 ThermoScreen Infrared Fever
Screening System
Screening Site Example
A ThermoScreen TS
320 system is placed at the entrance of a hospital to screen patients and
visitors upon entering the building as shown in the figure below. When
properly trained, a single ThermoScreen station can effectively screen over
1,000 subjects per hour.
Screening Area Setup
The screening area
is climate controlled, the temperature varies from 20 to 24°C (68 to
75.2°F), and the relative humidity is approximately 70%. The screening area
has diffuse ambient daylight and soft fluorescent lights. At times, outside
air enters the building through the entrance doors but the camera and
screening area are blocked from any draft using curtain barriers.
During setup, the
screening line mat is placed 1.8m (6 feet) away from the camera for subjects
to stand on while being screened. The camera is carefully aimed in order to
screen subjects with height from
81 to 198cm (2 ’8” to 6’ 6”).
Infants and small children can be held by their parents while they are
screened.
Operator Training
A hands-on training
session is conducted for all operators. Operators are trained to operate
the ThermoScreen software. The ThermoScreen User Manual and Quick
Start/Troubleshooting Cards are kept on hand at the screening station for
operator reference. A screening station logbook is used by operators to
record ThermoScreen usage and personnel on duty.
The Screening Process
With the aid of
barricades, subjects are channeled into a single file line when they enter
the building and each subject is screened individually. Subjects are
notified to remove eyeglasses (contact lenses do not need to be removed),
stand still, and to look at the camera. Subjects can be notified verbally
by the operators or by using carefully positioned signs. Screening of each
subject requires approximately three seconds.
The operator
operates the ThermoScreen system, directs subjects into and out of the
screening area, and directs feverish subjects to the nurse station for
further evaluation.
