Frozen red blood cell washing machine

The function of the frozen red blood cell washing machine is to wash the frozen red blood cells and remove the residual anticoagulant and saline. The frozen red blood cell washing machine is mainly used to wash the frozen red blood cells to remove the residual anticoagulant and saline. In addition, it can also wash the anticoagulant in the raw blood, as well as the cell culture fluid, cell suspension, secretion fluid, etc.
Frozen red blood cell washing machine is a device specially used for washing frozen red blood cells (also called frozen red blood cells or cryopreserved red blood cells). Its principle is based on the balance between ice crystal formation and cell damage.
The procedure for washing frozen red blood cells is as follows:
1. First, take the frozen red blood cells out of the liquid nitrogen tank and quickly transfer them to a washing machine.
2. Then, thaw the red blood cells using a thawing solution (usually sterile water at 37°C).
3. Next, wash the thawed red blood cells with washing solution to remove impurities and residues.
4. Finally, wash the washed red blood cells with sterile water and wash again to remove residual washing solution.

The washing machine achieves the best washing effect by controlling the temperature and flow rate of the washing liquid, as well as the washing time and the number of cycles of the washing liquid. During the washing process, the ice crystals in the washing liquid will gradually dissolve and take away the water in the red blood cells to remove impurities and residues. However, this dissolution and dehydration process needs to be controlled within an appropriate range to avoid excessive ice crystal formation and cell damage.

In general, the frozen red blood cell washing machine is a highly automated device that can efficiently wash frozen red blood cells and protect the structural and functional integrity of red blood cells.
