Heat stroke is a critical and health-threatening disease, triggered by thermal stimulus and progressing rapidly. It can give rise to multiple organ dysfunction syndrome (MODS), resulting in a high mortality rate. Nearly 30% of survivors will suffer with different sequelae, for instance, the neurological sequelae. Currently, the early rapid cooling is the focus of therapy for heat stroke. Therefore, it is imperative to design a cooling module suitable for the treatment of heat stroke in the field and in the hospital to realize the goal of early rapid cooling and the effective targeted temperature management (TTM). The cooling device is composed of a cooling blanket and a cooling cap. The blanket and cap are made by temperature changeable fabric. The cooling blanket comprises a backing layer, a buffer layer, a flexible heat conduction capsule body, a temperature changing component, a fixed part and a temperature sensor. The cooling cap includes a main body and two side ears, in which the main body is worn on the top of the patient's head, and the front is equipped with a flexible display screen, which is convenient for real-time monitoring the temperature of the temperature change component of the cooling blanket. The lateral ear can wrap the patient's ears and neck, and the tympanic membrane thermometer is designed to monitor the tympanic membrane temperature in real time. The tympanic membrane thermometer is also designed at the ear to monitor the tympanic auditory canal temperatures in real time.Continuous dynamic temperature monitoring can guide the duration of cooling treatment and stop cooling in time. The cooling component is portable, easy to operate, real-time temperature monitoring, excellent cooling effect and reusable. It is used for on-site first aid, transportation and continuous cooling for patients with heat stroke in the ward.
热射病是一种危急且危及健康的疾病，由热刺激引发且进展迅速。它可导致多器官功能障碍综合征（MODS），造成高死亡率。近30%的幸存者会出现不同的后遗症，例如神经后遗症。目前，早期快速降温是热射病治疗的重点。因此，设计一种适用于野外和医院热射病治疗的降温模块，以实现早期快速降温和有效的目标温度管理（TTM）至关重要。该降温装置由降温毯和降温帽组成。毯和帽由可随温度变化的织物制成。降温毯包括背衬层、缓冲层、柔性导热胶囊体、温度变化组件、固定部件和温度传感器。降温帽包括主体和两个侧耳，其中主体戴在患者头顶，前部设有柔性显示屏，便于实时监测降温毯温度变化组件的温度。侧耳可包裹患者的耳朵和颈部，鼓膜温度计设计用于实时监测鼓膜温度。耳部还设计有鼓膜温度计以实时监测鼓室耳道温度。连续动态温度监测可指导降温治疗的持续时间并及时停止降温。该降温组件便于携带、操作简便、可实时温度监测、降温效果极佳且可重复使用。它用于现场急救、转运以及对病房中暑患者进行持续降温。
