Abstract: A nasal lavage device includes a source of saline solution, an effluent receptacle, and a nasal interface for engaging the nostrils of a user of the device. A fluid passageway is disposed to communicate the source of saline solution with the effluent receptacle through the nasal cavity of the user. The nasal interface and fluid passageways are included within a removable cartridge for communicating the saline relative to the nostrils in a first direction. A second cartridge can be inserted to communicate the flow in a second direction. The interface includes nasal pillows that form a seal against the user's nostrils.

Abstract: A method of manufacturing flow selector disk for a fluid pressure regulator, including the steps of providing a plate having a first face and a second face, and forming at least one baseline orifice in the plate including a first diameter portion adjacent the first face and a second diameter portion adjacent the second face. The first and second diameter portions are spaced a distance from each other to form an annular ring therebetween. A central flow portion is formed through the baseline orifice that is in fluid communication with both of the first and second diameter portions. The central flow portion has a relatively smaller diameter than either of the first and second diameter portions. The method also includes the step of plastically deforming a portion of the annular ring adjacent the central flow portion to thereby reduce the diameter of the central flow portion.
