Emergency CO2 source adaptor

We have invented and tested a very simple adaptor for people who want to get rid of BIG MEDICAL CO2 TANKS. It allows you to connect a small CO2 cartridge onto a classical pressure regulator as if it is a normal CO2 tannk.  This tool is portable. It is a nice idea to keep working with patient when you tank is empty. It is also a good way to stop pay monthly fee for medical gas. See photos here >
