Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a charging device, a medical system and a charging control method of implantable medical equipment.
Background
Batteries are an indispensable and important component of many electronic products today, and they provide a source of energy for the entire electronic product. The battery life tends to limit the performance of the entire electronic product, especially for implantable medical devices. When the implanted batteries are exhausted, the patient is often forced to undergo surgery again to replace the entire set of equipment, not only at great expense, but also with the additional risks and psychological burdens associated with surgery.
With the gradual maturity of wireless charging technology, the application scenarios are also wider. Besides the aspects of mobile phones and electric automobiles which people contact daily, the implantable medical device also has a bright prospect in the field of implantable medical devices. The wireless charging technology has the inherent technical advantages in the aspect of implantable medical equipment, the energy transmitting part and the energy receiving part of the wireless charging technology are independent from each other and are not in contact with each other without exposing an additional lead, the sealing performance of the implantable medical equipment in vivo is enhanced, and the corrosion risk of parts of the equipment caused by long-term implantation in vivo and the local infection risk of a patient are reduced.
After the implantable medical equipment is combined with the wireless charging technology, the service life of the medical equipment can be greatly prolonged, a patient can be effectively implanted for the whole life at one time, the size of a battery in the implantable medical electronic equipment can be reduced, the implantable medical electronic equipment is more miniaturized, and the implanted operation is more minimally invasive.
The existing wireless charging technology mainly utilizes an electromagnetic field induction principle and adopts a coupling mode of a transmitting coil and a receiving coil to transfer energy. The energy transmission path is from the external charging device, the external charging coil, the implanted charging coil to the rechargeable battery of the implanted medical device.
In the actual use process of the whole wireless charging system, engineering designers have difficulty in controlling the coupling coefficient. The magnitude of the coupling coefficient depends on the relative positional relationship of the transmitting coil (outside the body) and the receiving coil (inside the body). When the transmitting coil and the receiving coil are coaxial and parallel and are close to each other, the coupling coefficient is high. The charging efficiency of the whole wireless charging system is directly influenced by the coupling coefficient. The two are in positive correlation, namely: under the same other conditions, the higher the coupling coefficient is, the higher the charging efficiency of the wireless charging is. Since the position of the receiving coil (in vivo) is not movable after the implantation operation, the position of the transmitting coil is important for the charging efficiency of the whole system.
In actual product use, due to the fact that the understanding of the wireless charging technical principle and the requirements of the patient and the family members thereof is different, it is difficult to ensure that the implantable medical device has the optimal charging efficiency in the wireless charging.
It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the invention and therefore may include information that does not constitute prior art that is already known to a person of ordinary skill in the art.

As shown in fig. 1, an embodiment of the present invention provides a charging apparatus for an implantable medical device, where the implantable medical device to be charged includes a receiving coil, and the charging apparatus M100 includes:
the wireless charging device comprises a wireless charging transmitting module M110 and a transmitting coil M120, wherein the wireless charging transmitting module is used for transmitting electric energy to the outside through the transmitting coil M120;
a first control module M130, configured to acquire a position state of the transmitting coil M120 relative to the receiving coil;
a position indication module M140, configured to send a position indication signal corresponding to the position status of the transmitting coil M120.
In the charging device of the present invention, the wireless charging transmitting module M110 transmits electric energy to the receiving coil of the implantable medical device through the transmitting coil M120, so as to charge the implantable medical device. The first control module M130 is further configured to obtain a position status of the transmitting coil M120 relative to the receiving coil, and send out a position indication signal corresponding to different position statuses through the position indication module M140. The user (such as the patient and family members thereof) can determine the relative position state of the current transmitting coil M120 and the current receiving coil according to the position indication signal, so that the patient and the family members thereof are quickly guided to correctly place the transmitting coil, and the method is simple, easy to understand, convenient to operate and suitable for all people. By correctly placing the transmitting coil, the charging efficiency can be significantly improved. The charging device may be applied to a variety of implantable medical devices, such as subcutaneous cardioverter-defibrillator (SICD), implantable cardioverter-defibrillator (ICD), implantable Pacemaker (PM), implantable cardiac resynchronization therapy device (CRT), and the like.
As shown in fig. 2, an embodiment of the present invention further provides a medical system, including:
a charging device M100 of the implantable medical device;
the implantable medical device M200 includes a medical function module M230, a wireless charging receiving module M210 and a receiving coil M220, wherein the wireless charging receiving module M210 obtains electric energy from the transmitting coil M120 through the receiving coil M220.
In the charging process, the wireless charging transmitting module M110 of the charging device M100 is responsible for controlling the output of energy and converting the electric energy into magnetic energy through the transmitting coil M120 to be transmitted. The receiving coil M220 of the corresponding implantable medical device M200 converts the received magnetic energy into electric energy to be transmitted to the wireless charging receiving module M210. The wireless charging receiving module M210 is provided with a storage battery for storing electric energy received by the wireless charging receiving module M210 and supplying power to each module.
For example, for an implantable cardioverter defibrillator, the medical function module M230 at least includes at least one of an electrocardiograph monitoring module, an electrocardiograph analysis module and a cardiac defibrillation module, the electrocardiograph monitoring module is configured to acquire an electrocardiograph signal, the electrocardiograph analysis module is configured to analyze the electrocardiograph signal and determine whether defibrillation is required, and the cardiac defibrillation module is configured to release electric energy to a defibrillation electrode when defibrillation is required. For the implantable pacemaker, the medical functional module M230 at least includes an electrocardiographic monitoring module and a cardiac pacing module, the electrocardiographic monitoring module is configured to acquire electrocardiographic signals, and the cardiac pacing module is configured to release electrical energy to the pacing electrode when pacing is needed.
In this embodiment, the first control module of the charging device obtains the position state of the transmitting coil relative to the receiving coil, and may adopt a plurality of ways:
(1) the first control module acquires parameters of a charging circuit, and determines the position state of the transmitting coil relative to the receiving coil according to the preset corresponding relation between the parameters of the charging circuit and the position state.
As shown in fig. 3, in this embodiment, the position states may be divided into a first state a in which the receiving coil is not detected, a second state in which the receiving coil is detected but the transmitting coil is not within the optimum charging position range, and a third state C in which the receiving coil is detected and the transmitting coil is within the optimum charging position range. In particular, the second state also includes a first sub-state B1 and a second sub-state B2. In fig. 3, the first circle outside the receiving coil is within the optimal charging position range, the second circle is the boundary between the first sub-state B1 and the second sub-state B2 of the second state, and the third circle is outside the receiving coil and corresponds to the first state a. Specifically, the first state a corresponds to the distance between the transmitting coil and the optimal charging position range being equal to or greater than n2, the first sub-state B1 of the second state corresponds to the distance between the transmitting coil and the optimal charging position range being greater than n1 and less than n2, the second sub-state B2 of the second state corresponds to the second sub-state between the transmitting coil and the optimal charging position range being greater than 0 and less than or equal to n1, n1< n2, the second sub-state B2 is the closer state, the first sub-state B1 is the farther state, and the third state C corresponds to the transmitting coil being within the optimal charging position range. The charging circuit parameters may include, but are not limited to, voltage, current, coupling coefficient, and the like. The closer the transmitting coil is to the receiving coil, the higher the voltage is, the higher the current is, and the larger the coupling coefficient is, and conversely, the farther the transmitting coil is from the receiving coil, the smaller the voltage is, the smaller the current is, and the smaller the coupling coefficient is. For example, when the voltage is used as the charging circuit parameter, the corresponding relationship between the charging circuit parameter and the position state may be set as follows: the first state corresponds to a voltage less than U1, the first sub-state of the second state corresponds to a voltage greater than or equal to U1 and less than U2, the second sub-state of the second state corresponds to a voltage greater than or equal to U2 and less than U3, the third state corresponds to a voltage greater than or equal to U3, and U1< U2< U3. For another example, when the current is used as the charging circuit parameter, the corresponding relationship between the charging circuit parameter and the position state may be set as follows: the current corresponding to the first state is less than I1, the first sub-state of the second state corresponds to the current being equal to or greater than I1 and less than I2, the second sub-state of the second state corresponds to the current being equal to or greater than I2 and less than I3, the third state corresponds to the current being equal to or greater than I3, and I1< I2< I3. In other alternative embodiments, the charging circuit parameter may also be other parameters (not limited to the several parameters listed here) such as voltage frequency, current frequency, temperature, etc., and by setting the range of the charging circuit parameter corresponding to different position states, the corresponding position state may be determined according to the charging circuit parameter value. And two or three different charging circuit parameters may be combined to determine the position state, for example, setting the parameters corresponding to the third state to have a voltage greater than XX and a current greater than XX, etc. In other embodiments, the division of the position states is not limited to the division in fig. 3, and for example, the division may be simply divided into two position states within the optimal charging position range and outside the optimal charging position range, or the second state is not divided into two sub-states, or the second state is further divided into more sub-states, and so on.
In the mode (1), the following two sub-modes can be specifically classified according to whether the charging circuit parameter is obtained from the transmitting coil of the charging device or the receiving coil of the implantable medical device:
(1.1) the first control module obtains charging circuit parameters, including the first control module obtaining charging circuit parameters of a transmitting coil of the charging device, such as obtaining parameters of voltage, current and the like of the transmitting coil.
(1.2) the implanted medical device obtaining the charging circuit parameters of the receiving coil. The first control module obtains charging circuit parameters, including the first control module communicating with the implantable medical device, and obtaining the charging circuit parameters of the receive coil from the implantable medical device.
In the mode (1.1), the charging device can determine the position state of the transmitting coil relative to the receiving coil only by acquiring the charging circuit parameters of the transmitting coil of the charging device and without communication with the implantable medical device, so that the position state can be directly indicated, and the working process is simpler. However, this approach may be misleading, for example, when the transmitting coil is close to other non-target coils, the position state corresponding to the second state or even the third state is also detected. Compared with the method, the method (1.2) has higher judgment accuracy, and the position state of the transmitting coil relative to the receiving coil can be accurately determined through the analysis of the charging circuit parameters of the receiving coil.
(2) The implantable medical device obtains the charging circuit parameters of the receiving coil, and determines the position state of the transmitting coil relative to the receiving coil according to the charging circuit parameters of the receiving coil. Specifically, the implantable medical device also determines the position status according to the preset corresponding relationship between the charging circuit parameter and the position status, for example, the corresponding relationship between the voltage range and the position status or the corresponding relationship between the current range and the position status is adopted.
The first control module of the charging device is in communication with the implantable medical device, and acquires the position state of the transmitting coil relative to the receiving coil from the implantable medical device, that is, the first control module acquires the judgment result of the position state from the implantable medical device, and can directly control the indicating mechanism to send out a corresponding indicating signal according to the received position state.
As shown in fig. 4, a block diagram of an implantable medical device in one specific example is shown. In this specific example, the charging device M100 further includes a first wireless communication module M150, the implantable medical device M200 further includes a second wireless communication module M250, and the first control module M130 performs data communication with the second wireless communication module M250 of the implantable medical device M200 through the first wireless communication module M150. The first wireless communication module M150 and the second wireless communication module M250 may be a bluetooth communication module, a WIFI communication module, a 3G/4G/5G communication module, or the like. The implantable medical device M200 further includes a second control module M240, configured to obtain a charging circuit parameter of the receiving coil M220, and send the charging circuit parameter of the receiving coil M220 to the charging device M100 through the second wireless communication module M250, or the second control module M240 is configured to obtain the charging circuit parameter of the receiving coil M220, determine a position state of the transmitting coil M120 relative to the receiving coil M220 according to the charging circuit parameter, and send the position state of the transmitting coil M120 to the charging device M100 through the second wireless communication module M250. In this instance, the charging device M100 may further include other functional modules, for example, a power module, which transmits the storage battery or the commercial power to the receiving coil M220 through the wireless charging transmitting module M110 and the transmitting coil M120, and the power module may supply power to the respective modules of the charging device M100.

receiving, from the implantable medical device, a positional state of a transmit coil relative to the receive coil.
In a specific example, the steps involved in the specific implementation of the charging control method are described in detail below with reference to fig. 3, 6, and 8.
S010: judging whether the insertion of the charging patch is detected;
if not, returning to the step S010 again after a preset interval time;
if the user (such as the patient or his family members) inserts the cable of the charging patch into the charging device host, the insertion of the charging patch can be detected, and the process continues to step S020: carrying out periodic self-check on the charging patch, and judging whether the charging patch passes the periodic self-check, wherein the periodic self-check can comprise detecting whether functions such as a transmitting coil, an indicating module and the like are normal;
if the periodic self-check is not passed, the step S030 is continued: entering an abnormal state, displaying an abnormal state indicating signal, for example, the annular LED indicator lamp 32 is normally on and displays red to indicate the user to replace the charging patch;
if the periodic self-test is passed, the step S110 is continued: acquiring a charging circuit parameter, and judging the position state of the transmitting coil, wherein the judgment can be specifically carried out according to the preset corresponding relation between the charging circuit parameter and the position state of the transmitting coil;
s120: judging whether the state is the third state C, if so, continuing to step S130: it is determined as the third state C that the transmitting coil is already within the optimal charging position range of the receiving coil, and then proceeds to step S210: displaying an indication signal corresponding to the third state, for example, displaying a green color when the annular LED indicator lamp is normally on, and indicating that the user does not need to move the charging patch before the charging is completed, so that the optimal charging efficiency can be obtained;
if not, continue to step S140: judging whether the state is the second sub-state B2 of the second state, if yes, continuing to the step S150: a second sub-state B2 determined as a second state, i.e. the distance outside the optimal charging position range of the transmitting coil and the receiving coil is greater than 0 and less than or equal to n1, the step S220 is continued: a second sub-state B2 corresponding to an indication signal showing a second state, e.g. a ring LED indicator showing green and flashing at a frequency, which may be 0.05-10 Hz;
if not the second substate B2, then the method continues with step S160: it is determined whether it is the first sub-state B1 of the second state, and if so, it continues to step S170: the first sub-state B1 determined as the second state, i.e. the distance outside the optimal charging position range of the transmitting coil and the receiving coil is greater than n1 and less than n2, continues with step S230: an indication signal corresponding to a first sub-state B1 showing a second state, for example, a ring LED indicator light showing green and flashing at a frequency, which may be 0.05-10 Hz;
if it is not the first sub-state B1 of the second state, proceed to step S180: it is determined as the first state a that the distance of the transmitting coil from the optimum charging position range is equal to or greater than n2, and the step S240 is continued: an indication signal corresponding to the first state is displayed indicating that the user is not currently detecting the receiving coil, e.g. the ring LED indicator light is displayed green and flashes at a frequency, which may be 0.05-10 Hz.
In this embodiment, the blinking frequencies of the indication signals corresponding to the first state a, the first sub-state B1 and the second sub-state B2 are different to distinguish the different indication signals, and whether the user is about to approach the optimal charging position range is indicated by the change of the blinking frequency. For example, the blinking frequency of the indication signal corresponding to the first state a, the first sub-state B1, and the second sub-state B2 gradually increases. The indication signal of the first state a is flashed for 1 second and 4 seconds with 5 seconds as a cycle. The indication signal of the first sub-state B1 in the second state is flashing for 2 seconds, 2 seconds bright and 2 seconds dark in a cycle of 4 seconds. The indication signal of the second sub-state B2 in the second state is flashing for 1 second, bright for 1 second, and dark for 1 second in a cycle of 2 seconds. In another embodiment, the blinking frequency of the indication signal corresponding to the first state a, the first sub-state B1 and the second sub-state B2 may be gradually decreased. Or the indication signals corresponding to the various position states adopt different display colors and are distinguished by different colors. The third state C may also be in another display color, or may be set to blink very brightly, and the blinking frequency may be different from that of the other position states.
In another embodiment, the audio indication signal is output through a speaker and/or a buzzer, the indication signals of the respective position states are distinguished through the difference of the output frequency of the buzzer, for example, the audio frequency of the indication signals of the first state a, the first sub-state B1 and the second sub-state B2 is gradually increased or gradually decreased, and the third state C also has a different audio frequency. Or, the display screen outputs visual indication signals, the indication signals of the various position states are distinguished by controlling the display screen to display different characters, images, animations and/or flashing frequencies, and the third state C also has different display contents. Alternatively, the indication signals of the first state a, the first sub-state B1 and the second sub-state B2, for example, the indication signals of the first state a, the first sub-state B1 and the second sub-state B2, are differentiated by controlling different vibration frequencies of the vibrator, and the third state C also has different vibration frequencies. Or outputting voice indication signals through a loudspeaker, and adopting different pre-recorded voices for different position states. Here, the audio frequency may include a frequency of the sound itself and/or a rhythm of the sound beep. The vibration frequency may comprise the vibration frequency and/or the vibration rhythm of the vibrator itself.
Since in this embodiment, the second state is further divided into the first sub-state B1 farther from the optimum charging position range and the second sub-state B2 closer. Through the switching of the position indication signal between the indication signal of the first sub-state B1 and the indication signal of the second sub-state B2, the user can be indicated that the charging patch is far away from or close to the optimal charging position range, so that the direction of the charging patch can be adjusted, and the optimal charging position range for wireless charging can be found more conveniently and quickly.
The first working state indicating module and the second working state indicating module can display different charging states. During the charging process, the first working state indicating module (such as an LED indicating ring at the cable socket interface) is displayed in red. After the charging is completed, the first working state indicating module is displayed in green. Synchronously, the charging status may be displayed at a second operating status indicating module of the charging device host, including but not limited to a display screen, an indicator light, a buzzer, a speaker, a vibrator, etc. The first working state indicating module and/or the second working state indicating module can also be used for indicating whether the charging patch can be normally used or not, and if the charging patch does not need to be used, the damaged state of the charging patch and whether the damaged reason is the damage of the transmitting coil or the damage of the indicating module can be indicated.
