Description

Technical Field

[0001] The present invention relates to the field of public health close contact screening (i.e., close contact screening) methods and systems, and in particular to a method and system for intelligent collection and matching of close contact information based on an epidemic investigation bracelet. Background Art

[0002] With the acceleration of globalization, the flow of people is becoming more frequent, and the speed and scope of the spread of infectious diseases are constantly expanding, posing severe challenges to global public health security. In the field of public health, it is necessary to be fully prepared for the prevention and control of infectious diseases in order to respond to the outbreak of infectious diseases that may occur at any time, especially for the screening and screening of close contacts, such as people living together in key places such as infectious disease hospitals, cabin hospitals or quarantine hotels, direct caregivers or those who provide diagnosis and treatment, nursing services, medical staff who visit cases, family members or other people who have close contact, medical staff who carry out aerosol diagnosis and treatment activities in the same space, and people who are exposed to the environment and objects contaminated by cases or asymptomatic infections. How to quickly and accurately screen and screen close contacts during the epidemic prevention and control period is crucial to controlling the spread of infectious diseases.

[0003] However, based on past experience, staff usually track the activity trajectories of suspected close contacts of confirmed cases through face-to-face questioning, code scanning records in key places and public places, video surveillance records in key places and public places, etc. This not only consumes a lot of manpower, material resources, financial resources and time, making the efficiency of epidemiological investigations low, but also has a long time lag, and is very likely to produce more uncertainties, which greatly reduces the accuracy of the close matching results and puts great pressure on the epidemic prevention and control work.

[0004] Therefore, the existing methods for identifying and screening close contacts still need to be improved and developed. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a method and system for intelligent collection and matching of close contact information based on epidemic investigation bracelets, which can realize automatic collection and precise matching of close contact information of relevant personnel in key places at a lower cost during the epidemic prevention and control period, which can not only improve the efficiency of close matching, but also greatly reduce the uncertainty factors caused by time lag, and significantly improve the accuracy of close matching results.

[0006] The technical solution of the present invention is as follows: A method for intelligent collection and matching of close contact information based on an epidemic investigation bracelet, comprising the following steps: S210. Person A who enters a key location downloads and installs the epidemic survey applet on his / her smartphone, fills in personal information according to the instructions of the epidemic survey applet, and turns on the Bluetooth and WiFi functions of his / her smartphone; S220, the epidemic investigation data collection module in the epidemic investigation applet collects relevant information including the name, ID number, and mobile phone number of the relevant person A, and the data reporting module in the epidemic investigation applet uploads the relevant information collected by the epidemic investigation data collection module to the risk exposure personnel database of the epidemic investigation cloud platform; in the subsequent service links, the relevant person A needs to use the code scanning module in the epidemic investigation applet to scan the internal venue code to enter the service area inside the key venue; S230. Personnel B in key places wears an epidemic investigation bracelet and binds personal information. When person A uses the code scanning module in the epidemic investigation applet to scan the internal place code and enter the service area of ​​person B to do business, the epidemic investigation cloud platform triggers the epidemic investigation bracelet worn by person B to start the listening mode after receiving the code scanning information uploaded by the epidemic investigation applet. The WiFi scanning module and Bluetooth scanning module in the epidemic investigation bracelet automatically collect the device identification, signal strength and timestamp data of the WiFi devices and Bluetooth devices around person B at the set frequency and transmit them to the close contact data collection and processing module in the epidemic investigation bracelet. The close contact data collection and processing module stores the data in the epidemic investigation bracelet worn by person B as the close contact information of person B in time series, and reports it to the close contact occurrence information database of the epidemic investigation cloud platform at regular intervals. S240. When relevant person A leaves the key place after completing his business, he shall exit the epidemic investigation applet and turn off the Bluetooth and WiFi functions of the smartphone he carries with him; S250, the health sign monitoring sensor in the epidemic investigation bracelet worn by the relevant person B automatically collects the health sign data of the relevant person B according to the collection frequency issued by the epidemic investigation cloud platform, and the health sign data collection and processing module in the epidemic investigation bracelet uploads the health sign data of the relevant person B collected by the health sign monitoring sensor to the health sign monitoring library of the epidemic investigation cloud platform; S260. When the health sign monitoring module of the epidemic investigation cloud platform detects that the health sign data of the relevant person B is abnormal, an alarm message is sent to the cloud platform administrator. The cloud platform administrator contacts the relevant person B for health diagnosis and isolation through the personal information uploaded by his epidemic investigation bracelet, and uploads the health diagnosis result to the close contact query and matching module of the epidemic investigation cloud platform. If the health diagnosis result is a confirmed case, the close contact query and matching module is automatically triggered to conduct close contact screening; S270. The close contact query matching module first exports the device identification information and close contact information related to the relevant person B from the close contact occurrence information database in the chronological order of the query time window period to form a close contact query index table, and then automatically matches the device identification and personnel information of the close contact query index table with the risk-exposed person database, and automatically calculates the distance between the relevant person B and the relevant person A based on the signal strength of the WiFi devices and Bluetooth devices around the relevant person B, and generates a close contact information table for the epidemiological investigation related to the relevant person B.

[0007] The method for intelligent collection and matching of close contact information based on the epidemic investigation bracelet, wherein: the relevant person A who enters the key place wears an epidemic investigation bracelet to replace the smart phone he carries with him to download, install and use the epidemic investigation applet, includes the following steps: S210: The personal information of the relevant person A who enters the key place is registered under the guidance of the internal staff of the key place, and is bound to the bracelet information of the epidemic investigation bracelet worn by the person; S220, the epidemic investigation data collection module in the epidemic investigation bracelet of relevant person A collects relevant information of relevant person A, and the data reporting module in the epidemic investigation applet uploads the relevant information collected by the epidemic investigation data collection module to the risk exposure personnel database of the epidemic investigation cloud platform. After receiving the uploaded relevant information, the epidemic investigation cloud platform triggers the epidemic investigation bracelet of relevant person A to start the broadcast mode, so that the Bluetooth scanning module in the epidemic investigation bracelet of relevant person A sends the broadcast protocol at the set frequency; in the subsequent service links, relevant person A can enter the service area inside the key place only by relying on the epidemic investigation bracelet he wears; S230. On the premise that relevant person B in the key place wears an epidemic investigation bracelet and binds personal information, when relevant person A enters the service area of ​​relevant person B to do business, the broadcast protocol continuously sent by the epidemic investigation bracelet of relevant person A triggers the epidemic investigation bracelet worn by relevant person B to start the listening mode. The WiFi scanning module and Bluetooth scanning module in the epidemic investigation bracelet automatically collect the device identification, signal strength and timestamp data of the WiFi devices, Bluetooth devices and the epidemic investigation bracelet worn by relevant person A around relevant person B according to the set frequency, and transmit them to the close contact data collection and processing module in the epidemic investigation bracelet of relevant person B. The close contact data collection and processing module stores the data in the epidemic investigation bracelet worn by relevant person B as the close contact information of relevant person B in time series, and reports it to the close contact occurrence information database of the epidemic investigation cloud platform at regular intervals; S240. When relevant person A leaves the key place after doing business, he takes off the epidemic investigation bracelet and returns it to the internal staff of the key place. The internal staff of the key place unbinds the relevant person A from the bracelet information on the epidemic investigation cloud platform and turns off the broadcast mode of the epidemic investigation bracelet; S250, the health sign monitoring sensor in the epidemic investigation bracelet worn by the relevant person B automatically collects the health sign data of the relevant person B according to the collection frequency issued by the epidemic investigation cloud platform, and the health sign data collection and processing module in the epidemic investigation bracelet uploads the health sign data of the relevant person B collected by the health sign monitoring sensor to the health sign monitoring library of the epidemic investigation cloud platform; S260. When the health sign monitoring module of the epidemic investigation cloud platform detects that the health sign data of the relevant person B is abnormal, an alarm message is sent to the cloud platform administrator. The cloud platform administrator contacts the relevant person B for health diagnosis and isolation through the personal information uploaded by his epidemic investigation bracelet, and uploads the health diagnosis result to the close contact query and matching module of the epidemic investigation cloud platform. If the health diagnosis result is a confirmed case, the close contact query and matching module is automatically triggered to conduct close contact screening; S270, the close contact query matching module first exports the device identification information and close contact information related to the relevant person B from the close contact occurrence information database according to the time sequence of the query time window period to form a close contact query index table, and then automatically matches the device identification and personnel information of the close contact query index table with the risk-exposed person database, and automatically calculates the distance between the relevant person B and the relevant person A based on the signal strength of the WiFi devices, Bluetooth devices and the epidemic investigation bracelet worn by the relevant person A around the relevant person B, and generates an epidemic investigation close contact information table related to the relevant person B.

[0008] The method for intelligent collection and matching of close contact information based on the epidemic investigation bracelet, wherein: it also includes step S280, the cloud platform administrator contacts the corresponding relevant person A from the epidemic investigation close contact information table related to the relevant person B for health diagnosis and isolation treatment, and uploads the health diagnosis result of the relevant person A to the close contact query and matching module of the epidemic investigation cloud platform. If the health diagnosis result of the relevant person A is also a confirmed case, the close contact query and matching module is automatically triggered to conduct a new round of close contact screening for the relevant person A.

[0009] The method for intelligently collecting and matching close contact information based on the epidemic investigation bracelet, wherein: in the step S260, it also includes the cloud platform administrator manually triggering the close contact query and matching module to actively conduct close contact screening on the relevant person B or the relevant person A.

[0018] Figure 1 It is an architectural block diagram of an embodiment of the close contact information intelligent collection and matching system based on the epidemic investigation bracelet of the present invention. DETAILED DESCRIPTION

[0019] The specific implementation modes and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention and are not used to limit the specific implementation modes of the present invention.

[0020] The present invention is based on the method for intelligent collection and matching of close contact information of epidemic investigation bracelets, and takes the intelligent collection and matching of close contact information between patients who need to enter and exit the infectious disease hospital (i.e., relevant personnel A entering and exiting key places, the same below) and medical staff in the infectious disease hospital (i.e., relevant personnel B in key places, the same below) during the epidemic prevention and control period as an example to illustrate. Mainly, unit place codes and internal place codes with corresponding place information are posted at the entrance of the infectious disease hospital, various departments, wards, inpatient departments, etc. In addition to measuring body temperature in accordance with the requirements of local epidemic prevention policies, patients also need to use the WeChat APP in their smart phones to scan the unit place code and travel code, and can enter the infectious disease hospital only after meeting the requirements.

[0021] Step S210: The patient downloads and installs the epidemic survey applet on his / her smart phone, calls the epidemic survey applet by scanning the epidemic survey QR code, fills in personal information according to the instructions of the epidemic survey applet, and turns on the Bluetooth and WiFi functions of his / her smart phone.

[0022] Step S220: The flow survey data collection module (i.e. Figure 1 The small program in the epidemic investigation applet collects the name, ID number, telephone number, mobile device identification code (such as MAC address, etc.), venue name, entry time and number and other related information of the patient. The data reporting module in the epidemic investigation small program uploads the relevant information of the patient collected by the epidemic investigation data collection module to the risk exposure personnel database of the epidemic investigation cloud platform (i.e. Figure 1 in the database of possible close contacts); in the subsequent registration, medical treatment, examination and medication collection processes, patients need to use the code scanning module in the epidemic investigation mini program to scan the internal place code to enter the various departments, wards and inpatient departments inside the infectious disease hospital (that is, to enter the service areas inside key places). The internal place codes posted at the entrances of various departments, wards and inpatient departments inside the infectious disease hospital are generated by the epidemic investigation cloud platform based on the corresponding information of the departments, wards and inpatient departments inside the infectious disease hospital.

[0023] Step S230: All medical staff who visit various departments of the infectious disease hospital must wear an epidemic investigation bracelet and bind their personal information. When the patient uses the code scanning module in the epidemic investigation applet to scan the internal location code to enter the corresponding department for treatment (i.e., enter the service area of ​​the relevant personnel B to serve), the epidemic investigation cloud platform triggers the epidemic investigation bracelet worn by the medical staff of the department to start the listening mode after receiving the code scanning information uploaded by the epidemic investigation applet. The WiFi scanning module and Bluetooth scanning module in the epidemic investigation bracelet scan the internal location code according to the set frequency (for example, seconds or minutes). The data of device identification, signal strength and timestamp of WiFi devices and Bluetooth devices around the medical staff on duty are automatically collected (at the clock level) and transmitted to the close contact data collection and processing module in the epidemic investigation bracelet. The close contact data collection and processing module stores the data in a time series in the epidemic investigation bracelet worn by the medical staff on duty (i.e., relevant personnel B) as the close contact information of the medical staff on duty, and reports it to the close contact information database of the epidemic investigation cloud platform at regular intervals. The reporting period (for example, 5 minutes, etc.) can be determined by the reporting strategy issued by the epidemic investigation cloud platform.

[0024] Step S240: When the patient leaves the infectious disease hospital after examination and medication, he or she can exit the epidemic investigation applet and turn off the Bluetooth and WiFi functions of the smartphone he or she carries with him or her.

[0025] Step S250, the health sign monitoring sensors in the epidemic investigation bracelets worn by the medical staff in various departments of the infectious disease hospital automatically collect the health sign data of the medical staff at the epidemic investigation cloud platform according to the collection frequency (for example, 10 minutes / time) issued by the epidemic investigation cloud platform. The health sign data include the body temperature, heart rate, blood pressure and blood oxygen data of the medical staff collected by the thermoelectric infrared temperature sensor and the photoplethysmography (PPG) sensor set in the epidemic investigation bracelet. The health sign data collection and processing module in the epidemic investigation bracelet uploads the health sign data of the medical staff collected by the health sign monitoring sensors to the health sign monitoring library of the epidemic investigation cloud platform.

[0026] Step S260: When the health sign monitoring module of the epidemic investigation cloud platform detects that the health sign data of the medical staff on the visit are abnormal (for example, the body temperature exceeds 37°C), an alarm message of "XX medical staff on the visit has abnormal body temperature" is issued to the cloud platform administrator. The cloud platform administrator contacts the medical staff on the visit through the personal information uploaded by their epidemic investigation bracelet to conduct health diagnosis (such as nucleic acid testing, etc.) and isolation treatment, and uploads the health diagnosis results to the close contact query and matching module of the epidemic investigation cloud platform. If the health diagnosis result is a confirmed case, the close contact query and matching module is automatically triggered to conduct close contact screening.

[0027] Step S270, the close contact query matching module first exports the device identification information and close contact information related to the visiting medical staff from the close contact occurrence information database in the chronological order of the query time window period (generally 14 days) to form a close contact query index table, and then automatically matches the device identification and personnel information of the close contact query index table with the risk-exposed personnel database, and automatically calculates the distance between the visiting medical staff and the patient based on the signal strength of the WiFi devices and Bluetooth devices around the visiting medical staff, and generates an epidemiological investigation close contact information table related to the visiting medical staff.

[0028] Step S280: The cloud platform administrator contacts the corresponding patient from the epidemiological close contact information table for health diagnosis and isolation treatment, and uploads the health diagnosis result of the patient to the close contact query and matching module of the epidemiological investigation cloud platform. If the health diagnosis result of the patient (i.e., the relevant person A who enters and exits the key places) is also a confirmed case, the close contact query and matching module is automatically triggered to conduct a new round of close contact screening for the patient.

[0029] As another technical solution, for infectious disease hospitals with the conditions, patients entering the infectious disease hospitals can also be required to wear epidemic investigation bracelets, so that they no longer need to use their smartphones to download, install and call epidemic investigation applets by scanning codes, etc., to facilitate medical treatment for elderly people who cannot use smartphones.

[0030] Step S210: After the patient enters the infectious disease hospital, the personal information registered under the guidance of the internal staff of the infectious disease hospital (i.e. the internal staff of key places) is bound to the bracelet information of the epidemic investigation bracelet he wears.

[0031] Step S220, the close contact data collection and processing module in the patient's epidemiological investigation bracelet collects relevant information such as the patient's name, ID number, telephone number, venue name, entry time and number, and uploads the relevant information of the patient to the risk-exposed personnel database of the epidemiological investigation cloud platform. After receiving the uploaded relevant information, the epidemiological investigation cloud platform triggers the patient's epidemiological investigation bracelet to start the broadcast mode, so that the Bluetooth scanning module in the patient's epidemiological investigation bracelet sends the broadcast protocol at a set frequency (for example, seconds); in subsequent registration, medical treatment, examination and medication collection, the patient can enter the various departments, wards and inpatient departments of the infectious disease hospital only by relying on the epidemiological investigation bracelet he wears, and no longer needs to use a smartphone to download, install and use the scanning module in the epidemiological investigation applet to enter by scanning the internal venue code.

[0032] Step S230: Medical staff in various departments of the infectious disease hospital must wear an epidemic investigation bracelet and bind their personal information. When the patient (i.e., the relevant person A entering the key place) enters the corresponding department for treatment after registration, the broadcast protocol continuously sent by the patient's epidemic investigation bracelet triggers the epidemic investigation bracelet of the medical staff in the department to start the listening mode, so that the WiFi scanning module and Bluetooth scanning module in the epidemic investigation bracelet of the medical staff (i.e., the relevant person B in the key place) automatically collect the surrounding information of the medical staff at the set frequency (for example, seconds or minutes). The device identification, signal strength and timestamp of WiFi devices and Bluetooth devices (including the epidemic investigation bracelets worn by patients) are transmitted to the close contact data collection and processing module in the epidemic investigation bracelets of the medical staff. The close contact data collection and processing module stores the relevant information in a time series as the close contact information of the medical staff (i.e. the relevant personnel B) in the epidemic investigation bracelet worn by the medical staff, and reports it to the close contact information database of the epidemic investigation cloud platform at regular intervals. The reporting period (for example, 5 minutes) can be determined by the reporting strategy issued by the epidemic investigation cloud platform.

[0033] Step S240: When the patient leaves the infectious disease hospital after examination and medication, he / she takes off the epidemic investigation bracelet and returns it to the internal staff of the infectious disease hospital. The internal staff of the infectious disease hospital unbinds the patient's information from the bracelet information on the epidemic investigation cloud platform and turns off the broadcast mode of the epidemic investigation bracelet.

[0034] The following parts are basically the same as the previous solution (such as step S250 and step S280), because the epidemic investigation bracelet worn by the patient is also a Bluetooth device when the broadcast mode is turned on.

[0035] Step S260: When the health sign monitoring module of the epidemic investigation cloud platform detects that the health sign data of the medical staff on duty are abnormal and the diagnosis result is a confirmed case, the close contact query and matching module is automatically triggered to conduct close contact screening.

[0036] Step S270, the close contact query matching module first exports the device identification information and close contact information related to the visiting medical staff from the close contact occurrence information database in the chronological order of the query time window period (generally 14 days) to form a close contact query index table, and then automatically matches the device identification and personnel information of the close contact query index table with the risk-exposed personnel database, and automatically calculates the distance between the visiting medical staff and the patient based on the signal strength of the WiFi devices and Bluetooth devices around the visiting medical staff (including the epidemic investigation bracelet worn by the patient), and also generates an epidemic investigation close contact information table related to the visiting medical staff.

[0037] In addition, the triggering of the close contact query matching module in step S260 and step S270 can also be manually triggered by the cloud platform administrator to actively conduct close contact screening on the medical staff attending various departments of the infectious disease hospital (i.e., the relevant personnel B inside the key places) or the patients entering and leaving the infectious disease hospital (i.e., the relevant personnel A entering and leaving the key places); for example, for the medical staff attending the fever clinic of the infectious disease hospital, the platform administrator can, based on the internal regulations of the infectious disease hospital and in combination with the requirements of the local epidemic prevention policy, actively conduct close contact screening on the medical staff who have received confirmed cases within one week.

[0038] Based on the above-mentioned close contact information intelligent collection and matching method, the present invention also proposes a close contact information intelligent collection and matching system based on an epidemic investigation bracelet, which is composed of an epidemic investigation applet, an epidemic investigation bracelet and an epidemic investigation cloud platform; wherein, the epidemic investigation applet is composed of a code scanning module, an epidemic investigation data collection module and a data reporting module, and the epidemic investigation applet is used to be installed in smart phones carried by inpatients, accompanying personnel and isolated personnel (i.e., relevant personnel A who need to enter and exit key places) who need to enter and exit key places such as infectious disease hospitals, temporary hospitals or isolation hotels; the epidemic investigation bracelet is internally provided with a WiFi scanning module, a Bluetooth scanning module, a close contact data collection and processing module, a health sign monitoring sensor and a health sign data collection and processing module. The epidemic investigation bracelet is used to be worn on the wrists of medical staff, managers, staff and auxiliary personnel (i.e., relevant personnel B in key places) in key places such as infectious disease hospitals, temporary hospitals or isolation hotels. It can also be worn on the wrists of inpatients, caregivers and quarantined personnel (i.e., relevant personnel A who need to enter and exit key places) who need to enter and exit key places such as infectious disease hospitals, temporary hospitals or isolation hotels, as an alternative to downloading, installing and using the epidemic investigation applets on their portable smartphones; the epidemic investigation cloud platform consists of a risk-exposed personnel database, a close contact information database, a health sign monitoring database, a health sign monitoring module and a close contact query and matching module.

[0039] The code scanning module in the epidemic investigation applet is used for relevant personnel A to enter the service area inside the key place by scanning the internal venue code. The internal venue code is generated by the epidemic investigation cloud platform based on the service area information inside the key place, and posted at the entrance of the corresponding service area inside the key place; the epidemic investigation data collection module is used to collect relevant information such as the name, ID number, telephone number, mobile device identification code (such as MAC address, etc.), venue name, entry time and number of relevant personnel A; the data reporting module is used to upload the relevant information of relevant personnel A collected by the epidemic investigation data collection module to the risk exposure personnel database of the epidemic investigation cloud platform.

[0040] The WiFi scanning module and Bluetooth scanning module of the epidemic investigation bracelet worn on the wrist of relevant person B inside the key place are used to automatically collect the device identification, signal strength and timestamp data of the WiFi devices and Bluetooth devices around relevant person B at a set frequency (for example, seconds or minutes) when relevant person A enters the key place and the epidemic investigation bracelet is triggered by the epidemic investigation cloud platform to start the listening mode, and transmit it to the close contact data collection and processing module; the close contact data collection and processing module is used to store the data as the close contact information of relevant person B in a time series in the epidemic investigation bracelet worn by relevant person B, and report it to the close contact information database of the epidemic investigation cloud platform at regular intervals.

[0041] The Bluetooth scanning module inside the epidemic investigation bracelet worn on the wrist of relevant person A who enters and exits key places is used to continuously send broadcast protocols at a set frequency (for example, seconds) when relevant person A enters the key place and the epidemic investigation cloud platform triggers the epidemic investigation bracelet to start the broadcast mode.

[0042] The health sign monitoring sensor is used only when it is worn on the wrist of relevant personnel B inside key places, and the health sign data of isolated persons is collected regularly according to the collection frequency issued by the epidemic investigation cloud platform. The health sign data collection and processing module is used only when it is worn on the wrist of relevant personnel B inside key places, and the health sign data of isolated persons collected by the health sign monitoring sensor is uploaded to the epidemic investigation cloud platform.

[0043] The epidemic investigation cloud platform is used to collect location information collected by scanning and generating internal place codes based on the service area information inside key places. The internal place codes are used to be posted at the entrance of the service area inside the key places after printing.

[0044] The epidemic investigation cloud platform is also used to trigger the epidemic investigation bracelet worn on the wrist of relevant personnel A to start the broadcast mode when relevant personnel A enters the key place, and to trigger the epidemic investigation bracelet worn on the wrist of relevant personnel B to start the listening mode when relevant personnel A scans the internal place code through the scanning module in the epidemic investigation applet to enter the service area of ​​relevant personnel B.

[0045] The health sign monitoring module in the epidemic investigation cloud platform is used to monitor the health sign data of the relevant personnel B, and when an abnormality occurs (for example, the body temperature exceeds 37°C), an alarm message of "XX medical staff has abnormal body temperature" is issued to the cloud platform administrator.
