    WATER RESISTANT ARTICLE FOR POSITIONING IN A MEMBER
    This order claims priority for North American Provisional Order No. 61 / 312.425, which is hereby incorporated by reference in its entirety.
    TECHNICAL FIELD AND BACKGROUND OF THE INVENTION
    The present invention generally relates to the field of medical bandage products, and more particularly to a water-resistant orthopedic device, consisting of synthetic monofilament yarns for use in molding, splinting, padding or general protection of the anatomy.
    Traditionally, cotton mesh fabrics and bandages have been used to protect and soften the skin and bony prominences before applying a mold or splint. Materials conveniently used in these types of medical products include both natural and synthetic materials. Although natural materials such as cotton typically provide greater comfort than synthetic materials, natural materials are prone to moisture absorption and are extremely difficult to dry if wet. Thus, great care must be taken by the patient to keep the material dry during daily activities, such as bathing. In contrast, although synthetic materials are more resistant to water absorption, they are typically less comfortable for the patient and are therefore not normally used as submolde padding.
    Therefore, it would be desirable to provide a medical bandage product for use as a
    Petition 870190116227, of 11/11/2019, p. 12/16
    2/7 submolde or other application that covers both the comfort provided by natural materials and the water resistance properties of synthetic materials.
    To overcome the disadvantages of the prior art, the medical bandage products described above, in one aspect, a medical bandage product is provided in this document constructed from several fibers composed of a plurality of thin monofilaments generally arranged in parallel to provide a soft texture and resistance to moisture absorption.
    In another aspect, a water-resistant breathable fabric formed or woven into a circular tube is provided that fits snugly over a limp or anatomical extremity.
    In yet another aspect, the fabric is interwoven to provide a flat or 3D geometry.
    In yet another aspect, the construction of the medical bandage product makes the tissue very open, allowing the underlying skin to breathe effectively during use.
    In yet another aspect, the fabric includes about 342 openings // in2 (53 openings / cm 2 ) in a relaxed manner.
    In yet another aspect, the fabric is devoid of elastic fibers to improve conformability, however it has an 'elastic' tendency created by the interlaced structure, which allows the bandage to comfortably adapt over the limb / anatomy.
    In yet another aspect, the type of fiber allows the water to escape and be drained very effectively through the mold or, splint, thus allowing the skin to breathe and dry naturally.
    3/7
    In yet another aspect, the medical bandage product is devoid of chemical finishes to make the fabric water resistant, thus eliminating skin sensitization problems.
    In yet another aspect, monofilaments are uncoated synthetic fibers.
    In yet another aspect, the monofilaments are nylon or nylon 66.
    In yet another aspect, the monofilaments are polypropylene.
    In yet another aspect, the filaments are substantially parallel and range from about 10 to about 20, so that the fabric is flexible and soft to the touch.
    In yet another aspect, the fabric has a mass per unit area of about 20 g / m 2 or more, and can preferably range from 20 g / m 2 to 120 g / m 2 .
    Additional features and advantages of the invention will be defined in the detailed description below, and in part will be readily apparent to persons skilled in the art from that description, or recognized by the practice of the invention, as described in this document.
    BRIEF DESCRIPTION OF THE DRAWINGS
    The subject that is considered as the invention can be better understood by reference to the following description, taken in conjunction with the figures in the associated drawing, in which:
    Figures 1 to 7 are several enlarged views of portions of the fabric according to an embodiment of the invention;
    4/7
    Figure 8 is a perspective view of a tubular mesh fabric form of the invention;
    Figure 9 is a view illustrating the application of the tubular mesh fabric of Figure 8 to the forearm; and
    Figure 10 is a view illustrating the application of the fabric in a flat form to the wrist and forearm.
    DETAILED DESCRIPTION OF THE INVENTION
    The present invention will now be described more fully below with reference to the accompanying drawings in which exemplary embodiments of the invention are presented. However, the invention can be realized in many different ways and should not be construed as limited to the representative modalities set forth herein. The exemplary modalities are provided so that this disclosure will be both exhaustive and complete, and will fully convey the scope of the invention and allow a person normally skilled in the art to make, use and practice the invention.
    Referring now to figures 1 to 7, photos of images of an interlaced fabric 20, constructed from bundles of monofilament fibers the fine 22 are shown. Each thread of the fabric includes several thin monofilaments, usually arranged in parallel in bundles, to provide a smooth texture and a structure that does not unduly run or fray. The use of multiple monofilament yarns significantly increases the surface area of the fabric and reduces surface tension, which allows fluids and vapors to pass quickly through the fabric and allows bandages and sleeves formed therefrom to dry much faster upon exposure to moisture. This is an advantage
    5/7 distinct and significant over the common practice of using relatively large wires.
    Under normal circumstances, monofilaments of the type used in the present invention would be hard and inflexible, and therefore, could be uncomfortable against the skin. This problem is overcome in the present invention by the use of a single filament divided into multifilaments of the fine monofilaments. In an exemplary embodiment, the rather bulky bundle of nearly parallel filaments is between about 10 and about 20 monofilaments to provide the desired fabric flexibility and softness.
    A suitable example of synthetic monofilament includes, but is not limited to, nylon or nylon 66 monofilament. Other synthetic yarns, for example, polypropylene, can be provided in bundles to achieve the same or similar result. The porosity of the tissue is structured to dry quickly and allow the skin to breathe, and in a specific embodiment, the tissue structure has a mass per unit area of about 20 g / m, and can preferably vary between 20 g / in 2 to 120 g / in2. The opening of the tissue allows the skin to breathe effectively during use, and in a specific modality, the tissue structure results in about 342 openings / in 2 (53 openings / cm2) (in a relaxed way).
    The fabric can be woven into a circular knitting machine, also known as a weft knitting machine, to provide sleeve geometry to be placed over a limb. The fabric can also be knitted on a warp knitting machine in the form of
    6/7 a flat or 3D geometry fabric, which can be wrapped from lameness. The knitting construction can be produced on a single gauge and cylinder or on a double needle bed machine.
    The use of several thin filament fibers eliminates the need for chemical coatings for water resistance, thus eliminating skin sensitization problems. The use of several fine monofilament fibers also eliminates the need for incorporating elastic fibers into the fabric to improve conformability, since an elastic tendency is inherently created by the braided structure and the use of fine monofilament, which allows the fabric to adapt to the underlying anatomy.
    With reference to figure 8, the fabric can be knitted in a seamless tubular mesh fabric 24 or sleeve, having any desired length. With reference to figure 9, the tubular mesh fabric 24 is shown applied to the patient's forearm. Such a sleeve is useful, for example, in use below the mold and in bandage support covers, particularly for injured human limbs, such as legs and arms, and even fingers, such as fingers or toes. Referring to figure 10, the fabric may alternatively be knitted in a flat geometry 26 for use as a wrap around a member, or to be sewn into a tube.
    In an exemplary construction, a mesh fabric was produced with a diameter of 7.62 cm, although different diameters are possible. In the 7.62 cm diameter construction, 10-fold 66 22 dtex nylon monofilaments were combined to produce a 22 0 yarn
    7/7 dtex. Next, a l & l rib knitting structure (l & l Rib) was produced using a circular knitting arrangement with 136 needles with an indicator diameter of 900 mm and 9 rows / cm 2 . The product was then annealed after knitting at 95 ° C. for 4 minutes under vapor pressure of 18.14 kg. The annealing process stabilized the knitting. For example, rolls measuring 7.62 cm in diameter and 25 meters long were produced.
    In another example, yarns having between 10 and 20 filaments were used to make a circularly knitted glove according to another embodiment of the invention. Sleeves with 22 dtex are also possible. In yet another embodiment of the invention, it is believed that the surface area of a dtex 220 wire, formed by 10 small wires, has a larger surface area and surface tension, so that the entry of water is delayed mechanically without the need for a finish. . It is believed that below 26 rows per inch and 20 needles per inch the product runs or shreds undesirably.
    Although the specific embodiments of the present invention have been described, it will be apparent to those skilled in the art that various modifications of this can be made without departing from the spirit and scope of the invention. Thus, the foregoing description of the preferred embodiment of the invention and the best way to practice the invention are provided for illustrative purposes only and not for limitation purposes.
