That's MY invention.

About 2 years ago I had a blue print for a combo heart rate and pulse oximeter so new parents won't have to do the minute by minute check to their baby, it could also prevent SIDS. I couldn't go through with it because I was a little light in the $$$ department. This is very simple technology.





Want to have doctors wrapped around your finger? MIT mechanical engineers Harry Asada and Phillip Shaltis have developed a “ring sensor” that monitors the wearer’s temperature, heart rate, and blood oxygen level. About the size of a class ring, the device is equipped with two light-emitting diodes that beam pulses of red and near infrared light through the user’s finger. A detector on the opposite side of the ring measures the intensity of the transmitted light. Just how much light passes through depends on the oxygen levels and the volume of the blood in its path. Volume changes over the course of a heartbeat and can indicate small changes in heart rate. The battery-powered ring contains a wireless link that can transmit vital signs to a cell phone or computer, allowing a caregiver to determine remotely whether a patient needs assistance. The ring could be used in emergency rooms to monitor patients waiting for treatment, in homes to watch patients after heart surgery, and even in cars to check drivers’ fatigue levels. The researchers have finished a round of clinical tests and are working with companies to commercialize the device within five years.

Then it's considered prior art. They can't patent it but they can trademark it. But of course they can patent the use of LED infrared doppler for this application.

The infrared LED has been in use for 20 years. It's the only means of non-invasive pulse oximetry.

The thing they have is the wireless transmitter that was my hang up otherwise its the same.

I'm going to call the bloodsucker monday and see if we can do anything.
