Abstract:
1. Bodily fluid sampling or transfusion device incorporating protection means, said device including: a longitudinal hollow central body that enables a fluid to flow between a first end and a second end, is provided at its proximal end with means for connecting it to a sampling or transfusion line and is attached to a coaxial needle that projects from its distal end, means for selectively covering the projecting portion of the needle after use, a longitudinal hollow external body that has a peripheral tubular wall, is attached to the central body, is disposed concentrically around the central body and is conformed to constitute holding means for a user to hold onto, an annular passage between the central body and the external body, a protective tube that can slide longitudinally in the annular passage between the external body and the central body and has a proximal holding end for moving it selectively between, on one hand a proximal retracted position in which the needle is not covered by the protective tube or only very slightly covered thereby so that it can be used to draw a sample or to administer a transfusion, and on the other hand a distal protection position in which the protective tube covers the needle over its entire length, at least one radial fixing bridge attaching the external body to the central body and extending radially from the central body to the external body, and at least one longitudinal slot that extends over at least a portion of the length of the protective tube and in which said at least one radial fixing bridge slides during sliding movement of the protective tube relative to the central body and the external body, wherein: the central body, the radial fixing bridge and the external body are in one piece, and the longitudinal slot extends as far as the distal end of the protective tube.
