Flo-Bak spray douche
From Woman's Personal Hygiene, by Leona W. Chalmers, published 1946. Leona is preoccupied with cleanliness of woman's bodies. "Infection in these parts may eventually affect the entire reproductive system, and undermine a woman's health. The source of a woman's vitality lies largely in her endocrine glands...the principal of which are probably the ovaries. These small organs may easily be infected by way of the vagina. Doctor Bubis, you will note, calls the vagina a POTENTIALLY INFECTED CAVITY."
These x-rays show how well the douching liquid spreads in the vagina.
Google revealed that Leona patented the menstrual cup (shown in this book) in 1937, though they didn't catch on until 60 years later.
