Abstract:
1. An injector device for delivery of components into the teat canal of a non-human animal comprising: a proximal end, a distal end, and a longitudinal axis defining a longitudinal direction, a barrel for containing a first component, an outlet nozzle located at a distal end of the barrel and configured for insertion into a teat canal, an internal receptacle within the barrel for containing a second component to be injected into the teat canal, a valve for separating the first component and the second component, the valve having an activator including at least one projecting member coupled to the barrel at a location adjacent the outlet nozzle and extending proximally toward the delivery member, the projecting member configured to open the valve to allow the second component to be released from the internal receptacle, and a delivery member arranged to deliver the first component from the barrel and engage the valve body into contact with the at least one projecting member of the activator to displace the valve body proximally away from the valve seating surface in order to open the at least one passageway, sequential delivery of the second component from the internal receptacle through the outlet nozzle occurring upon further depression of the delivery member, the barrel forming an outer barrel and the internal receptacle including an inner barrel located within the outer barrel, the inner barrel including a close fit within the outer barrel so as to form a plunger to be pushed through the outer barrel by the delivery member for delivery of the first component.
