Summary "Automatic Mixing and Actuating Devices, Automatic Mixing Syringe and Methods of Mounting a Syringe and Operating a Syringe" The present invention relates to an automatic mixing device (200), an actuating device (100). ) having an integrated plunger (130) and configured to be removably mounted to the automatic mixing device (200), and a retractable syringe (10) having the automatic mixing device (200). actuating device (100) has an initially compressed spring (150) and a trigger member (120) that is pivotable to initiate spring decompression (150) to activate the pressing of a bearing plunger (140) against a seal (250) of the automatic mixing device (200). another seal (260) also located in an outer chamber (240) of the mixing device (200) is capable of axial movement by pressing the mixing piston (140) from a first position in sealing engagement with one or more vents (211a, b) in an inner drum (211a, b) to a second intermediate position and vents (271, a, b, c, d) in an outer drum (220). This allows pressing of the mixing plunger (140) to induce a first substance from the outer chamber (240) through the openings (211a, b) for mixing with a second substance in an inner chamber (230) of the inner drum (210). ). The mixed substance in the inner chamber (230) is then delivered by the syringe (10) with subsequent needle retraction (310).resumo “dispositivos de atuação e de mistura automática, seringa de mistura automática e métodos de montagem de uma seringa e de operação de uma seringa” a presente invenção refere-se a um dispositivo de mistura automática (200), um dispositivo de atuação (100) que tem um êmbolo integrado (130) e configurado para ser montado de maneira removível no dispositivo de mistura automática (200), e uma seringa retrátil (10) que tem o dispositivo de mistura automática (200). o dispositivo de atuação (100) tem uma mola inicialmente comprimida (150) e um membro de gatilho (120) que é girável para iniciar a descompressão de mola (150) para
