Abstract
Abstract A female external urine collection device has a moulded plastics tray that supports an insert or a planar top with an upper surface that contacts the wearer. The upper surface is shaped with an annular wall that engages around the vulva and an opening with a urine-resistant surface within the wall. The opening communicates with an outlet orifice in the tray so that discharge of urine is contained within the wall and flows to the outlet. A longitudinal ridge extends posteriorly of the wall and is located between the buttocks of the user.
