Abstract

一种电疗器包括:一个空心圆柱形机壳,其前端部分通过一个卡环装有一个轴向可转动的导电帽,一根引线使导电帽与机壳内的压电元件负极相连,其正极通过导线和终端部件与导电帽的内表面形成一个放电缝,机壳后部的压力施加器可使该压电元件产生高压放电电流,通过旋转卡环可调整放电缝的宽度进而改变施加到穴位上的放电电压并由导电帽实现对穴位的面式放电。

Description

本发明涉及一种电疗器,该电疗器内部具有一个在高压下可产生刺激人体的放电电流的压电元件,可通过输出电极对人体进行刺激。
当汽车驾驶员或参加考试的学生在长时间过度紧张之后变得困时,或者当类似的情况发生时,常常需要通过对人体施加一种舒适的刺激以使大脑得到恢复。人们也知道,通过瞬时向人体皮的某个部位(尤其是向灸灼六位)进行高压电流放电,便可得到与针灸疗法类似的疗效。然而,由常规电刺激器释放的电压均很高,可高达15000伏。因此,对于如此强烈的电刺激,由于个体间的差异,有些人就不愿意使用这种电刺激器,有时使用这种电刺激器还会带来危险。在常规电刺激器的情况下,并未考虑到如何有选择地控制这一电压,并且,也未考虑到如何改变输出电极端部的点式放电以减弱刺激的强度。
本发明的一个目的在于提供一种能够方便而又稳定地对人体施加电刺激的便携式电疗器,该电疗器的输出电压可根据使用者的需要来调节,并且该输出电压可通过输出电极进行面式放电,以此改善它对局部皮肤的刺激。
根据本发明,上述目的可通过采用以下的电疗器而得到以实现,该电疗器包括:一个压电元件;一个将压力施加器推向该压电无件以使其产生高压电流的推动件;一个容纳该压电元件的圆筒机壳,其前端部分内安装了一个套环,该套环的中央部分暴露出从上述压电元件引出的一根寻线,该导线与一个终端部件连接;一个具有一定长度的绝缘长环轴向可移动地装配在上述圆筒机壳的前端部分外侧,此外,一个装在作用部位上的导电帽与上述卡环的前端粘接在一起,使帽的底面与上述终端部件相对,并且,上述卡环可轴向移动,以便调整上述底面与上述终端部件之间的间隔距离。
图1是一个侧面剖视图,显示的是根据本发明的第一实施方案的电疗器。
图2是一个侧面剖视图,显示的是根据本发明的第二实施方案的电疗器。
参见图1,所示为本发明的第一实施方案,在这个方案中,空心的圆柱形机壳11具有一个前端部分,一个轴向转动的导电帽1 3,通过一个卡环20(描述在后)而被可拆装地固定在这个前端部分上,一个终端引线(未示出)使帽13与压电元件14的负极相连。在机壳11的内部,压电元件14被设置成其正极导线16向前延伸到终端部件12内,终端部件12通过一个放电缝与帽13的内表面相对以形成一个放电区,推动压电元件的压力施加器18的推动件19可移动地安装在压力施加器的后部。
采用图1所示的电疗器,当手持机壳11,使帽13与人体相接触,然后推动件19的一头以与压力施加器18的偏压力相反的方向被推动时,压力施加器18向压电器15移动以即刻产生一种高压放电电流,该电流通过导线16,终端部件12,放电缝和帽1 3而流过人体。圆柱形机壳11,导体16的套环17以及帽13的卡环20都是用绝缘材料制成的。
为了得到强烈刺激,通过转动装在套环17上的螺纹卡环20,帽13便被轴向移动,以便能使终端部件12几乎与帽13的下表面相接触,相反,要想得到弱刺激,则应向相反的方向转动套环20,以便终端部件12能以相当的距离与帽13的下表分隔开。
以上实施方案的实质在于:1.导电帽13和终端部件12之间的距离可通过操作卡环20而选择性地扩大(不用说,也可相互接触);2.施加到人体的放电不是来自终端部件12,而是来自与该终端部件12相对的导电帽13的外表面。换句话说,上述特征导致:(a)当通过松动卡环20使导电帽13与终端部件12分离得尽可能远时由于导电帽13和终端部件12之间存在的空气电阻使导电帽表面的放电电压迅速下降并最终达到基本为零。这意味着根椐本发明的电疗器可在0-15000伏的范围内选择性地控制放电电压。因此,本装置可释放适合于使用者本人的电压,这也包括那些对电刺激反应异常敏感的人和反应不良的人,具体分式是,开始时将电压降低,然后通过旋转卡环20使导电帽13连续地接近终端部件来进行控制以获得最高可达15000伏的一个适宜的电压。(b)在本装置中,导电帽13是由导电材料制成并通过其表面进行放电,因此,与人体接触的放电区可成为一个放电面,该放电面可很好的覆盖需要进行刺激的人体灸灼穴位。因而本装置能够无故障地可靠的达到医疗目的。并且,与人体接触区域的扩大与电压大小无关,因而可减小单位面积上的电量(安培)。所以,本装置可以非常安全的应用在需要慎重的部位,如头部等。
参见图2,所示为本发明的第二实施方案,其中,一个空心圆形机壳21具有一个前端部分,一个轴向可移动的永磁帽23可拆装地固定在该前端部分上。帽23是由一个螺纹套环20′支撑,并且大体上在其中心处有一个穿孔22。在机壳21里面,置有一个压电元件24;一根导线26,它向前延伸并且其终端为一针式触点,该触点被容纳在帽23的穿孔22里的放电套筒27所围绕;一个将压力施加器28推向压电元件24的推动件29可移动地固定在压力施加器28的后部。
采用如图2所示的电疗器,当推动件29的一头被以与压力施加器28的偏压力相反的方向推动时(与第一实施方案中一样),压力施加器28被移向放电器25以即刻产生一种高压放电电流。该电流通过在导线26触点处的放电套筒以及通过在帽23与放电套筒27之间形成的放电区而传遍人体。
为了得到强刺激,可将帽23沿螺纹方向拧紧,以使导线26的尖端部分紧紧贴近人体皮肤,而为了得到弱刺激,帽23则沿着螺纹反方向松开,以使导线26的尖端部分与皮肤分开。
在本实施案的电疗器中,由于与皮肤相接触的帽23是永磁的,这样由永磁材料所产生的磁力线可以与通过导体26而产生的电刺激同时施于人体,以加速血液的循环。如果得到的电刺激不理想,这个治疗器还可有效地作为一个磁疗器来使用。
