Medical equipment catalogues from last century

Was watching tv the other evening and there was a program all about rubber medical equipment and condoms that it was possible to buy via a catalogue , this was going back to well into the last century, if not the one before that, they mentioned different condom makes and their prices, but more interestigly to me , they mentioned enema equipment and glycerin syringes , now im well aware what happens if i squirt a few ml of glycerin up my ass, were these glycerin syringes advertised, intended for the same purpose id use them for ? as ive never seen any syringes actually called glycerin syringes before, any thoughts ?
