Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an endoscope cleaning, disinfection and tracing system. Background Art

[0002] Endoscope disinfection refers to the method of eliminating pathogenic microorganisms on endoscopes. Endoscopes are increasingly used, but as an invasive diagnostic and treatment method, the problem of possible infection transmission is increasingly attracting attention. In order to avoid non-standard endoscope disinfection or non-standard disinfection time, an endoscope disinfection traceability system is usually used to collect data and then analyze whether the endoscope disinfection meets the standards.

[0003] From a process perspective, most of the endoscope cleaning, disinfection and traceability systems currently used do not adopt a "closed-loop" process, that is, they cannot monitor and trace the entire process. The overall process of most endoscope cleaning, disinfection and traceability systems starts when the endoscope is taken to the cleaning room and ends when the endoscope completes the cleaning and disinfection process. That is, the current endoscope disinfection traceability systems can only monitor the cleaning and disinfection process of endoscopes, but cannot monitor the endoscope's outbound delivery and the use of endoscopes, and it is difficult to ensure that the endoscope is not contaminated during use or transportation. And because the process of the endoscope cleaning, disinfection and traceability system ends at the end of the endoscope cleaning and disinfection process, it is impossible to monitor whether the endoscope is directly used after cleaning and disinfection without being put into storage or whether it is contaminated during the storage process.

[0004] From the information point of view, the current endoscope cleaning and disinfection traceability system is designed in the form of local database + hospital database; and this design will bring great data calculation and storage pressure, which is mainly reflected in the following two aspects:

[0005] 1. After connecting to the hospital database, the independence and database stability of the endoscope cleaning and disinfection traceability system cannot be guaranteed; due to the large amount of information in the hospital database, the existing endoscope cleaning and disinfection traceability system needs to consume a lot of manpower and material resources to maintain the stability of the database.

[0006] 2. The local database is not easy to synchronize, and may cause the data after the system upgrade to be unable to synchronize.

[0007] From the perspective of system architecture, the current endoscope cleaning, disinfection and traceability system uses a centralized cluster; however, centralized clusters make data calculation difficult, slow, and data can be tampered with, leading to easy loss. Summary of the invention

[0008] In order to solve the problems existing in the above-mentioned prior art, the present invention provides an endoscope cleaning and disinfection traceability system, which is intended to solve the problems that the current endoscope cleaning and disinfection monitoring has blind spots, and the use of a centralized cluster approach makes data calculation difficult and slow, and data can be tampered with and easily lost.

[0009] An endoscope cleaning and disinfection traceability system, including an endoscope use traceability system constructed by a physical layer, an application layer, and a blockchain traceability platform layer;

[0010] The physical layer includes a data acquisition unit for collecting data, the application layer includes a central processing unit for data processing and a cleaning and disinfection monitoring unit for monitoring whether the endoscope disinfection meets the disinfection standards; the blockchain traceability platform layer includes a blockchain traceability unit, an endoscope use traceability unit and a real-time display unit;

[0011] The data acquisition unit is used to obtain data from the RFID card reader operating system and the endoscope disinfection system;

[0012] The central processing unit pre-processes the data collected by the data collection unit and stores the data in a database, and the database receives the calling instruction of the central processing unit for display in the real-time display unit;

[0013] The cleaning and disinfection monitoring unit is used to obtain the data pre-processed by the central processing unit, and determine whether the cleaning and disinfection processes in the data and the disinfection time, disinfectant and cleaning and disinfection equipment safety conditions corresponding to each disinfection process meet the national standards;

[0014] The blockchain tracing unit is used for tracing and acquiring data;

[0015] The endoscope use tracing unit is used to obtain the patient ID and endoscope ID in the hospital database, and obtain the cleaning and disinfection information provided by the central processing unit to manage and trace the use of the endoscope. The hospital can directly obtain all patient information through the patient ID and obtain all endoscope information through the endoscope ID. Here, the patient ID and endoscope ID are both provided by the hospital. The purpose is to import the two information from the hospital database, and all patient information can be obtained based on the patient ID, and all endoscope information can be obtained based on the endoscope ID. The reason for choosing two IDs is to ensure the independence of the system while ensuring that the system will not crash due to excessive data in the database.

[0016] Preferably, the RFID card reader operating system is composed of RFID card reader operating software, endoscope card, operator card, RFID card reader and server data docking interface;

[0017] The RFID card reader is used to obtain information of the endoscope and the operator's card, and transmit the data to the RFID card reader operating software based on the docking interface of the server data.

[0018] Preferably, the operating permissions of the operator card are set in the RFID card swiper operating software. The RFID card swiper operating software determines whether the cardholder has the corresponding operating permissions based on the information of the operator card obtained by the RFID card swiper. If not, the corresponding operation cannot be performed. If so, the corresponding data will be recorded in the database and the endoscope usage tracing unit.

[0019] Preferably, the docking interface of the server data is a data transmission interface between the RFID card reader and the computer. After the RFID card reader is connected to the computer, a data connection is established between the RFID card reader operating software and the endoscope cleaning, disinfection and traceability system through websocket.

[0020] Preferably, the blockchain traceability unit is composed of a blockchain main chain, a data collection sub-chain, a central processing sub-chain, and a cleaning and disinfection monitoring sub-chain; the blockchain main chain is connected in series with the data collection sub-chain, the central processing sub-chain, and the cleaning and disinfection monitoring sub-chain;

[0021] The data collection subchain, central processing subchain, and cleaning and disinfection monitoring subchain upload the core nodes and key data to the blockchain main chain according to the timestamp, and store the "marked" data in the blockchain main chain;

[0022] The "marked" data refers to the timestamp + the record node of the previous layer. The record node does not have specific data and calculation functions, but only records which layer the "mark" comes from. According to the "marked" information, the information of a certain time and a certain layer can be directly traced back.

[0023] The data acquisition subchain stores the data collected by the data acquisition unit; the central processing subchain stores the data processed by the central processing unit; and the cleaning and disinfection monitoring subchain stores the data discarded by the cleaning and disinfection monitoring unit.

[0024] Preferably, the data acquisition unit uploads all acquired data to the data acquisition subchain for storage, and automatically uploads the data to the blockchain main chain after integrating and formatting the data based on the data acquisition subchain.

[0025] Preferably, the database includes a cache database and a main database; after the central processing unit processes the received data, it first stores the data in the cache database and then stores it in the main database;

[0026] After the main database and cache database store the data, the data persistence operation will be performed; and the data will be uploaded to the central processing subchain.

[0027] The main database is a Mysql database; the cache database is a Redis database.

[0028] Preferably, the real-time display unit includes a data query function and a cleaning and disinfection real-time display function;

[0029] The data query function is implemented based on the query interface provided by the blockchain main chain. The query interface provided by the blockchain main chain queries the "marks" stored in the timeline of all blockchain main chains, and traces the data of the corresponding sub-chain according to the "marks", and displays the traced data in real time;

[0030] The real-time display function of cleaning and disinfection is realized based on the cleaning and disinfection monitoring unit. The cleaning and disinfection monitoring unit provides a data interface, and the data is visualized and then displayed through the real-time display unit.

[0031] The beneficial effects of the present invention include:

[0032] 1. The present invention introduces blockchain technology into the endoscope use data traceability and endoscope cleaning and disinfection traceability system, making the entire system decentralized, data immutable, traceable, open and anonymous; in actual hospital scenarios, due to the large amount of endoscope cleaning, disinfection and management data, the cost and technical difficulty of uploading the data of all monitoring stations to the central server for unified operation are too high. The decentralized characteristics of blockchain can well reduce the cost and technical difficulty. And the immutability and traceability of blockchain data can well ensure the authenticity of the data, and the tracing process data can be comprehensively analyzed. The openness and anonymity ensure both the disclosure of key data and the personal information of patients.

[0033] 2. The present invention realizes the monitoring and tracing of the whole process from leaving the warehouse, assigning the endoscope to the patient and registering the patient ID in the system, starting the cleaning and disinfection process, ending the cleaning and disinfection process, and entering the warehouse. The patient's ID, cleaning and disinfection process, and cleaning and disinfection operator are associated with the endoscope ID to ensure traceability later. At the same time, in the cleaning and disinfection procedure, the cleaning and disinfection of the endoscope is strictly controlled, and the endoscopes that do not meet the cleaning and disinfection standards will be recorded, thereby ensuring that all endoscopes can meet the cleaning and disinfection standards.

[0034] 3. This application uses MySQL database and redis cache database, so that after the data is entered, the data will be automatically stored in the MySQL database and redis cache database, thereby realizing double data backup and high-speed data reading; since both the database and the cache database are implemented based on cloud computing, there is no need for local developers to perform database updates and database backup operations, which reduces the development difficulty and ensures data integrity while achieving cloud synchronization.

[0035] Different from the traditional medical data tracing system that uses local database, this product uses cloud computing services brought by cloud servers, which ensures data integrity while ensuring data backup and easy modification. It reduces the time for developers to configure related development files and facilitates developers to develop based on the high computing rate and high server functions of cloud computing.

[0036] 4. The present invention uses an RFID-based card reader, which is associated with the system. During the actual use of the system, the endoscope cleaning operator can directly manage the creation, start and end of the cleaning process through the card reader. And synchronize the display on the traceability monitoring station. That is, medical staff and related operators do not need to design code work or keyboard operation, they only need to swipe in cards with different permissions through the card reader to complete the whole process of outbound, new cleaning process, start cleaning process, and warehousing.

[0040] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0041] The following is combined with Figure 1To the attached Figure 3 As shown, the embodiments of the present invention are further described in detail:

[0042] An endoscope cleaning and disinfection traceability system, including an endoscope use traceability system constructed by a physical layer, an application layer, and a blockchain traceability platform layer;

[0043] The physical layer includes a data acquisition unit for collecting data, the application layer includes a central processing unit for data processing and a cleaning and disinfection monitoring unit for monitoring whether the endoscope disinfection meets the disinfection standards; the blockchain traceability platform layer includes a blockchain traceability unit, an endoscope use traceability unit and a real-time display unit;

[0044] The data acquisition unit is used to obtain data from the RFID card reader operating system and the endoscope disinfection system;

[0045] The central processing unit pre-processes the data collected by the data collection unit and stores the data in a database, and the database receives the calling instruction of the central processing unit for display in the real-time display unit;

[0046] The cleaning and disinfection monitoring unit is used to obtain the data pre-processed by the central processing unit, and determine whether the cleaning and disinfection processes in the data and the disinfection time corresponding to each disinfection process meet the national standards;

[0047] For manual cleaning and disinfection equipment, that is, equipment that implements the endoscope cleaning and disinfection process through manual operation, the cut-off time needs to be determined and judged by swiping the RFID endoscope card every time the cleaning and disinfection process is switched, and uploaded to the cleaning and disinfection monitoring subchain for data non-tamperable storage.

[0048] The blockchain tracing unit is used for tracing and acquiring data;

[0049] The endoscope use tracing unit is used to obtain the patient ID and endoscope ID in the hospital database, and obtain the cleaning and disinfection information provided by the central processing unit to manage and trace the use of the endoscope. The hospital can directly obtain all patient information through the patient ID and obtain all endoscope information through the endoscope ID. Here, the patient ID and endoscope ID are both provided by the hospital. The purpose is to import the two information from the hospital database, and all patient information can be obtained based on the patient ID, and all endoscope information can be obtained based on the endoscope ID. The reason for choosing two IDs is to ensure the independence of the system while ensuring that the system will not crash due to excessive data in the database.

[0050] The RFID card reader operating system is composed of RFID card reader operating software, endoscope card, operator card, RFID card reader and server data docking interface;

[0051] The RFID card reader is used to obtain information of the endoscope and the operator's card, and transmit the data to the RFID card reader operating software based on the docking interface of the server data.

[0052] The operating permissions of the operator card are set in the RFID card reader operating software. The RFID card reader operating software determines whether the cardholder has the corresponding operating permissions based on the information of the operator card obtained by the RFID card reader. If not, the corresponding operation cannot be performed. If so, the corresponding data will be recorded in the database and the endoscope usage tracing unit.

[0053] The docking interface of the server data is a data transmission interface between the RFID card reader and the computer. After the RFID card reader is connected to the computer, a data connection is established between the RFID card reader operating software and the endoscope cleaning, disinfection and tracing system through websocket.

[0054] The blockchain traceability unit is composed of a blockchain main chain, a data collection sub-chain, a central processing sub-chain, and a cleaning and disinfection monitoring sub-chain; the blockchain main chain is connected in series with the data collection sub-chain, the central processing sub-chain, and the cleaning and disinfection monitoring sub-chain;

[0055] The data collection subchain, central processing subchain, and cleaning and disinfection monitoring subchain upload the core nodes and key data to the blockchain main chain according to the timestamp, and store the "marked" data in the blockchain main chain; the "marked" data refers to the timestamp + the record node of the previous layer. The record node refers to a node that does not have specific data and calculation functions, but only records which layer the "mark" comes from. According to the "marked" information, the information situation at a certain time and a certain layer can be directly traced back.

[0056] The data acquisition subchain stores the data collected by the data acquisition unit; the central processing subchain stores the data processed by the central processing unit; and the cleaning and disinfection monitoring subchain stores the data discarded by the cleaning and disinfection monitoring unit.

[0057] The data acquisition unit uploads all acquired data to the data acquisition subchain for storage, and automatically uploads the data to the blockchain main chain after integrating and formatting the data based on the data acquisition subchain;

[0058] The operator card is mainly responsible for switching the process, and the endoscope card is mainly responsible for the operation within the specific process;

[0059] If the endoscope needs to be switched, such as when it is shipped out of the warehouse, allocated to patients, or when cleaning and disinfection begins, the operator card needs to be used on the RFID card reader to perform the operation. The endoscope can only be used after the data is recorded in the data collection sub-chain.

[0060] The endoscope card is an endoscope ID card assigned to each endoscope, ensuring the principle that one endoscope card corresponds to one endoscope. During each cleaning and disinfection process, if you need to switch to the next process, for example, after the "initial wash" is completed, you need to perform the "alcohol wash" operation, then you need to swipe the endoscope card for data recording and data verification. If the "initial wash" meets the relevant cleaning and disinfection standards, you can proceed to the next step. If it does not meet the relevant cleaning and disinfection standards, the system will automatically report an error and record the error in the cleaning and disinfection sub-chain, and the next cleaning and disinfection process cannot be performed.

[0061] The database includes a cache database and a main database; after the central processing unit processes the received data, it first stores the data in the cache database and then stores it in the main database;

[0062] After the main database and cache database store the data, the data persistence operation will be performed; and the data will be uploaded to the central processing subchain.

[0063] The main database is a Mysql database; the cache database is a Redis database.

[0064] When the Redis database automatically checks the data in the MySQL database, if it is inconsistent, it will directly use the data in the Redis database; if it is consistent, the data in the MySQL database will be used. Since the Redis database has the characteristics of high-speed caching, it can achieve fast storage and fast reading and writing. Therefore, the data storage process of first storing in the Redis database and then storing in the MySQL database can ensure the timeliness of the data related to endoscope cleaning and disinfection while ensuring the uniformity of the data.

[0065] The data processing content and form of the central processing unit are as follows:

[0066] After processing the data, the database system of the endoscope cleaning and disinfection traceability system will pass the data to the backend server, that is, the Spring Boot part. In the backend Spring Boot framework, there are four layers of data transmission, namely the Controller layer, the Service layer, the Mapper layer (Dao layer), and the Model layer. The data is first written in the Mysql database and accessed through the Model layer. The Model layer provides entity classes, and the provided entity classes correspond to the Mysql database tables one by one to achieve access. The CURD interface of the Mysql database is written in the Mapper layer, encapsulating the data persistence operation on the Mysql database. Data persistence, that is, converting the data model in memory into a storage model, is achieved by integrating the Mybatis-Plus framework through Spring Boot. The Mapper layer needs to be imported in the Service layer. The Service layer has interfaces and interface implementation methods. Therefore, the Mapper layer can be directly imported in the interface implementation class. The Service layer mainly stores business logic processing, that is, some operations on Mysql database processing. In the Controller layer, by responding to user requests, it is decided what view to use and what data to prepare for display.

[0067] After the backend operation is completed, the view is finally displayed to the user in the View layer based on the received data. The View layer connects to the front-end Vue.js framework through the template engine, and is rendered by the Vue.js framework and displayed on the user's browser.

[0068] The process of loading data into the backend server, processing it, and displaying it on the frontend does not involve data changes and writing, and the operation speed is too fast, so there is no need to upload it to the central processing subchain for tamper-proof storage. After the data processing of the central data unit is completed, the system will automatically start the process of the cleaning and disinfection monitoring unit and the endoscope use tracing unit.

[0069] The real-time display unit includes a data query function and a cleaning and disinfection real-time display function;

[0070] The data query function is implemented based on the query interface provided by the blockchain main chain. The query interface provided by the blockchain main chain queries the "marks" stored in the timeline of all blockchain main chains, and traces the data of the corresponding sub-chain according to the "marks", and displays the traced data in real time;

[0071] The real-time display function of cleaning and disinfection is realized based on the cleaning and disinfection monitoring unit. The cleaning and disinfection monitoring unit provides a data interface, and the data is visualized and then displayed through the real-time display unit.

[0072] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
