ABSTRACT:
A medicament dispensing unit having a cylindrical barrel closed at one end by a slidable plunger is provided at the other end with a diaphragm assembly including a flexible wall defining a medicament chamber between the plunger and flexible wall. A needle is positioned in spaced relation to the flexible wall whereby movement of the plunger will cause the medicament to flex the flexible wall toward the needle which will then pierce the wall to establish fluid communication between the medicament chamber and the area at the other end of the needle. A finger grip is located on the plunger end of the barrel while a nose cap assembly is affixed to the diaphragm end of the barrel.
