Described herein is a device, comprising a base and a positioning member, for preventing or reducing the severity of external hemorrhoids in a patient during childbirth. The base has a first longitudinal axis and a surface extending from a first side of the base in a first direction corresponding to a height of the surface, which has a second longitudinal axis with a constant angular orientation relative to the first longitudinal axis, is of a size greater than the anal orifice, is anatomically configured to contact only the perianal region and to not substantially enter the anal canal or substantially interfere with the birthing canal. The positioning member extends from a second side of the base in a second direction away from the first side, and includes a substantially rigid structure configured for gripping by a user to position and hold the device against the anal orifice.
