基于区块链技术的医疗设备采购管理系统的设计与实现

Design and Implementation of Medical Equipment Procurement Management System Based on Blockchain Technology

目的针对传统采购资料易丢失和被篡改,无法保证采购数据安全性的问题,设计一套基于区块链技术的医疗设备采购管理系统。方法系统采用Python编程语言设计,使用Django框架、SQLite数据库,基于区块链技术构建区块链服务器、采购人客户端、采购机构客户端、供应商客户端、监管机构客户端,将整个采购过程中的数据全部进行区块化处理,使得所有数据保存完整,不能被随意窜改,最终实现具有防篡改特性并支持溯源的医疗设备采购管理系统。结果该系统各模块以及防篡改机制均通过测试验证;各模块的平均响应时间均<2 s,响应速度快;模拟网络及身份验证安全测试的结果显示,其安全性能均满足要求。结论将区块链技术应用于医疗设备采购管理系统是可行的方案,其保证了整个采购流程中产生的数据完整可靠并防止被篡改,使得采购信息能够在系统中完整留痕,从而对医疗设备的采购进行全方位管理。

Objective Aiming at the problem that traditional procurement data is vulnerable to loss and tampering,and the security of procurement data cannot be guaranteed,to design a medical equipment procurement management system based on blockchain technology.Methods The system was designed by using the Python programming language with the Django framework and SQLite database.It utilized blockchain technology to build a blockchain server,as well as purchaser client,procurement agency client,supplier client and regulatory agency client.The entire purchasing process data was blockified,ensuring that all data was stored intact and cannot be tampered arbitrarily.Ultimately,it achieved anti-tampering features and supported traceability in the medical equipment procurement management system.Results All modules of the system and the anti-tampering mechanism have been verified.The average response time of each module was less than 2 s,indicating a fast response speed.The results of simulated network and authentication security tests showed that its security performance met the requirements.Conclusion Applying blockchain technology to the medical equipment procurement management system is a feasible solution.It ensures the integrity and reliability of the data generated throughout the procurement process and prevented tampering.This allows for complete traceability of procurement information within the system,enables comprehensive management of medical equipment procurement.
