- the guide rod 88 is provided with four axial ribs 92 distributed circumferentially. These axial ribs 92 cooperate with inner locking surfaces 94 forming contours of the axial hole 90 of the piston rod 26 so as to prevent any rotation of the piston rod 26 with respect to the positioning control member 34.
- the guide rod may also have a square, triangular, rectangular or any other suitable shape, or have one or more reliefs other than axial ribs and preventing its rotation relative to the control member.
- the user grasps the outer casing 66 and applies the distal surface 44 of the end sleeve 42 against the skin of the patient and then exerts a brief support of the automatic injection device 16 against the skin of the patient so as to slide the positioning control member 34 into the outer housing 66.
- the ramps 84 of the flexible tabs 74 cooperate with the retraction members 80 of the outer casing 66 and move to their retracted configuration (see FIG. 12).
- the positioning control member 34 When the positioning control member 34 reaches its activation position of the automatic injection device 16, the first and second complementary immobilization stops 70, 72 no longer cooperate and the piston control member 30 is free to moving axially relative to the positioning control member 34. Then, under the action of the injection spring 60, the piston control member 30 moves toward the distal end of the positioning control member 34.
- the needle control member 32 is driven by the piston control member 34 and pushes the syringe holder 28 and the injection syringe 18 so that the injection needle 22 is inserted into the skin of the patient.
- the syringe holder 28 and the needle control member 32 move from their engaged configuration to their release configuration.
- the needle control member 32 and the piston control member 30 can then continue their axial movement toward the distal end of the positioning control member 34 without causing the syringe holder 28.
- piston control 30, which is still engaged with the piston rod 26, pushes the piston rod 26 and the piston towards the distal end of the automatic injection device 16. In this way, the pharmaceutical liquid contained in the syringe injection 18 is injected.
- the piston control member 30 and the piston rod 26 move from their engaged configuration to their release configuration.
- the piston rod 26, the injection syringe 18 and the syringe holder 28 are free to move axially toward the proximal end of the positioning control member 34.
- Reminder means known to man of the craft push the injection syringe 18 toward the proximal end of the positioning control member 34 so that the injection needle 22 retracts.
- the releasable coupling means 54, 56 are permanently positioned axially between two axial ends of the spring.
- the axial size of the various organs of the automatic injection device 16 between them is optimized and the automatic injection device 16 has a reduced length.
- the axial size of the coupling means 54, 56 of the piston control member 30 and the piston rod 26 has no effect on the axial dimension of the automatic injection device 16.
- the invention is not limited to the embodiment shown and other embodiments will become apparent to those skilled in the art. It is in particular possible to modify the configuration of the cam paths of the control member so as to reduce their axial size.
