研制一种适用于野外救治热射病的降温袋，实现野外环境下早期快速有效降温的治疗目标。该降温袋由头罩、体罩（背部、双侧体部及前部）、固定带及把手提带组成，长200cm、宽60～70cm（可调节）。头罩、体罩设有数个冷源放置夹层，体部上、中、下分别设有固定带，头顶部、体部上下设有把手提带；折叠体积为26cm×20cm×9cm，重量为1．4k。使用时展开降温袋，将冷源生效，配置在降温袋的相应位置上；除去患者装备和外衣使其平卧于降温袋内，双臂自降温袋两侧体部留空处伸出，封闭双侧拉链，可用固定带包裹患者并固定。在降温过程中随时监测患者体温，调整、更换冷源；同时监测血压、完成静脉输液等必要的监护治疗措施，可使用手提带实现患者移动及救援转运。该降温袋具有便于携带、操作方便、降温效果确切、冷源布控灵活、便于观察患者生命体征、利于搬运、成本低、可重复使用的特点。

Cooling bag for heat stroke in wild field was invented in order to fulfill rapid cooling for heat stroke in field environment. The cooling bag is composed of the hood, the body cover （which is made up of the anterior portion, the linking, and the posterior portion）, the fixed straps, the handles. The length is 200 cm, the regulative width is 60-70 cm, the folding volume is 26 cm × 20 cm × 9 cm, and the weight is 1.4 kg. There are a number of pockets for the cold sources in the hood and the body cover. Fixed straps are set in the upper, middle and lower of the bag. The handles are set in the hood and the body covers. Usage： put the activated cold sources in the pockets, then put off the patient＇s clothes, stretch his/her arms into the linking, zipper up and wrapped up by the fixed straps; the amount of cold sources can be adjusted or changed according to the temperature. The patient＇s temperature, blood pressure, intravenous infusion can be monitored during the cooling course. The handles in the hood and the body cover allow the patient to be easily moved and be transferred in rescue. The cooling bag for heat stroke in field has good cooling effect, and are reusable and easy to be carried, operate, monitor and move, with low cost, which make it popularization and application.
