A guiding and positioning device for guiding and positioning a bore needle into a specific position within a vein of a patient or person comprises a first body defining a proximal end and a distal end and including a first needle extending from the distal end and establishing fluid communication through the first body from the distal end to the proximal end. The device furthermore comprises a second body for co-axially supporting and receiving the bore needle having an aperture at its distal end, the aperture defining a specific angle relative to the longitudinal axis of the bore needle, the second body and the bore needle including positioning means. In the device, a web body is provided defining opposite first and second sides, the first body being mounted to the web body at the first side and the second body being mounted to the web body at the second side, respectively, the web body defining an angle between the first needle and the bore needle when received in the second body for positioning the aperture of the bore needle in the specific position in alignment with the first needle and opening substantially in the longitudinal direction of the first needle. The positioning means serve to rotationally orientate the bore needle in the specific position. <IMAGE>
