目的 设计一种带有漏血报警装置的透析患者内瘘侧肢体舒适垫提高患者治疗舒适度，降低透析治疗过程中漏血的发 生率。方法 该装置包括肢体舒适垫部分和无线呼叫手环，肢体舒适垫上带有漏血监测装置，发生漏血时，无线手环呼叫器 会发生蜂鸣警报。将2016年3月至2017年3月拟行透析治疗的患者120例随机分为观察组和对照组，观察组60例，对照组60 例。观察组在治疗过程中应用自行研制的带有漏血感应装置的内瘘肢体舒适垫；对照组在治疗过程中应用传统内瘘肢体舒 适垫。比较两组患者的脱针率及漏血的发生率，及患者的满意率。结果 改良后带有漏血感应装置的内瘘肢体舒适垫应用方 便，患者脱针率低，漏血发生率低，患者满意率高差异有统计学意义（P<0.05）。结论 该透析用舒适垫的设计理念符合透 析患者内瘘侧肢体固定与舒适要求，同时能够感应治疗过程中内瘘肢体由于各种原因导致的漏血，为透析患者的治疗安全 增加的保障，减轻透析护理人员的工作量。

Objective To design a comfortable cushion with a blood leakage alarm device for dialysis patients in order to improve the comfort degree of patients’ internal fistula side and reduce the incidence of blood leakage during dialysis treatment. Methods The device included a limb comfortable cushion and a wireless calling bracelet. The limb comfortable cushion had a blood leakage monitoring device. A beeping alarm on the wireless bracelet will occur, when the blood leakage occurs. From March 2016 to March 2017, a total of 120 dialysis patients were randomly divided into observation group and control group, 60 cases in observation group and 60 cases in control group. During the treatment, the observation group applied our self-developed internal fistula side comfortable cushion with blood leakage monitoring device, while the control group used the traditional internal fistula limb pad. The rates of needle failure and blood leakage as well as patients’ satisfaction rate were compared between the two groups. Results The modified internal fistula limb cushion with blood leakage monitoring device is convenient to use. The patients present lower rates of needle failure and blood leakage, and have higher satisfaction rate in the observation group when compared with the control group (P<0.05). Conclusion The design concept of dialysis comfortable cushion with blood leakage monitoring device meets the requirements for the fixation and comfort of the internal fistula limbs in dialysis patients. Meanwhile, this device can montor various reasons-caused blood leakage of the internal fistula limbs during the treatment, with increased safety and reduced workload of the nursing staff.
