Continuous autotransfusion filtration system |
摘要 |
A progressive filtration system for a chest drainage unit during continuous autrotransfusion comprising a gross filter for filtering incoming blood at the inlet portion of a collection chamber of a chest drainage unit and a conventional fine micron filter assembly located at the bottom portion of the collection chamber for refiltering collected blood prior to reinfusion of that blood back to the patient. The micron filter assembly includes a valve cap at the top portion of the assembly that functions as a plug to seal the top portion of the assembly and as a one way valve that permits reflux of later developing blood clots that might clog the tubing once the blood has already passed through the assembly.The valve cap is also adapted for sealing engagement with a drop tube that places the filter assembly in fluid flow communication with an outlet of the collection chamber located at the top portion of the chamber. |
