Abstract: An anti-microbial air processor is configured and arranged to fit at least substantially across an airway in a personal patient-warming apparatus to thereby inactivate airborne microbes before those airborne microbes are exposed to a patient via warming air delivered by the personal patient-warming apparatus. By one approach, the anti-microbial air processor comprises an anti-microbial air filter. By another approach, in lieu of the foregoing or in combination therewith, the anti-microbial air processor comprises one or more ultraviolet light sources configured to expose at least one inner surface of the personal patient-warming apparatus to ultraviolet light to thereby inactivate microbes.

Abstract: To provide radio-frequency (RF) bandstop filtering within an implantable lead, such as a pacemaker lead, one or more segments of the tip and ring conductors of the lead are formed as insulated coils to function as inductive band stop filters. By forming segments of the conductors into insulated coils, a separate set of discrete or distributed inductors is not required, yet RF filtering is achieved to, e.g., reduce lead heating during magnetic resonance imaging (MRI) procedures. To enhance the degree of bandstop filtering at the RF signal frequencies of MRIs, additional capacitive elements are added. In one example, the ring electrode of the lead is configured to provide capacitive shunting to the tip conductor. In another example, a capacitive transition is provided between the outer insulated coil and proximal portions of the ring conductor. In still other examples, conducting polymers are provided to enhance capacitive shunting. The insulated coils may be spaced at ¼ wavelength locations.

Abstract: Anti-spray fluid dispensing nozzle for filling an open top container. The nozzle comprises an elongated fluid supply conduit establishing a fluid path between a source of pressurized fluid and the container to be filled. First and second valves are mounted in the supply conduit disposed in a spaced apart relationship with the first valve positioned upstream the second valve. Each valve includes a movable closure member cooperating with a valve seat to control the flow of fluid through the supply conduit. The closure members of both valves are coupled to a common actuating rod mounted for linear movement within the supply conduit to selectively displace each closure member between a valve closed position and a valve opened position.
