Manifold Diaphragms
First Claim
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.

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.

7. 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. a first substantially planar surface having a first end and a first bend wherein a distance between the first end and first bend defines a length and a height of said first planar surface, wherein said first end is fixedly attached to said manifold, further wherein said height of said first planar surface is substantially equal to the height of said manifold; b. a convex exterior surface continuing and protruding outward from said first bend of said first planar surface, said convex exterior surface continuing from said first bend to a second bend, wherein a distance between the first bend and second bend defines a length and height of said convex surface, wherein the convex surface at the first bend and the second bend has the same height as the first planar surface, wherein the height of said convex exterior surface increases from said first bend to a second height relative to the manifold, and wherein the height of said convex exterior surface decreases from said second height to the second bend; and
,c. a second substantially planar surface, continuing from said second bend to a second end, wherein a distance between the second bend and second end defines a length and a height of said second planar surface, wherein said second end is fixedly attached to said manifold, further wherein said height of said second planar surface is substantially equal to said height of said first planar surface and said length of said second planar surface is substantially equal to said length of said first planar surface. - View Dependent Claims (8, 9, 10, 11, 12)

14. 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. a first sloped surface having a first end and a first bend wherein a distance between the first end and first bend defines a length of said first sloped surface, wherein said first end is fixedly attached to said manifold, further wherein said first sloped surface has a first height at said first end and a second height at said first bend, wherein said second height of said first sloped surface is greater than said first height of said first sloped surface relative to said manifold, further wherein said first height of said first sloped surface is substantially equal to the height of said manifold; b. a convex exterior surface continuing and protruding outward from said first bend of said first sloped surface, said convex exterior surface continuing from said first bend to a second bend, wherein a distance between the first bend and second bend defines a length and height of said convex surface, wherein the height of the convex surface at the first bend and the second bend is the same as the second height of the first sloped surface, wherein the height of said convex exterior surface increases from said first bend to a second height of said convex surface relative to the second height of said first sloped surface, and wherein the height of said convex exterior surface decreases from said second height of said convex surface to the second bend; and
,c. a second sloped surface, continuing from said second bend to a second end, wherein a distance between the second bend and second end defines a length of said second sloped surface, wherein said second end is fixedly attached to said manifold, further wherein said second sloped surface has a first height at said second bend and a second height at said second end, wherein said first height of said second sloped surface is greater than said second height of said second sloped surface relative to said manifold, further wherein said second height of said second sloped surface is substantially equal to said first height of said first sloped surface, said first height of said second sloped surface is substantially equal to said second height of said first sloped surface, and said length of said second sloped surface is substantially equal to said length of said first sloped surface. - View Dependent Claims (15, 16, 17, 18, 19, 20)
