Vaccine strip release system for oral immunisation of foxes against rabies using aircraft

摘要

The system has a foil tube magazine as the vaccine storage device and a main motor which drives a drum which coils the already emptied sections of the magazine (30), where the individual vaccine holders (29) are fed to the ejection point. A tongue (11) enters between the vaccine holder and magazine, a yoke (13) presses the holder under the tongue, a sprung base (7,8) clamps the holder and prevents unwanted ejection in the stationary state. A divided oblique plane (9) lifts the upper half of the foil and a rotating blade (10) penetrates into the gap and separates the foil tube magazine immediately before the ejection point. The forward motion opens the magazine and releases the vaccine holder, which stops the forward motion via a switch (2,3,4) as it falls.
