Medical equipment use data management method and system based on block chain

The invention relates to a block chain-based medical equipment use data management method and system, and the method comprises the steps: obtaining finger vein image information based on a preset finger vein collection device, and generating a medical equipment starting instruction, acquiring actual use state data of the current medical equipment in a past preset time period from a preset block chain storage module, acquiring current actual state data of the current medical equipment at the same time, respectively generating data change broken line diagrams, importing a current equipment state score into a preset equipment state evaluation model, and evaluating the state of the current medical equipment according to the data change broken line diagrams. And obtaining a current state evaluation result output by the equipment state evaluation model, generating a medical equipment function starting instruction, and storing the current actual state data and the current state evaluation result in the block chain s
