1. Apparatus for gathering continuous medical data from a patient, including:

  • a wireless disposable assembly mountable on a patient;

    said disposable assembly including a continuous pulse oximeter sensor, said sensor having at least one optically dark background cavity in the wavelength range of interest with at least one multi-wavelength light emitter and at least one light detector mounted to said cavity to detect the light from said light emitter reflected from the patient with negligible light-piping effects so as to acquire high signal-to-noise ratio data relating to at least one of the oxygen saturation level of blood, pulse rate, and blood perfusion index of the patient;

    said disposable assembly including an electronic circuit assembly including (a) a processor, (b) a radio with antenna to transmit information collected by the assembly, (c) a frontend circuitry, (d) a power management circuitry, (e) a control circuitry, and (f) a battery to power the operation of said assembly, said circuit assembly configured to calculate from the information collected by the assembly at least one of the oxygen saturation level of blood, pulse rate, and blood perfusion index of the patient, and to transmit same wirelessly;

    said disposable assembly including a single-use turn-ON switch to enable said sensor to start operation.
