The classic is the Bulbsyringe, the bag was for a long time not known in Europe,
Europe had some other ingenous devices (mostly french) like the "Equisere" irrigator or the "Clysopomp" (a small pewter pump in a metalbox with a lid, one filled the box with water). The bag was obviously a invention of the american rubber industry, foremost Mr. Goodyear. It was their marketing wich brought the bag into every house, (foremost the Mail-order houses like Sears had them, up to 4 qts.)
Drugstores had a separate section with all those beautyfull gadgets on display. Mothers where thankfull for it, than now they had their vaginal syringe for themselves. Since these where the earlier ways of birthcontrol. (some experts had their doubt and claimed, the sperm was just better distributed in the vagina)
In Europe the ballsyringe was also firstly used for vaginal irrigation and only secondly for enemas, the large nozzle was for this use and a smaler one could be substituted for rectal use. (You can imagine the consequence if the syringe is used for enema and another time for vaginal cleaning, lots of work for the gynodocs)
These bulbs where mostly stored in a place hitten from everybody, but as kids are, they find everything and wonder about it???
That my grandmother had one, i experienced only as i was sick and she appeared at my bedside with it (aged 6years). only very much later i remembered than i was hooked on every drugstore display with rubber health supply and the color red.
