Been there. Done that. But thankfully for only for a couple of weeks.
Being the engineer I made some improvements to the standard system.
I put the pee bag in a 5 gallon bucket and set the bucket on the floor near me when I wanted to use the computer. I connected 2 camera straps lengthwise, put them over my shoulder and attached the other end to the bucket so it would always go with me when I stood up and walked. I could be hands free!
Finally, I got a pair of cargo pants at GoodWill for $1 and cut a hole in the thigh pocket so I could run the tubing down inside the leg and out into the bucket.
It worked great. They do have leg bags but I was not comfortable with it flopping around my calf.
What I really wanted to do was connect my pee tube to a 75 ft length of Tygon tubing that drained into my sump pump but other members of the family thought that was disgusting and threatened to “accidentally” trip over it . Sheesh!
