the illustration of fig1 is given to allow for visual understanding of an ostomy appliance system and is not part of the invention of the present application . fig1 is a typical example of a current , commercially available two - piece ostomy pouching system consisting of a pouch 40 , a pouch flange 42 , belt tabs 44 a and 44 b ( 44 b not shown ) on either side of the pouch flange ; a tab on the upper flange facilitates easy removal , and a fold and lock drain 48 for removal of waste . the two - piece appliance also consists of a faceplate 30 , with coupling flange 34 b and centrally located aperture 36 to receive a stoma 31 . an outer taped portion 32 aids adhesion of an appliance faceplate on the abdomen . one embodiment of the guard system 10 / 50 is shown in fig2 - 4 , and a condensed description is given below , and an in depth description given in an international application pct / us2012 / 046221 . the first embodiment of an absorbent article is specifically for use with the guard system 10 / 50 , and necessary details are given here to inform how , where , and why it is used with an ostomy appliance , the guard system &# 39 ; s approximate size and physical structure in relation to the faceplate of an appliance , and is not part of the invention of the present application . the exemplary guard system of fig2 provides a secure boundary against loss of containment of bodily waste , helps a stoma to protrude , allows flow of output , aids adhesion of an appliance faceplate , and allows one to wear form - fitted clothing among other beneficial functions . the ostomy appliance guard system illustrated in fig2 is comprised of a guard 10 and an adapter 50 . the adapter 50 is provided in various sizes in the centrally located aperture 56 to accommodate the various flange sizes of ostomy appliances currently available , and allows the guard 10 to remain a universal size . appliance flanges are provided in common sizes between appliance manufacturers , but are not necessarily interchangeable . the adapter 50 , shown already in place , illustrates that flange 42 of pouch 40 is snapped into place with complementary flange 34 b of a faceplate 30 . the adapter 50 applied first , having the pouch end 48 guided through the rear of centrally located aperture 56 , is lifted up and over the upper portion of a pouch 41 , and aperture 56 is then circumferentially surrounding the now coupled appliance flanges 42 and 34 b . adapter 50 , pressing inwardly on flange base 34 , helps a stoma to protrude while preventing the flanges 42 / 34 b from protruding into the body of the guard 10 . pouch tabs 44 a , 44 b and 46 may be removed for more efficient use of the guard system 10 / 50 . the guard 10 is applied in the same manner as adapter 50 , and pouch end 48 is guided through rear central aperture 16 b of guard 10 , then out through front aperture 16 a , the arrow indicates that guard 10 is then lifted upwards until body 14 of guard 10 encompasses the now engaged flanges including the upper pouch portion 41 ( tucked inside guard body in use to prevent intestinal gasses from ballooning above a waistline of pants ), and annular ring 12 of guard 10 and adapter 50 snap - fit together , into the adapter &# 39 ; s guard receiving channel 59 , in a mechanical interlock via adapter retaining ribs 55 enabling the guard system 10 / 50 to maintain it &# 39 ; s position proximate a stoma 31 . the body 14 of the guard 10 allows unhindered flow of output . in case liquid output behind the faceplate 30 causes the hydrocolloid adhesive member 38 to loosen from the skin , the hydrocolloid adhesive member 38 may push into a cavity formed by sloping section 57 and support wall 58 and sealed by guard receiving channel 59 that provides a temporary reservoir for effluent , allowing the user time to change the appliance before escape of output occurs . a guard system 10 / 50 contacts a faceplate 30 more or less than about ¼ in ( 0 . 06 cm ) inside the outer periphery of said faceplate . adapter protrusions 52 , on the body - facing side of an adapter 50 , create discontinuous contact on a faceplate 30 facilitating blood flow in the non - contact areas and beneficially reducing an itchiness associated with continuous pressure on the skin . referring to fig3 , the adapter 50 is shown unaccompanied by the exemplary guard 10 of fig2 , and is shown with only an adapter 50 , pointing out the close proximity of a guard system &# 39 ; s outer circumference proximate the edge of outer taped portion 32 of a faceplate 30 . a guard system aids adhesion of a faceplate preventing a sudden loss of containment , however , liquicious output is insidious and more difficult to contain than solid matter and small amounts of liquid may seep out from under the outer taped portion 32 of a faceplate 30 , soiling a wearer &# 39 ; s clothing or bed linens . leakage always comes from under a faceplate unless there is a defect in the appliance itself , for instance , a hole in a heat seal of a one - piece appliance , or the plastic connection of a floating flange ( which allows one to snap on a pouch without pressure on the abdomen ), or leakage may come from accidental uncoupling or incomplete coupling of a pouch 40 . the first embodiment will illustrate an absorbent article having a greater thickness in the absorbent core that extends beyond the periphery of a user &# 39 ; s preferred faceplate for the purpose of absorbing and blocking any liquid seepage emerging from under outer tape portion 32 of a faceplate 30 preventing embarrassing loss of containment . a continuous density throughout the absorbent core , and especially underneath the guard system 10 / 50 , would detract from a significant and intended function of said guard system , because by design , the adapter 50 has a sloping section 57 that provides a temporary reservoir for effluent in the case liquid output behind a faceplate causes the hydrocolloid member 38 to loosen from the skin . an absorbent article with optimal fluid absorbency and excellent barrier properties against wetness next to the skin would bring peace of mind to a user as well as a preventative against soiling the user &# 39 ; s clothing or bed linens . fig4 shows the arrangement of a guard system , appliance , and faceplate on a torso ( parts of the appliance and guard systems shown in phantom ), illustrating a similar embodiment of the guard 10 that includes slits 22 and a security strap 24 . a user may attach a faceplate 30 to the abdomen as shown in fig4 with corners applied diagonally , as in a diamond shape , or may adjust it a quarter of a turn so that the faceplate 30 is in the shape of a square on the abdomen , and is done so , according to the unique situation of a user , applied in one way or the other in an attempt to derive greater security in areas prone to leak or that may even be herniated . leaks usually emerge between corners of square , or generally square faceplates . fig5 illustrates the individual components of the absorbent article 110 and consists of two sides or two surfaces , a body facing side or body facing surface 111 a , and a garment facing side or garment facing surface 111 b ( not shown ), a fluid permeable top sheet 112 , a fluid impermeable backsheet 114 , and cores 120 and 121 interposed between . absorbent core 121 may be a distribution or transfer sheet , its purpose well known in the art , and may be interposed between the topsheet 112 and outer core 120 or alternately , may be a web backing layer interposed between outer core 120 and backsheet 114 , but all in accordance with the best mode of manufacture to accomplish the desired functions . alternately , cores 120 and 121 may be one sheet with varied degree of thickness . the absorbent article 110 also provides a centrally located aperture 118 through each member component of said absorbent article , for the purpose of maintaining a position upon a faceplate 30 of an ostomy appliance . not having a flat configuration , outer core 120 , has a greater radially extended absorbent core aperture 120 a , in comparison to the other member components . the fluid permeable top sheet 112 and fluid impermeable backsheet 114 extend beyond the cores 120 , 121 in at least a lateral direction and are joined to one another in the area outside said cores 120 , 121 to form an edge seam 116 ( and ) and an outer border 128 , and may be joined by gluing , crimping or heat - sealing completely around the periphery of the absorbent article , including sealing the edges of central aperture 118 , secured by any means known in the art . the outer border 128 , having a front , or body facing border 128 a , and a back , or garment facing border 128 b , ( not shown ) may be supplied in any shape or form that provides the best protection against leakage if outer border 128 is utilized for taping the absorbent article 110 to the body . the conjoined absorbent article 110 is applied in the same fashion as the guard system 10 / 50 by guiding the pouch end 48 of an ostomy pouch 40 through central aperture 118 of body facing surface 111 a of the topsheet 112 , and out garment facing surface 111 b , and lifting the article up and over the upper portion of a pouch 41 ;
