ISO 10993-18 Chemical Characterization Testing of Respiratory Materials
The ISO 10993 series is a set of standards developed by the International Organization for Standardization (ISO) to provide guidance on biocompatibility testing. Among these, ISO 10993-18:2017 specifically addresses chemical characterization tests for materials used in medical devices intended for contact with human tissues or fluids. This particular standard is crucial for the development and regulatory compliance of respiratory and ventilation device components.
The testing under ISO 10993-18 involves a comprehensive evaluation of potential leachable substances from the material, including metals, chemicals, and other additives that could be released into the environment during use. The objective is to ensure that these materials do not pose any significant health risks when used in medical devices such as ventilators, oxygen concentrators, nebulizers, and masks.
The testing protocol outlined in ISO 10993-18 is designed for various types of respiratory materials like plastics, metals, textiles, and composites. These materials are subjected to a range of chemical extraction methods to simulate real-world conditions. The extracted compounds are then analyzed using advanced analytical techniques such as gas chromatography-mass spectrometry (GC-MS), inductively coupled plasma mass spectrometry (ICP-MS), and high-performance liquid chromatography (HPLC).
The testing process is complex and involves multiple stages:
- Material Selection: Identification of the respiratory materials to be tested.
- Extraction Methods: Utilization of solvents such as water, ethanol, acetone, or phosphate buffer saline (PBS) to extract potential leachables from the material.
- Analysis Techniques: Use of sophisticated analytical instruments to identify and quantify the extracted compounds.
- Interpretation: Evaluation of the data to determine if any identified compounds are hazardous or could pose a risk to patients.
The results of these tests provide crucial insights into the safety profile of respiratory materials, ensuring that they meet stringent regulatory requirements and pass rigorous quality checks. This testing is essential for manufacturers aiming to comply with global standards and gain market access in various regions.
Compliance with ISO 10993-18 can significantly reduce the risk of adverse events associated with medical devices and enhance patient safety. It is a critical step in the development process, ensuring that materials used in respiratory devices are safe for clinical use.
| Industry Applications | Description |
