Abstract

A patient support includes a conformable layer having a lattice of cells. Each cell having a base and extending to a top portion disposed opposite the base to form a column, and at least some of the cells within the lattice having a fluid passage extending from the base through the top portion of the cell. The patient support having a fluid flow path defined by a port connector configured to direct a fluid to a low air loss manifold, the low air loss manifold configured to direct and release the fluid towards the fluid passages of the conformable layer with the fluid passages configured to direct the fluid into a reduced zone having a surface area, and a spacer layer configured to receive the fluid in the reduced zone and disperse the fluid underneath a cover across a surface area larger than the surface area of the reduced zone.

Dependent claims

A patient support for supporting a patient, the patient support comprising:

a conformable layer including a lattice of cells each having a base and extending to a top portion disposed opposite the base to form a column, with at least some cells within the lattice having a fluid passage extending from the base through the top portion of the cell, wherein the top portion of the lattice of cells defines a patient support surface area spanning the lattice of cells, and wherein the fluid passages of the cells of the conformable layer define an air volume and further define a material volume at least partially surrounding the air volume with the air volume being larger than the material volume;
a spacer layer disposed above the conformable layer spanning the patient support surface area;
a cover assembly enclosing the conformable layer and the spacer layer;
and
a fluid source to direct fluid along a fluid flow path towards the fluid passages of the conformable layer, the fluid passages configured to direct the fluid into a reduced zone having a surface area, and the spacer layer configured to receive the fluid in the reduced zone and disperse the fluid underneath a top surface of the cover assembly across a surface area larger than the surface area of the reduced zone.
