Description

Technical Field

[0001] The present invention relates to the technical field of blockchain nodes, and specifically to a blockchain data storage method and a blockchain node system. Background Art

[0002] Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is a distributed ledger that is cryptographically guaranteed to be tamper-proof, unforgeable, fully traceable, and decentralized.

[0003] With the development of blockchain technology, in the field of domestic medical technology, the medical technology level in developed areas is generally higher than that in remote and poor areas such as underdeveloped areas. Therefore, when patients in areas with relatively low medical technology levels encounter difficult-to-solve conditions, they often cannot get targeted treatment and corresponding medical data, and often face transfers to other hospitals, which is not only time-consuming and labor-intensive, but also affects the optimal treatment time and seriously endangers life safety. Therefore, it is very necessary to design a blockchain data storage method and blockchain node system that is highly practical and can be used for centralized treatment in hospitals for similar conditions. Summary of the invention

[0004] The purpose of the present invention is to provide a blockchain data storage method and a blockchain node system to solve the problems raised in the above background technology.

[0006] According to the above technical solution, the patient blockchain data packaging module includes a symptom data storage module, a test report data storage module, a disease diagnosis data storage module and a digital signature verification module. The symptom data storage module is used to record and store the disease symptoms reported by the doctor when the patient is treated in the hospital. The test report data storage module is used to further perform physical test report data obtained by medical equipment testing when the doctor diagnoses the patient's disease symptoms, and record and store the test report data. The disease diagnosis data storage module is used to record and store the diagnosis result data and treatment plan data after the doctor diagnoses the patient's disease symptoms. The digital signature verification module is connected to the symptom data storage module, the test report data storage module and the disease diagnosis data storage module. The digital signature verification module is used to package the patient's symptom treatment data into blocks for storage, and perform digital signature verification to prevent data tampering and improve the security of data storage.

[0007] According to the above technical solution, the blockchain central node module includes a patient blockchain extraction module, a keyword locking module, a condition similarity calculation module and a blockchain node establishment module. The patient blockchain extraction module is used to extract all patient symptom treatment data blocks in the blockchain service network. The keyword locking module is used to lock the data keywords in each patient symptom treatment data block. The condition similarity calculation module is used to calculate the similarity between the condition of different patients and the personal condition. The blockchain node establishment module is used to establish a blockchain node with the current personal condition data as the blockchain node, and connect the blocks packaged by patients whose similarity meets the personal condition data to the established blockchain node.

[0008] According to the above technical solution, the disease condition similarity calculation module includes a radar image establishment submodule and an overlap comparison submodule. The radar image establishment submodule is used to establish a radar chart for keywords extracted from different patient symptom treatment data blocks, and the overlap comparison submodule is used to compare the radar dimension chart of personal disease condition symptom data with the radar dimension chart of other patients' disease condition symptom data in the blockchain service network, so as to obtain the disease condition similarity according to the overlap rate of the radar image area.

[0009] According to the above technical scheme, the condition communication module includes a node sub-center communication module and a node center main communication module. The node sub-center communication module is used to conduct partial rights communication on the condition of patients whose condition symptom data at the established blockchain node sub-center is relatively similar to the personal condition symptom data. The node center main communication module is used to conduct full rights condition communication on patients whose condition is very similar to the personal condition.

[0010] A blockchain data storage method, the blockchain data storage method mainly comprising the following steps:

[0011] Step S1: When an individual goes to the hospital for diagnosis and treatment, he / she explains his / her physical symptoms to the doctor and after receiving treatment from the hospital, the patient blockchain data packaging module stores the individual's current diagnosed symptoms, test reports, diagnosis results, and treatment plan data;

[0012] Step S2: The digital signature verification module packages the patient's symptom treatment data into blocks and stores them in the blockchain service network, and performs digital signature verification to prevent data tampering and improve the security of data storage;

[0013] Step S3: The patient blockchain extraction module extracts the blocks in the blockchain service network and decompresses the block storage data;

[0014] Step S4: The keyword locking module performs keyword locking and data sorting on the disease data stored in the numerous blocks;

[0015] Step S5: With the personal medical condition data as the center, the medical condition similarity calculation module calculates the similarity between the medical condition block data in the blockchain service network and the personal medical condition data;

[0016] Step S6: Establishing a blockchain node with the personal medical condition data as the center in the blockchain service network, and arranging the chain lengths of blocks and personal blockchain nodes with different similarities in the blockchain service network;

[0017] Step S7: Taking the blockchain node established by the individual as the center, different radius lengths are drawn to form the node sub-center communication module area and the node center main communication module area, and different rights are granted for medical condition communication.

[0018] According to the above technical solution, step S4 further includes:

[0019] Step S41: locking keywords of the location, condition, time and whether there is a major medical history of the patient's symptoms;

[0020] Step S42: Retrieve medical examination report data, and lock abnormal data in the medical examination report data as keywords;

[0021] Step S43: extracting keywords of doctor's diagnosis results and treatment plans.

[0022] According to the above technical solution, step S5 further includes:

[0023] Step S51: Establishing a plane rectangular coordinate system, establishing a radar chart with the origin of the plane rectangular coordinate system as the center, and the radar image establishment submodule simulates a triangular radar chart with keywords extracted from different patient symptom treatment data blocks;

[0024] Step S52: The three corners of the triangular radar chart respectively correspond to the symptom data keywords, report data keywords, and treatment data keywords extracted by the three major keyword extraction modules. Each corner of the triangle corresponds to a pointing area of 120 degrees. Each degree deviation in the activity range represents a different keyword. The closer the meanings of different keywords are, the smaller the deviation of the corresponding triangle corner. At the same time, the distance from each corner vertex of the triangular radar chart to the origin of the plane rectangular coordinate system represents the severity index of the disease data;

[0025] Step S53: The coincidence degree comparison sub-module compares the radar dimension chart of the individual's disease symptoms data with the radar dimension charts of the disease symptoms data of other patients in the blockchain service network to obtain the coincidence area S 重 , the area S 个 of the individual's triangular radar chart and the area S 比 of the comparison target triangular radar;

[0026] Step S54: The similarity formula for calculating the disease block data in the blockchain service network and the individual's disease data is: In the formula, T is the similarity value between one of the disease block data in the blockchain service network and the individual's disease data. When the value of T is closer to 100%, it indicates that the similarity between this disease block data in the blockchain service network and the individual's disease data is higher.

[0027] According to the above technical solution, in step S6, in the blockchain service network, each person can establish a blockchain node centered on their own disease data. The similarity T value between each disease block data in the blockchain service network and the individual's disease data can be converted into the chain length of the individual blockchain node. The larger the T value, the shorter the corresponding chain length, and the closer to the individual blockchain node. On the contrary, the smaller the T value, the longer the corresponding chain length, and the farther from the individual blockchain node.

[0028] According to the above technical solution, step S7 further includes:

[0029] Step S71: The area where 80% < T ≤ 90% is designated as the node sub-center communication module area. Patients in the node sub-center communication module area can communicate with the individual for rehabilitation conditioning and can view the rehabilitation conditioning data stored in the corresponding blocks of the patients in the area to help the individual continue to recover after hospital treatment;

[0030] Step S72: The area where 90% < T ≤ 100% is designated as the node center main communication module area. Patients in the node center main communication module area can communicate with the individual for a complete treatment plan and can view all the treatment data stored in the corresponding blocks of the patients in the area to achieve decentralized treatment without going to the hospital.

[0031] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, by providing a patient blockchain data packaging module, a blockchain central node module and a condition communication module, can enable patients in areas with different medical technology levels to find the block storage data of similar conditions under the blockchain service network after the first medical registration and acceptance of the treatment plan, and establish a central node with personal condition data to obtain treatment plan data of different patients with different similarities, thereby realizing the characteristics of centralized treatment in hospitals and improving the overall medical technology level in backward areas.
