Manifold Diaphragms

摘要

The specification discloses a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The manifold includes diaphragms adapted to minimize the dead space between the dialysis machine pins and improve responsivity. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface and a heater in thermal communication with the container. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

1. A diaphragm integrated into a disposable manifold for use in a dialysis machine and adapted to be compressed by components that are within said dialysis machine and external to said disposable manifold, said diaphragm comprising: a convex exterior surface protruding outward from the manifold and fixedly attached to said manifold at a first end and at a second end, wherein a distance between the first end and second end defines a length and height of said diaphragm, wherein the diaphragm at the first end and second end has the same height as the manifold, wherein the height of said convex exterior surface increases from said first end to a first height relative to the manifold, and wherein the height of said convex exterior surface decreases from said first height to the second end.
