Cardiopulmonary resuscitation (CPR) resuscitates patients suffering from cardiac arrest. Mechanical chest compression CPR highlights the need for high CPR quality to facilitate survival and neurological recovery. However, current CPR devices cannot be used on pregnant women or infants. These devices' long re-setup times interrupt CPR and can cause cerebral ischemia. This study designed a novel device with a crank-sliding mechanism. The polar coordinate system (r, θ, z) shortened the setup time and enabled adjustment without moving the patient. We compared our device with commercial products (e.g., LUCAS-2) by quantifying the compression pressure. Control groups for manual CPR of trained physicians and untrained citizens were recruited. We used Resusci Anne products as models. Our results indicated that our design exhibited performance similar to that of LUCAS-2 in adults (557.8 vs. 623.6 mmHg, p = 0.217) and met the current CPR standard guidelines. Notably, our device is applicable to pregnant women [565 vs. 564.5 (adults) mmHg, p = 0.987] and infants [570.8 vs. 564.5 (adults) mmHg, p = 0.801] without lowering the compression quality. The overall compression quality and stability of mechanical chest compression CPR were favorable to those of manual CPR. Our device provides an innovative prototype for the next generation of CPR facilities.
心肺复苏术（CPR）可使心脏骤停的患者复苏。机械胸外按压 CPR 强调需要高质量的 CPR，以促进生存和神经恢复。然而，目前的 CPR 设备不能用于孕妇或婴儿。这些设备的长重置时间会中断 CPR，并可能导致脑缺血。本研究设计了一种带有曲柄滑动机构的新型设备。极坐标系（r、θ、z）缩短了设置时间，并可在不移动患者的情况下进行调整。我们通过量化压缩压力来比较我们的设备与商业产品（例如 LUCAS-2）。我们招募了接受过培训的医生和未受过培训的公民进行手动 CPR 的对照组。我们使用 Resusci Anne 产品作为模型。我们的结果表明，我们的设计在成人中的表现与 LUCAS-2 相似（557.8 与 623.6mmHg，p=0.217），并且符合当前的 CPR 标准指南。值得注意的是，我们的设备适用于孕妇[565 与 564.5（成人）mmHg，p=0.987]和婴儿[570.8 与 564.5（成人）mmHg，p=0.801]，而不会降低压缩质量。机械胸外按压 CPR 的整体压缩质量和稳定性均优于手动 CPR。我们的设备为下一代 CPR 设备提供了创新原型。
