Abstract
A medication infusion device includes a pre-filled medication container containing sterile liquid medication. The medication infusion device also includes an infusion needle and the infusion needle has a distal end, wherein the distal end of the infusion needle is movable relative to the pre-filled medication container. There is a pierceable elastomeric component arranged at the distal end of the infusion needle to define a sterile environment, and this sterile environment is shared by the pre-filled medication container and the distal end of the infusion needle. The distal end of the infusion needle is embedded in a pierceable elastomeric component in order to keep the infusion needle enclosed in the sterile environment and prevent medication from flowing out of the infusion needle.
