Claim Text:
1. An air mattress with an internal pump, comprising: a plurality of air cell groups lined up in a lengthwise direction of the air mattress, each of which groups is made from a plurality of bladder-shaped cells; an air supply/release pump provided with a power input cord and at least one signal cord; an air tube linking said air cell groups and said air supply/release pump in an independent system for each air cell group of two or more air cell groups out of said air cell groups for supplying or releasing air to and from said air cell groups; a first connector provided with air supply/release mouths connected to said air tube in said independent system for each air cell group; and a second connector provided with air supply/release mouths provided on and connected to said air supply/release pump in said independent system for each air cell group, said second connector being detachably connected to said first connector, wherein all of the bladder-shaped cells of said air cell groups are rod-shaped cells extending in a widthwise direction of the air mattress, and each of said air cell groups is configured so that the bladder-shaped cells are lined up in the lengthwise direction of the air mattress, wherein the bladder-shaped cells of the air cell groups other than the air cell groups corresponding to a heel area of a person lying on the air mattress extend to an edge of said air mattress, wherein the length of the bladder-shaped cells of the air cell groups corresponding to said heel area is up to 30% less than that of the other bladder-shaped cells, and a space is left between the cells and the edge of said air mattress, wherein said air supply/release pump is disposed in said space, and wherein, when the air supply/release mouths of the first connector are detached from the air supply/release mouths of the second connector, connections between said air tube in said independent system for each air cell group are released, thereby releasing control of a pressure within the bladder-shaped cells, and air within all of the bladder-shaped cells is released through said air tube.
