At present, in order to exercise the respiratory function of mechanically ventilated patients, doctors usually reduce the intensity of mechanical ventilation and increase the respiratory load of patients based on their own experience. This method cannot refer to the actual tolerance of the patient, and it is easy to cause human-machine confrontation, resulting in lung injury, which is not conducive to the recovery of the patient.
因此，为了保证患者安全、高效呼吸，降低肺损伤的发生风险，如何提供一种安全、高效、智能，促进自主呼吸能力恢复的肺康复训练系统是本领域技术人员亟需解决的问题。Therefore, in order to ensure the safe and efficient breathing of patients and reduce the risk of lung injury, how to provide a safe, efficient, intelligent pulmonary rehabilitation training system that can promote the recovery of spontaneous breathing ability is an urgent problem for those skilled in the art to solve.

Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
请参照附图1，本实用新型提供了一种基于呼吸肌电信号反馈的肺康复训练系统，包括控制器2，其特征在于：还包括与控制器2连接的电磁换向阀10、流量传感器11，以及通过放大电路4与控制器2连接的电极5；Please refer to accompanying drawing 1, the utility model provides a kind of pulmonary rehabilitation training system based on respiratory myoelectric signal feedback, comprises controller 2, is characterized in that: also comprises the electromagnetic reversing valve 10 that is connected with controller 2, flow sensor 11, and the electrode 5 connected to the controller 2 through the amplifier circuit 4;
其中电磁换向阀10一路通过流量传感器11连通至气道接口12；另外两路分别连通有压力比例调节阀A9、压力比例调节阀B15，并且电磁换向阀10在两路中进行切换选择；Among them, one path of the electromagnetic reversing valve 10 is connected to the airway interface 12 through the flow sensor 11; the other two paths are respectively connected with the pressure proportional regulating valve A9 and the pressure proportional regulating valve B15, and the electromagnetic reversing valve 10 is switched between the two paths;
本实用新型提供的肺康复训练系统可以实现高强度和低强度肺康复训练过程，可通过控制器2控制电磁换向阀10在医用正压气源8和医用负压气源13的两个支路间的切换，达到了两种不同训练强度的自由选择的目的，使患者可以依据自身病情和恢复情况选择康复训练强度。并且控制器2可以根据呼吸肌电信号，采用智能算法，如神经网络、模糊、专家，等智能算法，提取出患者咳嗽要开始咳嗽的信号特征，并量化患者预期的咳嗽强度。The pulmonary rehabilitation training system provided by the utility model can realize the high-intensity and low-intensity pulmonary rehabilitation training process, and the electromagnetic reversing valve 10 can be controlled by the controller 2 in the two branches of the medical positive pressure air source 8 and the medical negative pressure air source 13.

本实用新型提供的肺康复训练系统不仅可以达到恢复训练的技术效果，同时还可以作为机械通气的呼吸机使用。由于肺康复训练是周期性的，间断的训练过程，因此，在患者进行训练之外的时间还需要通过呼吸机辅助呼吸，以缓解训练负荷。本实用新型通过电磁换向阀10和压力比例调节阀B15的配合可以达到这一目的。The pulmonary rehabilitation training system provided by the utility model can not only achieve the technical effect of recovery training, but also can be used as a ventilator for mechanical ventilation.

需要说明的是，流量传感器11对患者呼吸流量的测量采用差压式流量计的测量原理：即，基于流体的机械能相互转换的原理。在水平管道中流动的流体，具有动压能和静压能(位能相等)，在一定条件下，这两种形式的能量可以相互转换，但能量总和不变。差压流量计的通用计算公式如下所示，由式(1)推导可得到式(2)。It should be noted that the measurement principle of the flow sensor 11 for the respiratory flow of the patient adopts the measurement principle of the differential pressure flowmeter: that is, the principle based on the mutual conversion of the mechanical energy of the fluid. The fluid flowing in the horizontal pipeline has dynamic pressure energy and static pressure energy (equal potential energy). Under certain conditions, these two forms of energy can be converted into each other, but the sum of energy remains unchanged. The general calculation formula of the differential pressure flowmeter is shown below, and the formula (2) can be derived from the formula (1).
式中Q代表流量，△P代表差压，ρ代表流体密度，K是仪表系数，通过测试来标定得到。In the formula, Q represents the flow rate, △P represents the differential pressure, ρ represents the fluid density, and K is the instrument coefficient, which is obtained through calibration through testing.

下面对本实用新型的工作原理进行详细说明：The working principle of the present utility model is described in detail below:
在肺康复训练过程中，控制器2控制压力比例调节阀A9、压力比例调节阀B15的输出压力。During the pulmonary rehabilitation training, the controller 2 controls the output pressures of the pressure proportional regulating valve A9 and the pressure proportional regulating valve B15.
其中，在低强度训练时，吸气过程为：电磁换向阀10置上位，控制器2根据呼吸肌电信号实时调节压力比例调节阀A9的输出压力，适当降低输出的压力，但仍需保证经压力比例调节阀A9调节后的管路中的气压高于大气压，协助患者的吸气过程，将医用正压气源中的气体送入患者肺部。呼气过程为：电磁换向阀10置下位，控制器2根据呼吸肌电信号实时调节压力比例调节阀B15的输出压力，并控制输出的压力低于大气压，协助患者将呼出的气体经流量传感器11、单向阀17排出至外部大气16中。本实用新型在低强度的训练过程中，电磁换向阀10处于频繁切换状态，且通过控制器2对患者呼吸肌信号的检测，保证切换频率与患者呼吸频率同步。Among them, during low-intensity training, the inhalation process is as follows: the electromagnetic reversing valve 10 is set to the upper position, and the controller 2 adjusts the output pressure of the pressure proportional regulating valve A9 in real time according to the respiratory myoelectric signal, and appropriately reduces the output pressure, but it still needs to be guaranteed. The air pressure in the pipeline adjusted by the pressure proportional regulating valve A9 is higher than the atmospheric pressure, assisting the patient's inhalation process, and sending the gas in the medical positive pressure air source into the patient's lungs. The exhalation process is as follows: the electromagnetic reversing valve 10 is set to the lower position, the controller 2 adjusts the output pressure of the pressure proportional regulating valve B15 in real time according to the respiratory myoelectric signal, and controls the output pressure to be lower than atmospheric pressure, assisting the patient to pass the exhaled gas through the flow sensor 11. The one-way valve 17 discharges to the external atmosphere 16 . In the low-intensity training process of the utility model, the electromagnetic reversing valve 10 is in a state of frequent switching, and the controller 2 detects the patient's respiratory muscle signal to ensure that the switching frequency is synchronized with the patient's respiratory frequency.
在高强度训练时，电磁换向阀10置下位，吸气过程为：控制器2根据呼吸肌电信号实时调节压力比例调节阀B15的输出压力，并控制输出的压力低于或等于大气压，当输出的压力等于大气压时，促使患者自主吸气；当输出的压力低于大气压时，患者克服管路中的低气压带来的阻力进行吸气，加大吸气负荷，协助患者肺吸气能力的锻炼。呼气过程无需切换电磁换向阀10的位置，同样将患者将呼出的气体经流量传感器11、单向阀17排出至外部大气16中。本实用新型在高强度的训练过程中，电磁换向阀10一直置于下位，呼吸过程无需进行切换。During high-intensity training, the electromagnetic reversing valve 10 is set to the lower position, and the inhalation process is: the controller 2 adjusts the output pressure of the pressure proportional regulating valve B15 in real time according to the respiratory myoelectric signal, and controls the output pressure to be lower than or equal to the atmospheric pressure. When the output pressure is equal to the atmospheric pressure, the patient is prompted to inhale spontaneously; when the output pressure is lower than the atmospheric pressure, the patient overcomes the resistance brought by the low air pressure in the pipeline to inhale, increases the inspiratory load, and assists the patient's lung inspiratory capacity workout. The exhalation process does not need to switch the position of the electromagnetic reversing valve 10 , and the gas exhaled by the patient is also discharged into the external atmosphere 16 through the flow sensor 11 and the one-way valve 17 . In the utility model, in the high-intensity training process, the electromagnetic reversing valve 10 is placed in the lower position all the time, and the breathing process does not need to be switched.
在肺康复训练间隙的机械通气过程中，控制器2根据电极5检测的呼吸肌电信号、流量传感器11和压力传感器B7检测到的呼吸气流流量、压力控制电磁换向阀10的位置以及压力比例调节阀A9的输出压力。当患者需要吸气时，电磁换向阀10置上位，压力比例调节阀A9输出的空气经电磁换向阀10、流量传感器11供给患者，此状态时向患者肺部通气气压大于低强度训练时的同期气压；患者需要呼气时，压力比例调节阀A9处于闭合状态，换向阀10置下位，患者呼出的空气经流量传感器11、电磁换向阀10、单向阀17流向大气16，参见附图1。During the mechanical ventilation process between pulmonary rehabilitation training, the controller 2 controls the position and pressure ratio of the electromagnetic reversing valve 10 according to the respiratory myoelectric signal detected by the electrode 5, the respiratory flow rate and pressure detected by the flow sensor 11 and the pressure sensor B7 Adjust the output pressure of valve A9. When the patient needs to inhale, the electromagnetic reversing valve 10 is set to the upper position, and the air output by the pressure proportional regulating valve A9 is supplied to the patient through the electromagnetic reversing valve 10 and the flow sensor 11. In this state, the air pressure to the patient's lungs is greater than that during low-intensity training. When the patient needs to exhale, the pressure proportional regulating valve A9 is in the closed state, the reversing valve 10 is set to the lower position, and the air exhaled by the patient flows to the atmosphere 16 through the flow sensor 11, the electromagnetic reversing valve 10, and the one-way valve 17, see Attached Figure 1.
