Abstract: A water and other fluids supply container is provided for use in the medical field with oxygen humidifiers and nebulizers and the like. Included may be a collapsible plastic reservoir having an attachment mechanism for mating to the mist generating apparatus. An access opening to the interior of the bag above the normal fluid level preferably exists at the attachment mechanism. A passageway may extend into the bottom of the bag to access the fluid located therein.

Abstract: A convertible function water vapor generating device is provided for use with medical oxygen delivery systems for creating a nebulizing mist suspended in the oxygen flow and for creating a bubble humidified oxygen flow. An oxygen handling component may be connected to a refillable and/or disposable water container which may be prefilled and which preferably has a passageway for directly accessing the bottom of the water supply held therein. A heater for heating water accessed may reside as part of the handling component which also may contain a nebulization nozzle and a nebulizer-humidifier function control.

Abstract: An independent, replaceable probe unit for an electronic measuring system having a housing with a compartment for receiving the probe unit, including; a probe member having a probe element bearing a sensor device for sensing the parameter to be measured by the system and a cable electrically connected to the sensor device; and a probe chamber removably mountable in the compartment and having a recess for receiving the probe member, the chamber including contact means interconnected with the cable and disposed to engage corresponding contact means in the compartment for interconnecting the probe member with the electronic measuring system.

Abstract: A nozzle formed by the mating of two separable parts, a housing and a plug insert, having a smaller diameter orifice formed at a first mating interface of these two parts, a Venturi chamber connected to the smaller orifice, being formed at a second mating interface of these two parts and a larger diameter orifice extending through the plug insert part being connected to the Venturi chamber.

Abstract: An intravenous tubing cap for sealing the end of a male tubing coupling or a female tubing coupling is provided by a plug having a tapered male fitting at one end being backed against a tapered female fitting at the other end. The plug may be molded in one piece with the back of the male portion forming a contiguous part of the female portion. Preferably, a serrated protective skirt around the male fitting provides a surface by which the cap may be grasped.

Abstract: A selection valve, creating a minimal flow-through turbulence for use in the administration of three separately supplied intravenous fluids, for selecting with one-handed operation any one of the fluids connected or a mixture of any two fluids adjacently connected, is provided having a body with a cylindrically shaped cavity containing three closely positioned ports and a separately positioned port. A cylindrically shaped rotor may be disposed within the cavity and rotated to position a single passageway part thereof between the outlet and an inlet port. The outlet end of the passageway may be shaped to enable the exposure of the outlet port for any inlet port position. Preferably the valve body is mounted to a support structure which in turn may be secured to an immobile surface.

Abstract: A light inclining accessory for a slit lamp includes a multi-faceted mirror having a top segment for receiving an illumination beam from the slit lamp and directing the illumination beam horizontally toward a focal point coinciding with the eye of a patient and a plurality of additional mirror segments having varying angles relative to each other, and a light directing device pivotally mounted on the slit lamp to be positioned to intercept the illumination beam and selectively adjustable to direct the illumination beam toward the additional mirror segments such that the illumination beam can be directed toward the focal point at various angles of inclination.

Abstract: Photographic apparatus for a slit lamp includes a photographic camera adapted to be mounted on one ocular of a binocular microscope of the slit lamp and a light sensing device positioned adjacent an objective of the microscope for providing a signal corresponding to light at the objective to an automatic exposure control mechanism in the camera, the other ocular of the microscope being free to permit viewing of an object being photographed.
