber for the composition moreover, the device is capable of delivering the composition to the olfactory region of the nasal cavity. 2. The device according to claim 1, in which the container is under pressure. The device according to claim 1, wherein the propellant is at least one of hydrofluoroalkane, nitrogen, or chlorofluorocarbon. The device according to claim 1, wherein the composition is capable of being contained in the chamber for the composition, is a medicine or diagnostic tool. The device according to claim 4, in which the drug is an oxime. The device according to claim 1, wherein the diffuser is a frit. The device according to claim 4, wherein the diagnostic agent is a radiopharmaceutical. The device according to claim 1, in which the propellant is a liquid under pressure. The device of claim 8, wherein the liquid under pressure is a hydrofluoroalkane. The device according to claim 9, in which, when the device is actuated, the liquid hydrofluoroalkane, which is under pressure, is released from the container and interacts with the diffuser, while the liquid hydrofluoroalkane, which is under pressure, is converted into gaseous hydrofluoroalkane. The device of claim 10, wherein a smaller portion of the pressurized hydrofluoroalkane is converted to gaseous hydrofluoroalkane. The device according to claim 10, in which most of the liquid hydrofluoroalkane located under1.
