The device comprises a foam inlet arranged forcommunication with a source of foam, a foam pathway in fluid communication with the foam inlet and comprising a foam outlet, arranged for en- gagement by a syringe nozzle; and a waste outlet in fluid communication with the foam pathway. The foam path- way comprises a tubular projection arranged to extend through the foam outlet and into a syringe nozzle when a syringe is connected to the foam outlet, which improves the efficiency of the purging process and prevents pool- ing of air or foam. The device further comprises a means for restricting displacement of material through the waste outlet, so that the user can control the volume of foam that is wasted. 111111111111110111011111111111010111110111010111111111101110111011111111111110111111 WO 2017/145132 Al 1#11101MO1101DION010130101#101101111010EMEHOE# — before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h))
