US Patent 7927321 Portable sling toilet

A reliable, private and sanitary device is provided for capturing human waste in the wilderness. A small double ended bag contains a roll of toilet paper in one end and an extendable padded strap in the other. A user pulls the padded strap from the bag, loops it around a tree and around the user's body, and attaches its end to the other end of the strap after extending that end of the strap from the other end of the bag. Then the user can lean back against the padded strap, and deposit bodily waste in a collection bag. The device is light, portable, reusable, and suitable for use by hikers, rafters, and other outdoor enthusiasts in areas where human waste is carried out rather than left behind.
