Abstract: An apparatus comprising a hemodialysis system and a control interface configured to allow user control of the hemodialysis system. The hemodialysis system comprises a housing that includes a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer. The housing includes side-by-side doors that when opened provide access to a front panel for connecting the dialyzer and for making patient blood connections to the hemodialysis system. The doors are closable to block access to the front panel. The control interface includes a display screen with a touch sensitive overlay to allow interaction with a graphical user interface presented on the screen. The control interface is configured to be hung on a hook of one of the doors.

Abstract: An enclosure for containing a hemodialysis unit includes a housing (51) suitable to support components for performing hemodialysis including a dialyzer (14), one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer. The housing may have a front panel (511) at which blood circuit connections and dialysate fluidic connections are located, e.g., blood line connections for patient blood access, connections for a reagent supply, dialyzer connections for both blood flow and dialysate, etc. The enclosure may also include a pair of vertical, side-by-side doors (53) hingedly mounted to the housing. With the doors in the closed position, access to the patient access and dialysate fluidic connections may be blocked, and the doors may allow for the retention of heat in the housing suitable for disinfection during a disinfection cycle.

Abstract: A distillation device may comprise a source fluid input and an evaporator in fluid communication therewith. The device may further comprise a compressor having an impeller coupled to a motor, the compressor having a low pressure inlet for vapor from the evaporator and a high pressure outlet for compressed vapor. The device may further comprise at least one temperature sensor configured to monitor temperature of vapor in the inlet and a condenser in heat transfer relationship with exterior surfaces of the evaporator and in fluid communication with the compressor outlet. The device may further comprise a controller configured to govern rotation speed of the impeller with an impeller motor command based on a calibrated motor speed for the distillation device. The controller may be configured to determine an adjusted motor speed for a next use of the device and overwrite the calibrated motor speed with the adjusted motor speed.

Abstract: A reagent supply connector system for hemodialysis apparatuses is provided. The system comprises: a water supply line coupled to and for providing water to a bicarbonate supply container; a bicarbonate supply line coupled to and for providing a bicarbonate solution from the bicarbonate supply container to the apparatus for producing dialysate solution; and an acid supply line to provide acid solution to the apparatus for producing the dialysate solution. The system further comprises an E-prong connector comprising three parallel prongs including two outer prongs in a common plane, and a center prong above the common plane: the first prong connected to the bicarbonate supply line; the second prong connected to the acid supply line; and the third prong connected to the water supply line. The three prongs allow connection to corresponding receiving holes of a connection point of the apparatus in a single orientation preventing improper connection.
