Abstract

The invention relates to a system for detecting infectious diseases with symptoms of fever, infectious disease cases and potential infected people by means of RFID labels placed on their clothes and RFID readers positioned at certain locations. RFID tags contain the ID details of the user and measure body temperature in real time. RFID readers read the body temperature data of people around them and transmit this information to a host computer. The host computer receives the ID and temperature data transmitted by an RFID reader, stores RFID reader information and reading time together with this data in a database, reports to relevant units those with out-of-limit temperature data as a potential case and determines from the database those who have been in the same environment with a case.

Description

DETECTION AND MONITORING SYSTEM FOR INFECTIOUS DISEASES WITH
SYMPTOMS OF FEVER
Technical Field of the Invention
The present invention relates to a system for detecting infectious diseases with symptoms of fever, infectious disease cases and potential infected people by means of RFID labels placed on their clothes and RFID readers positioned at certain locations.
Prior Art
In prior art applications, body temperature is typically monitored by thermal cameras or laser temperature measurement devices, often under the supervision of an operator in charge. Thermal camera systems have a limited area of use due to their high costs. While laser temperature measurement devices are low cost, they can be placed only in certain locations (entrance, etc.) with low frequency of measurements (i.e. daily) due to the need for continuous supervision by an operator as is the case with thermal camera systems. In both systems, it is not quite possible to detect a person who has experienced a change in body temperature during the day. More importantly, no data can be produced on persons potentially contacted by the individual experiencing a change in body temperature.
Radio Frequency Identification (RFID) uses radio frequencies to identify and track tags which are attached to objects and contain a microprocessor with data transfer capability. Data and energy transfer is performed without any contact between the microchip and the reader. RFID tags are grouped into two as active and passive tags. Passive RFID tags are powered by electromagnetic waves transmitted by the reader, while active RFID tags are powered by a battery. Another categorization of RFID tags is possible based on the operating frequency. While tags can be operated at HF, VHF and UHF bands, UHF tags are the most common thanks to their low cost. For instance, UHF RFID tags operating at 960 MHZ frequency band are commonly used in the Turkish textile industry. UHF RFID tags with temperature sensors have become available in recent years. These tags are mostly used for tracking cold chain transportation systems. Tags are particularly placed on meat, milk and related products and medications that need to be transported in cold chain, then measurements are made at certain periods during the transport to check if the cold chain is broken at any point. While they are designed to measure the ambient temperature, the temperature of an object in contact with these tags can also be measured after performing the required measurement calibration. Research on body temperature measurement can be viewed from the documents cited in the reference list below.
In one of the articles [1], RFID technology is preferred for real-time measurement of body temperature. RFID tag is inserted to a dog, and reference RFID tags are used to obtain the location information. The RFID chip’s internal integrated temperature sensor is used for both the human body temperature detection and as a measurement device, while using radio frequency communication to broadcast the temperature information. The study aims to detect body temperature and determine the location. The study does not involve attaching RFID tags to wearable textile products or detecting infectious diseases with symptoms of fever, infectious disease cases and potential infectees.
This article [2] relates to an RFID tag design capable of performing temperature measurement at long range with low power thanks to the integration of temperature sensor (TS) and UFIF RFID technology. After performing a systematic analysis of ADC, TDC and FDC properties of the integrated temperature sensor, it is aimed to achieve low power technology with different materials. The study makes no mention of attaching RFID tags to clothes to monitor body temperature and trace infectious diseases.
Another article [3] relates to a RFID UFIF epidermal sensor suitable to be directly attached onto the human skin by means of a bio-compatible PCL membrane. It aims to monitor and control wounds infection after surgery and the evolution of epidemics involving fever rush. Original designs are provided for the antenna layout of the tag and the area of application, while standard components are used in the electronic assembly. Flowever, infectious disease tracing of individuals in any environment is not possible.
In conclusion, the drawbacks explained above and the shortcomings in existing solutions the problems have necessitated improvement in the related technical field. Aims of the Invention
The present invention is inspired by the existing conditions and aims to solve the drawbacks explained above.
The main object of the invention is to detect all types of infectious diseases with symptoms of fever and groups prone to these diseases at an early stage to refer these cases to disease tests and ensure their isolation from others. By this means, it is aimed to protect public health and avoid losses in productivity. The invention is intended to be used in all premises of organizations or public institutions where people are concentrated indoors, and particularly schools and workplaces.
The invention provides for a low-cost solution with the capability of performing a large number of measurements and producing data about people contacted by the person identified with the disease until a certain time before the identification (for contact tracing purposes) without the need for continuous human supervision.
Wearable RFID (Radio Frequency ID) tagged clothes with temperature sensors will be used to realize these objectives. For instance, these clothes need to be worn by individuals (employees, students, etc.) who are required to be regularly present at an organization. Each tag has unique user-defined ID details. RFID readers will be installed at certain locations inside the organization (i.e. most commonly used routes). RFID readers read the temperature information of people passing by and transmit that information to a host computer together with the appropriate ID details. The host computer will store this information and send warning messages to relevant authorities upon detection of persons who experience a change in body temperature at a predetermined level.
In one preferred embodiment of the invention, RFID tags with a wide area of use operating at UFIF frequency in fully passive mode are employed to provide a low-cost system that allows for reading data as often as desired. RFID readers are used to read data as often as desired and minimize human supervision. The desired number of readers are installed at locations as considered necessary. Each data read from the readers is transmitted to a host computer through the established network infrastructure. In order to trace contacts and identify potential cases within the shortest time possible, data received from the readers are stored in the host computer, analyzed and if required, information can be produced on where the person concerned has been in a certain timeframe and whom the person has contacted.
The below drawings and the detailed description set out with reference to the accompanying drawings provide for a clearer understanding of the structural and characteristic properties and all benefits of the present invention; therefore, the evaluation needs to take these drawings and the detailed description into account.
Detailed Description of the Invention
In order to facilitate a better understanding of the present invention, this detailed description demonstrates the preferred embodiments of the invention in a non-limiting manner.
The system according to the invention reads, for detecting all types of infectious diseases with symptoms of fever, the body temperature of people on the move in an environment (schools, workplaces, shopping malls, etc.) while they are passing predetermined locations and evaluates this data. Passive UHF RFID tags with a temperature sensor that are attached to clothes, contain the ID details of the user and measure body temperature in real time are used in the system. These clothes need to be matched with the user before use. That means, each cloth belongs to one person, while a person can have multiple clothes. This enables determining the user whose temperature value is read. When a reading request is sent to these tags, temperature data of the surface of the tags is sent wirelessly to the respective RFID reader together with the ID details. RFID readers installed at desired locations read the RFID tags around them and transmit either wired or wirelessly the received ID and body temperature data to the host computer through a local network. Multiple readers can operate simultaneously. The host computer adds reading time and reader data to the received ID and temperature data and stores the data in a database. Preferably a web-based application software on the host computer analyzes the collected data and sends a warning message/notification to the relevant persons and organizations in case of reading an out-of-limit temperature data. The application software generates a list of contacts at a desired timeframe when the examination result of a potential case identified by the system is positive. The list of contacts is composed of persons who are obtained through the database scan and who have been in the same environment with the patient at the same time. This allows for performing contact tracing in a fast manner that leaves no room for doubt. In one preferred embodiment of the invention, RFID tags are designed to be attached to ergonomically suitable clothes for the purposes of accurately reading body temperature values and ensuring long service life.
