  • the fluid impermeable barrier 106 may be air permeable and fluid impermeable thus preventing leaks while allowing air flow through the chamber 112 when a vacuum force is applied thereto (i.e., the chamber 112 remains at about atmospheric pressure thereby preventing the vacuum force from causing a hickie or kinking the conduit 142).
  • the fluid impermeable barrier 106 may be formed of a hydrophobic material that defines a plurality of pores. At least one or more portions of at least an outer surface 127 of the fluid impermeable barrier 106 may be formed from a soft and/or smooth material, thereby reducing chaffing.
  • the fluid impermeable barrier 106 is formed from polyurethane, such as formed only from polyurethane. Forming the fluid impermeable barrier 106 from polyurethane may improve the functionality of the fluid collection assembly 100. For example, the fluid impermeable barrier 106 may exhibit a flexibility when formed from polyurethane that is greater than when the fluid impermeable barrier 106 is formed from another material.

  • the smoother feel of the fluid impermeable barrier 106 formed from polyurethane makes wearing the fluid collection assembly 100 more comfortable. It has also been found that forming the fluid impermeable barrier 106 from the polyurethane allows the fluid impermeable barrier 106 to be bent (e.g., crumpled, wrinkled, etc.) more quietly than if the fluid impermeable barrier 106 was formed from another material. The improved quietness of the fluid impermeable barrier 106 allows the fluid collection assembly 100 to be used more discreetly. For example, movement of an individual using the fluid collection assembly 100 is likely to cause the fluid impermeable barrier 106 to bend.
  • the fluid impermeable barrier 106 Forming the fluid impermeable barrier 106 from polyurethane allows the individual to move more substantially without the fluid impermeable barrier 106 generating noise.

  • At least one of the first panel 108 or the second panel 110 is formed from an at least partially transparent fluid impermeable material, such as polyethylene, polypropylene, polyurethane, polycarbonate, or polyvinyl chloride. Forming at least one of the first panel 108 or the second panel 110 from an at least partially transparent fluid impermeable material allows a person (e.g., medical practitioner) to examiner the penis. In some embodiments, both the first panel 108 and the second panel 110 are formed from at least partially transparent fluid impermeable material. For example, some conventional fluid collection assemblies that include a sheath and a base may allow the sheath to be reversibly detached from the base after the base is secured to the region about the penis.
  • Detaching the sheath from the base allows the person to examine the penis.
  • configuring the sheath to be detachable from the base may allow leaks between the sheath and the base.
  • the sheath 102 may be permanently attached to the base 104, which substantially prevents leaks between the sheath 102 and the base 104 when the base 104 is appropriately attached to the sheath 102 (e.g., no wrinkles were allowed to form between the sheath 102 and base 104).
