Workswell MEDICAS

Be the first to write a review

The new Workswell MEDICAS system was developed especially for the COVID-19 pandemic and allows automated thermal real-time screening for increased body temperature. The system simultaneously detects and automatically analyzes people and groups of people passing within a range of up to 12 meters. If persons with increased body temperature are detected, a visual and/or acoustic alarm can be issued.

The MEDICAS system combines a full HD camera with a high-resolution thermal imaging camera, a built-in PC and an awesome analysis software in one compact device. The high accuracy and measurement stability required for detection is achieved with continuous real-time calibration using a supplied blackbody radiation source.

MEDICAS thus represents the ideal solution for the automatic monitoring of e.g. entrance areas in companies, hospitals, medical practices and pharmacies.

Description

Workswell is well known for advanced thermal imaging cameras, which are used, for example, in thermal power plant applications, building monitoring, in industrial production and in many other areas. The systems are developed and produced in the EU.

Due to the widespread of the COVID-19 pandemic, Workswell has developed a plug-and-play solution for an automated real-time thermal screening of persons and groups of persons for increased body temperature. When a person with increased body temperature passing (e.g. due to an infection by the coronavirus SARS-CoV-2) this is detected and visible on the video.

The thermal camera Workswell 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. 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).

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.

Special features

Detect heat

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.

Monitoring range

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 SARS-CoV2) or bacterial diseases (common angina) in humans (swine flu, SARS, coronavirus, H5N1, bird flue etc.).

Resolution and precision

When measuring at relatively small distances of several meters, camera resolution has a significant impact on the accuracy of the temperature reading. The higher the resolution of the thermal camera, the more distant it can be from the measured surface – in this case, human skin – without distorting the measurement data. This occurs at the level of individual pixels. Since the number of thermal camera pixels is restricted (see Note No. 3), each pixel represents a given portion of the scene. The temperatures within this portion are averaged to create the temperature set of the pixel. Thus, the greater the resolution, the smaller the total projected area per pixel, and the more precise the reading will be.

Distance
