Description

Technical Field

[0001] This invention belongs to the field of smart home medical services, specifically a chronic disease monitoring system and method based on blockchain technology. Background Technology

[0002] Chronic non-communicable diseases are a group of diseases with insidious onset, long course and persistent symptoms, lack of definite evidence of infectious biological causes and complex etiologies. Common chronic diseases include hypertension, diabetes and hyperlipidemia. These diseases are often accompanied by serious complications and may even lead to the death of patients.

[0003] While existing technologies allow for rehabilitation treatment through family doctor services, the need for family doctors to collectively sign contracts with hundreds of households in their jurisdiction often prevents them from developing targeted treatment and supportive care strategies for patients with chronic diseases. This leads to family doctors being unable to promptly and effectively implement corresponding complication prevention measures based on the patients' physical conditions, hindering timely intervention for complications and impeding the recovery of chronic disease patients. Furthermore, in the era of advanced internet technology, patient medical record privacy is not adequately protected, resulting in the disclosure of patient information and causing significant impacts on patients' physical and mental well-being.

[0004] Blockchain is an emerging technology that has grown rapidly in my country in recent years. Relying on the immutability, decentralization, and uniqueness brought about by the blockchain structure, developers are exploring the application of blockchain technology in family medical services and are committed to developing a chronic disease monitoring system and method based on blockchain technology. Summary of the Invention

[0005] The purpose of this invention is to provide a chronic disease monitoring system and method based on blockchain technology, which helps doctors formulate targeted treatment and auxiliary treatment strategies, reduces the probability of complications in chronic disease patients, effectively prevents the occurrence of complications that lead to untimely rescue, and helps patients recover their health.

[0006] The technical solution adopted by the present invention to achieve the above objectives is: a chronic disease monitoring system based on blockchain technology, comprising: a medical assistant monitoring terminal, a medical blockchain system, and a user terminal;

[0007] The medical assistant monitoring terminal is used to wait for users to issue instructions to sign up for a package, and to retrieve and upload the health record information filled in by users for storage. It also marks key groups for designated users. Doctors develop and store targeted diagnosis and treatment strategies and auxiliary treatment strategies based on the actual physical condition of designated users.

[0008] The user terminal sends a contract package instruction to the medical assistance supervision terminal. Based on the contract service package feedback from the medical assistance supervision terminal, an electronic contractual relationship is formed. After filling in health record information, the user terminal waits for the medical assistance supervision terminal to access the data. At the same time, after the medical assistance supervision terminal completes the marking of key populations on the user terminal, the user terminal accesses the targeted diagnosis and treatment and auxiliary treatment strategies derived from the medical assistance supervision terminal.

[0009] The medical blockchain system is used to create a blockchain on which users' health record information is stored. It encrypts the medical information of users, including health record information, and executes smart contracts for access control, data verification, and privacy protection to ensure the security and privacy of patients' medical information.

[0010] Simultaneously, authorized medical assistant monitoring terminals can access and update user medical information containing health record information stored on the blockchain; and authorize corresponding medical assistant monitoring terminals to access and update user medical information containing health record information stored on the blockchain, to ensure the security and privacy protection of medical information exchanged between the medical assistant monitoring terminals and user terminals.

[0011] The medical assistant monitoring terminal includes: a member information management module, a contracted package management module, and a key population marking module;

[0012] The member information management module is used to retrieve and save the health record information filled in by the user.

[0013] The contracted service package management module is used to set up contracted service packages, which include at least the management of hypertension, diabetes, hyperlipidemia, severe mental disorders, tuberculosis, tumors, COPD, and stroke.

[0014] The key user group marking module is used to mark the type of the contracted service package corresponding to the user on the user side.

[0015] The user interface includes: a subscription package module and a health record module;

[0016] The contract package module is used to send a contract package instruction to the medical assistant supervision terminal and form an electronic contractual relationship based on the contract service package fed back by the medical assistant supervision terminal.

[0017] The health record module is used to fill in health record information and send it to the medical blockchain system for storage, waiting for the member information management module of the medical assistant supervision terminal to call it;

[0018] The health record information includes: name, place of residence, blood type, exposure history, allergy history, past medical history, family medical history, diet, alcohol and smoking status, occupational hazard exposure history, uploaded medical records, treatment information, medication information, and physical examination reports.

[0019] The medical blockchain system includes: a blockchain network, an identity verification module, a smart contract module, a data storage module, a data exchange module, and a data analysis module;

[0020] A blockchain network used to create and manage medical blockchain systems. The created blockchain network uses consensus algorithms to ensure the consistency and security of the blockchain.

[0021] The identity verification module is used to register and verify the identity of the medical assistant monitoring terminal;

[0022] The smart contract module is used to implement access control, data verification, and privacy protection;

[0023] The data storage module is used to store and manage users' health record information using a distributed storage mechanism to ensure data security and reliability.

[0024] The data exchange module is used to support data exchange and sharing between authorized medical assistant monitoring terminals;

[0025] The data analysis module is used to provide real-time statistics on health record information and to develop targeted diagnosis and treatment strategies based on the user's physical condition by using smart contracts and data analysis tools on the blockchain.

[0026] A regulatory method for a chronic disease monitoring system based on blockchain technology includes the following steps:

[0027] 1) The medical assistant monitoring terminal sets up contracted service packages, waiting for designated user terminals to call them;

[0028] 2) Users on the designated user terminal form an electronic contractual relationship with the contracted service package set by the medical assistant supervision terminal through the contracted package module. At the same time, users fill in health record information into the medical blockchain system through the health record module for storage, waiting for the medical assistant supervision terminal to call it.

[0029] 3) The medical assistant monitoring terminal retrieves health record information from the designated user terminal, uploads it to the member information management module for storage, and waits for the designated user terminal to be marked as a key population.

[0030] 4) Doctors and assistants select one or more items based on the member information of the designated user in the medical assistant management terminal to mark the designated user as a key population according to the marking type, and upload and store the information. Doctors then formulate targeted diagnosis and treatment and auxiliary treatment strategies based on the actual physical condition of the designated user, while waiting for the designated user terminal to call them.

[0031] In step 2), the user fills in health record information into the medical blockchain system through the health record module for storage, awaiting access from the medical assistant supervision terminal. This includes the following steps:

[0032] (1) Create a blockchain in the medical blockchain system; and register and verify the identity of the medical assistant supervisor on the blockchain;

[0033] (2) The smart contract module allows the medical assistant supervision end to store the health record information of the user on the medical blockchain; and executes smart contracts for access control, data verification and privacy protection through encryption algorithms and access control mechanisms to ensure the security and privacy protection of the patient's medical information;

[0034] (3) Authorized medical assistant monitoring terminals are allowed to access and update medical information containing user health record information stored on the blockchain;

[0035] (4) The medical assistant supervision terminal records and tracks the access and update records of users' medical information on the blockchain;

[0036] (5) The data storage module protects users’ medical information from unauthorized access and tampering through encryption algorithms and distributed storage, providing a fast and secure way for patients and medical institutions to exchange data.

[0037] In step (2), the smart contract module allows the medical assistant supervisor to store the user's health record information on the medical blockchain, specifically:

[0038] (2-1) Blockchain network nodes use the SHA256 hash algorithm to extract the unique identifier of the user’s medical information containing health record information. The smart contract module encrypts the medical information and stores it in the data storage module.

[0039] (2-2) The smart contract module returns the unique identifier of the encrypted medical information and the encrypted storage location to the blockchain network node;

[0040] (2-3) The blockchain network node packages the unique identifier and encrypted storage location and sends it to the blockchain consensus node; the blockchain consensus node performs consensus processing, puts it on the chain, and sends the hash value of the successful on-chain to the Redis module; the Redis module collects the medical information containing health record information stored in the data storage module and sends it to the data exchange module for storage.

[0041] (2-4) The medical assistant monitoring terminal calls and browses the medical information containing health record information of the corresponding user in the data exchange module.

[0042] Step (2-2) specifically includes:

[0043] (3-1) The smart contract module uses the user's private key to encrypt and sign the extracted unique identifier, which is used to bind the user's identity with medical information; and uses the AES algorithm to encrypt the medical information itself, and saves the user's encrypted signature information and the AES-encrypted medical information to the data storage module for double-layer verification protection; the data storage module establishes a health record information table corresponding to the medical information;

[0044] (3-2) The smart contract module encrypts the storage location using the system key to obtain the storage location of the corresponding user's medical information after encryption.

[0045] Steps (2-3) are specifically as follows:

[0046] (4-1) The blockchain network node obtains the storage location of the encrypted medical information from the smart contract module, and packages the unique identifier of the medical information and the storage location of the medical information encrypted with the system key, and sends them to the blockchain consensus node.

[0047] (4-2) The blockchain consensus node collects the unique identifier of the medical information in the blockchain network node and the storage location of the medical information after being encrypted with the system key. It performs consensus processing to verify whether the hash value generated by each node is correct in order to prevent fake nodes from forging data. After the consensus processing, it will automatically perform the on-chain action and send the hash value generated by this transaction to the Redis module.

[0048] (4-3) The Redis module will send the hash value obtained from the blockchain consensus node to the health record information table corresponding to the user's medical information in the data exchange module for storage, which will be used for traceability in the medical blockchain network system.

[0049] The present invention has the following beneficial effects and advantages:

[0050] 1. This invention, through the key population marking function, helps doctors to formulate targeted treatment and adjunctive treatment strategies in real time based on the physical condition of patients with chronic diseases.

[0051] 2. This invention can effectively reduce the probability of complications in patients with chronic diseases, and is beneficial to the recovery of patients' health.

[0052] 3. This invention can effectively prevent the occurrence of complications in patients with chronic diseases that lead to delayed rescue.

[0053] 4. Based on the inherent structural characteristics of blockchain, this invention ensures that transactions already on the chain cannot be tampered with, and the timestamp attribute will sort them according to the transaction order, protecting users' medical information from unauthorized access and tampering.
