A urine collection bag is provided which includes at least one sheet of flexible material defining a collapsible fluid reservoir and a support member defining a fluid channel and including a spout having an outlet opening. The support member is configured such that the longitudinal axis of the spout defines an acute angle with a horizontal axis when the fluid reservoir is empty but moves to a position wherein the longitudinal axis of the spout is substantially parallel to a vertical axis when the fluid reservoir is filled. The support member is configured to support a discharge valve such that the discharge valve is more accessible when the fluid reservoir is filled with fluid.
