Abstract: Apparatus and methods for adjusting a support to a body are described in which a portable support assembly may be worn or used by a bed-stricken or wheel-chair restricted individual around particular regions of the body where pressure ulcers tend to form. The portable support assembly may generally include adjustable supports which conform the assembly to the patient's body and which also help to distribute one or more fluid pad assemblies relative to the body. The support assembly may be incorporated into a design for a wheelchair or a bed.

Abstract: Embodiments include a person support apparatus including a plurality of air fluidizable material, a tub, a foam bolster disposed along at least one wall of the tub and extending over the at least one wall, and an inflatable air bladder disposed above the foam bolster along the at least one wall of the tub. A method of assisting a person with ingress or egress of a person support apparatus by deflating the inflatable air bladder and adjusting a level of fluidization of the air fluidizable material such that the surface supporting the portion of the person is substantially level with a top of the foam bolster is also described.

Abstract: A constant low-flow air source control system and method is used to operate a pump to inflate an inflatable support structure used to support a person.

Abstract: A pad assembly includes an air-filled base having an air-filled first bladder and an air-filled second bladder connected to a top of the base. A first liquid-filled part is rested in a recessed area in the first bladder and a second liquid-filled part is rested in a recessed area in the second bladder. The first part and the second part respectively support a user's body and hip. The base is supported on a frame and a swinging exerciser is put on the frame so that the user lies on the bladders and the feet is rested on the swinging exerciser.

Abstract: A water bed structure includes water containing bodies, a concave bed body, air protection borders and a bed housing, wherein the water containing bodies are installed in accommodating chambers formed by the concave bed body and the air protection borders, and are placed into the bed housing. The concave bed body has each of four sides thereof provided with at least two openings for installing four unfilled air protection borders through the openings. The four air protection borders are provided with air inlet plugs that are located at the openings at the four sides of the four air protection borders. The assembled air protection borders and the concave bed of the water containing beds are placed into an inverted U-shape bed housing in an upward direction, such that the openings of the concave bed body and the air inlet plugs of the air protection borders are concealed.

Abstract: A mattress device includes a plurality of dual-fluid fluidizing units juxtapositionally secured in a mattress envelope; each dual-fluid fluidizing unit consisting of a lower air cell and an upper gel (or gel-like) cell superimposed and secured on the lower air cell, having a plurality of flexible ventilating and baffling tubes formed through each upper gel cell for venting air from the lower air cell to the patient's body as lying on the upper gel cells for therapeutically treating the patient as synergetically effected by both the air and gel cells.

Abstract: An improved waterbed having a waterbed mattress and a bed protecting cover with airbag protecting sides. The waterbed mattress has a plurality of internal, transverse partitions welded by high-frequency heat sealing, arranged at intervals in single or double rows, with water openings. When the water is filled and the air is inflated, the partitions buffer the water forces to increase the stability and maintain the bed mattress firm, straight and in shape. The level of compressing force towards the waterbed mattress can be changed by increasing or decreasing the air pressure in the airbag protecting sides to adjust the softness and hardness of the waterbed mattress.

Abstract: A portable water cooled mattress for use with infants or the like comprising an air bladder lower level constructed of an air proof material and including an inflation and deflation opening valve. A water bladder layer is positioned on a top surface of the air bladder and includes a fill and empty spout valve while a pocket is formed between the water bladder and air bladder suitable for inserting either heating and/or cooling packs as desired. An insulating upper layer covers the water bladder preventing the child from becoming dampened from condensation.

Abstract: A constant-pressure waterbed is provided, which can provide a constant air pressure to a sole air-pressure frame that surrounds a water-filled mattress so as to allow the water in the water-filled mattress to be always suitably compressed to provide the desired level of softness. The air-pressure frame is used to apply an air pressure of a preselected limit level to the water-filled mattress. The constant-pressure waterbed utilizes a drainage valve to drain excessive air in the event that the air pressure in the air-pressure frame is above a preselected limit level so as to maintain the air pressure at the preselected limit level. Moreover, the constant-pressure waterbed utilizes an air pump which can pump air into the air-pressure frame when the air pressure in the air-pressure frame is below the preselected limit level. The air pressure in the air-pressure frame can therefore always be maintained at the desired level so as to allow the water-filled mattress to always provide the desired level of softness.

Abstract: An improvement for a water bed includes a pair of water bed mattresses housed in a bed cover. There is a heat insulating foam or air bag sandwiched between the two water bed mattresses. Each water bed mattress has a plurality of transverse partitions to reduce water vibration and turbulence therein. The disclosed structure has the advantage of not only improving the stability, but also lengthening the durability of the water bed mattress. A plurality of longitudinal air tubes run through the transverse partitions and communicate with an air bag for providing a desired softness of the water bed mattresses to suit an individual user's requirements. Moreover, the disclosed water bed mattress is able to support a user's back bone comfortably, and minimize the quantity of water used for the mattress to reduce its weight.

Abstract: A water bed in accordance with the present invention comprises a water bed base and a plurality of water bed mattresses. The water bed base defines a number of container chambers into which an equivalent number of water bed mattresses are respectively removably inserted. Each container chamber is sealed and thus advantageously prevents any of the water bed mattresses which may be leaking water from leaking water outside of the water bed base. Further, the leaking water bed mattress, because it is removably inserted into the water bed base, may be individually replaced. Also, the water bed mattress has a plurality of air and water chambers, some having fluid baffles to restrict the free flow of fluids. Further, the water bed base has several air chambers. These chambers maintain the shape of the water bed while providing a regulator and an absorbing means of the pressure inside the water bed. Thus, user comfort is maximized.
