Abstract

A fluid dispensing device is provided for dispensing a measured amount of fluid into a living organism. The device includes a rigid fluid reservoir closed by a septum for use in a fluid dispensing device for dispensing a measured amount of fluid into a living organism, wherein the device has a main housing enclosing the operative components of the device, the said fluid reservoir located within the main housing, an injection assembly including a needle, and a trigger mechanism. The needle has a first end adapted to piercing the septum and pushing the septum into the reservoir so that the septum acts as a piston, expelling the fluid through the needle, and a second end adapted to injecting the fluid into the living organism.
