Manifold diaphragms
First Claim
1. A dialysis system comprising:
- a dialysis machine having a controller, sensor component, a reservoir and a dialyzer;
a disposable monolithic manifold in fluid communication with the reservoir and dialyzer, wherein the disposable monolithic manifold has a diaphragm integrated therein and is adapted for installation in the dialysis machine, wherein the diaphragm is adapted to be compressed by the sensor component located within the dialysis machine and external to the disposable manifold, and wherein the diaphragm comprises;
a convex exterior surface protruding outward from the manifold and fixedly attached to the 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 the diaphragm, wherein the diaphragm at the first end and second end has the same height as the manifold, wherein the height of the convex exterior surface increases from the first end to a first height relative to the manifold, and wherein the height of the convex exterior surface decreases from the first height to the second end.

Abstract
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.
