Air mattress turning device

A pump and valve assembly, comprising:

• comprising a first fluid valve, a second fluid valve, and a third fluid valve, wherein said each of said first, second and third fluid valves are enclosed within a housing and are further defined as a diverter valves having a first port, a second port, and a third port;
• each fluid valve having a first state, second state and a third state;
• and wherein each of said at least one valves is individually controllable to a either said first state, said second state, or said third state;
• and wherein, for each valve:
• said first state allows fluid communication between said valve first port and said valve third port, allowing a fluid to pass between said first port and said third port, and there is no fluid communication between said second port and said third port;
• and
• said second state allows fluid communication between said valve second port and said third port, allowing a fluid to pass between said second port and said third port, and there is no fluid communication between said first port and said third port;
• and
• said third state does not allow communication between any of the first, second or third valve ports;
• and wherein each of said fluid valve first ports are in fluid communication with one another through a first plenum formed by a first enclosed volume within said housing;
• all of said valve third ports are in fluid communication through a through a second plenum formed by a second enclosed volume within said housing;
• said second port of said first valve is in fluid communication with said first set of bladders;
• said second port of said third valve is in fluid communication with said second set of bladders;
• and
• said second port of said second valve is in fluid communication with an environment external to said housing.

A method for rotating a person to prevent bed sores, comprising the steps of:

• providing a first set of bladders comprising at least one inflatable bladder;
• providing a second set of bladders comprising at least one inflatable bladder;
• wherein said first set of bladders is disposed adjacent to said second set of bladders placing a person in a supine position on said first set of bladders and said second set of bladders so that a portion of the person's body is disposed on said first set of bladders, and a portion of the person's body disposed upon said second set of bladders, when each of said first and second set of bladders are deflated in a flat position;
• and
• rotating said person into a first position by inflating said first set of bladders with a fluid while said second set of bladders is deflated, causing the person to be rotated into a first position;
• rotating said person into a second position by inflating said second set of bladders with a fluid while said first set of bladders is deflated, causing the person to be rotated into a first position;
• and
• rotating said person into a supine position by causing fluid to be removed from both of said first set of bladders and said second set of bladders, causing both of said first set of bladders and said second set of bladders to be in a flat position.
