The male urine collection device includes a receptacle defining an internal volume, the receptacle configured to receive a penis and to collect urine, and a plurality of flaps movable to access the internal volume of the receptacle, the flaps configured to bias against the penis when the penis is at least partially received by the receptacle. In an embodiment, a male urine collection device includes a receptacle defining an internal volume, the receptacle configured to collect urine, and a clamshell having two halves movable with respect to each other via a hinge, the clamshell configured to close around the penis to secure the receptacle about the penis. The clamshell is removably secured to the penis via friction. ## Claims ### Claim 1 A male urine collection device for collection of urine discharged from a subject, the male urine collection device comprising: a receptacle defining an internal volume, the receptacle configured to receive a penis and to collect urine; an attachment interface including two attachment interface terminating ends and a plurality of flaps movable to access the internal volume of the receptacle, the attachment interface being shaped such that the two attachment interface terminating ends are positioned or positionable at least proximate to one another at a discontinuous region of the attachment interface and the attachment interface extends continuously between the two attachment interface terminating ends, the plurality of flaps configured to bias against the penis when the penis is at least partially received by the receptacle; and a clamshell having two halves movable with respect to each other via a hinge, the clamshell configured to close around the penis to secure the receptacle about the penis when the penis is at least partially received by the receptacle; wherein the clamshell includes the plurality of flaps extending from a perimeter of the clamshell and two clamshell terminating ends substantially aligned with discontinuous region and the two attachment interface terminating ends of the attachment interface, and wherein each half of the two halves of the clamshell includes an end region positioned generally opposite to the hinge, the end region of the two halves being spaced from one another with the attachment interface positioned between the end regions of the two halves. ### Claim 2 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps at least partially define an opening into the receptacle. ### Claim 3 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps are configured to bend into the internal volume of the receptacle when the penis is received. ### Claim 4 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps are positioned on a contact layer that is coupled to the receptacle. ### Claim 5 (depends on 1) The male urine collection device of claim 1, wherein the receptacle includes a wicking material therein. ### Claim 6 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps include three or more flaps. ### Claim 7 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps define a first layer of flaps that are offset from a second layer of flaps. ### Claim 8 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps are configured to constrict around the penis, when the penis is at least partially received by the receptacle, to removably secure to the flaps to the penis by elastic tension in the plurality of flaps. ### Claim 9 (depends on 1) The male urine collection device of claim 1, wherein the attachment interface defines a first gap between the two attachment interface terminating ends of the attachment interface and the clamshell defines a second gap between the two clamshell terminating ends of the clamshell and coinciding with the first gap, the first gap and the second gap configured to allow the clamshell to receive the penis. ### Claim 10 (depends on 1) The male urine collection device of claim 1, wherein the receptacle includes a sump that is configured to be in fluid communication with a vacuum. ### Claim 11 (depends on 1) The male urine collection device of claim 1, wherein the plurality of flaps form a tacky, non-adhesive interface with the penis. ### Claim 12 (depends on 1) The male urine collection device of claim 1, further comprising a pull-through strip configured to secure the receptacle around the penis via friction. ### Claim 13 A male urine collection device for collection of urine discharged from a penis, the male urine collection device comprising: a receptacle defining an internal volume, the receptacle configured to collect urine; an attachment interface including two attachment interface terminating ends and a plurality of flaps movable to access the internal volume of the receptacle, the attachment interface being shaped such that the two attachment interface terminating ends are positioned or positionable at least proximate to one another at a discontinuous region of the attachment interface and the attachment interface extends continuously between the two attachment interface terminating ends, the plurality of flaps configured to bias against the penis when the penis is at least partially received by the receptacle; and a clamshell having two halves movable with respect to each other via a hinge, the clamshell configured to close around the penis to secure the receptacle about the penis when the penis is at least partially received by the receptacle; and a pull-through strip including a first portion extending from a first half of the two halves of clamshell and a second portion extending from a second half of the two halves of the clamshell and configured to pull through the first portion to close a gap of the clamshell around the penis and/or tighten the clamshell around the penis, wherein the pull-through strip is sized and dimensioned to selectively constrict the penis to restrict urine flow from the penis; wherein the clamshell is removably secured to the penis via friction, and wherein each half of the two halves of the clamshell includes an end region positioned generally opposite to the hinge, the end region of the two halves being spaced from one another with the attachment interface positioned between the end regions of the two halves. ### Claim 14 The male urine collection device of 13, wherein the clamshell forms a tacky, non-adhesive interface with the penis. ### Claim 15 (depends on 13) The male urine collection device of claim 13, wherein the hinge is biased to keep the two halves of the clamshell together in a closed position. ### Claim 16 (depends on 13) The male urine collection device of claim 13, wherein the clamshell includes a closing mechanism to secure the two halves in a closed position. ### Claim 17 (depends on 16) The male urine collection device of claim 16, wherein the closing mechanism includes at least one of an adhesive, Velcro, or a knot.
