Abstract: A nasal hemostat adapted for insertion into a nasal cavity by individuals not trained in medical or nursing arts 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 rectangle. Upon expansion, the tampon assumes the shape of a small, right-angled triangle adjacent to a truncated isosceles triangle, connected by a common top, having a linear top wall and two parallel side walls. Upon expansion, the tampon will apply hemostatic pressure to substantially all parts of the most important area of the nasal cavity in regards to hemorrhage. Furthermore, the shape of the tampon is such that there should be essentially no waste from the raw material used in the manufacture of said tampon, thereby greatly decreasing manufacturing costs and allowing the tampon to be more readily available to the nonmedical public.

Abstract: A Large Scale Integration (LSI) data flow component is described for use as a building block, the component being capable of use singly or in combination to provide data flow paths and functions of different data widths for a processor or microprocessor. A component with an eight-bit data flow is described as a "byte slice", wherein individual byte control is provided within a multiple-byte configuration so that single data flow components within the group can operate independently of other components under control of external logic. Components may operate on a stand-alone, a multiple-byte, or nonactive-byte basis. A control scheme permits functions of one component to be influenced by actions or logic of another component to permit efficient implementation of arithmetic algorithms.

Abstract: A method is provided for cutting and removing sutures with a thin, flat blade mounted on one end. The blade has a sharp, concave cutting edge and a flattened, convex bearing edge. The cutting and bearing edges converge to a sharp point at the first end of the blade and diverge towards a second end of the blade. The arc of the bearing edge is substantially equal to or less than the arc of the cutting edge. A handle is secured to the second blade end and an obtuse angle is formed between a line drawn parallel to the longitudinal axis of the handle and a line tangent to the bearing edge at the point. The blade cuts sutures as the sutures are lifted from the sutured surface by the blade being rotated away from the sutured surface and linearly advanced.

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.

Abstract: A one piece plastic nasal splint is presized to fit the nasal passage, an isthmus bridging the columella to provide anterior fixation while a single suture provides posterior fixation.
