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 a guide positioned on the connection member. The guide includes a platform portion and a guide portion, both of which being adapted to form a container passage. The dispenser may also include a sealed chamber mounted on the connection member. The sealed chamber has a first tip, a second tip, and a movable seal positioned within the sealed chamber. The movable seal forms a first reservoir proximate to and in fluid communication with the first tip and a second reservoir proximate to and in fluid communication with the second tip. Both of the tips are adapted to be selectively connected in fluid communication with the fluid communication channel and with an external fluid source.
