A fluid dispenser used to administer fixed or adjustable doses of fluids in oral, intranasal, or injectable applications. The dispenser may be used to draw off fluid from a flexible or rigid bulk container or to draw fluid from a mounted flexible or rigid container such as a sealed-end bag or bottle, or a threaded bag or bottle. The dispenser may include an automatic venting feature to assist with the smooth, easy flow of fluid during an application and to prevent contaminants from being suctioned back into the container. The fluid dispenser generally comprises: a connection member communicatively connected to a fluid source container; a body member having a dose cylinder communicatively connected to the connection member; a piston member operationally related to the dose cylinder and spring biased in an extended position; and a trigger member attached to the piston member and communicatively connected to the dose cylinder through the piston member. Squeezing the trigger member of a primed dispenser will expel a predetermined dose of fluid from the dose cylinder out through the trigger member. Releasing the trigger member will draw the predetermined dose of fluid from the container into the dose cylinder.

[ What is claimed is:] [1.] A fluid dispenser, comprising:(a) a body member having a fluid communication channel and a dose cylinder of a predetermined volume, said fluid communication channel being communicatively joined with said dose cylinder, said body member further having a storage container sized to store a plurality of unmounted needles;(b) a fluid egress conduit communicatively connected to said dose cylinder;(c) a dose valve positioned and arranged to govern fluid flow from said fluid communication channel to said dose cylinder;(d) a piston valve positioned and arranged to govern fluid flow out of said fluid egress conduit;(e) a piston member having a piston head, a distal end and a piston rod connecting said piston head to said distal end, said piston head being sealingly fit within said dose cylinder; and(f) a trigger member attached to said distal end of said piston member, said trigger member having a portion to receive a mounted needle;whereby said fluid dispenser, when primed, draws a dose of fluid through said communication channel into said dose cylinder during a complete expansion stroke of said piston member and expels said predetermined amount of fluid from said dose cylinder through said fluid egress conduit during a complete compression stroke of said piston member.
