Where to buy an enema bag these days?

Not at Rite-Aid or any other drug store I've been to lately. All I can find are these little plastic bottles full of saline solution.

I've had the same enema bag for the last 10 years and feel lucky to have it. However, I had to loan it to a friend this morning who was in desperate need of an enema before having a medical test taken. He had purchased one of those little saline bottles but didn't know you were supposed to take the nozzle off and remove a layer of protective paper. And neither did I, since I don't use that type. So the only solution was to rush over with mine.

Now, I confess, I would like to buy a new enema bag. But where to go? Surely, they are still made and sold somewhere. Grateful for any advice. Thanks. Tweet
