    摘要： A hypodermic syringe with a selectively retractable includes an barrel having an proximal end and a distal end that defines a receiver with a shoulder. The barrel has a hollow bore therethrough and the receiver includes a plurality of inwardly projecting cams distal to the shoulder. There is an elongate plunger with a proximal end and a distal end sized to fit slidably within the bore of the barrel to define a chamber. There is a hub with a flange and a stem that has a passageway therethrough extending distally into the receiver. The stem has distal recesses disposed to engage the projecting cams so that the hub is retained with the distal end of the stem in the receiver. The syringe includes a needle mounted in the passageway in the hub with the distal point projecting distally and the fluid path communicates with the chamber. There is a clip about the elongate plunger initially allowing movement of the plunger for drawing and expelling fluid. When sufficient distal force is applied to the plunger moving and rotates the hub, the clip engages the barrel permitting only proximal movement of the plunger. The syringe includes a spring disposed about the stem compressed between the flange and the inward shoulder. When sufficient distal force is applied to the flange the hub is no longer retained. The spring urges a proximal movement into the barrel as the plunger is moved proximally.

    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.
