ABSTRACT:
A mattress wherein at least one fabric strip bridges a foam crib for an inflatable cushion to provide lateral stability thereto such as when the mattress is tilted for turning a patient over or otherwise. The fabric strip position is selected so as not to interfere with pressure relief to a portion of the patient's body where pressure ulcers frequently occur. In order to accurately and quickly monitor the tilt of a mattress, transmitting and receiving coils are provided on opposite sides of an assembly of lifting bladders for the side of the mattress being lifted, and the signal strength is measured when a signal is transmitted therebetween, and the angle of tilt is determined therefrom. In order to reduce exposure of lines leading to an inflatable mattress, a notch is provided in a crib for receiving a pump for pressurizing a cushion within the crib so that the pump is positioned to face exteriorly of the crib to allow heat dissipation. In order to extend the life of a cubed foam mattress, the mattress comprises at least two identical interchangeable cubed foam sections. In order to effectively provide pressure relief to a person lying on a mattress while preventing bottoming-out when a person sits on the mattress, the mattress is provided with an upper alternating pressure cushion and a lower cushion which allows the pressure in the upper cushion to be reduced and which is of a non-alternating pressure type. Side-by-side bladders are provided between upper and lower side-by-side cushions respectively for inclining the mattress. Hip bladders are provided to apply pressure to the hip area of a person lying on the mattress on a side opposite to the side of the mattress being inclined in order to maintain body alignment.
