WIRELESS, DISPOSABLE, EXTENDED USE PULSE OXIMETER APPARATUS AND METHODS
First Claim
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.

Abstract
Apparatus and methods provide wireless, disposable, continuous pulse oximeter sensor technology, useful and beneficial for a number of applications including relatively extended periods of data collection, and/or packaged in compact and easy-to-use assemblies. Economic fabrication and use provides flexible methodologies that can reduce the overall costs of monitoring and collecting patient'"'"'s physiological data, and provide relatively greater ease and comfort to the patient. A disposable wireless continuous pulse oximeter sensor has a reduced emitter-detector separation, a low-power frontend, and a low-cost processor that sends waveforms to a host device so that the host can calculate and display the parameters of interest. Complications created by the reduced distance between emitter and detector are minimized by using an emitter-detector assembly with an optically dark background, and a bandage for improved optical compliance.
