US 70865 Improvement in menstrual receiver A 1867 patent describes a sack fitting partly or wholly inside the vagina, suspended from a ring around the cervix, but with the ring held up by a U-shaped wire, which is fastened to the sack at one end and to a belt at the other. Quote:"I construct my menstrual receiver by forming a cup-shaped ring, a, made of rubber, gum, gold, silver, or any suitable substance, which may be made round, or elliptical, or of any shape to fit the os uteri. Around the lower orifice of ring is attached a sack or bag, b, made of rubber or any suitable materials. The ring a rests-around the os uteri, and the bag b rests entirely in the vagina, or may be made of such length as to rest parily outside and partly inside. I insert a small sponge in bag b to absorb the menstrual flux."
