Support for a premature infant

Claim 2

A support for a premature infant comprising means defining a stationary convex surface of such dimensions as to accommodate the leg structure of an infant, means defining a relatively flat mobile surface dimensioned to accommodate the back structure of an infant, vertically spaced supports comprising spaced, parallel side wall panels to which said means defining the stationary surface is fixed, and a hinge for positioning the mobile surface at several predetermined angular positions relative to the stationary surface, said hinge comprising horizontal slots in the side wall panels and pin means at the proximal ends of the flat mobile surface engaged with the slots, said slots being dimensioned to permit rotation of the pin means and movement of the pin means along the slots and wherein the crest of the convex stationary surface occurs at approximately the location of the knee joints.

Claim 3

A support according to claim 1 wherein the slope of the convex portion at the proximal side rising to the crest is less than the slope of the convex portion of the distal side descending from the crest.

Claim 4

A support according to claim 1 wherein the slope of the convex portion rising at the proximal side to the crest is approximately 30° to 45° and the slope of the convex portion at the distal side descending from the crest is approximately 40° to 65°.

Claim 5

A support according to claim 1 wherein the crest is located approximately 5/8 of the way from the lower edge of the proximal side to the lower edge of the distal side.

Claim 6

A support according to claim 1 wherein the lower edge of the mobile surface meets the lower edge of the stationary surface and the mobile surface is angularly movable at the meeting edges about a horizontal axis parallelling said edges.

Claim 7

A support according to claim 1 wherein the lower edge portions of the mobile and stationary surfaces are slightly concave so as to merge smoothly.

Claim 8

Apparatus according to claim 2 wherein the structure is comprised of a synthetic resin material.

Claim 9

A support for a human form comprising a stationary bottom supporting surface for accommodation of the legs and a mobile back-supporting surface for accommodating the back, means supporting the stationary and mobile surfaces with an edge of the mobile back-supporting surface adjacent an edge of the stationary bottom supporting surface, said means comprising spaced, parallel side wall panels coextensive in length with the stationary and mobile supporting surfaces, said stationary bottom supporting surface being fixed at its opposite edges to the respective side wall panels, hinge means connecting the end of the mobile back supporting surface adjacent the stationary bottom surface for angular movement relative to the stationary bottom supporting surface between the side wall panels to enable raising or lowering the back supporting surface, means at the distal end of the back supporting surface engageable with means on the side wall panels to support the back supporting surface at a selected angle, and a flexible pad positioned on the back and leg supporting surfaces, said side wall panels containing slots at the junction of the leg supporting surface with the back supporting surface and a strap threaded through the slots transversely of the structure for holding the flexible pad in position.

Claim 10

A support for a human form comprising a stationary bottom supporting surface for accommodation of the legs and a mobile back-supporting surface for accommodating the back, means supporting the stationary and mobile surfaces with an edge of the mobile back-supporting surface adjacent an edge of the stationary bottom supporting surface, said means comprising spaced, parallel side wall panels coextensive in length with the stationary and mobile supporting surfaces, said stationary bottom supporting surface being fixed at its opposite edges to the respective side wall panels, hinge means connecting the end of the mobile back supporting surface adjacent the stationary bottom surface for angular movement relative to the stationary bottom supporting surface between the side wall panels to enable raising or lowering the back supporting surface, means at the distal end of the back supporting surface engageable with means on the side wall panels to support the back supporting surface at a selected angle, and a flexible pad positioned on the back and leg supporting surfaces, said side wall panels containing slots at the junction of the leg supporting surface with the back supporting surface and a strap threaded through the slots transversely of the structure for holding the flexible pad in position.
