    Abstract: A funnel device to facilitate urination by women in an upright position includes a semi-rigid funnel rim contoured to surround the female genital region. A flexible funnel body depends from the rim and is sealed to the rim around the circumference. The funnel body has a continuous wall sloped inwardly and towards the front of the funnel body. The funnel body terminates in an orifice situated toward the front of the funnel body. A bendable, elongated disposal tube is sealably attached to the funnel orifice and is inclined downward and outward at an angle with regard to the funnel body.
