Blog, EU Regulations, Guides and Advice, Medical Device Pre-launch, Medical Device Validation, Standards, UK Regulations, USA Regulations /

Skin irritation occurs when a substance causes inflammation or damage to the skin upon contact. For medical devices, this can be a serious concern, as they are often in prolonged contact with the skin. The consequences of not adequately testing for irritation can range from minor redness to severe dermatitis, leading to discomfort, injury, or even infection in users. Therefore, reliable testing methods are crucial to ensure that products are safe before they reach the market.

ISO 13485 is an international standard for mapping what is required from a medical device. The system ensures that medical devices are effective and consistent throughout their life cycle, from planning and production to disposal.

Ensuring consistency is extremely important for medical devices, as patient safety could be at risk. Implementing quality management systems can also provide protection for manufacturers and their reputations, as risks can be easily identified and rectified.

Medical device regulation varies based on the classification of the medical device being manufactured. All parties are required to demonstrate compliance, from the medical device manufacturing process to the disposal of the product.
