Convertible extracorporeal blood perfusion systems
First Claim
1. A convertible extracorporeal blood perfusion system for receiving venous blood from a patient and for returning oxygenated blood to the patient in a cardiopulmonary bypass procedure comprising:
- a closed-loop cardiopulmonary bypass system; and
a circuit for converting between the closed-loop cardiopulmonary bypass system and a cardiopulmonary bypass system containing a venous reservoir, the circuit for converting comprising a venous reservoir that can be fluidly connected to a venous line from the patient and that can be fluidly connected to the inlet of a first pump, the first pump being part of the closed-loop cardiopulmonary bypass system, the closed-loop cardiopulmonary bypass system comprising a bubble removal device fluidly connected to the inlet of the first pump.

20. A convertible extracorporeal blood perfusion system for receiving venous blood from a patient and for returning oxygenated blood to the patient in a cardiopulmonary bypass procedure comprising:
-
a closed-loop cardiopulmonary bypass system; and
a circuit for converting between the closed-loop cardiopulmonary bypass system and a cardiopulmonary bypass system containing a venous reservoir, the circuit for converting comprising a venous reservoir that can be fluidly connected to a venous line from the patient and that can be fluidly connected to the inlet of a first pump, the first pump being part of the closed-loop cardiopulmonary bypass system, the convertible extracorporeal blood perfusion system comprising a level sensor that is operable to detect a blood level in the venous reservoir that is below a predetermined level and is operable to send a signal to a controller that automatically stops the flow of blood from the venous reservoir. - View Dependent Claims (21, 22)
