Medical equipment purchasing management system and method based on block chain

Abstract

The invention relates to a medical equipment purchase management system and method based on a block chain, and the system comprises: a data collection layer which is used for collecting purchase information, wherein the purchase information comprises a budget file, a demand file, and an actual purchase file; a purchase management layer which is used for performing block processing on the collected purchase information to obtain a pre-purchase information data block, a purchase information data block and a post-purchase information data block; and a data application layer which is used for querying the information data of the purchase management layer, wherein a query path comprises auditing department information query, superior department information query and past information backtracking query. According to the method, the block chain is utilized to store the purchase information of each link, and the block chain has the characteristics of unforgeability and non-tampering, so that the block distributed storage can be carried out on the medical equipment purchase full-cycle links from budget to demand to purchase, use and other full-cycle links of all medical equipment purchase,.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to a block chain-based medical equipment procurement management system and method. Background technique [0002] Under the modern medical system, medical technology is increasingly inseparable from medical equipment. From prevention, diagnosis to treatment and rehabilitation, medical equipment plays a huge role. With the development of my country's medical industry, the annual purchase of medical equipment is huge. The amplitude is normal, and the research, development, and replacement of medical equipment are also constantly developing. [0003] Blockchain (Block Chain) is a non-forgeable and non-tamperable blockchain that uses cryptography to ensure transmission and access security, and is jointly maintained by multiple parties using computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms.

Problems solved by technology

[0004] However, the risk of medical equipment procurement has always been prominent, and it is a key area of ​​audit and supervision. However, the past procurement process is to keep paper copies, which are easy to lose and tamper with records. Existing units use electronic means, but there are also tampered databases. and other loopholes, resulting in difficulties in backtracking and audit supervision
