摘要： A medical injection system (1, 100) comprising:
(a) a syringe (10) provided with:
(i) a barrel (11);
(ii) a stopper (12) and
(iii) an injection needle (13, 113);
(b) a plunger rod (63, 163) in pushing engagement with the stopper (12),
(c) an injection lock (50, 150) so as to prevent a relative movement of the plunger rod (63, 163) with respect to the barrel (11); and
(d) a needle guard (20, 120) comprising a trigger portion, and configured in sliding engagement with respect to the barrel (11) so as to define a first position covering the injection needle (13, 113) and a second position not covering a predetermined portion of the injection needle (13, 113);
wherein the trigger portion is adapted to disengage the injection lock (50, 150) from the plunger rod (63, 163) when the needle guard (20, 120) moves from the first position to the second position.-

摘要： The safety device (1) includes a tubular body (3) extending along a longitudinal axis (A), the tubular body (3) being configured to receive the medical container (2), a needle cover (4) movable relative to said body (3) between a retracted position, and an extended position in which the needle cover (4) distally extends from the retracted position in order to shield the injection needle (23) after activation of the safety device (1), a release element (6) configured to move the needle cover (4) from the retracted to the extended position after activation of the safety device (1), and a retainer (5) for maintaining the release element (6) in a compressed condition when the needle cover (4) is in the retracted position, the retainer (5) being configured to transmit a user's activation force to the needle cover (4) once the injection operation is completed. The needle cover (4) includes a distal abutment surface (46), said distal abutment surface (46) abutting against a proximal abutment surface (354) of a bump (35) protruding from the body (3) in the retracted position of the needle cover (4). The bump (35) of the body (3) has a first end (350) provided with a chamfer (355) extending in a circumferential direction.

摘要： This autoinjector (1) includes a housing (2) extending along longitudinal axis A and having an opened distal end (22), said housing (2) being configured to receive a medical container (100) having a barrel (101) defining a reservoir for containing a medical product, said barrel (101) having a distal end (102) provided with an injection needle (103). A needle cover (4) is coupled to and axially movable with respect to said housing (2) between a first extended position, a retracted position, and a second extended position. A a cap (5) is removably attached to the opened distal end (22) of the housing (2). A retainer (3) is coupled to the housing (2) for blocking a proximal movement of the needle cover (4) from the first extended position to the retracted position as long as the cap (5) is attached to the housing (2). The retainer (3) includes a distal abutment surface (30) which is radially movable between a blocking position in which said distal abutment surface (30) abuts against a proximal abutment surface (43) of the needle cover (4), and a release position in which said distal abutment surface (30) is radially shifted away from the proximal abutment surface (43) of the needle cover (4). The cap (5) includes a locking tab (6) radially abutting against the retainer (3) for maintaining the distal abutment surface (30) of the retainer (3) in the blocking position.

摘要： The cap (5) includes a housing (50) extending along a longitudinal axis A, the housing (50) having a distal end (51) and an opposite proximal end configured to be removably attached to the body (20) of the autoinjector (1). A retainer (8) is arranged inside the housing (50) and is axially movable with respect to said housing (50), the retainer (8) including an inner cavity (52) for receiving the needle shield (6), a clamping member (81) configured to remove the needle shield (6) from the medical container (4), an opened distal end (84) configured to provide access to a distal end (61) of the needle shield (6), and a proximal abutment surface (87) configured to abut against the medical container (4). A plug (9) is arranged at the distal end (51) of the housing (50), the plug (9) including a sealing portion (90) configured for closing the distal end (51) of the housing (50) and at least one anti-rattling member (91) arranged at a proximal side (901) of the sealing portion (90) for abutting against the retainer (8) and move the retainer (8) in the proximal direction.

摘要： The autoinjector (1) includes a housing (2) extending along longitudinal axis (A) and configured to receive a medical container (100) having a barrel (102) defining a reservoir for containing a medical product, said barrel (102) having a distal end provided with an injection needle and an opened proximal end (103). A power pack (6) is arranged inside the housing (2) for expelling the medical product from the medical container (100). The power pack (6) includes a plunger rod (5) configured to extend through the opened proximal end (103) of the barrel (102) for pushing a stopper (105) arranged inside the barrel (102). The plunger rod (5) is axially movable between an initial position and an injection end position distally located with respect to the initial position. Resilient adjustment means are arranged between the plunger rod (5) and the barrel (102) for compensating clearances between the plunger rod (5) and the barrel (102).
