Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

Abstract: Hemodialysis and similar dialysis systems including a variety of systems and methods that make hemodialysis more efficient, easier, and/or more affordable, and include new fluid circuits for fluid flow in hemodialysis systems and a reciprocating diaphragm pump for pumping fluids. The reciprocating diaphragm pump includes a flexible diaphragm, a first rigid body having a curved pumping chamber wall, a second rigid body having an opposing curved control chamber wall. The diaphragm is interposed between the pumping chamber wall and the control chamber wall to define a pumping chamber and a control chamber. The diaphragm of the pump has a peripheral bead arranged to locate the diaphragm between the first rigid body and the second rigid body and a diaphragm body having a curved, semi-spheroid or domed shape.

Abstract: A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

Abstract: Systems and methods for a sterile imaging protective system are described. The system preferably includes a first flexible drape with a cavity configured to surround an imaging intensifier and a second drape that is attached to an operating table or patient drape. The second drape has a proximal portion, a distal portion, a pocket therebetween with a top sterile portion and a lower portion, and a plurality of reusable fasteners that allows the second drape to be repeatedly moved from a collapsed configuration to an expanded configuration. When in the expanded configuration, the second drape is releasably attached to the first drape. The system may also include a third drape located on the opposite side of the operating table as the second drape. The drapes preferably allow sterility to be maintained during movement of the c-arm imaging system.

Abstract: Systems and methods for using a sterile drape with a surgical table are described. The system includes a sterile drape and at least one securement device that secure the sterile drape to the surgical table. The securement device may be an adhesive sticker having a perforation. Because of the perforation, the sticker is prone to break under small levels of force exerted on the sticker. In this way, a user can visually determine whether potential breaches of sterility have occurred when the sticker has broken. Additionally, the system may include magnets, weights, poly-ties, rubber bands, hooks, clips, buckles, adhesive tabs, straps, tape, and the like to secure the sterile drape to the surgical table. In this way, the surgical table can be prepared, the sterile drape can be installed, and the drape can be secured to the table to prevent breaches of sterility.

Abstract: A flip-to-wear eye shield system is provided. By integrating a hinge into elements of the frame and/or the lens, the eye shield can be manufactured and assembled more quickly and with less costs. In an embodiment, a lens may click (or snap) onto molded posts of a frame in a substantially flat position. An integrated living hinge in the frame may bend to allow the lens to flip downwards toward the frame to a second position for use. The posts may also click (or snap) into place in an underside of the frames. In another embodiment, a lens may click (or snap) onto molded posts of a flame in a substantially flat position. An integrated living hinge, formed by notches in the lens, may allow the lens to bend to flip downwards to the frame to a second position for use. A dispenser allows storing the eye shields in the flat position and dispensing in the second position for use.

Abstract: A disposable face shield with a shield with a plurality of cuts is described. A foam member is connected to the shield to provide added comfort. The foam member may contain a plurality of openings extending through the member. The openings allow for increased air movement around the shield. The cuts in the shield may be above the foam member to create tabs which may be bent to at least partially cover the openings that extend through the foam member. Additionally, a pair of parallel cuts may be made on either side of the shield, the cuts adjustably engaging an elastic strap. This configuration allows the elastic strap to be comfortably adjusted to conform to a number of different sized heads.
