Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and in particular to an artificial intelligence-based magnetic levitation heart pump and its usage method. Background Technology

[0002] Heart failure refers to a syndrome caused by impaired systolic and / or diastolic function of the heart, which fails to adequately pump venous blood back to the heart, leading to blood pooling in the venous system and insufficient blood perfusion in the arterial system. Current technologies for adjuvant therapy in heart failure patients include artificial hearts, which can be divided into blood pumps and power pumps. Blood pumps use an electric motor or magnetic levitation as power to drive an impeller inside the pump, drawing blood from the ventricles of the heart and pumping it into the aorta through an artificial blood vessel. Power pumps, on the other hand, are external or internal devices that inflate and deflate functional units surrounding the heart in complete synchronization with the cardiac cycle, compensating for the contraction and relaxation of the failing heart and thus improving or completely restoring cardiac function.

[0003] Existing blood pumps require direct contact with blood, which can easily cause complications and secondary damage, and have limited effect on improving heart failure and restoring cardiac function. Existing power pumps abroad (Harvard University's myocardial pump and Munich University's pericardial pump) have a loud main unit power source when operating, and the main unit is large and not easy to be fully implanted in the body, making them inconvenient to carry. At the same time, existing power pumps use both air pumps and air pumps at the same time, creating a high-pressure air inflation and low-pressure air suction effect. The use of more pumps increases the structural volume, and the imbalance of high and low pressure can deform the shape of the heart, thereby affecting the morphology of the heart structure. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and provides an artificial intelligence heart magnetic levitation main pump and its usage method. It aims to solve the problem that the mechanical structure of the power pump in the prior art is too large and difficult to install in the body. At the same time, it optimizes the structure of the power pump so that it can be used in conjunction with the intelligent heart.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an artificial intelligence cardiac magnetic levitation main pump, comprising: a support frame and a rotor and an air pump unit mounted on the support frame.

[0006] The support frame has a mounting hole at its center and a plurality of positioning posts and fixing posts in its circumference. The plurality of positioning posts and fixing posts are spaced apart, and the positioning posts are provided with a plurality of electromagnetic coils.

[0007] The rotor includes: a central column installed in the mounting hole and a disc connected to the central column. A pusher is installed at the upper end of the central column. The disc has a groove along the circumference, and the width of the groove is greater than the diameter of the positioning column. Several permanent magnets are spaced apart on the inner and outer walls of the groove.

[0008] The air pump unit includes: a piston head and an air pump connected by a connecting rod. The piston head abuts against the push head, and the connecting rod is slidably connected to the fixed column. The air pump is provided with a piston and a spring. The piston is connected to the connecting rod and the spring respectively, and the air outlet of the air pump is connected to several air bags through gas conduits.

[0009] It should be noted that the positioning posts are cylindrical, and several positioning posts are arranged around the circumference of the circular support frame. The fixing posts are used to limit the movement trajectory of the connecting rod and fix the position of the air pump.

[0010] In a preferred embodiment of the present invention, a plurality of electromagnetic coils and a plurality of permanent magnets correspond one-to-one. Utilizing the property of electromagnetism, the permanent magnets rotate along both sides of the coils after being energized.

[0011] In a preferred embodiment of the present invention, the polarities of the several permanent magnets are opposite on opposite sides in the horizontal direction.

[0012] In a preferred embodiment of the present invention, the electromagnetic coil is connected to the battery and the AI ​​control platform, and the AI ​​control platform is connected to the heart through a sensor, which is a ventricle and arterial pressure sensor, used to transmit the R wave of the heartbeat to the control platform, and the control platform adjusts the current in the coil.

[0013] In a preferred embodiment of the present invention, the cross-section of the air pump is arc-shaped, and the volume of the air pump is 30-35ml, and the internal air chamber volume is 20-25ml.

[0014] In a preferred embodiment of the present invention, the plurality of airbags are further connected to a plurality of pneumatic modules, the plurality of pneumatic modules including an inner plate and an outer plate, and the outer plate is connected by an adjustable stainless steel ring, and the airbags are installed between the inner plate and the outer plate.

[0015] In a preferred embodiment of the present invention, the bottom of the inner plate and the outer plate are rotatably connected, and the inner plate is also provided with a conduit for connecting the airbag and the gas conduit.

[0016] In a preferred embodiment of the present invention, the air pump is further connected to an air reservoir, which is used to compensate for the air volume lost in the air pump.

[0017] This invention also provides a method for using an artificial intelligence-based magnetic levitation heart pump, comprising the following steps:

[0018] S1. Equipment installation: After the patient opens the chest, fix the electrocardiogram and arterial pressure sensors to the heart or the anterior wall of the ascending aorta, implant each pneumatic module around the heart one by one, and implant the main unit under the skin of the left anterior chest wall at the same time.

[0019] S2: Synchronous contraction: The sensor receives the R wave of the heart, and the control platform controls the current on and off. When the heart contracts, the coil is energized, the magnetic levitation rotor rotates counterclockwise, and the pusher pushes the piston head from the starting point to the end point and then automatically disengages, completing one inflation activity; the gas in the arc-shaped air chamber is pushed into the air sac around the heart, completing the inflation of the air sac during the contraction period. At this time, the inner plate squeezes the heart.

[0020] S3. Synchronous diastole: When the heart begins to diastole, the coil is de-energized. After the pusher pushes the piston head from the starting point to the ending point and automatically disengages, the spring in the air chamber pushes the piston back to the starting point, completing the deflation of the balloon, that is, the heart completes the diastolic activity.

[0021] S4. Repeat steps S2 and S3 to achieve the purpose of assisting cardiac function.

[0022] In a preferred embodiment of the present invention, the outer surface of the heart is divided into several functional areas, and several inner plates are designed with the same shape as several functional areas to achieve the best auxiliary effect. The inner plates with different shapes can ensure that the inner plates fit closely to the surface of the heart and can move completely synchronously when assisting the heart's contraction and relaxation.

[0023] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0024] This invention features a magnetic levitation gas-powered pump to replace the traditional magnetic levitation blood pump, used in conjunction with a pneumatic module. Utilizing the principle of electromagnetism, permanent magnets are placed on both sides of a positioning column equipped with several electromagnetic coils. Since the coil positions are fixed, the magnets move along a predetermined track after being energized, i.e., the rotor rotates around the central column. Simultaneously, the rotor is suspended on the support frame without contacting it. This solves the problems of existing power pumps, which mostly use motors and air pumps as power sources, resulting in high noise levels during operation and potential damage to surrounding tissues due to heat generated by the pump body. Furthermore, the volume of the air chamber in contact with the rotor is constant, eliminating the problem of compression or pulling on the heart due to unequal supply and output pressures, thus preventing secondary damage to the heart.

[0025] In this invention, the main power pump is connected to the airbags in several pneumatic modules, and the inner plate shape of the pneumatic module is designed to be the same as the shape of several functional areas of the heart. When the heart contracts, it can fit closely to the surface of the heart, improving the cardiac assist effect. At the same time, the total gas volume required by the airbags in several pneumatic modules is smaller than that of myocardial pumps and pericardial pumps, and the structure is simple and the overall volume is small. In practical applications, this creates the possibility of overall implantation of the device. The implantation method is simple, the surgical operation is easy to master, the indications are wide, and it can be widely promoted.

[0026] Most existing implantable cardiac assist devices work by pumping blood from the ventricles into the aorta. Their main function is to replace part of the heart's work, allowing the heart to rest fully. However, they do not eliminate the core factors that cause ventricular failure, so heart failure is not fundamentally improved. In addition, complications such as secondary damage to the blood system and heart caused by the blood pump are unavoidable. In severe cases, it can lead to internal organ bleeding or heart transplantation. In contrast, the power pump of this invention does not come into direct contact with blood. Instead, it indirectly contacts the heart by providing air pressure. Furthermore, the main pump of this invention can be miniaturized and implanted inside the human body. Its manufacturing materials are cost-effective, greatly reducing the economic burden on patients. Attached Figure Description
