Abstract: A device for subcutaneous delivery of a medicament includes a delivery module to house a cartridge containing a medicament to be delivered to a patient via a needle and a control module coupled to the delivery module to house a control unit and a battery to power the control unit. The delivery module includes an application surface that contacts the patient's body and two opposite first gripping perimeter surfaces extending along a first direction parallel to the application surface and along a second direction perpendicular to the application surface and having substantially equal dimensions in the second direction. The control module includes two opposite second gripping perimeter surfaces extending along the first direction and along the second direction and having substantially equal dimensions in the second direction. The two first gripping perimeter surfaces and the two second gripping perimeter surfaces have substantially equal dimensions in the first direction.
