Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a power supply device, a defibrillator and a defibrillator system. Background Art

[0002] Implantable Cardioverter Defibrillator (ICD) is used to provide anti-tachycardia pacing pulses and high-voltage defibrillation pulses. In order to improve the clinical symptoms of ICD, the cardiac contractility modulation (CCM) function is integrated into the ICD. CCM technology implants the stimulation electrode into the patient's right ventricle through minimally invasive surgery, and releases electrical stimulation during the absolute refractory period of the heart beat to increase the contractility of the local myocardium. Combining CCM with ICD forms a medical device that integrates anti-arrhythmia and heart failure treatment.

[0003] Single CCM devices are powered by a single battery. This power supply method uses high energy density, long life lithium batteries as energy to ensure that the device can operate stably for a long time in the patient's body. Lithium batteries have been widely used in implantable medical devices due to their high energy density and long cycle life.

[0004] For ICD batteries with integrated CCM functions, they need to have high driving capabilities and long battery life. For example, high-voltage defibrillation requires instantaneous release of a large amount of energy, and continuous monitoring and on-demand treatment require the battery to have a long service life. However, it is difficult to strike a balance between the two with a single battery power supply, resulting in performance limitations or shortened lifespan of the device in applications.

[0060] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0061] Defibrillators include wearable and implantable types. Among them, implantable defibrillator ICD is an electronic device that can be implanted in the patient's body to continuously monitor the patient's heart rhythm. When rapid ventricular arrhythmias are detected, such as ventricular tachycardia or ventricular fibrillation, it automatically releases electric shock for defibrillation or cardioversion to restore the patient's normal heartbeat and avoid sudden death.

[0062] ICD with cardiac contractility regulation therapy function CCM combines the functions of ICD and CCM to provide patients with comprehensive cardiac protection, which can prevent sudden cardiac death and improve heart failure symptoms. ICD identifies malignant arrhythmias such as ventricular tachycardia or ventricular fibrillation by monitoring the patient's ECG signals. When arrhythmias are detected, ICD will release electric shock energy for defibrillation or cardioversion to restore the patient's normal heartbeat. CCM emits electrical stimulation during specific periods of cardiac contraction of the myocardium, for example, during the absolute refractory period, and the electrical stimulation will not change the patient's heart rhythm. Through a series of signal pathways, the calcium regulation state of the myocardium is improved, the contractility of the myocardium is enhanced, and thus the cardiac function of patients with heart failure is improved.

[0063] A single CCM is powered by a single battery. A single battery helps reduce the size of the CCM, making it easier to implant in the patient and reducing the impact on the patient's daily life. In addition, a single-battery system is relatively simple, which can reduce the connection and failure points between batteries.

[0064] Although the life of a single ICD battery is long, as the battery runs out, the ICD needs to be replaced, increasing the patient's medical risks and costs. In addition, in order to extend the battery life and improve the driving ability, the size and weight of the battery need to be increased. However, in implantable medical devices, the increase in size and weight will limit the patient's mobility, resulting in performance limitations or shortened life of the device in application.

[0065] To solve the above problems, see Figure 1 Some embodiments of the present application provide a power supply device, including:

[0066] The dual-battery power supply module includes a first battery and a second battery, wherein the first battery is a non-rechargeable battery, for example, a lithium-silver barium pentoxide battery, which has a high energy density and can provide a large amount of energy in a short time to meet the high energy requirements during cardioversion and defibrillation. The second battery is a rechargeable battery, for example, a lithium-iodine battery, which has a long service life, supports repeated charging, and can provide a stable power supply. The first battery outputs a first voltage, and the second battery outputs a second voltage.

[0067] The second battery is provided with a wireless charging interface, which refers to a wireless charging receiving coil integrated inside or outside the battery. The coil is coupled with a wireless charging transmitter, for example, a transmitting coil in a charging pad or a charging base, through electromagnetic induction, magnetic field resonance or other wireless methods, thereby realizing the transmission of electrical energy.

[0068] The first battery and the second battery are connected to the first end of the power supply switching circuit, that is, the power supply switching circuit is connected to the non-rechargeable battery and the rechargeable battery at the same time. The power supply switching circuit selects a suitable battery for power supply according to the battery status, such as power level and health status, through an intelligent switching mechanism.

[0069] The second end of the power supply switching circuit is connected to a voltage stabilizing circuit to output a third voltage through the voltage stabilizing circuit. The voltage stabilizing circuit outputs an unstable voltage from the first end. It can be understood that the unstable voltage can come from the first battery or the second battery, but is converted into a stable third voltage output through the voltage stabilizing circuit.

[0070] The third end of the power supply switching circuit is connected to the first boost circuit, through which the fourth voltage is output. The first boost circuit boosts the input voltage to a higher voltage level to generate the fourth voltage. The fourth voltage is used in situations where a high voltage output is required, such as cardioversion and defibrillation.

[0071] When the remaining energy of the second battery is sufficient, the power supply switching circuit controls the second battery to supply power to the voltage stabilizing circuit and the first boosting circuit; when the remaining energy of the second battery is insufficient, the power supply switching circuit controls the first battery to supply power to the voltage stabilizing circuit and the first boosting circuit. By intelligently switching the power supply, it is possible to seamlessly transition to the backup power supply when the second battery is low on power, thereby avoiding downtime due to battery exhaustion. An ICD with CCM can be powered by both rechargeable and non-rechargeable batteries to ensure that the ICD can work continuously and stably.

[0072] Based on the above power supply device, see Figure 2 Some embodiments of the present application also provide a defibrillator, including: a first unit, a second unit and a third unit. The first unit includes the power supply device and a charging module, and the charging module charges the second battery through the wireless charging interface on the second battery.

[0073] The second unit includes a first functional module, a second functional module, a third functional module and a fourth functional module, wherein the first functional module is configured to send bidirectional pulses according to the area to be defibrillated, and adopt the bidirectional pulses as a treatment method to provide cardiac contractility regulation treatment. The area to be defibrillated is the right ventricular septum area of ​​the patient's heart. During the absolute refractory period of cardiac contraction, the defibrillator will release an electrical stimulation signal to regulate the cardiac contractility.

[0074] The second functional module is configured to send anti-tachycardia electric pulses and fixed-frequency pulses according to the area to be defibrillated. The electric pulses sent according to the area to be defibrillated are used to provide anti-tachycardia treatment when the patient has ventricular tachycardia, that is, when the patient's heart rate exceeds the ventricular tachycardia threshold, and send pulses to the myocardium through the electrode wire to capture the myocardium and inhibit tachycardia. Fixed-frequency pulses are sent according to the area to be defibrillated for testing, and a certain frequency, for example, 50Hz frequency pulses are issued to capture the myocardium and induce myocardial fibrillation.

[0075] The third functional module is configured to send defibrillation pulses according to the area to be defibrillated, and is used to send low-energy cardioversion pulses and high-energy defibrillation pulses to the myocardium. The defibrillation pulses are used to convert the heart to normal rhythm when ventricular tachycardia or ventricular fibrillation occurs.

[0076] The fourth functional module is configured to send electric pulses according to the area to be defibrillated to provide bradycardia treatment, that is, when the patient's heart rate is lower than a set threshold, electric pulses are sent to the myocardium through the electrode wire to capture the myocardium.

[0077] The power supply device provides power to the first functional module, the second functional module, the third functional module and the fourth functional module. Figure 3 , wherein the first voltage powers the third functional module. In some embodiments, the first functional module includes a first energy storage capacitor and a first charge and discharge switch group, the second functional module includes a second energy storage capacitor and a second charge and discharge switch group, and the third functional module includes a third energy storage capacitor and a third charge and discharge switch group.

[0078] Among them, the third energy storage capacitor is charged by the first voltage, that is, the voltage driving current output by the first battery. The high-voltage pulse energy storage capacitor provides high-power charging of more than 10W during the charging process, which can ensure the charging speed of the energy storage capacitor. The typical value of the energy of the charged high-voltage pulse capacitor is 40J.

[0079] The third charge and discharge switch group is powered by a third voltage, that is, a voltage driving current output by the voltage stabilizing circuit. The third voltage output is 15V, which is used to control the charge and discharge switch group with a high-voltage defibrillation pulse.

[0080] The first charge and discharge switch group and the second charge and discharge switch group are powered by a fourth voltage, that is, a voltage drive current output by the first boost circuit. The typical value of the fourth voltage is 8V, which provides a high voltage level to the first functional module and the second functional module.

[0081] The second battery is connected to the second boost circuit to output a fifth voltage, wherein the voltage output of the second battery is boosted by the second boost circuit. The first charge and discharge switch group and the second charge and discharge switch group drive the current to charge through the fifth voltage, and the fifth voltage also charges the third energy storage capacitor within a fixed time, and can charge the pulse capacitor at a power of about 0.1W.

[0082] The defibrillator also includes a main control module, which is connected to the first unit and the second unit and is configured to receive the acquired data of the first unit and the second unit and generate instructions according to the acquired data. The main control module is used to collect information including electrode lead impedance, intracavitary electrical signal perception, motion acquisition, magnetic field detection, temperature detection, battery power monitoring, etc., and run software and algorithms to make logical judgments based on various monitoring information, control dual battery power supply selection, release pacing pulses, CCM treatment pulses, ATP pulses, defibrillation pulses, etc., and is also responsible for controlling the data transmission and reception of Bluetooth wireless communication and near-field wireless communication.

[0083] In order to flexibly control the power supply source, in some feasible embodiments, the remaining power of the second battery is obtained; if the remaining power is less than or equal to the first power threshold, the power supply switching circuit is controlled to control the power supply switching circuit so that the first battery supplies power to the voltage stabilizing circuit and the first boosting circuit; if the power energy is greater than the power threshold, the second battery is kept supplying power to the voltage stabilizing circuit and the first boosting circuit; if the remaining power is greater than or equal to the second power threshold, the power supply switching circuit is controlled to control the power supply switching circuit so that the second battery supplies power to the voltage stabilizing circuit and the first boosting circuit, and the second power threshold is greater than the first power threshold; if the power energy is less than the second power threshold and greater than the first power threshold, the first battery is kept supplying power to the voltage stabilizing circuit and the first boosting circuit.

[0084] The remaining power of the second battery can be obtained through a power monitoring module, wherein the second unit also includes a power monitoring module, and the power monitoring module is configured to monitor the operating voltage of the first battery and the second battery to output the remaining power of the first battery and the second battery.

[0085] See also Figure 4 When the battery power of the second battery drops below the first power threshold, the main control module will detect this state. This threshold is set to a point earlier than before the second battery is completely exhausted to ensure that the system has enough time to switch to the backup power supply. The main control module sends an instruction to the power supply switching circuit to control it to switch the power supply from the second battery to the first battery. At this time, the first battery starts to supply power to the voltage stabilizing circuit and the first boosting circuit.

[0086] When the remaining energy of the second battery is sufficient, that is, the remaining power is higher than the second power threshold, the power supply switching circuit controls the second battery to directly supply power to the voltage stabilizing circuit and the first boosting circuit, because the second battery is rechargeable and has a higher energy density.

[0087] When the second battery is charged through the wireless charging interface and the power level of the second battery is restored to a level higher than the second power threshold, the main control module will detect this state again. The main control module sends an instruction to the power supply switching circuit to control it to switch the power supply from the first battery back to the second battery, and the system resumes using the rechargeable battery as the main power source.

[0088] In order to improve the charging efficiency of the third functional module, namely, defibrillation, shorten the time for charging the high-voltage pulse capacitor with the first voltage generated by the first battery, and consume the battery capacity of the first battery as little as possible, the high-voltage pulse capacitor is charged with the fifth voltage generated by the second battery regularly, and the energy of the high-voltage pulse capacitor is charged to a typical value of 10 J. In addition, the ICD capacitor needs to be regularly charged to maintain the capacitor, and the fifth voltage generated by the second battery can also be used to charge the high-voltage pulse capacitor.

[0089] See again Figure 2 In some embodiments, the second unit further includes an impedance monitoring module and a sensing module.

[0090] See also Figure 5 , Figure 6 The third unit includes a wire interface module, which includes four wire interfaces, namely a first ventricular channel, namely the first channel (interface), a second ventricular channel, namely the second channel (interface), and a defibrillation channel, namely the third channel (interface).

[0091] The impedance monitoring module is connected to the lead interface module through the electrode lead, and is configured to monitor the electrode impedance of the electrode lead, determine whether the implantation of the electrode lead is stable, and assist in determining whether electrode dislocation occurs.

[0092] The sensing module is connected to the wire interface module through the electrode wire, and is configured to obtain the electrical signal of the area to be defibrillated of the electrode wire, convert the electrical signal into a digital signal, and transmit the digital signal to the main control module; a perception threshold judgment circuit is provided in the sensing module, and the perception threshold judgment circuit is configured to generate a logical judgment result, and transmit the logical judgment result to the main control module.

[0093] The sensing module is used to collect the intracavitary electrocardiogram signals of the electrode wire. On the one hand, it converts the analog electrical signals into digital signals and transmits them to the main control module. On the other hand, the perception threshold judgment circuit transmits the logical judgment results of the perception to the main control module. The main control module collects the electrical signals output by the sensing module in real time as the basis for providing various treatments.

[0094] Wherein, in some embodiments, the first channel and the second channel are connected to the impedance monitoring module, the sensing module, the first functional module, the second functional module, the third functional module and the fourth functional module, and are used to connect to the electrode wires in the ventricles, for example, the left ventricle (first subsection) and the right ventricle (second subsection) to monitor the electrical activity of the ventricles. For the CCM function, the first channel is used to transmit pulsed electrical stimulation for regulating cardiac contractility, which is released during the absolute refractory period of the heartbeat to enhance the contractility of the myocardium, thereby improving the cardiac function of patients with heart failure. The first channel and the second channel can also be used for ventricular pacing to correct ventricular arrhythmias or maintain an appropriate ventricular rate.

[0095] The third channel is connected to the sensing module and the third functional module, and is used to connect the defibrillation electrode wires, which can deliver high-energy electric shocks to terminate arrhythmias such as ventricular fibrillation or ventricular flutter. When the ICD detects these arrhythmias, it will deliver high-energy electric shocks through the defibrillation channel to restore the normal rhythm of the heart.

[0096] See again Figure 5 In some embodiments, the wire interface module further includes an atrial channel, i.e., a fourth channel (interface), and the atrial channel does not affect the operation of the first functional module, the second functional module, the third functional module, and the fourth functional module. The fourth channel is used to connect to the electrode wire in the atrium to monitor the electrical activity of the atrium. When necessary, the fourth channel can also be used for atrial pacing to correct atrial arrhythmias or maintain an appropriate atrial rate. The atrial channel is connected to the impedance detection module, the sensing module, and the fourth functional module.

[0097] See again Figure 2 In some embodiments, the first unit further includes: a communication module, the communication module may be a Bluetooth wireless communication module or a near field wireless communication module, the Bluetooth wireless communication module is a short-range wireless communication technology that can achieve fast and flexible data exchange between devices. The near field wireless communication module, for example, NFC, that is, near field communication technology is a short-range wireless communication technology used for close-range data exchange between devices.

[0098] The temperature detection module is used to detect the operating temperature of the defibrillator. When monitoring the operating temperature of the device, the temperature detection module will adjust its monitoring sampling rate according to different working modes and states. During the wireless charging process of the device, the temperature of the device may rise due to the conversion of electrical energy into thermal energy. Therefore, in order to improve the accuracy and timeliness of temperature monitoring, the monitoring sampling rate of the temperature detection module will be set higher during wireless charging.

[0099] Increasing the monitoring sampling rate allows more temperature detections to be performed in a shorter time, and the temperature change trend can be captured more quickly. This protects the defibrillator from overheating and ensures the safety and stability of the wireless charging process. The temperature detection module can also have an intelligent algorithm that can dynamically adjust the sampling rate based on the real-time monitored temperature data. For example, when the temperature rises rapidly or approaches the safety threshold of the device, the sampling rate is automatically increased to track temperature changes more accurately; when the temperature is relatively stable, the sampling rate can be appropriately reduced to save energy and extend the life of the device.

[0100] The motion monitoring module is used to track and record the amount of activity and posture maintenance time of patients with implanted pacemakers.

[0101] The magnetic field detection module is used to monitor the impact of external magnetic fields on implanted devices, including changes in the magnetic field when a small magnet approaches and the magnetic field strength in a strong magnetic field environment such as an MRI (magnetic resonance imaging) instrument. These magnetic fields can interfere with the normal operation of the implanted device. The magnetic field detection module can timely monitor and identify changes in the external magnetic field to ensure the safety and effectiveness of the implanted device. When a strong magnetic field is detected, the magnetic field detection module can trigger the buzzer alarm module to remind the patient to stay away from potentially dangerous environments, thereby reducing unnecessary risks.

[0102] The buzzer alarm module is a sound alarm device that is used to sound an alarm under certain conditions, such as when the defibrillator is exposed to a strong magnetic environment or when the patient has an abnormal heart rate. The buzzer alarm module can attract the patient's attention through sound alarms, reminding them to pay attention to the current abnormal situation and take corresponding countermeasures.

[0103] For power supply of other components, the second voltage driving current output by the second battery can be used to power the main control module, communication module, temperature detection module, motion monitoring module, magnetic field detection module, buzzer alarm module, impedance monitoring module and sensing module.

[0104] Based on a defibrillator as described above, see Figure 7 Some embodiments of the present application also provide a defibrillator system, including: a defibrillator and a first terminal connected to the defibrillator, a magnet, a charging device, and a programming device. The first terminal is a dedicated remote follow-up terminal, which refers to a dedicated terminal with a remote follow-up function. The device and the defibrillator complete wireless communication regularly, receive basic information, event statistics, alarm information, etc. of the defibrillator operation, and send it to a server.

[0105] Magnets are used to non-invasively activate certain functions of the defibrillator, such as turning on communication mode or triggering tests, enhancing the flexibility and convenience of the system.

[0106] Since the defibrillator needs to work in the patient's body for a long time, the charging device provides non-invasive wireless charging to ensure uninterrupted power supply to the defibrillator, thereby extending the service life of the device and reducing the number of frequent surgeries to replace batteries.

[0107] The programming device allows medical personnel to perform in-depth telemetry, parameter setting, program change and control of the defibrillator through wireless communication, ensuring that the defibrillator can be personalized according to the patient's specific condition and treatment needs.

[0108] It is understandable that a second terminal is also included, which can be a terminal device with Bluetooth technology, such as a tablet, mobile phone and other devices. The second terminal serves as a user interface, allowing patients or medical staff to connect to the defibrillator via Bluetooth technology to perform simple data viewing or preliminary setting adjustments.

[0109] The defibrillator is connected to the first terminal, the second terminal, the charging device and the programming device through a Bluetooth wireless communication module. For the programming device, when performing certain high-precision operations, higher safety and shorter distance control are required. Therefore, the defibrillator can also be used to communicate wirelessly with the external programming device through a near-field wireless communication module. By using the near-field wireless communication module, the accuracy and safety of data transmission can be ensured, while avoiding potential interference or misoperation.

[0110] It can be seen from the above technical solutions that the present application provides a power supply device, a defibrillator and a defibrillator system, wherein the defibrillator includes a power supply device, a charging module, a first functional module, a second functional module, a third functional module and a wire interface module. Through the cooperation of the first functional module, the second functional module and the third functional module, cardiac contractility regulation therapy pulses can be provided to achieve defibrillation while having cardiac contractility regulation therapy functions; and the dual battery power supply module of the power supply device can provide power and charging for the functional modules to solve the problem of performance limitation or shortened life of ICD with integrated CCM function in application.

[0111] Similar parts between the embodiments provided in this application can be referenced to each other. The specific implementation methods provided above are only a few examples under the general concept of this application and do not constitute a limitation on the protection scope of this application. For those skilled in the art, any other implementation methods expanded based on the scheme of this application without creative work belong to the protection scope of this application.
