摘要

袖带设计是准确测量血压最重要的方面。首次使用先进的界面压力传感系统详细分析了织物袖口不同部件下方的压力分布。在模拟血压测量的同时,通过实验测量所选袖带和手臂模拟器的界面处的压力分布。织物是袖带的主要构造材料,并且发现袖带织物性能与袖带和手臂模拟器界面处的压力之间存在关系。还发现,由于袖带织物与手臂模拟器的不均匀接触,同一袖带不同部分下的压力分布发生变化。附在袖带织物上的便于血压测量的部件根据其尺寸和位置限制或驱动织物;它们也可能在人的手臂上造成不均匀的界面压力分布。还检查了所选择的袖带是否在模拟器的表面上施加更高或更低的平均压力,并且范围从8mmHg到25mmHg变化。这表明,由于袖带的设计不同,手臂组织内部和动脉上方的后续压力分布也会进一步变化。这项研究发现,当需要时,袖带将无法将所需的压力转移到动脉上以阻断血液流动。

An Investigation into Design of Blood Pressure Cuffs Using the Tekscan Pressure Sensing System
Cuff design is the most important aspect to work on for the accurate measurement of blood pressure. For the very first time, pressure distribution underneath different parts/components of the fabric cuffs was analysed in detail using an advanced interface pressure sensing system. The pressure distribution at the interface of the selected cuffs and an arm simulator were measured experimentally while simulating blood pressure measurement. Fabrics are the main cuff constructing material and a relationship was found between cuff fabric properties and pressure at the interface of the cuff and the arm simulator. It was also found that the pressure distribution under different parts of the same cuff varied due to the uneven contact of the cuff fabric with the arm simulator. Components attached to cuff fabric which facilitate blood pressure measurement either confine or drive fabric according to their size and placement; they may cause non-uniform interface pressure distribution on the human arm too. It was also examined whether the selected cuffs were applying higher or lower average pressure over the surface of the simulator and the range varied from 8 mmHg to 25 mmHg. This indicates that the subsequent pressure distribution inside the arm tissues and over an artery would also vary further due to the cuffs being of different designs. This study found that cuffs would be unable to transfer the required pressure over the artery to block blood flow as and when needed.
