Abstract

A walking aid with irritant dispenser includes a shaft having upper and lower ends and defining a hollow chamber configured to contain an irritant. A compressed air cartridge is positioned in the shaft in fluid communication with the chamber. A trigger is operatively coupled to the air cartridge and configured to cause air to be released from the cartridge into the chamber when actuated. A piston situated in the chamber is movable between an upward configuration when the trigger is not actuated and a downward configuration when the trigger is actuated. The lower end of the shaft defines an outlet in fluid communication with the chamber through which the irritant is released when the piston is at the downward configuration. The chamber includes a predetermined amount of fluid pressure such that infusion of air from the compressed air cartridge increases the pressure and urges the piston toward the downward configuration.
