Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates in particular to composite fabrics and therapeutic abutments for the human body.

[Conventional technology and problems]

Accidents and injuries resulting from occupational or recreational exercise are common. Such injuries and associated pain often result from weight-bearing, repetitive strain, and other reasons, resulting in damage to muscles, locks, ligaments, and other tissues. Such injuries are not only painful, but also involve the need to limit or avoid movement of the body, including the injured area, resulting in loss of time and reduced work efficiency and recreational activities.

Non-human animals, especially horses, are subject to similar injuries and associated problems.

The usual treatment for such injuries involves the application of elastic bandages, which create compression and are sometimes accompanied by restriction of movement. Other treatments include application of cold bags, heat, and immobilization of the limb or other injured area.

The traditional method of applying a therapeutic patch to the injured area is
Described in the following US patents:

U.S. Pat. No. 2,787,266 describes a material used as an elastic surgical bandage formed by laminating fabric and porous foam latex.

U.S. Pat. No. 3,092,110 describes a thermal-support sleeve made of rubber, such as foam rubber or foam neorene, lined with fabric. The fabric lining is intended to absorb perspiration and protect the skin of people who have allergic reactions when in contact with rubber or neorene.

U.S. Pat. No. 3,613,681 discloses a closed cell elastic foam elastomeric sleeve having inner and outer tensile surface coverings such as knitted materials.

No. 3,892,239 describes a thermal laminate material that includes a thin rubber layer in a laminate structure with a cross section that gradually decreases in one direction. Both sides are covered with knitted fabric and the inner surface is serrated. Also, patent No. 4,
No. 121.582 discloses a laminated sheet structure that appears to be substantially equivalent to the disclosure of Patent No. 3.892,239.

U.S. Pat. No. 4,084,586 describes a generally cylindrical resilient abutment that is extendable in all directions to grip and apply pressure to the surface of the surrounding body part. The pad consists of a closed cell neoprene rubber layer with a nylon knit material bonded to the inner and outer rubber surfaces to provide a relatively low coefficient of friction textile surface.

No. 4,414,970 discloses a moisture-vapor permeable elastic bandage consisting of an elastomeric film sandwiched between inner and outer fabric layers.

No. 4,433,024 discloses a water vapor absorbent particle-filled sheet material with low thermal insulation values for use in clothing.

Many conventional elastic bandages or wraps are not anatomically precise enough to provide uniform compression and long-term comfort. The disadvantage of conventional heat sources is that they only heat for a limited period or time, or in the case of heat transfer pads, they limit the user's mobility and cannot be used while the user performs other exercises. Can not.

Many conventional dressings used to treat injuries such as those described above are often unattractive to wear and use, and thus are not accepted. These patches do not allow air circulation adjacent to the skin and, as a result, directly contact the skin, inhibiting sweating and causing softening, wrinkles or maceration of the skin.
Accompanied by fatigue of the muscles below it. Finally, conventional wraps and patches are preferably non-irritating to the skin's surface.

[Object and effect of the invention]

The present invention provides a therapeutic abutment with excellent heat retention, compressibility, and skin irritation by providing a composite fabric structure and an anatomically contoured abutment formed from the fabric. The aim is to overcome the above-mentioned and other drawbacks of the prior art.

The composite fabric includes three layers. The outer layer is a conventional nylon single chassis knit fabric that stretches in all directions to provide an attractive protective cover. The inner layer in direct contact with the user's skin is a knitted nylon fabric consisting of threads interlaced in a looped pile that contacts and stimulates the user's skin.

Sandwiched between the inner and outer fabric layers is a resilient foam layer of a closed cell low density copolymer (neobrene) polycycloprene. The inner and outer fabric layers are adhesively bonded to this foam layer.

The outer fabric layers bond together to protect the protector made of the fabric of the present invention. The intermediate copolymer polychloroprene layer provides light compression against tissue swelling and acts as an insulating layer to retain body heat within the inner layer and the injured area of the body. The inner layer also absorbs sweat from the skin's surface and retains this moisture. This keeps the skin surface itself relatively dry, reducing skin maceration and underlying muscle fatigue. Because the nylon fibers used in the inner layer absorb relatively little moisture, they do not become saturated with sweat and cause discomfort to the wearer like other fibers. The open structure of the inner layer also retains a significant amount of air between the intermediate layer and the skin, allowing air circulation to ventilate the skin surface and thus prevent excessive sweating.

The composite fabric of the present invention optimizes the retention of body temperature in the injured area12
, which maintains body temperature and has a therapeutic effect. Importantly, contact and friction between the pile surface of the inner fabric layer and the skin surface causes skin surface irritation, which expands the capillary bed at the skin surface and increases blood circulation. As a result of the ventilation provided by the inner layer, the skin surface beneath the inventive appliance remains comfortably dry during normal movement. During strenuous exercise, this skin surface area normally sweats.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

As illustrated in FIGS. 1, 5, 6, 7, 8, 9, 10 and 11, the therapeutic abutment according to the present invention can be applied to injured areas of the body. is formed by knitting a sleeve-like enclosure that conveniently encloses the This is accomplished by sewing together suitably shaped sections of the composite material 10 of the present invention, which will be described in detail below.
