智能气压式止血带的研制

Development of intelligent pneumatic tourniquet

目的:研制一种智能气压式止血带,以减少止血带使用过程中因人为疏忽而造成的并发症。方法 :该装置的硬件设施主要由止血带部分和电子处理器部分组成。其中,电子处理器部分包括压力传感器、数据处理器、电子显示屏和报警装置。软件的信号处理设计主要采用移动平均、频域滤波算法。结果:该装置与传统止血带相比,有效地改善了患者舒适程度,提高了止血效率,降低了并发症发生几率。结论:新研制的智能气压式止血带能在保证安全性的前提下大大增加止血带使用的安全性,有效避免因人为疏忽所导致的并发症的发生,值得临床推广和使用。

Objective To develop an intelligent pneumatic tourniquet to reduce the complications due to manual operation.Methods The tourniquet was composed of two parts of tourniquet and electronic processor. The electronic processor involved in the pressure sensor, data processor, electronic display and alarm device. Moving average and frequency domain filtering algorithms were used to design signal processing. Results The tourniquet gained advantages over the traditional one in patient comfort, hemostatic efficacy and complications. Conclusion The tourniquet increases the safety while decreases the complications due to manual operation, and thus is worthy promoting clinically.
