Electronic medical record system based on block chain

Abstract

The invention discloses an electronic medical record system based on a block chain. The electronic medical record system comprises a case write-in module for writing in patient cases, the case write-in module is in output connection with a temporary storage module for temporarily processing storage data, and the temporary storage module is in output connection with a block chain write-in module for generating and calculating block hash values; the block chain write-in module is in output connection with a block chain server for storing block chain contents; the block chain server is connectedwith a hospital block chain server of another hospital for storing block chain contents, and the block chain server and the hospital block chain server are both connected with a cloud for storing theblock chain contents in a wireless and / or wired manner; and the cloud is wirelessly connected with an operation end which is connected with the case write-in module. According to the method, the trouble of case loss is reduced, doctors can know patient information conveniently, the doctors can judge the patient information accurately and conveniently, data damage can be effectively prevented, anddata integrity is guaranteed.

Description

technical field [0001] The invention relates to the technical field of blockchain electronic medical records, in particular to a blockchain-based electronic medical record system. Background technique [0002] The patient's electronic medical record is very important when visiting the doctor. It is an important basis for the doctor to judge the condition in the next visit, and has an important impact on the accuracy of the doctor's judgment. Traditional electronic medical records are also based on paper cases or discharge summaries. The method is stored on paper, and the patient will show the case and other relevant documents to assist the doctor in judging the situation the next time he sees a doctor. However, paper documents are difficult to save and patients are difficult to carry. Although hospitals also have electronic medical records, there is a gap between hospitals. The electronic medical record files are not connected to each other, and the files are difficult to sh...

[0002] The patient's electronic medical record is very important when visiting the doctor. It is an important basis for the doctor to judge the condition in the next visit, and has an important impact on the accuracy of the doctor's judgment. Traditional electronic medical records are also based on paper cases or discharge summaries. The method is stored on paper, and the patient will show the case and other relevant documents to assist the doctor in judging the situation the next time he sees a doctor. However, paper documents are difficult to save and patients are difficult to carry. Although hospitals also have electronic medical records, there is a gap between hospitals. The electronic medical record files are not connected to each other, and the files are difficult to share. When the data files are damaged, it will cause irreparable data loss. Due to the closed nature of the system, the credibility of the electronic medical record information is low, and it may be tampered with later. Reliability is difficult to measure, and most of the evaluation data is stored in a fixed server. Once the data server is damaged, data loss may occur, resulting in irreparable data loss
