Abstract
Description
Technical Field
[0001] This application belongs to the field of medical device technology, specifically relating to an intelligent bionic heart and its operating method. Background Technology
[0002] Artificial hearts, mechanical hearts, bionic hearts, etc., generally refer to devices that partially or completely replace the human heart's pumping function using mechanical or biomechanical means. The history of human research and utilization of artificial hearts began in the mid-20th century. With decades of development, artificial mechanical pumping devices have made many breakthroughs and have gone through a development process from axial flow pumps to centrifugal pumps, achieving great progress.
[0003] However, most artificial hearts currently on the market suffer from fatal problems such as large size, short lifespan, and thrombus formation. They may also cause a major imbalance in blood supply between the left and right ventricles, which could lead to various diseases and multiple organ failure after implantation. This is a huge shortcoming in the safety of existing artificial hearts, which urgently needs to be addressed, or more effective and reliable methods need to be found. Summary of the Invention
[0004] The purpose of this application is to provide an intelligent bionic heart and its operating method, which can effectively and reliably solve the major problem of insufficient safety performance of existing artificial hearts.
[0005] In a first aspect, embodiments of this application provide an intelligent bionic heart, which includes: a shell, a left ventricle, a right ventricle, an ingress valve, an egress valve, an artificial blood vessel, a power system, a blood volume regulation system, an intelligent control system, and sensors;
[0006] The left and right ventricles are located on the left and right sides of the shell, respectively. Each of the left and right ventricles has two openings, and the inlet valve and the outlet valve are respectively located at the openings. There are four artificial blood vessels, one end of which is connected to the four openings of the left and right ventricles, and the other end is connected to the human aorta, the pulmonary aorta, the left atrial incision, and the right atrial incision, respectively.
[0007] The power system has two push-pull plates connected to each end, one attached to the left ventricle and the other to the right ventricle. The power system drives the push-pull plates in a reciprocating linear motion. When the push-pull plate moves towards the left ventricle, pushing and pumping blood out of the left ventricle, the right ventricle expands its volume and draws in blood. Conversely, when the push-pull plate moves towards the right ventricle, pushing and pumping blood out of the right ventricle, the left ventricle expands its volume and draws in blood. This cyclical motion of the power system causes the left and right ventricles to continuously draw in and pump out blood, thus promoting blood circulation in the body.
[0008] The blood volume regulation system is electrically connected to the intelligent control system. The blood volume regulation system is used to regulate the blood supply and demand balance between the left and right ventricles. When the intelligent control system detects an imbalance in the blood supply between the left and right ventricles through the sensor and needs adjustment, it controls the blood volume regulation system to move towards the ventricle with a larger blood pumping volume, squeezing the ventricle with a larger blood pumping volume to reduce its expansion and the amount of blood drawn in and pumped out. When the intelligent control system detects that the blood supply and demand of the human body have reached a balance, it controls the blood volume regulation system to reverse its operation, no longer squeezing the ventricle with a larger blood pumping volume that is being squeezed, or reducing the squeezing of the ventricle with a larger blood pumping volume as needed, so that the blood supply and demand between the left and right ventricles can reach a balance.
[0009] Optionally, the intelligent control system includes at least a circuit board and chip, and software program. The intelligent control system is used to detect the user's body index through different sensors. The body index includes at least: body movement speed, body temperature, respiratory rate, height, and weight.
[0010] The intelligent control system sets the initial number of runs of the power system based on the user's height, weight, and body mass index. It also adjusts the number of runs of the power system in real time according to changes in the user's body movement speed, body temperature, and respiratory rate, thereby adjusting the pumping frequency of the left and right ventricles to adapt to the blood supply under different exercise conditions.
[0011] Optionally, the blood volume regulation system includes an regulating motor, a screw, a fixed guide slide, and a squeezing component. The regulating motor is connected to the screw, the screw is connected to the squeezing component, and the fixed guide slide is fixedly installed for the smooth operation of the squeezing component. When the intelligent control system detects an imbalance in the blood pumping volume between the left and right ventricles through the sensor, it controls the regulating motor to rotate, causing the screw to drive the squeezing component to move towards the ventricle with a larger blood pumping volume, thereby squeezing the ventricle with a larger blood pumping volume, reducing its expansion and blood pumping volume.
[0012] Optionally, the power system includes a power motor, a telescopic component, a power guide slide rod, and a push-pull plate. The power motor drives the telescopic component to reciprocate in a linear motion. The telescopic component is connected to the push-pull plate and reciprocates in a linear motion to push and pull the left and right ventricles. The power guide slide rod is fixedly installed for the smooth operation of the telescopic component.
[0013] Optionally, the intelligent bionic heart also includes a power supply system, which includes a built-in battery, a built-in receiving power coil, an external battery, and an external transmitting power coil. The built-in receiving power coil can be implanted subcutaneously and is electrically connected to the built-in battery and the intelligent control system. The external transmitting power coil is correspondingly positioned inside and outside the human body to supply power to the devices inside the body. The external battery can be integrated with an external circuit board and chip into a module and placed in a pocket of a vest or belt worn outside the human body, and connected to the external transmitting power coil to supply power to the human body.
[0014] Optionally, the intelligent bionic heart also includes a communication system, which includes a built-in communication module, an external communication module, and an external early warning device. Both the communication system and the power supply system are electrically connected to the intelligent control system, and the connection between the built-in and external parts of the communication system and the power supply system is wireless.
[0015] Optionally, the left ventricle, the right ventricle, the artificial blood vessel, the ingress valve, and the egress valve—all components that come into contact with blood—are made of biocompatible materials. The surfaces of all components in the intelligent bionic heart that come into contact with blood can still be coated with biocompatible materials.
[0016] Optionally, the intelligent bionic heart further includes a support frame and a locking ring. The support frame is used to fix the power system and the blood volume regulation system. The locking ring is used to fix and connect the tube opening to the artificial blood vessel, the ingress valve, and the egress valve, as well as to fix and connect the shell, the left ventricle, and the right ventricle in combination.
[0017] Optionally, the housing is a multi-component assembly. After the internal components are installed, the multiple components are combined by snap rings or welding to form a sealed whole. Alternatively, the housing is a complete housing with an opening, and the opening is sealed with a back cover after the internal components are installed.
[0018] Secondly, embodiments of this application provide a method for operating an intelligent bionic heart, wherein the method is applied to the intelligent bionic heart described in the first aspect, and the method includes:
[0019] Acquire information on the operation of the intelligent bionic heart and various movements and functions of the user's body;
[0020] Based on the operating information of the intelligent bionic heart and the user's various movements and operating information, the system provides prompts and controls the operating status of the power system and blood volume regulation system.
[0021] In this embodiment, sensors are used to detect the blood supply to the left and right ventricles and upload the data to the intelligent control system. When the blood supply to the left and right ventricles is unbalanced, the intelligent control system immediately controls the blood volume regulation system to move towards the ventricle with a larger blood volume. This causes the blood volume regulation system to compress the ventricle with a larger blood volume, thereby reducing the expansion of the ventricle with a larger blood volume and reducing the amount of blood drawn in and pumped out by the ventricle. This balances the blood supply to the left and right ventricles and prevents the intelligent bionic heart from experiencing an imbalance in blood supply to the left and right ventricles during use. This overcomes the major defect of poor safety in existing artificial hearts. At the same time, the technology disclosed in this embodiment is novel and unique, small in size, highly practical, and has excellent effects and operability. Attached Figure Description

[0053] In the description of this application, the "adhesive connection" means that the push-pull plate and the ventricular diaphragm or soft capsule are simply attached together, or the push-pull plate and the ventricular diaphragm or soft capsule can still be fixedly connected.
[0054] Please see Figures 1 to 24 This application provides an intelligent bionic heart, which includes: a shell, a left ventricle 24-A, a right ventricle 24-B, an ingress valve, an egress valve, an artificial blood vessel, a power system, a blood volume regulation system, an intelligent control system, and sensors.
[0055] The left ventricle 24-A and the right ventricle 24-B are located on the left and right sides inside the shell, respectively. Each of the left ventricle 24-A and the right ventricle 24-B has two openings, and the inlet valve and the outlet valve are respectively located at the openings. There are four artificial blood vessels, one end of which is connected to the four openings of the left ventricle 24-A and the right ventricle 24-B, and the other end is connected to the human aorta, the pulmonary aorta, the left atrial incision, and the right atrial incision, respectively.
[0056] Please see further. Figure 1 and Figure 2 The shell consists of two parts: the left shell 1-B and the right shell 1-A. The left ventricle 24-A is located inside the right shell 1-A, and the right ventricle 24-B is located inside the left shell 1-B.
[0057] The ventricle can be formed in various ways. In one embodiment, please refer to [reference needed]. Figure 1 , Figure 2 and Figure 9 The intelligent bionic heart includes a left ventricular diaphragm 2-A and a right ventricular diaphragm 2-B. The left ventricular diaphragm 2-A is mounted on the right shell 1-A, and the cavity formed between the left ventricular diaphragm 2-A and the right shell 1-A is the left ventricle 24-A. Similarly, the right ventricular diaphragm 2-B is mounted on the left shell 1-B, and the cavity formed between the right ventricular diaphragm 2-B and the left shell 1-B is the right ventricle 24-B.
[0058] In another embodiment, please refer to [reference needed]. Figure 1 , Figure 2 , Figure 14 and Figure 15 The intelligent bionic heart includes a left ventricular soft capsule 25-A and a right ventricular soft capsule 25-B. The left ventricular soft capsule 25-A is installed and closely attached to the right shell 1-A, and the right ventricular soft capsule 25-B is installed and closely attached to the left shell 1-B. The left ventricular soft capsule 25-A itself constitutes the left ventricle 24-A, and the right ventricular soft capsule 25-B itself constitutes the right ventricle 24-B.
[0059] Please refer to the above. Figure 1 , Figure 2 and Figure 16Both the left ventricle 24-A and the right ventricle 24-B have two openings for connecting to artificial blood vessels. The inlet valves include a left ventricular inlet valve 20 and a right ventricular inlet valve 18, and the outlet valves include a left ventricular outlet valve 21 and a right ventricular outlet valve 19. Specifically, the two openings on the left ventricle 24-A are used to connect to the left ventricular common artery 17 and the left ventricular common pulmonary vein 16, respectively. The outlet corresponding to the left ventricular common artery 17 is equipped with the left ventricular outlet valve 21, and the outlet corresponding to the left ventricular common pulmonary vein 16 is equipped with the left ventricular inlet valve 20. Two openings on the right ventricle 24-B are used to connect the right ventricular common vein 14 and the right ventricular pulmonary aortic vessel 15, respectively. The right ventricular common vein 14 is equipped with a right ventricular inlet valve 18, and the right ventricular pulmonary aortic vessel 15 is equipped with a right ventricular outlet valve 19.
[0060] See also Figure 1 , Figure 2 The power system has two push-pull plates connected to each end. One push-pull plate is attached to the left ventricle 24-A, and the other is attached to the right ventricle 24-B. The power system drives the push-pull plates to move in a reciprocating linear motion. When the push-pull plate moves towards the left ventricle 24-A, it pushes the left ventricle 24-A to pump out blood, while the right ventricle 24-B at the other end expands its volume and draws in blood. When the push-pull plate moves towards the right ventricle 24-B, it pushes the right ventricle 24-B to pump out blood, while the left ventricle 24-A at the other end expands its volume and draws in blood. The power system's cyclical movement causes the left ventricle 24-A and right ventricle 24-B to continuously draw in and pump out blood, thus promoting blood circulation in the human body.
[0061] The push-pull plates include a left ventricular push-pull plate 4-A and a right ventricular push-pull plate 4-B. It should be noted that in this embodiment, the left ventricular push-pull plate 4-A is attached to the left ventricular diaphragm 2-A, meaning that the left ventricular push-pull plate 4-A and the left ventricular diaphragm 2-A are close together, but they are not fixedly connected. Similarly, the right ventricular push-pull plate 4-B is close to the right ventricular diaphragm 2-B, but they are not fixedly connected to each other. However, in other embodiments, they may be fixedly connected, which will not be elaborated here.
[0062] Combination Figure 1 and Figure 11In the indicated state, the power system drives the left ventricular push-pull plate 4-A towards the left ventricle 24-A. The left ventricular push-pull plate 4-A pushes the left ventricle 24-A, causing the left ventricle 24-A to pump blood out. At the same time, because the size of the sealed space remains constant, for every volume that the left ventricle 24-A is squeezed out, the right ventricle 24-B will be stretched and expanded by the same amount, causing the right ventricle 24-B to draw in an equal amount of blood.
[0063] Combined Figure 2 and Figure 12 In the illustrated state, similarly, the power system drives the right ventricular push-pull plate 4-B towards the right ventricle 24-B. The right ventricular push-pull plate 4-B compresses the right ventricle 24-B, causing the right ventricle 24-B to pump blood out. Also, because the size of the enclosed space remains constant, for every volume of blood squeezed out of the right ventricle 24-B, the left ventricle 24-A is pulled open, expanding to a volume equal to the volume squeezed out of the right ventricle 24-B, causing the left ventricle 24-A to draw in blood.
[0064] The power system performs reciprocating linear motion in the left-right direction, enabling the intelligent bionic heart to... Figure 1 , Figure 11 The state shown and Figure 2 , Figure 12 The system continuously switches between states, namely, the state of "left ventricle 24-A drawing in blood and right ventricle 24-B pumping out blood" and the state of "left ventricle 24-A pumping out blood and right ventricle 24-B drawing in blood," thus realizing the circulation of blood in the human body.
[0065] The blood volume regulation system is electrically connected to the intelligent control system. The blood volume regulation system is used to regulate the blood supply and demand balance between the left and right ventricles. When the intelligent control system detects an imbalance in the blood supply between the left and right ventricles through the sensor and needs adjustment, it controls the blood volume regulation system to move towards the ventricle with a larger blood pumping volume, squeezing the ventricle with a larger blood pumping volume to reduce its expansion and the amount of blood drawn in and pumped out. When the intelligent control system detects that the blood supply and demand of the human body have reached a balance, it controls the blood volume regulation system to reverse its operation, no longer squeezing the ventricle with a larger blood pumping volume that is being squeezed, or reducing the squeezing of the ventricle with a larger blood pumping volume as needed, so that the blood supply and demand between the left and right ventricles can reach a balance.
[0066] As mentioned above, although the pumping and drawing of blood out of the left and right ventricles are theoretically equal, in practical applications, slight differences in the opening and closing of the valves, as well as differences in each person's weight, blood vessels, and blood pressure, can lead to differences in the total amount of blood pumped out and drawn in by the left and right ventricles after a period of operation. To solve this major problem, the intelligent bionic heart of this application embodiment also includes a blood volume regulation system and sensors. The sensors can be used to detect the blood supply to the left ventricle 24-A and the right ventricle 24-B through the intelligent control system.
[0067] like Figure 3 As shown, when the blood supply to the right ventricle 24-B is greater than that to the left ventricle 24-A, the intelligent control system directs the blood volume regulation system to move towards the right ventricle 24-B, compressing it. When the right ventricle 24-B expands its volume and dilates, due to the compression of the blood volume regulation system, as... Figure 4 As shown, the expansion volume of right ventricular 24-B will decrease, thereby reducing the amount of blood pumped by right ventricular 24-B.
[0068] Similarly, such as Figure 5 As shown, when the blood supply to the left ventricle 24-A is greater than that to the right ventricle 24-B, the intelligent control system directs the blood volume regulation system to move towards the left ventricle 24-A, compressing it. When the left ventricle 24-A expands its volume and dilates, due to the compression of the blood volume regulation system, as... Figure 6 As shown, the expansion volume of the left ventricular 24-A will decrease, thereby reducing the amount of blood pumped by the left ventricular 24-A.
[0069] It should be noted that the sensors can continuously monitor the blood supply to the left ventricle (24-A) and right ventricle (24-B) and upload this data to the intelligent control system. When the sensors provide pressure or flow through the monitoring points at the four ports of the left and right ventricles, and the intelligent control system calculates and detects that the blood supply to the left and right ventricles has reached equilibrium, the intelligent control system promptly controls the blood volume regulation system to reverse its operation. The blood volume regulation system then returns a value as shown in the diagram. Figure 1 , Figure 2 The state shown.
[0070] In the intelligent bionic heart of this application embodiment, sensors are set to detect the blood supply to the left and right ventricles and upload the data to the intelligent control system. When the blood supply to the left and right ventricles is unbalanced, the intelligent control system immediately controls the blood volume regulation system to move to the ventricle with a larger blood supply in the left and right ventricles. This causes the blood volume regulation system to squeeze the ventricle with a larger blood supply, thereby reducing the expansion of the ventricle with a larger blood supply and reducing the amount of blood drawn in and pumped out by the ventricle with a larger blood supply. This balances the blood supply to the left and right ventricles and prevents the intelligent bionic heart from experiencing an imbalance in the blood supply to the left and right ventricles during use, thus making this application safer.
[0071] Optionally, the intelligent control system includes at least a circuit board and chip, software programs, and of course, high-precision algorithms and a large amount of experimental data. The intelligent control system is used to detect the user's body indices through different sensors, including at least: body movement speed, body temperature, respiratory rate, height, and weight.
[0072] It should be noted that the sensors have various functions and models, and are installed inside and outside the housing and at the four ports of this application as needed, and are all electrically connected to the intelligent control system.
[0073] The intelligent control system is used to set the initial number of runs of the power system based on the user's height, weight, and body mass index. It also adjusts the number of runs of the power system in real time based on changes in the user's body movement speed, body temperature, and respiratory rate after use. In other words, it adjusts the number of pumping operations of the left ventricle 24-A and right ventricle 24-B in real time to adapt to the blood supply under different exercise conditions, including when the body temperature rises due to illness and breathing becomes faster.
[0074] For example, a 50 kg adult woman or a 60 kg adult man, at rest, with the heart pumping blood 60 times per minute and each pumping 70 ml of blood, approximately 4200 ml of blood is pumped out of the heart and delivered to various parts of the body per minute. The initial operating frequency of the extension component 6 of the power motor 5, which drives the power system, is 60 times per minute. Of course, the amount of blood pumped by the heart per minute varies for individuals of different weights; the greater the weight, the greater the amount of blood pumped per minute. These settings can be configured during surgery. For example, for a male, the initial pumping frequency is 60 times per minute for a weight of 60 kg, 70 times per minute for a weight of 70 kg, 80 times per minute for a weight of 80 kg, and 90 times per minute for a weight of 90 kg or more. This application designs a pumping volume of 70 ml per cycle. When the intelligent control system senses an increase in body temperature, accelerated breathing, or increased physical activity through sensors, it instructs the motor 5 to either increase its speed (from an initial 60 beats per minute, gradually increasing to a maximum of 100 beats per minute; or from an initial 90 beats per minute, gradually increasing to a maximum of 130 beats per minute) or decrease its speed (from a maximum of 100 or 130 beats per minute, gradually decreasing to 60 or 90 beats per minute), thereby simulating the rhythm and purpose of human heart function. Furthermore, a single product model addresses the compatibility issue for male and female patients of different weights, making the intelligent bionic heart of this embodiment more suitable for the needs of diverse individuals.
[0075] Optionally, the blood volume regulation system includes an regulating motor 7, a screw 8, a fixed guide slide 10, and a squeezing component 9. The regulating motor 7 is connected to the screw 8, the screw 8 is connected to the squeezing component 9, and the fixed guide slide 10 is fixedly installed for the smooth operation of the squeezing component 9. When the intelligent control system detects an imbalance in the blood pumping volume between the left ventricle 24-A and the right ventricle 24-B through the sensor, it controls the regulating motor 7 to rotate, causing the screw 8 to drive the squeezing component 9 to move towards the ventricle with a larger blood pumping volume, so that the squeezing component 9 squeezes the ventricle with a larger blood pumping volume, reducing its expansion and blood pumping volume.
[0076] like Figure 13A and Figure 13B As shown, the adjusting motor 7 is connected to the screw 8 to drive the screw 8 to move linearly in the left and right direction. The extrusion part 9 includes a connecting part and an extrusion part. The connecting part is in the shape of a bent rod. One end of the connecting part is connected to the extrusion part, and the other end of the connecting part passes through one end of the screw 8 and is disposed on the fixed guide slide 10.
[0077] For example, adjusting the motor 7 drives the screw 8 to move to the left. Since one end of the screw 8 is connected to the connecting part, the connecting part will drive the extrusion part to move to the left as well, entering the... Figure 13B The state shown, in conjunction with [see also] Figure 4 The extruder 9 can compress the right ventricle 24-B. Due to the setting of the fixed guide slide 10, the screw 8 and the extruder 9 can maintain a stable direction of movement during the movement process and will not deviate, thereby realizing the stable operation of the blood volume regulation system in the intelligent bionic heart of this application embodiment.
[0078] It should be noted that the blood volume regulation system shown in this illustration is only one type of motor and structure. There are many other types of motors and structures, which will not be described in detail here.
[0079] Optionally, the power system includes a power motor 5, a telescopic component 6, a power guide slide rod 6-A, and a push-pull plate. The power motor 5 is a linear motor that drives the telescopic component 6 to reciprocate in a linear motion. The telescopic component 6 is connected to the push-pull plate and also reciprocates in a linear motion to compress the left ventricle 24-A and the right ventricle 24-B. The power guide slide rod 6-A is used for the smooth operation of the telescopic component 6 and the push-pull plate.
[0080] Please refer to the above. Figure 1 , Figure 2 , Figure 11 , Figure 12 and Figure 23The power system includes a power motor 5, a telescopic component 6, and a power guide slide rod 6-A. The power motor 5 is connected to the power system telescopic component 6 and drives the telescopic component 6 to perform reciprocating linear motion in the left-right direction. The power system also includes a guide slide rod 64. The telescopic component 6 is positioned between two power guide slide rods 6-A to prevent positional displacement of the telescopic component 6 during movement, ensuring the operational stability of the power system in the intelligent bionic heart of this embodiment.
[0081] The two ends of the power system telescopic component 6 are respectively connected to the left ventricular push-pull plate 4-A and the right ventricular push-pull plate 4-B.
[0082] like Figure 1 and Figure 11 In the indicated state, the power motor 5 drives the telescopic component 6 of the power system to move towards the left ventricle 24-A. The left ventricle push-pull plate 4-A compresses the left ventricle 24-A, causing the left ventricle 24-A to pump blood out. At the same time, because the size of the sealed space remains unchanged, the right ventricle 24-B is "stretched" by the right ventricle push-pull plate 4-B, expanding its volume and causing the right ventricle 24-B to draw in blood.
[0083] like Figure 2 and Figure 12 In the illustrated state, similarly, the power motor 5 drives the telescopic component 6 of the power system to move towards the right ventricle 24-B, and the right ventricle push-pull plate 4-B compresses the right ventricle 24-B, causing the right ventricle 24-B to pump blood out. At the same time, because the size of the sealed space remains unchanged, the left ventricle 24-A is "stretched" by the left ventricle push-pull plate 4-A, expanding its volume, causing the left ventricle 24-A to draw in blood.
[0084] The power motor 5 drives the telescopic component 6 of the power system to reciprocate linearly in the left and right directions, enabling the intelligent bionic heart to... Figure 1 , Figure 11 The state shown and Figure 2 , Figure 12 The system continuously switches between the indicated states, specifically between "left ventricle 24-A drawing in blood and right ventricle 24-B pumping out blood" and "left ventricle 24-A pumping out blood and right ventricle 24-B drawing in blood," thus achieving human blood circulation.
[0085] Optionally, the intelligent bionic heart also includes a power supply system, which includes a built-in battery 11, a built-in receiving power coil 26, an external battery 30, and an external transmitting power coil 27. The built-in receiving power coil 26 can be implanted subcutaneously and is electrically connected to the built-in battery 11 and the intelligent control system. The external transmitting power coil 27 is correspondingly positioned inside and outside the human body to supply power to the devices inside the body. The external battery 30 can be integrated with the external circuit board and chip 29 into a module and placed in the pocket of the vest 31 or belt worn outside the human body, and connected to the external transmitting power coil 27 to supply power to the human body. However, the external battery can still be used separately without being integrated, so as to facilitate replacement and charging.
[0086] like Figure 10 As shown, the built-in battery 11, built-in circuit board and chip 12 are located on one side of the power system to receive external charging power and simultaneously power the various components inside the intelligent bionic heart shell.
[0087] Please refer to the above. Figure 17 and Figure 18 The external battery 30 and the external power transmitting coil 27 are electrically connected and are set together on the outside of the shell of the intelligent bionic heart. The internal power receiving coil 26 and the internal battery 11 are electrically connected. The internal power receiving coil 26 and the external power transmitting coil 27 correspond to each other. The power of the external battery 30 is sent to the internal power receiving coil 26 through the external power transmitting coil 27, and then to the internal battery 11.
[0088] like Figure 19 As shown, the outer vest 31 includes a vest zipper, vest pockets, and pocket zippers. An external battery 30, an external power transmission coil, an external circuit board, and a chip 29 can be integrated into a small module, installed in a pocket, and can maintain a stable connection with the intelligent bionic heart inside the human body for a long time, continuously charging the built-in rechargeable battery to power the components inside the intelligent bionic heart shell.
[0089] Optionally, the intelligent bionic heart also includes a communication system, which includes a built-in communication module, an external communication module, and an external early warning device 28. Both the communication system and the power supply system are electrically connected to the intelligent control system, and the built-in and external parts of the communication system and the power supply system are connected wirelessly.
[0090] like Figure 18As shown, the external warning device 28, external battery 30, external power transmission coil, external circuit board, and chip 29 are integrated into the same module for easy portability. The operating information of the intelligent bionic heart is sent to the external warning device 28 via the built-in communication module and the external communication module. When the intelligent bionic heart's operating status is abnormal, the external warning device 28 issues an alarm to remind the user to check or replace the battery in a timely manner.
[0091] Optionally, the left ventricle 24-A, the right ventricle 24-B, the artificial blood vessel, the ingress valve, and the egress valve—all components that come into contact with blood—are made of biocompatible materials. The surfaces of all components in the intelligent bionic heart that come into contact with blood can still be coated with biocompatible materials.
[0092] In this embodiment, all components that come into contact with blood are made of biocompatible materials, or all surfaces of components that come into contact with blood are coated with biocompatible materials. By doing so, adverse reactions between the intelligent bionic heart and the human body can be avoided, further improving safety.
[0093] Optionally, the intelligent bionic heart further includes a support frame 3 and a locking ring. The support frame 3 is used to fix the power system and the blood volume regulation system. The locking ring is used to fix and connect the tube opening to the artificial blood vessel and the ingress valve and the egress valve, and to fix and connect the shell to the left ventricle 24-A and the right ventricle 24-B.
[0094] It should be noted that the buckle ring has multiple models, such as the buckle ring 13 connecting the blood vessel and the shell, the buckle ring 22 connecting the left shell and the middle shell, and the buckle ring 23 connecting the right shell and the middle shell.
[0095] Optionally, the housing is a multi-component assembly. After the internal components are installed, the multiple components are combined by snap-fit rings or welding to form a sealed whole. Alternatively, the housing is a complete housing with an opening, and the opening is sealed with a back cover after the internal components are installed.
[0096] like Figure 10 As shown, a support frame 3 is set in the middle of the intelligent bionic heart shell, and the power system and blood volume regulation system are both installed on the support frame 3.
[0097] like Figure 7As shown, the housing can be composed of three parts: left, right, and middle. The support frame 3 is located in the middle housing. After the power system, blood volume regulation system, built-in battery 11, built-in circuit board, and chip 12 are installed onto the support frame 3, the left housing 1-B is assembled to the middle housing via the connecting buckle 23, and the right housing 1-A is assembled to the middle housing via the connecting buckle 22. This allows for the following... Figure 8 The state shown is as follows, as it appears from the outside. Figure 20 , Figure 24 The status shown. Please refer to further details. Figure 1 and Figure 16 The artificial blood vessel is detachably connected to the shell via a connecting buckle. This structure is simple, easy to install, and allows for quick disassembly for user replacement.
[0098] In another embodiment, the housing can be a single, integral component with an opening at one end for installing internal components. After installation, the components are sealed using a rear cover. In this embodiment, the overall structure of the housing is more stable.
[0099] This application also provides a method for operating an intelligent bionic heart, applied to the aforementioned intelligent bionic heart, the method comprising:
[0100] It acquires information on the operation of the intelligent bionic heart and various movements and functions of the user's body.
[0101] Based on the intelligent bionic heart's operating information and the user's various movements and operating information, it prompts and controls the operating status of the power system and blood volume regulation system.
[0102] The intelligent bionic heart's operational information includes at least the blood supply information for the left and right ventricles. When an imbalance in blood supply between the left and right ventricles is detected and adjustment is needed, the blood volume regulation system is controlled to move towards the ventricle with the greater blood supply, compressing it to reduce its expansion and the amount of blood drawn in and pumped out. When the intelligent control system detects that the body's blood supply and demand have reached balance, it controls the blood volume regulation system to reverse its operation, ceasing to compress the ventricle with the greater blood supply, or reducing compression of the ventricle as needed, to achieve a balance in blood supply and demand between the left and right ventricles.
[0103] The intelligent bionic heart's operational information can also include the user's physical index information such as the speed of physical movement, body temperature, and respiratory rate. Based on the physical index, the reciprocating speed of the power system can be adjusted to increase or decrease the number of times the left ventricle 24-A and right ventricle 24-B pump blood, so as to adapt to the blood supply of the human body under different exercise conditions.
[0104] It should be noted that the illustrations shown in this application are for ease of understanding only. In actual manufacturing and use, the position, shape, size, proportion, and structural form of each component in the illustrations should be adjusted according to actual needs during manufacturing (unless otherwise specified). For example (but not limited to) the thickness and position of the main blood vessel and the tube opening, the shape, size and position of the inlet and outlet valves, the circuit board and chip, the structural form of the housing, and the shape, size and position of each component, etc. For example, in the illustrations, the built-in battery, circuit board and chip are set inside the housing, but in actual manufacturing, they can also be set outside the housing as needed.
[0105] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
Claims
1. An intelligent bionic heart, characterized in that, The intelligent bionic heart includes: a shell, a left ventricle, a right ventricle, an ingress valve, an egress valve, artificial blood vessels, a power system, a blood volume regulation system, an intelligent control system, and sensors; The left and right ventricles are located on the left and right sides of the shell, respectively. Each of the left and right ventricles has two openings, and the inlet valve and the outlet valve are respectively located at the openings. There are four artificial blood vessels, one end of which is connected to the four openings of the left and right ventricles, and the other end is connected to the human aorta, the pulmonary aorta, the left atrial incision, and the right atrial incision, respectively. The power system has two push-pull plates connected to each end, one attached to the left ventricle and the other to the right ventricle. The power system drives the push-pull plates in a reciprocating linear motion. When the push-pull plate moves towards the left ventricle, pushing and pumping blood out of the left ventricle, the right ventricle expands its volume and draws in blood. Conversely, when the push-pull plate moves towards the right ventricle, pushing and pumping blood out of the right ventricle, the left ventricle expands its volume and draws in blood. This cyclical motion of the power system causes the left and right ventricles to continuously draw in and pump out blood, thus promoting blood circulation in the body. The blood volume regulation system is electrically connected to the intelligent control system. The blood volume regulation system is used to regulate the blood supply and demand balance between the left and right ventricles. When the intelligent control system detects an imbalance in the blood supply between the left and right ventricles through the sensor and needs adjustment, it controls the blood volume regulation system to move towards the ventricle with a larger blood pumping volume, squeezing the ventricle with a larger blood pumping volume to reduce its expansion and the amount of blood drawn in and pumped out. When the intelligent control system detects that the blood supply and demand of the human body have reached a balance, it controls the blood volume regulation system to reverse its operation, no longer squeezing the ventricle with a larger blood pumping volume that is being squeezed, or reducing the squeezing of the ventricle with a larger blood pumping volume as needed, so that the blood supply and demand between the left and right ventricles reach a balance. The blood volume adjustment system includes an adjustment motor, a screw, a fixed guide slide, and an extrusion component. The adjustment motor is connected to the screw, the screw is connected to the extrusion component, and the fixed guide slide is fixedly installed for the smooth operation of the extrusion component. The sensor is used to detect the blood supply to the left and right ventricles by the pressure or flow provided by the monitoring points at the four tube openings of the left and right ventricles and upload the data to the intelligent control system. When the intelligent control system detects an imbalance in the blood pumping volume between the left and right ventricles through the sensor, it controls the regulating motor to rotate, causing the screw to drive the extruder to move towards the ventricle with a larger blood pumping volume, so that the extruder squeezes the ventricle with a larger blood pumping volume, reducing its expansion and blood pumping volume.
