What Is Medical Devices Testing?


Medical device testing includes an end-to-end analysis, assessment, and evaluation of any medical device to certify that it performs as intended, does not provide faulty information, and is fit for practical usage. A properly tested medical device also meets the required federal and regulatory criteria.

How are new medical devices tested?

Medical devices must undergo rigorous electronic testing in order to meet the highest quality standards. Most of the class II and III medical devices have microprocessors at their core. Hence, microprocessor evaluation is the first step in medical device testing.

What is biocompatibility testing for medical devices?

An integral part of biological risk assessment, biocompatibility testing assesses the compatibility of medical devices with a biological system. It studies the interaction between the device and the various types of living tissues and cells that are exposed to the device when it comes into contact with patients.

What is included in medical devices?

Medical devices range from simple tongue depressors and bedpans to complex programmable pacemakers, and closed loop artificial pancreas systems. Additionally, medical devices include in vitro diagnostic (IVD) products, such as reagents, test kits, and blood glucose meters.

What is the function of testing device?

Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipment is essential to any serious work on electronics systems.

What is bench testing medical devices?

Bench testing — a crucial step in the early device design process — is designed to tease out mechanical and design flaws in devices, and to test endurance of the device in the human body without having to implant the device in a human.

How do you test a medical device software?

A testing process for software for medical devices of all levels of concern should comprise the following activities:

  1. Software validation.
  2. Software requirements verification.
  3. Software design verification.
  4. Code reviews and unit testing.
  5. Software verification.
  6. Compliance verification.
  7. Thorough and complete test documentation.

Do Class 1 medical devices need a 510k?

Most Class I devices are exempt from Premarket Notification 510 (k); most Class II devices require Premarket Notification 510(k); and most Class III devices require Premarket Approval.


What is type testing in China?

Essentially a testing of a product sample against a technical standard (the Product Technical Requirement) which is usually based on a national product standard in China. Type testing adds 3-6 months to the product approval process and is a prerequisite to obtaining a clinical trial approval in China.

What are biocompatibility tests?

Biocompatibility testing is a critical part of the regulatory approval process for medical devices as even the best designed products can produce unintended complications if the materials used cause a biological reaction in the patient.

How is biocompatibility determined?

Uveal biocompatibility refers to how well an IOL is tolerated inside the eye without causing deleterious changes and immunogenic responses. Other ways of defining biocompatibility include capsular biocompatibility, which is determined by the direct contact with the lens capsular bag and remnant lens epithelial cells.

What is biological testing?

Definition. Biological test methods describe standardized experiments that determine the toxicity of a substance or material by evaluating its effect on living organisms. Tests are designed to use appropriate organisms and sensitive effect measurements in the media of interest for a specified test duration.

Is a toothbrush a medical device?

The device class will be displayed as 1, 2, or 3. In this example, a manual toothbrush is a class 1 medical device. A manual toothbrush is 510(k) exempt, meaning it does not require premarket notification or approval.

What is an example of a medical device?

For example, a syringe is a medical device. “Certain radiation-emitting electronic products that have a medical use or make medical claims are also considered medical devices. Examples of these include diagnostic ultrasound products, x-ray machines and medical lasers.”

What is a Class 2 medical device?

Class II medical devices are those devices that have a moderate to high risk to the patient and/or user. 43% of medical devices fall under this category. Most medical devices are considered Class II devices. Examples of Class II devices include powered wheelchairs and some pregnancy test kits.
