摘要

The device has a container intended to contain a bolus (35) when the device is in a loading position, and an ejection device for ejecting the bolus, where activation of the ejection device causes the device to move from the loading position to a delivery position in which the bolus is partially ejected from the container. The container includes a flexible O-ring (31) intended to maintain the bolus in the loading position, and to allow the passage of the device to the delivery position upon activation of the ejection device.
