Technical Field
The invention belongs to the technical field of medical devices, and particularly relates to a movable suspension type blood pump of an artificial heart-lung machine.
Background
The extracorporeal circulation technology is the most critical link in the heart surgery process, namely, the artificial heart lung is used as life support, and the heart lung function of a patient is temporarily replaced in the heart surgery. In the requirements for artificial heart and lung, the blood pump is used as the power source of the artificial heart and is placed at the most important position, and the blood pump is matched with an extracorporeal circulation pipeline and an intubation tube and is finally connected with the great artery and vein of a human body, so that the continuous input and output of blood circulation are realized, namely the artificial heart. Since human blood in extracorporeal circulation is in contact with artificial blood vessels (foreign body surfaces other than human blood vessels), a series of blood active component activations, inflammatory factor releases, and the like are generated, which are closely related to the prognosis of patients with cardiac surgery. Extracorporeal circulation would therefore require a stable blood pump power source and better biocompatible consumables. Improving biocompatibility and reducing the contact area between the extracorporeal circulation artificial material and blood are also very critical measures.
The extracorporeal circulation artificial heart-lung machine is always fixed with four to five pump head positions, the pump head positions are arranged in a straight line and cannot move, extracorporeal circulation pipelines with different lengths need to be used for matching connection with the pump head positions, in addition, the venous blood needs to be drained by siphoning of gravity, and the membrane oxygenator is also arranged at a low position, so the matching lengths of the oxygenator and the pump head pipelines are both longer and fixed, the system precharge capacity is large, the blood dilution degree is also large, the inflammatory reaction activation degree is high, and the organ complications are more.
