Description

Technical Field

[0001] This invention belongs to the field of medical devices, and in particular relates to a defibrillation system. Background Technology

[0002] Cardiac arrest refers to the sudden cessation of the heart's pumping function, the disappearance of arterial pulsation and heart sounds, and severe ischemia and hypoxia in vital organs (such as the brain), leading to death. This unexpected and sudden death is medically known as sudden cardiac death. Sudden cardiac death caused by cardiac arrest is characterized by rapid onset, rapid progression, and severe symptoms. Furthermore, 80% of cases occur outside of hospitals, making resuscitation difficult. The sudden deaths of these patients (a significant portion of whom are young and middle-aged adults) cause substantial losses to families and society, and represent a serious threat to public health.

[0003] In reality, many acute conditions can escalate into cardiac arrest, such as electric shock, drowning, suffocation, heart disease, hypoglycemia, electrical wire injuries, heatstroke, and shock. The most common arrhythmia during cardiac arrest is ventricular fibrillation (VF). If not terminated promptly, the patient may die within minutes of onset; for every minute of delay, the success rate of resuscitation decreases by 7% to 10%. Currently, the only effective clinical method for terminating ventricular fibrillation is defibrillation.

[0004] A defibrillator is a highly intelligent and automated defibrillation device that integrates physicians' ability to identify life-threatening arrhythmias into its algorithms. It uses a low-energy, high-efficiency biphasic waveform to deliver a defibrillation shock, making it safe for general public use. Most existing defibrillators, for portability, rely on batteries as their power source and spend the majority of their time in standby mode. However, as a device with high reliability requirements, defibrillators periodically wake up to run self-test programs and indicate the device's status. These processes consume battery power; statistically, the vast majority of battery energy is consumed during self-test programs and standby.

[0005] In order to reduce energy consumption, defibrillators usually only perform necessary timed wake-up self-test procedures or network data communication at set time points. Outside of these time periods, remote wake-up is not possible. However, in reality, users expect to control the device to remotely wake up to perform self-tests or obtain device information. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a defibrillation system.

[0007] To achieve the objectives of this invention, the technical solution adopted is as follows:

[0008] A defibrillation system includes a transmitting device and a receiving device;

[0009] The transmitting device emits electromagnetic waves to the receiving device. The electromagnetic waves include energy and data information. The receiving device receives the energy and begins to work. Part of the energy is used directly by the defibrillator circuit.

[0010] The receiving device also parses the data information, and the management component makes decisions based on the received data information.

[0011] Furthermore, the receiving device receives energy and begins to operate. Part of the energy is used directly by the defibrillator circuit, while the remaining energy is managed by the management component and stored in the energy storage component.

[0012] Furthermore, the transmitting / receiving device is a near-field communication transmitting device.

[0013] Furthermore, the transmitting device includes a generating component, which includes a first antenna and a data encoding / decoding integrated component;

[0014] The receiving device includes a receiving component, a management component, and a defibrillator circuit; the receiving component includes a second antenna and a data encoding / decoding integrated component.

[0015] Furthermore, the first antenna is electrically connected to the data encoding / decoding integrated component; the projection of the first antenna along a direction perpendicular to the defibrillation circuit at least partially falls outside the defibrillation circuit.

[0016] Furthermore, the generating component transmits electromagnetic waves to the receiving component via the first antenna; the receiving component receives the electromagnetic waves via the second antenna.

[0017] When the user does not need to remotely wake up the defibrillator, the electromagnetic waves received by the receiving device contain energy. The receiving component receives the energy and starts working, converting the electromagnetic wave energy into electrical energy. Part of the electrical energy is used by the defibrillator circuit to indicate the device status information when the defibrillator is in standby mode. The remaining electrical energy is managed by the management component and stored in the optional energy storage component.

[0018] Furthermore, when the defibrillator circuit requires more energy, the management component draws energy from the optional energy storage component to power the defibrillator circuit.

[0019] Furthermore, when a user wishes to perform a remote wake-up operation, the transmitting device encodes the data information through a data encoding and decoding integrated component and transmits the data information to the receiving component through the first antenna;

[0020] The electromagnetic waves received by the receiving device include data information. The integrated data encoding and decoding component in the receiving component decodes the data information. The management component decides whether to wake up the defibrillator circuit based on the received data information.

[0021] Furthermore, once the defibrillator circuit is activated, the management component transmits the processed data to the defibrillator circuit, which then makes decisions about its subsequent operation based on the data.

[0022] Furthermore, the first antenna also includes a matching circuit, one end of which is connected to the integrated data encoding and decoding component, and the other end of which is connected to the first antenna; the second antenna also includes a matching circuit, one end of which is connected to the integrated data encoding and decoding component, and the other end of which is connected to the second antenna.

[0023] Furthermore, the transmitting device is installed inside the equipment storing the defibrillator, which can be an AED chassis or a portable bag; the receiving device is the defibrillator.

[0024] Furthermore, the transmitter can be powered externally or by a battery.

[0025] Furthermore, the defibrillator can send data information to a transmitting device, which then remotely transmits the information to the user via a network.

[0026] Furthermore, the network includes 4G, 5G, WIFI, and wired connections.

[0027] The beneficial effect of this invention is that, compared with the prior art, this invention uses the energy transmitted by NFC during normal operation to cope with the energy consumption of the defibrillator's periodic self-test. The extra energy of NFC can be used for status display during standby, or the energy can be stored for use by the defibrillator, such as for the defibrillator's short-term self-test program, thereby reducing the defibrillator's battery consumption.

[0028] This invention transmits data to the defibrillator via NFC, thereby enabling data communication with the chassis. This allows the defibrillator to be woken up at any time without consuming the defibrillator's battery power, and to perform self-tests, network connections, and other actions.

[0029] Figure 1 This is a schematic diagram of the defibrillation system structure described in this invention;

[0030] Figure 2 This is a schematic diagram of the energy transfer process;

[0031] Figure 3 This is a diagram illustrating the remote wake-up process. Detailed Implementation

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of this application.

[0033] like Figure 1 As shown, a defibrillation system mainly includes a transmitting device 101 and a receiving device 102.

[0034] The transmitting device 101 mainly includes a generating component 301, which includes a first antenna and a data encoding / decoding integrated component.

[0035] The first antenna also includes a matching circuit, one end of which is connected to the integrated data codec assembly, and the other end is connected to the first antenna. The first antenna is electrically connected to the integrated data codec assembly; the projection of the first antenna along a direction perpendicular to the defibrillator circuit 305 at least partially falls outside the defibrillator circuit 305. This reduces the shielding and attenuation caused by the defibrillator circuit to the first antenna, and the weakening of the first antenna's performance, ensuring the antenna's radiation and reception performance without requiring a large investment of energy.

[0036] The receiving device 102 mainly includes a receiving component 302, a management component 303, and a defibrillator circuit 305. The receiving component 302 includes a second antenna and a data encoding / decoding integrated component.

[0037] The second antenna also includes a matching circuit, one end of which is connected to the integrated data encoding and decoding component, and the other end is connected to the second antenna.

[0038] Energy storage component 304 is an optional component. Energy storage component 304 can be a backup battery.

[0039] Transmitting device 101 transmits electromagnetic waves to receiving device 102. These electromagnetic waves include energy and data information. Receiving device 102 receives the energy and begins operation. Part of the energy is directly used by the defibrillator circuit 305, while the remaining energy is managed by management component 303, for example, stored in energy storage component 304. Receiving device 102 also analyzes the data information, and management component 303 makes decisions based on the received data information.

[0040] like Figure 2 As shown, the transmitting device 101 is installed inside the device 103 that houses the defibrillator, which can be an AED enclosure or a portable case, etc. Figure 202 shows the direction of energy transmission.

[0041] The transmitter 101 can be powered externally or by battery.

[0042] The generating component 301 transmits electromagnetic waves to the receiving component 302 via the first antenna; the receiving component 302 receives the electromagnetic waves via the second antenna.

[0043] The electromagnetic waves received by the receiving device 102 include energy. The receiving component 302 receives the energy and begins to operate, converting the electromagnetic wave energy into electrical energy. The electrical energy is first used by the defibrillator circuit 305, and the remaining electrical energy is managed by the management component 303, which can optionally store the electrical energy in the optional energy storage component 304. When the defibrillator circuit 305 requires more energy, the management component 303 obtains energy from the optional energy storage component 304 to supply the defibrillator circuit 305.

[0044] like Figure 3 As shown, the transmitting device 101 is installed inside the device 103 that houses the defibrillator. The receiving device 102 is specifically the defibrillator. Figure 201 shows the data transmission direction, Figure 202 shows the energy transmission direction, and Figure 203 shows the data reception direction.

[0045] The transmitting device 101 transmits data information, encodes the data information through a data encoding and decoding integrated component, and then transmits it to the receiving component 302 through the first antenna.

[0046] The electromagnetic waves received by the receiving device 102 include data information. The data encoding and decoding integrated component in the receiving component 302 decodes the data information. Based on the received data information, the management component decides whether to wake up the defibrillator circuit 305. When the defibrillator circuit 305 is woken up, the management component 303 transmits the processed data information to the defibrillator circuit 305, and the defibrillator circuit 305 decides on its subsequent operation based on the data information.

[0047] The transmitting / receiving device can be a near-field communication (NFC) transmitter, with transmitter 101 being an NFC transmitter and receiver 102 being an NFC receiver.

[0048] Example 1

[0049] like Figure 2 As shown, an NFC transmitter is installed inside a device 103 that houses the defibrillator. Specifically, device 103 is a chassis, and the NFC receiver is the defibrillator itself.

[0050] The generating component 301 transmits electromagnetic waves to the receiving component 302 via the first antenna; the receiving component 302 receives the electromagnetic waves via the second antenna.

[0051] When the user does not need to remotely wake the defibrillator, the electromagnetic waves received by the NFC receiver contain energy. The receiving component 302 receives the energy and begins to operate. The electrical energy first supplies the defibrillator circuit 305 and indicates the device status information of the defibrillator in standby mode. The remaining electrical energy is managed by the management component 303 and stored in the energy storage component 304. When the defibrillator circuit 305 requires more energy, the management component 303 draws energy from the energy storage component 304 to supply the defibrillator circuit 305.

[0052] Example 2

[0053] like Figure 3 As shown, when a user wishes to perform a remote wake-up operation, the electromagnetic waves received by the NFC receiver also include data information. The data encoding and decoding integrated component in the receiving component 302 decodes the data information, and the management component decides to wake up the defibrillator circuit 305 based on the received data information.

[0054] When the defibrillator circuit 305 is activated, the management component 303 transmits the processed data information to the defibrillator circuit 305, and the defibrillator circuit 305 performs the next operation based on the data information, such as device self-test.

[0055] The defibrillator can send data to an NFC transmitter. Figure 201 shows the data transmission direction. The NFC transmitter remotely sends the information to the user via a network. The network can be 4G, 5G, Wi-Fi, wired, or other methods.

[0056] In this configuration, the NFC receiver acts as the data sender, and the NFC transmitter acts as the data receiver. The transmitter can be designed to have both a transmitting and receiving component, or a single component can have both transmitting and receiving functions.

[0057] The power received by NFC powers the defibrillator circuitry for daily standby indication of the device's status, self-testing, and network connectivity. In standby mode, the defibrillator is only indicated by a flashing green / red status indicator light. The self-test cycle can be configured for daily, weekly, or monthly self-tests; therefore, it consumes 0.48 mAh-0.6 mAh per day in standby mode.

[0058] NFC devices use a single antenna to combine communication and charging functions, achieving a charging speed of 1W. Calculating 1W charging at 12V, the current is 0.08A. A day's charging would be 0.08A * 24h = 1.92Ah. Therefore, NFC charging can provide a significant amount of energy. Part of this energy can be used in standby mode, and another part can be used in the wake-up state.

[0059] This invention utilizes the energy normally transmitted by NFC to cope with the energy consumption of the defibrillator's periodic self-test. The extra energy of NFC can be used for status display during standby, or the energy can be stored for use by the defibrillator, such as for short-term defibrillator self-test programs, thereby reducing the defibrillator's battery consumption.

[0060] This invention transmits data to the defibrillator via NFC, thereby enabling data communication with the chassis. This allows the defibrillator to be woken up at any time without consuming the defibrillator's battery power, and to perform self-tests, network connections, and other actions.

[0061] The applicant of this invention has provided a detailed description of the embodiments of the invention in conjunction with the accompanying drawings. However, those skilled in the art should understand that the above embodiments are merely preferred embodiments of the invention. The detailed description is only intended to help readers better understand the spirit of the invention and is not intended to limit the scope of protection of the invention. On the contrary, any improvements or modifications made based on the inventive spirit of the invention should fall within the scope of protection of the invention.
