ABSTRACT:
A suction connector, comprising a fluid passage (31) having one end to be connected to a conduit and the other end to be connected to a suction source when in use and a ventilating passage (32) branched in the middle of the fluid passage and having an opening end (33), wherein a blocking plate (34) is disposed at least at a partial region on a fluid passage side inside the ventilating passage, the cross-section of the ventilating passage is divided by the blocking plate into a plurality of regions, and fluid advancing from the fluid passage into the ventilating passage is prevented by the blocking plate from flowing out from the opening end, whereby a sucking force caused by an releasing a negative pressure can be regulated sufficiently, spattering of fluid can be surely prevented to thus eliminate the danger of contamination and infection to an operator and assuring sanitation, and a structure is simplified.
