Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a register access system and control method for an in vivo stimulation device. Background Technology

[0002] In medical electrical stimulation applications, the external control device plays a crucial role in continuously adjusting the stimulation parameters of the internal stimulation device. However, directly modifying the stimulation parameters of the internal device via the external control device during stimulation could potentially cause charge imbalance, leading to nerve damage in the patient. Therefore, stimulation is generally paused before parameter adjustments are made. However, it's important to note that prolonged pauses not only reduce the patient's experience but also negatively impact the evaluation of the parameter adjustment's effectiveness.

[0003] Currently, users mainly use specific interfaces to perform read and write operations on the registers inside the internal stimulation device, thereby enabling the internal stimulation device to operate according to specific parameters. Figure 1 This is a schematic diagram illustrating the register access system of a typical in vivo stimulation device. Figure 1 As shown, the wireless communication module is responsible for accessing the general-purpose registers. Simultaneously, this module can also communicate wirelessly with the external control device, allowing the external control device to conveniently read and write to the registers. However, during the application of stimulation signals to the patient, if the user needs to modify parameters, it is usually necessary to pause the current operation, reconfigure the registers, and then resume operation with the new parameters.

[0004] Among the existing methods, there is another method that utilizes a shadow register. This method can configure user-set parameters into a preload register without interrupting the current operation, and then load them into the shadow register at an appropriate time, thereby ensuring the continuous operation of the stimulus signal. Figure 2 This diagram illustrates a register access system for an in vivo stimulation device with added preload register and shadow register modules. During the application of stimulation signals to the patient, the external control device accesses the preload register of the in vivo stimulation device wirelessly. Only after the stimulation signal generation module completes a full stimulation cycle and reaches charge balance is the content stored in the preload register module loaded into the shadow register module, thereby updating the stimulation parameters during stimulation. However, when using the shadow register scheme, the numerous and complex stimulation parameters often lead to excessive resource consumption and a significant increase in power consumption, ultimately negatively impacting the electrical stimulation effect.

[0005] Therefore, there is an urgent need to improve the register access system and control method of in vivo stimulation devices.

[0006] The above description of the background technology is only for the purpose of facilitating a deeper understanding of the technical solution of the present invention (the technical means used, the technical problems solved, and the technical effects produced, etc.), and should not be regarded as an admission or in any form an implication that the information constitutes prior art known to those skilled in the art.

The wireless communication module is further configured to, during the operation of the stimulation signal generation module, when it receives modified parameter information from an external control device, transmit the received modified parameter information to the preload register module and send a parameter information modification instruction to the stimulation signal generation module. The stimulation signal generation module is configured to, when it receives a parameter information modification instruction, generate an updated remapping pattern and send the updated remapping pattern to the preload register module. The preload register module is configured to map the modified parameter information to the corresponding registers of the shadow register module according to the updated remapping pattern. The stimulation signal generation module is configured to, after the current stimulation cycle ends and before entering the next stimulation cycle, generate a new stimulation signal based on the modified parameter information in the corresponding registers of the shadow register module.

[0012] Preferably, the wireless communication module is a radio frequency identification (RFID) communication module.

[0013] According to an embodiment of the present invention, a control method for a register access system of an in vivo stimulation device is provided, comprising: receiving parameter information from an external control device by a wireless communication module and transmitting the received parameter information to a preloaded register module; transmitting parameter information to a shadow register module by the preloaded register module according to a preset remapping mode; and obtaining parameter information from the shadow register by a stimulation signal generation module and generating a stimulation signal based on the obtained parameter information.

[0014] The control method of the register access system of the in vivo stimulation device according to an embodiment of the present invention further includes: setting a preset remapping mode by the stimulation signal generation module according to a preset stimulation mode, and writing the preset remapping mode to the preload register module.

[0015] The control method of the register access system of the in vivo stimulation device according to an embodiment of the present invention further includes: the preload register module transmitting data in the corresponding register of the preload register module to the corresponding register of the shadow register module according to a preset remapping mode; wherein the preload register module and the shadow register module each include multiple registers, and the storage capacity of the preload register module is smaller than the storage capacity of the shadow register module.

[0017] Preferably, the wireless communication module is a radio frequency identification (RFID) communication module.

[0018] The present invention adopts the above technical solution, which has the following beneficial effects:

[0019] 1. Achieve non-pause-free configuration and operation:

[0020] This invention utilizes a shadow register mechanism, allowing users to configure the registers of the in vivo stimulation device without pausing the current operation. This ensures that the in vivo stimulation device can continuously and stably output stimulation throughout its operation, effectively avoiding stimulation interruptions caused by register configuration changes. For medical applications with extremely high requirements for stimulation continuity, this uninterrupted stimulation output is crucial, significantly reducing adverse clinical reactions caused by stimulation interruptions. Simultaneously, this function empowers doctors and users to adjust stimulation parameters in real time according to actual treatment needs, greatly enhancing the adaptability of the in vivo stimulation device to different treatment scenarios and individual differences, significantly improving treatment efficacy and the device's practicality.

[0021] 2. Streamlined hardware architecture and resource optimization:

[0022] By utilizing a remapping technique from preloaded registers to shadow registers, the total number of registers within the in vivo stimulation device is reduced. This optimization not only simplifies hardware design complexity, effectively reduces chip area, and lowers manufacturing costs, but also significantly reduces system resource consumption, resulting in a more compact overall device structure and higher operating efficiency. This optimized allocation of hardware resources provides strong support for the miniaturization and integration of in vivo stimulation devices.

[0023] 3. Reduce system power consumption:

[0024] The reduction in the number of registers directly leads to a decrease in system power consumption, effectively improving energy efficiency, extending battery life, or reducing overall energy consumption. Furthermore, the reduction in frequent operations such as register switching and data transmission further lowers the power consumption of the in vivo stimulation device. This is significant for implantable or portable in vivo stimulation devices, as it reduces battery size and weight, improving portability and wearing comfort, while also mitigating potential risks caused by power consumption-related issues such as overheating, thereby significantly improving system stability and reliability.

[0025] 4. Enhance system performance:

[0026] By strategically utilizing shadow registers and preload registers, register access speed is accelerated, and data processing efficiency is improved. For in vivo stimulation devices requiring rapid response and precise control, this advantage ensures that stimulation signals are output in a timely and accurate manner, providing a solid guarantee for achieving more efficient and precise therapeutic effects and powerfully promoting technological advancements in the clinical application of in vivo stimulation devices.

[0027] In summary, the register access system and control method for the in vivo stimulation device provided by this invention achieve multiple beneficial effects, including pause-free configuration, reduced register count, lower system power consumption, enhanced configuration flexibility, and improved system performance, through the remapping technology of shadow registers and preloaded registers. These significant advantages provide strong technical support for the further development and widespread application of in vivo stimulation devices, and have extremely high clinical application value and market prospects.

[0028] The exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. For clarity, the same components in different drawings are shown with the same reference numerals. It should be noted that the drawings are for illustrative purposes only and are not necessarily drawn to scale. In these drawings:

[0030] Figure 2 This is a schematic diagram illustrating the register access system of an in vivo stimulation device with added preload register and shadow register modules.

[0031] Figure 3 This is a schematic diagram illustrating the register access system of an in vivo stimulation device according to an embodiment of the present invention. Detailed Implementation

[0032] The following provides a detailed description of the embodiments of the present invention. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0033] Figure 3 A schematic diagram illustrating the register access system of an in vivo stimulation device according to an embodiment of the present invention. See also Figure 3 The register access system of the in vivo stimulation device according to an embodiment of the present invention may include: a wireless communication module 101, a preloaded register module 102, a shadow register module 103, and a stimulation signal generation module 104.

[0034] The wireless communication module 101 can be electrically connected to the preload register module 102, and can access and configure the preload register module 102. Furthermore, the wireless communication module 101 can also wirelessly communicate with an external control device (not shown), thereby enabling functions such as configuring various parameters, monitoring the status, and exchanging data between the external and internal stimulation devices. The wireless communication module 101 can be configured to receive parameter information from the external control device and transmit the received parameter information to the preload register module 102.

[0035] Through the wireless communication module, users can send various parameter information, such as stimulation intensity, frequency, mode, pulse width, and delay time, to the preloaded register module 102 using an external control device. This allows for precise adjustment of the working parameters of the internal stimulation device according to the patient's physical condition and treatment needs, thus achieving personalized treatment plans.

[0036] In addition, the wireless communication module can periodically read the working status information of the in vivo stimulation device from the preload register and send it to the external control device. This working status information includes key indicators such as battery power, whether the circuit is working properly, the working status of the stimulation electrode, and temperature. Medical staff can use this real-time data to promptly identify potential problems and ensure the safety and stability of the treatment process.

[0037] The wireless communication module 101 can flexibly select the most suitable wireless communication technology, such as RFID, Wi-Fi, Zigbee, etc., according to specific application requirements and scenario characteristics, as long as it can communicate wirelessly with the external wireless communication device. According to an embodiment of the present invention, the wireless communication module 101 can be a Radio Frequency Identification (RFID) communication module, etc. The RFID communication module transmits signals via radio waves, eliminating the need for direct contact with the external control device, thus avoiding the infection risks, mechanical damage, and limitations on patient movement that may arise from wire connections, improving patient comfort and quality of life. The RFID communication module is small in size, suitable for integration into miniaturized internal stimulation devices, and has low power consumption, which does not significantly impact the device's battery life, extending the lifespan of the internal stimulation device.

[0038] The preload register module 102 can be electrically connected to the shadow register module 103, serving as a buffer for the shadow register module 103. Data in the preload register module 102 can be transferred to the shadow register module 103.

[0039] The shadow register module 103 can be electrically connected to the stimulus signal generation module 104, so that the stimulus signal generation module 104 can read the data in the shadow register module and generate a stimulus signal according to the various parameters stored in the shadow register module 103.

[0040] According to an embodiment of the present invention, among all the registers involved in the stimulus signal generation module 104, the shadow register module 103 has the largest storage capacity, and the storage capacity of the preload register module 102 is smaller than that of the shadow register module 103. The preload register module 102 and the shadow register module 103 may each include multiple registers, and the number of registers they contain differs, thereby forming different register regions.

[0041] Data transfer between the preload register module 102 and the shadow register module 103 is performed via remapping. The preload register module 102 serves as the source register to be remapped, and the shadow register module 103 serves as the target register. The preload register module 102 can be mapped to the corresponding register in the shadow register module 103 according to a preset remapping pattern. This allows data in the corresponding register of the preload register module 102 to be transferred to the corresponding register in the shadow register module 103, reducing the total number of registers within the in vivo stimulation device, reducing resource usage, and lowering the power consumption of the in vivo stimulation device.

[0042] The stimulation signal generation module 104 can be electrically connected to the preload register module 102. The stimulation signal generation module 104 can write control values ​​to the preload register module 102 to set parameters such as the mapping method between the preload register module 102 and the shadow register module. The stimulation signal generation module 104 can set specific mapping modes (mapping relationship tables) according to different stimulation requirements to achieve different stimulation modes. In practical applications, different stimulation modes may correspond to different treatment needs, experimental conditions, or equipment operating states.

[0043] During a single stimulus, the stimulus signal generation module 104 does not need to use all registers of the shadow register module 103. The stimulus signal generation module 104 can select the corresponding register in the shadow register module 103 to be mapped to based on a preset stimulus mode (i.e., its corresponding preset remapping mode). Accordingly, the stimulus signal generation module 104 stores a mapping table between the preloaded register module 102 and the shadow register module 103 corresponding to different stimulus modes.

[0044] In practical applications, the same address in the preload register module 102 may be mapped to different locations in the shadow register module 103. For example, in stimulus mode 1, to meet the specific data processing and storage requirements of this mode, the first ten registers of the preload register module 102 are mapped to the first group of registers in the shadow register module 103. This mapping relationship allows the system to quickly and accurately call and process relevant data during the operation of stimulus mode 1. When switching to stimulus mode 2, since stimulus mode 2 has different operating logic and data processing requirements than stimulus mode 1, the first ten registers of the preload register module 102 can be mapped to the second group of registers in the shadow register module 103. These two different mapping relationships demonstrate the adaptability and flexibility of the system for different stimulus modes. However, it should be noted that the mapping relationships listed here are merely examples, and the present invention is not limited to the grouping, division, and mapping methods of registers in the preload register module 102 and the shadow register module 103.

[0045] In fact, based on the implementation scheme of this invention, a variety of mapping strategies can be derived to adapt to more complex and varied application scenarios. This flexible mapping mechanism has significant advantages; it can dynamically adjust the mapping relationship between registers according to different stimulus patterns, thereby effectively reducing the number of registers in the preloaded register module, avoiding unnecessary waste of hardware resources, and improving system performance while reducing hardware costs.

[0046] Furthermore, different stimulus modes may use the same shadow registers in shadow register module 103, all of which are mapped from fixed locations in preload register module 102. For example, in stimulus mode 1, the first ten registers of preload register module 102 can be mapped to the first set of registers in shadow register module 103. When switching to stimulus mode 2, the first ten registers (or the next ten registers) of preload register module 102 can be mapped to the first set of registers in shadow register module 103. This method of mapping the same shadow registers from fixed locations in preload register module 102 ensures efficient access to critical data under different stimulus modes while avoiding resource waste caused by repeatedly setting registers, further demonstrating the rationality and efficiency of the system design.

[0047] The technical solution provided by this invention offers a wide range of possibilities for the design of diverse register mapping relationships. Researchers can flexibly design the most suitable mapping scheme according to different application scenarios and actual needs, further expanding the application scope and therapeutic effect of in vivo stimulation devices.

[0048] It is worth noting that the mapping relationship between the registers of the preload register module 102 and the shadow register module 103 is fixed after the settings are completed and cannot be changed arbitrarily. This fixedness plays a crucial role in ensuring the stability and reliability of the system operation. Before tape-out (i.e., mass production of chips), functional simulation is used to ensure the accuracy of the mapping relationship between the registers of the preload register module 102 and the shadow register module 103.

[0049] In the early stages of chip manufacturing, specialized simulation tools are used to simulate the chip's functional operation and comprehensively verify the mapping relationship. Only when the verification results show that the mapping relationship is completely correct will it be finalized. This process effectively ensures the stability and repeatability of the device in actual operation, avoiding system failures or abnormal behaviors caused by incorrect mapping relationships.

[0050] Furthermore, the integrity and reliability of the mapped data are guaranteed by the digital circuit logic. Throughout the entire data transmission and processing process, the digital circuit performs rigorous verification and error correction operations on the data according to established logical rules. Whether it is the writing, reading, or transmission of data, the digital circuit ensures that the data flows and is used accurately according to the established mapping relationship, thus providing a solid data foundation for the stable operation of the system.

[0051] During the operation of the stimulus signal generation module 104, the wireless communication module 101 can modify the information stored in the preload register module 102. The preload register module 102 can map the modified parameters to the corresponding registers in the shadow register module 103, i.e., the corresponding registers in the shadow register module 103 undergo synchronous update operations. The wireless communication module 101 can also send a parameter information modification instruction to the stimulus signal generation module 104 at any time to notify the stimulus signal generation module 104 to modify the parameter information. After receiving the parameter information modification instruction, the stimulus signal generation module 104 generates a stimulus mode update instruction (which includes the remapping mode from the preload register module to the shadow register module) and sends the stimulus mode update instruction to the preload register module 102. Furthermore, the stimulus signal generation module 104 can obtain updated parameter information from the shadow register module 103 after the current stimulus cycle ends and before the next stimulus cycle begins, thereby generating a new stimulus signal.

[0052] The operation of the register access system of the in vivo stimulation device according to an embodiment of the present invention will now be described in detail. The operation of the register access system of the in vivo stimulation device according to an embodiment of the present invention includes the following steps:

[0053] 1. Steps for configuring remapping mode.

[0054] The stimulation signal generation module 104 sets the remapping relationship table from the preload register module 102 to the shadow register module 103 according to the preset stimulation mode.

[0055] Functional simulation is performed before tape-out. The remapping mode from the preloaded register module 102 to the shadow register module 103 is determined according to the preset stimulus mode to ensure that the mapping is correct and fixed. The digital circuit logic ensures the integrity and reliability of the mapped data.

[0056] 2. Stimulus execution steps.

[0057] The stimulus signal generation module 104 acquires data from the shadow register module 103. Based on the acquired data, it generates a stimulus signal according to the logic corresponding to the current stimulus mode.

[0058] 3. Parameter adjustment steps.

[0059] During the operation of the stimulation signal generation module 104, the external control device can modify the parameters of the preload register module 102 through the wireless communication module 101.

[0060] The wireless communication module 101 can receive modified parameter information from the external control device and can send parameter information modification instructions to the stimulation signal generation module 104 at any time. When the stimulation signal generation module 104 receives the parameter information modification instructions, it generates a stimulation mode update instruction (which includes an updated remapping mode) and sends the stimulation mode update instruction to the preload register module 102.

[0061] The preload register module 102 can map the modified parameter information to the corresponding registers of the shadow register module 103 according to the updated remapping mode.

[0062] After the current stimulation cycle ends and before entering the next stimulation cycle, the stimulation signal generation module 104 generates a new stimulation signal based on the modified parameter information in the corresponding register of the shadow register module 103.

[0063] Therefore, the register access system of the in vivo stimulation device according to an embodiment of the present invention allows parameters to be modified while the stimulation signal generation module is operating and updated after the current stimulation cycle ends. This design enables the system to adjust stimulation parameters in a timely manner according to actual conditions, adapting to different application scenarios, such as the dynamic adjustment needs in medical treatment. Furthermore, the register access system of the in vivo stimulation device according to an embodiment of the present invention utilizes the remapping of preloaded registers to shadow registers, reducing the total number of registers within the in vivo stimulation device. This not only simplifies hardware design, reduces chip area and cost, but also reduces resource usage, making the device more compact and efficient.

[0064] The various embodiments of the present invention are not an exhaustive list of all possible combinations, but are intended to describe representative aspects of the invention, and the contents described in the various embodiments can be applied independently or in two or more combinations.
