Trachi-Swab Hi Vis Tracheostomy Tube Cleaning Swab. Trachi-Swab cleaning swabs are ideal for cleaning all PVC/PUC and silicone tracheostomy and laryngectomy tubes. The soft, smooth heads of the swabs will not scratch or damage the internal tube surface. The foam heads of the swabs are better suited for cleaning tracheostomy tubes than cotton tipped swabs as there are no loose fibers. Trachi-Swabs feature a flexible plastic shaft to allow ease of movement inside the cannula.
