At its most general, the present invention proposes a priming device and method for priming a multi-conduit fluid connector device of a percutaneous fluid access apparatus or subcutaneous fluid access apparatus, in which device and method multiple fluid channels are each arranged to connect to a respective conduit of the multi-conduit fluid connector device to permit deliver of priming liquid from each conduit to a respective fluid channel, and an indicator associated with each respective fluid channel is arranged to indicate the presence of priming fluid within that fluid channel. The priming device of the present invention provides a solution to the problems of known priming methods. The indicators of the multiple fluid channels ensure that it is possible to readily detect when each of the conduits of the multi-conduit fluid connector device has been correctly primed such that any air is expelled. Further, this ready detection ensures that the clinician/user does not have to observe the priming process at a close distance, so reducing the possibility of contamination. Furthermore, it is not necessary for the conduits of the multi-conduit fluid connector device to be exposed during the priming process, so further reducing the contamination risk.
