The discussion of the heat preservation performance monitoring of the blood transport case for daily use / 国际检验医学杂志

ABSTRACT

Objective To discuss the methods of the heat preservation performance monitoring of the blood transport case and to provide the technical support for the safety of blood transportation.Methods At the different environment temperature,the amount of the cold resource was decided by the mass ratio of cold resource to blood and the temperature was automatically recorded by the intelligent temperature chip continuously,to monitor the changes of each monitoring point in the blood transport case.Results When the mass ratio of cold resource to blood was fixed at 1∶6,the cold chain of the blood transport case could keep the tempera-ture of 2-10 ℃ for 8 hours at the environment temperature of 12 ℃,It could keep the temperature of 2-10 ℃ for 4.5 hours at the environment temperature of 25 ℃,and it could keep the temperature of 2-10 ℃ for 2 hours at the environment temperature of 44℃.Conclusion When the mass ratio of cold resource to blood is fixed,as the environment temperature changes,the available time that the blood transport case keeps with the cold-chain requirement varies according to the results of the heat preservation per-formance monitoring of the blood transport case.
