Definitions

  • the present invention relates generally to anatomical support cushions adapted for use in improving pelvic and spinal alignment issues during use of a wheelchair apparatus.
  • Non-ambulatory patients suffering with minor illness or simple leg bone injuries, or the like do not normally require the use of special purpose wheelchair cushions.
  • LTC long term care
  • the use of specially configured cushioning or other body positioning, orienting or supporting means may be required.
  • the present invention is intended to address this need and to provide an adjustable wheelchair cushion that can be specified, prescribed and/or used by LTC therapists to improve the efficacy of wheelchair cushioning used in this environment. The following is included to provide background information relating to some of the postural abnormalities toward which the present invention is directed, and how an LTC therapist has sought to provide, or has in fact provided, patient relief during use of a standard wheelchair and cushioning means.
  • ASIS & PSIS at equal height no pelvic tilt.
  • an LTC therapist When fitting an LTC user for a wheelchair, an LTC therapist will usually try to maintain proper patient postural alignment with a STANDARD cushion (and back support).
  • the pelvis sits with the L or R ASIS higher than the other, causing the raising up of one hip.
  • the thoracic spine curves away from the higher side creating a scoliosis over time.
  • the neck will go into lateral flexion as if the person is dropping an ear to his or her shoulder.
  • the lateral flexion will usually be towards the side where the hip is higher.
  • Pressure redistribution is the therapist's support goal whether the deformity is FIXED or FLEXIBLE.
  • FIXED the deformity should be accommodated by protecting the bony prominences from pressure by "filling in” the higher side and immersing the lower side IT.
  • the pelvis sits with ASIS higher than the PSIS resulting in the posterior pelvic tilt which produces the sacral sitting posture.
  • the patient hyperextends his or her back over the sling back of the chair, placing him or her at risk to tip the chair backwards.
  • lordosis in cervical spine causes forward neck flexion & downward eye gaze to floor/lap.
  • a cushion with medial and lateral contour is often used to promote LE alignment and pelvic stability. Appropriate cushion depth should be used to prevent the patient from sliding forward as he seeks reduced pressure behind the knees.
  • a rigid insert is often used to prevent hammocking of the seat and cushion and to keep the pelvis from collapsing into a posterior pelvic tilt.
  • a cushion with tapered adductors can be used to load the trochanters, stabilizing the pelvis in the resident's most neutral alignment.
  • a cushion with an anti-thrust component can be used to reduce forward sliding of the pelvis into posterior pelvic tilt.
  • FIXED An immersion style cushion that contours to the shape of the patient used to promote maximum pressure redistribution, minimizing peak pressures.
  • FIXED Opening seat-to-back angle in conjunction with a fixed tilt in the wheelchair is often used to match the patient's ROM limitations and minimize forward sliding.
  • the thoracic spine follows and rotates in the same direction as the pelvis. Therefore, if the right side of the pelvis is rotated more forward, the right side of the spine is rotated more forward as well. The neck will go into lateral flexion as if the person is dropping the ear to his or her shoulder.
  • the objective is to stabilize the pelvis in the patient's most neutral position - adjusting for flexible or fixed postures - to prevent further pelvic rotation.
  • One option is to apply an anti-thrust force to reduce forward migration of the pelvis.
  • FLEXIBLE use tapered adductors and a medial abductor to create leg troughs for midline LE alignment and to maintain a pelvic neutral position.
  • FIXED use a cushion with less aggressive contouring. Protect the bony prominences with an immersion-style cushion.
  • US 2003/0205920 A1 is an example of the background art.
  • This document teaches a cushion having a shaped base on which is positioned a resilient, cushioning layer.
  • the shaped base is constructed from a supportive foam and has front and lateral bolsters,
  • the cushioning layer is an inflatable air cushion having a flexible base and an array of individual air cells arranged in rows across the flexible base.
  • An object of the present invention is to provide an adjustable wheelchair cushion apparatus that can be adapted to accommodate the particular anatomical support needs of a user having postural abnormalities.
  • Another object of the present invention is to provide an improved anatomical support cushion apparatus including at least one thermoplastic elastomer honeycomb cushion panel and a plurality of selectable inserts that serve to conform, support and/or stabilize a wide variety of wheelchair user sitting positions, user anatomies and disabilities.
  • Another object of the present invention is to provide an improved adjustable anatomical support cushion apparatus for providing pelvic and trunk stability for a wheelchair user having postural abnormalities.
  • Still another object of the present invention is to provide an adjustable anatomical support cushion apparatus for maximizing functional activities of daily living for a wheelchair user having postural abnormalities.
  • Yet another object of the present invention is to provide an improved anatomical support cushion apparatus for protecting skin and preventing wounds, and/or promoting the healing of existing wounds suffered by a wheelchair user having postural abnormalities.
  • a further object of the present invention is to provide an adjustable support cushion apparatus for maximizing comfort for a wheelchair user having postural abnormalities.
  • Another object of the present invention is to provide an adjustable anatomical support cushion apparatus for minimizing unwanted skeletal movement by a wheelchair user having postural abnormalities.
  • Yet another object of the present invention is to provide an adjustable support cushion for preventing progression of postural abnormalities.
  • a still further object of the present invention is to provide an adjustable anatomical support apparatus that is breathable to permit cooling of the user.
  • Still another object of the present invention is to provide an adjustable anatomical support apparatus constructed of materials that are fast drying, and can be easily disinfected and sterilized by chemical wash, microwave treatment, detergent wash, or other means.
  • the invention is defined by the independent claim 1.
  • the present invention is directed to an adjustable wheelchair seat cushion apparatus including a resilient thermoplastic honeycomb seat cushion member and a pivotally attached base member forming a planar base upon which the upper cushion member will rest when folded about the pivot to engage and lay thereupon.
  • the base member may also be made of one or more layers of a more rigid thermoplastic honeycomb material.
  • Positioned upon the base member and disposed between it and the overlying cushion member are user and/or LTC therapist installable, prescriptively sized and shaped pelvic obliquity elements, pommel elements and/or wedge elements operative to deform the cushion member when engaged therewith.
  • Another advantage of the present invention is that in fitting the cushion apparatus for a particular user, an LTC therapist may select from a wide variety of preformed shaping elements and cushion positions therefor to customize and individually tailor the cushion apparatus for an individual user.
  • Yet another advantage of the present invention is that a single size and shape of cushion can be matched with a variety of individually selectable, preformed shaping elements to support the specific requirements of a particular wheelchair user.
  • the anatomical support apparatus may be constructed from a perforated core thermoplastic elastomer honeycomb panel that is breathable to allow perspiration removal and cooling of the apparatus user.
  • thermoplastic elastomeric honeycomb core designs and/or multiple panels of different thermoplastic honeycomb core designs may be utilized to maximize design flexibility of the improved anatomical support apparatus.
  • thermoplastic elastomeric honeycomb core is fabricated from recyclable materials that are fast drying, and easily disinfected and sterilized.
  • FIG. 1 of the Drawings depicts a conventional wheelchair 10 having disposed thereon a removable, improved anatomical support cushion 12.
  • the cushion 12 is constructed of at least one flexible thermoplastic elastomer honeycomb core panel built in accordance with the present invention. It should also be noted that although the cushion assembly 12 is particularly well suited for wheelchair applications, the cushion assembly, or analogs thereof, may also be used in a variety of other anatomical support applications (e.g., mattresses, automobile and airline seats, arm rests, etc.).
  • Fig. 2 is provided to illustrate optimal user posture when seated in a standard wheelchair.
  • Figs. 3-6 are provided to respectively illustrate postural conditions identified as pelvic obliquity, anterior pelvic tilt, posterior pelvic tilt and pelvic rotation; all are conditions that can be aided through use of the present invention.
  • Fig. 7 generally depicts the principal components of an adjustable wheelchair seat cushion apparatus 12 including a multi-layered resilient thermoplastic honeycomb seat cushion member 14 and a pivotally attached base member 16 forming a planar base upon which the upper cushion member 14 will rest when folded about the pivot 18 to engage and lay thereupon.
  • the base member 16 may also be made of one or more layers of a more rigid thermoplastic honeycomb material.
  • Positioned upon the base member 18 and disposed between it and the overlying cushion member 14 are user and/or LTC therapist installable, prescriptively sized and shaped pelvic obliquity elements 20, pommel elements 22 and/or wedge elements 24 operative to deform the cushion member 14 when engaged therewith.
