ABSTRACT:
A blood collection system which comprises several blood compatible sealed bags connected together by blood compatible conduits. Means for separating cryoprecipitate from blood plasma are provided. This separation is made by a filtering means. The filtering means is positioned in the outlet of one of the bags of the system. After the blood cells have been removed by a prior step, the remaining blood plasma is collected in the bag which has the filtering means in the outlet. In this bag, the blood plasma is frozen and then slowly thawed. Factor VIII rich cryoprecipitate forms in this bag as part of the freezing and thawing process. As the plasma melts, it flows from the bag through the filtering means. The filtering means positioned in the outlet of the bag retains the cryoprecipitate. Thus, the separation of Factor VIII rich cryoprecipitate from the blood plasma is effected.
