技术领域
本申请涉及医疗设备技术领域,特别是涉及一种肿瘤电场治疗用电极阵列检测设备、系统及其方法。
背景技术
肿瘤电场治疗是一种抗有丝分裂的无创治疗方法,随着科技的发展应用领域也不断得到扩大应用。肿瘤电场治疗能够将低强度、中频、交变电场传递至病灶部位,从而破坏肿瘤细胞分裂,抑制肿瘤细胞增殖,干扰肿瘤细胞迁移和侵袭并减少肿瘤DNA修复的能力。
电极阵列是肿瘤电场治疗设备中重要的组成部分。目前,电极阵列常被配置成电极贴片的形态贴敷于受检者肿瘤部位对应的体表,使电极阵列能够更紧密、更持久的用于实施电场治疗。电极阵列包括柔性电路板、多个间隔设置于柔性电路板上的电极单元以及多个设置于柔性电路板上并位于电极单元同一侧的温度传感器。每个电极单元的中间具有贯穿设置的穿孔。多个温度传感器分别选择性地收容于相应的电极单元的穿孔中,即存在部分电极单元的穿孔内未收容温度传感器。电极单元与柔性电路板通过焊接而实现两者之间电性连接。电极单元与柔性电路板之间因焊接形成间隙。电极单元与柔性电路板之间、电极单元的穿孔内 填充有密封胶。密封胶还包覆位于相应电极单元的穿孔内的温度传感器。电极阵列的柔性电路板包括一与导线焊接的焊接部。柔性电路板的焊接部两侧均设有与导线焊接的多个焊点。电极阵列通过与柔性线路板的焊接部焊接的导线将交变电压传输给与柔性线路板的焊接的每个电极单元,进而通过电极单元将交变电压施加于受检者肿瘤部位。同时,电极阵列还通过与柔性线路板的焊接部焊接的导线将直流电压传输给与柔性线路板的焊接的温度传感器,以使温度传感器感测相应位置处的皮肤的温度。电极阵列中的每一片电极单元是否合格对最终的治疗效果具有重大的影响,因此,为了保证治疗效果,需要对电极单元进行检测。
在相关技术中,在电极阵列检测之前,需要在电极阵列的电极单元远离柔性电路板的一侧表面设置金属镀层。检测时,电极阵列的电极单元表面的金属镀层通过检测设备的压合部压靠在检测设备的测试板上。同时,检测设备的测试探针电接触待测电极阵列的焊接部的多个焊点,以传输直流电压至各个温度传感器,还传输交变电压至电极阵列的各个电极单元。温度传感器通过与待测电极阵列的焊接部的多个焊点电接触的相应的测试探针形成电回路,以感测待测电极阵列所处的环境的温度。温度传感器感测环境温度产生的温度信号通过相应的测试探针被检测设备采集。电极阵列的电极单元表面的金属镀层作为导电介质使待测电极阵列的各个电极单元分别与测试板之间耦合,以在待测电极阵列的各个电极单元与测试板之间分别形成交变电场。随后检测设备分别对待测电极阵列的多个电极单元与测试板之间的电压信号进行检测采样。电极单元表面的金属镀层还可以增加电极单元与测试板之间的容抗,放大检测采样的电压信号,以便于判断待测电极阵列的各个电极单元是否合格。检测后,需要去除电极阵列的各个电极单元表面的金属镀层。该种检测方式,检测工序复杂,且效率低。
在相关技术中,另一种检测方式是在待测电极阵列的电极单元表面贴合金属片使待测电极阵列的各个电极单元分别与测试板之间耦合,以在待测电极阵列的各个电极单元与测试板之间分别形成交变电场。另一种检测方式避免了上一种检 测方式繁琐操作,提高了效率。然而,电极单元与柔性电路板之间、电极单元的穿孔内填充的密封胶过多时,密封胶容易由电极单元的穿孔凸出于电极单元的远离柔性电路板的一侧表面。而同一电极阵列的每个电极单元的穿孔处的密封胶凸起的高度各不相同,并且电极阵列的电极单元与金属片为硬性接触,因此在电极阵列的电极单元的表面与金属片表面贴合时,因密封胶凸出于电极单元的表面的高度差异,使得电极阵列的多个电极单元与测试板之间的间距不一致,导致电极阵列的多个电极单元与测试板之间形成的多个交变电场的电场强度不一致,导致测试采样的电压信号的数据不准确。电极阵列的各个电极单元与对应的金属片之间因两者硬性接触产生的间隙存在差异,导致电极阵列的各个电极单元与测试板之间的容抗不一致,导致电压信号放大的情况不一致,容易影响对待测电极阵列的各个电极单元是否合格的判断。另外,由于金属片与电极阵列的电极单元为硬性接触,在检测设备的压合部下压的作用下,由于密封胶凸出于电极单元的表面,导致电极阵列的电极单元不能平整地接触金属片,电极阵列的电极单元受力不均而容易损坏。

肿瘤电场治疗用电极阵列检测设备1000包括:底座100、组设于底座100上的测试板200以及将待测电极阵列700的多个电极单元710分别压靠在测试板200上的移动组件400。测试板200的上表面具有多个呈间隔状设置的柔性导体300。多个柔性导体300分别与待测电极阵列700的相应的电极单元710一一对应。待测电极阵列700的多个电极单元710由移动组件400分别压靠位于测试板200上的相应的柔性导体300上。柔性导体300具有柔性,能够轻微形变。柔性导体300还具有导电性,在至少一个待测电极阵列700的多个电极单元710电连接交变电压的情况下,能够使至少一个待测电极阵列700的多个电极单元710分别与测试板200耦合导通,以在多个电极单元710分别与测试板200之间形成不同的交变电场。底座100上固定设置有至少一组下探针110。每组下探针110穿过测试板200并与测试板200上放置的相应的待测电极阵列700的位于下表面的相应的多个焊点721电接触。移动组件400上固定设置有至少一组上探针420。每组下探针420与测试板200上放置的相应的待测电极阵列700的位于上表面的相应的多个焊点721电接触。肿瘤电场治疗用电极阵列检测设备1000通过底座100上固定设置的至少一组下探针110及移动组件400上固定设置的至少一组上探针420对至少一个待测电极阵列700进行检测。本实施例中,待测电极阵列700有两个。下探针110、上探针420均设有两组。本申请肿瘤电场治疗用电极阵列检测设备1000的测试板200的上表面设有多个柔性导体300,无需进行电镀、以及去除金属镀层的工序,可实现至少一组待测电极阵列700的多个电极单元710与测试板200之间耦合,从而可以简化检测工序,提高检测的效率;还可以借由柔性导体300的柔性避免至少一组待测电极阵列700的多个电极单元710被压坏的风险;同时,还可以使至少一组待测电极阵列700的多个电极单元710与测试板200紧密贴合,确保多个电极单元710与测试板200之间容抗一致,稳定采样; 也可以减小至少一组待测电极阵列700的多个电极单元710与测试板200之间的间距差异,从而减小多个电极单元710分别与测试板200之间形成不同的交变电场的差异,提高电压信号采样的准确性。
底座100为肿瘤电场治疗用电极阵列检测设备1000的主要支撑部件,其大致为盒体结构或框架类结构。底座100可以由强度较高的材料制成,例如铁、铝等金属材料。底座100的具有一水平的上面板191,以方便组设测试板200。
本实施例中,底座100包括本体190以及组设于本体190上的底板120。底板120固定设置在本体190的上面板191上。具体的,底板120上设置有多个第一安装孔124,本体190的上面板191设置有多个与多个第一安装孔124一一对应的第一固定孔125。底板120上的每个第一安装孔124内穿设有一个第一紧固件123。多个第一紧固件123分别穿过位于底板120上相应的第一安装孔124并螺接于位于本体190的上面板191上的相应的第一固定孔125内。第一紧固件123可以为螺钉等。底板120上的第一安装孔124的数量、本体190的上面板191上的第一固定孔125的数量与第一紧固件123的数量一致。本实施例中,底板120上的第一安装孔124的数量、本体190的上面板191上的第一固定孔125的数量与第一紧固件123的数量均为4个。
本实施例中,两组下探针110固定设置在底座100的底板120上,并且两组下探针110均贯穿底座100的底板120和本体190。本体190的上面板191上设有两个与下探针110对应的下探针避让孔111,以便于下探针在下探针避让孔111内上下移动。在其他实施例中,两组下探针110贯穿并直接固定设置在底座100的本体190的上面板191上,因此,底座100可以不设底板120。
测试板200为板状结构,其平整的组设在底座100上。测试板200为用于检测待测电极阵列700的多个电极单元710分别与测试板200之间的多个电压信号的电路板。本实施例中,测试板200上设有多个彼此间隔的并且独立的多个电极阵列测试单元210。测试板200上的多个电极阵列测试单元210分别与至少一个 待测电极阵列700的多个电极单元710中的一个电极单元710一一对应。电极阵列测试单元210的数量与一次检测所需要检测的待测电极阵列700的电极单元710的数量一致。以图1为例,一个待测电极阵列700具有9个电极单元710,若一次检测同时检测两个待测电极阵列700,那么电极阵列测试单元210的数量可以为18个。电极阵列测试单元210的数量可以根据每个待测电极阵列700中的电极单元710的数量、以及牺牲部730中待测电极阵列700的数量进行设置。
如图6所示,多个柔性导体300均设置于测试板200背离底座100的上表面。多个柔性导体300的上表面齐平。柔性导体300为导电硅胶片,由导电硅胶制成的片状结构,厚度可以为0.3-3mm。柔性导体300具有导电能力和柔性。多个柔性导体300分别使至少一个待测电极阵列700的多个电极单元710中相应的一个电极单元710与测试板200的相应的一个电极阵列测试单元210之间耦合连接。
具体的,测试板200背离底座100的上表面设置有多个凹槽250。每个电极阵列测试单元210设于相应的一个凹槽250内。每个柔性导体300设于相应的电极阵列测试单元210上方。柔性导体300部分地位于该凹槽250内,柔性导体300部分地凸出于测试板200的上表面。在测试时,由于柔性导体300的上表面凸出于测试板200的上表面,有利于待测电极阵列700的多个电极单元710与相应的柔性导体300相互抵靠。
柔性导体300的形状可以具有多种设置方式,例如,柔性导体300可以为圆形或者方形等。继续参照图7,优选的,每个柔性导体300的中心设置有与待测电极阵列700的相应的电极单元710的介电元件711中心的穿孔(未图示)相对应的第一通孔310。每个柔性导体300的边缘设置有沿第一通孔310的圆周方向间隔排布的多个凸起320,多个凸起320沿该第一通孔310的径向凸出。
每个柔性导体300的第一通孔310均为圆形通孔,其轴线可以与柔性导体300的轴线重合,即第一通孔310设置在柔性导体300的中心。每个柔性导体300的第一通孔310正对于测电极700的相应的电极单元710的介电元件711中心的穿 孔(未图示),使得待测电极阵列700的多个电极单元710压靠至测试板200上相应的柔性导体300时,其可以收容待测电极阵列700的相应的电极单元710表面凸起的密封胶(未图示),进一步确保待测电极阵列700的各个电极单元710处于同一高度,使待测电极阵列700的各个电极单元710与测试板200的相应的电极阵列测试单元210之间形成电场强度大致一致的交变电场,进一步提高测试结果的准确性。
每个柔性导体300的边缘的多个凸起320可以为弧形凸起或者尖角形凸起。柔性导体300的多个凸起320可以沿着其第一通孔310的圆周方向间隔设置,使得整个柔性导体300可以大致呈花瓣状。柔性导体300的相邻两个凸起320之间的间隔有利于柔性导体300微弱变形。即当测试板200上设置的多个柔性导体300受到移动组件400施加的压力时,多个柔性导体300可以更容易的完全贴合于待测电极阵列700相应的电极单元710上。
本实施例中,测试板200上设置有两个下探针针孔230,以使得两组下探针110可以通过相应的下探针针孔230向上穿设测试板200,以方便下探针110与相应的待测电极阵列700位于下表面的多个焊点721接触。另外,测试板200的上表面还可以设置有两个分别与相应的待测电极阵列700的焊接部720对应的垫块240。优选的,两个垫块240分别设置在下探针针孔230附近。两个垫块240分别垫起相应的待测电极阵列700的焊接部720,以使每个焊接部720可以大致保持水平,进一步使每个焊接部720的多个焊点721与相应一组下探针110及相应一组上探针420的接触可靠性更好。
优选的,测试板200与底座100之间设有一用于固定测试板200的电极耦合板500。即测试板200通过电极耦合板500组设于底座100上。本实施例中,测试板200固定设于电极耦合板500背离底板120的上表面。例如,测试板200也可以通过螺接、卡接、粘接等常见的方式固定于电极耦合板500。电极耦合板500上也设置有两个供相应的一组下探针110穿过的下探针避让孔(未图示)。
电极耦合板500的上表面设置有用于与待测电极阵列700外围的牺牲部730的多个定位孔731一一卡合的多个定位部520。电极耦合板500的多个定位部520还贯穿测试板200。多个定位部520为柱状结构,从而可以方便地卡合至待测电极阵列700外围的牺牲部730的相应的定位孔731中,从而使得测试板200上的每个柔性导体300正对两个待测电极阵列700相应的一个电极单元710设置,提高测试的准确性。
电极耦合板500正对用于将底板120固定于本体190上的多个第一紧固件123处分别设置有第一紧固件避让孔540。电极耦合板500上的多个第一紧固件避让孔540可以用于容纳相应的第一紧固件123的顶部,使得电极耦合板500能够与底板120尽可能地靠近,甚至无缝贴合。
支承测试板200的电极耦合板500上下活动地组设于底座100的底板120上。在移动组件400与测试板200分离时,支承测试板200的电极耦合板500能够与底座100分离以使固定在底座100上的下探针110的顶端移动至不凸出于测试板200的表面,以保护下探针110,避免下探针110在待测电极阵列700放置在测试板200上时被待测电极阵列700损坏。
本实施例中,在底板120与电极耦合板500之间设有多个第一弹性件121,以在移动组件400与测试板200分离时,电极耦合板500被多个第一弹性件121的弹力作用而远离底座100。多个第一弹性件121相同,使多个第一弹性件121具有相同的弹力。具体的,底板120面对电极耦合板500的上表面设置有多个环形凹槽122。多个环形凹槽122的形状相同,多个环形凹槽122的大小相同。每个第一弹性件121的一端分别抵靠于多个环形凹槽122中一个对应的环形凹槽122的底壁(未标号),另一端均抵靠于电极耦合板500的下表面。环形凹槽122可以起到收容第一弹性件121的作用。当第一弹性件121压缩时,其的大部分或全部均可以压缩至环形凹槽122中,从而进一步缩短底板120和电极耦合板500之间的距离,使得两者可以近乎贴合或完全贴合,从而提高待测电极阵列700的 多个电极单元710和相应的柔性导体300压靠的可靠性。每个环形凹槽122均具有与测试板200垂直的侧壁(未标号)。环形凹槽122还可以引导第一弹性件121的伸缩,使第一弹性件121沿着环形凹槽122的侧壁(未标号)沿垂直测试板200垂直方向伸缩。
本实施例中,每个环形凹槽122内均贯穿地设置有一个第二孔140。每个第二孔140内均设穿有一滑杆510。每个滑杆510包括由上到下依次连接的第二段512以及第一段511。每个滑杆510的第二段512背离第一段511的一端与电极耦合板500固定连接。每个滑杆510的第二段512背离第一段511的一端可以设置有螺纹段(未图示),螺纹段(未图示)可以螺接于电极耦合板500。优选的,每个滑杆510的顶部嵌设于电极耦合板500的内部。每个第一弹性件121可以部分地围设于相应的一个滑杆510的第二段512的相应部分的外围。
底座100上设置有多个分别与相应的滑杆510对应的第一孔130。每个滑杆510的第一段511均收容于底板120上设置的相应的第一孔130内,并且可以在相应的第一孔130内上下移动。
以平行于测试板200的平面为横截面,每个滑杆510的第一段511的横截面积均相同,每个滑杆510的第二段512的横截面积均相同,底座100上设置的每个第一孔130的横截面积均相同,底板120上设置的每个第二孔140的横截面积相同。每个滑杆510的第一段511的横截面积均大于其第二段512的横截面积,底座100上设置的每个第一孔130的横截面积均大于底板120上设置的每个第二孔140的横截面积,且每个滑杆510的第一段511的横截面积均大于底板120上设置的每个第二孔140的横截面积。
每个滑杆510的第一段511的长度均相同,每个滑杆510的第二段512的长度均相同。底板120上设置的每个第二孔140的深度相同。每个滑杆510的第二段512的长度均大于底板120上设置的每个第二孔140的长度。当电极耦合板500相对底板120移动时,每个滑杆510的第二段512均能够跟随电极耦合板500在 底板120上设置的相应的第二孔140中往复移动。由于每个滑杆510的第一段511的横截面积均大于底板120上设置的每个第二孔140的横截面积,当每个滑杆510均能够跟随电极耦合板500在多个第一弹性件121的作用下相对底板120向上移动时,每个滑杆510的第一段511不会移动至相应的第二孔140内,从而可以限制电极耦合板500继续向上移动,从而维持底板120和电极耦合板500之间的间距在一个固定范围内。
本实施例中,电极耦合板500还贯穿设置有沿垂直于测试板200的方向延伸的多个第一导杆530。多个第一导杆530分别位于电极耦合板500的四个角落处。多个第一导杆530均远离电极耦合板500上的测试板200。每个第一导杆530均朝面对底座100的方向延伸。底板120上对应电极耦合板500设置的多个第一导杆530的相应位置处分别设置有第一套筒150。电极耦合板500的下表面设置的每个第一导杆530能够在底板120上设置的相应的第一套筒150中上下移动。当电极耦合板500相对底板120移动时,每个第一导杆530可以沿着相应的第一套筒150在垂直于测试板200的方向上移动。第一导杆530和第一套筒150的导向作用,可以使得电极耦合板500的运动更平稳。
每个第一套筒150沿垂直于测试板200方向的长度均可以等于或者大于底板120的厚度。每个第一套筒150的上表面均可以与底板120的上表面齐平,从而不会影响底板120和电极耦合板500之间的相对移动。每个第一套筒150的下端面均可以与底板120的下表面齐平,或者每个第一套筒150的下端伸出于底板120的下表面。本实施例中,每个第一套筒150的长度均大于底板120的厚度。即每个第一套筒150均向下伸出于底板120的下表面。底座100上设置有多个与相应的第一套筒150一一对应第一套筒避让孔151。第一套筒150伸出底板120下表面的部分可以伸入第一套筒避让孔151中。优选的,每个第一导杆530的长度可以大于电极耦合板500、底板120与底座100的上面板191的总厚度。
移动组件400具有用于将待测电极阵列700的多个电极单元710压靠于测试 板200上相应的柔性导体300上的压合部410。压合部410的结构可以有多种。例如,压合部410可以具有一个水平设置的压合表面(未图示),该压合表面(未图示)可以同时将待测电极阵列700的多个电极单元710分别压靠于测试板200上相应的柔性导体300上。移动组件400沿垂直于测试板200的方向移动,能够带动压合部410移动,使压合部410接触待测电极阵列700的相应部位,并能够通过压合部410提供压力将待测电极阵列700的多个电极单元710分别压靠于相应的柔性导体300上。

压合部410可以包括可移动连接于顶板430的多个相同的压杆411。多个压杆411分别与测试板200上的相应的柔性导体300一一对应设置。每个压杆411均穿设顶板430和压板440。压板440上设置有多个第二通孔441。每个压杆411的底部活动地穿设于相应的第二通孔441。第二通孔441的直径可以略大于压杆411的直径,使得压杆411可以在压板440的第二通孔441内相对压板440移动。压板440上的多个第二通孔441可以起到导向作用。多个压杆411的底部分别通过压板440上相应的第二通孔441与待测电极阵列700的相应部位接触,避免压杆411歪斜而使待测电极阵列700的多个电极单元710受力不均匀、影响检测准确性。
具体的,每个压杆411包括沿垂直于测试板200的方向延伸的杆体412以及与杆体412连接的并用于与待测电极阵列700的相应部位接触的头部413。每个 压杆411的杆体412均为杆状结构。每个压杆411的头部413为压杆411的底部,其可以为块状结构,其下表面为平面,以便于将待测电极阵列700的相应的电极单元710压靠至相应的柔性导体300上。每个压杆411的头部413活动地穿设于相应的第二通孔441。
每个压杆411的杆体412包括中间段412a以及分别位于中间段412a两端的第一凸出部412b以及第二凸出部412c。每个压杆411的杆体412从上到下依次包括第一凸出部412b、中间段412a和第二凸出部412c。每个压杆411的第二凸出部412c与其中间段412a由一台阶面412d斜街。每个压杆411的第二凸出部412c均与其头部413连接。例如,每个压杆411的头部413均可以通过螺钉(未标号)连接至其第二凸出部412c中。具体的,每个压杆411的头部413上可以设置有沉头孔(未标号),以使得螺钉(未标号)不会凸出于其下表面,避免其影响其和待测电极阵列700的相应部位的接触。
对应地,顶板430上设置有与多个压杆411一一对应的多个相同的第二套筒431(如图6所示)。每个第二套筒431纵向地固定于顶板430。每个第二套筒431的长度可以大于顶板430的厚度,其顶端向上凸出于顶板430的上表面,其底端向下凸出于顶板430的下表面。
顶板430上设置的每个第二套筒431均具有侧壁431a以及与侧壁431a连接的顶壁431b。每个第二套筒431的顶壁431b上均设置有用于穿设相应压杆411的中间段412a的第三通孔431c。
每个压杆411的第一凸出部412b位于相应的第二套筒431的顶壁431b外,且其横截面积均大于相应的第三通孔431c的横截面积,从而使每个压杆411活动连接于相应的第二套筒431,以防止每个压杆411在重力的作用下脱离相应的第二套筒431。
顶板430与每个压杆411之间均设置有一个第二弹性件460。每个第二弹性件460用于提供使相应的压杆411将待测电极阵列700相应的电极单元710压靠 与相应的柔性导体300的弹力。第二弹性件460也可以为弹性块、弹性套或螺旋弹簧等。本实施例中,每个第二弹性件460均为螺旋弹簧,位于顶板430相应的第二套筒431的侧壁431a与相应的压杆411的中间段412a之间。即每个第二弹性件460位于相应的第二套筒431内,且套设于相应的压杆411的中间段412a外。每个第二弹性件460的两端分别抵靠于相应的第二套筒431的顶壁431b和相应的压杆411的第二凸出部412c凸出于中间段412a的台阶面412d上。每个压杆411的第二凸出部412c的直径可以略小于相应的第二套筒431的侧壁431a的内径,使得每个压杆411的中间段412a和第二凸出部412c均能够在相应的第二套筒431内移动。
每组上探针420设置于移动组件400的顶板430上。本实施例中,顶板430上对应每组上探针420设置一个上探针基座480。每个上探针基座480均固定在顶板430上。每组上探针420穿设并固定于相应的一个上探针基座480。每组上探针420通过相应上探针基座480固定在顶板430上。压板440对应每组上探针420的位置处均设置有上探针避让孔(未图示),以供相应的一组上探针420穿过,进而方便相应的一组上探针420与对应的待测电极阵列700的位于上表面的多个焊点721接触。
压板440上还设置有多个分别正对电极耦合板500上相应的定位部520的定位部避让孔444,从而使得待测电极阵列700的多个电极单元710能够紧密压靠于相应的柔性导体300。
底座100还包括设于其本体190上的支架160。支架160位本体190的后侧,其可以通过螺钉等方式固定于本体190上。支架160由多个立板相连,整体沿垂直于测试板200的方向延伸。

所述绝缘板2112由绝缘材料制成。优选的,所述绝缘板2112为环氧玻璃布层压板。所述绝缘板2112通过密封剂(未图示)粘附在主体部21111远离人体皮肤的一面,能够增强主体部21111的强度,为主体部21111与介电元件2113之间的焊接操作提供平整的焊接平面,提高产品良率。同时,所述绝缘板2112还可以隔离电极片2100远离皮肤一侧空气中的水汽与位于主体部21111与介电元件2113之间的焊锡2115接触,避免水汽侵蚀主体部21111与介电元件2113之间的焊锡2115,影响主体部21111与介电元件2113间的电性连接。
所述绝缘板2112的大小与所述主体部21111的大小相同,以避免绝缘板2112通过密封剂(未图示)粘贴于主体部21111远离人体皮肤一侧时,密封剂(未图示)通过毛细效应爬至所述主体部21111面对人体皮肤一侧,而影响所述介电元件2113与所述主体部21111焊接形成的间隙2116内的密封胶2117的填充,导致密封胶2117内存在空洞,进而避免密封胶2117在高温固化时因为空洞中的水汽与密封胶2117的热膨胀系数差异大而导致水汽迅速膨胀造成爆裂、产生爆米花现象,损坏产品。
所述介电元件2113由高介电常数材料制成,其具有阻碍直流电的导通、允许交流电通过的导电特性,可保证人体安全。优选的,所述介电元件2113为介电陶瓷片。所述介电元件2113呈环状构造,其中间贯穿设有穿孔21131,用于收容温度传感器2114。所述介电元件2113面向主体部21111的一面附有一层环形金属层21132。所述介电元件2113的金属层21132与主体部21111的导电盘21114的导电芯211140之间形成点对面的焊接,无需要求较高的焊接对位精度,焊接更加方便。所述介电元件2113与主体部21111焊接形成的间隙2116内填充有密 封胶2117,以保护介电元件2113与主体部21111之间的焊锡2115,避免介电元件2113受外力影响而导致焊接处断裂,进而导致交变电场无法通过介电元件2113施加于患者肿瘤部位;同时还可以避免空气中的水汽进入间隙2116而侵蚀介电元件2113与主体部21111之间的焊锡2115,进而影响介电元件2113与主体部21111之间的电性连接。所述介电元件2113的金属层21132的内环与介电元件2113的穿孔21131边缘呈间隔状设置,可以避免设于介电元件2113的金属层21132与主体部21111之间的焊锡2115受热熔化时向介电元件2113的穿孔21131方向扩散而导致温度传感器2114短路。所述介电元件2113的金属层21132的外环与介电元件2113的外缘之间也呈间隔状设置,可以避免设于介电元件2113的金属层21132与主体部21111的之间的焊锡2115受热熔化时向主体部21111外侧溢出而导致在电极片2100贴敷至患者肿瘤部位体表时,未经介电元件2113阻碍的直流电通过而作用于患者体表。
所述介电元件2113的外径略小于主体部21111的直径,可在填充密封胶2117时使密封胶2117沿着位于介电元件2113外侧的主体部21111的边缘通过毛细现象向间隙2116内部填充,有利于介电元件2113与主体部21111焊接形成的间隙2116内的密封胶2117的填充。在介电元件2113与主体部21111焊接形成的间隙2116内填充密封胶2117时,间隙2116内的空气可以从介电元件2113的穿孔21131排出,避免间隙2116内填充的密封胶2117产生空洞,提高产品质量。
参考图21所示,所述温度传感器2114设有多个,分别收容于相应的介电元件2113的穿孔21131内。在本实施例中,所述温度传感器2114的数量有8个,分别位于除中间行正中间的电极单元2110之外的其他8个电极单元2110上。所述8个温度传感器2114分别设于对应的电极单元2110的主体部21111的中心处。所述温度传感器2114用于监测覆盖电极阵列2101的介电元件2113面对人体皮肤的一面的粘贴件2105的温度,进一步检测与粘贴件2105相贴附的人体皮肤的温度。温度传感器2114监测到的温度超过人体安全温度上限时,肿瘤电场治疗 系统(未图示)可及时降低或关闭的传输至电极片2100的交变电流,以避免人体低温烫伤。所述温度传感器2114焊接至主体部21111后再用密封胶2117密封,以防止水汽侵蚀温度传感器2114导致温度传感器2114失效。所述温度传感器2114具有一信号端(未图示)与一接地端(未图示)。在其他实施例中,所述温度传感器2114的具体数量可以依据需要设置。

所述绝缘板6112的大小与所述主体部61111的大小相同,以避免绝缘板6112通过密封剂(未图示)粘贴于主体部61111远离人体皮肤一侧时,密封剂(未图示)通过毛细效应爬至所述主体部61111面对人体皮肤一侧,而影响所述介电元件6113与所述主体部61111焊接形成的间隙(未图示)内密封胶(未图示)的填充,导致密封胶(未图示)内存在空洞,进而避免密封胶(未图示)在高温固化时因为空洞中的水汽与密封胶(未图示)的热膨胀系数差异大而导致水汽迅速膨胀造成爆裂、产生爆米花现象,损坏产品。
所述介电元件6113由高介电常数材料制成,其具有阻碍直流电的导通、允许交流电通过的导电特性,可保证人体安全。优选的,所述介电元件6113为介电陶瓷片。所述介电元件6113呈环状构造,其中间贯穿设有穿孔61131,用于收容温度传感器6114。所述介电元件6113面向主体部61111的一面附有一层环形金属层61132。所述介电元件6113的金属层61132与主体部61111的导电盘61115的导电芯611150之间形成点对面的焊接,无需要求较高的焊接对位精度,焊接更加方便。所述介电元件6113与主体部61111焊接形成的间隙(未图示)内填充有密封胶(未图示),以保护介电元件6113与主体部61111之间焊锡(未图示),避免介电元件6113受外力影响而导致焊接处断裂,进而导致交变电场无法通过介电元件6113施加于患者肿瘤部位;同时还可以避免空气中的水汽进入间隙(未图示)而侵蚀介电元件6113与主体部61111之间的焊锡(未图示),影响介电元件6113 与主体部61111之间的电性连接。所述介电元件6113的金属层61132的内环与介电元件6113的穿孔61131边缘呈间隔状设置,可以避免设于介电元件6113的金属层61132与主体部61111的之间的焊锡(未图示)受热熔化时向介电元件6113的穿孔61131方向扩散而导致温度传感器6114短路。所述介电元件6113的金属层61132的外环与介电元件6113的外缘之间也呈间隔状设置,可以避免设于介电元件6113的金属层61132与主体部61111的之间的焊锡(未图示)受热熔化时向主体部61111外侧溢,避免在电极片6100贴敷至患者肿瘤部位体表时,未经介电元件6113阻碍的直流电通过而作用患者体表。
所述介电元件6113的外径略小于主体部61111的直径,可在填充密封胶(未图示)时使密封胶(未图示)沿着位于介电元件6113外侧的主体部61111的边缘通过毛细现象向间隙(未图示)内部填充,有利于介电元件6113与主体部61111焊接形成的间隙(未图示)内的密封胶(未图示)的填充。在介电元件6113与主体部61111焊接形成的间隙(未图示)内填充密封胶(未图示)时,间隙(未图示)内的空气可以从介电元件6113的穿孔61131排出,避免间隙(未图示)内填充的密封胶(未图示)产生空洞,提高产品质量。

半导体制冷器8104是利用半导体的珀尔帖效应制成的。当贴敷电极片810的患者肿瘤部位的体表有大量热量聚集时,含有电极片810的肿瘤电场治疗系统(未图示)通过柔性电路板8102向半导体制冷器8104输入直流电,半导体制冷器8104内部回路电流流向为自冷端陶瓷片8113的正极焊接盘8119A经冷端导热件8114依次流向与冷端陶瓷片8113的正极焊接盘8119A电性导通的冷端金属导体8115、N型半导体8111、热端金属导体8118、P型半导体8112、与P型半导体8112电性导通的冷端金属导体8115、与冷端陶瓷片8113的负极焊接盘8119B电性导通的冷端导热件8114的导电迹线至冷端陶瓷片8113的负极焊接盘8119B。
半导体制冷器8104的P型半导体8112的电子依次经过与P型半导体8112接触的冷端金属导体8115、冷端导热件8114与冷端陶瓷片8113的导电迹线、与N型半导体8111接触的冷端金属导体8115、N型半导体8111、热端金属导体8118至P型半导体8112。在半导体制冷器8104的制冷端8105处,电子从P型半导体8112经冷端陶瓷片8113流至N型半导体8111时电荷从低能级位置移至高能级位置会自外界吸热。在半导体制冷器8104的散热端8106处,电子从N型半导体8111经热端金属导体8118流至P型半导体8112时电荷从高能级位置移至低能级位置会向外散热。也即,在通过柔性电路板8102向半导体制冷器8104输入直流电时,半导体制冷器8104的制冷端8105的温度降低会通过冷端陶瓷片8113主动从柔性电路板8102处吸热,散热端8106的温度升高会通过热端陶瓷片8116与外界空气进行热交换而散热。冷端陶瓷片8113吸收的热量经冷端导热件8114、冷端金属导体8115、N型半导体8111与P型半导体8112、热端金属导体8118、热端传热件8117以及热端陶瓷片8116传递至电极片810外,以避免在长时间、持续地进行肿瘤电场治疗时患者贴敷电极片810的体表皮肤因热量聚集而造成患者体表皮肤低温烫伤,无需通过停止治疗来避免患者体表皮肤低温烫伤,使患者具有较长的肿瘤治疗时间,取得较好的疗效。

比较采用本实施例的半导体制冷器8104的电极片810与采用与半导体制冷器8104具有相同尺寸大小的环氧玻璃布层压板的电极在施加的电场相同、电极贴敷位置相同、治疗时间相同的情况下患者皮肤表面温升速度,结果显示:采用环氧玻璃布层压板的电极的患者皮肤表面温升速度约为0.0223℃/s(温度测试范围为36.5℃至39℃),而采用本实施例的电极片810的患者皮肤表面温升速度约为0.0108℃/s(温度测试范围为36.5℃至39℃);采用半导体制冷器8104的电极的温升速度在实际使用过程中比采用环氧玻璃布层压板的电极降低了约51.5%。
经上述测试验证,本实施例的电极片810通过在柔性电路板8102的主体部81020远离患者体表一侧设置半导体制冷器8104,能在肿瘤治疗系统的控制器通过柔性电路板8102向半导体制冷器8104输入直流电后可使半导体制冷器8104的制冷端8105主动制冷、吸收因长时间、持续地进行肿瘤电场治疗而产生的位于患者体表并经粘贴件8400、介电元件8103传递至柔性电路板8102上的热量,并通过散热端8106传出电极外,以快速将患者肿瘤体表处的热量散热出去,达到降温的目标,同时可以使患者具有相对较长的治疗时间,确保具有较好的治疗效果,无需通过降低施加于柔性电路板8102上的交变电压或降低通过介电元件8103施加于患者肿瘤部位的交变电压来避免患者贴敷电极位置的体表皮肤低温烫伤。
本实施例的背衬8200还可以在与半导体制冷器8104的热端陶瓷片8116对应位置设置开口(未图示),以使半导体制冷器8104的热端陶瓷片8116暴露在空气中,进一步提升散热效果。根据不同适应症对应的不同人体部位的样本量温度测试数据,可选择仅在温度较高的区域内的电极单元8101焊接设置半导体制冷器8104,便于降低电极片810的整体重量。

参考图62与图63所示,本实施例还提供一种采用上述电极片的肿瘤电场治疗系统的温度控制方法,肿瘤电场治疗系统包括电极片810以及与电极片810电性连接的控制器(未图示),电极片810包括背衬8200、其上设有温度传感器8109的柔性电路板8102、分别设于柔性电路板8102相对两侧的介电元件8103与半导体制冷器8104、环绕设于介电元件8103周围的支撑件8300以及覆盖支撑件8300与介电元件8103的粘贴件8400,介电元件8103与温度传感器8109位于柔性电路板8102的同一侧,半导体制冷器8104夹设于柔性电路板8102与背衬8200之间,温度控制方法具体包括如下步骤:
步骤S81、实时监测电极片810的粘贴件8400的温度;
步骤S82、判断监测获得的温度是否超过调控温度;
步骤S83、根据判断结果控制半导体制冷器8104关闭或判断监测获得的温度是否超过安全阈值;
步骤S84、根据步骤S83中是否超过安全阈值的判断结果控制半导体制冷器8104开启或控制肿瘤电场治疗系统关闭。
步骤S81中电极片810的粘贴件8400一侧与患者肿瘤部位体表皮肤粘贴,另一侧与支撑件8300与介电元件8103贴合。
步骤S81中实时监测粘贴件8400的温度具体是通过设于柔性电路板8102上的温度传感器8109进行监测的。通过温度传感器8109检测与患者肿瘤部位贴合的粘贴件8400的温度是用来通过温度传感器8109获取与粘贴件8400贴合对患者肿瘤部位体表的皮肤温度。
步骤S82判断监测获得的温度是否超过调控温度是通过比较监测获得的温度与调控温度的大小获得的。
步骤S83中判断结果包括监测获得的温度低于调控温度与监测获得的温度高于调控温度。
步骤S83的根据判断结果控制半导体制冷器8104关闭或判断监测获得的温度是否超过安全阈值具体包括如下步骤:
步骤S830、当监测获得的温度低于调控温度时控制半导体制冷器8104关闭;
步骤S831、当监测获得的温度高于或等于调控温度时判断监测获得的温度是否超过安全阈值。
步骤S831中判断监测获得温度是否超过安全阈值是通过比较监测获得的温度与安全阈值的大小获得的。安全阈值与调控温度两者之间的差值在4℃以内,避免温度过低造成人体不适。优选地,调控温度为39°,安全阈值为41°。
步骤S84的根据步骤S83中是否超过安全阈值的判断结果包括监测的温度超过或等于安全阈值与监测温度低于安全阈值。
步骤S84的根据步骤S83是否超过安全阈值的判断结果控制半导体制冷器8104开启或控制肿瘤治疗系统关闭具体包括如下步骤:
步骤S840、当监测获得的温度低于安全阈值时,控制半导体制冷器8104开启并重复循环步骤S81至S83;
步骤S841、当监测获得的温度高于或等于安全阈值时,控制肿瘤电场治疗系统关闭。
步骤S84中控制半导体制冷器8104开启具体是通过控制柔性电路板8102向半导体制冷器8104输入直流电来实现的。
步骤S840的控制半导体制冷器8104开启是指通过柔性电路板8102向半导体制冷器8104输入直流电使半导体制冷器8104处于开启状态。
步骤S841的控制肿瘤电场治疗系统关闭是指控制肿瘤电场治疗系统处于关闭状态,具体是通过关闭肿瘤电场治疗系统的供电电源来实现的。
控制半导体制冷器8104处于开启状态是通过向半导体制冷器8104输入直流电来实现的。控制半导体制冷器8104处于关闭状态是通过关闭输入半导体制冷器8104的直流电来实现的。
半导体制冷器8104处于开启状态时可以通过半导体制冷器8104的制冷端8105主动吸收经粘贴件8400、介电元件8103传至电路板8102的患者肿瘤部位体表产生的热量以及在电极片810工作时柔性电路板8102的导电部(未图示)与介电元件8103产生的热量,并通过半导体制冷器8104的散热端8106将热量快速散发出去,从而快速降低电极片810的粘贴件8400的温度,进而降低患者肿瘤部位体表温度,不需要降低施加于电极片810上的交变电流或降低通过柔性电路板8102的导电部(未图示)施加于介电元件8103上的交变电场而达到降低患者肿瘤部位体表温度的目的,可以实现长时间、持续肿瘤电场治疗,提高治疗效果。
在正常情况下,半导体制冷器8104开启后,皮肤表面温度会缓慢下降,但因为一些内在或外在的原因,会存在小概率电场失控情况,为防止电场过大造成的温升过快,在检测的温度超过安全温度上限(例如,41℃)时,肿瘤电场治疗系统的供电电源会关闭。肿瘤电场治疗系统再次工作需要人为操作开启。
如此设置,可通过温度阶梯(39℃、41℃)控制,尽可能地保持肿瘤电场治疗系统开启运行的同时,降低皮肤表面温度,与传统通过直接关闭肿瘤电场治疗系统进行降温的方式相比,该温度控制方法能够有更多的时间实施交变电场治疗,提高治疗效果。
