  • Patent number: 9889248
    Abstract: A storage tray for one or more syringes includes a recess for each of the syringes to be held in the tray. Each recess has first and second opposed sidewalls that define a space therebetween for receiving the barrel of the syringe. Each of the first and second sidewalls has one or more deformable projections thereon that protrude into the space between the sidewalls for positively retaining the barrel of the syringe between the first and second sidewalls. Additionally, a slot is provided for receiving the thumb rest of the plunger. The slot includes a third sidewall oriented generally transverse to the first and second sidewalls, with the third sidewall including a further projection for engaging a surface of the thumb rest. Preferably, a plurality of such transverse slots is provided to accommodate different positions of the plunger relative to the syringe barrel.

  • Patent number: 8221529
    Abstract: In an embodiment, a dialysis fluid cassette is disclosed. The cassette includes a plurality of walls defining at least one valve chamber, a dialysis fluid inlet, a dialysis fluid outlet and a dialysis fluid pathway. The cassette further includes a baffle extending from a first one of the walls to an opposing second one of the walls. The baffle includes an end fixed to a third one of the plurality of walls and a free end. The fixed end separates the dialysis fluid inlet from the dialysis fluid outlet and the baffle and the plurality of walls are constructed and arranged such that the flow of dialysis fluid along the pathway defined in part by the baffle slows as the flow approaches the free end of the baffle.
