Grading card, read-write device, and medical care administration system and method

Abstract

The invention discloses a grading card, a read-write device, and a medical care administration system and method. The system comprises the grading card and the read-write device; the grading card comprises a transceiving module; a data storage module for storing the nth data; the read-write device comprises a read-write module for reading-writing identity information of the grading card and the nth data; a calculation module for calculating the nth hash value; a block synthesis module for synthesizing the nth data and the nth hash value into the nth block; a modification module for modifying the nth data and obtaining the n+1th data; a read-write storage module for storing the nth block and the n+1th block; and a writing module for writing the n+1th data into the grading card. According tothe medical care administration system provided by the invention, based on the unidirectionality and collision constraints of a hash function, in a blockchain composed of hash values, block data aresafe, not easy to tamper, and traceable; and in addition, only a n-1th hash value is included in the nth data stored in the grading card, so that the safety is improved.

Description

technical field [0001] The invention relates to the field of medical care management, in particular to a graded card, a read-write device, a medical care management system and a method. Background technique [0002] In mass casualty accidents and disasters, due to the large number of wounded, sick and dead, and chaos on the scene, the efficiency of medical care management for the wounded, sick and dead is low, and data confusion is prone to occur. [0003] In this kind of medical management work, the following technical functions need to be realized: 1. Distinguish the identity of the wounded and the dead; 2. The identity of each wounded or dead has a unique code that is convenient to read, write, and set. Fill in the grading card, read and write the RFID card through the reader at the same time, read the unique code, and enter the information of the wounded and sick; 3. The aforementioned unique code can read and write the patient's condition and treatment situation many ti...
