Definitions

  • the present invention relates to the field of orthopedic braces.
  • a typical brace includes rigid structural components dynamically linked together by hinges, such that the axes of the hinges align with the joint being stabilized.
  • the rigid structural components are secured to the body of the wearer above and below the joint by flexible straps to support and protect the joint when the wearer is active.
  • a knee brace can be used to stabilize the knee joint which connects the upper leg or femur with the lower leg or tibia.
  • Typical knee braces comprise an upper leg cuff that generally conforms to the shape of the upper leg above the knee joint and a lower leg cuff which generally conforms to the shape of the lower leg below the knee joint.
  • the upper and lower leg cuffs are connected to each other by hinges in alignment with the knee joint.
  • a plurality of straps are typically used to secure the cuffs to the leg.
  • Such straps are adjustable and are periodically re-tightened as the brace becomes loose due to fluid loss in the joint and leg from compression associated with the tightened cuffs.
  • U.S. Patent No. 6,623,439 to Nelson et al. is directed to a knee brace secured to the leg with a plurality of straps.
  • the present invention includes a vacuum system and orthopedic brace that effectively prevents the loss of firm contact between the limb and the brace, therefore minimizing, if not completely eliminating the traditional adverse changes.
  • the present invention is directed to a vacuum orthopedic brace and method including the use of an inner sleeve or liner, first and second cuffs, and a hinge connecting the cuffs.
  • the cuffs includes a fabric liner or other porous material to act as a wick, and a gasket surrounding the wick material.
  • a valve is preferably provided in the cuff for drawing air from between the cuff and the liner, i.e. to create a vacuum.
  • an external, internal or integrated chamber or rigid reservoir is preferably included, and in communication with the wick filled area between the cuff and liner, to hold a vacuum.
  • the sleeves are preferably made of polyurethane or silicone, the sleeves may be single-piece sleeves or multi-piece sleeves, and may be tubular and slidable onto the an arm or leg, or the sleeves may be wrap-around type sleeves with a sealing edge, e.g. sealing tape, to ease the installation of the sleeves and brace.
  • a disconnectable hand-pump or otherwise actuated pump may be used to connect to the valve and draw the vacuum between the cuff and the liner or skin.
  • FIG. 1 is a side-view of an orthopedic brace of the present invention.
  • FIG. 2 is a cross-sectional view of a cuff of the brace of FIG. 1.
  • FIGS. 1-6 an orthopedic brace 10 is shown, for example, for placement on a leg of a human being.
  • the brace 10 is a knee brace, but the invention applies to all types of orthopedic braces including braces for use with feet, ankles, hips, pelvis, back, neck, shoulders, elbows, wrists and hands, for example, as would be appreciated by those skilled in the art.
  • FIG. 1 illustrates a preferred embodiment of a orthopedic knee brace 10 according to the present invention.
  • the illustrated brace 10 is intended for use on the left leg and includes a first or upper cuff 12 (or rigid member) for positioning above the knee joint and a second or lower cuff 14 (or rigid member), for positioning below the knee joint, and one or more ' hinges 16 (e.g. polycentric hinges) located .along the axis of the knee joint, on one or both sides thereof.
  • Each cuff 12, 14 is preferably a generally. U-shape structure, which, for example, may be fabricated of a polymer plastic, carbon fiber material or any other suitable rigid or semi-rigid material appropriate for orthopedic braces.
  • the brace 10 maintains the associated body portions in proper alignment and thereby prevents injuries caused by lateral joint displacement.
  • the hinges 16 may be configured with a limited range of rotation to prevent hyperextension of the joint.
  • the brace 10 may also be provided with a plurality of straps for securing first cuff 12 and the second cuff 14 to the associated portions of the extremity.
  • the illustrated brace 10 is preferably used to prevent injuries to the joint; however, the brace may also be used to support the joint during rehabilitation after an injury.
  • FIG. 2 shows only a cross-sectional view of the upper cuff 12, it is to be understood that the following description thereof regarding the vacuum feature defined below applies also to the lower cuff 14.
  • Each cuff 12, 14 includes an inner wall 13 for placement towards the skin of the user.
  • a liner 24 is preferably used as a skin interface between the brace and the skin of the user.
  • the inner wall 13 of the cuff includes a sealing gasket 26 around a periphery thereof.
  • An outer rigid wall 16 is carried by the inner wall and defines a vacuum reservoir 20 therebetween.
  • a porous or wick material such as felt or Dacron, for example, is within- the area surrounded by the gasket 26.
  • a valve 22 e.g. one way valve
  • the integrated vacuum reservoir or rigid reservoir 20 is preferably included, and in fluid communication with the wick filled area between the cuff and liner 24, to hold a vacuum.
  • a reservoir may also be external to the cuff.
  • a disconnectable hand-pump or otherwise actuated pump may be used to connect to the valve 22 and draw the vacuum between the cuff and the liner or skin.
  • the brace 10 is placed at the treatment site of a user and the cuffs 12, 14 are positioned about the involved limb structure with the liner 24 therebetween.
  • a pump is used to draw air from the wick filled area via the valve 22 and communication hole 30.
  • the vacuum chamber is also charged with a vacuum to maintain the vacuum in the wick filled area between the cuff and the liner 24.
  • Support straps 18 may also be used to aid in installation of the brace but do not need to be retightened or adjusted while the brace is being worn.
  • the vacuum feature of this orthopedic brace effectively prevents the loss of firm contact between the limb and the brace, therefore minimizing, if not completely eliminating the typical adverse changes including the loss of fluid in the adjacent limb portions.
  • the cuffs 12, 14 can be standardized cuffs (i.e. "off the shelf” cuffs) or may be custom molded.
  • the liner 24 may be a tubular sleeve slidable onto the body portion or it may be a wrap-around type sleeve including a sealing overlapping edge.
  • the liner 24 may include separate liner portions associated with each of the cuffs, and the sealing gasket 26 may be formed integrally therewith.
  • the liner 24 is preferably a silicon or urethane liner and may be standardized or custom made as necessary. For example, the liner may be made by body doubling the treatment area of the body portion with pourable silicon, as would be appreciated by the skilled artisan.
  • the ankle area would likely be such a body portion that may benefit from a custom made liner as discussed. -Additionally, more than two cuffs may be used if necessary for a specific application.
  • Advantages of the orthopedic device of the present invention include, but are not limited to: volume control; wound healing; maintaining intimate fit of brace and improving user compliance due to the importance of total contact and an intimate fit with the brace over the treatment site. In the past as the user's body portion would lose contact due to volume loss and the squeezing effect of the brace at the site, the user would have to tighten the brace up by hand which resulted in patient compliance issues and only a certain amount of tightening could be accomplished by the patient or practitioner.
  • the tissue rehydration is being accomplished by the vacuum effect being placed on the effected site keeping loss of fluid to that area to a minimum. This in turn may improve healing, e.g. for diabetic patients, and provide another option to surgery.

Abstract

L'invention concerne une orthèse à vide et une méthode de support comprenant l'utilisation d'un manchon ou d'une garniture interne, d'une première et d'une seconde embrasse, et d'une articulation reliant les embrasses. Les embrasses comprennent une garniture de textile ou d'un autre matériau poreux agissant comme un drain, et un joint d'étanchéité entourant le matériau de drainage. L'embrasse comprend de préférence une soupape permettant d'extraire l'air se trouvant entre l'embrasse et la garniture, et créer ainsi un vide. En outre, cette embrasse comprend de préférence un compartiment ou réservoir rigide externe, interne ou intégré, communiquant avec la zone remplie de matériau de drainage comprise entre l'embrasse et la garniture, et permettant de maintenir un vide.
