ACTUATOR SYSTEM FOR SPRAYING A FORMULATION ONTO A HOST

摘要

Actuator system (12) is used to dispense a defined volume of a formulation (18) from a pressurized vial (12). The system houses the vial (12) in a receptacle (56) of a base section (54) that also includes a dispensing section (70) (e.g. a funnel) through which the formulation (18) is sprayed. The system includes a sleeve (88) that fits over at least the vial (12) and that can be pumped by the user to controllably spray the formulation (18) from the vial (12) onto the host animal (11). For instance, in a preferred mode of operation, the user places the system (10) onto the host at the desired treatment site and then pushes or pulls down on the sleeve (88). This actuates a valve mechanism (16) on the vial (12) to spray an amount of the formulation (18) through the dispensing section (70) onto the host (11).
