现在,止血带在肢体手术中起着不可缺少的作用。止血带可以成为一种工具或者成为一种武器。但是由于使用不当或止血带本身的缺点常可造成不同程度的并发症。因此深入探讨影响止血带使用的各种因素,设法克服止血带的危险乃是当前十分紧迫的任务。本研究旨在探索止血带宽度与止血压的关系以及年龄、血压、肢体周径等对止血压的影响,从而为研制理想的止血器材提供必要的资料。 Tourniquet now plays an indispensable role in limb surgery. A tourniquet can become a tool or become a weapon. However, due to improper use or the shortcomings of tourniquet itself can often lead to different levels of complications. Therefore, in-depth discussion of various factors that affect the use of tourniquet, try to overcome the danger of tourniquet is a very urgent task. The purpose of this study is to explore the relationship between the tourniquet width and the blood pressure and the effects of age, blood pressure and limb circumference on the blood pressure so as to provide the necessary information for the development of ideal hemostatic equipment.
