Abstract

A lightweight, easy-to-assemble, and portable cart for the performance of peritoneal dialysis is disclosed. The cart includes a top shelf, bottom shelf, and at least four adjustable connecting members or legs. The top shelf has a top surface designed to receive a PD cycler, and at least one hook to hang bags of solution. Various components of the cart include a plastic and foaming agent additive.

Claims

1. A cart for facilitating peritoneal dialysis treatment, the cart comprising:

a top shelf component comprising

a top surface to support a peritoneal dialysis machine,

a plurality of cut-outs that extend inwardly from a side edge of the top shelf component, each cut-out being defined by first and second surfaces that extend inwardly from the side edge of the top shelf component and a third surface that joins the first surface to the second surface,

a hook extending from the first surface in a direction substantially perpendicular to the first surface within each of the cut-outs, each hook having a top surface that extends substantially parallel to the top surface of the top shelf component and that defines an upwardly facing concave depression to receive hanging bags of solution, and

a handle;

a bottom shelf component substantially parallel to the top shelf component, and

at least four connecting members, wherein each of the connecting members has one end connected to the top shelf component and an opposite end connected to the bottom shelf component, and wherein the connecting members are substantially parallel to one another, and wherein the top shelf component, the bottom shelf component, and the at least four connecting members comprise a plastic and a foaming agent additive.

2. The cart of claim 1, further comprising casters connected to the bottom shelf component.

3. The cart of claim 2, further comprising a locking or breaking mechanism configured to inhibit rotations of at least one of the casters.

4. The cart of claim 1, wherein the cart weighs less than 20 pounds.

5. The cart of claim 1, wherein the length of the connecting members is adjustable.

6. The cart of claim 1, wherein the plastic comprises polyphenylene oxide.

7. The cart of claim 1, wherein the plastic comprises one or more members selected from the group consisting of polyphenylene oxide, polystyrene, polycarbonate, and, acrylonitrile butadiene styrene.

8. The cart of claim 1, wherein the foaming agent additive comprises an approximately 20% active endothermic foaming agent concentrate.

9. The cart of claim 1, wherein the connecting members are releasably connected to the top shelf and the bottom shelf.

10. The cart of claim 1, wherein the cart is constructed to be assembled and disassembled without the use of tools.

12. The cart for facilitating peritoneal dialysis treatment of claim 1, wherein the top surface of the top shelf component defines a plurality of circular indentations arranged in a rectangular configuration, wherein each of the circular indentations is located in a region of the top shelf component that is centrally spaced from a peripheral edge region of the top shelf component in which each of the connecting members connects to the top shelf component.

11. A peritoneal dialysis system, comprising:

a peritoneal dialysis machine; and

a cart constructed to support the peritoneal dialysis machine, the cart comprising

a top shelf component comprising

a top surface to support,

a plurality of cut-outs that extend inwardly from a side edge of the top shelf component, each cut-out being defined by first and second surfaces that extend inwardly from the side edge of the top shelf component and a third surface that joins the first surface to the second surface, and

a hook extending from the first surface in a direction substantially perpendicular to the first surface within each of the cut-outs, each hook having a top surface that extends substantially parallel to the top surface of the top shelf component and that defines an upwardly facing concave depression configured to receive hanging bags of solution,

a bottom shelf component substantially parallel to the top shelf component; and

a plurality of connecting members that extend between the top shelf component and the bottom shelf component,

wherein the top shelf component, the bottom shelf component, and the connecting members comprise a plastic and a foaming agent additive.

13. The peritoneal dialysis system of claim 11, wherein the top surface of the top shelf component defines a plurality of circular indentations arranged in a rectangular configuration, wherein each of the circular indentations is located in a region of the top shelf component that is centrally spaced from a peripheral edge region of the top shelf component in which each of the connecting members connects to the top shelf component.

14. A peritoneal dialysis system, comprising:

a peritoneal dialysis machine; and

a cart constructed to support the peritoneal dialysis machine, the cart comprising

a top shelf component comprising

a top surface defining a plurality of circular indentations arranged in a rectangular configuration, and

at least one hook having a top surface defining a depression configured to receive hanging bags of solution,

a bottom shelf component substantially parallel to the top shelf component; and

a plurality of connecting members that extend between the top shelf component and the bottom shelf component, each of the connecting members being connected to a peripheral edge region of the top shelf component,

wherein each of the circular indentations defined by the top surface of the top shelf component is located in a region of the top shelf component that is centrally spaced from the peripheral edge region of the top shelf component, and wherein the top shelf component, the bottom shelf component, and the connecting members comprise a plastic and a foaming agent additive.

15. The peritoneal dialysis system of claim 14, wherein the indentations are configured to align with and receive protrusions extending from a bottom surface of the peritoneal dialysis machine when the peritoneal dialysis machine is positioned atop the cart.

16. The peritoneal dialysis system of claim 14, wherein the top surface of the top shelf component defines four circular indentations arranged in corners of a rectangle formed by the rectangular configuration, and the top surface of the top shelf component defines another circular indentation positioned in a center region of the rectangle.

17. The peritoneal dialysis system of claim 14, wherein the circular indentations are blind holes.

18. A cart for facilitating peritoneal dialysis treatment, in combination with a peritoneal dialysis machine, the cart comprising:

a top shelf component comprising

a top surface defining a plurality of circular indentations arranged in a rectangular configuration, and

at least one hook having a top surface defining a depression configured to receive hanging bags of solution,

a bottom shelf component substantially parallel to the top shelf component; and

a plurality of connecting members that extend between the top shelf component and the bottom shelf component, each of the connecting members being connected to a peripheral edge region of the top shelf component,

wherein each of the circular indentations defined by the top surface of the top shelf component is located in a region of the top shelf component that is centrally spaced from the peripheral edge region of the top shelf component, wherein the circular indentations are configured to align with and receive protrusions extending from a bottom surface of the peritoneal dialysis machine when the peritoneal dialysis machine is positioned atop the cart, and wherein the top shelf component, the bottom shelf component, and the connecting members comprise a plastic and a foaming agent additive.
