Graduated SAFE-T-VAC™ single suction catheter features a chimney-style valve that has a large opening on the control vent that minimizes residual suction. These catheters are not the graduated variety and come in straight packs (not coiled). Available in multiple sizes and sterile Safe-T-Vac catheters are also latex free. Low drag catheter surface makes for easier insertion and a large opening on the control vent provides great suctioning control. Available in a variety of sizes.
