Application of phase change materials in the long-distance transportation of blood / 中国输血杂志

ABSTRACT

Objective To study the effects of phase change material (cooling agent) on the quality of blood after long-distant transportation.Methods A total of 12 bags, packed with pre-chilled phase change materials, were put into regular blood transportation kit, and the new blood transportation kit, which was developed by our hospital. In each kit there were 54 U of red blood cell suspensions. The temperatures in the kit were recorded during the transportation at different times.Results The temperature in the kit was kept between 1—7℃ during the 72h transportation. The temperature met the needs of red blood cell transportation.Conclusion Phase change material could be used as an effective cooling agent for long distance blood transportation.
