ABSTRACT:
An injection device comprises: a needle support; an injection needle which is fixedly joined to the needle support and which has a free end which is arranged with spacing from the needle support; and a mechanism for extracting the injection needle, comprising a base and a pushing member which can be moved relative to the base between a position in which the needle is used and a position in which the needle is extracted. The base is permanently connected to the needle support and can be moved relative to the needle support between an inactive position of the extraction mechanism and an active position of the extraction mechanism.
