Abstract
The nasal packing device includes a splint portion, an airway member secured to the splint portion and a flexible expandable membrane secured to the airway member. An inflation chamber is thus defined between the flexible expandable membrane and the airway member. Under this arrangement, expansion of the membrane is in a direction away from the airway member enabling the membrane to provide a substantially uniform pressure against the splint portion and against any portions of the nose which the membrane comes into contact with. A uniform compressive force provided by the expandable membrane is thus attainable within the nasal passageway to arrest intranasal bleeding, while the splint supports the septum and the airway member allows nasal breathing.
