Abstract
An integrated, vacuum-driven shed blood processing system that collects, dilutes, filters and washes postoperatively shed blood and concentrates red blood cells for reinfusion to the patient. The location of the centrifuge bowl between the surgical site and the vacuum source used to clean the site allows the immediate collection of shed blood in the bowl without an intermediate reservoir or an additional pump. In conjunction with a modified centrifuge bowl having a sealed aperture in its floor that permits reinfusion directly from the bowl without an additional reinfusion bag or reverse pump, this configuration processes blood for reinfusion using fewer steps and components yet without loss of functionality. Dilution of the blood upon its introduction into the system reduces the tendency to coagulate and allows the use of lower bowl rotation speeds. Slower rotation reduces red blood cell damage and lowers power requirements, which improves portability.
