DETAILED DESCRIPTION OF THE INVENTION

[0027] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0028] Broadly, an embodiment of the present invention provides custom disposable medical device covers. The covers may be made from spun-bound polyethylene and poly-backed wood-pulp fiber (“cover material”) cut into a design pattern that is then formed to custom fit PEMFT medical devices. The cover material may include 50 gsm spunlace laminate fabric. The final design may be facilitated by the way of polyester/cotton blend or nylon thread, an elastic component, and detachable fasteners, such as but not limited to hook and loop fasteners and/or restickable tape on tab closures.

[0029] Referring to FIGS. 1 through 9, the present invention may include (1) a strap cover 10 for (strap-based PEMFT medical devices or) strap applicators 30; and (2) a disc cover 20 for (disc-based PEMFT medical devices or) disc applicators 40.

[0030] The strap cover 10, 50 may be formed from the cover material that is cut into a flat strap pattern, as illustrated in FIG. 7A, which may be sewn with a stitch down the length of the body of the strap cover 10, 50 creating a wide sleeve 12, 52 later to be creased along one longitudinal edge to form a seam with the opposing edge along a seam line 19. Tabs 14, 54 (cutout flaps) may longitudinally extend from an upper and lower edges of both ends of the sleeve 12, 52. Each tab 14, 54 may extend for five inches. Each tab 14, 54 may be substantially rectangular or oval with a tapered portion at the edge of the sleeve 12, as illustrated in FIG. 3. Detachable fasteners 16 may be connected to the same side of the tabs 14. Each detachable fastener 16 may have a removable layer 18.

[0031] The disc cover 20 may be formed from the cover material that is cut into a pouch-shaped disc pattern having an opening 24, wherein an elastic component 22 is sewn into a periphery defining the opening 24 by way of gathering stitching 21. The elastic component may have a 14-inch thickness in certain embodiments, Slots 26 may be provided adjacent to the opening 24. Each slot 26 may be dimensioned and adapted to slidably receive the handles 42 of the disc applicator 40.

[0032] The strap cover 10, 50 works by completely siding over (like a pillowcase) and covering the effective usage area of the strap applicator 30. Then, the two end tabs 14, on each end of the sleeve 12, are then folded over, removing the removable layer 18, and conveniently joining the detachable fastener 16 to the surface of the strap cover 10. 54 flaps, without stick pads, are alternatively tucked down inside front sheath of 50 body. Now the entire usage area of the strap applicator 30 is protected and protects the user from making contact with undesirable or unclean particles. After use, the strap cover 10, 50 may be disposed of, and a new one used for the next user.

[0033] The disc cover 20 works by stretching out the elastic component and placing it over the top/face of the disc applicator 40, much like a shower cap, bringing it all the way up the sides so that the two handles 42 protrude from the slots 26. The biasing of the elastic component 22 urges an associated portion of the body of the disc cover 20 snugly against the rear surface of the disc applicator 40. A portion of the disc applicator 40 protrudes through the opening 24 for application purposes. The gathering stitch 21 enables this functionality through forming a channel housing the elastic component 22. As a result, during use of the disc applicator 40, the cover material contacts the skin area being treated, and the hand that holds the disc applicator 40 will be protected. Thereafter, the disc cover 20 may be disposed of, and a new one used for the next user.

[0034] A method of manufacturing the present invention may include the following. To make the strap cover 10, 50 a manufacturer may cut the pattern out of the selective grade “cover material” designed perfectly to fit the medical device it is designed to protect. A person skilled in the art will calculate the fabric dimensions based on the relevant strap applicator 30. In certain embodiments, approximately 26 inches in length and 13 inches in width for the sleeve 12, 52.

[0035] A method of manufacturing the disc cover 20 may include cutting the cover material fabric into the (die cut) flat disc pattern shown in FIG. 8A. The disc pattern is sewn all around the outer edge with, in certain embodiments, a basting stitch using a gather presser foot, creating a ‘balloon’ with a 6″ to 7″ opening 24. The approximately 5½″ elastic component 22 may have been pre-made into a 5″ circle with ¼″ overlap fix stitch. This circular elastic component 22 may be placed and stretched over the ‘balloon’ opening and laid down with a basting zig-zag stitch (100% nylon thread) no wider than the ¼″ elastic component 22, thereby creating the disc cover 20. This exacting procedure creates a consistent opening and closing function and size of 20.

[0036] The manufacturer would then sew a seam allowance using a polyester/cotton blend thread or the like with, in certain embodiments, an approximately #3 stitch width (using approximately eight stitches per inch). The seam may be 26-inches long. The sleeve 12, 52 may then be turned right side out and pressed flat leaving crease at top/seam at bottom of the finished sleeve 12, 52, having an approximately six-inch width. The manufacturer may affix the peelable layer 18 over the detachable fasteners 16.

[0037] The components of the strap cover 10, that could be reconfigured to cause the present invention to perform a similar function, wherein the flaps 14 at each end of the approximately 26-inch sleeve body that are on opposite sides of the ‘sleeve’ and are alternatively placed to face inward towards each other.

[0038] In certain embodiments, the flaps 54, as illustrated in FIG. 9, could function by simply being tucked into a ‘pocket’ slit underneath where the PEMF coils reside.

[0039] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
