If you're frugal (cheap) like me

With the closure of the LHS (20+ miles), the nearest shop is near 100 miles distant, consequently I'm always on the lookout for substitute parts or on the interweb shopping. I recently took a friend for cataract surgery and when he returned to the prep station, he was wearing an oxygen cannula (not needed, just policy). On leaving, I asked the nurse if I could have the cannula and associated tubing.

This morning, I had pulled a black widow apart, suspecting the pickup tube had come loose -- it was small diameter silicone tubing and had popped off. Remembering (more and more difficult now) the oxygen tubing, I tried it. It took some effort to get it on and even more effort to pull it off. The cannula tubing is clear; the longer tubing that ran to a wall valve was translucent green with two tubes of different diameter. The smaller diameter tubing also fit well and tightly. Both were quite flexible and would bend without kinking.

I don't know how it will hold up over time, but it can't be any worse that the original tubing that Leroy used. Either way, if it stays put for a season, I'm good with it, it was free and I have a lifetime supply.

While not wishing any of you or your friends ill, you might nab some if the opportunity arises.
