一种塑形磁刺激仪A plastic magnetic stimulator

技术领域technical field

本发明涉及塑形磁技术领域，尤其涉及一种实时监测刺激肌肉状态并自适应调节刺激强度的塑形磁刺激仪。The invention relates to the technical field of shaping magnetism, in particular to a shaping magnetic stimulator which can monitor the state of a stimulated muscle in real time and adjust the stimulation intensity adaptively.

背景技术Background technique

目前主流的塑形技术包括药物治疗、电刺激、磁刺激。其中药物治疗因为较强的副作用越来越引起人们的警惕，而近年来兴起的电刺激和磁刺激技术因为其效果明显且见效快而越来越受到推崇。The current mainstream shaping techniques include drug therapy, electrical stimulation, and magnetic stimulation. Among them, drug therapy has attracted more and more people's vigilance because of its strong side effects. In recent years, the electric stimulation and magnetic stimulation technology that has emerged in recent years has been more and more respected because of its obvious effect and quick effect.

相比于目前使用较多的电刺激塑形技术，磁刺激塑形技术有以下三个方面的优势：1、刺激没有电流密度十分集中的区域，因此受试者无疼痛感；2、肌肉、骨骼等不良导体对磁脉冲进入人体没有衰减作用，因此磁刺激可以达到深部组织，特别是塑形磁刺激用户目标部位通常有较厚的脂肪层，对电流的衰减作用十分大，而磁刺激可以透过脂肪层直达目标肌肉，达到更好的塑形效果；3、磁刺激的操纵十分简单，只需将刺激线圈放在目标刺激部位旁边，中间可以有各种衣服，线圈位置方便改变。Compared with the current electric stimulation shaping technology, the magnetic stimulation shaping technology has the following three advantages: 1. The stimulation does not have a very concentrated area of current density, so the subjects have no pain; 2. Muscle, Bad conductors such as bones have no attenuation effect on the magnetic pulse entering the human body, so the magnetic stimulation can reach deep tissues, especially the target part of the shaping magnetic stimulation user usually has a thicker fat layer, which has a great attenuation effect on the current, while the magnetic stimulation can It can reach the target muscle directly through the fat layer to achieve better shaping effect; 3. The operation of magnetic stimulation is very simple, just place the stimulation coil next to the target stimulation site, there can be various clothes in the middle, and the position of the coil can be easily changed.

但是，目前磁刺激塑形领域还没有实时监测刺激肌肉状态的技术方案，处于“盲刺”的阶段，对于刺激部位的准确性和效果完全靠用户的口头反馈，无可量化的指标用来指示肌肉是否进入最大收缩状态、以及治疗过程中肌肉是否进入疲劳状态。因此治疗过程中耐受强度均是依靠询问用户体验感或者是全部调节强度至最大，无法确保每次都达到肌肉最大收缩状态，也就无法确保每次治疗效果最大化，并且无法针对治疗过程中用户可能出现的肌肉疲劳状态来调节强度，因此治疗过后，用户会普遍出现肌肉酸痛。However, at present, there is no technical solution for real-time monitoring of the state of stimulated muscles in the field of magnetic stimulation and shaping, and it is in the stage of "blind stab". The accuracy and effect of the stimulation site are completely dependent on the user's oral feedback, and there is no quantifiable index to indicate. Whether the muscle has entered a state of maximum contraction, and whether the muscle has entered a state of fatigue during the treatment. Therefore, the tolerance intensity during the treatment process depends on asking the user's experience or adjusting the intensity to the maximum. It is impossible to ensure that the maximum muscle contraction state is reached every time, and it is impossible to ensure the maximum effect of each treatment. The user may have muscle fatigue to adjust the intensity, so after the treatment, the user will generally experience muscle soreness.

为解决上述问题，本发明公开了一种实时监测刺激肌肉状态并自适应调节刺激强度的塑形磁刺激仪。In order to solve the above problems, the present invention discloses a shaping magnetic stimulator that monitors the state of the stimulated muscles in real time and adaptively adjusts the stimulation intensity.

具体实施方式Detailed ways

下面结合附图和实施例对本发明的技术方案做进一步的详细说明。The technical solutions of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

如图1和图2所示，本发明实施例公开了一种塑形磁刺激仪，包括肌肉状态监测模块2、控制运算模块3、通信模块、可视化终端4和刺激线圈1；其中刺激线圈1为跑道型绕制，肌肉状态监测模块2用于实时采集磁刺激状态下的肌肉状态值；控制运算模块3的输入端与肌肉状态监测模块2相连，用于接收肌肉状态监测模块2采集的肌肉状态值并转成肌力特征值，通过调节磁刺激强度，根据肌力特征值的变化与目标肌肉收缩状态的理论关系自适应调节磁刺激强度；控制运算模块3的输出端与刺激线圈1相连，刺激线圈1根据控制运算模块3发送的电磁波刺激参数作用于目标肌肉。As shown in FIG. 1 and FIG. 2, an embodiment of the present invention discloses a shaping magnetic stimulator, including a musclestate monitoring module 2, a controlarithmetic module 3, a communication module, avisualization terminal 4 and astimulation coil 1; wherein thestimulation coil 1 It is a runway type winding, and the musclestate monitoring module 2 is used to collect the muscle state value under the magnetic stimulation state in real time; The state value is converted into a muscle strength characteristic value, and by adjusting the magnetic stimulation intensity, the magnetic stimulation intensity is adaptively adjusted according to the theoretical relationship between the change of the muscle strength characteristic value and the target muscle contraction state; the output end of thecontrol operation module 3 is connected to thestimulation coil 1 , thestimulation coil 1 acts on the target muscle according to the electromagnetic wave stimulation parameters sent by thecontrol operation module 3 .

图3至图5示出本发明实施例现有圆形线圈103，跑道型线圈101与中空跑道型线圈102 的结构示意图及磁场分布情况，具体的中空跑道型线圈102与跑道型线圈101的结构区别在于线圈只沿跑道两侧绕制。以高度2cmX轴方向和Y轴方向-140mm至+140mm磁场变化显示，圆形线圈103的磁场分布尖而窄，跑道型线圈101的磁场分布扁而宽，中空跑道型线圈102的磁场分布相比较跑道型线圈略窄，但比现有的圆形线圈103的磁场分布宽。因此，跑道型线圈101与中空跑道型线圈102的结构设计均能实现更宽的磁场分布。3 to 5 show the structure schematic diagram and magnetic field distribution of the conventionalcircular coil 103 , theracetrack coil 101 and thehollow racetrack coil 102 according to the embodiments of the present invention, and the specific structures of thehollow racetrack coil 102 and theracetrack coil 101 The difference is that the coils are wound only along both sides of the track. The magnetic field distribution in the X-axis direction and the Y-axis direction at a height of 2 cm from -140 mm to +140 mm shows that the magnetic field distribution of thecircular coil 103 is sharp and narrow, the magnetic field distribution of theracetrack coil 101 is flat and wide, and the magnetic field distribution of thehollow racetrack coil 102 is compared. The racetrack coil is slightly narrower, but has a wider magnetic field distribution than the conventionalcircular coil 103 . Therefore, the structure design of theracetrack coil 101 and thehollow racetrack coil 102 can both achieve wider magnetic field distribution.

如图6至图8所示，针对不同体型采用同样的磁场对于体型偏瘦者的刺激面太大，对于体型偏胖者刺激面太小。为适应不同体型的用户，本发明进一步将跑道绕制的刺激线圈1设计成弧形结构，正反两个刺激面的磁刺激强度及磁场分布均不同。弧形结构的跑道型线圈或中空跑道型线圈凹面刺激面广，磁场分布宽而广，如图7两侧颜色较深的区域所示，主要集中在刺激线圈的两端部位置；而凸面刺激面窄，如图8中间区域所示，主要集中在刺激线圈的中部，磁场强度高，具有聚磁效果。As shown in Fig. 6 to Fig. 8 , using the same magnetic field for different body types has too much stimulation surface for thin people, and too small stimulation surface for obese people. In order to adapt to users of different body shapes, the present invention further designs thestimulation coil 1 wound by the track into an arc-shaped structure, and the magnetic stimulation intensity and magnetic field distribution of the positive and negative stimulation surfaces are different. The arc-shaped racetrack coil or hollow racetrack coil has a wide concave stimulation surface and a wide and wide distribution of the magnetic field, as shown in the darker areas on both sides of Figure 7, which are mainly concentrated at the two ends of the stimulation coil; while the convex stimulation The surface is narrow, as shown in the middle area of Fig. 8, mainly concentrated in the middle of the stimulation coil, with a high magnetic field strength and a magnetic focusing effect.

在实际应用中，当作用于腹部肌肉时，由于分娩或其他原因导致腹直肌分离，采用凹面刺激面进行刺激时，位于腹白线处无肌肉，无需进行磁刺激，磁场主要集中在腹白线两侧的肌肉，从而实现更好的治疗效果。因此，弧形结构跑道型线圈或弧形结构中空跑道型线圈可针对用户对磁刺激强度及用户体型需求选择使用刺激线圈的凸面或凹面作用于目标肌肉，保证更好的磁刺激效果。In practical applications, when acting on the abdominal muscles, the rectus abdominis is separated due to childbirth or other reasons. When the concave stimulation surface is used for stimulation, there is no muscle located at the linea alba, and no magnetic stimulation is required. The magnetic field is mainly concentrated in the white line of the abdomen Muscles on both sides of the line for better treatment results. Therefore, the arc-shaped track-shaped coil or the arc-shaped hollow track-shaped coil can choose to use the convex or concave surface of the stimulation coil to act on the target muscle according to the user's demand for magnetic stimulation intensity and user body shape, so as to ensure a better magnetic stimulation effect.

由图9所示，平面线圈两面的磁场分布相同，但当平面线圈压制成弧形，其凹面的磁场分布即发生变化，根据麦克斯韦方程

Γ为曲面Ω的边界，J为传导电流密度矢量，

为位移电流密度(A/m2)，D为电通密度(C/m2)，同一个线圈等式右边一样，左边dL减少H就会变大，对于线圈边缘参考B至刺激点的距离大于线圈边缘参考 A，进一步证实弧形结构的刺激线圈的凹面具有聚磁效果。As shown in Figure 9, the magnetic field distribution on both sides of the planar coil is the same, but when the planar coil is pressed into an arc shape, the magnetic field distribution on the concave surface changes. According to Maxwell's equation

Γ is the boundary of the surface Ω, J is the conduction current density vector,

is the displacement current density (A/m2), D is the electric flux density (C/m2), the same as the right side of the same coil equation, the left dL decreases H will become larger, for the coil edge, the distance from B to the stimulation point is greater than the coil Refer to A for the edge, which further confirms that the concave surface of the stimulation coil of the arc-shaped structure has a magnetic concentrating effect.

在一实施例中，跑道型线圈101或中空跑道型线圈102的内径尺寸为30*50～80*100mm，外径尺寸为80*100～200*220mm，线圈的圈数根据性能指标具体定制，采用编制铜线制作、铜线与铜线之间采用环氧树脂灌封粘接。在跑道型线圈101或中空跑道型线圈102的基础上进行弧度处理，形成凹刺激面和凸刺激面两个不同磁刺激强度的刺激面，即可满足不同体型人群的磁刺激需求。In one embodiment, the inner diameter of theracetrack coil 101 or thehollow racetrack coil 102 is 30*50～80*100mm, and the outer diameter is 80*100～200*220mm, and the number of turns of the coil is customized according to the performance index. It is made of braided copper wire, and epoxy resin potting is used between the copper wire and the copper wire. On the basis of theracetrack coil 101 or thehollow racetrack coil 102, radian processing is performed to form two stimulation surfaces with different magnetic stimulation intensities, a concave stimulation surface and a convex stimulation surface, which can meet the magnetic stimulation needs of people of different body sizes.

进一步说明，肌肉状态监测模块2用于实时采集磁刺激目标肌肉5收缩状态，采集的信号可以为皮肤表面肌电信号，或使用压力传感器和流体装置采集的压力信号，或基于机械波 (频率在10Hz～1010Hz)或电磁波(频率在10Hz～1020Hz)的采集的皮肤表面图像信号，从而实现实时监测目标肌肉状态的目的。Further description, the musclestate monitoring module 2 is used to collect the contraction state of the magneticstimulation target muscle 5 in real time, and the collected signal can be a skin surface electromyography signal, or a pressure signal collected by a pressure sensor and a fluid device, or based on a mechanical wave (frequency at 10Hz). ～1010Hz) or electromagnetic wave (frequency between 10Hz～1020Hz) collected skin surface image signal, so as to achieve the purpose of real-time monitoring of the target muscle state.

在一实施例中，如图10所示，肌肉状态监测模块2包括流体结构及安装在流体结构内的压力传感器，流体结构安装在刺激线圈1的正反刺激面上，如气囊机构，其内填充有气体或液体，当刺激线圈1磁刺激目标肌肉，压力传感器采集目标肌肉在被磁刺激时形变引起气体或液体变化的压力信号，即为肌肉状态值或肌力值。In one embodiment, as shown in FIG. 10 , the musclestate monitoring module 2 includes a fluid structure and a pressure sensor installed in the fluid structure, and the fluid structure is installed on the positive and negative stimulation surfaces of thestimulation coil 1, such as an airbag mechanism, in which Filled with gas or liquid, when thestimulation coil 1 magnetically stimulates the target muscle, the pressure sensor collects the pressure signal of the gas or liquid change caused by the deformation of the target muscle when it is magnetically stimulated, which is the muscle state value or muscle strength value.

或者，肌肉状态监测模块2还可为贴于目标肌肉5对应部位的采集电极，刺激线圈1磁刺激目标肌肉时，电流经过神经通路传递到目标肌肉，目标肌肉5产生动作即可采集到皮肤表面肌电信号。基于采集到的肌电信号转化成肌力特征值，在通过调节磁刺激强度，通过肌力特征值的变化情况，自适应的调节磁刺激强度。Alternatively, the musclestate monitoring module 2 can also be a collection electrode attached to the corresponding part of thetarget muscle 5. When thestimulation coil 1 magnetically stimulates the target muscle, the current is transmitted to the target muscle through the nerve pathway, and thetarget muscle 5 can generate motion to collect the skin surface. EMG signal. Based on the conversion of the collected EMG signals into muscle strength characteristic values, the magnetic stimulation intensity is adaptively adjusted by adjusting the magnetic stimulation intensity and through the changes of the muscle strength characteristic values.

或者，肌肉状态监测模块2还可采用红外传感器、激光传感器或超声波传感器等采集目标肌肉产生形变的图像信号，如超声成像、可见光成像、红外、微波成像、X线成像、X-CT成像、磁共振成像、核素成像、分子成像等。同样，基于图像信号转化成肌力特征值。Alternatively, the musclestate monitoring module 2 may also use an infrared sensor, a laser sensor or an ultrasonic sensor to collect image signals of the deformation of the target muscle, such as ultrasonic imaging, visible light imaging, infrared, microwave imaging, X-ray imaging, X-CT imaging, magnetic Resonance imaging, nuclide imaging, molecular imaging, etc. Likewise, the image-based signal is converted into a muscle strength feature value.

控制运算模块3包括信号处理单元和单片机，信号处理单元用于对肌肉状态监测模块2 采集的信号进行处理，消除信号中的噪声和干扰，将肌电信号或压力信号或图像信号变换成单片机容易处理和识别的肌力特征值；单片机接收、储存、并处理肌力特征值，实现强度自适应调节算法，根据肌力特征值计算出实时最优刺激强度，并传递磁刺激参数和用户状态给可视化终端4；单片机已实现但不限于STM32、GD32。Thecontrol operation module 3 includes a signal processing unit and a single-chip microcomputer. The signal processing unit is used to process the signal collected by the musclestate monitoring module 2, eliminate noise and interference in the signal, and convert the EMG signal or pressure signal or image signal into a single-chip microcomputer easily. The muscle strength characteristic value processed and identified; the single-chip computer receives, stores, and processes the muscle strength characteristic value, realizes the intensity adaptive adjustment algorithm, calculates the real-time optimal stimulation intensity according to the muscle strength characteristic value, and transmits the magnetic stimulation parameters and user status to the user.Visualization terminal 4; SCM has been implemented but not limited to STM32, GD32.

根据肌肉收缩过程中的肌电特征值，能够更直观地评估指示磁场强度是否引起肌肉最大收缩，保证每一次治疗效果最大化。本发明的肌力特征值为脉冲持续时间内所有肌肉状态值的平均值、中位数、平均振幅值、积分肌电值、均方根平均功率频率值、中位频率值、信号上升或下降通过零线的比率、协同收缩率的一种或多种组合计算而成。通常情况下，肌力特征值为磁脉冲持续时间内所有肌肉状态值，即肌力值的平均值，或平均值与中位数或平均振幅值或其他的结合运算。According to the EMG characteristic value in the process of muscle contraction, it is possible to more intuitively evaluate whether the indicated magnetic field strength causes the maximum contraction of the muscle, so as to ensure the maximum effect of each treatment. The muscle strength characteristic value of the present invention is the average value, median value, average amplitude value, integral EMG value, RMS average power frequency value, median frequency value, signal rise or fall of all muscle state values within the pulse duration Calculated by one or more combinations of the ratio of the zero line and the synergistic shrinkage rate. Usually, the muscle strength characteristic value is the average value of all muscle state values during the duration of the magnetic pulse, that is, the average value of the muscle strength value, or the combination of the average value and the median or average amplitude value or others.

通信模块用于连接单片机、可视化终端4和刺激线圈1。目前可实现有线(包括但不限于STD和CAMAC总线、ISA总线、VXI总线、PCI、Compact及PXI总线、RS-232C、RS-422A、 RS-485、USB、IEEE-1943、IEEE488、SCSI总线、MXI总线)和无线(包括但不限于自定义协议、IEEE802.15.4协议、ZigBee协议、蓝牙协议、LoRa以及UWB通信方式)的方式连接。The communication module is used to connect the single chip microcomputer, thevisualization terminal 4 and thestimulation coil 1. Wired (including but not limited to STD and CAMAC bus, ISA bus, VXI bus, PCI, Compact and PXI bus, RS-232C, RS-422A, RS-485, USB, IEEE-1943, IEEE488, SCSI bus, MXI bus) and wireless (including but not limited to custom protocol, IEEE802.15.4 protocol, ZigBee protocol, Bluetooth protocol, LoRa and UWB communication methods) way to connect.

可视化终端4用于图形化显示实时肌力曲线、肌肉收缩时的肌力特征值、磁刺激参数等。Thevisualization terminal 4 is used to graphically display the real-time muscle strength curve, the muscle strength characteristic value during muscle contraction, the magnetic stimulation parameters, and the like.

刺激线圈1根据单片机发射的磁脉冲刺激参数作用于目标肌肉、神经肌肉或肌纤维，以达到塑形效果。刺激线圈1将磁脉冲刺激作用于人体目标肌肉，包括磁刺激频率、强度、脉冲数、间隔、时长等参数。Thestimulation coil 1 acts on the target muscle, neuromuscular or muscle fiber according to the magnetic pulse stimulation parameters transmitted by the single-chip microcomputer, so as to achieve the shaping effect. Thestimulation coil 1 applies magnetic pulse stimulation to the target muscles of the human body, including parameters such as magnetic stimulation frequency, intensity, pulse number, interval, and duration.

但在塑形过程中，磁刺激强度过低，目标肌群无法实现最大收缩，则达不到较好的塑形效果；磁刺激强度过高，导致用户进入疲劳状态，则可能产生痛感，甚至肌肉痉挛。因此，自动找到最适合用户的磁刺激强度对于提高治疗效果和提高体验至关重要。However, during the shaping process, if the magnetic stimulation intensity is too low, the target muscle group cannot achieve the maximum contraction, and a good shaping effect cannot be achieved; if the magnetic stimulation intensity is too high, the user may enter a state of fatigue, which may cause pain, or even Muscle spasms. Therefore, automatically finding the most suitable magnetic stimulation intensity for the user is crucial to improve the therapeutic effect and enhance the experience.

为解决这一问题，作为本发明的一实施例，实时采集磁刺激状态下的肌力特征值P(t)，调节磁刺激强度，根据临床实验肌力特征值与肌肉收缩状态的理论关系自适应调节刺激强度，从而使得用户在每一时刻都能接收到最合适当前肌力的磁刺激强度，提高治疗效果。In order to solve this problem, as an embodiment of the present invention, the muscle strength characteristic value P(t) under the magnetic stimulation state is collected in real time, and the magnetic stimulation intensity is adjusted. According to the theoretical relationship between the muscle strength characteristic value and the muscle contraction state in clinical experiments, Adjust the stimulation intensity adaptively, so that the user can receive the magnetic stimulation intensity most suitable for the current muscle strength at every moment, and improve the treatment effect.

具体的，如图11至图12所示，实现塑形磁刺激仪实时监测刺激肌肉状态并自适应调节刺激强度的具体方法为：Specifically, as shown in Fig. 11 to Fig. 12, the specific method for realizing the real-time monitoring of the stimulated muscle state by the shaping magnetic stimulator and adaptively adjusting the stimulation intensity is as follows:

记录目标肌肉在t时刻的肌力特征值；用户进入塑形阶段，根据塑形方案(Treatment_No)，塑形磁刺激仪发射相对应电磁波，包括频率(Treatment_No_Freq)、强度(Treatment_No_Stren(t))、脉冲数(Treatment_No_Cycle)、间隔(Treatment_No_Gap)、时长(Treatment_No_Dura)。Record the muscle strength characteristic value of the target muscle at time t; the user enters the shaping stage, and according to the shaping plan (Treatment_No), the shaping magnetic stimulator emits corresponding electromagnetic waves, including frequency (Treatment_No_Freq), intensity (Treatment_No_Stren(t)), Number of pulses (Treatment_No_Cycle), interval (Treatment_No_Gap), duration (Treatment_No_Dura).

基于采集到的肌肉状态值即肌力值，计算出每个治疗脉冲的肌力特征值P_Eig(k)。经过实验和对比，本发明使用复杂度和效果均较好的平均值指标，即肌力特征值P_Eig(k)为单位脉冲持续时间内所有肌力值的平均值，同时基于临床实验肌力特征值与肌肉收缩状态的理论关系自适应调节刺激强度。Based on the collected muscle state value, that is, the muscle strength value, the muscle strength characteristic value P_Eig(k) of each treatment pulse is calculated. After experiments and comparisons, the present invention uses an average index with better complexity and effect, that is, the muscle strength characteristic value P_Eig(k) is the average value of all muscle strength values within the unit pulse duration, and is based on clinical experimental muscle strength characteristics. The theoretical relationship between the value and the state of muscle contraction adaptively modulates the stimulus intensity.

若调高磁刺激强度，P_Eig(k)持续增大，则认为肌肉未达到最大收缩状态，调高下一时刻磁刺激强度为：If the magnetic stimulation intensity is increased and P_Eig(k) continues to increase, it is considered that the muscle has not reached the maximum contraction state, and the magnetic stimulation intensity at the next moment is:

Treatment_No_Stren(t+1)＝Treatment_No_Stren(t)*(1+Stren_Tune)Treatment_No_Stren(t+1)=Treatment_No_Stren(t)*(1+Stren_Tune)

其中，Stren_Tune为微调系数，取值区间为：[0,1]，通常取值5％。Among them, Stren_Tune is the fine-tuning coefficient, the value range is: [0, 1], usually the value is 5%.

若调高磁刺激强度，P_Eig(k)基本不变，则认为肌肉已经达到最大收缩状态，取上一磁刺激强度为最优磁刺激强度：If the magnetic stimulation intensity is increased, P_Eig(k) is basically unchanged, it is considered that the muscle has reached the maximum contraction state, and the last magnetic stimulation intensity is taken as the optimal magnetic stimulation intensity:

若刺激过程中，磁刺激强度不变，P_Eig(k)下降，则认为肌肉已经进入疲劳状态，则降低下一时刻磁刺激强度为：If during the stimulation process, the magnetic stimulation intensity remains unchanged and P_Eig(k) decreases, it is considered that the muscle has entered a state of fatigue, and the magnetic stimulation intensity at the next moment is reduced as follows:

Treatment_No_Stren(t+1)＝Treatment_No_Stren(t)*(1-Stren_Tune)Treatment_No_Stren(t+1)=Treatment_No_Stren(t)*(1-Stren_Tune)

其中，Stren_Tune为微调系数，取值区间为：[0,1]，通常取值5％-10％。Among them, Stren_Tune is the fine-tuning coefficient, the value range is: [0, 1], usually the value is 5%-10%.

图13至图14进一步说明塑形过程中随刺激强度的变化与肌力特征值之间的关系。Figures 13 to 14 further illustrate the relationship between the change with the stimulus intensity and the muscle strength characteristic value during the shaping process.

在0s至100s阶段，为用户自主呼吸状态，不接受磁刺激，肌力图显示用户呼吸时的肌力状态值。In the stage from 0s to 100s, the user is in the state of spontaneous breathing and does not receive magnetic stimulation.

在100s至440s阶段，随着磁刺激强度的增加，用户的肌力状态值和肌力特征值处于稳步增加的状态，则下一时刻磁刺激强度为上一时刻磁刺激强度的基础上适度增加磁刺激强度。From 100s to 440s, with the increase of the magnetic stimulation intensity, the user's muscle strength state value and muscle strength characteristic value are in a state of steady increase, then the magnetic stimulation intensity at the next moment will be moderately increased on the basis of the magnetic stimulation strength at the previous moment. Magnetic stimulation intensity.

450s往后阶段，在磁刺激强度不变的情况下，用户的肌力状态值和肌力特征值有所下降，显示目标肌肉有所疲劳，则下一时刻磁刺激强度为上一时候磁刺激强度的基础上适度降低刺激强度，使得目标肌肉仍处于最佳刺激状态。保证刺激强度的同时降低目标肌肉的疲劳，加速刺激后的恢复，提高塑形效果。In the later stage of 450s, when the magnetic stimulation intensity remains unchanged, the user's muscle strength state value and muscle strength characteristic value decrease, indicating that the target muscle is fatigued, and the magnetic stimulation intensity at the next moment is the magnetic stimulation at the previous time. On the basis of the intensity, the stimulation intensity is moderately reduced, so that the target muscle is still in the best stimulation state. While ensuring the stimulation intensity, it reduces the fatigue of the target muscles, accelerates the recovery after stimulation, and improves the shaping effect.

在整个塑形过程中，实时采集肌肉收缩过程中的肌肉状态值，并转化成相对应的肌力特征值，根据肌肉收缩过程中肌力特征值的变化判定刺激过程中肌肉收缩程度，能够更直观地评估指示磁场强度是否引起肌肉最大收缩或已进入疲劳状态，从而自适应调整刺激强度，此过程为治疗过程中持续监测并不断调整的过程，保证每一次治疗效果最大化。相比于现有的自适应调节刺激强度技术，本发明提出自适应调节算法不需要使用神经网络、深度学习等非解析类方法建模，不需要前期花费大量资源训练模型拟合参数，采用临床经验总结出的计算方法，成本大幅降低，更加简洁、更为直观、能很好的提高塑形效果。During the whole shaping process, the muscle state value during the muscle contraction process is collected in real time, and converted into the corresponding muscle strength characteristic value. Intuitively assess whether the indicated magnetic field strength causes the muscle to contract the maximum or has entered a state of fatigue, so as to adjust the stimulation intensity adaptively. This process is a process of continuous monitoring and continuous adjustment during the treatment process to ensure the maximum effect of each treatment. Compared with the existing self-adaptive adjustment stimulation intensity technology, the self-adaptive adjustment algorithm proposed in the present invention does not need to use non-analytical methods such as neural network and deep learning for modeling, and does not need to spend a lot of resources in the early stage to train model fitting parameters. The calculation method summed up by experience has greatly reduced the cost, is more concise, more intuitive, and can improve the shaping effect.
