Abstract: Probe cover cassettes having a plurality of probe covers releasably attached to a frame are capable of being stacked so that probe covers attached to a first of the frames are nested within probe covers attached to a second of the frames. The vertical space occupied by the cassettes is reduced allowing more cassettes to be stacked in a given space. The frames of the cassettes are particularly constructed to resist twisting and bending motion when probe covers are detached from the frames using a tympanic thermometer probe.

Abstract: An adaptor for discriminating connection of an oral tip of a source of liquid enteral product to a feeding line. In one embodiment, the adaptor includes an internal stop in the body having a contact surface that is angled with respect to a transverse plane extending generally transverse to the longitudinal axis of the connection port so that if the standard luer tip is inserted into the connection port, the luer tip does not make flush contact with the contact surface. In another embodiment, the adaptor includes an external stop surrounding the connection port generally adjacent to the first open end of the body. The adaptor may include an umbrella valve. In other embodiments, the adaptor includes a fluid release opening in fluid communication with the connection port extending generally radially through the adaptor body at a location spaced from the longitudinal ends of the body.

Abstract: A cassette of probe covers that can be removed from the set for covering a probe of a tympanic thermometer can be securely retained in a cassette holder, and readily removed when necessary. The cassette includes a retaining system that can have a detent on the cassette holder and a detent receptacle on the cassette. The detent snaps into the receptacle when the cassette is inserted into the holder. The holder is configured so that grips on the cassettes are readily accessed to grasp and hold the cassettes for removal from the holder.

Abstract: An administration feeding set adapted to be loaded to a flow control apparatus is disclosed. The administration feeding set comprises tubing adapted suitably for fluid flow, a valve mechanism suitable for loading the administration feeding set to the flow control apparatus, and a mounting member adapted suitably for permitting identification of the functional configuration of the administration feeding set. Also disclosed is a method for administering fluid utilizing the administration feeding set. There are also disclosed novel valve mechanisms.

Abstract: A fluid adapter for connection between a valve and a tube having a single lumen includes a housing having a tab. The tab is releasably connected over a secondary port of the valve. The tab is configured to occlude the secondary port to prevent a user from toggling the secondary port. The housing is configured to be releasably connected to the valve.

Abstract: A pump set for use in a liquid delivery pump of the type for delivering liquid to a patient, having an infrared radiation detector for detecting infrared radiation, and providing an indication that the pump set is properly loaded on the pump. The pump set comprises a conduit for the liquid and a safety interlock member which is carried by the conduit.

Abstract: A probe cover for a tympanic thermometer probe comprises a generally tubular body having an opening for receiving the thermometer probe and an infrared transparent window at a distal end thereof. In one embodiment, a film support extends radially inward from the distal end of the body and supports an infrared transparent film spanning the window. The film support has an inner edge that is substantially free from corners turning in the plane of the window. A plurality of end ribs are spaced apart and disposed about an inner circumference of the distal end of the body to engage a distal end of the thermometer probe and form an insulating gap by preventing contact of the film by the thermometer probe. The insulating gap also extends proximally into spaces between the end ribs, reducing thermal contact between the thermometer probe and a circumferential inner surface of the probe cover.

Abstract: A low profile gastrointestinal tube feeding system having a securing member for securing a feeding set to a low profile gastrostomy tube disposed inside a visceral organ of a patient's body so that inadvertent removal of the feeding set from the gastrostomy tube is prevented. Also provided is a securing member that secures a connection member to an external retention member. Once the securing member has connected the connection member to the external retention member, neither the connection member nor the external retention member can be separated from one another until the securing member is first disengaged from either member.
