Abstract
A surgical kit to prepare a unit dose injection of a surgical gas. The surgical kit includes a gas pouch filled with a surgical gas, a syringe with a needle and a plunger. Optionally additional product components are included in the surgical kit depending on the surgical procedure for which the kit is prepared, such as for example a sterilizing filter, a stopcock and a suspended spike. Preferably the surgical kit may be used in ophthalmic surgical procedures to prepare a unit dose of tamponade gas to repair retinal tears.
