Systems and methods for salvaging red blood cells for autotransfusion

摘要

Systems and methods for salvaging blood cells from an absorbent material are disclosed. In one exemplary aspect, such as system includes a rotatable basin having perforations to allow rinse solution from a stationary basin to reversibly flow therethrough to wash the blood cells from the absorbent material, thereby forming an effluent solution. The system further includes a hemoconcentrator in fluid communication with the stationary basin having first and second fluid outputs for discharging a diluent solution and a blood cell discharge solution from the effluent solution respectively. The blood cells can be salvaged from the blood cell discharge solution. The second fluid output is in fluid communication with the stationary basin for recycling the diluent solution as the rinse solution.

主权项

1. An assembly for salvaging blood cells from an absorbent material, comprising:
a first basin having perforations to allow a rinse solution to wash said blood cells from said absorbent material into a second basin to form an effluent solution; an elongate rotor having a first rotor portion fixedly attached to a center of mass of said first basin that defines an axis of rotation about which said first basin can axially rotate; and a hemoconcentrator in fluid communication with said second basin having first and second fluid outputs for discharging a diluent solution and a blood cell discharge solution from said effluent solution respectively; wherein said first fluid output is in fluid communication with said second basin for recycling said diluent solution as said rinse solution.
