Marpac Inc Bariatric Tracheostomy Collars 2" W, Two-pieceMarpac does all of its design and manufacturing in the United States so we are able to take your patient's measurements and make a tracheostomy collar specifically for them in just one day! And, as with all of Marpac's tracheostomy collars, we use the softest, most comfortable material. No more "build your own", "make it work" or possible patient wounds. Don't struggle to make a regular collar "fit" your larger patients. Regular collars can dig into your patient's skin causing wounds. Use a wider, longer collar made just for your patient.
