Abstract: The existing syringes in use today consist of a single barrel with only one chamber and one plunger. The “Single Barrel Double Chamber Syringe” is a modified version of the existing syringe in that it uses a single barrel syringe separated into two chambers by the use of a hollow cone shaped floating plunger. The hollow floating plunger creates two independent chambers capable of delivering two medications in one motion without mixing of the fluids. The hub of the syringe has also been modified with a needle that has a sharp point facing to the inside of the syringe and has a small hole bored into the side near the base. This will allow the hollow floating plunger to be pierced once the first chamber is emptied. The hole in the base of the needle will relieve the pressure in the first chamber after the needle has passed through the hollow floating plunger while allowing any remaining fluid to be expelled.
