Probe

摘要

A probe, such as a spectroscopic probe, for enabling a fluid or tissue sample to be tested in situ. The probe includes a conduit, such as a hypodermic needle, that can be inserted into a test subject and a wave coupling arranged to direct electromagnetic radiation, such as light, from an energy source to the sample and/or from the sample to a receiver for analysis. The receiver may comprise a Raman spectroscope. The probe may include a carriage that can be used to move at least some of the optical coupling towards and away from the insertion tip of the conduit. The probe may include a pressure modifier that can be used to draw fluid into or expel fluid from the conduit.
