摘要: A syringe adapter includes an outer housing having a sidewall defining an interior space, a membrane housing positioned within the interior space of the outer housing and moveable from a first position within the outer housing to a second position within the outer housing spaced from the first position, with the membrane housing receiving a membrane, a needle hub connected to the outer housing and configured to be connected to a syringe, with the needle hub rotatable relative to the outer housing, and a needle connected to the needle hub. The needle having a first end and a second end positioned opposite the first end, with the second end of the needle received within the membrane when membrane housing is in the first position. The needle is rotatable relative to the needle hub.

摘要: A connector assembly may include a cover defining a cavity, a luer portion extending through an open end of the cover, a proximal connector disposed at least partially in the cavity of the cover, a pusher mounted on the proximal connector, a distal connector at least partially disposed in the cover, and a stopwatch mounted on the cover and including at least one contact. The pusher may include a body portion and first and second pusher legs extending from the body portion. When the distal connector is coupled to a mating connector, the stopwatch may abut the first pusher leg such that the at least one contact is recessed within the stopwatch. When a force applied to the proximal connector exceeds a predetermined threshold the stopwatch may be separated from the first pusher leg and the at least one contact may extend proximally to activate a timer of the stopwatch.

摘要: Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.

摘要: A fluid handling cassette, such as that useable with an automated peritoneal dialysis (APD) cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber formed as a depression in a first side of the body and a plurality of flowpaths for a fluid that includes a channel. A patient line port may be arranged for connection to a patient line and be in fluid communication with the at least one pump chamber via at least a first one of said flowpaths, and an optional membrane may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion with an unstressed shape that generally conforms to the depression of the at least one pump chamber in the body and is arranged to be movable for movement of the fluid in a useable space of the at least one pump chamber. One or more spacers may be provided in the at least one pump chamber to prevent the membrane from contacting an inner wall of the at least one pump chamber. The patient line, a drain line, and/or a heater bag line may be positioned to be separately occludable in relation to one or more solution lines that are connectable to the cassette.

摘要: A connector system for medical fluid includes a male connector and a female connector that have a closed configuration when detached from one another. The first end of the male connector is configured to mate with a first end of the female connector. When the male connector is coupled with the female connector, complementary structures engage to move seals away from ports in the male connector and the female connector, opening a fluid pathway through the connectors. The mating ends of the connectors are not exposed to the medical fluid when the connectors are coupled so that when the connectors are disconnected, the mating ends are substantially free of residual medical fluid.

摘要: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

摘要: A self-cleaning needleless connector may include a connector body defining a fluid passageway including an inlet and an outlet, a cover disposed over at least the inlet of the connector body, an access point disposed at an inlet end of the cover, where in a first position the inlet is within the cover and in an second position the inlet is extended beyond the cover and configured to receive a male luer, a reservoir containing a cleaning agent, and an abrasive surface located in the cover that is in fluid communication with the cleaning agent, where the abrasive surface and the cleaning agent are configured to contact an exterior surface of the inlet to create friction.

摘要: An apparatus is provided for connecting and disconnecting a tubular fitting connector to a fluid conduit. A cradle assembly accommodates the fluid conduit, and includes a body having a first port and a second port. The first and second ports are disposed at opposite ends of the body, and each port is configured for receiving an end cap of the tubular fitting to fasten or unfasten the end cap for replacement. A connector holder is disposed between the first and second ports, and is configured for accommodating insertion of the connector. A holder assembly is provided for accommodating insertion of the tubular fitting. A means is provided for operating the cradle assembly and the holder assembly. The cradle assembly is reciprocable relative to the holder assembly for transitioning the cradle assembly between a first position, a second position, and a third position.
