Abstract:
1. A sensor holder for holding a reflectance type oximetry sensor against a patient's skin, the sensor holder comprising: a base portion having an adhesive bottom surface adapted to temporarily stick the base portion onto the patient's skin, the base portion having a central void therein that is bordered by at least one inner wall; and a roof portion positioned above the central void and attached to the base portion so as to form an interior cavity between the roof portion and the at least one inner wall, wherein the interior cavity is dimensioned to accept the oximetry sensor, wherein the roof portion and the base portion are configured so that when the sensor holder is positioned over the oximetry sensor and stuck on a patient's skin, the oximetry sensor exerts an upward force against the roof portion, and an interaction between the roof portion and the base portion causes the roof portion to exert a downward force on the oximetry sensor, wherein the roof portion and the base portion are configured so that the upward force against the roof portion is directed radially outward, with respect to the central void, from the at least one inner wall, wherein the roof portion and the base portion are connected radially beyond a region that is adjacent to the at least one inner sidewall and extends radially outward from the at least one inner sidewall, and wherein the roof portion and the base portion are not connected within the region.
