ABSTRACT:
The assembly includes an injection device which includes a housing having an ampule-receiving chamber, a gas charge, and means for delivering a predetermined amount of gas to the ampule-receiving chamber. The device includes an injection-counting ring which is received in a groove extending about the housing wherein the ring includes a counting mechanism thereon and is constructed to allow one-way only rotation thereof relative to the housing. The patient-fillable ampule of the invention includes an ampule body having a plunger end and an orifice end, a medication retaining cavity and an elongate plunger which is received in one end of the cavity. An orifice-bearing end cap is fixed to the orifice end of the body. A truncated hypodermic needle is received in the end cap. A removable needle is provided for filling the ampule and allows use of the ampule as a conventional syringe. The ampule is attached to the hypodermic device by means of an ampule sleeve which extends about the ampule body along the length thereof and which cooperates with a retainer collar located on the device.
