Abstract
A fluid handling device comprises a barrel for containing fluid to be delivered through a needle, a needle-mounting hub at one end of the barrel, a biasing element arranged to urge the hub inwardly of the barrel, a stop element blocking inward movement of the hub into the barrel, and a hollow plunger which is movable within the barrel to deliver fluid from the barrel via the needle and has at its forward end a portion which is severable in response to movement of the plunger over the final part of, or at the conclusion of, its delivery stroke to allow retraction of the needle-mounting hub into the hollow plunger, the hub and the stop element being formed as plastics mouldings in such a way that the stop element is axially captive with the hub and the plunger being arranged to disengage the stop element and the hub during said final part of, or at the conclusion of, the delivery stroke to allow the biasing element to drive the needle into the hollow plunger.
