The Entonox regulator. On one end of the pipe, we have a Schrader valve. The Schrader valve will only fit Entonox cylinders, it will not fit into an oxygen cylinder. It's designed that way so as we can not have any accidents. You will also notice the pipe is coloured blue and white to denote that it's an Entonox giving set. And the mouthpiece as well is also... Or the regulator's head is also colour coded blue and white, so there shouldn't be any chance of mixing it up.

The regulator head itself pivots and turns, and it has a flush button. The flush button is there to de-pressurise when you take the cylinder down, or when you take the pipe back off the cylinder. It is not to be used to administer Entonox, it is not to be used. There is a blower valve on the top, and then there is a port where the patient actually takes the Entonox on board. That port itself has a mouthpiece, they come as a sterile, sealed mouthpiece. There is a flat part that goes into the patient's mouth. The reason they are sterile is obviously 'cause the patient doesn't want to multiple-use somebody else's, so it's a one use only and throw away.

There is also then a one-way valve which stops any vapour or spit or sputum going back into the unit itself. So it's just to keep the unit clean. That coupled to the actual regulator by pushing on and the patient then inserts the mouthpiece into their own mouth and sucks. It is important when it's self-administered, it is explained as to how it works. The patient has to suck on the pipe and it will then administered gas. If you don't suck it will not administer.
