Abstract
An automatic medicament delivery device and corresponding method for use with a standard needle assembly and a standard vial container that contains a medicament is disclosed. A user attaches the needle assembly and the vial container to the device. The user can transfer and measure a dose from the vial container into the device. When the user presses the tip of the device against the injection site, a needle of the needle assembly is automatically injected into the user and the measured dose is delivered into the user through the needle. When the user removes the device from the injection site, the device is re-cocked for the next injection.

An automatic medicament delivery device for use with a disposable needle assembly and a vial container that contains a medicament, the device comprising:
- an injector body;
- and
- a disposable transfer system configured to enable a user to (a) attach the disposable needle assembly to the disposable transfer system and (b) attach the disposable transfer system to the injector body, the disposable transfer system including a syringe barrel, a plunger rod, and a plunger, the plunger rod and the plunger being connected to each other and translatable in the syringe barrel, the plunger rod being configured to enable the user to attach the vial container to the plunger rod;
- and
- the attached disposable transfer system and the injector body being further configured to cooperatively enable the user to (a) transfer and measure a dose of medicament from the attached vial container through the plunger rod and the plunger into the syringe barrel prior to delivery of the dose into the user and (b) when the injector body is pressed against an injection site of the user, automatically inject a needle of the attached disposable needle assembly into the user and deliver the dose from the syringe barrel into the user through the needle.
