Abstract:
PCT No. PCT/DE91/00066 Sec. 371 Date Sep. 16, 1991 Sec. 102(e) Date Sep. 16, 1991 PCT Filed Jan. 22, 1991 PCT Pub. No. WO91/11211 PCT Pub. Date Aug. 8, 1991.A device for infusion or transfusion can be connected to a flexible tube line (16). The regulating arrangement (8, 9, 10, 12) for regulating the flow rate of the fluid through the flexible tube line (16) is a rigid structural member of the intravenous drip chamber (1) containing the infusion or transfusion liquid. The flow rate is regulated by means of a regulating nut (12) which effectively connects the regulating knob (10) with a flexible tube line (16). The structural member has a tubular connection piece (2) provided with a closed end (3) and having lateral perforations (4). The tubular connection piece (2) is coaxially spaced by a surrounding tubular threaded pipe (6) divided into segments (8, 9) separated by dividing points (7). The lateral perforations (4) open into downwardly directed grooves (5) which establish a flow path. The segments (8, 9) are provided with regulating members (10) which move the tube line into the grooves (5) and are displaceable by an internally threaded regulating nut (12) threaded on the threaded pipe (6).
