- 摘要:
- <p>A unit dose, gas-filled syringe (12) is provided which is filled with a gas and packaged in a gas barrier material (10) prior to use to increase shelf-life, that is, to minimize gas leakage and dilution of the contents of the syringe. The syringe (12) is filled with a selected gas and sealed inside a container (10) made from a high gas barrier material . The container is also filled with the selected gas. The container material is selected to have a gas transmission rate sufficient to prevent the selected gas from diffusing out of the container into the atmosphere. The volume of the gas in the container is greater than the atmospheric pressure to prevent the atmospheric contaminants from entering the container and syringe.</p>
