1. A self-retaining nasal tampon comprising an elongated flexible tube open at one end and closed at its opposite end, a hollow self-sustaining bulb carried on said tube adjacent the open end portion thereof, and having a substantially larger diameter than the diameter of said tube, at least one inflatable member surrounding and sealingly attached to said tube remote from said bulb, said inflatable member being free to expand and form an inflated bag, passage means communicating the interior of said tube with said inflatable member to permit inflation thereof by fluid introduced into said tube and said inflatable member via passage means, said bulb being sufficiently rigid to be selfsustaining in the absence of internal pressure and thereby to prevent aspiration of the nasal tampon by a patient whether the inflatable member is inflated or deflated, and sealing means positioned in said tube adjacent said bulb, said sealing means having an inner portion in communication with said passage means and an outer portion located and arranged to permit communication between said inner portion and a source of fluid under pressure to permit inflation of said inflatable member, and to prevent deflation of said inflatable member after inflation thereof, a second inflatable member sealingly attached to said tube and disposed around said flexible tube intermediate the ends thereof and between said first mentioned inflatable member disposed around said closed end of said tube, and said bulb, said second inflatable member being free to expand and form an inflatable bag around the intermediate portion of said tube, said inflatable members being independently inflatable, second passage means communicating the interior of said tube and said second inflatable member to permit inflation thereof by fluid introduced into said second inflatable member, second sealing means positioned within said tube and spaced from said first mentioned sealing means, said second sealing means having an inner face in communication with said second passage means and an exterior face located and arranged to permit communication between said last mentioned inner face and a source of fluid under pressure, to permit inflation of said second inflatable member, and to prevent deflation of said second inflatable member upon inflation thereof.
