Abstract: A novel method and apparatus for manufacturing magnet wire in a continuous process by which coatings of a flowable resin material may be applied concentrically to a moving elongated filament in thicknesses of about 16 mils or less. The filament can be a bare copper or aluminum conductor having round or rectangular configuration or an insulated conductor upon which a top or an intermediate coat of material is desirably applied. Coatings of one-half mil and one mil also can be applied by the method of the invention. By the method and apparatus of the invention, magnet wire can be manufactured by continuously drawing the wire to size, annealing the wire, if necessary, insulating the wire with one or more coats of flowable resin material, curing the resin material, if necessary, hardening the resin material, and spooling the wire for shipment, without interruption at speeds limited only by the filament pay-off and take-up devices used.

Abstract: A low bulk nasal cannula providing consistent gas delivery with greater comfort for the patient is described. The cannula of the present apparatus is made of very soft vinyl material to provide greater comfort. The present apparatus utilizes two extending prongs from a central housing to provide gas to nasal passages. Formed on the end of each prong is a laterally hollowed cylindrical post with a convex excurvated tip. This tip allows the cannula to "float" in the nares of the patient's nose to provide proper positioning of the cannula without requiring a "pinch" fit. Since the tips are only formed on one side of each prong, occlusion of the nasal passages during inhaling and exhaling is substantially reduced. The prongs of the cannula are coupled to a cylindrical hollow housing for providing access to the gas source. A firm plastic ridge is formed along the length of the housing and orthogonal to the extended prongs.

Abstract: A connector valve assembly for admission of catheters through endotracheal tubes employs a connector body having a tracheal tube port, a respiratory tube port and an end portion adapted for insertion of a catheter through the body and through the tracheal tube for patient airway suctioning. An end cap on the end portion has an aperture with a ring seal for sealably engaging the catheter as it is inserted therethrough and has a check valve disposed inwardly of the ring seal toward the respiratory and tracheal tube ports. The end cap defines an air lock chamber for insertion of the catheter through the connector body without interrupting positive pressure ventilation of the patient.

Abstract: A device for delivering gas to a patient comprises a unitary mask member for overlying the patient's nose and mouth and having an upper peripheral surface for lying in sealing engagement against the nose and cheeks, and a lower peripheral surface contiguous therewith disposed outwardly from the face, and a gas delivery member extending along the mask interior having orifices for delivering gas.

Abstract: A bi-flow nasal inhalation cup for mixing oxygen and ambient air includes a crescent shaped cup member or open top receptacle having a recessed pocket in a downwardly sloping collecting floor. A curved inner wall extends above and below a cup floor inner margin and is contoured to gently engage the upper lip of a patient. Opposite wing portions extend outwardly from the inner wall and conform to facial portions laterally of the nose. A substantially vertical outer wall merges with the cup floor and the inner wall and has a center portion which extends above the inner wall and merges with diverging opposite straight arm portions. A pair of cannula inlets respectively extend tangentially through the arm sections and project generally radially outwardly and at an upward angle toward the patient's face. Tubes or cannula are fitted into the inlets and extend toward the patient's face with each tube or cannula having a curve for draping over the patient's ears and supporting the cup member thereby.
