1. A patient air mattress replacement system for use with a support bed frame comprising:
- an air source;
an air mattress replacement assembly for mounting on the bed frame and having a first air support layer and a second air support layer;
a controller assembly connected to the air source for selectively directing air to the first support layer and the second support layer;
a hose assembly system for connection to the air source for communicating air from the air source to the mattress assembly, the hose assembly having a first layer supply tube for providing air to the first layer and a second layer supply tube for providing air to the second layer;
an interface connection assembly connecting the mattress assembly to the hose assembly, the connection assembly communicating air from the first layer support tube to the first support layer and air from the second layer support tube to the second support layer, said connection assembly further having a first valve fitting for preventing escape of air through the interface connection assembly from the first air support layer when the hose assembly is disconnected from the interface connection assembly.

Abstract
A patient air mattress replacement system having a pair of air support layers with a hose assembly containing a plurality of supply tubes for providing air to the air support layers. The mattress includes an interface connection which connects the support layers to the hose assembly and valve fittings which prevent escape of air from at least one support layer when the hose assembly is disconnected from the interface connection.

8. A quick disconnect assembly for use with a patient air mattress replacement having a plurality of independently inflatable air chambers, said disconnect assembly connected between the air mattress and an air source, comprising,
a hose assembly system having an interface coupling assembly at one end of said hose system, a plurality of air supply tubes connected to the interface coupling assembly for providing air for the air chambers of the air mattress; -
an interface connection assembly connected to the air mattress and releasably connected to the interface coupling assembly, said connection assembly having an interface connection housing, having an inlet port; a plurality of tube fittings mounted within the housing; a plurality of distribution tubes, each tube having its first end connected to one of the internal chambers of the air mattress and its second end connected to the tube fittings within the housing; a plurality of resilient tabs mounted to the housing and extending circumferentially around the tube fittings and into the inlet port of the housing such that a clamping space is formed between the housing and the outer surfaces of the tabs, each tab having an internal raised ridge on its inner surface; the interface coupling assembly further having a coupling body, the body having a circumferential groove positioned so that the raised ridges of the resilient tabs mate with the groove when one end of the coupling body is partially inserted into the inlet port of the interface connection housing; and a spring biased release ring mounted to the coupling body adjacent the groove, the ring being resiliently positionable along the coupling body so that when the raised ridges of the resilient tabs are mated with the groove of the coupling body, the release ring may be positioned in the clapping space such that the release ring maintains the raised ridges of the resilient tabs in the groove of the coupling body whereby the coupling body is releasably connected to the interface connection body and air from the air supply tubes is directed through the tube fittings to the distribution tubes. - View Dependent Claims (9, 10, 11, 12)
