  • Patent number: 11083305
    Abstract: Embodiments of the invention provide a method of mounting an inflatable headboard assembly to a horizontal plane (e.g., a bed) without using a fixed mechanical fastening. The headboard assembly may assume various shapes, sizes, and/or styles while affording easy assembly and storage. The inflatable headboard assembly does not require permanent modification to its surrounding area. Rather, the inflatable headboard assembly is simply inflated to various heights that conform to the existing dimensions of the surrounding environment. The inflatable headboard assembly can be mounted to various locations of a bed without requiring additional equipment, and deflated for compact storage. The inflatable headboard assembly may include an inflatable footboard counterpart similar to the inflatable headboard assembly but smaller in scale. In addition, the inflatable headboard assembly may include lights for illuminating portions of the headboard, and/or visual markers for receiving augmented reality overlay.

    Abstract: An inflatable structure has an air mattress capable of sustaining an air pressure, and having a mattress aperture through a side wall of the air mattress. The inflatable structure further includes a panel secured with fasteners for fastening the first pair of opposing edges to the air mattress such that a panel aperture is positioned over the mattress aperture. Finally, the inflatable structure includes an elongate sheet having a sheet aperture. The elongate sheet is slidably mounted between the panel and the air mattress so that the elongate sheet may slide between a closed position wherein the elongate sheet covers the mattress aperture to provide a seal over the air mattress, and an open position wherein the sheet aperture is aligned with the mattress aperture and the panel aperture, thereby permitting air/water to drain out of the air mattress.

  • Patent number: 10729255
    Abstract: A data processing system is configured to sense a pressure readings of an air-mattress. If the pressure readings are below a target pressure value representing a desired pressure for the air-mattress, the data processing system can transmit, to an air-pump, first instructions to increase the air pressure of the air mattress and determine a replacement value representing the amount of air pumped into the air mattress by the air-pump. The data processing system can compare the replacement value to a slow-leak threshold and to a catastrophic-leak threshold. The data processing system can, responsive to a determination that the replacement value is greater than the slow-leak value and less than the catastrophic-leak value, transmit, to the air-pump, second instructions to increase the air pressure of the air mattress to replace air in the air mattress lost to a slow leak so as to maintain the desired pressure for the air-mattress.

  • Patent number: 10653573
    Abstract: A high-performance, low-cost modular cushion using range of novel dynamically responsive materials has been designed and developed for use in seating pressure relief. The use of individual contained spheres creates a localized area of gel to minimize both flattening under pressure, and inflating in areas without contact while the elastic nature of the polymers creates a durable system that recovers rapidly from deformation. Gel balls of varying densities have been developed to optimize performance. Quantification of individual ball mechanical properties has been completed which provides load-deflection curves to inform optimal ball array layout based on user interface pressure distributions. A fitting algorithm is proposed which will employ the patient's seating interface pressure distribution to design a personalized modular cushion layout which will evenly distribute contact pressure across seating support interface and maximize contact pressure area.

  • 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.

  • Publication number: 20140345060
    Abstract: A sleep apparatus, such as a mattress for example, is provided in one embodiment. The apparatus comprises a head support surface sized to support a person's head, and a torso support surface sized to support a person's torso. The head support surface is generally laterally sloped moving from the first side toward the second side, and the torso support surface is generally laterally sloped moving from the first side toward the second side. In some embodiments, the lateral slope of the head support surface is at least about 15°, the lateral slope of the head support surface is greater than the lateral slope of the torso support surface, and/or, the sleep apparatus slopes in the longitudinal direction as well.

  • Patent number: 8887732
    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.

  • Publication number: 20140317855
    Abstract: This invention relates to a pressure relieving mattress including an elongate support 11 having a base 12, a pressure relieving overlay 15 and an inflatable inlay 16. The inlay 16 has a plurality of laterally extending inflatable cells 23. At least some of the cells, in at least their un-inflated state, have an inflatable volume which is wider adjacent its ends than its mid portion. This reduces the likelihood of gaps appearing between the pressure overlay and the walls of the tray.

  • Publication number: 20140317854
    Abstract: The present invention describes an inflatable device, illustrated as an inflatable bed, which is designed to minimize damage to the bed as a result of under or over inflation. The inflatable bed comprises an inflatable mattress which includes an inflation indicator. The inflatable mattress includes a pop-up valve indicator assembly comprising an indicator pin, a compressible and extendable member such as a spring, and a barrier member such as diaphragm, all housed within the interior of the inflation indicator. The indicator pin further contains indicia to provide visualization as to the amount of air inflated within the inflatable mattress. The indicia provides for a quick and easy mechanism to determine inflation levels.

  • Publication number: 20140310879
    Abstract: The invention is directed to a sofa-bed combination, having an inflatable air mattress, rather than a foam or spring mattress. A bed base would pull out from beneath the frame of the couch. Contained on or within the bed base would be an inflatable bladder forming a mattress. Contained within an arm of the sofa would be an inflatable bladder forming an air mattress. The sofa-bed features an electric air pump, which would rapidly inflate and deflate the mattress for use or stowage.
