摘要： A pulse oximeter sensor that is designed to surround an appendage of the patient, such as a finger, toe or foot is disclosed. The sensor has a reusable member which preferably includes a photodetector. A disposable, flexible member preferably contains the photoemitter and can be wrapped around the patient's appendage to secure it to the appendage and the reusable member. When secured, the photoemitter and photodetector end up on opposite sides of the appendage. The disposable member connects to the reusable member to establish electrical contact. The reusable member is connected to a cable which can be plugged into a sensor monitoring system.

摘要： A presenting part fetal pulse oximeter sensor which does not penetrate the fetus' skin, and does not rely on a vacuum for attachment is provided. The fetal sensor of the present invention is held in place by pressure applied to the fetus by a number of different mechanisms. In one embodiment, the sensor is held in place against the fetus by a rigid rod, with the pressure being applied by the physician or technician's hand on the rod. This type of a sensor is useful for spot-checking, where continuous monitoring is not needed. In another embodiment, a pre-loaded spring is coupled between the rod and the sensor head to prevent too much pressure being applied by the user.

摘要： An improved fetal pulse oximeter sensor. The friction provided on the sensor head surface to engage the fetus is higher than the friction on the back side of the sensor head. Thus, any contact with a maternal surface by the back side of the sensor head is less likely to dislodge the sensor, since the maternal tissues will slide over the sensor head. The portion of the sensor surface in contact with the fetus' head will not move because of the increased friction. The increased friction can be achieved by using two different materials with different coefficients of friction, or by using a smooth surface on the back of the sensor head, and a rough surface on the sensor face.
摘要翻译： 改进的胎儿脉搏血氧计传感器。 提供在传感器头部表面上以接合胎儿的摩擦比传感器头部背侧的摩擦力高。 因此，由于母体组织将在传感器头部上滑动，所以与传感器头的背面与母体表面的任何接触不太可能移动传感器。 传感器表面与胎儿头部接触的部分不会因为摩擦增加而移动。 通过使用具有不同摩擦系数的两种不同的材料，或者通过在传感器头部的背面使用光滑表面，以及传感器表面上的粗糙表面，可以实现增加的摩擦。
