MEDICAS

Droneprovide due to the high global risk of spreanding of infectious diseases (the present risk is coronavirus) has moved resources to propose a face temperature scanning plug & play infrared imaging solution named MEDICAS.

That solution is based on a real-time continuous calibration using black body radiation source to achieve great accuracy and stability, thermal (640×512 px) and RGB camera.

MAIN FEATURES

• high resolution: 640 x 512px
• high sensitivity: 30mK
• high accuracy ±0.3°C via the real-time black body correction and re-calibration (black body is included in the package)
• integrated full HD visual (RGB) camera
• simultaneous recording videos and images (RGB and thermal)
• special narrow calibration temperature range for face temperature measurement
• Software MEDICAS included in the camera with two-level alarm detection including display notification
• real-time hot spot analysis
• visualisation from both cameras at the same time at display (thermal + visual)
• HDMI for easy connectivity to displays and control via standard USB keyboard (as well as bluetooth keyboards)
• 110 VAC / 230 VAC power supply
• exportable unit worldwide without the licence

CONTACTLESS TEMPERATURE MEASURING

The thermal camera MEDICAS allows to measure the temperature of the human skin and is therefore effective when the body temperature increases for instance due to virus infection. The average body temperature on the skin surface of a healthy human is in the range of approximately 35.8°C to 37°C.

If the human temperature (measured on the surface) exceeds 37°C, it may be an overheating of the body or a defensive reaction of the immune system to the infection of the organism (here the surface temperature can rise up to 4°C, ie. to 41°C).

Accuracy: ± 0.3 °C (temperature accuracy according to reference blackbody)

HOW FEVER DETECTION WORKS

If the human temperature (measured on the surface) exceeds 37 °C, it may be an overheating of the body or a defensive reaction of the immune system to the infection of the organism (here the surface temperature can rise up to 4 °C, ie to 41 °C). In view of the above, it is clear that the system is not specific to coronavirus, but will generally help identify people with fever, as a result of each infection (whether relatively harmless or as severe as SARS , MERS, Ebola, bird flu etc.).

Although it is of course not possible for the infrared camera to detect infected in the non-symptomatic phase of the disease, finding people with clinical manifestations of the disease helps reduce the infection pressure in the population.

SCREENING OF INFECTIOUS DISEASES

In conjunction with an increase in skin surface temperature, thermal camera can be used to detect virtually all types of viral (standard flu or for instance wuhan virus, sars) or bacterial diseases (common angina but also for instance EBOLA) in humans (swine flu, SARS, coronavirus, H5N1, bird flue etc.).

The thermal imaging camera can record temperature changes of 30 mK (0.03°C). Determining the temperature change in case of sick person (compared to a reference black body source) of 1°C is a relatively simple matter, even considering all conceivable uncertainties. For automatic detection, the ISOTHERM function can be used, which is set to a alarm temperature.

WHY INFRARED CAMERA MEDICAS

Standard infrared LWIR measurement works on +-2 °C accuracy, which is absolutely not acceptable for this application. MEDICAS is a unique infrared system which is calibrated in real time on a black body which provides outstanding accuracy ±0.3 °C (comparing to the standard value for thermal camera ±2 °C). Thanks to this precision in measurement the fever could be detected by providing double visual alarm on warning temperature (37 °C) and the critical one (above 38 °C). An operator of the system can easily recognize a person with the fever.

The importance of infrared imaging system during two phases of epidemiological Situation

In recent days, life around the world has been greatly limited by quarantine measures and the situation has evolved in such a way that unfortunately these restrictions will last for many months in different forms. But it will prevent the worst. For this to happen, a highly disciplined and sophisticated approach is needed.

ABOUT CORONAVIRUS & REFERENCES

Coronavirus (COVID-19) is a respiratory illness caused by a new virus. Symptoms range from a mild cough to pneumonia. Some people recover easily, others may get very sick very quickly. There is no treatment. There is evidence that it spreads from person to person. Good hygiene can prevent infection. The World Health Organization (WHO) and U.S. Centers for Disease Control and Prevention (CDC) recommend those who suspect that they are carrying the virus wear a surgical face mask and seek medical advice by calling a doctor rather than directly visiting a clinic in person. As any other infection, infection of coronavirus is charakterised by symptoms, incubation period, mortality rate, age, sex, and existing conditions of deaths.
