Inflatable nasal packing device with two non-elastic, flexible bags oversized relative to nasal cavities

摘要

An inflatable nasal packing device, and method of use, for insertion in a patient's nasal cavity to control bleeding or epistaxis. The device includes a flexible insertion tube, a first inflatable bag attached to and surrounding an anterior section of the tube, and a second inflatable bag attached to and surrounding a posterior section of the tube. The tube has three lumens for providing separate fill passageways to the two bags to allow independent filling and pressurization and for providing an air passageway through the device even when the bags are inflated. Both bags have walls of non-elastic, flexible material with fixed surface areas defining interior volumes when inflated that are larger than the anterior nasal cavity and the posterior nasal cavity and nasopharynx.
