Embodiment 1
[0245] Embodiment 1 Preparation of bovine blood polymerized hemoglobin
[0246] 1. Preparation method
[0247] Collect 1L of fresh bovine blood (self-raised cattle) and dilute it with a 6g / L sodium citrate solution that is 0.5 to 1 times the blood volume;
[0248] Filter the diluted blood with a 60 μm depth filter, and rinse the residue on the 60 μm depth filter with a 6 g / L sodium citrate solution until the hemoglobin passing through the filter reaches more than 95%;
[0249] Put the above-mentioned substances passing through the 60 μm deep filter on the 0.65 μm hollow fiber membrane, and use 5 to 8 times the initial blood volume of 6 g / L sodium citrate solution to wash the substance on the 0.65 μm hollow fiber membrane to make it less than 0.65 μm The substance passes through the 0.65μm hollow fiber membrane;
[0250] Add injection water to the substance intercepted by the 0.65μm hollow fiber membrane at a ratio of 1:1 to 2 to the initial blood volume to lyse red blood cel...
Embodiment 2
[0289] Example 2 Preparation of porcine blood polymerized hemoglobin
[0290] 1 L of fresh pig blood (self-raised pig) was collected, and the rest of the preparation process and detection method were the same as in Example 1.
Embodiment 3
[0291] The preparation of embodiment 3 organ perfusate
[0292] Weigh each component according to the preparation ratio per 1000mL organ perfusion solution:
