  • Patent number: 6113008
    Abstract: Actuator system is used to dispense a defined volume of a formulation from a pressurized vial. The system houses the vial in a receptacle of a base section that also includes a dispensing section (e.g., a funnel) through which the formulation is sprayed. The system includes a sleeve that fits over at least the vial and that can be pumped by the user to controllably spray the formulation from the vial onto the host animal. For instance, in a preferred mode of operation, the user places the system onto the host at the desired treatment site and then pushes or pulls down on the sleeve. This actuates a valve mechanism on the vial to spray an amount of the formulation through the dispensing section onto the host.
