Heart failure, which is the final stage of most cardiovascular diseases, has a complex pathogenesis, a high treatment difficulty and a poor prognosis for patients, has become a research hotspot in the field of cardiovascular diseases. Patients with severe heart failure often need to have their lives prolonged by transplanting their hearts. However, heart transplantation has problems such as donor difficulty and immune rejection. With advances in technology, artificial hearts are being proposed and soon enter the clinical field of view.
An artificial heart is a mechanical device made of artificial material to temporarily or permanently partially or completely replace the heart function, pushing blood circulation. Artificial hearts are classified into auxiliary artificial hearts and complete artificial hearts. Ventricular assist devices are the most effective treatment of all types of end-stage heart failure recognized worldwide. At present, heart failure is mainly left heart failure, so a left ventricular assist device (Left Ventricular Assist Device, LVAD) is also the most widely used artificial heart at present.
There are many devices currently being developed worldwide, taking concentric CH-VAD as an example, that include blood pumps, extracorporeal controllers, rechargeable lithium batteries, wearable systems, adapters, monitors, and the like. The blood pump, namely the full-magnetic suspension type artificial heart CH-VAD, is organically combined with the design of the flow path in the pump through the magnetic suspension design, so that the blood pump design covering the two aspects of core technologies of rotor support and hydrodynamic design is formed optimally, and the blood pump is small in size and good in blood compatibility. In daily operation, the extracorporeal controller supplies power to the blood pump, and the user interface is the main channel for the user to interact with the system to provide visual display.
The external controller is connected with the blood pump through the percutaneous cable, the defibrillation insulation sleeve and the percutaneous cable extension line, and the connection mode is the only channel for connecting the blood pump with the external controller, so that the normal operation of the connection channel is ensured to be important.
When the blood pump normally operates, the extracorporeal controller needs to be replaced for some reason, in the process, the percutaneous cable and the extension line of the percutaneous cable need to be disconnected, namely, the connection between the blood pump and the extracorporeal controller is disconnected, and if the blood pump is directly disconnected, the blood pump can stop operating, and life danger is caused to a patient. It is required to ensure proper operation of the blood pump when the extracorporeal controller is replaced. At present, the external controller is replaced, so that the patient needs to arrive at a designated hospital to be replaced by a professional, the process is complicated, and if the time is too long, the patient is easy to be dangerous. The invention aims to solve the problem, and under the condition that the connecting channel is only, the external controller can be conveniently replaced, and the blood pump can be ensured to normally operate in the replacement process.
