Claim Text:
1. An apparatus comprising: a single-body unit configured to calibrate a pulse oximeter that uses probe light beams having pre-determined wavelengths to measure the saturation of peripheral oxygen (SpO one or more polymer materials that form a flexible solid medium configured to transmit a pulsatile rhythmic train of action force received by the single-body unit during calibration of the pulse oximeter; one or more scattering materials to scatter the probe light beams, wherein the scattering of the probe light beams by the one or more scattering materials during the calibration of the use oximeter emulates scattering behavior of the probe light beams when propagated in the pre-determined human body part; and one or more dye materials to attenuate the probe light beams, wherein the attenuation of the probe light beams by the one or more dye materials during the calibration of the pulse oximeter emulates to absorption behavior of the probe light beams when propagated in the pre-determined human body part, wherein the one or more polymer materials form a bulk of the single-body unit, wherein each of the one or more scattering materials and each of the one or more dye materials are substantially-uniformly dispersed in the entire single-body unit, and wherein the one or more polymer materials, the one or more scattering materials, and the one or more dye materials are selected such that the mixture of materials forming the single-body unit emulates a particular SpO
