Abstract:
1. A disposable sensor cartridge system comprising: a clip-type noninvasive physiological sensor configured to be placed on a finger of a patient and obtain measurements of physiological parameters of the patient, the clip-type noninvasive physiological sensor including: a disposable sensor cartridge configured to be mateable with the clip-type noninvasive physiological sensor by insertion into the space of the clip-type noninvasive physiological sensor capable of receiving the finger of the patient, the disposable sensor cartridge mateable with the clip-type noninvasive physiological sensor in a single orientation, the disposable sensor cartridge including: wherein the first portion is in contact with the a first region of the finger of the patient while the cartridge is in contact with the finger and the second portion is in contact with a second region of the finger while the cartridge is in contact with the finger, wherein the single orientation is configured to align the emitter with one of the first or second apertures, and align the detector with one other of the first or second apertures, wherein the first and second apertures are configured to allow light emitted from the emitter of the clip-type noninvasive physiological sensor to travel through a path defined by the first and second apertures such that the light is incident on one of the first or second regions of the finger, travels through and is attenuated by the tissue of the finger, exits the finger at the other of the first or second regions of the finger, and is received by the detector of the clip-type noninvasive physiological sensor.
