MEDICAL DEVICES TESTING:
Welcome to Medical Devices Testing as per MDR 2017.
The Medical Devices Rules 2017 in India were implemented to regulate the import,
manufacture, distribution, and sale of medical devices in the country. These rules are
intended to ensure the safety and efficacy of medical devices and to protect the health of
patients.
The rules establish a regulatory framework for the classification, registration, and testing
of medical devices, and they also provide for the establishment of a central licensing and
registration system for medical device manufacturers and importers.
Additionally, the rules require that medical devices be labelled with specific information
and that they meet certain quality standards. Overall, the Medical Devices Rules 2017 aim
to ensure the availability of safe and effective medical devices in India.
Medical devices are classified into four classes as per the Medical Device Regulation
(MDR) 2017:
- Class I: Low risk devices, such as elastic bandages, that are subject to general safety and
performance requirements.
- Class II(a): Devices that present a slightly higher risk than Class I devices, such as powered
wheelchairs, and are subject to additional safety and performance requirements.
- Class II(b): Devices that present a higher risk than Class IIa devices, such as x-ray machines,
and are subject to additional safety and performance requirements, as well as regulatory
oversight by a notified body.
- Class III: Devices that present the highest risk, such as implantable pacemakers, and are
subject to the most stringent safety and performance requirements, as well as regulatory
oversight by a notified body.
- Class IV: Devices that present the highest risk and are subject to the most stringent safety
and performance requirements, as well as regulatory oversight by a notified body.
All Medical Device must be CE Marked before it can be placed in the European market.
ISO (International Organization for Standardization) sets standards for medical devices
that help ensure their safety and performance. The specific testing parameters for a
medical device will depend on its classification and intended use, but some common
testing parameters for medical devices as per ISO regulations include:
- Biocompatibility: Testing to ensure that a device does not cause an adverse
reaction when in contact with body tissue or fluids.
- Sterilization: Testing to ensure that a device can withstand the sterilization process
without compromising its function or safety.
- Electrical safety: Testing to ensure that a device does not pose a risk of electric
shock or fire.
- Mechanical safety: Testing to ensure that a device can withstand the forces and
loads that it will be subjected to during normal use.
- Performance: Testing to ensure that a device performs as intended and meets its
specified requirements.
- Software validation: Testing to ensure that the software used in a device is safe
and functions correctly.
- Packaging: Testing to ensure that a device is properly packaged and protected
during shipping and storage.
- Environmental: Testing to ensure that a device can withstand the environmental
conditions in which it will be used.
- Labelling and instructions for use: Testing to ensure that the device is properly
labelled and that the instructions for use are clear, accurate and easy to
understand.
- Clinical evaluation: Testing to ensure that the device is safe and effective for its
intended use by evaluating the device's performance in real-world use.
The International Organization for Standardization (ISO) sets standards for medical
devices that help ensure their safety and performance. Some of the ISO standards related
to medical device testing include:
- ISO 10993-1:2018 "Biological evaluation of medical devices - Part 1: Evaluation and
testing within a risk management process" provides guidance on the selection of
tests and the interpretation of results for the biological evaluation of medical
devices.
- ISO 14155:2011 "Clinical investigation of medical devices for human subjects -
Good clinical practice" sets guidelines for the conduct of clinical investigations of
medical devices.
- ISO 14971:2019 "Medical devices - Application of risk management to medical
devices" provides guidelines for the application of risk management to the
development, production, and post-market surveillance of medical devices.
- ISO 15223-1:2016 "Medical devices - Symbols to be used with medical device
labels, labelling and information to be supplied" sets guidelines for the symbols
that should be used on medical device labels and packaging.
- ISO 15223-3:2019 "Medical devices - Symbols - Part 3: Designation of single-use
devices" sets guidelines for the symbols that should be used to indicate that a
medical device is intended for single use.
- ISO 18113-1:2017 "Medical devices - Identification of in vitro diagnostic medical
devices - Part 1: General requirements" sets guidelines for the identification of in
vitro diagnostic medical devices.
- ISO 14644-1:2015 "Cleanrooms and associated controlled environments - Part 1:
Classification of air cleanliness" provides guidelines for the classification of air
cleanliness in cleanrooms and other controlled environments.
These standards provide the guidelines for the testing of the medical devices to ensure
their safety and performance. The manufacturer must comply with the requirements of
the standard before CE marking the device and placing it in the European market.
