AI Technical Summary
Technical Problem
Existing medical catheter pumps face challenges in completely removing air bubbles due to long pipelines, leading to residual air in the system during cleaning processes.
Method used
A ventricular assist system with a first and second three-way valve configuration allows for different conduction states to clean or prime at various locations, including the medical catheter pump cavity and passages, using high-speed cleaning assemblies and controlled flow rates to ensure thorough air removal.
Benefits of technology
The method effectively exhausts air from narrow gaps, ensuring complete priming and cleaning of the catheter pump system, preventing bubble retention and enhancing overall cleaning efficiency.

Abstract
This application discloses a ventricular assist system, a cleaning method for a medical catheter pump system, consumables and apparatus, and belongs to the art of medical devices, the ventricular assist system includes a cleaning pump assembly, a first three-way valve, a second three-way valve and a medical catheter pump, the first three-way valve includes a first valve port, a second valve port and a third valve port, the first valve port is connected to a first cleaning passage driven by the cleaning pump assembly, the second valve port is connected to a first cleaning interface of the medical catheter pump and the second three-way valve includes a fourth valve port, Including a fifth valve port and a sixth valve port, the fourth valve port is connected to a second flush passage driven by a flush pump assembly, and the fifth valve port is connected to a second flush interface of a medical catheter pump, and by switching the conduction state of the first and second three-way valves, flushing or priming is performed at different locations within the ventricular assist system, respectively, to more thoroughly remove gas at different locations, avoid residual bubbles, and thereby improve the exhaust effect of priming or flushing the entire system.
