Abstract: The invention relates to a medicament injection device in which the material to be injected can be distributed through injection points over a large area surface, whereby simultaneously the device can be easily secured at the injection points and can lie relatively flush with the body without taking up a great deal of space. A mounting support is provided on which several cannulae are held spaced from one another, which are connected with a supply conduit and whose longitudinal axes, when the device is in a flat position, extend parallel to one another.
