introduction
Chemical characterization of medical devices generally includes determining the composition of the product (such as product structure, ingredients, physical and chemical properties, etc.), extraction research,
Extractable study, leachable study, etc. Leachable study is an important part of chemical characterization of medical devices.
Leachables refer to substances released by medical devices or materials during clinical use, generally including
Residual agents, process residues, degradation products, monomers and additives in materials (including stabilizers, antioxidants, plasticizers, colorants, etc.)
According to the different research systems of leachables, they can be divided into known leachables (target leachables) identified based on relevant information and leachables identified based on
Unknown leachable studies can be performed to identify potential known leachables and can also be used to support biological evaluations.
The need for conducting research on unknown leachable substances should be comprehensively assessed for the risks of clinical use of infusion sets.
The general requirement to conduct unknown leachables studies when conducting compatibility studies between liquid devices and drugs does not mean that conducting unknown leachables studies is necessary.
Need process.
The study of unknown leachables generally needs to consider organic and inorganic substances, among which organic substances are qualitatively divided into three categories according to their volatility. volatile
Volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs) and non-volatile organic compounds (NVOCs).
Although a variety of techniques can be used to detect organic leachables, the analytical techniques used to screen for the three types of organic leachables mentioned above are different. Analysis of unknown leachables
The method is different from the known substance research. The selected unknown substance analysis system should refer to GB/T 16886.18-2022 for appropriate methodology.
verify.
YY/T 1550 "Guidelines for Compatibility Studies between Disposable Infusion Sets and Drugs" is planned to consist of three parts.
--- Part 1.Drug adsorption study. The purpose is to establish the drug adsorption under simulated clinical infusion conditions or clinical infusion conditions, single use
Research methods for drug adsorption during contact between infusion devices and drugs.
--- Part 2.Leachable substances. The purpose is to establish the conditions under which a single infusion of a liquid can be prepared.
Study method for the known substances in leachable materials during the contact between infusion sets and drugs.
--- Part 3.Leachable unknowns. The purpose is to establish the unknowns of a single infusion under simulated clinical infusion conditions or under clinical infusion conditions.
A study method for unknown substances in leachable materials during the contact between infusion sets and drugs.
Study on the compatibility of disposable infusion equipment with drugs
Guidelines Part 3.Leachables Study Unknowns
1 Scope
This document describes the process of single-use infusion sets in contact with drugs under simulated clinical infusion conditions or clinical infusion conditions.
Methods for the investigation of unknowns in leachables.
This document applies to specific infusion sets that require studies of unknown leachables and, when necessary, alternative solvents or proposed solutions for the drug that have been demonstrated.
For drugs to be infused, unknown leachable substances should be studied. Other infusion devices can be used for reference if evaluation is required.
