An incontinence bed pad comprised of one or more inflatable pads and one or more absorbent pads for use under a patient on a bed. The inflatable incontinence bed pad serves to spread pressure over an increased area for the patient to prevent or treat bed wounds. The inflatable pad may channel or drain fluids such as urine into the absorbent pad below, keeping the surface and patient dry. Alternately, the absorbent pad may be placed above the inflatable pad to reduce cleaning work. The one or more air bladders are inflatable through one or more ports. The ports pass air from one or more manual or powered air pumps to the one or more air bladders. Making an incontinence pad of an inflatable nature offers advantages not available in the prior art. The inflation and deflation of distinct sealed chambers or zones within the inflatable pad may tilt a patient's hips to the right and to the left periodically. The pad may inflate in a static position. The pad may inflate and deflate zoned areas to alternate pressure areas of the patient. Inflating and deflating areas of the pad may push waste away from the person. The inflated pad may leak air to wick moisture and heat from a patient. Handles may be integrated to the inflatable incontinence bed pad for transferring the patient on and off the bed and to other places. Straps compatible with a patient lift system may be integrated. This could reduce work and injury to care providers, as well as reducing disruption to the patient. Side rails may be integrated for safety.

An external suspension system for supporting an inflatable air duct includes a series of external hangers that help hold the duct open while the duct is deflated. In some embodiments, the suspension system supports the duct at a series of points that are broadly distributed in a staggered pattern across the duct, yet the entire duct can be suspended from a single overhead cable, even if the duct is a stepped tube with multiple diameters. The system includes novel ways of locking the hangers to the duct and to the overhead cable.

The Automatic Patient Turner is the ultimate in pressure sore prevention by automatically, periodically, and alternately tilting, and then laterally turning an immobile patient from one complete side to the other in a manner similar to, yet gentler and less intrusive than, manual turning. This is accomplished by the patterned, sequential inflation and deflation of six strategically-placed inflatables. When the bent knees (1) are perpendicular and sandwiched between a pair of inflated knee inflatables (6 and 7), they can serve as a lever arm in the turning process. When pressure is exerted against the bent knees (1), it causes them to move well beyond their perpendicular position. They then descend in the direction of the turn as the knee inflatables (6 and 7) deflate. The descending knees laterally pull the entire body of the patient completely to the side of the turn as a back-support pillow (8 or 9) inflates.
