Abstract: A port/catheter tube assembly which insures a stable essentially inseparable connection between the hollow male outlet stem of the port and the proximal end of the catheter tube, thereby insuring a continual supply of medication to the desired patient site while preventing inadvertent harm caused by unintended leakage of such medication into improper tissue sites due to separation of the catheter tube from the port or due to kinking.

Abstract: A novel hyperbaric oxygenation apparatus, and related methods, the apparatus comprising a chamber in the form of a disposable inflatable bag of impervious inexpensive synthetic resinous material which can be used at any desired location, such as a hospital, a home or other site where oxygen can be appropriately made available. The pressure of the oxygen in the collapsible bag is pulsated between maximum and minimum positive values. The patient cyclically experiences first a medicinal increase in the blood gas levels in the limb under treatment with a corresponding restricted blood flow and, thereafter, a progressive return to normal blood flow rates in the limb of the patient as the pressure in the chamber changes from maximum to minimum positive pressure. A respirator, normally used for intubated respiratory patients, in conjunction with a single oxygen influent/effluent port in hyperbaric oxygenation apparatus is efficacious to provide the oxygen and generate the desired pressure variations.

Abstract: A self-feeding dog feeder that has a capacity for several days feeding, constructed in such a way that the feed is protected from inadvertent contamination or loss, while still allowing easy access by the desired dog only.

Abstract: Dilator/sheath assemblies for unstressed placement of catheter tubes into a body cavity of medical patients, which insure a stable axial relationship between concentrically superimposed sheath and dilator so that use is very facile for the medical attendent and insures a predetermined two-step gentle enlargement of a puncture site to accommodate unstressed placement of a catheter tube into a vein or artery through the puncture site and with minimal trauma to the patient.

Abstract: A receptacle for a pencil, tool or the like which is initially slidably carried upon a workman's suspender strap by use of loops. Typically, after the suspenders have been adjusted and sized to fit the body and suit the preferences of the workman intending to use the suspenders, the receptacle is axially displaced along and relative to the associated suspender strap until a location satisfying the desires of the workman is found whereupon the receptacle is stationarily anchored by one or more fasteners to the chosen suspender site so that inadvertent relative axial displacement thereafter is prevented.

Abstract: Catheter tubes of elastomeric material having novel lumen shapes which prevent occlusion and accommodate continued liquid flow even when kinked. Also, catheter tube slit valves are disclosed, the walls of which are not chemically weakened. Symmetrical and asymmetrical versions of said slit valves are disclosed. Combinations of highly reliable slip valves and catheter tubes are disclosed. Independently operable multi-lumen catheter assemblies of synthetic material, such as silicone rubber are disclosed, wherein the distal end of each lumen is normally closed by a three-position slit valve formed in a catheter tube covering.

Abstract: A percussor for respiratory percussion therapy, comprising a lightweight flexible cantilever handle and a soft elastomeric percussion cup secured to the distal end of the handle. The bell-shape of the percussion cup provides a highly effective percussion shock wave and sound, while accommodating a wide range of striking forces and angles relative to any desired body surface. A lip having a large surface area substantially avoids irritation, trauma and injury to the patient.

Abstract: Low cost medical micro pipette tips for difficult to reach places, and related methods. The leading or distal portion of the micro pipette tips are materially elongated and ultra thin. This accommodates placement of the distal influent port, for receiving expensive biological extracts, in hard to reach places.

Abstract: Catheter of soft, flexible material is formed with closed end. Fluid opening formed by single slit through tubing wall of such length that valve will open only upon application of predetermined pressure differentials. Removable stiffener member is positioned in catheter, abutting closed end to push catheter into body vessel when inserting.

Abstract: A ventilating and aspirating assembly comprising an aspirating catheter tube internally disposed within and coextensive with a surrounding flexible collapsible sterility preserving film envelope, a connector by which ventilating air is involuntarily delivered to and exhausted from the lungs of a medical patient, said connector comprising structure which accommodates the manual insertion of the catheter tube into and manual removal from the trachea/bronchi patient through the connector. This facilitates aspiration of undesired respiratory fluids.

Abstract: A molded synthetic electrical box formed of synthetic resinous material preferably using one-piece molding techniques is mountable in walls and ceilings for enclosing the ends of sheathed electrical conductors connected to a switch or socket within the hollow interior of the box. The electrical box has an integrally molded flange extending around the outside of the walls of the box and parallel to an open front face. The flange is set back from the open face so that the open face will be flush with the interior surface of an interior wall. The flange is capable of being secured to the wall material or to a vapor and air barrier of the building wall by, for example, a suitable adhesive so that moisture and air can not cross the box. The box is further provided with alignment spacers so that it can be alignedly mounted to a surface in a rigid building wall surface.

Abstract: A jig or bench for holding a ski in any one of several stationary positions for servicing and repair comprising a rigid frame without any moving parts or clamps, which provides three stable sites for stationarily supporting a ski in any one of a plurality of positions suitable for different servicing and maintenance operations.

Abstract: The foam dispensing device is intended for use in the inverted position and includes a container having a reservoir portion for holding a foamable liquid and a bellows portion for holding air. A foam producing unit is mounted in the discharge port, the foam producing unit including a housing mounted in and receiving air from the bellows and a liquid receiving conduit extending from the foam producing unit into the reservoir. A separate air return conduit communicating with atmosphere extends into the container air. The container reservoir and bellows portions are separated by a finger-engageable waist portion to facilitate operation of the bellows portion.
