Abstract: A sensor placement and retention mechanism for use with fetal sensor sites beyond the user's reach are disclosed. The preferred embodiment of this invention is a fetal pulse oximetry sensor (2,200) having an active face (4) through which a light source (6) and a light detector (8) operate. The sensor includes a handle (15) that facilitates placement of the active face at a sensor site in a preferred region beyond the transcervical region and beyond the reach of the user. A pair of electrodes (210,212)--one disposed against the fetus' skin (211) and one exposed to the amniotic fluid--are used to confirm that the sensor is firmly in place on the fetus. In an optional sensor retention feature, a self-inflating bladder (40) presses the active face of the sensor against the fetus' skin to optically couple the sensor with the tissue at the sensor site.

Abstract translation: 公开了一种用于超出用户范围的胎儿传感器位置的传感器放置和保持机构。 本发明的优选实施方案是具有活性面的胎儿脉搏血氧饱和度传感器，光源和光检测器通过该活性面进行操作。 传感器包括手柄，其有助于将活动面放置在超过子宫颈区域并超出使用者可触及范围的优选区域中的传感器位置处。 一对电极 - 一个针对胎儿皮肤设置的电极和一个暴露于羊水的电极 - 用于确认传感器牢固地固定在胎儿上。 在可选的传感器保持特征中，自充气囊将传感器的活动面压在胎儿的皮肤上，以将传感器与传感器部位的组织光学耦合。
