as shown in the drawings wherein like numerals relate to like elements throughout , the invention is embodied in a surgical floor mat 11 comprising four compressed sponge sections 13 and a waterproof and foldable sheet 15 . the compressed sponge sections 13 are adhered to the foldable sheet 15 by way of glue ( not shown ) or some other means commonly known in the art of securement . edges 17 of the foldable sheet overlap top surfaces 19 of the compressed sponge sections 13 by approximately 5 / 8th of an inch . edges 17 of the foldable sheet 15 are stitched or glued to the top surface 19 of the compressed sponge sections 13 . alternatively , as shown in fig1 stitches 21 at about 3 / 8th of an inch inwardly ensure that the edges 17 of the foldable sheet 15 are properly adhered to the top surface 19 of the sponge sections 13 . the glue ( not shown ) also has a tendency to seal any holes which might be created by the stitches 21 . between each of the sponge sections 13 is a flow canal 22 having a dimension shown as &# 34 ; z &# 34 ; in fig1 . the &# 34 ; z &# 34 ; dimension is approximately 2 to 4 millimeters and of sufficient width to allow fluids to readily flow between each of the sponge sections 13 , and also allow the sponge sections 13 to fold relative to each other . the sponge sections 13 are sufficiently spaced apart from one another so that the embodiment of the surgical floor mat 11 as shown in fig1 can be folded once as shown in fig2 and then a second time as shown in fig3 . any fluid which has been absorbed by the compressed sponge sections 13 can be trapped within the surgical floor mat 11 as shown in fig3 . the waterproof and foldable sheet 15 provides a sufficient barrier to the migration of moisture from the compressed sponge sections 13 . additionally , other flow canals 23 can be incorporated in the sponge sections 13 to provide for greater foldability , or at least partially foldability , and allow higher concentrations of fluid or moisture to migrate to drier or other parts of the compressed sponge sections 13 . these other flow canals 23 are similarly 2 to 4 millimeters in width and can be anywhere between 4 to 6 inches in length . these other canals 23 can be formed by stitching the compressed sponge sections to the foldable sheet along a 4 to 6 inch length to create an indentation . as shown in fig1 the surgical floor mat 11 is comprised of four of the compressed sponge sections 13 each having a &# 34 ; y &# 34 ; length and an &# 34 ; x &# 34 ; width . the &# 34 ; x &# 34 ; and &# 34 ; y &# 34 ; dimensions can vary for each of the compressed sponge sections 13 , as well as the number of compressed sponge sections 13 can be increased or decreased with some effect on foldability and absorption rates . as shown in fig2 adhesive strips 25 can be glued or otherwise fastened to an undersurface 27 of the foldable sheet 15 . the adhesive strips 25 may have a top peel 28 which can be easily pulled off the adhesive strip 25 to expose a sticky or adhesive surface ( not shown ) so that the surgical floor mat 11 can be more securely positioned on an operating floor . alternatively , the adhesive strips 25 may not be utilized and the peel 27 may remain intact so that the surgical floor mat 11 can be readily moved about the operating floor depending upon the particular needs of the operation . as shown in fig4 the compressed sponge sections in a dry condition have a thickness d 1 which optimumly ranges between 1 and 2 millimeters in thickness . when the compressed sponge sections are in a wet condition as shown in fig5 the thickness as shown as d 2 can be of the order of 15 to 25 millimeters , and thereby retain a substantial amount of fluid . also , the edges 17 of the sheet 15 tend to stand more erect and help retain any fluids within the compressed sponge sections 13 . the highly absorbent quality of the compressed sponge sections 13 is due to the compressed cellulose , cloth fiber and salt constituents which are formed by compressing and drying a liquefied composition of those materials so as to be compact and have a low profile in a dry condition , yet absorb a substantial amount of water for fluids when in contact with water or fluid . this type of material is known in the sponge art and typically incorporates wood pulp , cotton , flax , rayon , hemp , with polyol and sodium chloride . this composition is biodegradable and highly absorptive . for an example of its absorptive qualities , a surgical floor mat having compressed sponge sections 13 having a volume of 357 cubic inches when dry can expand to approximately 714 cubic inches when wet . in this example , the compressed sponge sections 13 can absorb approximately 6 liters of fluid , and retain that fluid in such a way as to be easily carried away and deposed of . as shown in fig4 and 5 , stippling 30 can be included on the undersurface 27 of the foldable sheet 15 . this stippling 30 provides better traction between the undersurface 27 and the foldable sheet 15 and the floor ( not shown ) during use of the surgical mat 11 during the course of an operation . such stippling 30 can be made of an elastomeric material which is silk screened onto the undersurface 27 of the foldable sheet 15 . alternatively , stippling 30 may not be necessary , provided the material used for the foldable sheet 15 is sufficiently gummy or sticky or has a coefficient of friction which would prevent the surgical floor mat 11 from slipping when placed upon the floor . it should be pointed out that the foldable sheet can be comprised of polypropylene , polyethylene , an elastomeric material or some other material which is sufficiently flexible and moisture impervious in accordance with the present invention . the optimum sizes for the embodiment of the invention according to fig1 are 24 inches by 36 inches by 2mm ranging to 12 inches by 18 inches × 9mm . also , another size is 36 inches by 36 inches by 2mm ranging to 12 inches by 36 inches by 7mm . in fig6 a second embodiment of the present invention indicated as numeral 29 is round . its radius or &# 34 ; r &# 34 ; is 24 inches in its optimum dimension for many surgical uses . many of the elements in the this embodiment except for the shape and foldability aspects of the second embodiment 29 are similar to the first embodiment as shown in fig1 - 5 . however , the additional flow canals 23 are in a locus of points about a radii from a center 31 of the surgical floor mat 29 . either prior to use when the surgical floor mat 29 is in storage or subsequent to use when the surgical floor mat 29 is to be discarded , sections 31 or 32 can be folded onto section 33 and the remaining section can be folded onto the two sections so folded . again , any absorbed moisture can be trapped sufficiently by the foldable and moisture impervious sheet 15 so as to easily transport the absorbed fluid to its disposal . finally , a third embodiment is shown in fig7 as numeral 35 . a section 37 can be folded over onto a section 39 and a section 41 can be folded onto a section 43 . then , sections 37 and 39 can be folded onto sections 41 and 43 . again , the absorbed fluid resulting from an operation can be easily and quickly transported to its disposal , minimizing leakage and allow expeditiously clean - up after surgery . for all the embodiments , the compressed sponge sections 13 can be of light blue color while the foldable sheets can be of a darker blue color or transparent or translucent so as not to be a distraction over the course of surgery in the event that operating surgeons are looking downwardly during their operation . it should be also be noted that all of the features and attributes as described for the first embodiment 11 of the invention are equally applicable to the second embodiment 29 and the third embodiment 35 of the invention . it should be appreciated that from the foregoing description that the present invention provides an improved disposal surgical floor mat which is simply to use , and simple in construction . it is easily foldable prior to its use and is easily foldable after its use to carry away surgical fluids in a sanitary manner . the surgical mat of the present invention is inexpensive to manufacture , is easily stored , is easily disposed of , and is optionally movable once positioned on the floor or can be more securely held to the floor to prevent persons in the surgery room from tripping . the surgical floor mat &# 39 ; s low profile in a dry condition further reduces the chances of accident by tripping . the surgical floor mat expanded in a wet condition allows for a substantial degree of water absorption necessary over the course of the many operations such as arthroscopic knee surgery . the surgical mat of the invention by its composition and construction resists tearing and allows a stool or chair with rollers to easily roll over the surgical mat without jeopardizing the integrity of the surgical mat . although the present invention has been described in detail with reference only to the presently preferred embodiments , it will be appreciated by those of ordinary skill in the art that various modifications can be made without departing from the invention . accordingly , the invention is limited only by the following claims .
