os: This article has a good starting point, but it has little relevance to the blockchain. You can skim it to learn the structure and concept of the article.
1 Introduction
Based on blockchain technology, the author uses the whole life cycle theory to construct a complete set of medical equipment management information system. Realize the full life cycle management of medical equipment, strengthen the standardized management of medical equipment, and achieve the goals of medical equipment safety, traceability, and cost control.
2. Analyze and build models
3. Management system of medical equipment
-
Production management module
Medical institutions should strictly review the qualifications of manufacturers and suppliers during the access process, and will not approve suppliers who have not provided three certificates and one certificate, and will not enter products that are not within the scope of permission.
-
Medical equipment access management module
Medical equipment can be roughly divided into the following categories. Through the centralized review of the Medical Equipment Committee, and access to new medical equipment. At this stage, the data and materials of each link are distributed and stored through blockchain technology to ensure the standardization of the access process and data security.
1. New medical equipment that has not been used by medical institutions
2. Emergency medical equipment that has not been used by medical institutions but is used for clinical emergency rescue or new projects
3. Special medical equipment for newly purchased equipment in clinical departments.
-
Medical Equipment Purchasing Management Module
This module mainly realizes the tracking management of purchase orders and the evaluation management of suppliers.
-
Problems of the medical equipment storage management module
:
1. Traditional manual entry, heavy tasks and error-prone
2. Workers need to set up reasonable inventory reserves for each type of consumables
3. Bad environment or expired cause a lot of waste of medical equipment
4. High-value consumables in and out of the warehouse Complicated, and some consumables need to be determined during the operation, which may easily lead to medical accidents
This module solves the problems found, optimizes the process, subdivides the functions, and finally completes the storage management of medical devices
- Problems of the medical equipment use settlement management module
:
1. In clinical use, the use status and flow direction of medical equipment are missing, and there is no effective control method.
2. The traditional hospital information system is not perfect, and the hospital HIS system is not interconnected with the medical equipment management system and financial
system
. Linkage with HIS system and financial system to promote integrated management of people flow (patient information), logistics (material information) and financial flow (financial information) - Destruction link
- Traceability Management Module
Medical institutions mainly adopt a bottom-up approach, from use to production, from patients-users-operating enterprises-manufacturers. For implantable and interventional high-risk medical devices, the serial number is used as the main traceability and identification key to track each device. For some implantable or interventional medical devices produced in batches, the batch number is also added. A separate serial number so that the combination of serial and batch numbers can be traced.
4. Classified management of medical equipment
-
Stock-based management of high-value consumables
Implement a four-level traceability process of "supplier-secondary library-clinical department-patient". The management principle is zero inventory traceable management to ensure timely supply.
-
Subsequent high-value consumables management
-
Low-value billable material management
-
No separate billing material management
5 Conclusion
The author comprehensively combs the management mode and key links of medical equipment, and optimizes the business process on this basis. The key links of medical equipment management are sorted out, and the supply chain supervision mechanism based on blockchain technology is integrated into various management modes, as well as the full life cycle supply chain management mode based on blockchain.
The author conducts in-depth research on medical equipment, introduces a full life cycle supply chain management model based on blockchain technology, strengthens procurement supervision, establishes a tracking mechanism after warehousing, and traces medical equipment throughout the process.
Personal point of view:
The whole article revolves around the management process of medical equipment and the difficulties in each link. However, it did not elaborate on which aspects of blockchain technology should be started, nor did it design prototypes and conduct actual data tests. The article sorts out the supply chain process of medical equipment in hospitals in detail, and the effective combination with blockchain is still worth exploring.
