Ultra Low Power Pulse Oximeter
Pulse Oximeters have been used in clinical settings for more than twenty years to non-invasively measure the amount of oxygen in a patient's blood. The fundamental Oximeter technology is based upon the measurement of the ratio of light absorption of red and infrared light as transmitted through the thin part of a patient's anatomy (e.g. fingertip).
There is a widespread move toward the expanded use of Oximeters in wireless, remote monitoring of patients' vital signs. This patent pending invention enables this use by reducing power requirements by an order of magnitude below the level required in current devices. The technology features a novel photoreceptor with an advanced ultra low power and compact circuit design. It is envisioned that the photoreceptor and circuitry can be retrofitted into existing OEM devices.
A prototype of the device has been built and tested, and it has exhibited the anticipated low power requirements (<5 mW). Further modifications and improvements will achieve a reduction to <1 to 2 mW which are expected to provide even greater advantages and device functionality.
