Bead Containing Patents (Class 5/655.4)
  • Publication number: 20150000042
    Abstract: A pillow relies on a shell containing two types of fill material, one comparatively smaller, granular, and characterized by a comparatively larger spring constant, and another comparatively larger, more chunky in shape, and characterized by a comparatively smaller spring constant. Below a threshold level of force (or pressure, which is force per unit area) the larger, softer, second fill material resists flow of the smaller, harder, stiffer fill material. However, upon application of a force (or pressure) above some threshold, the mixture of the two fill materials will flow to conform the pillow to the shape of a user. The pillow will then substantially stabilize in that shape in the absence of forces above the threshold level.

  • Patent number: 8732878
    Abstract: A method and apparatus are disclosed for a method for securing a patient for a medical procedure and specifically for an innovative headrest system for securing a patient for an ocular imaging procedure. The approach avoids the need for linkages and sliding rods and such. Instead, it relies on three independently movable face rests (two for the forehead or temples and one for the chin) each with a deformable cushion that is urged into conformity with the patient's head and chin during an adjustment phase of operation. Once a comfortable position and suitable conforming shape is achieved, the positions of the face rests are rigidly fixed and the shape of the cushions are rendered rigid and non-deformable, by application of a light vacuum, for the procedural or imaging phase of operation.

    Abstract: An article of manufacture is made by filling a container with expanded thermoplastic elements that are in a non-cured state and that possess a degree of latent foaming ability. After filling the container with the non-cured elements, the elements are allowed to cure under ambient conditions during which the blowing agent remaining in the elements in a vapor state condenses allowing air to be drawn in while the elements expand. This expansion of the elements distends and rigidifies the container where the container is allowed to expand or places an item packaged within a container of rigid construction under a tight fit.

    Abstract: A flexible support structure of a seat cushion, such as a wheelchair cushion, has an upper surface with a support contour having relief areas for establishing relatively less pressure on skin adjacent to bony prominences of a user's pelvis and having a support area for establishing relatively more pressure on skin covering a tissue mass spaced from the bony prominences. A slit is formed in the rear corner of the support structure and an insertion member is inserted into the slit to change a position of the support area to thereby adjust the support contour for better support of the pelvic area. A cover encases the support structure to resist outward deformation of the support structure. The cover has an extension portion that expands the cover at the rear corner to increase a dimension of the cover to encase an increase dimension of the corner caused by the insertion of the insertion member.

The cushioning device is capable of receiving a physical object that applies a force to the cushion. When the force is initially applied to the cushioning device, the cushioning device is deformed to conform to the physical object from its original shape. When the physical object is not applying the force, the cushioning device reverts to a shape that is close to but not identical to the original shape, except for a limited number of materials such as molded elastomeric materials. In addition, the pressure exerted by the cushion on the physical object will reduce pressure that would cause tissue damage and lead to decubitus ulcers.

  • Patent number: 6651282
    Abstract: A flexible, crescent shaped pillow to assist mothers to maintain an anatomically correct alignment between mouth and nipple while breast feeding. This alignment is a key factor in ensuring optimum flow of milk. The pillow is both highly flexible and supportive. These are the key features that make it an effective aide to breast feeding mothers. These properties are achieved through the use of a low density bead filling which can shift and flow within the casing, thus providing the correct support where it is needed. The pillow is designed to be used while feeding in a variety of positions and from either breast. Use of the pillow also reduces fatigue and stress for both baby and mother while nursing. The bead filling allows for the passage of air and liquids through the pillow. This contributes to increased safety in terms of reduced risk of suffocation. and less opportunity for the growth of mold and bacteria.

  • Patent number: 6611980
    Abstract: The present invention is directed to a custom-contoured cushion for a wheelchair or other seating device and a method of making the same. In one embodiment, the novel custom-contoured cushion is comprised of a stretchable bag filled with soft and resilient closed-cell foam pellets adhered together by and/or embedded within an elastomeric polymerizable adhesive. The pellets do not absorb a significant amount of the adhesive and, after molding, remain sufficiently soft and resilient to provide a comfortable and durable cushion. Alternatively, the cushion contains soft and resilient pellets, but does not contain the elastomeric polymerizable adhesive. In the first embodiment, the custom-molded, custom-contoured cushion is made by mixing the pellets with the adhesive to form a pellet/adhesive mixture, positioning the user on a bag filled with the pellet/adhesive mixture, molding the mixture around the user to provide cushioning around the user's seating surface, and allowing the adhesive to cure.
