Patient support surfaces

A patient support surface configuration providing for modular completion and usage of alternative constructed combinations constituting a line of related products, comprising:

• a main chassis defined by a perimeter bolster;
• supplemental inner bolsters provided within an inside perimeter defined by said perimeter bolster;
• a plurality of elongated air cylinders received within said perimeter bolster inside perimeter and within said supplemental inner bolsters;
• a body of resilient foam, defining an upper support surface, and covering said air cylinders, said resilient foam body redistributing pressure among said air cylinders while cooperating with said supplemental inner bolsters for maintaining each of said air cylinders in a respective position while said main chassis provides basic structural integrity for said patient support surface;
• and
• a cover surrounding said main chassis, said inner bolsters, said air cylinders and said body of resilient foam.

A rechargeable static air mattress system, comprising:

• a plurality of air cylinders;
• a foam chassis receiving and surrounding said air cylinders;
• a cover surrounding said chassis and said air cylinders;
• an air valve positioned for access thereto while said cover surrounds said chassis and said air cylinders;
• air tubing connecting at least one of said air cylinders with said air valve, such that air pressure via said air valve may be selectively bled off from such at least one air cylinder and alternatively introduced thereto for recharging such at least one air cylinder to a predetermined unloaded air pressure rating;
• and
• wherein said air valve comprises a normal closed air valve defining an aperture for receipt of a needle valve member for opening such normally closed air valve.

A patient support surface with a perimeter safety feature, comprising:

• a foam perimeter bolster having a first predetermined density;
• supplemental inner bolsters received inside of said perimeter bolster and having a second predetermined density;
• a plurality of air cylinders received within said inner bolsters;
• and
• a covering surrounding said perimeter and inner bolsters and said air cylinders;
• wherein said perimeter bolster guides a patient supported on said air cylinders away from the perimeter of said support surface for improved safety of such patient.

A patient support surface with improved structural stability, comprising:

• a plurality of air cylinders situated in a predetermined grouping;
• a foam topper having an upperside forming a patient support region and having an underside with corresponding interlocking members for receipt on top of said air cylinders for engaging and capturing said air cylinders, for improved patient support surface integrity and performance;
• wherein at least some of said air cylinders are generally longitudinally positioned along said patient support surface;
• and
• said patient support surface further includes a pair of foam inner bolsters respectively disposed along adjacent lateral sides of said patient support surface with said air cylinders received therebetween.

A modular patient support assembly, comprising:

• plural patient support air cylinders;
• a resilient foam perimeter surrounding said air cylinders;
• an upper foam topper covering said air cylinders and including underside multiple curved projections interoperative with said air cylinders for positional stabilizing;
• and
• a surrounding cover;
• wherein said foam topper includes a lower leg and foot supporting area having decreasing angled support in such area, for improved pressure reduction to a patient's lower legs and feet.
