摘要

The invention concerns an injector device (1) for essentially simultaneous introduction of one or several media into or through a patient's skin (27), said device (1) comprising a carrier (2) arranged to be applied on the skin (27). The carrier (2) supports a plurality of needle means (7) intended for injection of the media, said plurality of needle means (7) arranged to be moved essentially simultaneously from a first position externally of the skin (27) to a second position in which said needle means have pierced or penetrated through the skin (27). The carrier (2) is formed with at least one membrane (10) arranged to actuate said needle means (7). The device (1) further comprises a pressure generating means (17) which is arranged to affect the membrane (10) by exerting pressure thereon to move said needle means (7) between said first and second positions.
