摘要:
A foam transfer or dispensing device is described which dispenses foam from a source of foam, typically a pressurised canister, and which enables efficient purging or air and an initial volume of foam from the device to ensure foam sterility and quality when a syringe is filled from the device. 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 engagement by a syringe nozzle and a waste outlet in fluid communication with the foam pathway. The foam pathway 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 pooling 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.
