The bulb syringe enema was what I also remember getting as a child.
It was used on us, and my cousin, as needed.
Aunt was an old school nurse. Who believed in the enema instead of giving OTC junk or laxatives.
Like Valerie, I have also taken the bulb syringe enema since leaving home.
It does take multiple insertions and refilling the syringe to receive a two quart enema with the 8 oz syringe.
One benefit of the enema bulb it is easy to take along when traveling. Instead of the bulky bag. With hose and nozzles.
I did find the bulb to be helpful when one of mine needed an enema when traveling or visiting a friend for a few weeks.
Always clean the syringe very well before and after use. Air
Air out for few days.
