摘　　要：目的真空隔热板是一种新型高效的保温材料,可作为储运血箱的箱体材料,以增强储运血箱的保温性能。方法真空隔热箱(VIP箱)作为实验组,瓦楞纸箱+泡沫运血箱(EPS箱)作为对照组。两组放入等量的相变蓄冷剂和4℃水袋,用可录式电子温度监控仪记录密封箱体内的温度变化情况,并测量两种箱体储血0、4及7 d时血样的游离血红蛋白(FHb)浓度和钾离子浓度。结果 36 h后,EPS箱温度上升较快,且直到60 h温度始终显著高于VIP箱。此外,VIP箱<10℃的时间为(60.7±0.6)h,而EPS箱为(54.2±3.0)h,两组数据之间的差异具有统计学意义(P<0.05)。储存第7天,VIP箱中FHb浓度[(605.26±74.63)mg/L]显著低于EPS箱[(1327.60±187.41)mg/L](P<0.05);且储存第7天,VIP箱中钾离子浓度[(22.7±0.4)mmol/L]显著低于EPS箱[(24.6±0.6)mmol/L](P<0.05)。结论 VIP箱<10℃的时间较长,保温性能较好,血液的保存质量显著优于EPS箱。新型保温箱体材料的研制将有效提升血液冷藏保障能力,具有重大研究价值和实际应用意义。Objective To study the thermal insulation properties of vacuum insulated panel（VIP） used as materials for blood transportation kits.Methods A VIP transportation kit was taken as test group,and a conventional transportation kit was taken as control.Phase change cool storage materials of the same amount and 4℃ water bags were put into both kits.A recordable electronic thermometer was used to record the temperature within the two kits,and free hemoglobin（FHb） and potassium ion concentration were measured at 0,4,and 7 days after blood storage.Results The temperature in the conventional transportation kit increased faster after 36 h,and was significantly higher than in the VIP transportation kit until 60 h.Besides,the VIP transportation kit kept the temperature under 10℃ for（60.7 ± 0.6） h,compared to（54.2 ± 3.0） h in the conventional transportation kit.FHb concentration was significantly lower in the VIP transportation kit[（605.26 ± 74.63） mg/L] than in the conventional transportation kit [（1327.60 ± 187.41） mg/L] at day 7（d 7）,so was the potassium ion concentration in the VIP transportation kit [（22.7 ± 0.4） mmol/L] compared to [（24.6 ± 0.6）mmol/L] in the transportation kit at d 7.Conclusion The VIP transportation kit keeps the temperature under 10℃ for a longer time,and the blood quality of preservation is better than that of the conventional transportation kit.Novel heat preservation material can improve health support ability,and is of great value and significance.
