摘要： A medication cartridge for use with a medication delivery pen having a cartridge body with threads at its distal end for receiving a pen-needle. The threads are either integrally molded in the cartridge or on the outer surface of a cap used to retain a septum on the distal end of the cartridge body. The cartridge body of the medication cartridge also includes threads or a snap-ring at its proximal end for attaching the medication cartridge directly to a pen body housing of the medication delivery pen without the need for a medication cartridge holder.

摘要： An operable syringe assembly comprises a barrel including a cylindrical coextruded body portion having a longitudinal axis. The body portion forms a side wall spaced from the axis defining a chamber for retaining fluid. The body portion includes an open proximal end and a distal end and further includes an inner portion of plastic material and a rigid portion of plastic material surrounding the inner portion. The rigid portion has a higher hardness than the inner portion. A plunger including an elongate shaft portion having a proximal end, a distal end and a rigid piston at the distal end is provided. The piston has an outside diameter greater than the inside diameter of the inner portion and a higher hardness than the inner portion. The piston portion is slidably positioned in fluid-tight engagement inside the barrel. The fluid-tight engagement is caused by the piston compressing the inner portion of the plastic material of the coextruded body portion. The proximal end of the plunger extends outwardly from the open proximal end of the barrel to facilitate moving the piston portion with respect to the barrel.
