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.

Claims

1. An automatic medicament delivery device for use with a needle assembly and a vial container that contains a medicament, the device comprising:

a disposable transfer system configured to enable a user to attach the vial container to the disposable transfer system; and

an injector body configured to enable the user to attach the disposable transfer system with the vial container attached thereto to the injector body and to attach the needle assembly to the disposable transfer system after the disposable transfer system is attached to the injector body;

the disposable transfer system and the injector body being further configured to cooperatively enable the user to transfer and measure the dose from the vial container into the disposable transfer system after the disposable transfer system is attached to the injector body and to automatically inject a needle of the needle assembly into the user and deliver the measured dose from the disposable transfer system to the user through the needle after the needle assembly is attached to the disposable transfer system and when the injector body is pressed against an injection site of the user.
