摘要： A fluid tube is disclosed herein. The breathing circuit tube has a wall which comprises a hollow geometry. The wall defines a passageway with a central longitudinal axis therethrough. The wall is expandable and contractible to adjust a diameter and a length of the passageway. The wall includes one or more corrugations that expand and contract to adjust the diameter and length of the passageway. The corrugations extend between terminal end portions of the wall.

摘要： A fluid trap apparatus includes an inlet configured to receive a flow of composite fluid into the apparatus. The composite fluid contains at least a first fluid and a second fluid. An outer wall defines an interior chamber. A flow diffuser is interposed within the interior chamber. The flow diffuser directs the flow of the composite fluid to circulate through the interior chamber. The first fluid and the second fluid separate as the composite fluid circulates through the interior chamber. A method of separating a first fluid from a second fluid includes introducing a flow of composite fluid into a separate chamber. A pressure gradient is created within the separation chamber. A flow diffuser is interposed in a flow path between an inlet and an outlet. The flow diffuser directs the flow of the composite fluid within the separation chamber. The first fluid and the second fluid are separated.

摘要： A fluid trap is disclosed herein. The fluid trap has a tube connector defining a first interior passageway and a second interior passageway. The tube connector is adapted for connection with a dual lumen tube such that the first interior passageway is in fluid communication with one of the dual lumen and the second interior passageway is in fluid communication with the other of the dual lumen. The fluid trap also includes a reservoir operatively connected to the tube connector. The reservoir is in fluid communication with only one of the interior passageways, and is configured to retain fluid from that passageway.

摘要： An apparatus for coupling to a fluid delivery system and for receiving a fluid into the apparatus; a portion of the apparatus permitting a change in shape or size to accommodate the fluid volume or pressure received therein. The apparatus including a housing with a cavity, an expandable reservoir with an opening and a passage, and a cap; the expandable reservoir positioned within the cavity and coupled to a fluid source. The expandable reservoir includes an unrestrained orientation when a fluid volume or pressure therein is below a threshold, and an expanded orientation, when the fluid volume or pressure therein is above the threshold; the expandable reservoir moving toward the expanded orientation to accommodate a fluid volume or pressure received through an opening, and the expandable reservoir moving toward the unrestrained orientation to direct a fluid volume or pressure through an opening.

摘要： A slide clamp for use with an infusion pump and infusion set provides finger grips and support members for supporting the infusion tubing. The finger grips make the slide clamp easier to use while reducing the risk of error. The tubing support members reduce the likelihood of improperly loading the tubing and reduce the risk of kinking the tubing during use. An infusion set is provided wherein the slide clamp may be coded through the use of colors, holes, or the like so as to identify the type of infusion tubing used therewith. The infusion pump can identify the code on the slide clamp and thereby determine the type of infusion tubing, and thereby allow access only to infusion programs for drugs or infusion solutions which are compatible with the particular type of infusion tubing.
