RD equipment in the USA manufacture an Electric Leg Bag Emptier that enables anyone who can't empty their  urinal bag by themselves to do it electronically. I have been using this particular leg Bag emptier for nearly 10 years and it is probably one of the most important pieces of equipment I own.  It enables me to both live independently and drink as much fluid as I want without worrying about my bag filling and me not being able to empty it. Nobody would argue that this leg Bag emptier is quite expensive.  However, how much you put on your independence and health?  I like to drink several pints of water a day, having this leg Bag emptier means I can do just this.

 If you are going to buy one of these leg bag emptiers, have a look at the exchange rate between the US dollar and the British pound.  This will determine how much you pay for the leg bag emptier
