referring now to fig1 - 4 , and as best illustrated in fig1 , a dressing or compress 100 is illustrated having a lower shell 102 and a flexible upper backing 104 which are joined or otherwise fastened to one another to form a series of enclosures 106 there between . the enclosures are provided for the containment and relatively uniform distribution of a plurality of fill granules 108 placed therein . the enclosures may be fashioned as filled pods which are draped from the backing . the shell 102 forms the contact surface of the dressing or compress used to drape or form the bottom of the filled enclosures which are to be placed against the tissue to be treated , and to conform to the shape of the treatment area . the backing forms the smoother outer surface of the dressing or compress facing away from the treatment area . the enclosures 106 may be defined as hexagons using patterned seams 110 for local symmetry and efficient regular plane division . an illustrative hexagonal pattern 200 of enclosures 202 is illustrated in fig2 . the enclosures might also be fashioned as circles , octagons , or of any desired shape as may be appropriated for the desired treatment . the enclosures may be selectively sized as appropriate to the application . each hexagonal shaped enclosure 202 has a lengthwise dimension 204 extending from a first corner to an opposite second corner thereof . for example , and not by way of limitation , this dimension may be in the range of from approximately one inch to approximately four inches in length . large treatment areas such as the human torso or appendages may best be served with enclosures having a dimension 204 extending lengthwise for approximately 4 inches . highly contoured areas such as the face may best be served with enclosures having a dimension 204 of approximately 1 inch in length . an alternate dressing or compress 300 is illustrated in fig3 , having a plurality of hexagonal patterned enclosures 302 . each of the enclosures may also be formed as a channel - like rectangle , as illustrated in fig4 . the embodiment of the dressing or compress 400 is formed to have several channel enclosures 402 formed within a wrap compress having securing ties 404 . so constructed , the dressing or compress 400 may be provided for the treatment of soreness or strains of the human back . the size of the enclosures and overall dressing are selected to serve the desired treatment . selected single sites for treatment such as the eye may best be treated using a single enclosure dressing or compress appropriately sized and shaped to rest comfortably in the eye hollow of the human face . the dressing or compress may be shaped as a regular or irregular polygon , any smooth closed curve , or any closed combination of line segments and smooth curves . the invention is not limited to constructions conforming to or only serving the human body . the invention provides a potentially useful treatment for the ailments of mammals and any animals benefiting from the healing properties of moisture and / or heat therapy . a fluid - permeable , i . e ., a vapor - permeable and / or a liquid - permeable protective outer cover ( not illustrated ) may be provided to encompass the compress . this may be preferable to limit contamination of the dressing or compress . for the treatment of open wounds , an uncovered disposable dressing ( not illustrated ) may be preferred for optimal formable contact with , and healing of , the exposed tissues . the fill contained within the enclosure or enclosures may comprise a synthetic porous crystalline granular aluminosilicate zeolite , commonly used as a molecular sieve material , or other substances with similar properties . the fill material may further comprise other inert additives and physical matrices without affecting the antimicrobial and hydrous efficacies of the fill . silver loading of the fill may be attained by the process of ion - exchange , as known . in this process , a solution containing atomic silver or a composition of silver bathes , or is passed through , a bed of the fill granules 108 ( fig1 ). an ion - exchange column method , as known in the art , may be performed in which an aqueous solution containing atomic silver or a composition of silver may be passed through a column bed of the fill granules , and the eluted solution may again be passed through the bed or may receive additional silver and then be again passed through the bed . various ion - exchange schedules known in the art may be applied to produce retention of the silver . the final content by weight of the atomic silver or silver composition may be as high as twenty percent of the final loaded fill granules . the loaded fill granules produced by ion - exchange will exhibit high retention of the silver even under subsequent exposure to fluids and microwave irradiation . the fill granules may comprise a blend of both loaded and unloaded zeolite or a substance retaining silver . the presence of the atomic silver or silver composition will not interfere with the useful properties of the fill granules such as the moisture desorption and adsorption properties which may be desirable in the use of the dressing or compress . the inherent hydrophilic nature of the zeolite provides that a substantial water content is available therein by absorption from the atmosphere . the water so absorbed may be sufficient , or may be supplemented by manually added water , for providing the microwave responsive water content of the dressing or compress . the compositions of silver used may include but are not limited to , silver compounds , and silver salts such as silver chloride and silver nitrate . the presence of the silver within the fill granules contained in the enclosure of the invention provides anti - microbial properties to the dressing or compress . the ion - exchange loaded fill granules will retain the silver despite microwave heating as may be required in the use of the dressing or compress , which prevents the release of silver into a treated wound if the invention is used as a dressing . further , the retention of the silver within the fill granules provides assured antimicrobial performance in a reusable and potentially washable , if so desired , moist heat therapy compress . in the described embodiments of the invention , the lower shell and the upper backing are each constructed of materials known in the art . each may therefore be comprised of multilayered laminates , for example , with pore sizes selectable to meet the moisture transmission and retention properties desired for the specific treatment sought . the dressing or compress is adapted to be placed and to remain in intimate contact with the area to be treated to maintain a heated and / or moist environment thereabout . dressing or compress constructions using woven textiles of natural fibers have been found to have limited spatial conformance to the various shapes , dimples , wrinkles and joints offered by the human body , although these materials may be used if so desired . accordingly , preferred dressing or compress constructions will use formable woven and non - woven synthetic materials or combinations thereof which may include , but are not limited to , synthetic olefin , polyester , urethane , and nylon . the shell and the backing may be fastened together across the area of the dressing or compress with a fill material , the fill granules 108 , received there between . the shell and the backing may be fastened to one another by methods which may include , but are not limited to , adhesive attachment , rf welding , ultra - sonic attachment , sewing , or patterned heat application using a template or forming die to form a seal . to provide for the secure placement of the dressing or compress , peripheral or attachment fastening devices may be included which may comprise the desired number of velcro ® fasteners , adhesives , high tactility polymer materials , and / or material ties . throughout the construction of the dressing or compress , attention and care is taken in the selection of materials regarding thermal response to microwave heating . for design simplicity , all synthetic , microwave non - responsive materials may be selected to provide that the fill and / or water content of a moistened dressing or compress provide the only substantial thermal response to microwave irradiation . although several embodiments of the invention have been disclosed in the foregoing specification , it is understood by those skilled in the art that many modifications and other embodiments of the invention will come to mind to which the invention pertains , having the benefit of the teaching presented in the foregoing description and associated drawings . it is thus understood that the invention is not limited to the specific embodiments disclosed hereinabove , and that many modifications and other embodiments are intended to be included within the scope of the invention . moreover , although specific terms are employed herein , they are used only in a generic and descriptive sense , and not for the purposes of limiting the described invention . the words “ a ,” “ an ,” or “ the ” can mean one or more , depending upon the context in which the words are used hereinabove .
