"Shouldn’t Medical manufactures have licence (issued by MHRA) to sell the products? If I have to register to be known as a clinical technologist, manufactures register new equipment before it can be called medical equipment."
They have, it's called a CE mark!!!!
As mentioned throughout this thread, the CE mark denotes that the item meets the required standards for selling & marketing the product within the European Community. In other words, it reaches a certain standard of QUALITY.
As mentioned by Robert, it does not guarantee the safety of the product in use.
