In recent years, the IVD industry has developed rapidly based on the increasing market demand, and plays an important role in disease prevention, clinical diagnosis, health monitoring and guiding treatment. Therefore, followed quality and safety issues are highly concerned. The unique advantages of blockchain technology, decentralization, distrust and non-tampering, can write into trusted node data in every link covering production, circulation and usage of IVD reagents, and establish a distributed ledger with full backup, which makes the anti-conterfeiting and traceability for IVD reagents possible. We discuss whole process intelligent tracing system for IVD reagents based on blockchain technology. Through the strong mechanism of pre-supervision and post-punishment, the source of reagents can be traced, quality and responsibility can be investigated, and the medical inspection quality and diagnostic safety can be guarded.

On October 21, 2021, the National Medical Products Administration issued and implemented the Self-examination Management Regulations for Medical Device Registration. The regulations clarify the specific requirements of the registration applicants in the process of self-examination, and put forward detailed requirements from the aspects of self-examination ability, self-examination report, declaration materials and responsibility requirements, so as to ensure the orderly development of the self-examination of medical device registration. Based on the actual verification work of in vitro diagnostic reagent, this study briefly discussed the understanding of the relevant contents of the regulations, aiming to provide some reference for enterprises and related supervision departments that have the requirement of registered self-examination.

OBJECTIVE: To improve the monitoring mode of diagnostic medical devices adverse events. METHODS: By discussing the objective laws of the characteristics, performances and causes of diagnostic medical devices adverse events, the key points of monitoring work were clarified. RESULTS: The whole-process cloud monitoring mode for adverse events of diagnostic medical devices was constructed based on risk management, and the working procedures for the four core links i.e. collection and report, investigation, analysis and evaluation, and controlling were formulated. CONCLUSIONS The whole-process cloud monitoring mode contributes to improve the monitoring level and efficiency of diagnostic medical devices adverse events in China, so as to strengthen risk control capability and ensure the public can use medical devices safely.

As an important part of medical devices, in vitro diagnostic reagents are important means to prevent and diagnose and protect people's health. Supervision and sampling is an important and key supervision method to ensure the in vitro diagnostic reagent products are qualified. This paper summarizes the problems encountered in recent years in vitro diagnostic quantitative testing kit supervision sampling, analyzes the causes of these problems, and puts forward corresponding suggestions, hoping to provide constructive suggestions for supervision sampling.

Clinical trial is an important step of in vitro diagnostic reagents research and development. Based on the Guiding Principles and the key points of inspect on the spot, combined with the actual work experience, the article focuses on the prominent problems in the whole process of in vitro diagnostic reagent clinical trials. It is helpful to improve the level of hospital drug clinical trial centre and the quality of in vitro diagnostic reagent clinical trials by analyzing the issues.
