Abstract

An enclosure for containing a portable hemodialysis unit includes a housing suitable to support components for performing hemodialysis including 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 may have a front panel 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 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.

Claims

1. An enclosure for a portable hemodialysis apparatus comprising:

a housing having a holder or hook configured to be retractable into a recess in the housing when not in use and a front panel comprising a dialyzer and one or more blood pumps, the front panel enclosable by a pair of vertical side-by-side doors hingedly mounted to the housing at opposite sides of the front panel, the doors being movable between open and closed positions, the open position allowing access to connections and mounting sites for the dialyzer and the one or more blood pumps;

the front panel separating the dialyzer and the one or more blood pumps from a dialysate section and a control section, the dialysate section including one or more dialysate pumps for connection to the dialyzer, and the control section comprising a controller configured to control the one or more blood pumps and the one or more dialysate pumps and to communicate with one or more user interfaces;

wherein a first user interface of said one or more user interfaces is a graphical user interface configured for connection to the controller so that said first user interface can be hung on the housing by the holder or hook, and placed on a surface away from the housing.

2. The enclosure of claim 1, comprising a second user interface of said one or more user interfaces, said second user interface located on the front panel and enclosable by the doors.

3. The enclosure of claim 2, wherein the second user interface comprises one or more buttons permitting a user to override or bypass one or more commands that the first user interface is configured to receive from the user.

4. The enclosure of claim 3, wherein said one or more commands includes a stop command, a pause command, or a command to infuse dialysate into a blood circuit comprising the one or more blood pumps and the dialyzer.

5. The enclosure of claim 1, wherein the first user interface is configured for connection to the controller by means of a cable connected to the housing.

6. The enclosure of claim 1, wherein the first user interface and the housing are configured for placement of the first user interface on a top surface of the housing.
