A medical device (1) is in the form of a flexible tube (1) having a first end (2) and a second end (3) each adapted for insertion at separate points through the skin (4) of a body into a blood vessel (5), such that the tube (1) defines a conduit that traverses at least in part above the skin (4) of the body. In use, blood flow is diverted from the body through the tube (1) and back to the body. The fluid flowing through the tube (1) above the skin is available for continuous analysis, for example, by a Raman spectroscopy system (10) that analyses the blood for glucose concentration.
