Nasal delivery device
First Claim
1. A two-step mechanism for delivering a flowable substance to the nasal passages of a patient, said two-step mechanism comprising:
- a. a nosepiece configured to be in fluid connection with said nasal passages;
b. an openable at least one air-tight enclosure, configured to contain a predetermined amount of gas;
said predetermined amount of gas compressible to a predetermined amount of pressure;
c. a charging mechanism, fluidly connected with said at least one air-tight enclosure, characterized by at least two configurations;
a retracted configuration and an extended configuration;
where, when said charging mechanism is transformed from said extended configuration to said retracted configuration, said charging mechanism is configured to enable delivery of said predetermined amount of gas from at least one first predetermined position in said at least one air-tight enclosure to at least one second predetermined position, said charging mechanism comprising a member of a group consisting of a piston drivable by a lever, an openable air-tight compartment preloaded with said predetermined amount of gas compressed to said predetermined amount of pressure, and any combination thereof; and
d. an activation mechanism, configured, upon activation, to release said predetermined amount of gas compressed to said predetermined amount of pressure from said at least one second predetermined position so as to entrain said flowable substance within said predetermined amount of gas and to deliver the same from said at least one second predetermined position to said nasal passages, said activation mechanism comprising a gas release mechanism selected from a group consisting of a valve mechanism, an air flow regulator, a rod configured to pierce the air-tight compartment, a spear configured to pierce the air-tight compartment, a needle configured to pierce the air-tight compartment, a knife configured to pierce the air-tight compartment, and any combination thereof;
wherein said two-step mechanism additionally comprises a mouthpiece connected to said charging mechanism;
said mouthpiece connected to said activation mechanism;
said activation being by application of suction to said activation mechanism through said mouthpiece.

Abstract
The present invention provides a two-step mechanism for delivering a flowable substance to the nasal passages, comprising: a. a nosepiece adapted to be in fluid connection with said nasal passages; b. at least one air-tight enclosure, comprising predetermined amount of compressed gas in the same; said compressed gas is pressurized to predetermined amount of pressure; c. a charging mechanism, fluidly connected with said air-tight enclosure, characterized by at least two configurations: a retracted position and an extended position; where, when said charging mechanism is transformed from said extended position to said retracted position, said charging mechanism is adapted to enable delivery of said pressurized and predetermined amount of compressed gas from at least one first predetermined position in said air-tight enclosure to at least one second predetermined position; d. an activation mechanism, adapted to entrain said flowable substance within said pressurized and predetermined amount of compressed gas.

12. A method for delivering a flowable substance to the nasal passages of a patient, comprising steps of:
-
i. providing a two-step mechanism for delivering said flowable substance to the nasal passages, said two-step mechanism comprising; 1. a nosepiece configured to be in fluid connection with said nasal passages; 2. an openable at least one air-tight enclosure, configured to contain a predetermined amount of gas;
said predetermined amount of gas compressible to a predetermined amount of pressure;3. a charging mechanism fluidly connected with said at least one air-tight enclosure, characterized by at least two configurations;
a retracted configuration and an extended configuration;
where, when said charging mechanism is transformed from said extended configuration to said retracted configuration, said charging mechanism is configured to deliver said predetermined amount of gas from at least one first predetermined position in said at least one air-tight enclosure to at least one second predetermined position;
said charging mechanism comprising a member of a group consisting of a piston drivable by a lever, an openable air-tight compartment containing said predetermined amount of gas compressed to said predetermined amount of pressure, any combination thereof; and
,4. an activation mechanism, configured, upon activation, to release said predetermined amount of gas compressed to said predetermined amount of pressure from said at least one second predetermined position so as to entrain said flowable substance within said predetermined amount of gas and to deliver the same from said at least one second predetermined position to said nasal passages, said activation mechanism comprising a gas release mechanism selected from a group consisting of a valve mechanism, an air flow regulator, a rod configured to pierce the air-tight compartment, a spear configured to pierce the air-tight compartment, a needle configured to pierce the air-tight compartment, a knife configured to pierce the air-tight compartment, and any combination thereof; ii. providing said flowable substance, contained within a container; iii. fluidly connecting said container with said charging mechanism and said nosepiece; iv. charging said two-step mechanism by transforming said charging mechanism from said extended configuration to said retracted configuration;
thereby delivering said predetermined amount of gas from at least one first predetermined position in said at least one air-tight enclosure to at least one second predetermined position;v. emplacing said nosepiece in juxtaposition with a nostril in fluid connection with said nasal passages; and vi. activating said two-step mechanism;
