Novel intrusive assisted circulation device

Abstract

The invention belongs to the field of biomedical engineering and particularly relates to an intrusive assisted circulation device used in the department of cardiac surgery. The device is characterized in that a magnetic drive mode is adopted for power transmission. The device is divided into two parts, namely an invitro driving device and an auxiliary device capable of being implanting into a human body through percutaneous coronary intervention, wherein an invitro driving device main body is a rotating magnetic field generation device capable of generating a rotating magnetic field which is strong enough; the auxiliary device implanted into the human body is internally provided with a minitype axial flow pump; a high-energy magnet is embedded in an impeller of the minitype axial flow pump, and is driven to rotate by the rotating magnetic field so as to push blood to flow; and the pump is implanted into the part, crossing over an aortic valve or pulmonic valve, of a heart, so as to play a role in assisting the heart to pump blood, thus effectively relieving the cardiac muscle load and assisting heart recovery.

Description

technical field [0001] The invention belongs to the field of biomedical engineering, and in particular relates to a novel interventional auxiliary circulation device. Background technique [0002] Heart disease is a disease with a high incidence that threatens human life at present. Various forms of heart disease will eventually lead to the failure of the patient's heart pump function, and the heart cannot effectively maintain the amount of blood circulation required by the patient's normal activities. Make the patient lose the ability to carry out physical activity, even affect the patient's normal life, and develop to serious cause the patient's death. In clinical operation, the myocardial damage of the patient during the operation causes some complications and is also a major cause of death of the patient. The most effective way to treat these diseases is to use mechanical assistance devices to effectively rest the heart and maintain myocardial blood perfusion. In this p...

Problems solved by technology

However, there is no fundamental breakthrough in the structure of the existing devices, the structure is complex, the system is cumbersome, the volume is relatively large, and it is difficult to implant

The complex structure makes it very difficult to manufacture, and the cost is inevitably greatly increased, resulting in an extremely high price, which limits the clinical use of this device and forms a contradiction with the urgent need of the clinic
