摘要：
A needle guard safety device (100) attachable to a drug cartridge (200) having a cylinder, a flange (210) formed at the proximal end of the cylinder, and a needle (220) coupled to the distal end of the cylinder, the needle guard safety device (100) comprising: a body (110) intended to receive a cartridge (200) of medicament and having a body seat (111), a needle guard (120) intended for covering a used needle (220) from the drug cartridge (200), a plunger (140) intended to dispense a drug from the drug cartridge (200), and a spring (130) for activating the guard (120) of needle, the spring (130) including internal turns (138) and end turns (136) at both ends, in which the needle guard (120) and the body (110) are held together by actuating fingers (121) which extend from the needle guard (120), which hooks onto the seat (111) in the body po (110), engaging the body (110) and the needle guard (120) under spring loading prior to use of the device, in which the fingers (121) actuators of the needle guard (120) are spaced such that, when the medication cartridge (200) is mounted on the needle guard safety device (100), the flange (210) of the medication cartridge will not contact the actuator fingers (121), characterized by that the spring end coils (136) at both ends are of a larger diameter compared to the internal spring coils (138) in order to reduce the likelihood that one end of the spring coil will interfere with the medicine cartridge when the medicine cartridge (200) is mounted on the needle guard protection device (100).Un dispositivo (100) de seguridad de guarda de una aguja acoplable a un cartucho (200) de medicamento que tiene un cilindro, una brida (210) formada en el extremo proximal del cilindro, y una aguja (220) acoplada al extremo distal del cilindro, comprendiendo el dispositivo (100) de seguridad de guarda de aguja: un cuerpo (110) destinado para recibir un cartucho (200) de medicamento y que tiene un asiento (111) de cuerpo, una guarda (120) de agu
