血管保健康复治疗系统 Vascular health rehabilitation system
【技术领域】 [Technical Field]
本发明涉及医疗仪器领域, 尤其是一种血管保健康复治疗系统。 【背景技术】 The invention relates to the field of medical instruments, in particular to a vascular health rehabilitation treatment system. 【Background technique】
近十余年新兴的血管医学研究证实, 提高血流速度 (反映血流剪切应力), 能调动血管内皮细胞的自我修复功能, 从而防止粥样硬化的发生与发展。 至 于如何提高血流速度和血流切应力, 过去从未受到注意。 Recent vascular medical research in more than a decade has confirmed that increasing blood flow velocity (reflecting blood flow shear stress) can mobilize the self-repairing function of vascular endothelial cells, thereby preventing the occurrence and development of atherosclerosis. As for how to increase blood flow velocity and blood flow shear stress, it has never been noticed in the past.
反搏装置可以用来提高血流速度。 反搏装置的原理是利用心电触发, 带 动充、 排气电磁阀的开、 关来实现气嚢的加压和排空, 从而达到通过反搏治 疗各种疾病的目的。 因此, 有效的反搏要求准确地在心脏的舒张期开始立即 充气, 让舒张压立即升高, 把血液更多灌入心肌、 大脑以及一切脏器; 进入 心脏收缩期后气嚢则要立即排空, 使人体下半身的压力解除, 血管张开以迎 纳心脏的射血, 由于血管张开、 收缩压下降, 心脏射血阻力下降, 心肌^ ί故功 可以减少, 耗氧也相应可以减少。 A counterpulsation device can be used to increase blood flow velocity. The principle of the counterpulsation device is to use the ECG trigger to drive the opening and closing of the charging and exhausting solenoid valves to achieve the pressure and evacuation of the air sputum, thereby achieving the purpose of treating various diseases by counterpulsation. Therefore, an effective counterpulsation requires accurate inflation immediately at the beginning of the diastolic phase of the heart, allowing the diastolic blood pressure to rise immediately, pouring more blood into the heart muscle, the brain, and all organs; Empty, the body's lower body pressure is relieved, the blood vessels open to meet the heart's ejection, due to the opening of the blood vessels, the systolic blood pressure drops, the heart ejection resistance decreases, the myocardial pressure can be reduced, and the oxygen consumption can be reduced accordingly.
上述的反搏过程使血流速度得以提升, 但是, 实践证明: 如何准确地充 气加压、 排气降压, 何时开始加压排压、 以及施加多大的反搏压力等, 组成 了反搏参数, 构成了影响反搏效果的关键因素。 The above-mentioned counterpulsation process improves the blood flow velocity, but it has been proved that: how to accurately inflate the pressure, depressurize the blood pressure, when to start the pressure discharge, and how much counter pressure to apply, etc. The parameters constitute the key factors affecting the counter-stroke effect.
现有反搏装置的反搏参数一般由操作者根据装置指示: 心电波、 排气标 志、 气源压力等主观因素自行设定。 并根据反搏时出现的指脉波图形, 按反 搏原理要求对充排气时间及气源压力进行调整至满意为止。 这种操作无疑是 不够科学的。 The counterpulsation parameters of the existing counterpulsation device are generally set by the operator according to the device indication: subjective factors such as electrocardiogram, exhaust gas mark, and air source pressure. According to the finger vein pattern appearing during the counterpulsation, the charging and exhausting time and the source pressure are adjusted to the satisfaction according to the principle of the counterpulsation. This kind of operation is undoubtedly not scientific enough.
申请人曾对 30 例自愿接受试验的冠心病患者在不同反搏压力下录取反 搏时脉波中舒张期增量波 (以下筒称 DA波), 并计算其 dv/dt斜率, 发现随着 反搏压力上升,他们的 DA波的 dv/dt渐增 (参见图 4), 其中 14例当反搏压力 增至 0.35kg/cm2以上时 dv/dt 增长转为平緩, 另有 15 例当反搏压力增至 0.4kg/cm2压力才能使 dv/dt持续上升至高峰。 The applicant had admitted 30 patients with coronary heart disease who were voluntarily tested under different counterpulsation pressures. The diastolic phase-incremental wave (hereinafter referred to as DA wave) was calculated and the dv/dt slope was calculated. The counterpulsation pressure increased, and the dv/dt of their DA wave increased gradually (see Figure 4). Among them, 14 cases showed that the dv/dt growth was flat when the counterpulsation pressure increased to 0.35kg/cm 2 or more, and another 15 cases were The counterpulsation pressure is increased to 0.4 kg/cm 2 to maintain the dv/dt to a peak.
此结果说明, 若以提高血流切应力为治疗的目标, 反搏所需压力, 约半 数病人不需要 0.4kg/cm2。 同样, 申请人也曾经针对充气时限、 排气时限、 充 确认本
气时间以及排气时间等参数做过相应的研究, 发现仅仅根据操作者的经验对 一系列的参数进行调整是不科学的, 不能很好地提高血流速度和剪切应力, 达不到理想的反搏效果。 因此对每一个病人进行检测, 确定一组特定的反搏 参数是十分必要的。 This result indicates that if the blood flow shear stress is increased as the target of treatment, the pressure required for the counterpulsation, about half of the patients do not need 0.4kg/cm 2 . Similarly, the applicant has also confirmed the charge time limit, exhaust time limit, and charge. The parameters such as gas time and exhaust time have been studied accordingly. It is unscientific to adjust a series of parameters based on the operator's experience. It is not scientific enough to improve blood flow velocity and shear stress. Counter-effect. Therefore, it is necessary to test each patient to determine a specific set of counterpulsation parameters.
可见, 现有反搏装置, 因反搏参数由操作者设定, 带有主观判断因素, 是否为该病人最佳反搏状态, 没有现实的客观指标, 只能判断该主观设置的 参数是有效的反搏状态, 而不一定是最佳反搏状态。 因为病人个体的差异, 不同的病人的反搏参数的最佳状态会有差别, 只有通过血流速度的检测, 才 能最终确定最佳反搏参数。 It can be seen that the existing counterpulsation device, because the counterpulsation parameter is set by the operator, has subjective judgment factors, whether it is the best counterpulsation state of the patient, and there is no realistic objective index, and can only judge that the subjectively set parameter is valid. The counterpulsation state, not necessarily the best counterpulsation state. Because of the individual patient differences, the optimal state of the counterpulsation parameters of different patients will be different. Only by detecting the blood flow velocity, the optimal counterpulsation parameters can be finally determined.

The Doppler non-invasive blood flow detecting device or the volumetric pulse wave detecting device is directly electrically connected to the counterpulsing device host 1, respectively.
请参阅图 2, 所述多,普勒无创血流检测装置为公知技术, 其采用多普勒 血流测量方法, 能准确又无创地检测反搏过程中血流速度。其工作原理如下: 其由脉冲超声波发射源 71、 脉冲延迟定标系统 72、 接收器 73和方向及流速 后处理器 74等组成。其中脉冲延迟定标系统 72是为了调整接收的开启时间, 让距离为 d的血管 70内血流信号能清晰地被接收。 血管 70内血流方向与接 收信号的极性相关; 当设定 d后, 根据接收到的回波信号经方向及流速后处 理器 74进行后处理即可获得该处血流方向及大小。 Referring to Fig. 2, the multi-Puller non-invasive blood flow detecting device is a well-known technique, which adopts a Doppler blood flow measuring method, and can accurately and non-invasively detect blood flow velocity during counterpulsation. The working principle is as follows: It is composed of a pulse ultrasonic wave source 71, a pulse delay calibration system 72, a receiver 73, and a direction and flow rate post-processor 74. The pulse delay calibration system 72 is for adjusting the opening time of the reception so that the blood flow signal in the blood vessel 70 of the distance d can be clearly received. The direction of blood flow in the blood vessel 70 is related to the polarity of the received signal; when d is set, the direction and magnitude of the blood flow can be obtained by post-processing according to the received echo signal through the direction and flow rate after the processor 74 performs post-processing.
请参阅图 3 , 指容积脉搏波检测装置也为公知技术, 其为光电式传感器。 当光源 77,的波长与光敏元件 78,的特性相匹配, 同时又是在组织中穿透性较 好的近红外单色光时, 它比在血流中的穿透性要强几十倍, 利用此现象制成 指容积脉搏波检测装置。 使用时, 将其光源 77,及光敏元件 78,分别置于被测 指尖两侧。 此时光敏元件 78,接受的光强变化就是脉搏波动时组织中血流透
光率的变化,也就是组织中血流容积的变化。容积流量与流速存在线性关系, 因此容积检测能间接实现血流速度的检测。 Referring to FIG. 3, the volumetric pulse wave detecting device is also a well-known technique, which is a photoelectric sensor. When the wavelength of the light source 77 matches the characteristics of the photosensitive member 78, and at the same time it is a near-infrared monochromatic light having better penetration in the tissue, it is ten times stronger than the penetration in the blood flow. This phenomenon is used to produce a finger volume pulse wave detecting device. In use, the light source 77 and the photosensitive element 78 are respectively placed on both sides of the fingertip to be tested. At this time, the photosensitive member 78 receives a change in light intensity, which is blood flow in the tissue when the pulse fluctuates. The change in light rate, which is the change in blood flow volume in the tissue. There is a linear relationship between volumetric flow rate and flow rate, so volumetric detection can indirectly detect blood flow velocity.

Features.
所述控制模块完成如下操作步骤: The control module completes the following steps:
步驟 1 : 以合理数值初始化各反搏参数; Step 1: Initialize each counter-attack parameter with a reasonable value;
步骤 2: 驱动血流速度检测装置检测并反馈人体的血流速度至本控制模. 块; Step 2: driving the blood flow velocity detecting device to detect and feed back the blood flow velocity of the human body to the control mode.
步骤 3: 基于所测得的血流速度进一步确定最佳反搏参数。 Step 3: Further determine the optimal counterpulsation parameters based on the measured blood flow velocity.
所述最佳反搏参数包括充气时限、 排气时限、 充气时间、 排气时间以及 反搏压力。 The optimal counterpulsation parameters include an inflation time limit, an exhaust time limit, an inflation time, an exhaust time, and a counterpulsation pressure.
在步骤 3中还包括如下步骤: In step 3, the following steps are also included:
步骤 3.1 : 如图 5a所示, 先从心室电兴奋后复极形成的 T波段顶峰向前 移动 10亳秒位置, 且每隔 10毫秒一次, 连续 3次, 计算 D波是否上升, 如 果有, 找出最高值并赋值给中间变量 A, 同时记录下此时的时间, 如果前移 过程中发现 D波值下降, 即可停止前移, 然后再从 T波顶峰向后移动, 看 D 波有无大于 A值, 如有则赋值给 A, 如小于 A值则停止后移。 此时 最后获 得的 A值对应的时间即被确定为最佳充气时间; Step 3.1: As shown in Figure 5a, first move the T-band peak formed by the repolarization of the ventricular electrical excitation to the position of 10 sec seconds forward, and every 10 milliseconds, for 3 consecutive times, calculate whether the D wave rises, if any, Find the highest value and assign it to the intermediate variable A, and record the time at this time. If the D wave value drops during the advancement process, you can stop the forward movement and then move backward from the T wave peak. No greater than A value, if any, assigned to A, if less than A, stop moving backward. The time corresponding to the finally obtained A value is determined as the optimal inflation time;
步骤 3.2: 如图 5b所示, 先从心房兴奋引起的 P波顶峰向前移动, 每 10 毫秒移动一次以录取 3个波并取其均值,计算 S波即收缩波是否下降,如有, 找出其下降至最低者。 如前移过程中见收缩波不降反升, 即可停止前移改为 后移。 直到找到收缩波能下降至最低者为最佳排气时间, 或者也可以继续将 P波前后移动, 求出 D波面积与 S波面积总和最大的为最佳排气时间; Step 3.2: As shown in Figure 5b, first move forward from the peak of the P wave caused by atrial excitation, move every 10 milliseconds to take 3 waves and take the mean value, and calculate whether the S wave is the shrinking wave. If so, find Out of it to the lowest. If the shrinkage wave does not fall back and rise during the forward movement, the forward movement can be stopped and the backward movement can be stopped. Until it is found that the contraction wave energy drops to the lowest, the best exhaust time, or can continue to move the P wave back and forth, and find the maximum sum of the D wave area and the S wave area is the optimal exhaust time;
步骤 3.3 : 如图 5d所示, 从 80亳秒起, 充气时限计算单元每隔一定时 间如 20毫秒测量一次心脏收缩期出现的搏动所形成的 S波和心脏舒张期下 半身加压所形成的反搏 D波,计算 S波和 D波所形成的面积, 至 400毫秒为 止,连续测量三次,取其中 S波加 D波面积比最大时的时限为最佳充气时限;

The D wave is calculated, and the area formed by the S wave and the D wave is calculated. Up to 400 milliseconds, the measurement is performed three times in succession, and the time limit in which the area ratio of the S wave plus the D wave is the largest is the optimal inflation time limit; Step 3.4: As shown in Fig. 5e, the internal pressure of the thigh is detected every 20 milliseconds from 120 milliseconds, and the optimal exhaust time is determined when the internal pressure drops to 1-2 mmHg;
步骤 3.5: 如图 5c所示, 最佳反搏压力的确定首先是利用血流速度检测 装置检测不同反搏压力下患者舒张期反搏波上升支陡度 dv/dt,并记录下不同 反搏压力下测得的 dv/dt值, 所述不同 dv/dt值在平面坐标上所表现出来的曲 线大致呈线性升高后出现一拐点, 采用该拐点作为最佳反搏压力。 Step 3.5: As shown in Fig. 5c, the optimal counterpulsation pressure is firstly determined by using the blood flow velocity detecting device to detect the diastolic counterpulsation rising steepness dv/dt of the patient under different counterpulsation pressures, and recording different counterpulsations. The dv/dt value measured under pressure, the curve of the different dv/dt values on the plane coordinate increases linearly and then an inflection point occurs, and the inflection point is used as the optimal counterpulsation pressure.
下面进一步说明确定最佳反搏压力的具体过程: The specific process for determining the optimal counterpulsation pressure is further explained below:
a、 由控制模块自动设定一初始反搏压力, 如 0.02Mpa, 压力稳定后控制 模块通过接收到的由血流速度检测装置测得的信号, 计算出舒张波的上升支 陡度 dv/dt, 也即上升斜率, 连续将十个斜率值平均后存储; a. The initial counter-pulsation pressure is automatically set by the control module, such as 0.02 MPa. After the pressure is stabilized, the control module calculates the rising branch steepness dv/dt of the diastolic wave by the received signal measured by the blood flow velocity detecting device. , that is, the rising slope, and the ten slope values are successively averaged and stored;
b、 程序自动调整压力, 将其分别升至 0.025MPa、 0.03Mpa、 0.035Mpa、 0.04Mpa、 0.045Mpa等, 并按 a中所述处理。 b. The program automatically adjusts the pressure and raises it to 0.025MPa, 0.03Mpa, 0.035Mpa, 0.04Mpa, 0.045Mpa, etc., and processes it as described in a.
c、 控制模块将 a、 b中所得的各 dv/dt值表现在平面坐标上, 形成趋势图 (参见图 4)。 c. The control module expresses the dv/dt values obtained in a and b on the plane coordinates to form a trend graph (see Figure 4).
d、 所述趋势图的曲线具有一上升段, 而在上其线性升高后出现一拐点, 然后又进入緩慢阶段, 本发明釆用该拐点作为最佳反搏压力。 d. The curve of the trend graph has an ascending segment, and an inflection point occurs after its linear rise, and then enters a slow phase, which is used by the present invention as the optimal counterpulsation pressure.
e、 以 d测得的最佳反搏压力为准, 对患者进行治疗。 e. The patient is treated according to the best counterpulsation pressure measured by d.
此外, 上述步骤 3中, 各个反搏参数之间的确定应保持如下顺序: 首先 保持初始化的反搏压力大小不变, 然后确定最佳充气时间、 最佳排气时间、 最佳充气时限以及最佳排气时限; 其次在充气时间、 排气时间、 充气时限以 及排气时限的最佳值已经确定的情况下, 进一步确定最佳反搏压力。 In addition, in the above step 3, the determination between the respective counterpulsation parameters should be kept as follows: First, the initial counterpulsation pressure is kept constant, and then the optimal inflation time, the optimal exhaust time, the optimal inflation time limit, and the most Good exhaust time limit; secondly, the optimal counter-pressure is further determined in the case where the optimal values of the inflation time, the exhaust time, the inflation time limit, and the exhaust time limit have been determined.
