Abstract
A biological liquid collection device designed to draw blood using an 'atmospheric-balanced vacuum' to ensure the blood is exposed to the sample atmospheric partial pressure oxygen and partial pressure carbon dioxide levels as found in standard arterial blood gas syringes, resulting in blood gas sample stabilization during collection and a superior vacuum shelf-life by reducing the gas permeation rate through the plastic tube. The biological liquid collection device comprises a collection module for receiving a biological liquid sample, an evacuated container having an open end and a closed end wherein the evacuated container contains the collection module therein, and a closure for closing the open end of the evacuated container. The evacuated container comprises a gas composition that is substantially equal to the gas composition of the atmosphere outside of the evacuated container. A method for forming the atmospherically balanced vacuum collection device is also provided.
