Abstract:
1. A method for treating, preventing, or suppressing a disease or condition in a non-human animal, the method comprising the steps of: providing a single delivery device containing a first component and a second component for sequential delivery from the delivery device, the delivery device including an outer barrel and an inner barrel within the outer barrel, the outer barrel containing the first component, the inner barrel containing the second component, the delivery device further including a valve separating the first component and the second component; inserting an outlet nozzle at a distal end of the outer barrel into a teat canal of the non-human animal; pushing a plunger through the delivery device to push the inner barrel into a distal portion of the outer barrel where an inner diameter of the distal portion is smaller than an inner diameter of a proximal portion of the outer barrel, thereby delivering the first component from the delivery device through the outlet nozzle into the teat canal, the inner barrel comprising an engagement member that sealingly engages with the distal portion of the outer barrel having the inner diameter that is smaller than the inner diameter of the proximal portion of the outer barrel; and engaging an activator with the valve to open the valve, and pushing the plunger through the inner barrel along the distal portion of the outer barrel that has the inner diameter that is smaller than the inner diameter of the proximal portion of the outer barrel, to subsequently deliver the second component from the delivery device through the outlet nozzle into the teat canal.
