摘要：
Described is an atomizing nozzle having a relatively small frontal area permitting insertion of a nozzle into small diameter medical conduit(s). A body of a preferred nozzle has a characteristic size (e.g., cross-section diameter) of less than about 0.2 inch (0.5 cm). The nozzle body is typically carried on an extension member, which can be transversely flexible to permit passage of a nozzle body through a tube and along a nonlinear path. The nozzle body is typically connected to an extension member by way of a lap joint associated with the nozzle body. Preferred embodiments have a De /O ratio of less than 12.0, a Db /O ratio of less than about 18, and a Db / De ratio of less than about 1.1. Certain embodiments include a swirling chamber disposed upstream of the ejection orifice and having a proximal wall with a portion configured to at least approximate a portion of a dome, or other curved surface.
