A method and device for blood treatments that use fluids such as dialysate and replacement fluid for renal replacement therapy. In an embodiment, fluid is passed either by pump or passively by gravity feed, through a microporous sterilization filter from a fluid source to a replacement fluid container. The latter forms a batch that may be used during treatment. The advantage of forming the batch before treatment is that the rate of filtering needn't match the rate of consumption during treatment. As a result, the sterilization filter can have a small capacity. In another embodiment, a filter is placed immediately prior to the point at which the sterile fluid is consumed by the treatment process. The latter may be used in combination with the former embodiment as a last-chance guarantee of sterility and / or that the fluid is free of air bubbles. It may also be used as the primary means of sterile-filtration.

An integrally molded display floor for a gravity feed display tray where the floor devoid of integrally molded side walls extending upward therefrom, has front and rear end walls, and a plurality of longitudinal ribs which can receive upward extending partitions which are releasably attachable to the floor and extend longitudinally, thus dividing the display tray into laterally spaced paths. Each display tray has opposite side walls extending downward, and transversely extending beams intersecting the longitudinal ribs. The end walls, side walls, and bottom surfaces of the longitudinal ribs thus establishing a basement where the bottom surfaces of the ribs constitute the ceiling of the basement. This basement is a space suitable for receiving downward extending tabs of the partitions to engage and stabilize such partitions with the display track. The basement also provides suitable space for lateral extending coupling means from one display track to the next for coupling adjacent display tracks to provide a wider transverse area thereof. Furthermore, the basement allows space for further coupling members extending from the rear end of any display track element to the front end of the next for coupling thereto.

A set of panels having chutes therebetween. The chutes being defined by curvilinear rails on such panels. The curvilinear rails having stops thereon for stopping the products for viewing.

A card feed system for feeding cards into a card handling system is disclosed. The system includes a card input department with a playing card support surface, a front wall, a rear wall and two side walls. The playing card support surface slopes towards the front wall at an angle between 12 and 22 degrees. A slot is provided in the front wall to allow single cards to pass into the card handling system. The card feed system also includes a card moving system to advance cards through the slot.

A controller for closed loop control of infusion devices is described. A variety of infusion systems are described that use the closed loop control architecture. In some embodiments the closed loop control may be adapted to current commonly used infusion means such as a gravity feed intravenous system. Other embodiments describe infusion pump system that use biasing or drive mechanisms of springs, elastomers, rotary and linear motors.

A product metering napkin dispenser includes a housing defining a storage magazine for receiving a stack of folded napkins and a metering member that penetrates the stack in order to segregate a predetermined number of napkins from the remainder of the stack for dispensing. Preferred embodiments include gravity feed napkin dispensers. In various embodiments the metering member may include: a pivoting plate cooperating with a hinged trap door support surface; a rotating semicircular disk co-rotating with a support disk; or a reciprocating jaw assembly urging napkins through an aperture.
