TubeNet

I am looking for an accessory that I used to have, but seemed to have lost...

It is a plastic cylinder about 4 inches long. It had a cap on one end and it contained a ping-pong ball. The other end had two or three different wholes, one of which you attached a tube. The object was to inhale the ping-pong ball up, and exhale in a way to maintain the ping-pong ball at the top of the tube. I don't think is is from a medical supply store, but I think it might have been inspired by those types of apparatus.

Does anybody know what I'm talking about? If so, do you know where I can get another one?

Thanks.

There ya go!

Talk to a doctor, they're quite common in Respiratory Therapy offices. Maybe you can get your health insurance to pay for it...

Thanks. Found it.
