Abstract:
1. A method for controlling bleeding in epistaxis patients, comprising: providing an inflatable nasal packing device for an epistaxis patient, the inflatable nasal packing device comprising: an insertion tube comprising three lumen including an air passageway lumen extending the length of the tube with an opening at each end of the tube, a first fill lumen with an inlet at one end of the tube and an outlet in a first portion of the tube, and a second fill lumen with an inlet adjacent the inlet for the first fill lumen and an outlet in a second portion of the tube; a first bag formed of non-elastic, flexible material positioned about the first portion of the tube and sealed to the tube with a pair of spaced-apart circumferential end seals such that the first bag extends along the first portion of the tube substantially parallel to a longitudinal axis of the tube; and a second bag formed of non-elastic, flexible material positioned about the second portion of the tube and sealed to the tube with a pair of spaced-apart circumferential end seals such that the second bag extends along the second portion of the tube substantially parallel to a longitudinal axis of the tube; connecting a first pressurized source to the inlet of the first fill lumen; connecting a second pressurized source to the inlet of the second fill lumen; inserting the nasal packing device into a nasal passage of the epistaxis patient; first operating the first pressurized source to fill the first bag with gas or fluid at a first fill pressure to contact interior surfaces of the anterior nasal cavity of the epistaxis patient; second operating the first pressurized source to pressurize the filled first bag to a first bleeding control pressure higher than the first fill pressure; first operating the second pressurized source to fill the second bag with a gas or fluid at second fill pressure to contact interior surfaces of the posterior nasal cavity and nasopharynx of the epistaxis patient; and second operating the second pressurized source to pressurize the filled second bag to a second bleeding control pressure higher than the second fill pressure.
