Method of installing an anti-siphon flow restricter for a nebulizer

摘要

A method of installing an anti-siphon flow restricter into a gas flow lumen of a nebulizer includes providing an anti-siphon flow restricter having a side wall conforming to a cross section of the gas flow lumen, first and second ends at opposite ends of the side wall and an elastomeric diaphragm closing the first end of the side wall. The anti-siphon flow restricter is axially inserted into the gas flow lumen with the diaphragm leading. The diaphragm is slit and allowed to self-bias closed.
