Blom-Singer® Classic Indwelling
Clinical application
The Blom Singer® Classic Indwelling prosthesis is made entirely of silicone with no reinforced shaft. Insertion with the gel capsule is atraumatic and flexible. The valve is slightly prone to shear stress. The esophageal flange contrasts in x-rays. European designs give the shaft length in mm on the tracheal flange. The 20 fr design of the Blom-Singer® Classing Indwelling prosthesis is approximately the same as the Provox 2 in use, and despite the minor difference in the outer shaft diameter they can usually be used as a substitute for each other.
