采静脉血标本和静脉置管是医院最为常见的介入性操作。可重复使用的止血带则是这些操作时静脉止血的常用物品。这种止血带被携带往来于病人和病室之间，实际上违背了感染控制的基本原则。作者研究的目的旨在确定可重复使用的止血带是否有为病原体的污染物，是否有造成交叉感染?
Venous blood samples and venous catheterization is the most common intervention in the hospital. Reusable tourniquets are commonly used items for venous hemostasis during these procedures. This tourniquet is carried between the patient and the ward, in fact violating the basic principles of infection control. The purpose of the authors’ study was to determine whether reusable tourniquets are contaminants for pathogens and whether they cause cross-infection.
