Definitions

  • a padding is then applied over the stockinette onto the injured limb before the application of the cast tape.
  • the padding provides a cushion and spacing between the skin and the cast tape, and protection to the bony prominences of the limb, and further aids in patient comfort.
  • the stockinette and padding together form a system that collectively provides protection to the limb while the overlying cast tape provides the necessary support and rigidity to immobilize the limb during healing.
  • the conventional stockinette and padding system is not resistant to perspiration and/or moisture, and when wet can give off odor and become uncomfortable to wear. This leads to a higher incidence of skin irritation and maceration, and in many instances may require removal and replacement of an otherwise medically-effective cast.
  • the invention described in this application discloses an undercast sleeve, which will replace both the conventional stockinette and padding. In addition to providing a satisfactory level of cushioning, this sleeve also repels water and dries quickly when wetted.
  • the water-resistant sleeve of this invention is aimed at providing more freedom to the patient and help them carry out daily routine activities with much ease. Similar efforts have been conducted in the past to develop a water-resistant undercast sleeve, as described in US Patent No. 5, 540,964 and WO2005/004765. However, none of the efforts have resulted in a successful working product.
  • the '964 Patent discloses a sleeve constructed using hydrophilic fibers with an applied hydrophilic finish.
  • the recited principle is to wick moisture away from the skin.
  • the cast material itself is relatively impervious to both air and moisture transfer, so the wicking action moves the moisture into the overlying padding and cast material, where it accumulates in the padding and in the structure of the cast.
  • the WO 765 publication discloses using microdenier fibers to wick moisture away from the skin, but this product has not proven effective for reasons similar to the '964 Patent.
  • a water-resistant orthopedic undercast sleeve comprising a tubular sheet material having hydrophobic properties and a thickness sufficient to provide both cushioning and moisture transport in a single layer between a cast and a limb onto which the sleeve is applied, and moisture egress channels formed in the sheet material for transporting moisture away from the limb, longitudinally along the length of the sleeve, and out of the space between the sleeve and cast, the sheet material having sufficient resistence to compression so as to maintain the moisture egress channels subsequent to application of a cast over the sheet material.
  • the tubular sheet material comprises a tubular fabric.
  • the tubular sheet material comprises a tubular non-woven fabric.
  • the sleeve is knitted from a hydrophobic, low filament, multifilament yarn with a filament count of at least 10 and having a total denier of between 50 and 2000.
  • the sleeve is knitted from a hydrophobic, low filament, multifilament yarn with a filament count of at least 10 and having a total denier of between 500 - 1500.
  • the sleeve is a 2 x 2 rib-knit formed a hydrophobic, low filament, multifilament yarn with a filament count of at least 10 and having a total denier of between 50 and 2000.
  • the sleeve is constructed from yarns pre-treated with a water-resistant surface coating to impart enhanced water-resistant properties to the sleeve.
  • the sleeve comprises a sleeve treated with a water-resistant surface coating to impart enhanced water-resistant properties to the sleeve.
  • the tubular knitted fabric is low moisture regain hydrophobic fiber selected from the group consisting of polyester and polypropylene, and the construction of the tubular knitted fabric is selected from the group consisting of a single knit rib construction and a double knit rib construction.
  • FIG. 1 a water-resistant orthopedic undercast sleeve product according to the present invention is illustrated in Figure 1 and shown generally at reference numeral 10.
  • the particular embodiment shown in Figure 1 is a roll-form product, and can be cut to length as needed. Indicia noting particular lengths can be placed on the product 10 to indicate where a cut may be made. The indicia may be a mark, a series of dropped stitches, or any other suitable manner of indicating a particular length.
  • the product 10 may be pre-cut into one or more lengths and packaged in that form, for example, in a bag or envelope from which a pre-cut length of product 10 is removed when needed.
  • the sleeve product 10 is placed on a limb to form a water-resistant orthopedic undercast sleeve 20.
  • the sleeve 20 can be constructed using suitable materials that provide adequate cushioning underneath a cast and are easy to mold around the injured limb, such as foam, knitted or stretch-woven textile substrate, polymeric film, plastic material or a combination of these.
  • the sleeve 20 is constructed of a suitable textile fabric, which can be constructed using any suitable organic or inorganic fiber or a blend of these.
  • the sleeve 20 is preferably constructed using a low moisture regain, hydrophobic fiber such as polyester or polypropylene.
  • the textile substrate can be either a single knit or a double knit construction.
  • the sleeve 20 is knitted using a hydrophobic fiber, such as polypropylene.
  • the yarns selected for knitting the sleeve 20 can be a monofilament or a multifilament or a blend of both.
  • the sleeve 20 is knitted using a hydrophobic, low filament, multifilament yarn with a filament count of at least 10 and having a total denier of between 50 and 2000, and preferably 500 - 1500.
  • the textile substrate can be knitted ⁇ using any suitable knit structure and design, including but not limited to plain knit, rib knit, jersey knit, loop/terry knit and an interlock knit.
  • the sleeve 20 is knitted using a rib design such as 1 x 1 , 2 x 1 , 2 x 2 or 3 x 1 rib.
  • a typical rib 2 x 2 rib knit pattern is shown in Figure 2.
  • the water-resistant performance of the undercast sleeve 20 will depend on the type of fiber, yarn and fabric construction. Hence the sleeve 20 may or may not require further treatment or finishing to enhance its water resistance.
  • the sleeve 20 can be constructed from pre-treated yarns, i.e.
  • the 20 sleeve can be treated with a suitable fluorochemical or plasma treatment, or similar product that improves or imparts a water-resistant characteristic to the sleeve 20.
  • the sleeve 20 resides against the skin and beneath an overlying wrapping of cast tape 25 to form a completed cast structure 30.
  • the sleeve 20 is intended to replace both the stockinette and padding of a conventional cast system. For this reason, the sleeve is constructed with a loft, bulk or thickness that provides adequate protection to the skin and bony prominences when applied under an orthopedic cast.
  • spacer fabrics may be suitable, with spaced-apart faces of the fabric defining an intermediate channel for transporting moisture away from both the sleeve and the cast tape.
  • the spacer fabric is formed as or into a tube and has sufficient elasticity to form to the shape of the limb in the same manner as the sleeve 20 shown in Figure 2.
  • Further alternatives may include open cell foam products in the form of sheets with channels or grooves molded or otherwise formed into the surface of the foam to serve as channels for transporting moisture away from the foam sleeve and the cast tape.
  • the sheets are formed as or into tubes and have sufficient elasticity to form to the shape of the limb in the same manner as the sleeve 20 shown in Figure 2.

Abstract

L'invention concerne un manchon à moulage orthopédique résistant à l'eau, comprenant une matière pelliculaire tubulaire possédant des propriétés hydrophobes et une épaisseur suffisante à fournir à la fois l'amortissement et le transport d'humidité dans un couche unique entre un moulage et un membre sur lequel le manchon est appliqué, et des canaux de sortie d'humidité formés dans la matière pelliculaire afin de transporter l'humidité hors du membre, longitudinalement le long du manchon, et hors de l'espace entre le manchon et le moulage, la matière pelliculaire possédant une résistance suffisante à la compression de manière à conserver les canaux de sortie d'humidité après application d'un moulage sur la matière pelliculaire.
