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（CPR）使患有心脏骤停的患者复苏。机械式胸外按压心肺复苏术强调需要高心肺复苏术以促进生存和神经恢复。但是，当前的CPR设备不能用于孕妇或婴儿。这些设备的重新设置时间长，会中断CPR，并可能导致脑缺血。这项研究设计了一种具有曲柄滑动机构的新型装置。极坐标系（r，θ，z）缩短了设置时间，并且可以在不移动患者的情况下进行调节。通过量化压缩压力，我们将设备与商业产品（例如LUCAS-2）进行了比较。招募了经过培训的医生和未经培训的公民进行人工心肺复苏术的对照组。我们使用Resusci Anne产品作为模型。p  = 0.217）并符合当前的CPR标准指南。值得注意的是，我们的设备适用于孕妇[565 vs. 564.5（成人）mmHg，p  = 0.987]和婴儿[570.8 vs. 564.5（成人）mmHg，p  = 0.801]，而不会降低压缩质量。机械式胸部按压CPR的整体按压质量和稳定性优于手动CPR。我们的设备为下一代CPR设备提供了创新的原型。
