Description
技术领域
本发明涉及植入式远程监测定位系统，特别的涉及一种多电池充电的可植入医疗设备的远程监测定位系统。
背景技术
一些突发病的患者或者年纪较大的患者会出现外出时病症发作或发生其他意外事件的可能，如果无法及时获知或采取措施，容易造成严重的后果。
专利EP2043502B1公开了一种植入远程设备，可远程上传患者生理传感数据，方便远程的医生查看，但是需要固定地点进行数据上传，无法在外出时上传数据且无法检测症状发作或其他意外事件。
植入设备可以外传生理数据或检测疾病发作，但是目前无法实时确定位置，其次，在进行定位功耗过大。及时给远程监测定位系统进行电能补充的技术问题成为当前技术难点。
发明内容
本发明的目的在于克服上述技术中的不足，提供一种多电池充电的可植入医疗设备远程监测定位系统，包括可植入医疗设备与远程服务器；可植入医疗设备包括传感器，处理器，唤醒模块，充电线圈，至少一主电池，至少一备用电池，定位模块和远程通信模块；可植入医疗设备的传感器包括加速度传感器，陀螺仪，心电传感器，血氧饱和度传感器；处理器控制充电线圈给至少一主电池和至少一备用电池充电；处理器控制至少一备用电池给至少一主电池充电；传感器采集生理参数，处理器判断生理参数的变化是否达到突发状况阈值，如心率变异度增大到一定阈值，血氧饱和度减小到一定阈值判断癫痫发作，加速度传感器与陀螺仪参数变化达到一定阈值判断摔倒，确定发生突发状况，处理器控制唤醒模块，唤醒定位模块请求当前位置，获得当前位置后定位模块关闭，将位置，参数与突发情况通过远程通信模块上传至远程服务器；远程可使用蜂窝移动通信。
进一步的，还包括医生主机，远程服务器接收到定位数据与突发情况向医生主机预警。
进一步的，还包括体外控制器，体外控制器可选择定位模式，常规模式，关闭模式与周期模式，上述方案为常规模式，关闭模式开启后不进行突发状况检测及定位，周期模式可以不仅仅在突发状况发生时进行定位，可设定周期，周期性地唤醒定位模块请求位置并上传，周期上传数据医生可查看，突发状况发生时医生主机依然进行预警。
该系统能够使得可植入医疗设备耗电较多时，及时快速的补充电能，保证患者安全。
附图说明
图1是本发明的多电池充电的可植入医疗设备远程监测定位系统图。
具体实施方式
下面结合附图和具体实施例，对本发明提供多电池充电的可植入医疗设备的远程监测定位系统及其工作方法作进一步的详细说明。附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
请参见图1，本发明实施例提供一种多电池充电的可植入医疗设备远程监测定位系统，其包括一可植入医疗设备101、一远程服务器102以及一医生主机103。
在本发明的实施例中，所述可植入医疗设备101使用时植入在患者体内。所述可植入医疗设备101可以为心脏起搏器、除颤器、脑深部电刺激器、脊髓刺激器、迷走神经刺激器、胃肠刺激器或者其他类似的植入式医疗器械。本发明仅以心脏植入设备为例进行说明。
在本发明的实施例中，可以包括一体外控制器，其可以与可植入医疗设备101以及医生主机103进行双向通信并输出数据或指令。所述体外控制器通过有线或无线的方式与可植入医疗设备101通信，当可植入医疗设备101发生突发危机状况时，可立即进行定位，并设定周期，以周期性地唤醒定位模块请求位置并上传位置数据，供给医生查看，从而达到将突发状况及时发送给医生主机进行预警的目的。
在本发明的实施例中，如图1所示，所述的可植入医疗设备101包括传感器201、处理器202、唤醒模块203、定位模块204、远程通信模块205、充电线圈，至少一主电池，至少一备用电池。处理器202控制充电线圈给至少一主电池和至少一备用电池充电；处理器202控制至少一备用电池给至少一主电池充电。主电池和备用电池为锂离子充电电池或其他充电电池或快充电池。
在本发明的实施例中，所述的可植入医疗设备101被构造为植入到病人身体的相应病灶部位，因此优选的是，所述的可植入医疗设备101包括由在生物学上为惰性的相对刚性的材料（诸如钛或硅酮）构成的外壳，以心脏植入设备为例，如起搏器，可构造成向病人的心脏提供电刺激，对于本领域技术人员而言，使用电刺激以治疗失调（诸如心动过缓以及心动过速）是公知常识。所述传感器201用于测量在远程监护过程中患者的电生理信号。所述的传感器201种类包括但不限于加速度传感器、陀螺仪（角速度传感器）、心电传感器、血氧饱和度传感器等中的一种或多种。
加速度传感器和陀螺仪是运动监测领域中常见的跌倒监测装置，以Freescale公司的MEMs三轴加速度传感器MMA7260为例，该传感器具有低功耗、高灵敏度、响应时间短的特点，抗震能力强，本实施例优选使用以下参数：量程为正负6g，灵敏度由200mV/g，响应时间1ms。
所述心电传感器具有全面检测心脏运行状况的能力，例如精确区分细胞内及细胞外心肌动力学、患者心脏容积变化、心肌收缩强度，以多种方式对患者的心脏接收到的数据进行分析，创建或生成患者心电图的图形表示，例如从患者的心脏接收到的电信号可以包括利用8位分辨率以1KHz进行数字化的模拟心电图信号，以得到被存储并稍后进行分析的参考波形。通过对心电图QRS波群的分析，得到患者实时的心率、PR间期、RR间期、QRS间期，根据多种测量参数获得的心率变异度评估患者当前的心脏功能，例如窦性心律不齐、窦性心动过速、窦性心动过缓、心房除极至心室除极时间、心室肌除极电位变化、心室肌除极和复极全程时间等。
血氧饱和度是血液中被氧结合的氧合血红蛋白的容量占全部可结合的血红蛋白容量的百分比，即血液中血氧的浓度。血氧保护度过低，直接影响心脏的搏动功能，首先出现的是代偿性心率加速、心搏及心排血量增加，循环系统以高动力状态代偿氧含量不足，并伴有高风险的癫痫症发生。在严重低氧状况时，导致心动过缓、前期收缩、血压下降与心排血量降低，以及出现室颤等心率失常乃至停搏。根据氧合血红蛋白和非氧合血红蛋白对不同波长入射光有着不同的吸收率，当单色光垂直照射动脉血液时，其对光的吸收量将随透光区域动脉血管搏动而变化。当发光器件发射出波长为650nm的红光和波长为940nm的红外光，透过血液区域后，被光敏接收器件（一般为PIN型光敏二极管）接收，并将反射光信号转换为电信号，根据对入射光吸收率的差异，最终获得血氧饱和度信息。
