Research for saline imbibitions and diffusion during rehydration of freeze-dried pig aorta


Mengfang Liu, Zhixiong Wang, Lihao Huang, Leren Tao

The mechanism of mass transfer process for water imbibitions and diffusion of the pig aorta were analyzed. The rehydrated pig aortic which had been freeze-dried before were scanned and weighed in various stages. Then the cross-section diagrams, porosity, the ratio of the water absorption and its rate were calculated and received during the rehydration. It was demonstrated that 0.5-1h was the phase that changes about material moisture in each aspects occurred most significantly. After 3h, moisture, porosity and water absorption rate were changing dynamically and the vessels were nearly saturated. Water absorption was scaled linearly in the whole process, and the porosity declined close to the fresh from the freeze-dried vessels with higher porosity. It also pointed out that, pig aortic could be transplanted when immerged 2-2.5h in saline and normal temperature.
