Foam shifts or distributor describes a kind of distribution foam of the foam from source, and the tank usually to pressurize and one can effectively remove or air and initial foam are from device to ensuring the foam of aseptic and quality when syringe is full of from device. The device includes the foam of foam phase forcommunication arrangement and source, and foam passages are in fluid communication, and has foam inlet and including foam outlet, is used to engage by injection needle The foam approach being in fluid communication with Waste outlet. Foam approach includes that tubular protrusion is arranged to extend through foam outlet and arrives injection needle, and when syringe is connected to foam outlet, a kind of can improve cleans the efficiency of technique and prevent from collecting air or foam. The device further includes a device, and for limiting material displacement by Waste outlet, allowing users to control foam volume is waste.
