  • Patent number: 9737154
    Abstract: A method for adjusting pressure within an air bed comprises providing an air bed that includes an air chamber and a pump having a pump housing, selecting a desired pressure setpoint for the air chamber, calculating a pressure target, adjusting pressure within the air chamber until a pressure within the pump housing is substantially equal to the pressure target, determining an actual chamber pressure within the air chamber, and comparing the actual chamber pressure to the desired pressure setpoint to determine an adjustment factor error. The pressure target may be calculated based upon the desired pressure setpoint and a pressure adjustment factor. Furthermore, the pressure adjustment factor may be modified based upon the adjustment factor error determined by comparing the actual chamber pressure to the desired pressure setpoint.

  • Patent number: 9516921
    Abstract: The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second.

    Abstract: A plunger matrix mattress includes a number of independently movable foam padded plungers that form an array of independently movable points of support. This type of mattress significantly improves body contouring over conventional coil spring mattress designs. The plunger matrix mattress also allows substantial airflow through the mattress improving over conventional foam mattress designs. Different plungers may have different spring and dampening characteristics to allow different plungers and plunger zones of the mattress to exhibit different firmness levels. Individual plungers may be removed and replaced independently, for example to replace the plunger with another plunger with a different spring characteristic, and make other types of adjustments and repairs.

  • Patent number: 8914928
    Abstract: An alternating pressure pad (1) comprises inflatable cells (9,10) supplied with air by supply lines (7, 8) from a compressor (2) via supply line (3). A pressure controller controls the output of the compressor. Also connected to supply line (3) is an angle detection valve (40) restricting flow of air to atmosphere with increase in its angular position and a pressure transducer (17). Any increase in pressure due to an increase in angle of the detection valve (19) results in back pressure in the detection line. The pressure controller (2) uses the pressure transducer (17) to detect this change in pressure and then acts to adjust compressor output to the cells (9, 10) accordingly. The angle detection valve (40) is positioned under the head section of the pad to move with the head rest section.

The method and device may protect and individual from an injury resulting from landing in the enclosed container when the individual cushioning articles are overly compressed and lack appropriate spacing in order to absorb the kinetic energy of an individual landing in the enclosed container. The apparatus may include an air actuated inflatable bladder with inflatable extensions that may be utilized to lift and/or separate the cushioning articles, thus allowing the cushioning articles to be repositioned in a random, non-uniform, fashion.

  • Publication number: 20140208520
    Abstract: An air inflatable mattress and mattress coverlet are provided for the prevention and treatment of decubitus ulcers (i.e., pressure sores or bedsores). The mattress incorporates a user selectable static or alternating air powered support surface for more uniformly redistributing pressure exerted on a patient's skin. The mattress coverlet encompasses a low air loss feature independent of the mattress's user selectable air powered support surface. Such low air loss feature provides a patient contact surface exhibiting a high moisture vapor transfer ratio in conjunction with a forced air flow to aid in reducing the moisture and heat near the patient's body. Both the mattress and mattress coverlet are driven by an external control system which houses the user controls, as well as the necessary pumps, regulators, and valving.

  • Patent number: 8776798
    Abstract: Method and devices for the prevention and treatment of pressure ulcers are described in which a portable support assembly may be worn by a bed-stricken individual around particular regions of the body where pressure ulcers tend to form. The portable support assembly may generally include one or more individual fluid filled pods which are enclosed entirely within an inner fluid pad localized along a central portion. Both the one or more pods and inner fluid pad are then enclosed entirely by another layer of fluid within an outer fluid pad which extends over the entire assembly. Each of the fluid layers may be secured to an outer shell which is relatively stiffer than the fluid layers and may restrict or limit the expansion or movement of the fluid pods and/or fluid pads.

  • Patent number: 8756725
    Abstract: A patient support device. The support device includes a first side for contacting a surface, the first side having a perimeter portion and an inner portion. The support device further includes a second side for contacting a patient, the second side having a perimeter portion and an inner portion. The support devices also includes at least one baffle interconnected between the first and second sides. When in an unloaded state, the perimeter portion of the first side is in contact with the surface and the inner portion of the first side is spaced a first distance away from the surface. When in a loaded state the perimeter portion of the first side is in contact with the surface and the inner portion of the first side is spaced a second distance away from the surface. The second distance is less than the first distance.

  • Patent number: 8745784
    Abstract: There is described a mattress system (20) comprising a mattress, an airflow driving device (14) and a heat adjustment unit (28). The mattress has a mattress cover (24) enclosing an internal mattress (10) such that a mattress air chamber is formed between the internal mattress and the mattress cover. The airflow driving device is in fluid communication with the mattress air chamber via an air chamber inlet and an air chamber outlet. The airflow driving device is operable to drive an airflow through the mattress air chamber from the air chamber inlet to the air chamber outlet. The heat adjustment unit is for heating or cooling the airflow so as to control a temperature of the airflow within the mattress air chamber. There is also described a mattress. In addition, there is described an apparatus for providing a temperature-controlled airflow through a mattress air chamber connected to the apparatus.

  • Patent number: 8745796
    Abstract: A sensing device is configured for placing in an air cushion bed below air bladders thereof to detect an exact state of the bed in use, and includes a first and a second sheet connected together to define an air chamber therebetween. The air bladders and the air chamber are communicable with one another via inflation valves on the first sheet and are synchronously and identically inflated. First and second sensing elements are disposed outside and inside the air chamber, respectively. The first sensing element has deformation and acceleration sensors arranged thereon for monitoring how the bed reacts to a patient lying thereon and the manner in which the bed is being used. The second sensing element includes upper and lower conductive sensing sheets and an electrical connection state therebetween is used to detect whether the air bladders are sufficiently inflated. Thus, the air cushion bed is safer for use.
