ABSTRACT:
A nasal hemostat, adapted for insertion into a nasal cavity, is composed of contracted material adapted to expand into a porous tampon upon contact with a fluid. The contracted tampon is in the form of an elongated cylinder. Upon expansion, the tampon assumes a domed shape, having a linear bottom wall, a convex top wall, and two parallel side walls. A substantially rectangular tongue continuous with the bottom wall protrudes from the posterior end of the expanded tampon. Two elongated recesses are formed longitudinally in one of the side walls. Upon expansion, these recesses receive the inferior and middle conchae of the nasal cavity lateral wall so that the expanded tampon will apply hemostatic pressure to substantially all parts of the nasal cavity. The rearwardly extending tongue, when in operative position, preferably terminates short of the pharyngeal orifice of the auditory tube. An elongated breathing tube extends longitudinally through the contracted tampon from the anterior end to the posterior end. The tube is positioned to extend through the tongue at the posterior end to allow nasal breathing when the tampon is expanded.
