Peritoneal dialysis systems and methods are provided by the present disclosure. In a general embodiment, a peritoneal dialysis system includes a peritoneal dialysis fluid supply, a supply line in fluid communication with the peritoneal dialysis fluid supply, the supply line terminating at a supply connector, a patient connector in fluid communication with a patient's indwelling catheter, and a device configured to be placed around at least one of the supply connector and the patient connector during a connection of the supply connector and the patient connector, the device including an ultraviolet ('UV') transmissive material to allow UV energy to be directed inwardly through the device towards a mating surface of the at least one of the supply connector and the patient connector during the connection of the supply connector and the patient connector.

Peritoneal dialysis systems and methods are provided by the present disclosure. In a general embodiment, a peritoneal dialysis system includes a peritoneal dialysis fluid supply, a supply line in fluid communication with the peritoneal dialysis fluid supply and terminating at a supply connector, a patient connector in fluid communication with a patient's indwelling catheter, a device configured to connect the supply connector to the patient connector without a user having to physically contact the supply connector or the patient connector, and a housing placeable around the connecting device and including a plurality of ultraviolet ('UV') light-emitting diodes ('LED's') positioned to direct energy towards at least one of the supply connector and the patient connector.

Peritoneal dialysis systems are provided by the present disclosure. In a general embodiment, a peritoneal dialysis system includes a cycler, a disposable cassette operable with the cycler, a supply bag connected to the disposable cassette, a supply connector, a supply line extending from the disposable cassette, a patient connector in fluid communication with a patient's indwelling catheter, a device to connect the supply connector to the patient connector, and a housing around the device. The housing includes a plurality of ultraviolet ('UV') light-emitting diodes ('LED's') for directing energy towards at least one of the supply or patient connectors. The LED's are configured to deliver about 200 milliJoules in a period of about a minute.

A light applicator for a peritoneal dialysis conduit connection includes a housing having a inner surface; a plurality of ultraviolet ('UV') light-emitting diodes ('LED's') positioned on the inner surface of the housing; and circuitry connected to the UV-LED's such that power can be supplied to energize the UV-LED's simultaneously.

An open seal check system for a multi-chamber supply container having at least one elongated seal, the system includes: (i) a base configured to support the multi chamber container; (ii) a plurality of electrodes positioned on the base so as to be at least substantially parallel with the elongated seal; and (iii) electronics connected to the electrodes, the electrodes each forming a capacitor with the multi-chamber supply container when the container is placed on the base, the electronics configured to output a single indication of a dielectric associated with each capacitor.

Apparatus and method for verifying a seal between multiple chambers

In a cross finned tube heat exchanger including a multiplicity of side-by-side fin plates, and a plurality of heat transfer tubes extending through the fin plates at least in one row to provide a serpentine flow passage for a heat transfer medium which exchanges heat with another heat transfer medium flowing across the surfaces of the fin plates, a multiplicity of stepped louvers are formed on the wall of each fin plate between the adjacent heat transfer tubes of the same row. The stepped louvers each extending in a direction at right angles to the direction of air flow across the surfaces of the fin plates include at least one tilting rise wall and may differ from one another in shape depending on their positions. The stepped louvers on each fin plate may be arranged in the form of waves or uniform in height with respect to the direction in which each fin plate extends. The adjacent stepped louvers have edges varying in vertical positions.

Heat exchanger

A cross-fin tube type heat exchanger having a large number of parallel fins and a plurality of heat transfer tubes extended through and fixed to the fins, so that heat may be exchanged between a first heat exchanging medium flowing through the heat transfer tubes and a second heat exchanging medium flowing along the surfaces of the fin, across the walls of the heat transfer tubes and through the fins. In the portions of each fin between adjacent heat transfer tubes of the same row, formed are a number of slits perpendicular to the direction of flow of the second heat exchanging medium. Each elongated section defined between each pair of adjacent slits is bent along its breadthwise bisector line and is raised in the form of a bridge to constitute an upwardly convexed louver element. The upwardly convexed louver element may have a cross section with an obtuse apex angle, or may have an arcuate cross section. The successive louver elements are arrayed in the direction of flow of the second heat exchanging medium in a manner of corrugation, or alternately staggered in the heightwise direction so that the edges of adjacent louver elements may be staggered in the heightwise direction. The fins having louver elements thus constructed cause a turbulency of the flow of the second heat exchanging medium to effectively prevent boundary layers of the latter from growing, thereby to ensure a higher efficiency of the heat exchange. Also increased stiffness or rigidity of the fin is obtained thanks to the provision of upwardly convexed louver elements.

Automatic molten metal pouring apparatus comprising molten metal level detector, mold position detector, ladle tilting angle detector, a ladle tilting servomechanism and a control device. The apparatus permits a suitable pouring flow rate of molten metal to be automatically poured into each of the molds of different types which may be conveyed one after another to the pouring position along the casting line.

Automatic molten metal pouring apparatus

A molten metal pouring device is disclosed, wherein there are provided two pairs of link mechanisms whose links are adapted to be moved in parallel relation to each other, so that, regardless of an inclined angle of a ladle, a molten metal-dropping locus may follow a constant path when a molten metal is poured from a ladle into a mold. The molten metal pouring device equipped with these link mechanisms can be readily automated, as well as permits the reduction in cross sectional area of a sprue of a mold. Thus, temperature drop of a molten metal is avoided, with the result of production of castings of an improved quality.
