Introduction

This document provides guidance methods for the determination of 2,2-bis(4-hydroxyphenyl)propane (bisphenol A) residues in medical polycarbonate materials. Medical polycarbonate material is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it is divided into aliphatic, aromatic, and fatty. Aliphatic-aromatic and other types. Aromatic polycarbonate has better mechanical properties than other types of polycarbonate materials and is widely used in medical field. Bisphenol A is one of the synthetic monomers of aromatic polycarbonate materials. Bisphenol A may remain in the polycarbonate production process. Pro When the bed is used, residual bisphenol A in polycarbonate medical devices has the risk of migrating into the patient's body. When bisphenol A is introduced into the human body, it may Causes diseases such as diabetes, cardiovascular and cerebrovascular and reproductive systems, thus affecting the normal functions of the body. Therefore, it is necessary to monitor the double content of medical polycarbonate materials. The residual amount of phenol A is very necessary. 2,2-bis(4-hydroxyphenyl) in medical polycarbonate materials Method for determination of propane (bisphenol A) residue

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 extreme extractionexhaustiveextraction Perform multi-step leaching until the leached substance is measured gravimetrically (or achieved by other methods) in subsequent leaching steps. The amount is less than 10% of the amount measured in the first extraction. [Source. ISO 10993-18.2020,3.15] 3.2 Leaching that is expected to result in the release of greater or greater amounts of chemical constituents than would be expected under clinical use conditions. NOTE. It is important to ensure that intensive leaching does not result in chemical changes in the material or substance being leached. [Source. ISO 10993-18.2020,3.14] 3.3 simulated extraction Extraction using a method that simulates clinical use. NOTE. The purpose of conducting simulated leaching is to estimate the type and amount of substances expected to be released from the medical device during clinical use. Simulated leaching aims to generate a Leachables spectrum, which represents the worst-case leachables spectrum, i.e., all leachables are also leachables, and the levels of all individual leachables At least equal to the level of all individual leachables.
