3. Bring THERMOWAND as a commercial product to market.
What's the Big Deal about Distance?
What is the benefit of taking a temperature of someone from 3 or more feet away? There are already infrared thermometers that work from 6 inches away as does THERMOWAND. The reason distance is critical is it establishes a buffer zone for the exhaled breath of a patient. According to a 2005 article in Infection Control Today, Dr. William Schaffner said, "In droplet spread, infectious agents are spread from the respiratory tract and usually spread only within three feet of an individual...and the more time you spend in that zone, the more likely transmission is to occur." THERMOWAND allows caregivers the option to take a patient's temperature from outside of 3 feet.
THERMOWAND currently takes accurate surface temperature readings from 3 feet with an accuracy of +/- 0.1 degrees Centigrade. The FDA requires infrared sensors accuracy to be +/- 0.2 degrees Centigrade. THERMOWAND accuracy at 3 feet is twice as accurate as FDA requirements.
Getting the right temperature at a distance requires not just the reading from the device of the body surface temperature but knowledge of your BMI, body mass index. That’s why we have a link to our data collection website: www.imt.solutions. No personal contact information or profile is required, it's completely anonymous.
Even if you’re hesitant to financially back our project, you can still participate in the science by visiting www.imt.solutions and taking a few minutes to record your temperature and essential body measurements like height, weight, neck, waist, arm and wrist diameters. This is an approved medical survey by New England Independent Review Board, #15-180.
Not everyone has the same normal temperature and your time spent there would be very helpful in achieving our goals. We need a minimum of a few hundred people to anonymously share their stat's.
What have we done so far?
We've successfully completed the first phases of our design. We demonstrated that our prototype can accurately detect an ambient temperature from at least 3 feet away from a heat source. As you can see in the video above, our prototype is on a breadboard with a working sensor. The display shows the temperature out to hundredths of a degree Centigrade because that is how accurately our infrared sensor can read skin surface temperature. The device seen above and below has been tested using a calibrated ambient temperature-generating black box accurately out to 4 feet! Eventually, THERMOWAND will be capable of updating mobile devices and medical records.
Here is photo of the prototype during testing:
"I hope it hits the market soon. In my opinion, a product like this will be an asset in providing higher quality and safer medical care. I think THERMOWAND would be beneficial in all medical settings." (Andrea Mackenzie, RN)
"As a healthcare provider our goal is to take care of our patients as efficiently and effectively as possible. Having the right tools is essential; THERMOWAND is one such tool." (Heather McIlwee RN)

Development requires testing of THERMOWAND over the human temperature range. We will purchase a Wahl Surface Hot Plate model CBB14KC to verify the accuracy performance of the sensor. It costs about $8000. The second part of this phase is to morph the evaluation board into a pre-production electronic package.
Most people recognize the normal temperature as 98.6 degrees Fahrenheit which is not a surface skin temperature. A correction determined by software will correlate the surface skin temperature with the normal oral thermometer reading. All infrared thermometers do this; THERMOWAND can do it from 3 feet with your help. Please visit our Temperature Survey: https://imt.solutions This is an anonymous survey whose results will be used to calibrate THERMOWAND so it can (optionally) display a normal oral thermometer reading.
Phase Two-Industrial Design
Here the pre-production electronic package is fitted with a housing and battery compartment for Phase 3 testing. This is no small task but we expect to have the services of the industrial designer for the original housing design seen at www.infraredmedicaltechnology.com.
All Phase Two tasks should be completed over the 1st quarter of 2016.
Phase Three-Human Testing
This is the most important phase. It involves the design team, doctors/staff, and of course, volunteers. We expect an immense amount of tweaking and input from the Temperature Survey. The key parameter for this phase is the correlation value between software-determined correction value plus the skin surface temperature and the temperature using an oral thermometer. This phase is expected to begin in the spring of 2016.
Risks and challenges
Research is fraught with wrong turns and misconceptions until the careful scientist gets lucky and notices something. Usually something different from what anyone else thought was important. Here is what we are betting on: infrared sensors "see" more as they back off from the object under observation. The sensor outputs the average surface temperature of the area seen of the object. So if we back off to three feet, we're not just seeing your forehead (the best spot for taking an infrared temperature because it has the highest blood density) but most of your face. Your cheeks are good places to take a temperature but because there is more fat and muscle there the temperature is lower.
While there are lower temperatures surrounding the forehead, the good news is everything moves in concert together. If you are running a temperature, your whole body runs a temperature. Think of your body as connected to a vascular network system. If your core temperature goes up, every part of you has a corresponding increase in temperature. Because your body mass index indicates the amount of insulation around your body we can interpolate that information to apply an offset to the temperature the infrared sensor sees. These new sensor are extremely sensitive at the human body temperature range, down to one/hundredth of a degree. Using modern data mining techniques and as many data records from volunteers at www.imt.solutions as we can get, this problem can be solved. We believe the world will be better for bring this device to market.
