Title: Fluid dispenser apparatus

Abstract: 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 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. 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 dispenser may also include a dispensing mechanism for dispensing measured doses, a protective cap, insulation and padding.
