Abstract

本发明涉及一种医疗器械，特别是涉及一种环式导电液刷。它由压力盘、活塞、橡胶片、锥形杯、环形腔、出液孔、棉垫和套筒构成。活塞杆部的上端是与活塞为一整体的圆盘形的压力盘，活塞的下端处于圆筒形的套筒中，活塞的底部粘接有圆形的橡胶片。套筒的下端是与套筒为一整体的锥形杯。锥形杯是双层圆台形的复合体，两圆台形壁之间是锥形的环形腔，所述环形腔与套筒的内部相通。出液孔的底部粘有圆环形的棉垫。本发明采用了环形活塞的推压，确保有足够的压力使电极液流出，同时达到了均匀涂抹的效果。

Description

环式导电液刷
技术领域
本发明涉及一种医疗器械，特别是涉及一种环式导电液刷。
背景技术
专利号为200820025684.0的发明“导电液自涂式心电图胸导联电极”公开了一种将导电液储存管中的液体通过环形涂液管来实施导电液涂抹的方案，此方案存在以下缺陷：
1.由于导电液储存管的一端开口而另一端封闭，空气难以进入管内，在没有其它压力施加的情况下，导电液难以在其重力作用下流出。
2.由于导电液流入导管的下端与环形涂液管的圆周上某一点相通，这就使导电液在完全充满环形涂液管之前，无法以相同的流速从环形涂液管圆周上的多个孔中流出，这样就难以达到均匀涂抹的目的。
发明内容
本发明为解决现有技术的不足，提供一种能够在人为施加的压力下将导电液均匀分布于电极连接处的环式导电液刷。
解决本发明技术问题的方案是：环式导电液刷由压力盘、活塞、橡胶片、锥形杯、环形腔、出液孔、棉垫和套筒构成。活塞杆部的上端是与活塞为一整体的圆盘形的压力盘，活塞的下端处于圆筒形的套筒中并与套筒成动配合关系，活塞的底部粘接有圆形的橡胶片。套筒的下端是与套筒为一整体的锥形杯。锥形杯是双层圆台形的复合体，两圆台形壁之间是锥形的环形腔，所述环形腔与套筒的内部相通。环形腔的底部有沿圆周均匀分布的出液孔。出液孔的底部粘有圆环形的棉垫。所述环形腔中装有导电液体，使用时，用拇指将压力盘向下压，环形腔内的导电液在压力作用下从环形腔底部的出液孔流入棉垫中，并均匀分布于棉垫的下表面。
采用上述方案，能达到以下效果：
1.由于本发明有活塞施压，确保有足够的压力使电极液流出。
2.由于电极液均匀分布于环形腔中，在推压过程中，每个出液孔的液体压强相等，这就保证了电极液以相同的速度从每个孔中流出并均匀分布于棉垫的底部，这样就达到了良好的均涂效果。

具体实施方式
下面结合附图和实施例对本发明作进一步的描述。
环式导电液刷由压力盘1、活塞2、橡胶片3、锥形杯4、环形腔5、出液孔6、棉垫7和套筒8构成。活塞2杆部的上端是与活塞2为一整体的圆盘形的压力盘1，活塞2的下端处于圆筒形的套筒8中并与套筒8成动配合关系，活塞2的底部粘接有圆形的橡胶片3。套筒8的下端是与套筒8为一整体的锥形杯4。锥形杯4是双层圆台形的复合体，两圆台形壁之间是锥形的环形腔5，所述环形腔5与套筒8的内部相通。环形腔5的底部有沿圆周均匀分布的出液孔6。出液孔6的底部粘有圆环形的棉垫7。所述环形腔5中装有导电液体，使用时，用拇指将压力盘1向下压，环形腔5内的导电液在压力作用下从环形腔5底部的出液孔6流入棉垫7中，并均匀分布于棉垫7的下表面。
