  • Patent number: 6282737
    Abstract: Method and apparatus for preventing bed sores in a bedridden patient. A low air loss bed is provided including a frame, a first set of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame, and a second set of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame, and all of the air bags are connected to a gas source. The conformation of the air bags is such that, when the first set of air bags is inflated, the patient supported thereon is moved toward the first side of the frame of the low air loss bed and, when the second set of air bags is inflated while the first set of ail bags is deflated, the patient is moved toward the second side of the low air loss bed. The conformation of the air bags also retains the patient on the top surface of the air bags when the patient is rolled in one direction or the other.

  • Patent number: 6163908
    Abstract: An air sac for use on a low air loss bed. The air sac is provided with a releasable connector for retaining the air sac to the low air loss bed and with a nipple for receiving air from a gas supply source to inflate the air sac. The air sac is also provided with a cutout which allows the patient to be rolled toward one end of the air sac when the air sac is inflated, A pillar is provided on the end of the air sac toward which the patient is rolled when the air sac is inflated to retain the patient on the air sac. The air sacs are arranged in sets with every other sac mounted to the frame of the low air loss bed in alternating arrangement whereby the patient is rolled first in one direction when the air sacs of one set are inflated and then back in the other direction when the air sacs in the first set are deflated and the air sacs in the second set are inflated.

  • Patent number: 6145143
    Abstract: A patient support system having multiple patient support layers for reducing and preventing the development of bed sores in bedridden patients. A top patient support surface is provided by an anti-shear cover layer. The anti-shear cover layer being operable to reduce lateral shear forces experienced by a patient moving across the patient support surface. One or more fluid pouches or bladders are provided to form a fluid bladder layer for reducing normal pressures and forces experienced by the patient. The fluid bladder layer being releasably or integrally secured to the top surface of an inflatable air mattress. Means are provided operable to secure the anti-shear cover layer and fluid bladder layer in overlapping relation to the inflatable air mattress. Also provided is a means for adjusting the temperature of the fluid contained within the fluid bladder layer.

  • Patent number: 5603133
    Abstract: Apparatus for preventing bed sores in a bedridden patient including a frame and first and second sets of substantially rectangular air bags for supporting a patient thereon mounted transversely on the frame, all of the air bags being connected to a gas source to maintain low interface pressures between a patient and the air bags to inhibit the formation and permit healing of bed sores caused by prolonged contact with hard surfaces. The conformation of the air bags is such that when the adjacent air bags are alternately inflated and deflated, the patient is rotated from side to side on the bed to therapeutically inhibit pulmonary problems and maintain low interface pressures between the patient and the air bags. The conformation of the air bags retains the patient thereon when rolled in each direction.

  • Patent number: 5044029
    Abstract: A method and apparatus for therapeutically treating immobile patients is disclosed. A low air loss bed is provided having groups of transversely oriented air bags, each group corresponding to a different portion of the body of a patent supported thereon. Each group comprises first and second sets of air bags alternately positioned in an interdigitated fashion. Valves and circuitry are provided for maintaining a selectable baseline pressure in the air bags belonging to each group.

  • Patent number: 5008965
    Abstract: A fluidized patient support apparatus is disclosed. The apparatus utilizes granular material beneath a patient support surface which when fluidized by pressurized gas uniformly distributes the pressure imparted to the body of a patient lying thereon. The apparatus includes means for recirculating the fluidizing gas in order to avoid raising the ambient temperature of a room in which the bed is situated with exhaust gas. Also provided are a pair of inflatable bladders and selective fluidization means to assist in turning and transferring the patient.

  • Patent number: 5005240
    Abstract: A low air loss bed having an integral source of air mounted to the frame thereof. Sets of air bags are mounted on the frame, each set of air bags corresponding to a portion of the body of the patient to be supported on the bed. Separate gas manifolds are provided, each of which connects a single set of air bags to the gas source. Individually controlled valves are used to adjust the amount of air which flows to the gas manifolds and on into the air bags. Also, means are provided operable to selectively route a flow of additional air to the gas manifold which supplies air to the air bags which support the heavier portions of the patient. A low air loss air bag is provided, as is apparatus for adjusting the amount of air supplied to each set of air bags and for controlling the temperature of the air delivered. Also provided is a means for simultaneously fully inflating all the air bags and means for simultaneously deflating all the air bags.
