  • Blood pumping and processing system
    Patent number: 5423738
    Abstract: 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 is used by a programmed controller to determine the hematocrit level of the blood and to add saline solution 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 to wash out additional blood cellular material within the filter. A precollector 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 for processing by the blood processing system.
