    Abstract: The thermal isolation apparatus for the protruding probe of a biomedical thermometer includes an insulative air gap and a heat sink disposed between the surface of the probe and the optical path through the probe. The heat sink surrounds the optical path, such as a waveguide, and acts to evenly distribute any heat along the entire length of the waveguide to avoid temperature variations. Additionally, the heat sink has sufficient mass for high heat capacity and may slow the progress of any heat from reaching or leaving the waveguide until after the measurement by the biomedical instrument has been completed. Disposed over the heat sink is a boot which forms the closed air space between the heat sink and the outer probe surface. The air gap combined with the heat sink provide relative thermal isolation of the optical path through the probe and provide relative thermal isolation of the target anatomy from the temperature of the probe.

    Abstract: A fluid filter is disclosed for use in filtering intravenous fluids as they are administered to a patient. The unique filter employs a normally hydrophobic (water-repellent) depth-type filter element, which has a sufficiently large pore size and volume of pores to permit an adequate gravitational flow of intravenous fluid from an elevated reservoir. Particulate matter is filtered out by the tortuous passageways in the filter element, through which liquid must pass. Due to the relatively large pore size (20 microns or larger) of the filter element, in combination with the normal hydrophobic property, any gas entrained in the liquid also passes through the filter element and does not accumulate on the filter surface to block flow therethrough--so called "air blocking".

    Abstract: A superior friction material having high mechanical fatigue resistance and a stable dynamic coefficient of friction over a wide temperature range is prepared from an intimate mixture of an epoxy-rubber binder and friction modifying materials. The material is formed by mixing the uncured epoxy resin with the rubber and friction modifying materials, forming the mixture into the desired shape while soft and pliable, and then heat curing the mixture.

    Abstract: A medical valve assembly comprises a valve body having a fluid passage therethrough, a valve member, and an urging means disposed within the fluid passage. The valve member is adapted to seal against a sealing surface of the fluid passage and the urging means is adapted to urge the valve member against the sealing surface. The medical valve can be used without a needle thereby eliminating risks associated with needle stick injuries. In applications where it is expedient to use a needle (such as prepackage medications) the medical valve accommodates the use of a needle to administer medication. The urging means is disclosed in a first embodiment wherein it is formed integral with the head portion of the valve member. In an alternative embodiment, the urging means is separate from the head portion of the valve member and is comprised of a metallic spring element.

    Abstract: The protective apparatus for a biomedical thermometer having a protruding probe containing a waveguide includes mounting a transparent window at the patient end of the waveguide to seal the waveguide from contamination while permitting infrared energy to pass. A protective sleeve protects and mounts the transparent window to the waveguide and material is provided along the entire probe-length of the waveguide to protect it. An outer boot is mounted over the transparent window and waveguide protection material to provide further protection and to supply a mounting and retaining surface for a protective probe cover. A disposable protective probe cover having a generally thin, flat, frame member with an aperture therethrough, is sized to fit over and be retained over the base of the probe by a friction interference fit. Extending across the aperture of the probe cover frame member is a material which stretches to generally conform to the shape of the probe when the tip of the probe is inserted through the aperture of the frame. A probe cover sensor is provided to indicate the existence of a protective probe cover.
