    摘要： According to embodiments, priming systems, methods, and devices are disclosed which allow medical treatment devices which pump fluid to be primed with minimal operator intervention and a high level of convenience. A blood circuit with a filter fitted with one or more air vents on a non-blood compartment is attached to a treatment system and priming fluid pumped slowly through the blood circuit in a loop. The source of fluid may be elevated, or the pumping may generate pressure, such that priming fluid is forced through the membrane of the filter and out the air vent(s). In embodiments, the vents are hydrophobic which prevent fluid from being ejected, so the priming system can run without intervention.

    摘要： A pressure measurement pod for use in blood circuits includes a pressure sensing pod defining a chamber and having a rigid wall portion and an integral flexible wall portion forming a flexible, moveable, fluid-impermeable diaphragm with a first major side thereof facing an interior of the chamber and a second major side opposite the first major side. The second major side faces outwardly away from the chamber, and the pod has ports on sides of the chamber. The internal surfaces of the chamber and ports are shaped such that any contour following the internal surfaces to the outside of one of the ports traces only surfaces characterized by positive or neutral draft angles such that invasive mold portions may be withdrawn through the ports thereby permitting the pressure measurement pod to be molded in a single shot molding process.

    摘要： A needle set includes a needle guard and a winged needle. The needle guard has upper and lower jaws, each of the upper and lower jaws defining a channel and coming together at a hinge. The upper and lower jaws are separated by slots in sides of the needle guard, which slots divide the sides into upper and lower side walls, respectively. The winged needle can be inserted between the upper and lower jaws, with wings of the winged needle passing through the slots. The hinge has an opening and a tube connected to the winged needle passes through the opening.

    摘要： An automated peritoneal dialysis system provides both cycler-assisted peritoneal dialysis treatment and also continuous ambulatory peritoneal dialysis (CAPD). The system includes a fluid preparation and treatment device with a concentrate dilution components connected to a source of purified water and medicament concentrate. The treatment device has at least one mixing container connected via a pump and valves to the sources, the valves and the pump mixing and diluting the concentrate to form a medicament. An auxiliary port is provided for attaching a CAPD container and for receiving medicament. A controller is programmed to control the fluid preparation and treatment device to implement one or more cycler-assisted peritoneal dialysis treatment cycles using medicament from the mixing container and also to control the preparation of additional dialysate at the end of the cycler-assisted peritoneal dialysis treatment cycles to dispense additional dialysate through the auxiliary port for use in CAPD.

    摘要： The disclosed subject matter includes embodiments of fluid couplings that prevent or discourage misconnection of fluid lines. In embodiments, a coupling device may be configured according to lookup table that defines compatible configurations of connectors. The configurations may be based on the presence and absence of interference members at standardized locations on the respective connectors. The interference members may include posts that mechanically interfere with other posts, but can be inserted into holes when two connectors have a compatible configuration.
