Combined Blood Pump and Oxygenator System With Dual Pumps
Summary
USPTO published patent application US20260097162A1 for a combined blood pump-oxygenator system featuring dual pumps and dual oxygenators. The system is designed for cardiopulmonary bypass and extracorporeal blood processing, with a pump control unit that varies flow rates through each oxygenator to optimize patient perfusion and oxygenation.
What changed
USPTO published patent application US20260097162A1 disclosing a blood pump-oxygenator system with two independent pump-oxygenator circuits. The system includes dual blood pumps and dual oxygenators controlled by a pump control unit to adjust flow rate ratios between oxygenators, enabling optimized extracorporeal blood processing for cardiopulmonary bypass.
Medical device manufacturers developing cardiac support systems, cardiopulmonary bypass equipment, or extracorporeal membrane oxygenation (ECMO) devices should review the patent claims for potential infringement concerns, licensing opportunities, or R&D guidance. The dual-circuit design may influence future product development strategies in the cardiac assist device market.
What to do next
- Monitor patent prosecution status for grant or rejection
- Review claims for R&D and product development alignment
- Assess competitive landscape for similar extracorporeal circulation technologies

Abstract
A blood pump-oxygenator system for increasing perfusion and oxygen level in a patient comprises a blood flow inlet and outlet forming a circuit operable as a cardiopulmonary bypass system for extracorporeal processing of blood, a first blood pump and first oxygenator. The first blood pump conveys blood through the circuit from the patient into the blood flow inlet, through the first oxygenator and out of the blood flow outlet back into the patient. The system further comprises a second blood pump and second oxygenator. The second blood pump conveys blood through the circuit from the patient into the inlet, through the second oxygenator and out of the outlet back into the patient. A pump control unit controls the first and second pumps to increase or decrease blood flow rate through the respective oxygenator to vary a ratio of flow rates of blood through the first and second oxygenators.
