Claims (14)

1. Fremgangsmåde til konservering af blodplader, hvilken kan anvendes til at forlænge levetiden for anvendelige blodplader til ud over fem dage, omfattende de følgende trin: a) at placere en sammensætning omfattende blodplader i en gasblanding omfattende xenon og oxygen, hvor gasblandingen omfatter 79 % - 95 % xenon og 5 % - 21 % oxygen, og et kombineret indhold af xenon og oxygen i gasblandingen er mindst 95 %; b) at opretholde sammensætningen omfattende blodplader i nærvær af gasblandingen i et første tidsrum og ved en første temperatur, indtil xenonen i gasblandingen har i det mindste delvist mættet sammensætningen omfattende blodplader; c) at afkøle sammensætningen omfattende blodplader, som er i det mindste delvist mættet med xenon, til en anden temperatur, hvor den anden temperatur er mindre end den første temperatur; og d) at holde sammensætningen omfattende blodplader på den anden temperatur i et andet tidsrum.
2. Fremgangsmåde som defineret i krav 1, hvor gasblandingen omfatter 86 % - 88 % xenon og 12 % -14 % oxygen.
3. Fremgangsmåde som defineret i krav 1 eller krav 2, hvor den første temperatur er 18°C-37°C.
4. Fremgangsmåde som defineret i et af kravene 1-3, hvor den første temperatur er 18°C-23°C.
5. Fremgangsmåde som defineret i et af kravene 1-4, hvor trinnet med at opretholde sammensætningen omfattende blodplader i nærværet af gasblandingen i et første tidsrum og ved en første temperatur omfatter at udsætte sammensætningen omfattende blodplader for et tryk på mindst 2 bar.
6. Fremgangsmåde som defineret i et af kravene 1-5, hvor trinnet med at opretholde sammensætningen omfattende blodplader i nærværet af gasblandingen i et første tidsrum og ved en første temperatur omfatter at udsætte sammensætningen omfattende blodplader for et tryk på 2-10 bar.
7. Fremgangsmåde som defineret i et af kravene 1-6, hvor det første tidsrum er 5 sekunder til ti timer.
8. Fremgangsmåde som defineret i et af kravene 1-7, hvor det første tidsrum er 60 sekunder til fem timer.
9. Fremgangsmåde som defineret i et af kravene 1-8, hvor den anden temperatur er 0,1 °C-6°C.
10. Fremgangsmåde som defineret i et af kravene 1-9, hvor den anden temperatur er 3°C-6°C.
11. Fremgangsmåde som defineret i et af kravene 1-10, hvor det første tidsrum er mindre end det andet tidsrum.
12. Fremgangsmåde som defineret i et af kravene 1-11, hvor det første tidsrum er mindre end det andet tidsrum, og det andet tidsrum er 5-21 dage.
13. Fremgangsmåde som defineret i et af kravene 1-12, hvor sammensætningen omfattende blodplader er mindst 80 % fuld mætning med xenongassen i løbet af det første tidsrum og ved den første temperatur.
14. Fremgangsmåde som defineret i et af kravene 1-13, hvor sammensætningen placeres i en pose eller en beholder, der er gennemtrængelig for gasblandingen, og sammensætningen udsættes for gasblandingen i et hermetisk lukket kammer.
