具体实施方式Detailed ways
以下根据附图说明本实用新型的具体实施方式，The specific embodiment of the present utility model is described below according to accompanying drawing,
<实施例一><Example 1>
图1是本实用新型实施例一的生物能心脏起搏器的结构示意图，如图1所示，生物能心脏起搏器10包括发电部200，心律监测部，脉冲发生器15，以及刺激电极16。发电部200包括发电主体11，整流滤波电路12和输出电极14。Fig. 1 is a schematic structural diagram of a bioenergy cardiac pacemaker according to Embodiment 1 of the present utility model. As shown in Fig. 1, a bioenergy cardiac pacemaker 10 includes a power generation unit 200, a heart rhythm monitoring unit, a pulse generator 15, and stimulating electrodes 16. The power generation unit 200 includes a power generation body 11 , a rectification filter circuit 12 and an output electrode 14 .
发电主体11为有弹性的环形结构，能够环绕于主动脉18的周围，发电主体11内部为纳米级压电材料，可利用主动脉的形变产生电能。发电主体11的输出电极14后连接了整流滤波电路12使得发电主体11输出的电能变得稳定。电能存储单元13连接于整流滤波电路之后，用于储存电能，以供脉冲发生器15使用。脉冲发生器15通过两个刺激电极16连接至心脏17。The power generating body 11 is an elastic annular structure, which can surround the aorta 18. The inside of the power generating body 11 is a nanoscale piezoelectric material, which can generate electric energy by utilizing the deformation of the aorta. The output electrode 14 of the power generation main body 11 is connected with a rectification filter circuit 12 so that the electric energy output by the power generation main body 11 becomes stable. The electric energy storage unit 13 is connected behind the rectification and filtering circuit for storing electric energy for use by the pulse generator 15 . The pulse generator 15 is connected to the heart 17 via two stimulating electrodes 16 .
图2是本实用新型实施例的发电主体的示意图。如图2所示，发电主体11的初始状态为开环的形状，在环形结构的两端各具有一个调节端23，当安装在主动脉外壁时需要将两个调节端连接在一起。在发电主体11和调节端23的外表面覆盖有封装层22。发电主体上具有两根输出电极14，用于将发电主体产生的电能输出。Fig. 2 is a schematic diagram of the power generating body of the embodiment of the present invention. As shown in FIG. 2 , the initial state of the power generating body 11 is an open ring shape, and there is an adjustment end 23 at both ends of the ring structure. When installed on the outer wall of the aorta, the two adjustment ends need to be connected together. The outer surfaces of the generating body 11 and the regulating end 23 are covered with an encapsulation layer 22 . The power generating body has two output electrodes 14 for outputting the electric energy generated by the power generating body.
图3是本实用新型实施例的发电主体的内部结构剖面图，如图3所示，发电主体11的内部为多层薄膜结构，包括位于主体中心层的纳米级压电材料111，以及分别位于压电材料两侧的第一电极层112和第二电极层113。封装层22采用具有生物相容性的柔性高分子绝缘材料，覆盖于发电主体11以及输出电极14的表面，并向发电主体11的外侧延伸形成两侧各一个调节端23。Fig. 3 is the sectional view of the internal structure of the power generation main body of the utility model embodiment, as shown in Fig. 3, the interior of the power generation main body 11 is a multi-layer thin film structure, including the nanoscale piezoelectric material 111 located in the central layer of the main body, and the The first electrode layer 112 and the second electrode layer 113 on both sides of the piezoelectric material. The encapsulation layer 22 is made of biocompatible flexible polymer insulating material, covers the surface of the power generation body 11 and the output electrode 14 , and extends to the outside of the power generation body 11 to form an adjustment terminal 23 on each side.
图4是图3中发电主体A区域的局部放大图，如图4所示，位于发电主体11中心层的纳米级压电材料111，为大规模并联设计的纳米线阵列结构，可有效提高输出电压。第一电极层112和第二电极层113采用金或银等导电率高的薄层材料制成，与纳米级压电材料111相连接。Figure 4 is a partial enlarged view of the region A of the power generation body in Figure 3. As shown in Figure 4, the nanoscale piezoelectric material 111 located in the center layer of the power generation body 11 is a nanowire array structure designed for large-scale parallel connection, which can effectively improve the output Voltage. The first electrode layer 112 and the second electrode layer 113 are made of a thin-layer material with high conductivity such as gold or silver, and are connected to the nanoscale piezoelectric material 111 .
在体内植入时，可以通过外科手术的方法将发电主体11植入到主动脉周围并包绕主动脉。再通过调整调节端23使得发电主体11与主动脉的外壁紧密贴合，以采集主动脉形变所产生的能量。When implanted in the body, the power generating body 11 can be implanted around the aorta and surround the aorta by surgical methods. Then, by adjusting the adjusting end 23, the power generating body 11 is closely attached to the outer wall of the aorta, so as to collect the energy generated by the deformation of the aorta.
对主动脉的过度压迫可能会增加心脏的工作负荷，因此可以在发电主体11与主动脉壁之间临时放置压力传感器以测定发电主体11对主动脉的压力，避免其对心脏产生不良的影响。Excessive compression of the aorta may increase the workload of the heart. Therefore, a pressure sensor can be temporarily placed between the power generation body 11 and the aortic wall to measure the pressure of the power generation body 11 on the aorta to avoid adverse effects on the heart.
由于调节端23的内部不含有压电材料层和电极层，因此当使用手术缝线或钛夹将调节端23的两侧闭合时，不会对发电主体11造成损害。Since the inside of the adjustment end 23 does not contain piezoelectric material layers and electrode layers, when the two sides of the adjustment end 23 are closed with surgical sutures or titanium clips, no damage will be caused to the power generation body 11 .
图5是本实用新型实施例中发电主体安装于主动脉上的截面图。以下结合图1和图5来说明生物能心脏起搏器的工作过程。Fig. 5 is a cross-sectional view of the power generation body installed on the aorta in the embodiment of the utility model. The working process of the bioenergy cardiac pacemaker will be described below in conjunction with FIG. 1 and FIG. 5 .
如图1和图5所示，发电主体11环绕于主动脉18。当心脏17收缩时，血流的冲击使主动脉18发生扩张，如图5所示，主动脉壁45会产生一个对发电主体11的压力F，使压电材料层111发生形变，从而在其两端形成电势差并产生电流，电流通过第一电极层112和第二电极层113传导至输出电极14，再通过整流滤波电路18后进入电能存储部42。电能存储单元13为微型可充电电池。电能存储单元13再将电能供应给脉冲发生器15。当心律监测部探测到心动过缓时，脉冲发生器15将产生电脉冲并通过刺激电极16对心脏进行起搏治疗。As shown in FIG. 1 and FIG. 5 , the power generating body 11 surrounds the aorta 18 . When the heart 17 contracts, the impact of the blood flow causes the aorta 18 to expand. As shown in FIG. A potential difference is formed at the two ends and a current is generated, and the current is conducted to the output electrode 14 through the first electrode layer 112 and the second electrode layer 113 , and then enters the electric energy storage unit 42 after passing through the rectifying and filtering circuit 18 . The electric energy storage unit 13 is a micro rechargeable battery. The electric energy storage unit 13 then supplies electric energy to the pulse generator 15 . When the cardiac rhythm monitoring unit detects bradycardia, the pulse generator 15 will generate electrical pulses and perform pacing therapy on the heart through the stimulating electrodes 16 .
图7是本实用新型实施例的电路图。如图7所示，发电主体11与整流滤波电路12相连接，发电主体11产生的电能经过整流滤波电路12后对电能存储单元13进行充电，电能存储单元13可用于为用电器即本实施例中的脉冲发生器进行供电。Fig. 7 is a circuit diagram of the utility model embodiment. As shown in Figure 7, the power generating body 11 is connected to the rectifying and filtering circuit 12, and the electric energy generated by the generating body 11 passes through the rectifying and filtering circuit 12 to charge the electric energy storage unit 13. The pulse generator in is powered.
