Powered irrigator for sinus cavity rinse

摘要

A powered irrigator for use in rinsing nasal cavities has a main body including a handle and a fluid reservoir detachably coupled to one another, an outlet nozzle extending from a top end of the handle, a pump mechanism operably coupled to a power source, and a switch operably coupled to the power source for turning the pump mechanism on and off. When the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle. The top of the handle can be angled relative to a longitudinal axis of the main body. The nozzle is removable from the top end and has a self-sealing structure to provide an enhanced fit within a user's nostril.

1. A powered nasal cavity irrigator comprising
a rigidly constructed main body having a handle and fluid reservoir, wherein the handle and the fluid reservoir are detachably connected to each other; an outlet nozzle extending from a top end of the handle; a pump mechanism operably coupled to a power source; and a switch operably coupled to the power source for turning the pump mechanism on and off, wherein the switch is arranged at an external surface of the handle; wherein when the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle; the pump has a cycle rate between 2,000 to 3,000 cycles per minute; and the fluid exits the outlet nozzle at a pressure of approximately 5 pounds per square inch and at a flow rate between 500 to 600 milliliters per minute.
