On the assembly line, every medical device is thoroughly checked for quality and functionality. Are all the parts present? Is the needle sharp? Does the device leak? Does air flow where, when and how it’s supposed to? Do triggers and control knobs function correctly? Does the touch screen work?
Even before a medical device gets to mass-production, it must undergo a slew of tests for safety and efficacy. Does the device do what was intended? Are its components and materials inherently safe?
