Low flow rate nasal treatment delivery device for mixed carbon dioxide and saline

摘要

A method of treatment and a nasal delivery device for dosages containing dissolved gaseous carbon dioxide in saline fluid for treating head ailments includes: a) a main housing having a hollow central area containing the dosage; b) a dosage dispenser head located at the distal end of the main housing, having at least one flow channel for movement of the dosage from the main housing through the dosage dispenser head and externally of the dosage dispenser head; c) a dosage release control component located between the main housing and the dosage dispenser head to permit flow of the dosage through the dosage dispenser head in response to increased pressure against the dosage at a flow rate of less than 1 cc per second; and d) a pressure-changing moveable component located on the main housing.

1. A releasable nasal treatment delivery device for mixed carbon dioxide and saline for treating head ailments in a patient in need thereof, comprising:
a) a main housing having a proximal and a distal end and having a hollow central area containing a releasable nasal treatment dosage that includes a saline fluid and gaseous carbon dioxide, wherein said gaseous carbon dioxide is dissolved in said saline fluid; b) a dosage dispenser head located at said distal end of said main housing, said dosage dispenser head having at least one flow channel for movement of said dosage from said main housing through said dosage dispenser head and externally of said dosage dispenser head; c) a dosage release control component located between said main housing and said dosage dispenser head adapted to permit flow of the dosage comprising said saline fluid and said gaseous carbon dioxide from said main housing and through said dosage dispenser head in response to increased pressure against said dosage release control component wherein said permitted flow has controlled release at a flow rate of less than 1 cubic centimeter per second and wherein said flow rate is a total flow rate of said dosage; d) a pressure-changing moveable component located on said main housing; wherein, when said dosage dispenser head of said device is placed in a nasal cavity and said pressure-changing moveable component is activated by movement toward said dosage, said dosage is at least partially forced through said dosage release control component at the permitted flow rate and through said dosage dispenser head for application of said dosage to a nasal cavity wall.
