TAURI USER GUIDE
The following guidelines are in response to the Enforcement Policy for Telethermogrphic Systems During the Coronavirus Disease 2019 ( COVID-19) Public Health Emergency.
TAURI is used to estimate the temperature at a reference body site during a triage process. TAURI is NOT intended for a medical purpose and is not a medical device, it is NOT intended for us in the diagnosis of disease or other conditions or in the cure, mitigation, treatment or prevention of disease.
Visual Heat Map patterns are only intended for locating the points from which to extract thermal measurement. TAURI has a measurement error of +/- 0.3 degree Celsius and at an appropriate distance of 0.5 to 1 meter.
The current sensor array is 32 x 32, each sensor point measures an independent temperature that reflects to the heat map.
Factors to consider on SETUP
The infrared camera of TAURI should be positioned perpendicular, both horizontally and vertically to the face of the individual being screened .
The individual being screened and the external temperature reference source should be in the correct position and orientation relative to the camera for proper focal distance, depth of field and image capture. There should be a means of ensuring that the individual being screened is in this proper position e.g. a stool, marks on the floor. Consideration should be given to individuals in wheelchairs.
The backdrop behind the individual being screened and where utilized, side screens should be
thermally uniform, non-reflective in the IR spectrum, and not dark in color in the visible spectrum ( closer to white than black).
The operator should be positioned with a clear visual field of the individual being screened and the display TAURI. The operator can need to intervene to correct the individual’s position. The operator should also be positioned in such a way as to divert individuals to the secondary screening area when required.
Factors to consider on Set Up Environment
The area chosen for screening should have a non- reflective background and minimal reflected infrared radiation from the surroundings. Reflective background such as glass panels should be avoided or covered with opaque materials. Unwanted sources of infrared radiation such as sunlight, heaters, electrical sources and strong sunlight ( e.g. incandescent, halogen, quartz tungsten halogen) should be avoided at the screening area, particularly within the field of view of the camera of TAURI.
The environment in which the individual is being screened can affect the skin temperatures. The temperatures measured by TAURI can be influenced when the individual being screened in sweating. Sweating threshold can vary according to a person’s fitness level, environment of residence, length of adaption and the relative humidity. When humidity is controlled, these effects are minimized. To produce consistent and reliable results of the temperature screening process, it is imperative that TAURI be situated in a stable room temperature with a relative humidity range from 10% to 50% These conditions can best be achieved by creating a local, controlled environment.
Factors to consider on design of Facility Protocol
To facilitate an effective screening operation, trained operators are stationed near the TAURI to observe the temperature of the individual being screened. TAURI is intended to use as a reference device to detect elevated temperature. A raised temperature should confirmed by temperature measurement using a clinical thermometer compliant with ISO80601-2056. Any confirmed cases of raised temperature should be handled according to established medical protocols. It is important to recognize areas of bottlenecks and deploy this equipment appropriately.
Factors to consider on Installation
Location: TAURI should be positioned near the entrance of the facility. The secondary screening area should be at a tangent to TAURI area , but removed from the general traffic flow. Screening near the entrance of the facility prevents comingling. The secondary screening area is a care area that should be equipped with a clinical thermometer and accessories that comply with ISO 80601-2-56 and should be staffed by qualified medical personnel.
Adequate source of supply mains: Since TAURI can have a prolonged stabilization period prior to being ready for use, consideration should be given to a means of providing a reliable source of supply mains. Even a short transient loss of supply mains or start up can cause a 30 min to 40 min delay in the availability of use. Such delays can cause a significant disruption in the flow of traffic.
Lighting: The ambient visual light level should be adequate for operator to determine that the individual being screened is properly positioned and free from obstruction. The lighting source should not produce significant IR emissions, as those can interfere with TAURI. If visual imaging is provided, the light level should be adequate for image quality.
Sources: Thermal sources either hot or cold, need to be avoided in the area around TAURI. Sun facing windows, radiant heaters or sources of cold ( cold windows or outside walls) can interfere with TAURI.
The traffic layout should be designed to channel the traffic into a single file prior to entering each TAURI area.
Toilets should not be proximal to TAURI area This is to both inhibit potential cross- infection.
Humidity and Temperature: The area leading to TAURI and the immediate area around TAURI should be maintained at a humidity level below 50% and a room temperature to minimize the effects, of elevated humidity and ambient temperature, which can produce sweating. Significant convective airflow should be avoided in TAURI.
