ABSTRACT:
It is intended to a probe, an apparatus for parenteral or enteral infusion.
Two bodies (1, 2) are nested one into the other. They comprise each an inner cylindrical flowing means (4, 11) engaged one into the other by one of the ends thereof (4b, 11b) until the respective closing plates thereof (8, 14) are in contact. The outer casings (3, 10) co-operate by the ends thereof (18, 20) so as to keep the two bodies (1, 2) in an engagement relationship. The two bodies (1, 2) rotatingly move one with respect to the other and hence allow to regulate the flow by variable juxtaposition of the half-moon openings (9, 15) arranged in the closing plates (8, 14).
