Abstract: Aspects of the present disclosure include a sensor emitter including a reflective cavity for re-directing light to a tissue site. By reflecting light towards the tissue site, the amount of light reaching the tissue site is increased. The increased light can improve parameter measurements taken by a non-invasive physiological sensor by producing a stronger and/or cleaner signal. In an embodiment, the reflective cavity is formed on one or more lead frames of the sensor emitter, wherein the lead frames are capable of transmitting electrical signals to emitting elements coupled to the lead frames. Aspects of the present disclosure also include a sensor component configured to protect connection points of wires to conductive leads on the sensor components by inhibiting flex or bending at the connection points. Connection points can protrude along edges of the sensor component. Aspects of the present disclosure also include techniques and processes for producing low-profile sensors.

Abstract: An optical probe, which is particularly suited to for use in measurements on tissue material of a patient. In one embodiment, the probe comprises upper and lower housing elements incorporating a light energy source and corresponding detector. The tissue material of the patient is disposed between the upper and lower housing elements such that the light energy emitted by the source passes through the tissue material to the detector. A plurality of light shields are attached to one or both of the housing elements to reduce the amount of ambient and reflected light reaching the detector. Additionally, various portions of the upper and lower housing elements and shields utilize light absorbent coloration and/or coatings which further mitigate the effects of undesired ambient and reflected light, thereby reducing noise generated within the instrument and increasing its accuracy. In one embodiment, the light shields are made removable from the optical probe, thereby facilitating replacement.

Abstract: A selectively plated low-noise optical sensor for non-invasive physiological monitoring has an LED emitter that emits light at a known wavelength. The light propagates through a body material and an attenuated signal is received by a photodetector, which produces an electrical signal indicative of the intensity of light energy incident on the detector. The electrical signal is conducted through a plurality of traces to a contact end of the sensor. The contact end allows connection to a connector which communicates the electrical signal to a processor. The emitter and detector are connected to the sensor traces at trace connection pads in the component connection areas. The trace connection pads in the contact area and the connection areas are electroplated with a protective metallic layer. The traces are otherwise covered with a solder mask.
