Objectives. Considering the advantages of the wearable systems (such as continuous monitoring, ease of installation, and significant efficiency), they can also be used to monitor patients in emergency situations and, particularly, in the ambulance. This study is aimed at specifying, modeling, and evaluating a wearable smart blanket system for monitoring vital signs in emergency circumstances. Method. At first, all the smart blanket system requirements were specified using an author-made questionnaire, and the essential requirements were specified in the software requirements specification format. Such an anticipated smart wearable blanket is then modeled by Unified Modeling Language. Finally, the most important quality attributes (i.e., the nonfunctional requirements) of the proposed wearable smart blanket system were evaluated using a descriptive-analytical study. Results. Evaluation results of the proposed system show that using the smart blanket system could not only provide the required functionalities, but also, it improved the important quality attributes such as response time and delay in sending data packets (14% improvement), accuracy, energy consumption (18% improvement), reliability and fault-tolerance, and performance (28% improvement) in contrast to the compared related work. Conclusion. Using a smart wearable blanket in an ambulance instead of such in a huge ambulance cabin would be beneficial in terms of time and space, ease of use, and maybe cost while providing the required functionalities besides having proper quality attributes.

用于监测救护车患者生命体征的可穿戴智能毯子系统的设计和评估

目标。考虑到可穿戴系统的优点（例如连续监控，易于安装和显着的效率），它们还可用于在紧急情况下，尤其是在救护车中监控患者。这项研究旨在指定，建模和评估可穿戴智能毯系统，以在紧急情况下监视生命体征。方法。首先，所有智能毯系统的要求都是使用作者制作的调查表指定的，而基本要求则以软件要求规范的格式指定。然后，使用统一建模语言对这种预期的智能可穿戴毯子进行建模。最后，最重要的质量属性（即，建议的可穿戴智能毯系统的非功能性需求已通过描述性分析研究进行了评估。结果。该系统的评估结果表明，使用智能毯系统不仅可以提供所需的功能，而且还改善了重要的质量属性，例如响应时间和发送数据包的延迟（提高了14％），准确性，能耗（相比提高18％），可靠性和容错能力以及性能（比提高28％）。结论。在时间和空间，易用性以及可能的成本方面，在提供救护车时除了具有适当的质量属性外，在救护车中而不是在大型救护车舱中使用智能可穿戴毛毯将是有益的。
