| titleOfInvention | Medical delivery device with oxygen permeation inhibition |
| abstract | The present disclosure relates to medical devices, such as syringes, auto-injectors, and pens, that inhibit the penetration of oxygen into fluid chambers. The medical device includes a lubricant-free (eg, silicone) or siliconized barrel having an interior surface defining a fluid chamber, an elastomeric stopper, and a plunger rod. In one embodiment, at least a portion of the inner surface of the barrel is reduced to increase the interference fit between the stopper and the barrel. In another embodiment, the stopper may include a plurality of ribs, and the valley between each pair of ribs may include a ring member disposed in each valley. The ring member includes oxygen absorbing material, oxygen absorbing material, or both, to bind any oxygen that permeates the syringe, autoinjector, or pen. In yet another embodiment, the stopper may include a barrier coating that includes an oxygen barrier material to inhibit or prevent oxygen permeation. |
