Description

FIELD OF THE INVENTION

The present invention relates to a field of supply chain management systems. In particular, the present invention relates to a blockchain-based medication logistics system.

BACKGROUND OF THE INVENTION

Supply Chain Management (SCM) is the efficient storage of data on a central or decentralized platform for traceability and effective control of products. Its aim is to improve proper coordination between different entities in the supply chain. It is hard to imagine a world without supply chains. Because it follows a set of guidelines for increasing standardization. Instead of implementing supply chain management in the pharmaceutical industry using databases and clouds, blockchain technology can be used efficiently. A decentralized network has all access instead of a central authority. This ensures safety and robustness. Decentralization is an important factor that provides security on two levels. Blockchain also provides transparency to customers and the information obtained is accurate when tracking products. It creates immutable records of all transactions, making it possible to track assets from manufacturing to delivery. Therefore, blockchain is crucial in the pharmaceutical industry, where speed, coordination and transparency are crucial for the delivery of products. In addition to the above features, blockchain in the pharmaceutical supply chain can reduce theft issues and also manage inventory.

Today, real-time tracking of products such as medicines using traditional methods such as database management systems and cloud-based storage lacks trust and security. It relies on centralization and therefore poses a risk to data confidentiality. Anyone in the supply chain can manipulate the data and incorrect information about the product gets to the customer. That is, such a centralized system cannot prevent the mutability of data. It is also less transparent. Furthermore, the pharmacists tamper with the packaging and information such as MRP and expiry date, which directly affects the consumers and could also harm them. Therefore, it is necessary to create a system to keep track of the medicines, verify the authenticity of the medicines and ensure that the packaging is not tampered with. Use Enter to start a new paragraph. The appropriate spacing and indentation is automatically applied.

When purchasing medicines, pharmacists usually sell the medicines at higher prices by manipulating both the actual RRP and the expiry date. They also become a source of drug addiction by selling prescription drugs to users who have not been prescribed that drug just to make more profit.

Various conventional logistics systems have been disclosed in the past which had several identified deficiencies and issues:-

CN104899466B discloses a kind of drug logistics system and dispenser based on remote diagnosis patterns including client, intelligent platform and electronic trading platform; The customer includes patient side, doctor terminal and pharmacy side; The intelligent platform includes a patient data storage block, an inventory information storage block, a sequence information storage block, an electronic medical record unit and a data analysis module. The present invention realizes the real-time sharing and analysis of data through an intelligent platform, realizes the remote query of real-time monitoring of patient data and from doctor to patient, the patient pays, that is, commercially available medicines by remote confirmation, the hospital pharmacy obtains sequence information Through an intelligent platform organize the drug distribution so that the drug distribution is realized under the remote diagnosis of the entire electronation.

US7232066B2 discloses a drug dispensing unit for tracking medical products that is uniquely associated with a Radio Frequency Identification (RFID) tag. The dispensing unit includes compartments for receiving medical products therein and readers for reading the RFID tags associated with the medical products in the compartments. A processor is coupled to the readers to receive and process the readings from the RFID tags in the compartment to identify the medical products in the compartments. The processor may identify a medical device removed from a compartment by determining a difference between the readings of the RFID tags in the compartment before and after the medical device is removed from the compartment. The processor can check whether the medical device removed from the compartment is authorized for removal, or confirm that an identified patient should receive the medical device removed from the compartment.

TWM610783U discloses a medical care tracking management system comprising a database, an information transmission/reception module, and a management module. The information transmission/reception module is used to receive tag information and a medical supply manufacturing, distribution and usage process, and send the manufacturing, distribution and usage process to a blockchain network and the database. The management module is electrically connected to the information transmission/reception module, and the management module includes a history query module, the history query module obtaining the production, circulation and use process of the medical supplies corresponding to the tag information from the database according to the tags. Information.

All logistics control is centralized and there is complete autonomy, which creates trust issues within the community. The system is not very streamlined and there is no proper infrastructure and system to track prescription drugs. The system requires doctors to write handwritten prescriptions that are very difficult to read and often misunderstood. Also, the pharmacists usually replace the MRP and expiry date with their own, which is highly unfair practice, saying that they have to generate QR or barcodes for their own systems. This poses health risks as well as unfair marketing to consumers. All transactions taking place are not transparent enough and are hidden in the backend with the controllers of the system itself.

Therefore, to overcome the above-mentioned limitations, there is a need to develop a more robust anti-drug addiction infrastructure for the society and create a transparent system regarding MRP and expiry dates of the drugs through blockchain.

The technical advances disclosed by the present invention overcome the limitations and disadvantages of existing and conventional systems and methods.
