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 havinga valve body having at least one passageway,a valve seating surface located on the internal receptacle, the valve seating surface configured to form a seal with the valve body in a valve closed position, andan 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, anda 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.

Abstract
The invention relates to a method and device for treating or preventing or suppressing a disease or condition in a non-human animal. The method comprises the steps of providing a single delivery device containing two components for sequential delivery from the delivery device. A first component is delivered from the single delivery device into a teat canal of a non-human animal and subsequently the second component is delivered from the single delivery device into the teat canal. The components are delivered without substantial mixing of the components.

30. 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, the internal receptacle including a distal end having an outlet, a valve for separating the first component and the second component, the valve having a valve body having at least one passageway, the at least one passageway extending substantially perpendicular to the longitudinal direction, and wherein a portion of the valve body is positioned within the outlet of the internal receptacle, a valve seating surface located on an inner surface of the internal receptacle, the valve seating surface configured to form a seal with the valve body in a valve closed position, and 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, the at least one projecting member defining a substantially cylindrical form, 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.
