The proximal ends of lumens 18, 22 open into a Y-shaped connector 12, one branch of which leads lumen 18 to a suction pump, the other branch leading lumen 22 to a bacteria filter 24 having a continuation tube open to the air. The diameters of round apertures 20 are smaller than that of lumen 18 to prevent blockage of the latter when suction is applied by the pump. Filter 24 may be replaced by a medicament for anticoagulant. Lumen 22 opens into lumen 18 between apertures 20 and the end 14. The device is of clear, medical grade silicone rubber, thermoplastics or vulcanisable material and may be extruded and/or moulded.
