a collection reservoir coupled to the distal end of the drainage conduit. ### Claim 2 (depends on 1) The fecal collection system of claim 1, wherein the user interface comprises an adhesive sheet including an adhesive on the proximal side, and wherein the adhesive sheet defines an aperture that is axially aligned with a lumen of the drainage conduit. ### Claim 3 (depends on 1) The fecal collection system of claim 1, further comprising a first one-way valve in the lumen defined by the drainage conduit, wherein the first one-way valve is configured to allow feces to flow in a direction from the proximal end to the distal end and inhibit the feces from flowing in a direction from the distal end to the proximal end. ### Claim 4 (depends on 1) The fecal collection system of claim 1, wherein the collection reservoir comprises a second one-way valve that is configured to allow feces to flow from the drainage conduit to the collection reservoir and inhibit the feces from flowing from the collection reservoir to the drainage conduit. ### Claim 5 (depends on 1) The fecal collection system of claim 1, wherein the applicator comprises a first lateral portion, a second lateral portion, and a hinge portion between the first lateral portion and the second lateral portion, and wherein the first lateral portion and the second lateral portion are configured to move about the hinge portion between an extended state and a folded state. ### Claim 6 (depends on 5) The fecal collection system of claim 5, wherein the applicator further comprises a slit extending along the hinge portion between the first lateral portion and the second lateral portion of the applicator. ### Claim 7 (depends on 6) The fecal collection system of claim 6, wherein the hinge portion comprises a first bridge portion and a second bridge portion, and wherein the first later portion and the second lateral portion are coupled to each other only at the first bridge portion and the second bridge portion. ### Claim 8 (depends on 5) The fecal collection system of claim 5, wherein the applicator comprises an alignment indicator that indicates a position of an aperture in the user interface, and wherein the alignment indicator comprises a first line that extends on the applicator from a top of the aperture to a peripheral edge of an adhesive sheet, and a second line that extends on the applicator from a bottom of the aperture to the peripheral edge of the adhesive sheet. ### Claim 9 (depends on 1) The fecal collection system of claim 1, wherein a proximal end of the drainage conduit is coupled to the user interface at a location that is offset below a center of the user interface. ### Claim 10 (depends on 1) The fecal collection system of claim 1, wherein the user interface further comprises a first release liner removably coupled to a first half of an adhesive sheet of the user interface; and a second release liner removably coupled to a second half of the adhesive sheet. ### Claim 11 (depends on 10) The fecal collection system of claim 10, wherein the first release liner comprises a first portion and a second portion, wherein the first portion of the first release liner covers the first half of the adhesive sheet, wherein the second portion of the first release liner has a first end that is coupled to the first portion of the first release liner at an inner portion of the user interface and a second end that is separate from the first portion of the first release liner at an outer portion of the user interface, wherein the second release liner comprises a first portion and a second portion, wherein the first portion of the second release liner covers the second half of the adhesive sheet, and wherein the second portion of the second release liner has a first end that is coupled to the first portion of the second release liner at an inner portion of the user interface and a second end that is separate from the first portion of the second release liner at an outer portion of the user interface. ### Claim 12 A method of using a fecal collection system, comprising: positioning a user interface assembly at an anus of a user, wherein the user interface assembly comprises a user interface and an applicator; coupling the user interface to skin of the user by using the applicator to press the user interface against the skin of the user; and after coupling the user interface to the skin of the user, removing the applicator from the user interface. ### Claim 13 (depends on 12) The method of claim 12, wherein coupling the user interface to skin of the user comprises coupling an adhesive sheet of the user interface to the skin of the user. ### Claim 14 (depends on 13) The method of claim 13, further comprising removing a first release liner from a first half of the adhesive sheet and removing a second release liner from a second half of the adhesive sheet, wherein the first release liner comprises a first portion and a second portion, wherein the first portion of the first release liner covers the first half of the adhesive sheet, wherein the second portion of the first release liner has a first end that is coupled to the first portion of the first release liner at an inner portion of the user interface and a second end that is separate from the first portion of the first release liner at an outer portion of the user interface, wherein the second release liner comprises a first portion and a second portion, wherein the first portion of the second release liner covers the second half of the adhesive sheet, wherein the second portion of the second release liner has a first end that is coupled to the first portion of the second release liner at an inner portion of the user interface and a second end that is separate from the first portion of the second release liner at an outer portion of the user interface, wherein removing the first release liner from the first half of the adhesive sheet comprises pulling the second end of the second portion of the first release liner outwardly away from the user to separate the first portion of the first release liner from the adhesive sheet, and wherein removing the second release liner from the second half of the adhesive sheet comprises pulling the second end of the second portion of the second release liner outwardly away from the user to separate the first portion of the second release liner from the adhesive sheet. ### Claim 15 (depends on 12) The method of claim 12, wherein coupling the user interface to the skin of the user by using the applicator to press the user interface against the skin of the user comprises: hingedly moving a first lateral portion of the applicator and a second lateral portion of the applicator relative to each other to press the user interface against the skin of the user. ### Claim 16 (depends on 15) The method of claim 15, wherein the applicator further comprises a slit extending along a hinge portion between the first lateral portion and the second lateral portion of the applicator. ### Claim 17 (depends on 15) The method of claim 15, wherein coupling the user interface to skin of the user by using the applicator to press the user interface against the skin of the user comprises holding the user interface and the applicator in a single hand while the user interface and the applicator are in a folded state such that the first lateral portion and the second lateral portion are folded about the hinge portion, and the user interface is positioned externally to the applicator. ### Claim 18 (depends on 15) The method of claim 15, wherein removing the applicator from the user interface comprises decoupling the first lateral portion and the second lateral portion from the user interface. ### Claim 19 (depends on 12) The method of claim 12, further comprising coupling a collection reservoir to a distal end of a drainage conduit, wherein a proximal end of the drainage conduit is coupled to a distal side of the user interface, wherein the drainage conduit defines a lumen configured to guide feces from the proximal end to the distal end. ### Claim 20 (depends on 12) The method of claim 12, wherein coupling the user interface to skin of the user by using the applicator to press the user interface against the skin of the user comprises aligning an alignment indicator on the applicator with an anus, wherein the alignment indicator indicates a position of an aperture in the user interface, and wherein the alignment indicator comprises a first line that extends on the applicator from a top of the aperture to a peripheral edge of an adhesive sheet, and a second line that extends on the applicator from a bottom of the aperture to the peripheral edge of the adhesive sheet.
