技术领域technical field
本实用新型属于医疗技术领域，尤其涉及一种电磁式磁敏感应反馈信息的系统。The utility model belongs to the field of medical technology, in particular to an electromagnetic susceptibility feedback information system.
背景技术Background technique
随着微电子技术的发展和医学水平的提高，植入式医疗器械得到越来越广泛的应用，从心脏起搏器、脑深度刺激器、脊髓刺激器到人工细胞和人工器官等。With the development of microelectronics technology and the improvement of medical level, implantable medical devices have been widely used, ranging from cardiac pacemakers, deep brain stimulators, spinal cord stimulators to artificial cells and artificial organs.
对于植入式有源医疗器械的反馈控制：植入式医疗器械的闭环反馈治疗应用，必须要解决反馈信号的获取方式及反馈方式。目前有两种基本的反馈路径实现方式：一、植入式设备自带采样电路和反馈电路(自适应心脏起搏器等多采用这种反馈路径)；二、由体外设备或医生主观诊断获取信息，依靠无线通讯的方式与植入式设备相互传递信息。在植入式神经刺激器领域，由于需要多种生理参数作为判断依据，主要采用第二种反馈路径。For the feedback control of implantable active medical devices: the closed-loop feedback therapy application of implantable medical devices must solve the acquisition method and feedback mode of the feedback signal. At present, there are two basic ways to realize the feedback path: 1. Implantable devices have their own sampling circuit and feedback circuit (adaptive cardiac pacemakers often use this feedback path); 2. Obtained by in vitro equipment or subjective diagnosis by doctors Information, relying on wireless communication to transfer information to and from implanted devices. In the field of implantable neurostimulators, the second feedback path is mainly used due to the need for multiple physiological parameters as the basis for judgment.
无线通讯的实现方式主要是依赖较低频率的电磁感应线圈或较高频率的无线电进行信息传递。现有的体内医疗器械无线通讯电路，需要至少有天线，收发器，调制解调器，基带信号处理器等模块构成，需要较多的元器件，会增加植入式设备的体积和重量；另外，通讯过程中各个模块的电流(通常在几mA至几十mA)会消耗对植入式设备非常宝贵的电能。The realization of wireless communication mainly relies on a lower frequency electromagnetic induction coil or a higher frequency radio for information transmission. The existing wireless communication circuits of medical devices in the body need to be composed of modules such as antennas, transceivers, modems, and baseband signal processors at least, and require more components, which will increase the volume and weight of implanted devices; in addition, the communication process The current of each module in the device (usually a few mA to tens of mA) consumes very precious power for implantable devices.
对于植入体内的有源医疗器械，为了增加设备的可靠性，通常会设有一个磁敏元件，通过较强的磁场变化激活开关，从而实现设备复位，启动/停止，模式转换等功能。For active medical devices implanted in the body, in order to increase the reliability of the device, there is usually a magnetic sensitive element, which activates the switch through a strong magnetic field change, so as to realize functions such as device reset, start/stop, and mode conversion.
目前通常使用一块固定场强的永磁体，通过控制磁体靠近设备的时间长短来实现操作磁敏元件的目的。在实际使用过程中，一方面，如果对时间、距离、位置掌控不好，经常会发生操作失败；另一方面，如果使用者经常接触较强的磁场(例如使用磁化杯，微波炉，靠近冰箱门等)，也会发生磁敏元件误动作引起的异常操作；此外，永磁体在其自身较强的磁场会对周围的物体产生影响，例如银行卡消磁，数码相机的光圈、快门失调，微型电机运转异常等。At present, a permanent magnet with a fixed field strength is usually used, and the purpose of operating the magnetic sensitive element is realized by controlling the length of time that the magnet is close to the device. In actual use, on the one hand, if the time, distance, and location are not well controlled, operation failures often occur; on the other hand, if the user is often exposed to a strong magnetic field (such as using a magnetized cup, microwave oven, etc.), abnormal operation caused by misoperation of magnetic sensitive elements will also occur; in addition, the strong magnetic field of the permanent magnet will affect the surrounding objects, such as bank card degaussing, digital camera aperture, shutter misadjustment, micro motor Abnormal operation, etc.
