1. A device comprising;
(a) two or more disposable pulse oximeter sensor modules, each comprising;
(i) a light emitting source, wherein said light emitting source is capable of sequentially emitting a red light with a wavelength of about 660 nm and an infrared light with a wavelength of about 940 nm;(ii) a photodetector spaced apart from said light emitting source and capable of detecting reflected light from said light emitting source;(iii) a substrate adapted to support said light emitting source and said photodetector, said substrate comprising a molded plastic template;(iv) a source-detector connection connecting said light emitting source to said photodetector; and(v) a sensor cover having an integral sensor window, wherein said sensor cover is positioned to retain said light emitting source, said photodetector, and said source-detector connection between said sensor cover and said substrate; and wherein said sensor window is positioned to allow light from said light emitting source to pass through and to be detected by said photodetector; (b) a banding mechanism, wherein said banding mechanism is configured to be worn around the wrist, and wherein the banding mechanism is capable of circumscribing the wrist, said banding mechanism having:
a skin contacting surface, said skin contacting surface capable of maintaining contact with at least 50% of the wrist skin surface; andan integral pocket configured to receive said two or more disposable pulse oximeter sensor modules; (c) a strut enveloped lengthwise within said banding mechanism, wherein the strut is configured such that providing a bending pressure to the banding mechanism results in the coiling of the strut and ligature of the banding mechanism around the wrist; (d) a window area on the skin contacting surface of said banding mechanism, wherein said window area comprises a pliable plastic sheet, and wherein said window area is integrated into said integral pocket and disposed to allow light to enter and exit the inner area of said integral pocket; and (e) a signal processing unit, wherein said signal processing unit is capable of receiving one or more signal from said photodetector and wherein said signal processing unit determines the percent of hemoglobin molecules bound with oxygen molecules by determining the ratio of absorbance between said red light and said infrared light based on said one or more signal from said photodetector. |
