Fluid dispenser

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.

         21 . A fluid dispensing device comprising a reservoir with a displaceable septum and a needle is provided 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,   a fluid reservoir located within the main housing,   an injection assembly including a needle, and   a trigger mechanism;   wherein 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 a living organism.   
     
     
         22 . The fluid dispenser of  claim 21 , wherein after expulsion of the fluid through the needle, the needle lodges into a second piston-like septum, a barb ensures that the needle, upon retraction, remains lodged in the second septum as the septum stop, the septum and the needle then translate together to an opposite end of the reservoir as the needle retracts from the skin.
