摘要：
An automatic medication injection device comprising: - an external body (1) extending along a longitudinal axis (X), - a syringe unit (6) disposed in said external body (1) and fixed to this, comprising a syringe (7) containing a medicament to be injected, a needle (7a) and axially slidable plunger means (8, 9), - means for assembling the device from a resting position to a first armed position for administering a first dose and a second armed position to administer a second dose, said assembly means being disposed at one end of said external body (1) and comprising a dose selection sleeve (15) extending within said external body (1), - first elastic means (10) disposed between said assembling means and said piston means (8, 9), said first elastic means being in a compressed state when the device is in the rest position and decomposed rhyming to push forward said plunger means (8, 9) and administering said first and said second dose one behind the other, - an internal body (12) fixed to said external body (1) and coaxial thereto, said piston means (8, 9) arranged so that they can slide inside, - guide means between said inner body (12) and said piston means (8, 9) for controlling the axial sliding movement of said means of piston (8, 9) with respect to said inner body (12), said guide means comprising first guide means (26a, 26b) formed in said inner body (12) and second guide means (11) extending from said piston means (8, 9) and that are coupled so that they can slide into said first guide means (26a, 26b), - a cursor (30) disposed at the other end of said external body (1) and limited in axially sliding with it as a result of a pressure exerted on re its free end against second elastic means (35) arranged between said cursor (30) and said external body (1) between a first position, in which the sliding movement of the cursor (30) and the cursor (30) is prevented extends from said external body (1) over the syringe needle (7a), and a second position, in which said
