医用冷藏运输箱的设计与制作

Design and Manufacture of Medical Shipping Refrigerated Box

目的研制一套用于野外环境的方便生物制品储存和转运的低温医用冷藏运输箱。方法采用半导体致冷器件和相变储能材料作为致冷和储冷手段,在有电源供应情况下由半导体器件致冷,并通过相变储能材料蓄存;在无电源供给时,由相变储能材料继续保持生物制品的低温状态。结果医用冷藏运输箱的设计与制作,解决了医学实验和临床诊疗过程中遇到的血液、疫苗等生物制品的储存和转运问题,延长了生物制品的保冷时间。结论医用冷藏运输箱不仅在医疗领域有广泛的应用价值,而且在食品等其它领域也将有广阔的应用前景。

Objective To develop a set of low temperature medical shipping refrigerated box for storage and shipping for biologicals in field environment. Methods Semiconductor cooling device （SCD） and phase change energy storage materials （PCESM） were adopted as the means for refrigeration and coolness storage, coolness was produced by SCD and stored by PCESM while power source present, and low temperature state for biologicals was keep by PCESM. Results The problem for biologicals storage and shipping in low temperature state for medical experiment and clinic was resolved. Conclusion Medical shipping refrigerated box can be used not only in medical, but also in other field such as food storage and shipping, etc.
