Pneumatic mattress

摘要

A pneumatic mattress has two edge cells and transverse inner cells, arranged in adjacent pairs as alternate cells. An inflation hose has internal pipes, which receive alternating pneumatic pressure for the cells via extensions to connectors at both ends of cells. The edge cells are physically connected to the inner cells via the connectors.

主权项

1. A pneumatic mattress comprising:
an array of inner cells, pneumatic connectors pneumatically connected to at least corresponding ones of the inner cells and arranged along edges of the array of inner cells, longitudinal edge cells extending along edges of the array of inner cells and apertures spaced along the longitudinal edge cells through which the pneumatic connectors pass, whereby the pneumatic connectors physically connect to the edge cells to the inner cells, thereby providing a physical connection of the longitudinal edge cells at two sides of the mattress via intervening cells of the inner cells.
