1.1 本指南涵盖了设备的最低标准，此处指定为肢体夹板，通常称为夹板。肢体夹板用于紧急医疗服务人员固定肢体。 1.2 本指南不确定通过在患者身上放置解脱装置（ED）实现的特定运动限制程度。在医院外环境中固定四肢的明确要求，特别是在医院外环境中使用ED的限制程度，尚未在医学文献中确定。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 4.1 本指南旨在确定ES应具备的特征。 4.2 不同的临床情况可能需要不同的设备组合来充分固定肢体，包括牵引或气动设备，或两者兼有。 4.3 用于成年患者的设备应适合第95百分位成年美国男性。 4.4 标记为拟用于儿科的设备不得用于容纳成年患者。

1.1 This guide covers minimum standards for devices, designated here as extremity splint(s) (ES), commonly known as splints. Extremity splints are designed to be used for the immobilization of an extremity by emergency medical service personnel. 1.2 This guide does not identify specific degrees of limitation of motion achieved by placement of a extrication device (ED) on a patient. Definitive requirements for immobilization of extremities in the out of hospital environment, and, in particular, the degree of limitation associated with the use of an ED in the out of hospital setting, have not been established in the medical literature. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 4.1 The intent of this guide is to identify characteristics that an ES should possess. 4.2 Varied clinical situations may require differing combinations of devices for adequate extremity immobilization, including traction or pneumatic devices, or both. 4.3 A device intended for use with adult patients shall accommodate the 95th percentile adult American male. 4.4 Devices that are labeled as intended for pediatric use shall not be required to accommodate adult patients.
