Description

利用功能性神经刺激的康复治疗装置
技术领域
本发明涉及医疗器械领域，特别涉及一种用于脑卒中瘫痪下肢的辅助康复、运动神经元损伤肌肉的恢复的一款体戴式的利用功能性神经刺激的康复治疗装置。
背景技术
这些年来由于急性脑血管病及外伤性精髓损伤所致的偏瘫患者越来越普遍，这些病症给患者造成了痛苦。近年来，医学界对医治这类病进行的研究及临床应用开辟了新的医学领域，提出“康复工程学”的说法，现有技术的治疗仪器国内外有多种形式，此外还有如针灸、微波经络穴位治疗仪、电子按摩器、助行装具等，但由于这些仪器、设备体积和重量较大，消耗能源量多，而且只是不同程度地起着针灸、局部刺激、按摩作用，对病人已瘫痪的神经、肌肉并不能使其恢复机能，因此均不能付诸实施。
FES功能性电刺激用于步态训练在国外已比较成熟，国内目前应用较少。FES的主要构成部分是基于步态检测的触发机制设计，目前国内外比较成熟的方式是采用惯性传感器触发及脚踏开关触发，或者生物传感触发。
发明内容
本发明的目的是提供一种利用功能性神经刺激的康复治疗装置，通过步态传感器识别能对人体肢体机能并进行功能性电刺激从而帮助肢体实现机能恢复，该装置同样可用于预防和治疗由于持续性运动神经元或脊髓损害而产生足下垂的症状。
利用功能性神经刺激的康复治疗装置，包括功能性电刺激感应模组、惯性传感单元、电刺激产生单元以及主机；上述功能性电刺激感应模组、惯性传感单元、电刺激产生单元均与主机连接。
所述功能性电刺激感应模组、惯性传感单元、电刺激产生单元这三部件与主机之间设有接插件。
所述惯性传感单元、电刺激产生单元这两个部件与主机之间设有接插件。
所述功能性电刺激感应模组直接通过排线与主机相连。
所述惯性传感单元直接通过排线与主机相连。
所述惯性传感单元通过无线连接方式与主机相连。
所述无线连接方式为蓝牙或者Wi-Fi。
所述主机内设置有相互连接的数据处理装置和数据分析装置；数据分析装置分别与功能性电刺激感应模组、惯性传感单元相连，数据处理装置与电刺激产生单元连接。
本发明的有益效果是：采用功能性电刺激感应模组、惯性传感单元探测病人的信号，然后经过主机的处理使电刺激产生单元产生电刺激帮助肢体实现机能恢复同时预防和治疗由于持续性运动神经元或脊髓损害而产生足下垂的症状。另外，惯性传感单元可以内置在主机内或者外置在主机外，根据需要选择，当需要将惯性传感单元移动到主机外使用时，可采用插拔方式或者直接连接方式连接，这样使用较为方便。

具体实施方式
请参考图1，一种利用功能性神经刺激的康复治疗装置，包括功能性电刺激感应模组1、惯性传感单元2、电刺激产生单元3以及主机4；上述功能性电刺激感应模组1、惯性传感单元2、电刺激产生单元3均与主机4连接。主机4内安装有数据处理装置7和数据分析装置8。
请参考图2及图3，功能性电刺激感应模组1形状类似于人体脚垫的形状，当然为了适应人体的需求还可以设计成其它形状，功能性电刺激感应模组1可为多个。该模组在使用中置于足底感应点，用于感应步态时相信号并将采集到的步态时相信号首先经过接插件5然后通过排线6传递给主机4内的数据处理装置7。
请参考图2及图3，惯性传感单元2与主机4内的数据处理装置7相连，包括三轴正交的陀螺仪，倾角仪，陀螺仪实时监测人体在敏感轴方向的角速度信号，倾角仪则实时测量沿敏感轴方向的角位置信号，并输出与角速度信号和角位置信号相对应的原始电压信号。在实际应用中可安装多个惯性传感单元2。惯性传感单元2将采集到的角速度信号、角位置信号、原始电压信号传递给数据处理单元8。惯性传感单元2可以直接安装于主机4内，也可以与主机4分开，安装于单独的安装盒内。为了能让惯性传感单元2更精确的测量人体运动的信号，需要将惯性传感单元2置于测量目标的膝盖处。当使用者夏天使用的话，由于穿着比较少，可以直将内部安装有惯性传感单元2的主机4直接通过绑带等辅助器件固定于膝盖处，进行人体运动信号的测量。当使用者冬天使用的时候，由于穿着比较多，而且由于主机内的数据处理装置以及数据分析装置等电路板的内置使得主机的尺寸比较大，如果将内部安装有惯性传感单元的主机直接通过绑带等辅助器件固定于膝盖处的话，由于主机的体积比较大，会导致使用者在穿衣服的时候很不方便，或者穿好后，由于主机4置于衣物内过度臃肿而导致行动不便。当然，也可以将内部安装有惯性传感单元2的主机4置于衣物的外面，这会导致测量的数据不准确或者存在误差。为了解决冬天使用者穿戴的问题，在本发明中将惯性传感单元2安装成可移动的，即可以在主机内，也可以在主机4外使用。当冬天在主机4外使用的时候，主机4可以通过穿戴的方式如挂扣等方式置于腰间，而用于测量步态实时数据的惯性传感单元2仍设置于膝盖处的安装盒内。此安装盒的尺寸相对于主机尺寸而言大大减小，固定于人体膝盖处，对人体穿衣服的影响很小，而且很方便。当惯性传感单元2安装于主机4外时，可以通过有线及无线两种方式连接，如通过插拔、导线接口等直接连接方式及蓝牙、Wi-Fi等其它无线连接方式与主机相连。
请参考图2及图3，电刺激产生单元3，用于向人体产生电刺激，可以采用与人体相容性很好的电极片。电极片的数量可以根据实际治疗需要而定，本实施例中，采用两个电极片，每个电极片内安装有电信号输出端口由于与患者的刺激部位相接触，这样可向患者输出用于产生电刺激的电信号，进而刺激患者神经系统。电刺激产生单元3通过插接件5及排线6与主机4相连这样传递信号。
数据分析装置8用于对接收到的信号进行分析，经过分析后并经数据处理装置7处理后就发出指令给电刺激产生单元3给人体提供电刺激从而治疗疾病。
