Abstract
A feminine napkin assembly including a menstrual pad coupled with a fluid guide that directs the flow of menstrual fluid to a desired location on the pad is provided. The fluid guide may include an elongate member with a proximal end coupled to an upper surface on the menstrual pad and a distal end extending forward towards the front end of the menstrual pad. The distal end of the elongate member may be placed against or inside the user's vagina. In this way, the fluid guide member may guide menstrual fluid to the desired location on the pad, thereby minimizing leakage of the fluid out the sides, rear, or front of the pad.
