    Abstract: An oximeter sensor formed with a housing made of a relatively rigid material into which the oximeter electrical components can be mounted is provided. An overmolded material, of lesser rigidity, is injection-molded over the housing to complete the sensor. In one embodiment the housing is made of plastic, such as polypropylene, and the overmolded material is an injection-molded thermal plastic elastomer, such as Santoprene

    Abstract translation: 提供了一种形成有由相对刚性材料制成的壳体的血氧计传感器,其中可安装血氧计电气部件。 具有较小刚性的包覆成型材料被注塑在外壳上以完成传感器。 在一个实施例中,壳体由诸如聚丙烯的塑料制成,并且包覆成型的材料是注射成型的热塑性弹性体,例如Santoprene TM (具有1微米尺寸的橡胶颗粒的聚丙烯)。 壳体优选地包含连接较厚部分的薄壁部分,其支撑电和光学部件。 这些薄部分在最终的血氧计传感器中提供天然弯曲部分。 通过将薄壁部分靠近或在中心处,传感器柔性的中性轴在纵向方向上被优化,而壳体侧向提供刚度。
