A mattress-integral stone bed is disclosed. The constitution of the mattress-integral stone bed is simplified by eliminating the conventional supporting frame unit so as to curtail the manufacturing cost and so as to improve the economy. Further, its handling is rendered convenient owing to the simplified constitution, as well as making the moving of the stone bed easy when moving the residence. Further, the internal stacked elements of the mattress such as stone plate, supporting plate, electro-heating plate and fixed plate are secured in a form of a sealed firm structure, so that the stacked elements can be prevented from being detached, thereby protecting the stacked elements from damages when moving. The mattress-integral stone bed according to the present invention includes the following elements. That is, rectangularly bent engaging pieces are fastened with fastening means on an inside of an installation opening of the mattress body. A securing plate is coupled to a bottom of the mattress body with fastening means. A rectangular supporting frame is provided with a plurality of detachably assembling holes, the detachably assembling holes reaching the securing plate. A plurality of supporting legs are respectively fitted into the plurality of the detachably assembling holes.
A therapeutic mattress assembly comprising a mattress having a substrate assembly that includes a plurality of cylinders positioned side by side over the length of the mattress. Each cylinder is configured as a low air loss system to allow air to flow into the cylinder from a source and out of the cylinder through small holes located on the top of each cylinder. An overlay assembly provides a foam cushion that provides a supporting surface above the substrate assembly for the patient. A calf lift bladder operates to effectively raise or lower the patient's feet to prevent pressure related injuries. A lateral rotation assembly selectively raises and lowers a selected half of the mattress to turn patients in a lateral direction. A bolster inflates in response to the lateral rotation assembly to secure the patient within the mattress.
Abstract
A mattress comprises a sealed outer casing within which is mounted a resilient support formed by a composite foam core. At least an upper portion of the resilient support is formed by a visco-elastic foam. A vent is provided in a side wall of the casing and is covered by a filter which prevents ingress of bacteria into the cover. A flap is mounted on the cover and in use extends down over the vent to prevent the filter being damaged by fluids.
The present invention relates to a mattress (10), for use as a bed, which mattress comprises substantially resilient material such as a foam rubber, spring devices (4) such as coil springs being provided in the mattress, in order to distribute the pressure exerted upon the mattress. The mattress according to the invention is characterised in that the mattress comprises at least two layers (1,2) placed one on top of the other, blind holes (3) for the accommodation of the spring devices (4) being made in at least one of said two layers, which blind holes connect to the boundary face between the two layers. |
