  • Patent number: 10314752
    Abstract: Disclosed are apparatus and methodology for reducing humidity (i.e., moisture) and/or heat within and/or adjacent a patient support mattress, without requiring any electrical power. A spacer fabric is used to create a non-crushable area of support below a patient's core area, where moisture and heat more commonly buildup. Integrated air cells in the mattress have resilient elements such as open-celled foam interiors. The air cells are connected by air tubing to the spacer fabric, and the mattress is otherwise vented externally from the spacer fabric. As a result, the patient's movement causes air to be expelled from or drawn into the air cells, which in turn results in air movement in the spacer fabric below a patient or user, resulting in cooling effects by removing moisture and/or heat, all without requiring external or internal electrical power.

  • Patent number: 8893340
    Abstract: A mattress cover is disclosed for redirecting shear on a patient's skin away from the areas of the body relatively more likely to develop decubitus ulcers. The mattress cover includes an upper portion designed to cover the topside of a mattress, and at least one shear transfer zone attached to an underside of the upper portion of the mattress cover. The shear transfer zone(s) may be made of a low shear material so as to create a low friction interface between the mattress and the mattress cover to reduce shear forces exerted by the mattress. Additionally, the shear transfer zone(s) may be arranged such that a large portion of the shear forces exerted by the mattress can be redirected to areas of the body that are relatively less likely to develop decubitus ulcers.

  • Publication number: 20130104312
    Abstract: A mattress and a capacitive immersion system for adjusting the support that the mattress provides to a user are disclosed. In one embodiment, a mattress includes one or more air cells and a capacitive immersion system. The system relates generated capacitance between conductors mounted to an air cell to a pressure inside the air cells on which the conductors are mounted. More specifically, the measured capacitance may be related to a distance between the conductors. This distance may then be related to pressure with the air cells. The air cell may be inflated or deflated as required or desired to maintain a suitable minimum distance or distance that a user finds to be subjectively comfortable.

  • Patent number: 8397327
    Abstract: An insert for a bed facilitates use of a mattress having one cross-sectional profile with a bed frame having a different cross-sectional profile. An insert includes a base extending between sidewalls which have various contoured surfaces. The contoured sidewall surfaces enable the insert to be disposed in a bed frame in association with a mattress. Inner surfaces of the sidewalls are configured to accommodate receipt of a mattress while outer surfaces of the sidewalls are configured for the insert to be disposed in a bed frame. The surface sidewalls may further be configured to provide the insert with a safety feature which prevents or reduces the likelihood of a user falling from the side of a mattress associated with the insert.

  • Publication number: 20100281618
    Abstract: A bladder comprising an outer and inner surface having a length, height and width, first and second ends, and an internal volume. A support structure is disposed within the bladder and has a length, width, height as well as an inner and outer region. The outer region of the support structure comprises support projections which define openings in the outer region of the support structure. The support projections have an engaging end which contacts the inner surface of the bladder and exerts force upon the inner surface of the bladder. The support projections maintain the internal volume of the bladder in a no-load sate. The openings in the support structure allow air to move freely in the bladder versus a solid support structure lacking openings. This aids in distribution of air within the bladder and provides air-like pressure management and comfort in addition to the structural support provided by foam inserts.

  • Publication number: 20100043143
    Abstract: Disclosed are apparatus and methodology for controlling humidity (i.e., moisture) within and/or adjacent a coverlet associated with a multi-layer air mattress. Humidity sensors may be incorporated at selected locations within the coverlet and coupled to a controller that is configured to provide a closed-loop control signal to vary air flow rate through the coverlet to control the rate of moisture adjustment, such as removal. In part, present subject matter may include a combination of a Low-Air-Loss (LAL) topper, having a pair of humidity sensors, one of which is at an inlet to the LAL topper and the other of which is at a selected one of existing outlets of the LAL topper. Air flow through the LAL topper is kept constant, in accordance with its basic operation, while the two humidity sensors are part of a closed-loop feedback control system, which adjusts the humidity of the air being input at the inlet.

  • Patent number: 7444707
    Abstract: A foam chair cushion having transverse support ribs is provided for reduction of shear stress between a person's skin and the surface of the chair cushion. The chair cushion may include transverse, lateral support ribs upon the support surface of the cushion. The support ribs have a predetermined cross-sectional geometry that is curvilinear, with a superior aspect generally disposed for receipt of a person and a inferior aspect opposite. The inferior aspect of the cross-section of the support ribs may undercut the portion of the support ribs vertically above it. Having such cross-sectional geometry, the support ribs are directionally oriented, either toward the one end or the other of the chair cushion. The chair cushion may include support ribs that are directionally oriented toward the foot of the chair in regions adapted for the person's upper torso, buttocks, and lower legs, and directionally oriented toward the head of the chair in a region adapted for the person's thighs.

  • Patent number: 7296315
    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: 7100229
    Abstract: A foam mattress system having transverse support ribs is provided for reduction of shear stress between a person's skin and the surface of the mattress system. The mattress system may include a mattress to be used independent of other mattresses or springs, or a mattress pad to be used atop other mattresses or springs, and either may be used on both a flat bed and a bed with an inclined torso section. The mattress system includes transverse, lateral support ribs upon the support surface of the mattress. The support ribs have a predetermined cross-sectional geometry that is curvilinear with a superior aspect generally disposed for receipt of a person and a smaller inferior aspect opposite. The inferior aspect of the cross-section of the support ribs may undercut the portion of the support ribs vertically above it. Having such cross-sectional geometry, the support ribs are thereby directionally oriented, either toward the foot or toward the head of the mattress system.
