Abstract
Abstract The universal pulse oximeter probe [of the present invention] utilizes an inexpensive sensor connector configuration to enable the cable section of the probe to be used numerous times. The [sensor connector is mechanically simple and electrically reliable to interconnect the sensor elements with the cable that connects the pulse oximeter system to the sensor elements. This sensor connector enables the user to obtain significant benefits due to the fact that the expensive cable segment of the probe is a separable element from the housing that contains the sensor elements. In particular, the] cable segment of the probe consists of a connector that is compatible with the pulse oximeter system and which functions to interconnect the pulse oximeter system with a plurality of conductors, the far end of which are terminated in the sensor connector [of the present invention]. The probe housing contains a mating element to this sensor connector, the sensor elements and a means of mechanically affixing the sensor elements to the subject. Thus, the cable end of the probe is reusable numerous times and the disposable part of the probe only consists of the housing with the sensors. Furthermore, the housing containing the sensors is electrically configured to be generic to all pulse oximeter system. In this regard, the active elements and passive elements contained therein are directly connected to the sensor connector without interconnection amongst themselves. Jumper leads are provided within the cable half of the sensor connector to electrically interconnect these elements in a manner that is appropriate for the associated pulse oximeter system.
