A cardio-pulmonary compression device includes a motor (11) having a rotating portion, and a ball nut (12) mounted on the rotating portion and configured to rotate with the rotating portion. A ball screw (13) is received in the ball nut such that rotation on the ball nut advances and/or retracts the ball screw in accordance with a direction of the motor. A pad assembly (15) is coupled to an end portion of the ball screw such that longitudinal motion of the ball screw imparts a compression cycle to a patient. 种心肺按压装置，包括具有旋转部的电机(11)以及安装在所述旋转部上并被配置成随着所述旋转部旋转的滚珠螺母(12)。滚珠丝杠(13)容纳在所述滚珠螺母中，使得滚珠螺母上的旋转根据所述电机的方向推进和/或缩回所述滚珠丝杠。衬垫组件(15)联接到所述滚珠丝杠的端部，使得所述滚珠丝杠的纵向运动向患者施加按压循环。
