BLOOD PUMPING AND PROCESSING SYSTEM

摘要

A blood processing system is described in which blood pressure readings obtained before and after passage of blood aspirated from an operative site through a membrane separator (36, 136, 236) is used by a programmed controller (83, 483) to determine the hematocrit level of the blood and to add saline solution (60) to adjust the hematocrit level to a desired level. The blood processing system contains a distributor cap to distribute wash solution to the inside of a filter (36, 126, 236) to wash out additional blood cellular material within the filter (36, 136, 236). A precollector (1318, 1400) may be used remotely from the site of the blood processing system and later joined with the system to withdraw blood contained in the precollector (1318, 1400) for processing by the blood processing system.
