Description

Technical Field

[0001] This application relates to the field of medical device technology, and more particularly to an active implantable medical device. Background Technology

[0002] Active implantable medical devices are medical instruments that are implanted in the human body for extended periods, including pacemakers, various nerve stimulators, and muscle stimulators. These devices deliver pulsed stimulation signals to the target treatment site via implanted electrodes to achieve therapeutic effects.

[0003] Active implantable medical devices generally consist of an in-body device and an external device. The in-body device is placed inside the body to treat the target area, while the external device is placed outside the body to wirelessly transmit data and wirelessly charge the in-body device. Specifically, the in-body device and the external device communicate via a Bluetooth module. Currently, to extend the battery life of the in-body device, existing technologies reduce the power consumption of individual components within the in-body Bluetooth module, thereby minimizing battery drain.

[0004] However, existing active implantable medical devices cannot guarantee the stability and safety of implantable medical devices while reducing the power consumption of Bluetooth modules. Summary of the Invention

[0005] This application provides an active implantable medical device that can solve the problem in the prior art that reducing the power consumption of the Bluetooth module cannot guarantee the stability and safety of the implantable medical device.

[0006] An active implantable medical device, comprising an in-body device and an external device;

[0007] The in-body device includes a treatment module, an in-body Bluetooth module, and a control unit. The treatment module is electrically connected to the control unit. The treatment module has a periodic working sequence. The control unit controls the treatment module to treat the human body. The in-body Bluetooth module is electrically connected to the control unit for information transmission.

[0008] The external device includes an external Bluetooth module, which selectively communicates with the internal Bluetooth module to transmit information from the external device to the internal device.

[0009] When any of the working sequences of the treatment module finishes execution, the in-body Bluetooth module and the external Bluetooth module establish a communication connection, and the control unit receives an information transmission request from the in-body Bluetooth module, the control unit and the in-body Bluetooth module begin data transmission, and the control unit receives Bluetooth data transmitted from the external Bluetooth module to the in-body Bluetooth module.

[0010] Optionally, the in-body Bluetooth module and the control unit are in a communication disconnected state under any of the following conditions:

[0011] No working sequence of the treatment module has been completed;

[0012] The in-body Bluetooth module and the external Bluetooth module are not connected in communication.

[0013] The control unit did not receive an information transmission request from the in-body Bluetooth module.

[0014] Optionally, when any working sequence of the treatment module finishes execution and the in-body Bluetooth module communicates with the external Bluetooth module, the control unit begins to determine whether the information transmission request has been received.

[0015] Optionally, when any working sequence of the treatment module ends and the in-body Bluetooth module and the external Bluetooth module are not connected, the control unit controls the treatment module to start executing the treatment task of the next working sequence.

[0016] Optionally, when the control unit receives the information transmission request, the control unit starts communicating with the in-body Bluetooth module and receives the Bluetooth data stored in the in-body Bluetooth module.

[0017] Optionally, when the control unit does not receive the information transmission request, the control unit controls the treatment module to start executing the treatment task of the next working sequence.

[0018] Optionally, the in-body device further includes an in-body wireless charging module and a battery. The control unit is electrically connected to the wireless charging module, and the wireless charging module is electrically connected to the battery, so that the control unit controls the wireless charging module to charge the battery. The control unit is also electrically connected to the battery so that the control unit can obtain the battery status.

[0019] When the control unit detects that the Bluetooth data contains a charging command, the control unit controls the in-body wireless charging module to charge the battery. The control unit and the in-body Bluetooth module continue to transmit data so that the control unit continuously feeds back the status of the battery to the in-body Bluetooth module.

[0020] Optionally, when the control unit does not detect a charging command in the Bluetooth data, the control unit disconnects data transmission from the in-body Bluetooth module to reduce power consumption, and the control unit controls the treatment module to start executing the treatment task of the next working sequence.

[0021] Optionally, after the control unit receives data indicating the end of charging transmitted by the in-body Bluetooth module, the control unit controls the wireless charging module to stop charging the battery. At the same time, the control unit disconnects data transmission from the in-body Bluetooth module to reduce power loss to the battery. The control unit then controls the treatment module to begin executing the treatment task of the next working sequence.

[0022] This application provides an active implantable medical device, comprising an in-body device and an external device. The in-body device includes a treatment module, an in-body Bluetooth module, and a control unit, while the external device includes an external Bluetooth module. Data transmission between the control unit and the in-body Bluetooth module occurs only when any of the treatment module's operating sequences has ended, the in-body Bluetooth module and control unit are in communication connection, and the control unit receives a data transmission request from the in-body Bluetooth module. When all three conditions are not met, the control unit disconnects from the in-body Bluetooth module to reduce power consumption. This active implantable medical device enables communication between the in-body Bluetooth module and the control unit after the treatment module's normal operating sequence has ended, and promptly closes their communication serial port when communication is not in progress. This reduces power consumption of the in-body Bluetooth module due to communication and avoids the impact of communication on the treatment module's operating sequence, ensuring the stability and safety of the active implantable medical device.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0031] To extend the battery life of the battery 110 in the in vivo device 100 of an active implantable medical device, existing technologies reduce the power consumption of the entire in vivo Bluetooth module 160 by lowering the power consumption of individual components within the module, thereby minimizing battery consumption. However, existing methods for reducing the power consumption of the in vivo Bluetooth module 160 do not consider the power consumption during connection and communication. Furthermore, communication by the in vivo Bluetooth module 160 can affect the timing of the treatment module 130 within the in vivo device 100, compromising the stability and safety of the medical device.

[0032] This application provides an active implantable medical device that, by changing the working mode of the in-vivo Bluetooth module 160 and coordinating the working sequence of the in-vivo Bluetooth module 160 and the treatment module 130, can both reduce the consumption of the in-vivo Bluetooth module 160 and improve the stability and safety of the active implantable medical device.

[0033] Figure 1 This is a schematic diagram illustrating the in-vivo device 100 and the external device 200 of an active input medical device according to an embodiment of this application. Figure 2 This is a schematic diagram illustrating the communication method between the in-vivo device 100 and the external device 200 of an active input medical device according to an embodiment of this application. Figure 3 This is a flowchart illustrating the operation of an active input medical device according to an embodiment of this application.

[0034] refer to Figure 1 As shown, an active implantable medical device includes an in-body device 100 and an external device 200.

[0035] The in-body device 100 includes a treatment module 130, an in-body Bluetooth module 160, and a control unit 140. The treatment module 130 is electrically connected to the control unit 140. The treatment module 130 processes the electrophysiological signals of the implanted individual and transmits them to the control unit 140. The control unit 140 then controls the treatment module 130 to stimulate and treat designated areas. Specifically, the treatment module 130 has a periodic operating sequence, and within each operating sequence, the treatment module 130 treats the affected body area. The in-body Bluetooth module 160 is electrically connected to the control unit 140, and the two exchange and transmit information. Specifically, the in-body Bluetooth module 160 transmits received data to the control unit 140 for processing; or the control unit 140 transmits its data to be transmitted to the in-body Bluetooth module 160, which then transmits this data to the external device 200.

[0036] The external device 200 includes an external Bluetooth module 240, which can pair and connect with the internal Bluetooth module 160 in the internal device 200 for data transmission. In other words, data transmission between the internal device 100 and the external device 200 is accomplished wirelessly between the internal Bluetooth module 160 and the external Bluetooth module 240. It is understood that the internal Bluetooth module 160 and the external Bluetooth module 240 can connect or disconnect. When disconnected, the control unit 140 controls the internal Bluetooth module 160 to turn off, reducing its power consumption. When information transmission is required, they connect, and information is transmitted from the internal Bluetooth module 160 to the external Bluetooth module 240, or vice versa.

[0037] refer to Figure 2 As shown, the control unit 140 of the in-body device 100 is connected to the in-body Bluetooth module 160 via a communication serial port, thereby transmitting information from the in-body Bluetooth module 160 to the control unit 140. The external Bluetooth module 240 in the external device 200 is connected to the in-body Bluetooth module 160 in the in-body device 100 via a wireless data port. Specifically, the transmitting port (TX) of the external Bluetooth module 240 sends Bluetooth information to the receiving port (RX) of the in-body Bluetooth module 160, or the transmitting port (TX) of the in-body Bluetooth module 160 sends information to the receiving port (RX) of the external Bluetooth module 240, realizing information interaction and transmission between the in-body Bluetooth module 160 and the external Bluetooth module 240.

[0038] Furthermore, within the internal Bluetooth module 160, the receiver (RX) is electrically connected to its communication serial port to transmit data received by the receiver (RX) to the control unit 140 via the serial port. The transmitter (TX) is also electrically connected to the serial port, allowing the control unit 140 to transmit data obtained by itself to the internal Bluetooth module 160 via the serial port, and then transmit this data to the external Bluetooth module 240 via the transmitter (TX). Essentially, the basic function of the internal Bluetooth module 160 is data transparent transmission, enabling transparent data transmission between the serial port and the wireless data port.

[0039] refer to Figure 3 As shown, in order to reduce the power consumption of the in-body Bluetooth module 160 and avoid the communication of the in-body Bluetooth module 160 affecting the working sequence of the treatment module 130, the control unit 140 will only open the communication serial port connected to the in-body Bluetooth module 160 to perform data transmission when any working sequence of the treatment module 130 is completed, the in-body Bluetooth module 160 is connected to the external Bluetooth module 240, and the control unit 140 receives the information transmission request sent by the in-body Bluetooth module 160.

[0040] If any working sequence of the treatment module 130 has not finished executing, or the internal Bluetooth module 160 and the external Bluetooth module 240 have not communicated, or the control unit 140 has not received an information transmission request from the internal Bluetooth module 160, then the internal Bluetooth module 160 and the control unit 140 are in a communication disconnected state, that is, the control unit 140 closes its communication serial port with the internal Bluetooth module 160 to reduce power consumption.

[0041] Continue to refer to Figure 3 As shown, when the control unit 140 detects that any working sequence of the treatment module 130 has ended, the control unit 140 begins to determine the connection status between the internal Bluetooth module 160 and the external Bluetooth module 240. When the control unit 140 detects that the internal Bluetooth module 160 and the external Bluetooth module 240 have established a communication connection, the control unit 140 begins to determine whether it has received an information transmission request. When the control unit 140 does not detect a communication connection between the internal Bluetooth module 160 and the external Bluetooth module 240, the control unit 140 controls the treatment module 130 to enter the next working sequence and continue to treat the target area.

[0042] Continue to refer to Figure 3As shown, when the control unit 140 detects that it has received an information transmission request from the in-body Bluetooth module 160, the control unit 140 opens the communication serial port with the in-body Bluetooth module and begins communication to receive Bluetooth data sent by the external Bluetooth module 240 to the in-body Bluetooth module 160; if the control unit 140 does not detect that it has received an information transmission request from the in-body Bluetooth module 160, the control unit 140 controls the treatment module 130 to start the next working sequence and continue to treat the target area.

[0043] Figure 4 This is a schematic diagram illustrating the connection between the control unit 140 and the in-vivo Bluetooth module 160 of an active input medical device according to an embodiment of this application. (Reference) Figure 4 As shown, the serial port transmitting port of the control unit 140 is connected to the serial port receiving port pin (BLE_RXD) of the internal Bluetooth module 160 to send data from the control unit 140 to the internal Bluetooth module 160; the serial port receiving port of the control unit 140 is connected to the serial port transmitting port pin (BLE_TXD) of the internal Bluetooth module 160 to send data from the internal Bluetooth module 160 to the control unit 140 via the communication serial port. The output pin MCU_DATA of the control unit 160 is connected to the internal Bluetooth module 160 to inform the internal Bluetooth module 160 whether the control unit 140 can receive data from the external Bluetooth module 240. Specifically, when the output pin MCU_DATA is high, it means that the control unit 140 can receive data from the internal Bluetooth module 160, and the control unit 140 opens the communication serial port connected to the internal Bluetooth module 160; when the output pin MCU_DATA is low, it means that the control unit 140 cannot receive data from the internal Bluetooth module 160 temporarily, and the internal Bluetooth module 160 closes the communication serial port connected to the control unit 140 to reduce power consumption.

[0044] The control pin (BLE_LINK) of the internal Bluetooth module 160 is electrically connected to the control unit 140 to indicate the connection status between the internal Bluetooth module 160 and the external Bluetooth module 240. When the internal Bluetooth module 160 and the external Bluetooth module 240 are connected, the control pin (BLE_LINK) of the internal Bluetooth module 160 outputs a high level to the control unit 140, and vice versa.

[0045] Specifically, after the in-body Bluetooth module 160 connects with the external Bluetooth module 240, in order to reduce the impact of Bluetooth communication on the working timing of the implantable medical device, the in-body Bluetooth module 160 places the received data in the buffer area. The in-body Bluetooth module 160 detects the status of the output pin MCU_DATA. If it is low, it means that the control unit 140 cannot receive data at this time. The in-body Bluetooth module 160 sends a one-byte pre-data, i.e., an information transmission request, to the control unit 140 to inform the control unit 140 that the in-body Bluetooth module 160 has received the data sent from the external Bluetooth module 240 and is waiting to transmit it to the control unit 140.

[0046] After the treatment module 130 finishes its working sequence, the control unit 140 checks the connection status of the internal Bluetooth module 160, specifically the status of the BLE_LINK pin. If the BLE_LINK pin is detected to be high, the control unit 140 checks whether pre_data has been received. If pre_data is received, the control unit 140 controls the output pin MCU_DATA to output a high level, informing the internal Bluetooth module 160 that the control unit 140 can now receive data. After the internal Bluetooth module 160 connects to the external Bluetooth module 240, and the internal Bluetooth module 160 detects that the output pin MCU_DATA is high, the internal Bluetooth module 160 immediately transmits the data to the control unit 140. After receiving and parsing the data, the control unit 140 controls the treatment module 130 to treat the target area.

[0047] Continue to refer to Figure 1 As shown, an in-vivo device 100 of an active implantable medical device also includes an in-vivo wireless charging module 150 and a battery 110. The battery 110 powers various components of the in-vivo device 100. Specifically, the battery 110 is electrically connected to an in-vivo power management module 120, which powers the components of the in-vivo device 100. A control unit 140 is electrically connected to the in-vivo wireless charging module 150, which in turn is electrically connected to the battery 110. When the control unit 140 receives a command to charge the battery 110, it controls the in-vivo wireless charging module 150 to charge the battery 110. Additionally, the battery 110 is also electrically connected to the control unit 140, allowing the control unit 140 to acquire the status of the battery 110 and transmit this status to an external Bluetooth module 240 via an in-vivo Bluetooth module 160, so that users are aware of the status of the battery 110 within the in-vivo device 100.

[0048] Continue to refer to Figure 3As shown, when the control unit 140 communicates with the internal Bluetooth module 160, after the control unit 140 determines that the received Bluetooth data contains a charging command, the control unit 140 controls the internal wireless charging module 150 to charge the battery 110. During the charging process, the control unit 140 and the internal Bluetooth module 160 continuously interact with each other, so that the control unit 140 can provide real-time feedback on the status of the battery 110 to the internal Bluetooth module 160 and receive data sent by the internal Bluetooth module 160 in real time. It can be understood that the internal Bluetooth module 160 sends the received data to the external Bluetooth module 240 in real time, and the external Bluetooth module 240 displays the data on the human-machine interface panel 220 of the external device 200, so that people are aware of the status of the battery 110, ensuring the safety of the medical device and avoiding harm to the human body. Specifically, the status of the battery 110 refers to battery status indicators such as temperature and charge level.

[0049] If the control unit 140 does not detect a charging command in the Bluetooth data, the control unit 140 disconnects the communication serial port connection with the in-body Bluetooth module 160 to reduce power consumption, and at the same time controls the treatment module 130 to start the next working sequence to continue treating the target area.

[0050] While the control unit 140 is controlling the in-body wireless charging module 150 to charge the battery 110, the control unit 140 communicates with the in-body Bluetooth module 160 in real time to exchange information. When the control unit 140 receives and parses the command data to end charging transmitted by the in-body Bluetooth module 160, the control unit 140 controls the wireless charging module 150 to end charging the battery 110, and at the same time closes the communication serial port with the in-body Bluetooth module 160 to disconnect data transmission in order to reduce power consumption. The control unit 140 then controls the treatment module 130 to start the next working sequence and continue to treat the target area.

[0051] It is understandable that when the in-body Bluetooth module 160 is connected to the external Bluetooth module 240, and the control unit 140 controls the in-body wireless charging module 150 to charge the battery 110, in order to ensure the stability and safety of the active implantable medical device, the control unit 140 needs to frequently and periodically read the status of the battery 110 (including status information such as temperature, current and voltage), and adjust the charging parameters (such as frequency, duty cycle, etc.) of the external wireless charging module 250 of the external device 200 in real time to ensure charging safety. It is also understandable that the external wireless charging module 250 is paired with the in-body wireless charging module 150 so that the in-body wireless charging module 150 can charge the battery 110.

[0052] Specifically, after the treatment module 130 finishes executing its working sequence, the internal Bluetooth module 160 connects with the external Bluetooth module 240, and the control device 140 receives a charging command from the Bluetooth data transmitted by the internal Bluetooth module 160, the external device 200 needs to obtain the status of the battery 110 in the internal device 100. The control unit 140 pauses the treatment work of the treatment module 130, that is, the treatment module 130 does not start executing its working sequence. The control unit 140 controls the output pin MCU_DATA to continuously output a high level. The internal Bluetooth module 160 directly transmits the data received from the external Bluetooth module 240 to the control unit 140; or the control unit 140 transmits the obtained battery 110 status information to the internal Bluetooth module 160, and then the internal Bluetooth module 160 sends it to the external Bluetooth module 240. Until the control unit 140 receives a command to end charging or the internal Bluetooth module 160 disconnects from the external Bluetooth module 240, the control unit 140 controls the internal wireless charging module 150 to end charging the battery 110, and the treatment module 130 begins the next working sequence to continue treating the target area.

[0053] Specifically, the control overview of the in-body Bluetooth module 160 in this application embodiment is as follows:

[0054] 1. When the internal Bluetooth module 160 does not need to broadcast, the control unit 140 puts the internal Bluetooth module 160 into a sleep state, stops the clock of the internal Bluetooth module 160, that is, stops running tasks and waits to be woken up;

[0055] 2. When the internal Bluetooth module 160 is not connected to the external Bluetooth module 240, the control unit 140 controls the internal Bluetooth module 160 to open and close the communication serial port. The internal Bluetooth module 160 opens the communication serial port only when the control unit 140 needs to transmit data with the internal Bluetooth module 160. After the transmission is completed, the communication serial port is closed to reduce the power consumption of the internal Bluetooth module 160 due to communication.

[0056] 3. When the internal Bluetooth module 160 is connected to the external Bluetooth module 240 but the internal wireless charging module 150 is not charging the battery 110, to reduce the impact of Bluetooth communication on the operating timing of the treatment module 130, after receiving data from the external Bluetooth module 240, the internal Bluetooth module 160 first sends a pre-arranged data to the control unit 140, informing the control unit 140 that it has received data and is waiting to transmit it to the control unit 140. Once the control unit 140 can receive data from the internal Bluetooth module 160, the control unit 140 opens the communication serial port with the internal Bluetooth module 160, and the internal Bluetooth module 160 transmits the data transparently to the control unit 140.

[0057] 4. When the in-body Bluetooth module 160 is connected to the external Bluetooth module 240 and the battery 110 of the in-body wireless charging module 150 is charging, in order to ensure the stability and safety of the implanted active implantable medical device, the control unit 140 needs to frequently and periodically read the status of the battery 110 (including status information such as temperature, current and voltage), and adjust the charging parameters (such as frequency, duty cycle, etc.) of the external wireless charging module 250 of the external device 200 in real time to ensure charging safety. At this time, the in-body Bluetooth module 160 directly transmits the data received from the external Bluetooth module 240 to the control unit 140; or the control unit 140 transmits the obtained battery 110 status information to the in-body Bluetooth module 160, and then the in-body Bluetooth module 160 sends it to the external Bluetooth module 240. The external Bluetooth module 240 displays the data on the human-machine interface panel 220 of the external device 200 so that people know the status of the battery 110, ensuring the safety of the medical device and avoiding harm to the human body.

[0058] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
