1.1 本指南为此处指定为辅助颈椎固定装置（ACSID）的装置制定了最低标准；头部横向稳定器就是此类装置的一个示例。ACSID设计用于协助急救医疗服务人员固定颈椎。 1.2 本指南不确定通过在患者身上放置ACSID实现的特定运动限制程度。医学文献中尚未确定脊柱固定的明确要求，尤其是与ACSID使用相关的限制程度。 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ACSID应具备的特性。 4.2 预计ACSID不会单独用于提供所需固定的整个范围。临床情况可能需要不同的设备组合以实现充分的全脊柱固定。ACSID可以是其中一个设备。 4.3 ACSID旨在在一个或多个运动平面中提供稳定和/或支持，以及其他固定装置 3.2.1 （参见 4.2 ).

1.1 This guide establishes minimum standards for devices designated here as adjunct cervical spine immobilization device (ACSID); a lateral stabilizer for the head is an example of this type of device. The ACSID is designed to be used to assist in the immobilization of the cervical spine, by emergency medical services personnel. 1.2 This guide does not identify specific degrees of limitation of motion achieved by placement of an ACSID on a patient. Definitive requirements for immobilization of the spine, and, in particular, the degree of limitation associated with the use of an ACSID, 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 ACSID shall possess. 4.2 It is not expected that the ACSID will be used alone to provide the entire scope of required immobilization. Clinical situations may require differing combinations of devices for adequate total spinal immobilization. An ACSID may be one of the devices. 4.3 An ACSID is intended to provide stabilization and/or support in addition to other immobilization devices in one or more of the planes of motion mentioned in 3.2.1 (see 4.2 ).
