Device for subcutaneous delivery of a medicament

A device for subcutaneous delivery of a medicament, comprising:

• an injection needle configured to receive the medicament from a cartridge through a flexible tube and to inject the medicament to a patient;
• and
• an injection needle movement mechanism configured to move the injection needle between a rest position in which the injection needle is entirely arranged within the device and an injection position in which the injection needle protrudes at least partially from the device;
• wherein the injection needle movement mechanism comprises:
• a pushing member movable from a first service position in which the injection needle is in the rest position to a second service position in which the injection needle is in the injection position;
• a first compression spring configured to exert a force on the pushing member to move the pushing member from the first service position to the second service position, the first compression spring extending along a first axis;
• a support member on which the injection needle is mounted, the support member being movable between a first operating position in which the injection needle is in the rest position and a second operating position in which the injection needle is in the injection position, the support member comprising, on an outer side surface thereof, a coupling portion coupled to the flexible tube;
• and
• a second compression spring configured to exert a force on the support member to move the support member from the second operating position to the first operating position, the second compression spring extending along a second axis that is distinct from the first axis;
• wherein the injection needle movement mechanism has a first operating configuration in which the pushing member is coupled to the support member and the force exerted by the first compression spring on the pushing member moves the pushing member from the first service position to the second service position and moves the support member from the first operating position to the second operating position loading the second compression spring and a second operating configuration in which the pushing member is decoupled from the support member and the force exerted by the second compression spring on the support member moves the support member from the second operating position to the first operating position;
• and
• wherein the pushing member is movable around the first axis from a first angular position in which the injection needle movement mechanism is in the first operating configuration to a second angular position in which the injection needle movement mechanism is in the second operating configuration.
