ABSTRACT:
A medical device includes a hollow needle having a distal end and a proximal end, and a substantially flexible storage chamber for storing a medical preparation. The storage chamber is disposed spaced apart from the proximal end of the needle. The medical device further includes a needle shield, a mechanism operable to advance the storage chamber toward the proximal end of the needle and enabling fluid communication thereof with the medical preparation in the storage chamber, and a mechanism operable to decommission the needle substantially immediately using the needle shield after injecting the medical preparation with the needle.
