Abstract:
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.
