Abstract
A low air loss mattress 20 made of multiple cushions 21, 22 and 23 which are connected together and which form an integral mattress which may be used on a standard hospital bed. Each section 21, 22, and 23 is formed by sewing together upper and lower sheets 27 and 28, 29 and 30, and 31 and 32, which sheets are also connected by multiple retaining means 50 which act as air vent means to allow air to escape in the area where a patient lies to provide comfort to the patient and to allow pressure regulation in each of the cushions.

7. A low air loss therapeutic patient support mattress comprising:
-
a plurality of adjacent air cushions formed of upper and lower connected sheets forming a low air loss patient support mattress when inflated; each of said cushions having plural retainers positioned in spaced relation on the patient support surface; said retainers having stitching holes forming means for allowing air to escape from at least the upper surface of each cushion to provide comfort and therapy to a patient on the inflated mattress and regulation of the air pressure in each cushion to maintain low interface pressures; and said retainers maintaining the upper and lower sheets of each cushion in limited spaced relationship to provide a generally flat patient support surface. - View Dependent Claims (8, 9, 10, 11, 12)

13. A low air loss therapeutic patient support mattress overlay comprising:
-
a low air loss patient support mattress having a plurality of adjacent inflatable cushions formed of upper and lower connected sheets; the upper sheets of each of said cushions having perforations formed therein for venting air from within the cushions unto a patient supported thereon; each of said cushions having plural retainers positioned in spaced relation on the patient support surface, maintaining the upper and lower sheets of each cushion in limited spaced relationship to provide a generally level patient support surface; said retainers comprising stitching threaded through said perforations in a manner such that air is able to escape through said perforations to provide comfort and therapy to a patient supported on the inflated cushions. - View Dependent Claims (14)

15. A low air loss therapeutic patient support mattress overlay comprising:
-
a low air loss patient support mattress having a plurality of adjacent inflatable cushions formed of upper and lower connected sheets; the upper sheets of each of said cushions having perforations formed therein for venting air from within the cushions unto a patient supported thereon; said perforations being formed by retainers which provide recesses in the upper sheets of said cushions which, due to their recessed nature, tend to be separated from direct contact with a patient supported on said cushions.
