Examples
Embodiment 1
[0014] The preparation method of this platelet preservation solution is:
[0015] Dimethyl sulfoxide (DMSO) and fresh water for injection are prepared into a solution with a volume concentration of 50%, then stirred evenly, and medicinal charcoal is added; then the resulting solution is decarburized by filtration through a titanium rod, and then passed through a 0.45um micropore Filter through a filter membrane, and then filter through a 0.22um microporous membrane to obtain the platelet preservation solution. The dosage of medicinal charcoal is to add 2g of medicinal charcoal to every 1000ml platelet preservation solution.
Embodiment 2
[0017] The preparation method of this platelet preservation solution is:
[0018] Dimethyl sulfoxide (DMSO) and fresh water for injection are prepared into a solution with a volume concentration of 85%, then stirred evenly, and medicinal charcoal is added; then the obtained solution is decarburized by filtration through a titanium rod, and then passed through a 0.45um micropore Filter through a filter membrane, and then filter through a 0.22um microporous membrane to obtain the platelet preservation solution. Wherein the amount of medicinal charcoal is to add 10g of medicinal charcoal to every 1000ml of platelet preservation solution.
Embodiment 3
[0020] The platelet preservation solution obtained in Example 1 was stored at -14°C for 3 hours, then at 14°C for 3 hours, and this cycle was repeated once, and finally stored at room temperature.
