What does single-use medical device include? What is the definition of single-use medical devices?

There are too many single-use medical devices, such as syringes, infusion sets, cotton balls, cotton swabs, gauze blocks, steel nails, sterile, non-sterile, implantable, interventional, sanitary materials, equipment, etc. If you list them, I'm afraid that at least a few thousand words, the whole page can not be typed. Only a use that is scrapped, can not be reused medical devices are disposable medical devices.
